Neumann, Fire Chief Subject: UNOCAL Update Fire Staff now has the complete action plan for the Avila Beach clean-up. Spencer Meyer will now be sitting in on the weekly agency update meeting. At Ken's request, I spoke with the Mayor on Friday and passed along our involvement. At this time, Allen's major concern centers on long-term storage and treatment at the Prado Road site. The long-term storage plan is due to the County within the next day or two. As soon as we get it, it will be reviewed and I'll be better able to address the Mayor's concerns.

BaldridgeCalifornia Regional WaterQuality Control BoardCentral Coast RegionLIA2 A Laurel LaneSan Luis Obispo, CA 93401 RE:Unocal PipelineSan Luis DriveSan Luis Obispo Dear Mr. Baldridge: Unocal Corp is responding to a letter dated January 9, 1991 fromthe Regional Water Quality Control Board requesting submittal ofa complete soil remediation plan. This proposal addresses crudeoil contamination from a Unocal pipeline leak caused by a City ofSan Luis Obispo contractor during a street upgrade project in1967. Evaluation of cleanup possibilities indicates that noactive remediation alternatives are appropriate at this site.Unocal proposes monitoring the immcbile crude oil contamination.Well protection wiII be rnstalled in the unlikely event thathydrocarbon begins to migrate. Numerous remediation alternatives have been considered inpreparation of this plan. Alternatives evaluated on a technicaland cost basis include containment, vitrification, stabilization,chemical treatment, vacuum extraction, soil washing,bi-oremediation, and excavation. None of these methods alone wouldbe capable of remediation of all the identified soilcontamination to the cleanup l-evel of 2OO parts per million totalpetroleun hydrocarbons being considered by the Regional WaterQuality Control Board. Primary drawbacks to these methodsinclude, surface disruption, railroad location, subsurfacecontrol of chemical and biological reactions and movement, soilpermeability, achievable Ievels of contaminant reduction, andtime frames, Considering the developed nature of the site, depthand lateral extent of the soil contamination, physicaL andchemical characteristics of the contaminated soil, technologicallimitations and possibl-e environmental risk of the methods, thesealternative were determined to be impractical, unfeasible, unsafeor inappropriate. qtaPl Page TwoMr. B. BaldridgeMay 14, 1991 Unocal proposes that monitoring and water weII protection is themost appropriate action for this site. The basis for thisapproach is a groundwater monitoring program that wilI detectcontamination movement if it occurs. Unocal is prepared toimplement appropriate measures to protect the quality ofgroundwater that may flow into a future supply weII fronr thespill- area. These measllres include a weII water purificationsystem at the wellhead and extraction and infiltration weIIs tointercept and control flow of groundwater towards the San LuisObispo High School well if the contaminants begin to move. Theseplans were outlined in a previous report to the Regional WaterQuality ControL Board. A monitoring and protection approach is supported by the age ofthe spill, lack of a continuing source of contamination, thenon-hazardous nature of the crude oil contaminationr lack ofwidespread elevated levels of benzene, toluene, xylene andethylbenzene compounds in soil or groundwater and irnmobility ofthe crude oil constituents. Asphalt and concrete surface cappingand low permeability soils in the upper alluvial sectionunderlying the site minimize the potential forIeaching of contarninants from infiltrating surface water. Of mostimportance is the immobil-ity of the contamination established byfour separate groundwater sampling events conducted sinceJanuary, 1990 that demonstrate no detectable presence ofdowngradient dissol-ved contaminant. Our next quarterly groundwater monitoring report wiII besubnitted in June. f would be happy to meet with you to discussour evaluation of cleanup alternatives, monitoring and wellprotect ion.

L99I. Inthe Report on Table 3 (Enclosed) it is reported up to L7.7O feet ofcrude oil product are on the water table in fifteen (15) of theonsite groundwater monitoring we1Is. Until further notice, w€request Unocal regularly bail or pump the crude oil from thernonitoring wells and reclaim it if possible. There seems to be some misunderstanding regarding the nature of thecrude oil contamination spread throughout the Tank Farm Road site.Unocalrs consultant, Groundwater Technology, Inc., states the crudeoil currently present onsite is not a coherent body of oil floatingon the groundwater, but is contained within fractures andstratigraphic lenses now encapsulated by degraded crude oil. Thisobservation is not consistent with what is reported by EarthSystems Environmental, Inc. on the enclosed Table 3, nor asobserved by Board staff. On February 25, L992, Richard Ateshire ofthis Boardrs staff observed medium viscosity crude sil in a pumptest well next to onsite monitoring well TMW-I. Unocal must remove all recoverable free product crude oil from thissite. To implement this, we reqluested Unocal subrnit, a workplan andtime schedule detailing how free product crude oil will be removed.from soil and groundwater. Another matter of concern is the amount of surface water pondedonsite during wet-weather months. On February 25, 1992, tens ofacre-feet of ponded ra,inwater were noted in several areas overlyingcontaminated soil areas. Water ponded onsite further threat,ens todrive petroleum contaminants in soil into groundwater or surfacewater. Petroleum contaminants in soil should be hydrologicallyisolated from surface water as much as possible. Mr. John Ljuncr -2-March 23, L992 on or before April 20, L992, vre request submittal of a workplan andtime schedule for grading the site so rainfall water ana runoffwater is diverted offsite away from contaminated soiIs. pondedwater should not be retained onsite, unress in rined ponds. Request for the workplan and time schedule for needed sitemodifications is made pursuant to Sections L3267 and 13300 ofcariforniars Porter-cologne water quarity contror Act.

Michael J. FINAL ro/3let 0z23fp,59L Paul A. McCaw Environmental Health Scientist Senior Project Manager Principal Director, Risk Assessment l:l I EXECUTIVE SUMMARY FINAL This risk assessment evaluated the potential human health risks associated with the presence of weathered crude oil in soils beneath Pismo and Beach Streets in San Luis Obispo, California. The health risk assessment was performed as part of the ongoing site characterization by Unocal Corporation Refining and Marketing Division. Previous phases of work have included an initial site assessment in 1989-1990 (including soil and groundwater analyses) and a Phase 2 site assessment conducted by Groundwater Technolory in 1990-1991. The Phase 2 site assessment included, but was not limited to: (1) soil and groundwater analyses, (2) geophysical analyses, (3) a soil gas survey, (4) a groundwater usage and well survey, and (5) compositional analysis of extracted hydrocarbons. The purpose of the health risk assessment was to conservatively estimate the potential health risks associated with components of weathered crude oil beneath the site and evaluate the potential environmental fate of these compounds in both vadose and saturated zones. Based on the evaluation presented in this report, Envirologic Data concludes that there are no significant health risks associated with this site as it currently exists. All estimated health risks are below de minimis or acceptable maximum levels. The maximum estimated cancer risk associated with this site is nearly two orders of magnitude less than the ma:cimum acceptable risk of 1. in 100,000 clictated by California Proposition 65 (the Safe Drinking Water and Toxics Enforcement Act of 1986); the estimated upper-bound cancer risk associated with this site is 3.3 x 10-? for inhalation of dust by pipeline maintenance workers. The composite risk for pipeline maintenance workers is 4.5 x 1'04- The marcimum estimated non-cancer hazard inclex (HI) associated with this site (0.0006) is more than three orders'of magnitude less than the maximum allowable HI of 1.0. The composite HI associated with this site is 0.00005. Due to the conservative nature of this evaluation, it is likely that both potential cancer risks and HIs are even lower than estimated in this report and may be as low as zero. The source of the chemicals at the site was iclentifiect as a weathered crude oil (GTI, 1991). The toxicity of crude oil can be interpretecl as the toxicity of a complex mixture of inorganic and organic chemicals. The toxicity of mixtures may be evaluated in either to/3ler 022ffi591 iii FINAL of activity would be a one-time event (as opposed to potential repeated exposures associated with pipeline maintenance). TABLE F.-2 (page v) presents the exposure pathways and receptor populations evaluated in this assessment. The estimated composite risk to the pipeline maintenance workers is 4.5 x 10s. The range of risks for the reasonable maximum exposure scenarios (RMEs) is 5.3 x 1.0-13 to 3.3 x 10-7 for inhalation of vapors and inhalation of dust respectively. The total risk associated with potential exposures to benzene by residents is 2.5 x 10-rr for the average exposure and 3.9 x 10-10 for the RME. See TABLE E-3 (page vi) for a summary of average risks estimated in this evaluation. The composite hazard index for the pipeline maintenance workers is 0.00005. The total hazard index for residents exposed to all chemicals through inhalation of vapors in homes is 0.000001 for the average exposure and 0.000005 for the RME. TABLE E-4 (page vii) provides the HIs for average exposure scenarios for pipeline maintenance workers and residents. The duration, frequency and intensity of potential exposures to toxic agents in various environmental matrices are evaluated when quantising the close received by potential receptors. Attempts are made to select parameter values which accurately reflect the actual site conditions. However, the absence of site-specific data requires that values for some exposure parameters be estimated. When it was necessary to estimate values, conservative estimates were used in order to insure the full protection of human and environmental health. Due to these conservative exposure estimates, the corresponding estimates of risk are likely to be higher than would be expected under actual site conditions. TABLES E-5 through E-7 (pages viii through x) summarize the conservative exposure parameters used in this risk assessment. Due to the low estimated health risks associated with the Pismo and Beach Streets site and the lack of potential migration to saturated zones, Envirologic Data concludes that no remedial action of the weathered crude oil (or chemical components) in soils is necessary.

This proposal addresses crudeoil contamination fron a Unocal pipeline leak caused by a City ofSan Luis Obispo contractor during a street upgrade proiect in1967. Evaluation of cleanup possibilities indicates that noactive remediation alternatives are appropriate at this site.Unocal proposes monitoring the inmcbile crude oil contamination.Well protection will be rnstalled in the unlikely event thathydrocarbon begins to migrate. Numerous r.emediation alternatives have been consiclered inpreparation of this p1an. Alternatives evaluated on a technicaland cost basis include containment, vitrification, stabilization,chemical treatment, vactlum extraction, soil washing,biorenediation, and excavation. None of these methods alone wouldbe capable of remediation of all the identified soilcontamination to the cleanup level of 200 parts per million totalpetroleum hydrocarbons being considered by the Regional WaterQuality Control Board. Primary drawbacks to these methodsinclude, surface disruption, railroad location, subsurfacecontrol of chemical and biological reactions and movement' soilpermeability, achievable levels of contaminant reduction' andtime frames. Considering the developed nature o'f the site, depthand lateral extent of the soil contamination, physical andchemical characteristics of the contaminated soil, technologicalIimitations and possible environmental risk of the nethods, thesealternative were determined to be impractical, unfeasible, unsafeor inappropriate. Page TwoMr. B. BaldridgeMay L4, 1991 Unocal proposes that monitoring and water well protection is thenost appropriate action for this site. The basis for thisapproach is a groundwater monitoring program that will detectcontamination movement if it occurs. Unocal is prepared toimplement appropriate measures to protect the quality ofgroundwater that may flow into a future suPply weII from thespilf area. These measlrres includ.e a well water purification system at the wellhead and extraction and infiltration wells tointercept and control flow of groundwater towards the San Luis Obispo High School wetl if the contaminants begin to move. Theseplans were outlined in a previous report to the Regional Water Quality Control Board A monitoring and protection approach is supported by the age ofthe spill, lack of a continuing source of contaminationr thenon-hazardous nature of the crude oil contaminationr lack ofwidespread elevated levels of benzene, toluene, xylene and ethylbenze111e compounds in soil or groundwater and immobility ofthe crude oil constituents. Asphalt and concrete surface cappingand low permeability soils in the upper alluvial sectionunderlying the site minimize the potential forleaching of contaminants from infiltrating surface water. Of mostimportanee is the immobility of the contamination established byfour separate groundwater sampling events conducted sinceJanuary, 1990 that demonstrate no detectable presence ofdowngradient dissolved contaminant Our next quarterly groundwater monitoring report will besubmitted in June. I would be happy to meet with you to discussour evaluation of cleanup alternatives, monitoring and wellprotection. Sincerely t John R.

This letter is in response to your request that UnocalCorporation provide written assurance that a water treatmentsystem wiII be installed, if needed, to protect the high schoolwater supply welI. Unocal has begun monitoring the groundwaterin wells between the hydrocarbon plume and the high school well#3. If plurne movement is detected after pumping of the highschool well begins, either a weII water treatment system or agroundwater extraction and infiltration system will be installedto ensure that water produced from high school well #3 is free ofhydrocarbons that originated from the pipeline leak site. Installation of the supply well treatment system wiII reguire twoto three weeks after permits have been received. Architecturaland building permits will be required. Permitting will beginimmediately based on providing treatment of 100 gallons perminute. We assume that you will grant Unocal permission tolocate the needed facilities on the High School site. Installation of the groundwater extraction and infiltrationsystem will require four to five weeks. Permitting will begin assoon as the additional data needed for design has been collectedfrom a site investigation on the Southern Pacific Transportation IA q DecemberPage TwoMr. B.

Based on previous analytical information provided, UNOCAL proposed a couple of clean up alternativei that includeO; t; excavation and above ground bioremediation,2) in-situ bioremediation. Both of these scenarios were discussed at length. In order to develop an appropriate clean up plan, UNOCAL proposed to conduct a Risk Assessment to establish a health-based clean up level for Total Petroleum Hydrocarbons (TPH), for this particular site and material. The City stressed it's position that acceptable clean up levels are 100 part per million (pp.) for TPH- fhis level is required for current as wei as previous contaminated site of this nature. Additionally, UNOCAL was informed that all regulatory decision regarding this site will be made at a staff level. For your information, attached is the latest response from UNOCAL regarding the investigation and clean up of this site.

Based on a telephone conversation with Mr. David Ragsdale of the San Luis Obispo County Department of Health, Division of Environmental Health on August 3, 1990, the soil cuttings containing TPH concentrations above 100 mg/kg could be incorporated into the existing bioremediation treatment cell located on UNOCAL's tank farm property at 276 Tank Farm Road in San Luis Obispo County. Copies of the analytical results are attached for reference. Also attached is a table presenting the number of drums corresponding to each boring, along with the laboratory results and recommended treatment or disposal method. A total of twenty eight (28) 55-gallon drums of soil cuttings were transported from the San Luis Drive site to the tank farm. Of the 28 drums, 12 contained soils with TPH concentrations above the RWQCB's Action Level. On August 6, 1990, the l2 drums of soil were incorporated into the existing bioremediation cell at the tank farm. The remaining 16 drums containing TPH constituents less than 100 mglke can be spread out as fill material. We suggest that the 16 drums of soil be spread out on the tank farm property.

The risk assessment is intended to be part of, and not in lieu of, a detailed site assessment and remediation plan. In a letter dated July 9, L990, the City determined that the site should be remediated without the benefit of tLe risk assessment. I understand that this decision resulted from discussions between the fire department and the City Attorney's office. The purpose of this letter is to provide you further information on the importance of risk assessment to environmental remediation. It is the philosophy of Envirologic Data, and myself, that if environmental decision- making lrist management) is going to be protective of human health, then potential healthlmpacts nee-cl to be evaluated. The human health risk assessment proposed by Envirologic Data for the site will provide this evaluation. The risk assessment will contain an evaluation of the compounds present at the site, potential routes of exposure to people and potential health efiects. With this information, decisions which protect the community can be made. In a phone conversation with Mr. Smith, the question of potential liability for the City was iaised. The quantitative human health risk assessment can provide the legal documentation to the City which minimizes liability. The risk assessment will set conservative, health protective goals for the remediation of the site. By applying these proposed levels to the Beach and Pismo street site, the City can be sure that human ir"uittr is being protected. Can the same conclusion be reached when an arbitrary, non- site-specific criteria is used instead of a health-based criteria? I would like the opportunity to come to San Luis Obispo and provide a detailed discussion on the uie of rist assessment in environmental remediation. I believe that thiough discussions, I can demonstrate the usefulness of risk assessment. I will be folo#ng up with atelephone call in the next couple of days. Please call me if you have any queJtio6 o, want any further information. I look forward to meeting you and ptouiAitrg the City with a risk assessment on the Beach and Pismo street site.

The policy indemnihes the buyer from loss of title,and therefore guarantees ownership (within thelimits set out in the policy). Title insurance is, in themain, based on title research, and is. with rare exception, paper an owner has that never w,ill be needed. With the increase in recognition of environmental contamination and specific contaminants, there is a threat of new dimensions to some property owners. Successful tort litigation may result in a property owner being the recipient of a judgment for several times the value of the property over which the claim arose. This can develop, without the owner's knowl- edge, from polluted land, water or air found to be in, or emanate from, a piece of real estate. Due diligence may not be an adequate defense. This article will explore the alternatives a prop- owner may take to minimize liability flom the existence of contaminants on his property, what is to come.of the arresting features of these rnulti- dollar judgments is that quality standardsfor pollutants currently proscribed often are set at levels that are far below the detectable limits for those substances by analytical procedures that werestate-of-the-art early in the careers of today's mature chemists. As a consequence of today's analysts' ability to measure things present in minuscule levels, there has been an ever-widening awareness of the exis- tence of a multiplicity of potentially harmful sub- stances in the environment. Some ofthese, such asaflatoxin, may cause banning of agricultural prod- ucts because ol naturally occurring contaminants not known to be in these foodstuffs a few years back. We lack completely definitive information on the consequences of long-term, low-level exposures toenvironmental contaminants of any kind. "Risk assessments" ol these environmental pollutants are made commonly on the basis of short-term, high- Ievel exposures. Cancer deaths are freeiy predicted on the basis of the same studies. Current water standards for some halogenated hydrocarbons are at the nanogram (0.000,000,001) per milliliter level. For a typical compound of this type, only 0.2 of a drop need be added to a freight car of water to attain this level.The old saying in toxicology, "the dose is thepoison," may show the skepticism in some that apicogram dose a day on something non-accu-mulative is a dire threat to one's health. But toxictolt ag,ards have been macle on the lear of cancer resulting from a possible exposure to a carcinogen!Ifyou buy a building today with borrowed funds,the prudent lender will require that you have theproperty inspected.

This investigation was performed to deter-mine the extent of soil containing petroleum hydrocarbons in thesubsurface of the area. The work was performed at your request and inaccordance with the work plan submitted to your agency on December 4t1989. As you knowr orl February 8, 1990, Mr. Robert McElroy of UnocaltMr. Tom HoIIis of GeoResearch, and I met with you and Gary Henderson,City of San Luis Obispo, Public l{orks Department to discuss thepreliminary findings of this report. Per our conversation of thatmeeting: Unocal feels that Lhere is not any evidenee found in thisinvestigation to suggest that our pipelines are a source of the soilcontamination in the area of t,he E-Il<s Lane bridge. The investigation finds that the soif between ground surface and 18 to23 feet below ground surface ( bgs ) in the area south of the Elks lanebridge does not appear to be impacted by hydrocarbon compounds andsoil samples from this interval contained total recoverable petroleumhydrocarbon (TRPH) concentrations between not detected and 110milligram per kilogram (rng/kg). Soil below 18 to 23 feet bgs,however, was stained and had a strong hydrocarbon odor and samplesfrom this interval contaj-ned TRPH concentrations ranging from notdetected to 1600 ng/kg. Based on these results, it does not appearthat the soil in this area was contaminated by a source near thesurface ( i. e. Unocal pipelines ) . 1987 andLane April 16, 1990Page Two bridge was completed in January 1988. No evidence of staining in thepipeline ditch was noted by Unocal personnel during the replacementwork. The pipeline renewal on the north side of Elks Lane bridge wascompleted in April 1988. During that constructionr Unocal employed anOilfie1d Engineering and Consulting, Inc. registered geologist toconduct soil sampling using an Organic Vapor Analyzer (OVA) along thepipeline ditchr p€r the request of your office. The survey did notreveal contamination at pipeline depth in that area. The results ofthat survey are on file in your agency office. That data wouldsupport that. soil south of the bridge was not contaminated as a resultof pipeline l-eaks north of the bridge. Historicall)', lJnocal has had laboratory ana]yses performecl on so j 1sanrples at oLher site investigations where the loss of peLroleum fromour pipelines has impacted soil. These other sites include theintersection of Pismo and Beach, San Luis Drive, and Buckely Road.The laboratory analysis on soil from those sites included; the testingfor purgeabfe aromatics in accordance with EPA rnethod BZ4O, andtesting for semi-volatil-e organics in accordance with EPA method 8270.The analytical test results from those sites and the EIk Lane sitewere compared. The EIks Lane petroleum stained soil was found tocontain significant concentrations of compounds not found in thepetroleum sLained soil at our other sites; nor is it believed thatLhese compourrds would be normally resident to the petroleum wetransport. These compounds include acetone, 1,1-Dichloroethane, 1,2-Dicholorethane. 1 , 1, 1-Trichloroethane, and Phenanthrene. ThisdaLa suggests that the source of soil contamination at the Elks Lanebridge may not have been from the Unocal pipeline. In summar)-, Unocal believes that our pipelines are not the source ofsubsurface contamination found in the Elks Lane bridge and San LuisObispo Creek area. We support our claim with site investigation dataand historlcal data. That data includes: 1 No significant contaminationsurface to IB-23 feet bgs as found in theevidenced in soil from groundthe attached reporL D No staining or contamination found during Unocal pipelinereplacement work in the area.

As you knowr orl February 81 1990, Mr. Robert McEIroy of Unocal,Mr. Tom Hollis of GeoResearch, and I met with you and Gary Henderson' City of San Luis Obispo, Public Works Department to discuss thep".timinary findings of this report. Per our conversation of that meetingl Unocal feels that there is not any evidence found in this investiftation to suggest that our pipelines are a source of the soil contamination in the area of the Elks Lane bridge ' The investigation finds that the soil between ground surface and 18 to 23 feet below ground surface (bgs) in the area south of the Elks lane bridge does noi appear to be impacted by hydrocarbon compounds and soil samples from this interval contained total recoverable petroleum hydrocarlon (TRPH) concentrations between not detected and 110milligram per kilogram (ng/kg). Soil below 18 to 23 feet bgs, however, was stained and had a strong hydrocarbon odor and samplesfrom this interval contained TRPH concentrations ranging from notdetected to 1600 mg/kg. Based on these results' it does not appearthat the soil in this area r^ras contaminated by a source near thesurface (i.e. Unocal piPelines). lateElks 1987 andLane April 16 ' 1990Page Two bridge was completed in January 1988. No evidence of staining in thepipeiine dit,ch was noted by Unocal personnel during the replacement*""t . The pipeline renewal on the north side of EIks Lane bridge was completed in April 1988. During that construction, Unocal employed an Oiliield Engineering and Consulting; Inc. registered geologist toconduct soil sampling using an Organic Vapor Analyzer (OVA) along thepipeline ditchr per the request of your office. The survey did notreveal contamination at pipeline depth in that area. The results ofthat survey are on file in your agency office. That data wouldsupport that soil south of the bridge was not contaminated as a resultof pipeline leaks north of the bridge. Historically, Unocal has had laboratory analyses performed on soil samples at other site investigations where the loss of petroleum fromour pipelines has impacted soil. These other sites include theintersection of Pismo and Beach, San Luis Drivel and Buckely Road.The laboratory analysis on soil from those sites included; the testingfor purgeable aromatics in accordance with EPA rnethod 8240, andtesting for semi-volatile organics in accordance with EPA method 8270. The analytical test results from those sites and the Elk Lane sitewere compared. The EIks Lane petroleum stained soil was found tocontain significant concentrations of compounds not found in thepetroleum stained soil at our other sites; nor is it believed thatthese compounds would be normally resident to the petroleum wetransport. These compounds include acetone, 1,l-Dichloroethane, 1,Z-Dicholorethane. 1, 1, 1-Trichloroethane, and Phenanthrene. This d,a;a suggests that the source of soil contamination aL the Elks Lanebridge may not have been from the Unocal pipeline. In summary, Unocal believes that our pipelines are not the source ofsubsurface contamination found in the Elks Lane bridge and San Luis Obispo Creek a.rea. We support our claim with site investigation data and historical data. That data includes: 1. No significant contamination found in the soil" from ground surface to 18-23 feet bgs as evidenced in the attached report. Z. No staining or contamination found during Unocal pipelinereplacement work in the area. Geotechnical consultant dataon file in Your agency office. Compounds found in soil contamination at this site not foundin soil contamination from previous sites.3 April 16 ' 1990Page Three Should you have any questionstfurther action on Unocal's Part ( 805 ) 543-5026. or wish to discuss thisin this matter, Please report, or wishcall me aL S incerely ' P.

Data provided indicates that a partially refined petroleum product has been released from Unocal's underground pipeline(s). Furthermore, the report has characterized a plume that extends in all directions of the now closed pipeline(s), which has impacted both City and residential properties. Therefore, in order to address this matter, this department will require the submittal of a Remedial Action Plan consisting of the following: 1) Clean-up method to be used, 2)Identi$ professional consultants, contractors, labs, clean-up companies and haulers to be used, 3) If the material is going to be removed, provide its final destination, (State permitted disposal site, treatment or recycling facility, or other approved location), 4) Date work is scheduled to begin and completed, 5) Necessary permits from applicable agencies (City, County, State, Federal). Note: This plan shall be submitted to the San Luis Obispo Fire Department for review no later that May 1, 1990. Also, approval is required from this office prior to implementing clean up activities.

The following is a summation of each area: San Luis Drive @ SLO High School During the installation of the new pipelines along SLO Dr, moderate to very strong concentrations of petroleum hydrocarbons were encountered in the soils. Initial soil investigations revealed extremely high mncentrations of petroleum hydrocarbons along SLODr., in front of the staff parking lot. At this time, a full site investigation has been completed and the plume area defined, however no source has been determined. The final investigation report should be submitted next week Elks Lane @ Elks Lane Bridge During routine drilling operations for civil engineering purposes, moderate to strong concentrations of petroleum were detected in the soils and ground water on the southwest side of the Elks Lane bridge. Further site investigations revealed that soil mntamination is limited to the areas below 18 feet. As of yet, a site investigation has been completed, however no souroe has not been determined. Unocal is taking the position that this is notfrom their pipeline because of the following reasons: In 1988, the old pipeline was replaced along Elks Lane with no indication of soil contamination within 5 feet of the surface. I-aboratory analysis have identified other mntaminants not associated with their use, i.e. TCA Apparently this area (around the bridge) was once a landfill, and material may be leaching from there. 1. 2. 3. A final investigation report should also be submitted next weelc Pismo and Beach Street A full site investigation has been mmpleted and submitted for review. The following are highlights of that report: The source of the TRPH (Total Recoverable Petroleum Hydrocarbon) in the soil appears to have been at or near the ground surface in the area of the intersectionof Pismo and Beach Streets. Soil containing TRPH in this area extends to the shallow water table at approximately ?3 feet bgs. Hydrocarbon concentrations range from ND (non detectable) to 9,200 ppm. (City action levels are 100 ppm) The plume of soil containing TRPH concentrations is estimated to be 70 feet wide northwest and southeast of the intersection along Beach Street (Attached). The top of the soil interval containing TRPH deepens outward from the intersection. The plume of soil containing.TRPH concentrations appears to terminate near the northeast side of the intersection (Attached). The plume of soil containing TRPH has preferentially migrated southwest of the suspected source area (Attached). This migration direction parallels Pismo Street and is topographically downgradient of the intersection. The lateral extent of soil containing TRPH southwest of the intersection cannot be defined by the results of this investigation; however, soil samples collected from borings approximately 7O feet southwest of the intenection contained TRPH concentrations distinctly lower than those of the soil samples collected beneath the intersection, but still exceed City action levels. The hydraulic gradient of the shallow aquifer at the site suggest the direction of ground-water flow is to the southwest. TRPH concentrations were not detected in the ground-water samples collected from the wells on site. However, well MW4 was not sampled because it contained approximately 3 inches of free product during and immediately following the drilling and well installation. The ground-water elevation in the well at this time was approximately 14 feet bgs. In January, 1990, free product was not detected in the well and the ground-water elevation was approximately 23 feet bgs. Based on these results, a clean-up order will be issued for this site.

Off the discharge side of the UNOCAL pump, DS will run a 2tl150 psi working pressure (300 psi test) rubber lined hose to oneof the tanks on the DS rr3 tankerrr (3-1000 gallon rubber linedtanks) . This will be known as line rrArr. 3. From this truck tank, a 3rr rubber lined suction hose (150 psiworking pressure) will be connected to DSts truck mounted pump.This will a1low the contents from the truck tank to be pumpedinto the suction side of the ITNOCAL circulation pump. 4. Another 2rr I50 psi working pressure rubber lined hose will berun from the discharge of the DS truck mounted pump to a 2ttconnection on the suction side of UNOCALTs circulation pump.This will be known as line rrBrr. 5. When the DS Service Supervisor indicates to UNOCAL that DS isready, UNOCAL should start circulating the pipeline with theirpump. THE DS Service Supervisor will open the valve on line rrArrwhich will put, water into the DS truck tank. DS will start thetruck mounted pump and open the valve on line rrBrr and start,pumping the water from the truck tank back j-nto the pipeline. Byregulating valves |tArr and rrBrr, DS can pump water out of the trucktank at the same rate its coming into the tank via line rrArr.This is referred to as a ttslip streanl. t Page 2 6. After the rrslip streamrr and pipeline circulation have beenstabilized, the hook up will be checked for any leaks and any found will be fixed. 7. At this point, chemical are introduced into the system byrnixing them in tnl DS truck tank using water from the pipeline. -via line rrArr and pumping the chemical/waEer mixture back into thepipeline via line- rrgir. This will be continued until all the-cninicats are rnixed and in the pipeline to be cleaned. NOTE z 4 different chemicals will be used on this job, 2 ateliquid and 2 are dry. The 2 liquid chemicals are MOOT (liquid caustic) and F057 (surfactant)' Tl" MOOZ wiff be pumped irom its storage container intothe truck tank using a diaphrag[n pump and 1-rr 150 psiworking pressure rubber line hose. The FO57 comes in5 gallon-containers and it will be poured into thetrrlck tank from them. The MOOS and M182 are dry andwill be added. to the truck tank by cutting the sackwhile it is over the opening of the tank. 8. After all the chemicals are mixed, the level in the trucktank will be lowered by closing off on valve rrArr. The truck tankwill then be washed ouL with clean water and pumped back into thepipeline to be cleaned. g. UNOCAL will continue to circulate the pipeline using theirpump for the next 6 hours. Discharge pressure wilt be monitoredon Lne uNocAL pump throughout the circulation period. 10. After 6 hours of circulation, the pipeline will be shut inovernight and allowed to soak. DS and. UNOCAL people will securethe pipeline and area then leave location for the night. At !li"timel there will be no chemicals at the site except the solutionsecured inside the pipeline being cleaned- 11. The next morning, UNOCAL will circulate the pipeline for twohours before displacing the chemical solution out of thepipeline. L2. To displace the chemical solution out of the pipeline, apoly pig wilf be launched into the pipeline and pushed down the bipefi-ne with fresh water. This will enable the chemical-solution to be displaced with a rninimum amount oL qater. Thiqprocess may need rA be repeated a second iile. ,(*!,'!*.r,1,(;),:';;;J;*,f JjJ.U., u,) 13. While fresh water is being injected into the pipeline, thecleanj-ng solution will be directed from the pipeline into BakerTanks via DS 3rr 150 psi working pressure rubber lined hose. See Page 3 attachment #Z for a flow diagram. Each Baker Tank wiII belirnited to 360 barrels, this will leave two feet of free boardafter neutralization. 14. DS will monitor the pH of the fluid coming out of thepipeline and w,iII s.top the. flush whgn the nH reaches acceptableiiilir;. ue+.;Z;'6;;";Jt- -;i';/ "'J':';J' )- ier;x;;-b'r -c';J"cE ( r'/-r*/.-{ k:L) l-5. After the pipeline has been flushed of all chemicals, the-waste solution wilf be impounded in several Baker Tanks. DS willcheck the pH of aII the tlnks containing waste and balculate theamount of acid needed to lower the pH to acceptable levels. 16. To lower the pH of the waste solution, air lances vrill beput into the Baker Tanks to aid in circulating them for acidadd.ition. The acid will be stored in a DS transport truck and pumped. into the Baker Tanks using DSrs truck mounted pump.. Thelcid injection rate will be slow and the pH of the waste will bemonitored continuously. The hose used to pump the acid will be150 psi working pressure rubber lined hose L7. After the Baker Tanks have been neutralized to acceptable pHIevels, DS will flush out the truck mounted punp and hose andpump wash water to a Baker Tank (capacity - 200 gallons). DSwiff then rig down its eqrripment and leave location. Disposal ofthe neutralized waste is UNOCALTs responsibility.

LeonardExecutive Officer Dear Mr. Leonard: Unocal has encountered contaminated soil on San Luis Drive in SanLuis obispo. We have previously notified the California RegionalWater Quality Control Board (Board) verbally of this contaminationon August 9, 1989 and with written notification on August 15'1989. The material that was excavated is being stored at our SanLuis Obispo Tank Farm located at 276 Tank Farm Road. Weanticipate encountering further contaminated soil in San LuisDrive as our pipeline replacement progresses. Unocal has testedthe contaminated material and has determined the material to benon-hazardous per Tj-t1e 22. Copies of the test results wereforwarded to the Board on September L, 1"989. It is our intent to transport any additional contaminated soilfrom the site to our Tank Farm Road location. The City of SanLuis Obispo has stated that all contaminated soil is to be treatedas a hazardous waste and that prior to removal, Unocal mustidentify professional consultants, Iabs, clean-up companies andhaulers to be used. The Environmental Health Department has citeda letter dated September 22, 1988 from the Board to Mr. RoyAlexander of the Santa Barbara County Health Department as thebasis for treating this material as hazardous. In that letter,the Board stated that material with a Total Petroleum Hydrocarboncontent of 1000 ppm or greater should be treated as a hazardouswaste. Unocal requests the Board review the applicability of thisstandard to the contamination encountered in San Luis Obispo.Application of the same standard would require the storage ofencountered contaminated soil at the San Luis Obispo High Schoolsite while laboratory analysis is performed. Regional Water Quality Control BoardSeptember 7, L989 !Page 2 Once the material is at the Tank Farm location, itto use it as road base. Based on p::evious submittamaterial for road base, the fotlowing information i 2. 4 5 l-s1s s our desirefor use ofprovided: L The site at which the material will be used is Unocalrs SanLuis Obispo Tank Farm located at 276 Tank Farm Road in SanLuis Obispo. The material will be used solely at, and willbe retained on this site. The material we propose to use as road base is thecontaminated soil fiom San Luis Drive. The maximum quantityof material we will use is 300 cubic yards- _ A competent agent will be present throughout the mixing andspreading of the road base. Our proposed plan for use of this material is to spread itevenly in a contained area. Road oil will be mixed with thesoit using vacuum trucks. After each truck load is applied'the area will be mixed and ad.ditional soil applied asrequired. We certify that any other necessary permits will be obtainedand maintiined. It is our understanding that writtennotification of approval from the Board is the onlyauthorization neceisary for this work. By a copy of thisletter to San Luis Obispo County, Division of EnvironmentalHealth, we request any information to the contrary- We certify that we will submit such monitoring and technicalreports related to this work as may be required by theExecutive Officer. Please inform us of any such reporting atyour earliest convenience. We certify that Unocal (Union Oil Company of California) isthe owner of the facility at which the deposit and use ofthis contaminated soil will be made. 3 6 7. Based upon the information, analysis and certifications submitted,we respectfully request the Board issue written notification ofapproval.

The letters to residents and busi- nesses on Pismo Street and San Luis Obispo Drive sLated that portions oflwo steel pipelines running undertheir streets were going to be re- placed by new pipes running along- side the old ones."I was a little alarmed," said Pismo Street resident Rene Tanner. "I didn't even know there was an old pipeline mnning through here." The 8-inch pipelines begin at Cues- ta Grade and runs ali the way through the city, said Robert McElroy, district superintendent for Unocal's coast area pipelines. The pipes were laid in 1910 and upgraded once in the 1940s. "This is an ongoing process, which is done as preventive maintenance," McElroy said. The replacement will begin Aug. 7 and take an estimated seven weeks.On top of the inconvenience of having their street ripped up, resi- dents fear for their safety."I worry about the San Bernardino deal happening in a residential neigh- borhood," said Tanner.TVo people were killed and 10 homes destroyed when a pipeline carrying gasoline under a San Ber- nardino neighborhood exploded May 25. The pipeline was allegedly dam- aged by a trail derailment a week earlier that killed four and destroyed six homes.McElroy responded that the SanBernardino disaster happened be- cause damage to the pipeline was not discovered."If we had a similar circumslance, our policy would be to do a complete inspection, which was not done in the San Bernardino accident," said McEl- roy.He also said the San Luis Obispopipeiines carry a less flammable substance - crude oil and partially refined oil.The decision to replace the pipe was sparked by a small leak near San Luis Obispo High School in January of 1988. "We wanted to get this done before we encountered any more problems," said McElroy. Once the new pipes are laid, Unocalwill clean and decontaminate the old pipelines before turning them over to the city. The city plans on using the pipes, sometime in the future, to carry treated sewer water for irrigation.It would cost the city some $500,000to lay such a line, said Public Works Director David Romero. Unocal bene- frts because it won't have to remove the line, but merely clean it."It's a bit unusual," said Romero."But we're real pleased with it. It stands to save the city quite a bit of money in the future and Unocal some money now." l'l ,, "'; t ),-/'"'' :=* Unocal Pipeline ComPanYA Unocal Company1201 W.Sth StreetLos Angeles, California 90017 UNOCAL@August L, 1989 SUBJECT: PIPELINE CONSTRUCTION Dear Resident / Business Owner: PISMO STREET AND SAN LUIS DRIVE Union Oil Company of Califcjrnia (Unocal) maintains and operates two (2) eight :-ncrr diameter steel pipelines through the city of San Luis O6ispo.

Borings were drillcd to assess subsurface conditions and to obtain samples for laboratory analysis. The two borings were drilled behind the cxisting bridge abutments, approximately on the ccnter line of the existing strect. The borings revealed profilcs of clay with varying amounts of sand silt and gravel; with free water at dcpths of l8 and 25 feet, respectively. When Boring I was drillcd at the north end of the existing bridgc, visible and olfactory evidence of. petroleum products was found at depths of l8 to 23 feet bclow existing strcet grade. The drilling cfforts for the geotechnical report were completed and thc borehole groutcd to avoid inadvertent dissemination of the petroleum products. I notified you of the situation on the afternoon of May 26, 1989. As we discussed, a representative of Earth Systems Environmental, Inc. can visit the site this week and prepare an estimate for a site assessment to aid in defining the degree and extcnt to which fuel products are prcscnt in the soil and groundwater.

SCOPE OF WORK This section describes the various tasks that will be performed to complete the investigation at the subject site. Task 1. Field Work This section summarizes the field method to be used during this phase of the work. Borehole Drilling. Brown and Caldwell (BC) will supervise the drilling-of 7 or 8 boreholes at the site. pro[osed borehole locations are'shown on Figure.l. ..Boreholes will be drilled using a rruck-mb""t.o -aririing rig_ equipped w.ith 8-inch-butside-diameter by 4-inch-inside- diameter hollow-sie-- uug"rr."

To date, the cuttings from the first two phases of investigationhave been stored on Unocal property in 55-gallon drums. The soil in the drums can nowbe segregated into unaffected soil and hydrocarbon-affected soil because the drums wereproperly labeled at the time of filling, and laboratory analyses have been received. According to the disposal plan, hydrocarbon-affected soil will be placed on and coveredwith plastic sheeting to prevent runoff should it rain. When approximately 15 cubic yardsof soil is stockpiled, it will be transported by a California-licensed hazardous waste haulerto a Class I landfill. This process will be repeated as necessary throughout theinvestigation. The current soil volume is approximately 8 cubic yards. The unaffected soilwould be spread out on the Unocal site. This plan has been verbally approved by Unocal,the San Luis Obispo County Health Department, and the California Regional Water QualityControl Board, Central Valley Region. Well Installation. A monitoring well will be installed in each borehole by inserting 2-inch-inside-diameter Schedule 4A polyvinyl chloride (PVC) casing with 15 feer of 0.020-inchmachine slotted well screen beneath the blank casing. The slotted casing will extend 10feet below the water table, in order to accommodate for seasonal fluctuations. Screw-onbottom caps will be installed at the bottom of each well. To gravel pack each rvell, coarse aquarium sand will be poured directly through the augeras the augers are being gradually removed from the borehole. The sand will extend - toapproximately 2 feet above the screen. A 2-foot bentonite pellet seal wilt be placedimmediately above the gravel pack and the augers will then be totally removed. - Theremaining annular space of each well will be filled with cement. Each well will becompleted with an abovegrade locking box. Typical monitoring well design is illusrrared onFigure 2. When the lead investigating agency deems monitoring groundwater quality is nolonger an issue, Unocal rvill be responsible for abandonment of the wells. Soil Samples. Three soil samples will be collected from each borehole. One sample will becollected at 1.5 feet, the second at midpoint between the surface and the water table, andthg third sample will be collected just above the water table. Soil samples will becollected using an l8-inch California modified drive sampler. Three, 2- by -6-inch brasstubes will be fitted into the drive sampler and driven inio undisturbed soil- to obtain thesoil sample. Sample tubes will then be removed from the sampler, the ends capped withfoil, plastic caps, and taped to provide an airtight seal. The soil samples will be-stored oni.: and protected from meltwater from the time of collection thiough delivery to thelaboratory. A continuous core will be collected, logged, and boxed on site for future study. TheUnified Soil Classification System will be used for logging the core. The core- will bescreened using ultraviolet light on site to detect hydrocarbons. This data will be recordedon the log. Monitoring Well Development. Following installation of each well, rhe well will bedeveloped by using a centrifugal pump or bailer until relatively sediment-free water isreceived. ,'t I T COMPLETED ABOVE GRADE IN LOCKABLE';' io 12' DTAMETER srEEL WELL covER PVC TOP PLUG GROUND SURFACE CONCRETE SEAL B' TO 12' DIAMETER AUGER HOLE 2I TO 4'FLUSH THREADED' SCHEDULE 40 PVC CAS(NG IW{TH PVC TOP CAP CEMENT/BENTO NITE G ROUT BENTON(T€ PELL€TS2 2' + 1I CLEAN IMPORTED SAND PACK' GRAIN SIZE VAATEELC DEPENDING ON SLOT SIZE OF CASING 2' TO 4' FLUSH.'THREADED, SCHEDULE 4O PVC icaeEru, o.o20-INCH slors oR LARGER OEPENOIt.{G ON FIELO CONDITIONS PVC BOTTOM PLUG 10'+ TO 20'1 NOT TO SCALE NOTE: ALL LENGTHS AND DEPTHS Y{BIABLE DEPENOING ON FIELD CONDITIONS Figure 2.

Inspection of Local Creeks. BC will _ visually inspect qortions of . San Luis Obispo and Duu"nport Creeks to obtain evidence of hydrocarbons. Evidence of hydrocarbon seepage will be recorded and mapped. Quality Assurance Plan The procedures of the qualiqy assurance plan for sample collection, identification, handling, and analysis are described below. Sampte Collection and Handling. Proper collection and handling are. essential to ensure the il"lrry oi the ru-pi". All sam"ples *ill be collected b-y. experi-enced. field personnel .usingsuitable containers 'which have been precleaned at the l-aboritory. The containers will be ;i;iy marked and dated for identification. All samples will be cooled and stored for analyiis no longer than the maximum allowable holding time. Sample ldentification and chain-of-custody-Procedures. The-se procedures ensure sample inieglrity and document sample possession 'from the time of collection to its ultimate Jirp"orui. Each sampie contaiher submitted for analysis will have a label affixed to identify th": j"b number, i"titpf"i, date of sample collection,. and a sample 1um!e1- unique to thatio*fif.. This informirion, in addition to . a description of the sample, field measurements,;;iii"g methodology, names of on-site personnel, and any other pertinent field obseivat'ions, will be rJCorded on the boring log or in the field records. A chain-of-cusrody card (Figure 3) will be used to record possession of the s-ample from time of collectioi io itr irival 'at the laboratory.

Downhole drilling "quip*"nt and the development pump witt Ue steam-cleaned before use in each borehole or monitoring well. Laboratory Analytical Quality Assurance In addition to routine calibration of the instruments with standards and blanks, the analystis required to run duplicate and spikes on 10 perc.urt of the. analyse-s to ensure an added *easu.e of precision and accuracy. Accuracy is also verified through the following: 1. Certification by DHS. 2. Participation in interlaboratory or round-robin programs. 3. "Blind" samples are submitted by the laboratory's_ quality assurance officer on a weekly basii. These are prepared from National Bureau of Standards or EPA reference standards. Safety Program It is important that the on-site safety program be designed to protect the worker from direct skin contact, inhalation, or ingestibn bf potentially hazardous materials that may be encounrered ar the site. It should -also familiarize the worker with appropriate first aid procedures in the event of a harmful exposure. . In order to do this, !h" potentially[ur-ao"i properties of petroleum hydrocarbbns and. their toxic effects have been reviewed by BC. fnii informarion was used to develop the following site safety plan for this work. Personnel Protection. This protection plan for this project is designed to prevent sampling personnel from exposure to pefrAleum hydrocarbons which might be encountered on site. The following clothing shall be worn by all on-site personnel: 1. Hard hat with optional face shield.2. Steel-toed boots.3. Gloves. To prevent direct skin contact, the following prote-ctive clothing will be personnel working on site and shall be worn if deemed necessary by hydrogeologist: 1. Breathable tyvek coveralls or cotton coveralls.2. Disposable vinyl gloves, changed between samp-lgs-3. Golgles to guarO against splash unless face shield is used. available forthe on-site 'Mr. July Larry Sdvaglio 7,1988 Page 8 No eating, drinking, or smoking will be allowed within 50 feet of the drilling and sampling operationi. No coniact lenses witl be worn by sampling personnel. First Aid. On-site personnel will be informed of the symptoms relaled- to exposure to rignifi.unt concentrations of perroleum products. {ppgdiagb _ symptoms include irritation ofrh; respiratory passages; headache; dizziness; lightheadedness; uncoordination; nausea; vomiting; und euentuiity unconsciousness. In the event that any on-l-{e_ personnel ".pr.iirii" iuch symptomi, operations will _be -stopq$. and medical attention will be obtainedi..fi;a;i"rv. ni riiu id"niiry tocal medical fiiitities before work begins, and a list of emergency numbers will be available during operations. First aid for exposure is as follows: Direct Contact Skin--Remove conraminated clothing immediately. Flush affected area immediately with ample amounts of water, then wash with soap and water. Eyes--Hold the eyelid open and flush with copious amounts of water. Inhalation Remove the victim to fresh air immediately; give artificial respiration as necessary. Line of Authority. The on-site BC hydrogeologist has on-site authority as t9 tu&ty "quip*"nt and pro'cedures employed, consiitent- witli this work plan and direction from the project manager. Emergency Services. The nearest emergency facility to the area where site work wilt be conducted is: Arroyo Grande Community Hospital 345 S.

It is our understanding that this contamination is not f romleakage of the pipe, and the source of the contamination is unknown at this time. Thissoil was transported to your site, at 276 Tank Farm Road, for temporary storage. On March 22, 1988, we held a joint meeting with yourself, Sorrel Davis fromRegional Water Quality Control, Randy Miller from our Department and myself. At thatmeeting I requested that your company continue to store the contaminated soil on yourproperty until the City of San Luis Obispo can determine the source and responsibleparty for the contamination. At that time I also agreed to allow your company toabandon in place 90 feet of the existing pipe line if UNOCAL agreed to the temporary storage of the contaminated soil. After the meeting, the City obtained permission fromthe San Luis Obispo County Department of Health Service to store the material at yourfacility. On March 24, UNOCAL agreed to this storage for a maximum of 90 days if the Cityof San Luis Obispo agrees to except lability for the storage and agrees to move thecontaminated soil within 90 days. You may consider this letter as a guarantee by the City of San Luis Obispo thatThe City will assume lability for the stored soil on your property and will remove thesoil by June 20, 1988, at the latest. If you have any questions concerning this agreement please call me at the above number. Very truly yours,t .- -z- n---.4, Erwin L.

At no time will the rinse be allowed to discharge onto the soil. Should the rinse be accidentally discharged the area will be treated as a contaminated site. Pipeline will be checked for lower explosive levels (LEL) prior to removal. This process will be obtained by the following: I 2. z.Injection of geothermal water through the pipeline at l80o F orgreater (twice). -o R- b Introduction of surfactants of low phosphates and is bio-degradableinto 100'sections of pipe and collected. NOTE: Collection of rinse will be by vacuum or suction truck. 3 During removal UNOCAL will indicate that no significant spillage or leakage has occurred the following will be provided by the responsible party: Independent State Geologist. Field hydrocarbon vapor test (FHV) - Acceptable equipment to measure ambient head space would be H-NU model l0l or Organic Vapor Analyzer (OVA). The OVA or H-NU will provide a quick base test for on site assessment. In order to eliminate confusion as to what is contaminated soil or not, TPH must show <100 PPM through ambient head space by field tests. Should contamination exist the following process will be adhered to: Lab analysis - 3050, 62518270, and TPH - Lab analysis - random sample will be drawn to show no contaminants are present. Acceptable EPA methods are 3050 metals,625l8270 semi volatile organics, acids and Total Petroleum Hydrocarbons (TPH). 2. Samples will be drawn to show aerial and vertical extent of contamination. Borings will be at least 20'depth or to ground water. A 24 hour turn around will only be accepted for analysis, project could be stopped until analysis is achieved if longer than 24 hours. Soil removal will be the only allowable method of remediation. Soil will be manifested to a TSD Facility or to a DOHS approved land farm for fu rther assessment/ remediation. Contaminated sites will be identified and protected from public harm while awaiting lab analysis. Work may continue only if proper cleaning of exposed equipment takes place.

INTRODUCTION The essential facts in t.his case are uncontroverted. In 194I the defendant, City of Santa Monica, negotiated and signed a forty year nchise a reement with the plaintiff, ShelI Oi1 Co.1 Pursuant to the franchise, Shelt installed and operated a pipeLine 10 inches in diamet.er and 3.9 miles in length beneaL.h public city streets. This segment is part of an 82.2 mile pipelrne used by ShelI to transport cruoe oiI from Ventura County Lo its Wilmington refinery in Los Angeles County. In 1981 the franchise came up fOr renewal and santa i4onica ooosed two changes in the terms of the agreement: first py Ptys cl Notice Piys 1 JS.6 JUN 15 1986 t 1 2 3 I 4 5 6 7 8 I 10 11 t2 13 t4 15 16 t7 18 19 20 2T .> c) 23 24 25 26 otzt 28 ll a rent increase from $1,000 per mile to $591000 per mile and, secondly, incorporation of seven pages of detailed safety standards regulating the pipeline. Shell brought this action seeking, inter alia, a declaration (1) that the commerce clause of the federal constitution, as well as a similar california constitutional provision, Iimit the franchise fee payable to Santa l"lonica to an amount no greater than the value of actual services or benefits provided by the City.; and (2) that any and all franchise terms regulating safety are preempted by federal law. In their cross motions for summary judgment, now under submission, both parties agree that this case, in its present posture, pf€sents, for the most part, pure issues of law. II. FRANCHISE FEE A. FEDERAL tAW The Commerce Clause, U.S. Const. Art' I S I cI" 3' prevents a State from taking any action which impedes the free ftow of trade between states, Freeman v. Hewit ' 329 u. S. 249 , 252, 67 S.Ct. 2'74 | 2'76 | 91 L.Ed. 265 (1946). Howeverr &D exception exists where the State or its political subdivis'ion acts as a market ParticiPant.Reeves I nc. v.

The gity asserts that rather than regulating firms' private commercial dealings, it participates in 2 '|1 2 'J 4 5 6 7 8 I 10 11 L2 13 t4 15 16 L7 18 19 20 2l q, oo/. t) 24 25 26 qnL' 2B a market Lransaction with a freely contracting private corporat.ion. santa Monica cites White v. l'lassachusetts Counc i I of Construction Employers 'Inc. ' 460 U.S. 204 (1983) ' which held municipal contracting to be a form of market participation' SheII relies almost exclusively on Western OiI & Gas Assr n v. C 726 F.2d 1340 (9th Cir. 1984)'aff'd bv an eou a 1lvorv di vided court, 47L U.S., 85 L.Ed.2d 6I (1985) (."Corv"), a case involving very similar facts. cory held that state-owned monopolies were outside the scope of the market participant doctrine. In cory, the state of california claimed to be a market participant in its dealings with several oi1 companies' The Ninth Circuit, however, held that a State is not protected by the market participant doctrine where it holds a "complete monopoly" over the relevant market' The oil companies in cory owned and operated offshore drilling rigs and were unable to transport crude oi1 onshore without pass ing over tidal..and submerged lands owned by the State of CaI if ornia. Under the terms of their }e'aSes, the companies paid to california a flat annual "rent" in the amount of six percent of the appraised value of the land over which the oil passed. In Ig76 California amended the rental regulations so as to: (1) increase the six percent charge to eight percenti and, (2\ impose a "volumetric throughput" charge which would vary the rent in direct proportion to the gallonage being piped' The court in Corv struck down the latter portion of the chall.enged regulations as violative of the commerce clause. Corv hetd, first, that California could not invoke the market participant doctrine because it held a monopoly over 3 I tlt rl 'll :ll"ll 4ll ,li 6 7 I o 10 11 L2 13 14 1<iU 16 T7 18 10 20 2T ,9 23 24 or/-.) 26 27 2B coastal access and, secondly, that'bhe commerce cl-ause prohibits a volumetric throughput charge by which rent for the leasing of state-owned tidelands varies with the gallonage of oil shipped in interstate commerce. sheIl contends that, under corv, first, Santa Monica holds a monopoly which prevents it fr:om invoking the market participant doctrine, and, secondly, the per-mi1e franchise fee exhibits the same consCiCutional de€ects as the per-gaIlon throughput, charge. As discuss.ed below in parts I' lrr and ,tZ, respectively, neither of these contentions has merit. 1. MonoPolY InCo::vrtherewa:nopracticalwayfortheplaintiff oi-1 companies to transport oil from their refineries without traversing the tidal and submerged lanos owned by the defendants- state of california. Due to the physical and practical inmobility of the plaintiffs' offshore processing pLanLs' combined with the calif ornia stand Lands commiss j.onrs o'complet'e monopoly" over coastal acceSS ' the oiI companies in CorV h'ere unable to go to any other competitors for Lhe required strip of shoreline. They could not "shop around" but had to renew their Ieases on whatever terms the state demanded. For these re'asons' the court in Cory held California was a monopolistr Isther t'han a competitor, in the relevant market, and for tha! reason' the mbrket parti.cipant doctrine did not apply' ,, ' shelI argues Lhat it Cann.ot "shop aroundr" but nlust deal with the city and, therefore, the corv, stale-owned monopoly exception to the market participant doctrine applies' Santa l"lonica responds that more is required to prove "monopoly" than a A.+ t rl.l!

The city controLs a four mile strip as compared to the State control, in Corv, of hundreds of miles of coastline. Moreover, the strip in issue here, unlike the California coasttine, has no "strategic geographic" significance, 725 F'2d at 1345. Shel1's right of way does not run east/west from Santa Moni-ca beach inland; rather it runs north,/sout'h, parallel to' and only a few blocks from, the city's eastern boundaryo The oil producers in Corv faced California-owned tidal and submerged lands no matter where they looked for coastal access. fn this CaSe, by conLrast, Santa Monica has shown -- : and, in fact, Shell has concededz -- the existence of a number of alternative means of transporting oil to its Wilmington refinery. SheII could obtain rights of way from private or other municipal Iandowners; it could negotiate exchange agreements with owners of other private pipelinesr of it. could use tank trucks or barges. shell could also pay to use common carrier pipelines which, under Ca1. Pub. Util, Code S 6]5, have power of eminent domain. In connection with this option, the City argues that shell is seeking the best of both worlds. If sheIl prevails, and santa Monica must renew for no more than the actual value of benefits or services the City provides, ShelI wiIl enjoy benefits of eminent domain without the concomiLant rate and regulatory restrictions imposed on common carrier pipeli.nes' Over the forty year franchise period just expired, the volume of oiI increased t.hirty percent and its value rose sharply; yet Shell was imrnune from increases in the fr:anchise fee because the 5 t 1 2 3 4 Ci.ty was bound to honor the contract.. Having enjoyed the benefit of its bargain, SheII now claims the franchise is not a contract at. alI but, rather, a "user" f ee , and hence that , under Co::V, the united states constitution controls the price term santa Monica makes the point that no one but the franchisor ever has power to renew a fr:anchise; by definition, Do franchisee can ever "shop around" for renewal. Only in a trivial sense may the term "monopoly" be applied to a franchisor by virtue of the fact it is thq lone "seIIer'i of renewal rights' The Same reasoning applies to grantors of easements. Because land is unique, the grantee can never "shop arourid" for renewal : of an easement. And even i.f the term "monopolist" is applied to Santa i"lonica in its role as franchisor or grantor, it stiIl does not follow that the City could command monopoly profits because here, !t j.s dealing with a monopsonist. shell is the only potential "bUyer" of this particular,.eaSement, or franchise because it is Connected at both ends to-its existing pipeline. shelI argues that santa l'{onica enjoys tremendous Ieverage because the seventy eight miles of remaining pipeline are dependant on this four mile segment. Bargaining leverage does not, however, define monopoly. Rather, it tends to be a usual result of monopoly power. The four mile strip in this case could have been laid a few blocks east of its present location, avoiging Santa I,lonica altogether.

The thresholdquestions whether a State enjoys a "monopoly"position . would require complex factualinquiries about such issues as elasticity ofdemand for other alternative sources of supply. Commonwealth Edison Co. v. Montana , 453 U. S . 601 , 6 19-600 n'8 , 10I S.Ct . 2945, 2954-55 (f981) ('Montana") . As a matter of economics, semantics or antitrust principles,.there may be room for disagreement over whether Santa Monica should be labeled a monopolist. However the issue cannot' be decided by labels. Cory was marked by California's control, from Mexico to Oregon, of this country's western shore. In contrast, Santa l4onicars controi over a f our mile inland strip shcws that the City possesses no geographic dominance comparable to that found in Corv shelI's remaining argument for application of the State-owned monopoly exception to the market participant doctrine rests on the lack of renewal fee restr:ictions in the provisions of the original franchise agreement. The City is free to apply great Ieverage in negotiating renewal. However, the definition of monopoly for purposes of deciding constitutional claims ought not depend on the terms of a contract. As the court staLed in I,lontana: " 1t would be strange indeed if the legality of - a tax could be made to depend on the vagaries of the terms of contracts." Id. quoting the State court in Montana, 6I5 P.2d B1'7 | 856 (f980). The same principle applies here.3 Shell28 7 .l 1 2 3 d 5 6 I 8 I 10 11 L2 13 l4 15 16 l7 18 19 20 21 qq noLO 61L+ 25 26 on/,t 28 maintains that t.he terms of the agreement leave the franchisee open to exploiLation. However, in arms Iength negotiation between parLies of equal bargaining power, such a concessicn is presumably cornpensated for by other valuable consideration when the franchise is first negotiatecl. In Sum, the "complete monopoly" enjoyed by California in cgv rested on its strategic geographic dominance over relevant portions of the western shoreline of the .continental United States. Here, the Cit.y does not possess any similar market oorninance. Therefore, the Cory State-owned monopoly exception to the market participant doctine does not app1y, and Santa l"lonica ' is not prohibited f rom ciiaroing market value' 2, Rent vs. User Fee Even aSsuming Cory controls and the market participant Ooctrine does not apply, the f ee in this case " is not graduaterC by the amount of the business, nor . fixec for the privilege of doing business." corv | 726 F.2C at L344 ' quoting St. Lou i.s v . tJestern union Tel. co., 148 u.S. 92, 97, 13 S.Ct. 485, 487 (1893). Thus, the fee does not exhibit the unconstitutional defects found in the volumetric charge struck down in cory. InStead, the flat franchise fee resembles the percent-of- appraised-va1ue portion of the regulations challenged in Cory' This.pari of the regulation, quoted and explained, bu.t not invalidated by Cory, imposed a flat charge of six percen! of appraisal value as rent for the right of way, In 1976 when the j.volumetric surcharge \,JaS added, the f lat rate was also increased to eight percent. In part "b" of the corv opinion, the court rl ;ll 'll4ll il5ll 6 7 8 I 10 11 t2 13 74 15 16 T7 18 19 2A 2t 22 ooLO 24 otrlJ t) 26 27 28 struck down cnly the volumetric charge which had been designed and defended aS a user fee. According to CorV, Montana, $Prg, forbids user charges, such as a gallonage charge, which bear no relation to actual use. Cory cited Montana for the.proposition that "these 'uSer.' charges cannot be disproportionate tc the benefits conferred by the State." Neither the challenged franchise fee in this case, nor the six percent (Iater, eight percent) flat fee in Cory, is forbidden by Montana.4 In the portion of Montana relied on by both She1l in this case, and by the court in Cory, the Supreme Court discussed charges which are designed and defended as user fees, and noted Ehat Commerce Clause cases have required such charges to be calculated by a formula which measures actual use. Setting that portion of ir{ontana in its proper context, it becomes apparent although Cory did not reach the issue that six percent and eight percent charges were constitutionally permissible under Montana without any showing that they were equal Lo the value of State provided services or benefits In l'Iontana, coal producers challenged a severance tax as clearly repugnant to the principles underlying the Commerce Clause. There was evidence showing the severance "tax" had been designed to manipulate "tax escatation" clauses in existing long termsupp1ycontractSbetweenMontanaproducersandmidwest coal-burning power plants which were dependant on low-sulphur i4ont.ana coa1. 453 U.S. 64I n.6 (BIackmun, J. dissenting)..

Id. (qu'oting Towe,Explana t ions of Reasons for Montana coal Tax, at 4). Numerous facts in Montana bear out the charge that the State pursued a deliberate and sophistj-cated "policy of 'oPEc-like revenue maximizaLidn.'" Id. at 643, quoting R.

The State of Montana also held a. st.rategic geographic position and could well be.considered a "monopolist," depending on the definition of the relevant market. Montana contained roughly ?0 percent of aII known reserves oE low-sulphur coal ' ' Id . at 638 n. I. Also, in Montana, there was no correlation between the severance tax and the services or benef its conf erred by t'he State. plaintiffs had offered to prove the challenged tax of Sz per ton exacLed more than 100 times the maximum amount of ',legitimate loial impact costs." Id. at 62L n.10. Notwiths tand ing all of t,he above , the supreme court upheld the severance charge, emphasizing that it was "computed at the same rate regardless of the final destination of the coal." Id. at 6IB.

See alSO id. at 628: "under our federal system, the determination is to be made by state legislatures in the first instance and, if necessaE!r by Congress when particular state taxes are thought Lo be contrary to federal interestS. " Thus, I"lontana tends to bear out Santa Monica's objection that more is required to prove a State-imposed burden on commerce is unconstitutional than to describe it as "undue" oi " burdensome.

The generalized sense Lhat a St:'ate- imposed levy implicates Commerce CIause concerns is no! a sufficient basis for holding the fee unconstitutional. See Montana' 453 U, S. at 628.

The gallonage charge in Corv was one such fee. The six percent 1:d eight percent flat fees in Corv, by contrastr 'were not designed to meter "use"' Hence the court in Corv did not require' and California did not produce, €Vidence that six percent or eight percent -- as opposed to tv,ro percent or ten percent -- equalled the value of benef its or services provided by the sLate to the oil companies' TheCityarguesthatthefranchisefeeinthiscase bears no resemblance to tlie classic "user fee" situation arising when an item.ci commerce merely passes through the jurisdiction of the taxing bodY.

SheIl's pipeline physically and permanently occupies space in the rtionate to theClark v. Paul Gra S. Ct. at 3. 28 T?. 1 subsurface of the CitYrs streets. Santa l'lonica goes on to point out that it negotiates many leases of City-owned facilities including, for examPIe, space at the Santa Monica Pier and Santa Monica Airport. In these settings, oo one.has ever challenged a City's right to obtain market rent. At bottom, Santa Monica relies on the distinction between charges levied directly on persons or goods naking use of State provided facilities to move in the stream of interstate : commerce (e.g. petroleum gallonage, airplane passengers' highway vehicles or.conmercial vessels) as opposed to charges negotiated in exchange tor physical possession of State owned properby i granted exclusively to one pri.vate party. The per mile charge in this case is distinguishable, on that basis, from the volumetric throughput charge struck down in Cory. Whil.e Santa i'lonica's franchise fee is somewhat analogous to lhe six percent ano eight percent flat raLes ln cory, the court did not find Lhem objectionable. Thus, Santa I'lonicars f ranchise fee survives Commerce Clause scrulinY. B.

In Los Anoeles I the court expanded upon Belridqe , nolinQ that the focus of inquiry is into the sole issue of apportion- ment.

The question whether the PrinciP Ies of Los Anqeles should be expanded to forbid the $59 r000/mile fee is a novel question of state }aw. santa Monica distinguishes the fee as a negotiated contract term, not a tax. However, just as the California Supreme Court has struck down taxes other tiran the particular "gross r€ceipLs tax" invalidated in LOg A no e les the court could also strike down non-tax. ciiarges such as Iicense or franchise fees if they exhibit either (a) intercity discrimination or (b) extraterritorial effect. As matters now stand, the $59,000/mile fee could be seen to exhibit these infirmities. Under the guise of simply extracting market value for a right, of wa!r Santa.l"lonica may be using as leverage the ?8 miles of pipeline lying beyond the fcur mile segment under Santa I'lonica streets. However, aS matters stood in 1941, Santa Monica had no such leverage. No pipe was yet laid. It \{as SheII who could negotiate among cities for the most advantageous terrns. It may 15 'il2ti ,ll ,ll 'li be.Lhrat the nub of this cas.e is whe't.her to view the part'ies' rights as matter now stand .- with Shell having invested a tremendous value in the pipeline or circa 1941 when SheII voluntarily submitted to a forty year arrangelnant with no contractual proLeclions for either party upon expiration' Viewed aS of the time the f ranchise was negot'iated, Santa t4onica asserts it was acting in a proprietary, not sovereign, capacity: "A franchise or Iicense may be the product of either governmental or p.rivate action." PeoPIe ex re1. F Iou rne v. Y ellow Cab Company ,30 CaI.App.3d 4!, 106 Cal.RPtr. g74, B?B (1973), If SheII were to sign a contract allowing it to drill under a private Ian'iownerr s ground f or f orty years, that owner would be free to confiscate the remaining oil when the f ranchise expired. For Shell to persuasively contend that the Cal-ifornia Supreme Cour! would expa ndL os Anoe les to inval iciate this f ee , i t lmust address tie following line of reailoning suggested by Santa lqonica: Under the Catif ornia constitution, if the pipeline weren't already in place and. ShelI approached Santa l"lonica with an iniLial proposition to Iay it, Santa Monica could refuse to agree to grant any right-of-way. Santa Monica should now 'possess the lesser included power to simply refuse to renewr r€9ardless of pr j,ce r log ically, then, the right to charge a high price f oI Io.w a fortior'i from the right to refuse to deal'SheII, fails to deal butto refute that Santa Monica cou Id initiallv refuse argues Santa Monica cannot refuse now because Lhe line is already {in the ground. Hence, Shell is necessariiy demanding more than ie bargained for.

In sum, the time for a franchisee to consider the renewal probl-em is when il initially negotiates for the f ranchise. These considerations, SanLa l'lonica concludes, would counsel against expansion of the holding of Los Angeles. In 1941, Santa Monica could not have Ou*unO"O an excessive fee based on leverage arising from its strategic position in relation to extraterritorial segments of the pipeline. Tf SheII f inds itself in a worse position now' it' is only because of decisions it freely made to sign a contracL and tay a pipeline. SheII has never addressed the point that its negoCiating disadvantager ds connected to the extraterritorial considerations, is self-imPosed. Additionally' the Lhrust of distinguished as soleIy coqcerning the method Af assessing taxes and nowhere addressing the rate of tax. A fairly apportioned tax may be high so long as it is not confiscatory. See Qeneral Motors Corp. v. City of Los Anqeles, 5 CaI'3d 229 | n.17 , 95 Cal,R.ptr, 635, 644 n.I? (f97I) . Santa Monica's method of assessing Lhis "tax" is to negotiate the market value of the easement. Shell nowhere alleges thaL $59 ,000,/mile, is conf iscatory. Besides, the right of way belongs to Santa iulonica; it cannot confiscate what it already owns.LOS AN eles .neither forbids excessive taxes nor teaches how to define "excessive"' Los Anqeles is nowhere concerned with high'au*"", only with discriminatory or extraterritorial taxes.

The Act def ines pipelines "in' interstate Or fOreign Cqmmerce" aS "interStater" and all other pipelines subject to the Act, namely those "af'fecting" interstate commerce, ds " intrastate. " santa Monica does not dispute that the Act preempLs safety regulation of interstate pipelines. However, the City contends that She1l's pipeline is intrastate. This contention.. creates disputes of fact centered around application of the "shipper's intent" test. See Burling ton Northern v. w erhauser t 719 F.2d 304 (9cfr Cir. ]983). As the'record now stands, the interstate or intrastate characLer of the pipeline under the HLPSA cannot be determined. Therefore, it must be assumed, fot purposes of ruling on SheII's motion for summary judgment, that this is an intrastate PipeIine. The HLPSA gives the secretary of Transportation authority to establish safety standards for interstate and intrastat.e pipelines. The..Secretary ma!r however, delegate Eo a "State agency" jurisdicLion to prescribe safety standards for intrastate pipelines. That StaLe agency must submit to the Secretary an annual certification showing that it has regulatory jurisdiction, that it has adopted each minimum federa] safety standard, that it is enforcing each such standard, that it is encouraging programs designed to prevent pipeline damage, and that it has authority to require certain record maintenance reporting and inspection, The term "state agency" is not speqia)-ly defined in the Actr but iLs use in Lhe Act clearly is limited to those State agencies to which regulatory authority has been delegated. 19 .t The federal act specif ical'11' provides Lhat no state agenc), may impose any safety standards on interstate pipelines, but a State agency may adopt additional or more stringent safety siandards for intrastate pipeline facilities. 49 U.S.C. S 2002(d). No State or municipal body may adopt or conLinue to enforce any safeby regulation applicable to piPelines which affect interstate commerce unless it is a State agency to which regulatory authority has been delegated by the Secretary of Transporiat ion. The California }egislature has determined that the State Fire Marshal is the State agency exercising the safety regulatory authority under the Feder-e'!. hazardous Liquid Pipeline Safety AcE. CaI. Gov. Code S 51010. On or about October 2I,1985, the State Fire i4arshal obtained his certification from the Secretary of Transpcrtation. The City of Santa Monica has not been so certified and so has no jurisdicLion to regulate pipeline safety. In u i"lateC development, the6alifornia At,torney General recently issued an opinion to the office of the state Fire iviarshal. That opinion r. issued January I , 19 86 , concludes that a local government agency does not have power to impose safety regulations on an "intrastate" pipeline as that terrn is defined in the Federal Hazardous Liquid Pipeline safety Act. That opinion appenos an opinion from the u.s. Department of Transportation to the City of Long Beach, Cdlifornia' .indicat'ing :that the Department of Transportation takes the same view as the Attorney General.

The monitoring schedule was changed to a semi- annual basis in March lgg2, in accordance with the California Regional Water Quality Control Board's Monitoring and 1992. This report describes the site for 1993. Reporting Program No. 92-42, dated February 10, first semiannual monitoring event conducted at the Groundwater elevations measured in March 1993 have risen from 0'80 since last being measured in September 1992. The groundwater level attributed to normal seasonal fluctuations' to 9.59 feet increases are The current groundwater flow direction calculated from the wells is to the southwest' The calculated groundwater gradient beneath the site in March L993 averages 0'065 feet per foot. Total petroleum hydrocarbons, benzene, toluene, ethyl benzene and xylenes and polynuclear aromatic hydrocarbons were not detected in any of the five monitoring wells. TPH concentrations in well Mw-l have decreased from 360 tlgll to less than detectable levels since September 1992' Crude oil has apparently not migrated laterally from the pipeline alignment' as it was not detected in any of the monitoring wells. Crude oil has not been detected in any of the wells since a trace of oil was detected in MW-5 in July 1991' Unocal-Pismo/Beach Streets ,)April 20, 1993 2.0 INTRODUCTION This report presents the results of ESE's March 1993 monitoring of five groundwater monitoring wells located on Pismo and Beach Streets in San Luis Obispo, California. The monitoring was performed to comply with the California Regional Water Quality Control Board (CRWQCB) Monitoring and Reporting Program No. 92-42, which requires semiannual monitoring of the well array. Figure 1 is a vicinity map showing the general location of the site, and Figure 2 is a site map showing the locations of the five groundwater monitoring wells (Figures and Tables are located at the end of the text). Also included in monitoring events, this report are groundwater monitoring data from three prior conducted in November l99l and March/September 1992' I ) 3.0 PROJECT BACKGROUND During replacement of portions of two 8-inch diameter product pipelines in August 1989, soils apparently containing petroleum hydrocarbons were encountered in trenches for the new pipelines near the intersection of Pismo and Beach Streets. Subsequent site assessments indicated that soil and groundwater beneath this atea had been impacted by crude oil. Unocal Corporation performed two quarters of monitoring on a voluntary basis in July and November 1991, with the results being transmitted to the CRWeCB. The site is currently on a semiannual monitoring program to evaluate whether hydrocarbons are migrating in groundwater. Well MW-4 was destroyed in accordance with State and local regulations in April 1992, due to concerns that its screened interval may have been linking two hydrologically separate water-bearing zones. 4.0 PURPOSE AND SCOPE The purpose of this monitoring program is to evaluate the thickness and potential migration of immiscible hydrocarbons (crude oil), if present, and to identify the ES -0907- l 9203-2021.RPT I l Unocal-Pismo/Beach Streets April 20, 1993 presence of dissotved hydrocarbon compounds in groundwater, associated with the former pipeline leak. The scope of work performed included the following: 3 a a a a Preparation of a Site Health & Safety Plan and Traffic Safety Plan' Groundwater gauging, flow direction and hydraulic gradient determination Purging and sampling of five groundwater monitoring wells. Laboratory analysis of five groundwater samples' Preparation of this report presenting the data, conclusions and recommendations regarding the monitoring. GROUNDWATER GAUGING, FLOW DIRECTION AND GRADIENT DETERMINATION a 5.0 ) Groundwater was present in the wells at depths ranging from 9'65 (MW-5) to 27 '15 (MW-6) feet below grade. These elevations are 0.80 to 9.59 feet higher than those measured in September 1992. The groundwater flow direction beneath the site was calculated to be to the southwest, at a gradient of 0.065. Wellhead elevation data presented in this report were obtained from a survey performed in January l99l by Groundwater Technology, Inc. (GTI). Table 1 presents a summary of groundwater elevations as determined from the March 1993 groundwater monitoring program performed by ESE. Table 2 presents wellhead and groundwater elevations from the November lggl and March/September 1992 monitoring events, and the current monitoring event. Figure 3 presents the groundwater elevation contour map calculated from the September lgg} data, with groundwater elevations listed next to the corresponding monitoring well. Appendix A (Standard Operating Procedures) presents the methods for obtaining the groundwater depth measurements. 6.0 CRUDE OIL THICKNESS ESTIMATION Crude oil was not detected in any of the five monitoring wells during the March 1993 monitoring ovent. Table 3 presents a summary of crude oil thicknesses measured in the three previous monitoring events. None of the remaining monitoring wells have contained crude oil since monitoring of the site began in 1991. MW-5 last contained a ES -0907- I 9203-202l.RPT Unocal-Pismo/Beach Streets April 20, 1993 trace of crude oil (less than 0.01 feet) in July 1991, and MW-4 last contained a trace in November 1991. These wells have not been found to contain oil since that time. 7.0 PURGING AND GROUNDWATER SAMPLING Purging and sampling of the five groundwater monitoring wells was conducted on March 15, 1993. Appendix A presents groundwater sampling protocol for this project. Water produced by well purging was contained in 55-gallon DOT-approved drums and transported to the Unocal tank farm on Tank Farm Road. 8.O ANALYTICAL METHODS The March 1993 groundwater monitoring program included the following: ANALYTICAL METHODS FOR MARCH 1993 MONITORING Monitoring Well Iden ti fic ati on TPHIBTE&X-EPA Test Method 8260* Polynuclear AromaticsEPA Test Method 610 MW-1 X X MW-2 X X MW-3 X X MW-5 X X MW-6 X X* using cryogenic focusing Appendix B contains laboratory reports and chain-of-custody sheets for the March L993 analyses. 4 _l ES -0907- 1 9203-202l.RPT Unocal-Pismo/Beach Streets 5 April 20, 1993 'l I ) 9.0 DISCUSSION OF ANALYTICAL RESULTS 9.1 Total Petroleum Hydrocarbons (TPH) TPH was not detected in any of the monitoring wells, with a detection limit of 50 t g/t.

TPH, BTE&X and PNAs were not detected in any of the five monitoring wells. TPH had been detected at a concentration of 360 ttgll in well MW-l in September 1992; the TPH concentration has decreased to below detectable Ievels in March 1993. . Crude oil was not observed in any of the five wells during the current monitoring event. Traces of crude oil were detected in MW-4 in the July and November 1991 monitoring events, and in MW-5 during the July 1991 monitoring event. Well MW-4 was destroyed in accordance with State and local requirements in April 1992. Crude oil has not been observed in any of the wells since November 1991. . Groundwater levels have risen in all wells since they were last measured in September 1992. The higher groundwater levels are consistent with normal seasonal fluctuations that have been observed at this and other monitoring sites over the past three years. - . The groundwater flow direction was calculated to be southwest, and is relatively consistent throughout the site. The flow direction observed during the current monitoring period towards the southwesterly is consistent ES -0907 - 1 9203-202r.RPT U ismo/Beach Streets April 20, 1993 with flow directions determined in earlier investigations. The groundwater gradient is relatively steep, averaging 0.065. 1 1.0 LIMITATION This report has been prepared for the exclusive use of the unocal corporation as it pertains to the pipeline site located at the intersection of Pismo and Beach Streets in San Luis Obispo, California.

Depths were measured to an accuracy of 0.01 feet from a designated point on the top of each well casing. Prior to use at each monitoring well, the water sensing probe and a portion of the measuring tape was washed with TSPrM (tri-sodium phosphate), rinsed with clean tap water and deioni zed water, then allowed to air dry to reduce the possibility of cross-contamination. The water level probe was lowered until the top of the water surface within the monitoring well was detected. once the water surface was detected, a continuous signal from the meter sounded' The depth to water measurement was performed at least three times for each monitoring well to verify the initial measurement obtained. A final depth to water measuremsnt was recorded on a standard form. I -t _t J J GROUNDWATER SAMPLING PROTOCOL Purging and sampling equipment was disassembled and washed with a non- phosphate detergent solution, rinsed with tap water and deionized water, then allowed to air dry before purging and sampling each well, to reduce the possibility of cross-contamination. Prior to sampling, the groundwater monitoring wells were purged with a pre-cleaned bailer to remove stagnant water in the wells. During purging, key parameters including temperature, conductivity, and pH were measured with a portable electronic meter and noted. The meter was calibrated prior to the sampling event. Purging continued until the key parameters stabilized. Approximately three to four well casing volumes of groundwater were removed (approximately 2 to 6 gallons). The groundwater monitoring wells were sampled after water in the wells had recharged to approximately SOVo of the original groundwater elevation. If during purging, the monitoring well was purged dry, purging was stopped for approximately five minutes to allow the well to recharge. tf the well did not recharge at a sufficient rate to continue purging the three to four casing volumes, the well was purged dry two times and allowed to recharge until sampl ing. Following purging, groundwater samples were collected with pre-cleaned TeflonrM bailers, and discharged with a non-aerating bottom emptying device into sterilized glass containers, capped with TeflonrM septa, labeled, and chilled in an ice chest for transport to a State of California Department of Health Services (DOHS) laboratory certified for the analyses requested. Water samples were handled and transported according to the Environmental Protection Agency (EPA) protocol. Sample identification and chain of custody procedures were utilized for the samples to ensure sample integrity and to document sample possession from the time of collection to its ultimate destination. The sample labels identify the job number, sampler, date and time of collection and sample number unique to the sample.

Groundwater monitoring has been conducted at the San Luis Drive site since January 1990. The groundwater flow direction calculated during March 1993 was similar to the December 1992 flow direction, and indicated an overall flow approximately 10 degrees west of south. The groundwater gradient beneath the site was calculated to be 0.007 during December, essentially the same as the previous quarter. Groundwater elevations beneath the site have risen an average of 9.3 feet since December 1992. Groundwater depths range from 20.14 feet to 23.55 feet below the ground surface. Benzene, toluene, ethylbenzene, or xylenes were not detected in water samples collected from the six monitoring wells sampled this quarter, nor were they detected in the water sample recovered from the School Well located on the San Luis Obispo High School property. Less than 0.01 feet of crude oil was detected in well MW-2 during March 1993 monitoring. This represents a decrease in product thickness since December 1992, when a 1.92-foot thickness of crude oil was measured- A hydrocarbon sheen was observed on the surface of purge water collected from monitoring wells MW-3 and MW-10; consequently, these wells were not sampled for analysis. Traces of crude oil have been observed in these wells during the four previous monitoring events. We do not believe that lateral migration of crude oil in groundwater is indicated by the March 1993 data. lll Unocal, San Luis Drive 1 April 20, 1993 1.0 INTRODUCTION This report presents first quarter 1993 monitoring results of Unocal's ten groundwater moniroring wells (MW-l through MW-10) and the idle San Luis Coastal Unified School District proposed supply well (School Well), located on San Luis Drive in San Luis Obispo, California. Figure I is a vicinity map presenting the location of the site, and Figure 2 is a site map presenting tho locations of the ten wells (Figures and Tables are located at the end of the text). Also shown on Figure 2 is the location of the School Well, which is located approximately 300 feet southeast of the former pipeline leak area. The School Well is not currently used as a water source, and does not have a pump or piping installed. Data from the three previous monitoring events in May, August and December 1992 are included with the March 1993 data at the end of the text. 2.0 PURPOSE AND SCOPE The purpose of this monitoring program is to evaluate the potential for migration of crude oil and dissolved petroleum hydrocarbons in groundwater, associated with a former crude oil pipeline leak. The scope of work performed includes the following: Preparation of a Site Safety Plan and a Traffic Safety Plan. Groundwater gauging, contouring, and flow direction determination Purging and sampling of six groundwater monitoring wells, and the School Well. Laboratory analysis of seven groundwater samples 3.0 GROUNDWATER GAUGING AND FLOW DIRECTION DETERMINATION Groundwater depths beneath the ground surface range from 20.14 feet in well MW-6, to 23.55 feet in the School Well, as measured on March 1, 1993. Groundwater levels have risen an average of 9.3 feet since November 1992. The groundwater flow ES -0903- I 9304-2001.RPT Unocal, San Luis Drive April 20, 1993 direction beneath the site is toward the south-southwest, at an average gradient of 0.007. Wellhead elevation data presented in this report are from a survey performed in December 1990, and are relative to a United States Geologic Survey benchmark. Table 1 presents a summary of groundwater elevations as determined from the March Lgg3 groundwater monitoring program. Table 2 presents a comparison of groundwater elevations from May, August and December 1992, and March 1993. Figure 3 presents a groundwater elevation contour map calculated from the March lgg3 data. Groundwater elevations are listed adjacent to each monitoring well' Appendix A (Standard Operating Procedures) presents the methods used for obtaining the groundwater depth measurements. 4 . O CRUDE OIL THICKNESS ESTIMATION Crude oil was observed only in monitoring well MW-2 during the March 1993 monitoring period. A trace of crude oil (less than 0.01 feet thick) was observed in well MW-2, representing a decrease of 1.92 feet since December 1992, when 1.92 feet of crude oil was measured. The decrease of oil in the well may be related to the rising water levels in the monitoring area, as the same phenomenon was observed in February lgg2, during a period of high groundwater levels following seasonal rains. The mechanism for the decreasing oil thickness is unclear, however. Table 3 presents summaries of the current and three previous crude oil thickness measurements. Appendix A (Standard Operating Procedures) presents methods used for obtaining crude oil thickness measurements. 5.0 PURGING AND GROUNDWATER SAMPLING Purging of nine of the ten groundwater monitoring wells and the School Well was conducted on March 1, 1993. Sampling of six of the ten monitoring wells and the School Well was also conducted on March l. Monitoring well MW-2 contained a trace of visible crude oil, and was therefore not sampled. A sheen of oil was visible in purge water from wells MW-3 and MW-10; therefore, these wells were not sampled. 2 I J l I ES-0903- I 9304-2001.RPT Unocal, San Luis Drive April 20, 1993 Each of these wells has contained visible traces of hydrocarbons in purge water in the four most recent monitoring events. Appendix A presents the groundwater sampling protocol for this project. Water produced by well purging was contained in DOT approved 55-gallon drums and transported to the Unocal tank farm on Tank Farm Road. 6.0 ANALYTICAL METHODS Analytical methods employed during the March 1993 groundwater monitoring program are summarized in the following table: ANALYTICAL METHODS EMPLO YED DURING MARCH 1993 Appendix B contains laboratory reports, QA/QC documents and chain-of-custody sheets for the March 1993 analyses. 3 I l Monitorins Well Identi cation BTE&X bv EPA Test Method 824018260 MW-1 X MW-4 X MW-5 X MW-6 X MW-7 X MW-8 X School Well X ES -0903- I 9304-2001.RPT Unocal, San Luis Drive 4 April 20, 1993 7 .O DISCUSSION OF ANALYTICAL RESULTS 7.1 Benzene Benzene was not found above the Practical Quantitation Limit (PQL) of 0.5 pgll in the seven groundwater samples analyzed. The California Department of Health Services Maximum Contaminant Level (MCL) for benzene in drinking water is 1.0 Pg/|. Table 4 and Figure 4 present the concentrations and locations of benzene analytical results, respectively. 7.2 Toluene Toluene was not detected above the PQL of 0.5 Fgll in the seven groundwater samples analyzed. The DOHS Recommended Drinking Water Action Level for toluene is 100 pg/|. Table 5 and Figure 4 present the concentrations and locations of toluene analytical results, respectively. 7.3 Ethylbenzene Ethylbenzene was not detected above the PQL of 0.5 ILg/l in the seven groundwater samples analyzed. The MCL for ethylbenzene in drinking water is 680 ttgfl. Table 6 and Figure 4 present the concentrations and locations of ethylbenzene analytical results, respectively. 7.4 Total Xvlenes Total xylenes were not detected above the PQL of 0.5 Pgfi in the seven groundwater samples analyzed. The MCL for total xylenes in drinking water is 1,750 pg[. Table 7 and Figure 4 present the concentrations and locations of total xylenes analytical results, respectively. i I I.J ES-0903- I 9304-2001 .RPT Unocal, San Luis Drive 5 April 20, 1993 8.0 CONCLUSIONS Based on the data following conclusions obtained during March 1993 groundwater monitoring, the can be drawn: 1993, from Groundwater elevations measured in the monitoring wells have risen an average of g.3 feet between December lgg} and March 1993. The rise is attributable to rainfall received during this period, and is consistent with ssasonal fluctuations observed at this and other monitoring sites in the area. The calculated groundwater flow direction in March 1993 was to the south-southwest, at a gradient of approximately 0.007. The March groundwater gradient has increased very slightly since December 1992. The southerly flow direction calculated for March lggS is consistent with the flow direction calculated in December 1992 and previous monitoring events. BTE&X were not detected in groundwater samples collected on March 1, wells MW-l, MW-4, MW-5, MW-6, MW-7, MW-8, and the School Well. Crude oil thickness measurements obtained from monitoring well MW-2 indicate a decrease in product thickness from 1.92 feet in December to less than 0.01 feet in March. This decrease appears to be related to the rising groundwater levels in the monitoring area, as it has been observed at this and other monitoring sites during periods of rising groundwater; however, the mechanism for the decrease in oil thickness is unclear. A hydrocarbon sheen was observed on the surface of purge water collected from monitoring wells MW-3 and MW-10. Evidence of petroleum hydrocarbons in these wells has been observed previously. In January 1990, a trace of crude oil was observed in well MW-3. In April 1991, a trace of crude oil was observed in purge water during installation of well MW-10. In light of these previous observations, we do not believe that lateral migration of crude oil is indicated by the March 1993 data' ES-0903- 1 9304-200l.RPT Unocal, San Luis Drive April 20, 1993 In a February 25, 1.993 letrer to Unocal, the Regional Water Quality Control Board requested that an additional well be installed at the site, to monitor groundwater conditions between the former release site and San Luis Obispo Creek. A site meeting was held between representatives of ESE, Unocal and the Regional Board on March 8, 1993, and a well location was selected. The well will be installed and sampled prior to the second quarterly monitoring event. In addition, the Board's February 25 letter requested that groundwater samples be analyzed for total perroleum hydrocarbons (TPH) as diesel and crude oil, in addition to the BTEX analyses being conducted. After discussions with Regional Board personnel and research by Unocal, it has been determined that the pipeline that was broken had carried only crude oil. Thus, future monitoring events will include analysis of groundwater for TPH as crude oil and BTEX. 9.0 LIMITATION This report has been prepared for the exclusive use of the Unocal Corporation as it pertains to rhe monitoring site on the 1400 block of San Luis Drive in San Luis Obispo, California. The findings and conclusions rendered in this report are opinions based on laboratory testing of groundwater samples collected during this project.

Depths were measured to an accuracy of 0.01 feet from a designated point on the top of each well casing. Prior to use at each monitoring well, the water sensing probe and a portion of the measuring tape was washed with TSPrM (tri-sodium phosphate), rinsed with clean tap water and deionized water, then allowed to air dry to reduce the possibility of cross-contamination. The water level probe was lowered until the top of the water surface within the monitoring well was detected. Once the water surface was detected, a continuous signal from the meter sounded. The depth to water measurement was performed at least three times for each monitoring well to verify the initial measurement obtained. A final depth to water measurement was recorded on a standard form. I iJ -_-l CRUDE OIL THICKNESS ESTIMATION PROTOCOL An MMC Flexi-Dipru electronic oil/water interface meter was used to measure the depth to crude oil and depth to product lwater interface. Depths were measured to an accuracy of 0.01 feet from a designated point on the top of each well casing. Prior to use at each monitoring well, the product/water sensing probe and a portion of the measurement rape was washed with TSPrM (tri-sodium phosphate), rinsed with clean tap water and deionized water, then allowed to air dry to reduce the possibility of cross-contamination. The interface probe was lowered until the top of the product surface within the monitoring well was detected. Once the air/product interface was detected, an intermittent signal from the interface meter sounded. The interface probe was then raised above the product surface and shaken to remove excess product on the probe. The air/product interface depth measurement was performed at least three times for each monitoring well to verify the initial depth to product. Once a consistent depth to product measurement was determined and recorded, the interface probe was lowered to below the product/water interface. Once the water below the product was detected, a continuous signal from the interface meter sounded. The interface probe was then raised to the productlwater interface and a depth to watsr measurement was recorded. The product/water interface measurement was performed at least three times for each monitoring well to verify the initial depth to the product/water interface. Depth measurements were recorded on a standard form. I I J .l -l GROUNDWATER SAMPLING PROTOCOL Purging and sampling equipment was disassembled and washed with a non- phosphate detergent solution, rinsed with clean tap water and deionized water, then allowed to air dry before purging and sampling each well to reduce the possibility of cross-contamination. Prior to sampling, the groundwater monitoring wells were purged with a pre-cleaned bailer to remove stagnant water in the wells. During purging, key parameters including temperature, conductivity, and pH were measured with a portable electronic meter and noted. The meter was calibrated prior to the sampling event. Purging continued until the key parameters stabilized. Approximately three to four well casing volumes of groundwater were removed. The groundwater monitoring wells were sampled after water in the wells had recharged to approximately SOVI of the original groundwater elevation. If during purging, the monitoring well was purged dry, purging was stopped for approximately five minutes to allow the well to recharge. If the well did not recharge at a sufficient rate to continue purging the three to four casing volumes, the well was purged dry two times and allowed to recharge until sampling. Following purging, groundwater samples were collected with pre-cleaned Teflonru bailers, and discharged with a non-aerating bottom emptying device into laboratory cleaned glass containers, capped with Teflonru septa, labeled, and chilled in an ice chest for transport to a California Environmental Protection Agency certified laboratory. Water samples were handled and transported according to the Environmental Protection Agency (EPA) protocol. Sample identification and chain of custody procedures were utilized for the samples to ensure sample integrity and to document sample possession from the time of collection to its destination. The sample labels identify the job number, sampler, date and time of collection and sample number unique to the sample. -l I e APPENDIX B Laboratory ReportsandChain-of-Custody Sheets Coasr .

If potentially Affected Soil and/or Groundwater is observed during construction activities, and a CEMC-authorized representative is not on the Site, CEMC should be notified as quickly as possible to allow CEMC to profile the material and consult on the eventual disposal or reuse ofany Affected Soil, and the proper discharge or disposal of Affected Groundwater. Chevron can be contacted at 805-547-5440. A contact list is provided as "Exhibit A." 3.2 PROFILING Ai\D MANAGEMENT This SGMP was prepared in an effort to obtain a closure or'ono further action" letter from the Regional Board for the Site. Issuance of a no further action letter means that no further corrective action is required for the Site; accordingly, absent the identification of conditions that were not considered prior to issuance of the no further action letter or specific direction from the Regional Board, it is reasonable to presume that material excavated from the Site may be reused on the Site. Profiling is intended to ensure that reuse of excavated materials on the Site is consistent with the no further action determination. After receiving notification that potentially Affected Soil and/or Groundwater has been observed during Site construction activities, CEMC will arrange for a representative to collect samples of the soil and/or groundwater (either in situ or from a segregatedl stockpile) for profiling purposes. If, based on a review of the profiling results, the Regional Board prohibits excavated Affected Soil from being reused on the Site due to the presence of petroleum hydrocarbons, CEMC will coordinate with the property owner(s) regarding the proper off-site disposal of that soil. The property owner(s) should ensure that any excavated Affected Soil is stockpiled in a separate location from non-affected soil to allow for proper soil management and disposal. I If Site soits are being excavated, the property owner should ensure that potentially affected soil is stockpiled in a separate location from non- affected soil to allow for proper soil profiling and management 2 SOIL AND GROUNDWATER MANAGEMENT PLAN FORMER UNION OIL PIPELINES _ TANK FARM ROAI) 1. INTRODUCTION Chevron Environmental Management Company ("CEMC") prepared this Soil and GroundwaterManagement Plan ("SGMP") to address the management of petroleum affected soil andgroundwater present along a portion of Tank Farm Road following assessment and remediationof oil released from apair of historical S" crude oil pipelines (the "Site"). The Site encompassesan area extending west from the former San Luis Obispo Tank Farm Facility to the eastern edgeof the intersection with South Higuera Street. Portions of the Site contain petroleumhydrocarbon-affected soil or petroleum hydrocarbon-affected groundwater released from theformer pipelines ("Affected Soil andlor Affected Groundwater", respectively) which may befound up to approximately 150 feet on either side of Tank Farm Road. This SGMP providesinformation about CEMC's environmental assessment of the Site and outlines the process forproperty owners to work with it to address Affected Soil and/or Affected Groundwater that theowners may encounter during construction excavation or dewatering work. 2. SITE CONDITIONS2.I SITE DESCRIPTION Potentially affected properties within the Site are shown in Figure I and listed below by AssessorParcel Numbers: 053-251-050, 053-251-053, 053-251-054, 053-251-055, 053-251-057 , 053-Z5l-067,053-257-024,053-257-026,053-257-027,053-257-030,053-257-031,053-258-012,053_ 258-013, 053-258-029. 2.2 ENVIRONMENTAL INVESTIGATION SUMMARY In 1988, after having been notifed that properry owners along Tank Farm Road had identifiedcrude oil in soil during a soil investigation, Union Oil initiated work to determine the area andmagniture of the historical releases. Union Oil cleaned and abandoned the two pipelines inSeptember 2001, installed 39 monitoring wells over the course of its investigation andremediation project,29 of which have been removed, with 10 remaining. Upon receipt ofclosure, Union Oil will remove the remaining l0 wells. CEMC submiued a request for case closure to the Central Coast Regional Water euality ControlBoard ("Regional Board") on July 12,2014 (Case #sL203031242,iankFarm Road). 3.

A photo ionization detector does not pick up methane which I would think is fairly common in this type of investigation, so a FID would be our instrument of choice.

Even the risk to utility workers, the only group wlo may potentially be exposed to the crude oil during excavation, was studied and shown to be insignificant' Since the potential exists ror cn ae oil-imp-acted soil to be e*posed during future construction, a representative of the city of san Luis obispo requested that a generalized Health and Safety Plan (HASP) bg prepared to provide contractors with a source o1information on health and safety issues and i..o.-.nded soil handling practices. It is the objective of this document to: . provi de appropriatety trained" licensedcontractors with chemi calhazard information for the crude oil impacted soil. This information was developed with the intent that it be attached as anadfundumto a contractor's site/task-specific HASP, thus aiding in the protection of the health, safety and welfare of workers who may potentially encounter oily soil; . provide contractors with the information necessary to fulfill State and Federal hazard communication (IIAZCOIO requirements for workers who may potentially be exposed tcr oily soil; and . Minimize any further threat to the environment due to inappropriate handling of oily soil, if encountered. 2.0 LIMITATIONS The information contained in this FIASp is provided for guidance purposes only and is not intended as a substitute for the development of a site/activity-specific HASP which should be prepared by any entrty conducting work in any area. Firms requiring workers to excavate within the described vicinity must ensure that: tj tne **t i, conducted in aciordance with all Federal, State, county and city requirements; and 2) their employees are working under, and in accordance with' the firm's Injury & Illness prevention'program (Irpp), Codes oi Suf. Practice, Hazard Communication Program (HAZCOM), and Emergency Response Plan. These health and safety programs, codes and plans are the minimum required olan Lxcavation contractor by caVoSHA pursuant to Title 8 of the california Code of Regulations. Whereas the Codes, IIPP and HAZCO}/r documents are task specific (site generic), the Emergency Response Plan is a slte specific document' We recommend that this HASP be included as an addendum to a site-specific heatth and safety document (i.e., Emergency Response Plan). f HEALTH & SAFETY PLAN This HASp focuses upon chemical and ancillary hazards associated with the oily soil and material handling procedures in the event such soil is encountered. Implementation of the procedures contained herein are at the sole discretion of the entity conducting the excavation work. It does not address any other health and safety issues which rnuy b. related to an entities' or individual's area of .*p"rtir. and contains no guidanie regarding excavation procedures or techniques' England & Associates will not be responsible for implementation of this HASP and strongly suggests that appropriate ,uf.ry professionals (i.e., industrial hygienist) prepare and implement a safety prog.ur' which directly uidr"rr., the work to be preformed (i.e', a site/activity-specific HASP)' Unocat Tank Form Road Ptpellne leak Slte San 3.0 BACKGROUND Page2 1997 ENGLAND & ASSOGIATES Approximately 60 years ago, a release of heavy crude oil from Unocal's pipeline beneath Tank Farm Road in San Luis Obispo 6o*tv resulted in crude oil contamination of soil and ground water under the road and adjaceni prop.rty. The extent of oily soil, free oil on ground water and dissolved hydrocarbons in ground *"t.r -have been delineated in several studies (Brown and Caldwell, 1988, t"qgq; Dames & Moore (D&lvf), 1990; Earth Systems Consultants @SC), 1996a' 1996b)' Recent invesiigations by Earth Systems Consultants irave improved the definition of the area in which hydrocarbon concentration exceeds 100 mglkgin the ioil within the San Luis obispo City limits- psc, lgg6a,lgg6b). Figure I (attachedfttrows the site location and the approximate extent of impacted soil. The top of oily soil ranges from 8 feet deep near Tank Farm Road to 15 feet deep near the northern and southernplume riargins (ESC, 1996a,1996b, 1996c). Soil impacted by crude oil typically displays an olive gray colJr - u, oppor.d to brown which is common elsewhere. The impacted soil g.n.ruuy has a diJcernable hydroc"iuon odor and heavily impacted areas may exhibit small drops of dark brown oil in the soil Pores. 3.1 Chemical Hazard ,,AII substances are poison; there is none which is not poison. The right dose dffirentiates a poisonfrom a remedy" (Paracelcus, L493-l54l) Risk is a function of toxicity and exposure. For a toxic substance to pose a threat, the potential for exposure must exist. If there is no probable route of exposure, there is no risk. Potential routes of .*porur. include ingestion, inhalation, dermal absorption and injection' Crude oil is a naturally-occurring (i.e., unrefined), complex liquid consisting almost entirely of hydrocarbons (i.e., varying mixtures of the elements hydrogen and carbon (hydrocarbon)' Tl' pirysical prop.rti., anO itremical composition (toxicity) of crude oil vary markedly, depending on its HEALTH & SAFETY PLAN Unocsl Tonk Farm Road Pipellne Lcak Slte Page 3 .Isnurrv 7. 1997 San Luls ohlsno. Callfornla source. The primary constituents of crude oil fall into three major categories: parafifins, naphthenes, and aromatics. Many crude oil components, such as paraffins and naphthenes, are generally not considered to be highly toxic (Amdur ;t al., teet; ctayt-on and clayron, r98l) and are not typically included as chemicals of concern in assessments of health hazard' The constituents of primary concern for hazard assessment are contained in the aromatic fraction' The most toxic known compounds found in the aromatic fraction are benzene and the suspected carcinogenic polynuclear aromatic hydrocarbon (PAH) compounds (carcinogens are chemicals thought capable of causing cancer if administered in large or long-lasting doses). Noncarcinogenic compounds that may dsJ be of concern include toluene, ethylbenzene, ry^lenes, naphthalene, and other noncarcinogenic pAH compounds. In addition to their potential toxic effects, benzene, toluene, ethyl benzene and rylenes (BTEX) compounds are of concern because of their volatility and mobility in the environment, properties that increase the likelihood of exposure' BTEX compounds have been detected only infrequently in soil, and where they have been detected, their concentrations have been very low @TEX:-<0.04, <0'18, <0'07 and <0'34 mdkg) (Dames & Moore (D&M), 1990t. A more ,...nt investigation found no detectable BTEX in ten samples with measurable crude oil concentrations (Eartl Systems Consultants, 1996)' These very low concentrations are not considered sufficient to por" significant health and/or safety hazards to utility workers (England & Associates, 1996a). Aii quality monitoring for volatile hydrocarbons during construction is not necessary. Monitoringfor air qualiiy concerns unrelated to the crude oil problem (i.e., oxygen deficiency, erc.) are the responsibility of the entity conducting the work. Of eight soil samples analyzed for PAHs, twelve PAH compounds were detected (D&M, 1990)' Seven of these ur. ,urpr.ted human carcinogens and five are not. PAHs have very low vapor pressures and adsorb strongly to soil. Therifore, inhalation of vapors is not a likely route of .*porur.. potential routes of .*poru., to PAHs involve ingestion of soil, absorption through the skin (dermal absorption), and injection lOirty cuts or puncture wounds). Although it has been shown that the pAH concentrations in soil are too low io constitute a significant health threat, safe work practices and good personal hygiene can substantially reduce the potential for even low levels of exposure to PAHs. Following is a complete list of hydrocarbon constituents detected in the crude oil impacted soil, their associated Chemical Abstract Service Number (C.A.S.

The MSDS is very broad to cover a wide range of crude oils and is therefore very con;ervative. Furthermore, the cruie oil at the Tank Farm Road site has been in the ground for at ieast 60 years and has undergone extensive weathering. The effects of weathering are most profound onihe low-molecular weight fraction of the petroleum, selectively removing/reducing the more volatile and soluble constituents. Therefore, the weathered crude oil does not possess the flammability hazards described in the MSDS. 3.2 Human Exposure Hazatd Analysis AHealthRisk Assessment (HRA tF&A l996al) was conducted to address the potential for adverse health affects as a result of worker exposure to oily soil during utility construction. The HRA considered the potential threats to worker health associated with inhalation of vapors and air-borne particulates a;d direct contact (incidental ingestion and dermal contact) with oily soil during construction. The risk appraisal assumed conservatively high levels of exposure (worst-case soil concentrations) for ten (10) days (much longer than is typically required for utility installation) so as to not underestimate the threat. The results of the HRA indicate that the site is safe for utility workers under the conditions considered. Both potential carcinogenic risk and noncarcinogenic hazard are considered acceptable under Catifornia Dipartment of Toxic Substance Control and United States Environmental Protection Agency guidelines. It is important to note that the assumptions and approaches used in developing th; Iil,A were designed toensure that potential risks were not underestimated. For example, risk assessments typicafy utilize average concentrations to estimate chronic risks associated with long- term exposur*r, ho*auer, the maximum reported concentrations of hydrocarbons in soil were used in the calculation of potential risks. Any actual risks associated with the Tank Farm Road Pipeline site are likely to be much less than estimated in the HRA analysis, and may, in fact, be zero. 4.0 RECOMMENDATIONS IN THE EVENT OILY SOIL IS ENCOUNTERED In the event oily soil is encountered we recommend that the following measures be implemented: ENGLAND & ASSOGOATES HEALTH & SAFETY PLAN Unocal Tank Farrn Road Plpellne l,eok Stte Luls Callfornla Page 5 1991 ENGLAND & ASSOGIATES Notifl (Jnocal: Notify Unocal immediately at (805) 348-3.1.26' Be prepared to provide an accurate work area location (i.e., nearby int.rr.Jtns, property address or map page and grid locatiol) ana description of the work being performed. unocat may, at its discretion, provide a technician to document the condition, .n.ountered and oversee soil segregation and stockpiling' Establish Designaled Work Areas: Access to work areas surrounding an excavation exposing oily soil and the oily soil stock pile should be controlled by erecting temporary.barriers' Only authorized workers wearing upprou.o personal protective equipment shall be permitted within the designated work area. Eatins, iri"r,i"j and smoking should be discouraged within the designated work area' penonal hotective Equipment: Although the health risk assessment demonstrated that the potential for adverse health effects as a result oT construction in the oily soil area is negligible, personal protective measures should be implemented to minimize contact with oily material' To achieve this goal atl work shatl be conductei in Level D personal protective equipment (PPE)' Level D PPE includes: long pants and long-sleeved shirts, it"rt-toei boots, gloves, hartl hat and safety glasses ' personal Hygiene: To avoid accidently ingesting oily soil, eating, drinking and smoking shoulcl be discouraged within the duignated wirk-*ro. -otty toil may be transferred to food by dirty hands or air-borne dust may settle orifood containers (i.e., soda cans) resulting in unintentional ingestion' hior to eating, drinking or smoking and at the'eni of the work day, thoroughly wash hands and face with soap and water. fufinimize @osure: To the extent possible, minimize physical entry into any trench or pit exposing oily soil. Moterial Handling: Minimize the amount of oily soil excavated. Excavate only what is necessary to complete the tasl at hand. visibly oily soil sttouto be stockpiled separately_ from other excavated material. The material should be stockpiled onto plastic sheeting and covered.by securely anchored pr*,i" sheeting. The purpose of covering the oily soil is to minimize the potential for human contact, not to suppress uupoi, (since volatile constituents are not present). Therefore, if the oily soil is to be moved later the Lrn ouy, covering may be unnecessary. bity soil should not be placed back into any excavation without written authorization' 5.0 OTHER REQUIRED PLANS As was pointed out previously, the purpose of this document is to provide chemical hazard and material handling information for-parties excavating within the area of impacted soil' The document is not intended as a substitute for the developrJ-tt of " site/activity-specific HASP as required by cayosHA.

The assessment consisted of dritling 20 soil borings, and laboratory analysis of 6t soil samples for total extractable petroleum hydrocarbons. The intent of the wotk was to evaluate the distribution of hydrocarbons adjacent to two Unocal Corporation petroleum pipelines which are prcsent south of the site, beneath the Tank Farm Road right-of-way. Total extractable pecoleum hydrocarbons were detected in 9 of the 20 borings drilled in the study area. TEPH concenrrations ranged from 37 to 23,000 mglkg, and had a carbon chain length of CtO to C36. The highest concentrations of TEPH were found in borings GPS-9 and GPS-10, in the western part of the study area. TEPH was not detected by laboratory analysis in soils shallower than 16 feet below ground surface, and was not detected above 100 mg/kg in samples from depths below 30 feet below ground sutface. The distribution of the hydrocarbons beneath the site appears to be conEolled at least in part by the type of sediments present. In the qNtern portion of the site, hydrocarbons do not apryar to extend more than 40 feet north of Tank Farm Road, with the exception of an 8-inch thick layer in the vicinity of boring GPS-3. Soils in this area are predominantty clayey, with subordinate clayey sand and clayey gravel layers. In the western portion of the site, hydrocarbons are present approximately 160 feet north of Tank Farm Road; soils in this area are predominantly coarse-grained between 14 and 28 feet below grade. Below 28 feet, TEPH concentrations attenuate rapidly in the underlying clayey soils. Groundwater was encountercd in 14 of the 20 borings, at depths ranging from 13 to 28 feet below ground surface. The groundwater was prcsent in granular sediment horizons, which appear to be discontinuous across the site. Groundwater was not encountered the remaining six borings, which were drilled to maximum depths of 36 feet bgs. The static water level in wells south and southwest of the study area varied from 8.5 to 13 feet below ground sutface in June 1996. il iIt_ Unocal-S trasbau gh Properly 1 July 12, 1996 1 . O INTRODUCTION This report presents the results of a subsurface site assessment conducted on the Strasbaugh property in San Luis Obispo, California. The assessment was performed with the intent to evaluate the distribution and extent of petroleum hydrocarbons adjacent to a Unocal pipeline easement which parallels the south side of the site. Work performed in this assessment has consisted of: a a Drilling 20 exploratory borings to a modmum depth of 38 feet below grade Collection of soil samples from various depths in the borings l.aboratory analysis of 61 soil samples for total extractable pefoleum hydrocarbons ([EPH) Data analysis and preparation of this report'a 2.0 BACKGROUND The study area is a2}-aqe parcel situated on the north side of Tank Farm Road, east of Long Street" in San Luis Obispo, California (see Figure 1). The site contains a vacant fietd, which is presently being used for agricultural purposes. The property is situated in an area of commerciaUindustrial and agricultural zoning. The Tank Farm Road right-of-way contains an easement for two Unocal peuoleum pipelines, which are located approximate|y 25 feet south of the subject site's south properfy line. Assessments of soil and groundwater conditions in the Tank Farm Road area between Higuera Street and the Unocal Tank Farm were conducted in 1988 and 1989 (Brown & Caldwell, 1988, 1989; Dames & Moore, 1990). A total of seven exploratory borings were drilled on the site during these prior investigations. Petroleum hydrocarbons were found in an elongated zone roughly paraltel to Tank Farm Road. A norttrward-extending zone of hydrocarbons in the western part of the study area was also identified in the investigations. A monitoring well (SLOW-l3) was installed in the northwest part of the subject site in 1988; this well was monitored on a quarterly basis until lgg4, when it was destroyed in accordance with State regulations during the construction of Long Street. During the course of quarterly monitoring, petroleum hydrocarbons were not detected in SLOW-I3. NGL-10173-01 9606-098.RPT Unocal-S trasbau gh Property July 12, 1996 Soil samples from four of the exploratory borings from these earlier assessments contained as much as 3,990 milligrams per kilogram (mg/kg) of total recoverable petroleum hydrocarbons; most of these samples were analyzedby EPA Method 418.1, rather than by the more accurate analytical method of gas chromatography/mass spectroscopy (GC/MS) that has been used in recent assessments of crude oil sites. The intent of the current assessment was to define the 100 mdkg boundary of TEPH in soils beneath the site, using a more accurate and precise analytical method and more closely spaced borings, prior io the property's proposed development 3.0 REGIONAL GEOLOGY AND HYDROGEOLOGY The subject site is situated at the eastern end of the Los Osos Valley, a northwest-trending valley which extends from the San Luis Obispo Airport area to Morro Bay. The valley is underlain by Recent alluvium deposited by San Luis Obispo and Prefumo Creeks, consisting of mostly fine grained deposits of silt and clay, with interbedded sand and gravel. The alluvium is underlain by metamorphic rocks of the Franciscan Formation and sedimentary rocks of the Monterey Formation (Hall and Prior, 1975). The primary structural feature in the area is the Los Osos fault, which is situated approximately one mile south of the site. Groundwater in the area of the site is produced primarily from Recent alluvium, although some deeper wells produce water from fractuned rocks of the Franciscan and Monterey Formations (CDWR, 1970). County well construction standards require a minimum SGfoot deep sanitary seal for supply wells in this area. Depth to first groundwater varies widely in the vicinity of the site, and appears to depend mostly on infiltration from precipitation and the presence of lenses of permeable sediments. Based on data collected from quarterly groundwater monitoring between 1990 and 1996, depth to groundwater in the perched aquifer beneath the site has varied seasonally from 3 to 22 fegt below ground surface (bgs). The regional groundwater gradient direction in the perched aquifer is to the west-southwest. Aquifer pumping tests performed on properties to the south and southwest of the subject site indicate that the degree of communication between the upper perched aquifer and lower aquifer is negligible (England-Shahin & Associates, 1992; England & Associates, 1996). 2 NGL-10173-01 9606-098.RPT 3 July 12,1996Unocal-S trasbau gh Property t t 4. O FIELD INVESTIGATION Drilling and Soil Sampling On May 13, 14,15 and 17, 1996, a total of 20 soil borings were advanced at the locations shown on Figure 2. Prior to drilling, Underground Service Alert (USA) was notified to mark utilities in the area to avoid damage by subsurface exploration. The borings were advanced using a Geoprobe G5400 direct push sampling rig, using l.S-inch diameter core. The borings were sampled at discrete intervals, as shown on the boring logs. Review of approximately 45 boring logs from prior investigations of the site and surrounding properties along Tank Farm Road indicates that petroleum hydrocarbons have not been observed in the field or detected by laboratory analysis in soils shallower than 14 to 16 feet bgs. Consequently, many of the borings in this assessment were advanced directly to 12 to 14 feet below grade to begin sampling. This procedure allowed more borings to be drilled and more accurately define the contaminated zone, which was found to be present at depths from 16 to 30 feet below grade. A California Registered Geologist was present to log the borings, collect soil samples and monitor soils for field evidence of hydrocarbons. Hydrocarbon vapors were monitored with a photoionization detector (PID), calibrated to isobutylene. Drilling and sampling equipmeht was cleaned between borings to reduce the potential for cross-contamination. After sampling, the borings were backfilled with bentonite chips and hydrated. Boring logs are attached as Appendix A. Lahoratory Analysis of Soil Samples Laboratory analysis was performedatZymaxEnvirotechnology in San Luis Obispo. A total of 6l soil samples were submitted for analysis. The samples were analyzed for total extractable petroleum hydrocarbons (TEPH) by gas chromatography/mass spectroscopy (GC/MS, equivalent to EPA Test Method 8270). NGL-r0173-01 9606-098.RPT r l Unocal-S trasbau gh Property 4 July 12, 1996 I Site Survey A survey of the boring locations, property boundaries and the edge of pavement of Tank Farm Road and Long Street was prepared by Engineertng Development Associates of San Luis Obispo. Figures 2 and 3 are adapted from the EDA survey drawing. 5.0 FINDINGS OF FIELD INVESTIGATION Soil Conditions Earth materials beneath the site consist of of several feet of dark brown sandy clay topsoil, underlain by sandy clay and gravelly clay, with interbedded gravelly sand, clayey sand and silty clay layers. Boring locations are shown on Figure 2. Soils in the eastern part of the site are predominantly clayey, with lesser amounts of clayey sand and clayey gravel. In the western part of the site, a gravelly zone was encountered in borings at a depth of approximately 14 to 28 feet below ground surface. The gravel layer is underlain by a clayey silt horizon that was encountered at about 28 feet below grade. In all of the borings in which hydrocarbons were detected, field indications of hydrocarbons (odor, staining) were not observed at depths shallower than 12 feet below ground surface. The depth to the top of the hydrocarbon plume increases with distance from Tank Farm Road; in many of the borings, evidence of hydrocarbons was not observed at depths shallower than 18 to 21 feet below grade. PID readings ranged from 31 to 460 parts per million by volume (ppmv), in borings GPS-3, GPS-8, GPS-9 and GPS-10, GPS-11, GPS-12, GPS-16 and GPS-18. The highest readings were generally obtained from samples collected between L8 to 24 feet bgs. PID readings are recorded on the boring logs. PID reading in the remaining borings were non-detectable. Groundwater Conditions Groundwater was encountercd in 14 of the 20 borings, at depths ranging from 13 to 28 feet below ground surface. The groundwater was prcsent in granular sediment horizons, which appear to be discontinuous across the site. Groundwater was not encountered in borings GPS-1, GPS-2, GPS-7, GPS-15, GPS-16, and GPS-17, which were drilled to maximum depths of 36 feet bgs. I NGL-10r73-01 9606-098.RPT Unocal-Strasbaugh Property July 12, 1996 Static water levels in wells adjacent to the site ranged from 8 to 14 feet below ground surface in June 1996. 6.0 RESULTS OF LABORATORY ANALYSIS Total extractable petroleum hydrocarbons (TEPH) were detected in 20 of the 61 soil samples submitted for laboratory analysis. TEPH concentrations ranged from 37 to 23,000 milligrams per kilogram (mglkg, or parts per million); the carbon chain length of the hydrocarbons detected ranged from C1g-to C36, which is within the typical range of crude oil. TEPH was not detected in any of the remaining 4l samples analyzed, with a practical quantitation limit of 10 mg/kg. Laboratory results of soil samples are summarized in Table 1. Boring locations and results of laboratory analysis and are plotted on Figure 3. Figure 4 presents cross-sections across the study area, showing analytical results as reported by laboratory testing. The approximate extent of TEPH in soils is also shown on Figures 3 and 4.

These borings were situated in the southern part of the properry, adjacent to Tank Farm Road. TEPH concentrations ranged from 37 to 23,000 mg/kg, and had a carbon chain length of CtO to C36. The highest concentrations of TEpH were found in borings GPS-9 and GPS-10, in the westem part of the study area. TEPH was not detected by laboratory analysis in soils shallower than 16 feet below ground surface, and was not detected above 100 mglkg in samples from depths below 30 feet below ground surface. The distribution of the hydrocarbons beneath the site appears to be controlled at least in part by the type of sediments prcsenl In the eastern portion of the site, hydrocarbons do not appear to extend more than 40 feet north of Tank Farm Road. Soils in this area are predominantly clayey, with subordinate clayey sand and clayey gravel layers. An exception to this pattern is boring GPS-3' which is approximately 100 feet north of Tank Farm Road. TEPH was detected in GPS-3 at a concentration of 870 mg/kg at a depth of 21 feet below grade; however, the hydrocarbon-affected interval in this boring is less than 10 inches thick, and probably does not rcpresent a large volume of contaminated soil in this area- In the western portion of the site, hydrocarbons are present approximately 160 feet north of Tank Farm Road; soils in this area are predominantly coarse-grained between 14 and 28 feet below grade. Below 28 fet,TEPH concentrations attenuate rapidly in the underlying clayey soils. 8.0 LIMITATION This report has been prepared for the exclusive use of the Unocat Corporation, regarding the Strasbaugh property San Luis Obispo, California.

Please provide a map showing the location of your on-site drinking water well and details of well construction if available to enable us to evaluate any risk to your water supply. However, it is our understanding that the wells you are referring to in your letter are groundwater monitoring wells and not drinking water supply wells. Water goard staff requireJresponsible parties to properly abandon all groundwater monitoring wells after we have determined that investigation and cleanup is completed in order to prevent cross contamination of aquifers by wells that can act as conduits for pollution as they age and deteriorate. We request that you allow CEMC access to your propedy so that they may abandon the groundwater monitoring wells, as required by Water Board staff. lf you refuse access, we have the legal authority to require you to remove the wells at your own expense. However, if you have a legal document that requires CEMC to maintain the wells in perpetuity, please provide it to this office by January 5, 2015, and we will re-evaluate the requirement for abandonment of the groundwater monitoring wells. We also want to inform you that we have notified the City and County of San Luis Obispo to ensure that they are aware of remaining soil and groundwater pollution, and we have not received objections from them on the proposed site closure. We plan to proceed with closure. CEMC will continue to be responsible for contamination and a program is in place to address any pollution that is encountered in the future. We hope this letter addresses your concerns. lf you have additional questions, please contact Alison Jones of my staff at Alison.Jones@waterboards.ca.qov or at (805) 542-4646, or John Robertson at (805) 5424630.

The Water Board is overseeing cleanup of the Unocal Tank Farm Road Pipeline Site, which runs along a portion of Tank Farm Road on the outskirts of the City of San Luis Obispo. Over time, the section of pipeline between Unocal's former tank farm facility and South Higuera Street leaked petroleum hydrocarbon compounds into the surrounding soil and groundwater. At the direction of the Water Board, Unocal began collecting data to define the nature and extent of the petroleum hydrocarbon release in 1988. Site Background Unocal operated a tank farm facility north and south of Tank Farm Road from 1910 to the early 1980s. During the operational use of the tank farm, crude oil was transported via pipelines from the San Joaquin Valley to the tank farm, as well as to distribution points along the California coast. The pipeline that ran along Tank Farm Road was removed from service in the mid-1990s, and formally decommissioned (cleaned and sealed) in 2001. Unocal conducted preliminary investigation work in 1988 after crude oilwas discovered in soil beneath properties along Tank Farm Road. Total petroleum hydrocarbons (TPH) detected in soils ranged from 540 to 44,000 milligrams per kilogram (mg/kg), or parts per million, above San Luis Obispo County Environmental Health Services' TPH soil screening level of 100 mg/kg. Between 1988 and 2003, Unocaldrilled approximately 170 exploratory borings and installed 34 groundwater monitoring wells to define the extent of petroleum impacts to soil and groundwater. The site consists of a linear zone of crude oil-impacted soil and groundwater approximately 2,200 feet long and 100 to 300 feet wide, stretching from west of the former tank farm to South Higuera Street, at depths of 10 to 30 feet. Much of the impacted soil and groundwater lies beneath Tank Farm Road. ln addition to soil and groundwater sampling, Unocal completed a health risk assessment, conducted aquifer tests to determine whether petroleum constituents could move into deeper water supply wells, and conducted a study to look at indicators of naturally occurring biodegradation. Unocal and later Chevron Environmental Management Company (CEMC) have monitored groundwater at the site since 1989. During the most recent sampling event in March 2014, none of the samples had detectable concentrations of TPH in the lighter, more volatile gasoline range and none had detectable concentrations of Dl.

This notification describes the site background,previous environmental investigations, and rationale for closure. 2IPublic Notice Tank Farm Road Pipeline Site benzene, ethylbenzene, toluene or xylenes (BTEX) or fuel oxygenates such as methyl tert-butyl ether (MTBE) A subset of the samples had relatively low concentrations of TPH in the moderate to heavy carbon range; however, analytical results indicate natural biodegradation of the petroleum hydrocarbons continues to occur. Rationale for Glosure Water Board staff recommends closure of this case based on the following 1. The extent of pollutants in soil and groundwater has been adequately characterized.2. Remedial options to actively remove remaining pollution are limited due to the predominance of fine-grained soils beneath the site, the highly viscous character of the crude oil which adsorbs to soil and soil pores, and development along Tank Farm Road, which makes excavation and disposal of impacted soilextremely expensive and would create a significant public disturbance.3. Remaining petroleum hydrocarbons in groundwater are confined to shallow groundwater and are not migrating; wells downgradient of the plume did not have detectable concentrations of TPH when last sampled in 2006.4. Remaining petroleum hydrocarbons in soils and groundwater are in a stable plume that is undergoing natural biodegradation.5. The depth of petroleum hydrocarbon-impacted soil and groundwater (10 to 30 feet below ground surface) makes contact with pollutants unlikely. ln addition, CEMC has developed a site soil and groundwater management plan (SGMP) to ensure proper handling of site soils and groundwater should they be exposed during future activities. A copy of the SGMP is available on the State Water Resources Control Board's GeoTracker case web page at: http://qeotracker.waterboards.ca.qov/reoulators/deliverable documents/9739729166ffank%20Far m%2ORoad%2OPipeline%2OSGMP Final.pdf6. Aquifer tests have shown that groundwater from the shallow zone does not migrate to deeper wells.7. The County of San Luis Obispo requires 50-foot seals on allwater supply wells to prevent cross- contamination of aquifers; any groundwater wells installed in the plume area would be sealed throughout the impacted area, which extends to approximately 30 feet.8. The City of San Luis Obispo now supplies water to developed properties along Tank Farm Road, reducing the need for groundwater supply wells. Water Board staff believes there is no significant threat to human health or the environment from the remaining pollution at this site. No further soil or groundwater monitoring, investigation or cleanup is necessary at the site, based on evaluation of existing data and information.

You requested that Water Board staff consider terminating or revising the covenant to release the western 5.25 acres of the property from land use restrictions so as to facilitate easier real estate transactions that will result in management of the 5.25 acres as a regional ponding basin. You told Water Board staff at the April 21 meeting that there is a drainage easement on the western 5.25 acres of the property, and the City of San Luis Obispo has prescribed that acreage as a regional ponding basin for the western enclave of land included in the City of San Luis Obispo's Mardarita Area Specific Plan. You stated it did not appear that land use restrictions2 were appropriate for the ponding basin area for the following reasonsl 1 Water Board staff and Union Oil of California (a wholly owned subsidiary of Chevron) executed a Covenant and Envircnmental Restriction on Propefty (covenant) for property that is currently within the San Luis Obispo city limits, and is immediately north of the Chevron/Union Oil of California San Luis Obispo Tank Farm. The covenant was prepared, signed, and recorded with the San Luis Obispo County ClerURecorder as Document 200657837 in August 2006' At that tiie, Union Oil of California was the owner of the property described as APN 076-341-012, Lots 34 and 41, and the parcel was not yet annexed into the San Luis Obispo city limits. The property is currently owned by Prado Park, LLC and is in the process of gaining approval from the San Luis Obispo City Council for subdivision into two separate parcels. ' The covenant restricts owners or occupants of the property from drilling, installing, or using a well for extraction of water for any use unless expressly permitted in writing by the Water Board. ln addition, the owner or occupant is restricted from disturbing soii Oetween 10 and 15 feet below grade without a soil management plan and a health and safety plan approved by the City of San Luis Obispo Fire Department. l-)c, Jr,nu-Prr urr VVr-'Ltf , t:rrtn I Ktrlrut ttr A.

Although part of APN 076-341-012 contains petroleum hydrocarbons from a former oil pipeline leak, the area impacted by the petroleum hydrocarbons does not coincide with the ponding basin acreage.2. The C1y of San Luis Obispo provides municipal water service to the area, thereby significantly reducing the likelihood of a property owner installing a supply well.3. ltis highly-unlikelythe land would be used in the future for anything otherthan a regional ponding basin. ln addition, you told Water Board staff the property addressed in the covenant was in the process of being subdivided in order to segregate the ponding basin acreage from the remainder of the parcel. Water Board staff understands that after subdivision, the 5.25-acre area will be assigned a new parcel number, and the current property owner (Prado Park, LLC) intends to sell the 5.25 acres to Rescal SLO 193, which is the entity developing the Serra Meadows residential development north of the subject property. We also understand that you are affiliated with the Serra Meadows development. ln a May 14,2014letter to Mr. Ken Harris from Mr. Wally Taylor (managing member of Prado Park, LLC), Mr. Taylor indicated Rescal SLO 193 subsequently iirtenOJ to sell the 5.25 acres of ponding basin to the Serra Meadows Homeowners Association (SMHA) for future management. Based on our discussion on April 21,2014, we understand that sale of.the 5.25 acres 1o the SMHA will not occur unless the land is free of any land use restrictions. Please be advised that Water Board staff intends to amend the covenant to exclude land use restrictions on the ponding basin acreage. We concur that land use restrictions are unnecessary for the 5.25 icres, but we maintain the restrictions are appropriate for the remaining portion of APN 076-341-012, Lots 34 and 41 due to petroleum hydrocarbons released from an oit pipetine that extended north across the parcel from the Chevron/Union Oil of California Tank Farm property. The amended covenant will take some time to complete due to the need for legal review and signatures from appropriate Water Board staff and the current property ownerJ. As with the covenant signed in 2006, we will require the property owner to iecord ihe amended covenant with the San Luis Obispo County Clerl</Recorder within ten days of the covenant's execution. lf you have any questions, please contact diane.kukol@waterboards.ca.qov, oI Thea thea.tryon@waterboards.ca. gov.

Detailed assessments of the contamination have established that the crude oil does not pose a threat to human health or the environment. Even the risk to utility workers, the only group who may potentially be exposed to the crude oil during excavation, was studied and shown to be insignificant. Since the poiential exists for crude oil-impacted soil to be exposed during future construction, a representativeff tn. City of San Luis Obispo requested that a generalized Health and Safety Plan (IIASP) be prepared io provide contraciors with a source of information on health and safety issues and iecommended- soil handling practices. It is the objective of this document to: Provide appropriotely trained" Iicensedcontractors with chemical hazard information for the crude oil-impacted ioil. This information was developed with the intent that it be attached as an addenilum to a contractor's iite/tosk-specific HASP, thus aiding in the protection of the health, safety and welfare of workers who may potentially encounter oily soil; Provide contractors with the information necessary to fulfill State and Federal hazard communication (FIAZCOM) requirements for workers who may potentially be exposed to oily soil; and Mnimize any further threat to the environment due to inappropriate handling of oily soil, if encountered. 2.0 LIMITATIONS The information contained in this FIASP is provided for guidance purposes only and is not intended as a zubstitute for the development of a site/activity-specific HASP which should be prepared by any entity conducting work in my r*. Firms requiring workers to excavate within the described vicinity *uri .nrure that: l) the work is conducted in accordance with allFederal, State, County and City requirements; and 2) their employees are working under, and in accordance with, the firm's Injury & Illness Prevention Program (IIPP), Codes of Safe Practice, Hazard Communication Program (I{AZCOM), and Emergency Response Plan. These health and safety programs, codes and plans are the minimum required of an excavation contractor by CaVOSFIA pursuant to Title 8 of the California Code of Regulitions. Whereas the Codes, IIPP and HAZCOM documents are task specific (site generic), thelmergenry Response Plan is a site specific document. l/'e recommend that this HASP be included as an addendum to a site-specifc health and safety document (i.e, Entergency Response PIan).

The extent of oily soil, free oil on ground water and dissolved hydrocarbons in ground- *rt.r have been delineated in several studies (Brown and Caldwell' 1988, f 'qSg; Dames & Moore (D&lO, 1990; Earth Systems Consultants (ESC), 1996a, 1996b). Recent invesiigations by Earth Systems Consultants irave improved the definition of the area in which hydrocarbon concentration exceeds 100 mg/kg in the soil within the San Luis Obispo City limits (ESC, lgg6a,lgg6b). Figure 1 (attached)-shows the site location and the approximate extent of impacted soil. The top of oily soil ranges from 8 feet deep near Tank Farm Road to 15 feet deep near the northern and southernplume riargins (ESC, 1996a, 1996b, 1996c). Soil impacted by crude oil typically displays an olive gray color - as opposed to brown which is common elservhere. The impacted soil g.n.rulty has a discernable hydrocarbon odor and heavily impacted areas may exhibit small drops of dark brown oil in the soil Pores. 3.1 Chemical Hazard ,,AII stbstances are poison; rhere is none which is not poison. The right dose dffirentiates a poisonfrom a rente$t" (Paracelcus, 1493-1541) Risk is a function of toxicity and exposure. For a toxic substance to pose a threat, the potential for exposure must exist. If there is no probable route of exposure, there is no risk. Potential routes of .*potutt include ingestion, inhalation" dermal absorption and injection' Crude oil is a naturally-occurring (i.e., unrefined), complex liquid consisting almost entirely of hydrocarbons (i.e., u.rying *i*tui.i of the elements hyilrogen and carbon (hydrocarbon)' The physical properties and chemical composition (toxicity) of cruae oil vary markedly, depending on its ENIGLAND & ASSOGOATES HEALTH & SAFETY PI-AN Unocsl Trnk Ferrn Roed Ptpellnc l*ak Slte Janusil Pege 3 1.1997 San Luls Obbpo,Callfornls I source. The primary coniiituents of crude oil fall into three major categories: paramns, naphthenes, and aromatics. Many crude oil components, such as paramns and naphthenes' are generally not considered to be highry toxic (Amdur ;t al., test; ctayton and clayron, r9s1) and are not typically in.iua.a as chemicals of concern in assessments of health hazard. The constituents of primary concern for hazard assessment are contained in the aromatic fraction' The most toxic knoivn compounds founl in the aromatic fraction are benzene and the suspected carcinogenic polynuclear aromatic hydrocarbon (P.$! compounds (carcinogens afe chemicals thought capable of causing cancer if administered in.large or longJasting doses). Noncarcinogenic compounds that may also be of concern include toluene, ethylbenzene, xylenes, naphthalene' and other noncarcinogenic pAH compounds. In addition to their potential toxic effects, benzene, toluene, ethyl benzene and rylenes (BTDq compounds are of concern because of their volatility and mobility in the environment, properties that increase the likelihood of exposure' BTEX compounds have been detected only infrequently in-soil, and where they have been detected' their concentrations have been very low (BffX,'.0.0i, <0.i8, <0.07 and <0'34 mg/kg) (Dames.& Moore (D&M), 1990). A more recent iniestigation found no detectable BTEX in ten samples with measurable crude oil .onr.ntrations Gaitr Systems Consultants, 1996)' These very low concentrations are not considered sufficient to pot. significant health and/or safety hazards to utility workers (England & Associates, 1996a). Air quality monitoring for volatile hydrocarbons during construction is not necessary. Monitorinjfor air qualiiy concerns unrelated to the crude oil problem (i.e., oxygen deficiency, etc.) are the responsibility of the entity conducting the work' Of eight soil samples analyzed for PAHs, twelve PAH comPounds were,detected (D&I"{' 1990)' Seven of these ur. ,urp..ted human carcinogens and five are not. PAFIs have very low vapOr pressures and adsorb itrongly to soil- Ther-efore, inhalation of vapors is not a likely route of exposure. potentialroutes of exposure to pAHs involve ingestion of soil, absorption through the skin (dermal absorption), and injection (drty cuts or puncture wounds). Although it has been shown that the pAH concentrations in soil are too low to constitute a significant health threat, safe work practices and good personal hygiene "an zubstantially reduce the potential for even low levels of exposure to PAHs.

The MSDS is very broad to cover a wide range of crude oils and is therefore u.ry.o,ri.*ative. Furtherrnore, the cruie oil at the Tank Farm Road site has been in the ground for at ieast 60 years and has undergone extensive weathering. The effects of weathering are most profound onih.low-molecular weight fraction of the petroleum, selectively removing/reducing the more volatile and soluble constituents. Therefore, the weathered crude oil does not possess the flammability hazards described in the MSDS. 9.2 Human Exposure Hazard Analysis AHealth Risk Assessment (HRA tE&A 1996a]) was conducted to address the potential for adverse health affects as a result of worker .*poruri to oily soil during utility construction. The HRA considered the potential threats to workei health associated with inhalation of vapors and air-borne particulate, und direct contact (incidental ingestion and .dermal contact) with oily soil during construction. The risk appraisal assumed conservatively high levels of exposure (worst-case soil concentrations) for ten (10)'days (much longer than is typically required for utility installation) so as to not underestimate the threat. The results of the HRA indicate that the site is safe for utility workers under the conditions considered. Both potential carcinogenic risk and noncarcinogenic hazard are considered acceptable under Califomia Department of Toxic Substance Control and United States Environmental Protection Agenry guidelines. It is important to note that the assumptions and approaches used in developing tfri ffna were designed to ensure that potential risks were not underestimated. For example, risk assessments typically utilize average concentrations to estimate chronic risks associated with long- term exposurar, ho*.uer, the maximum reported concentrations of hydrocarbons in soilwere used in the calculation of potentiat riiks. Any attual risks associated with the Tank Farm Road Pipeline site are likely to be much less than estimated in the }IR'A analysis, and may, in fact, be zero. 4.0 RECOIVINIENDATIONS IN THE EVENT OILY SOIL IS ENCOUNTERED In the event oily soil is encountered we recommend that the following measures be implemented: Benzo @) lluoranthene Benzo (k) fluoranthene Bcruo(g,h$ perylenc Chtl:ene.

Detailed assessments ofthe contamination have established that the crude oil does not pose a threat to human health or the environment. Even the risk to utility workers, the only group who may potentially be exposed to the crude oil during excavation, was studied and shown to be insignificant. Since the poiential exists for crude oil-impacted soil to be exposed during future construction, a representative of tnr City of San Luis Obispo requested that a generalized Health and Safety Plan (HASP) be prepared io provide contractors with a source of information on health and safety issues and recommended soil handling practices. It is the objective of this document to: . provi de appropriatcty trained, Iicensedcontractors with chemi calhazard information for the crude oil impacted soil. This information was developed with the intent that it be attached as an adfundum to a contractor's site/task-spec{ic HASP, thus aiding in the protection of the health, safety and welfare of workers who may potentially encounter oily soil; . Provide contractors with the information necessary to fulfill State and Federal hazard communication (HAZCON4) requirements for workers who may potentially be exposed to oily soil; and . Minimize any further threat to the environment due to inappropriate handling of oily soil, if encountered. 2.0 LIMITATIONS The information contained in this HASP is provided for guidance purposes only and is not intended as a substitute for the development of a site/activity-specific HASP which should be prepared by any entrty conducting work in any area. Firms requiring workers to excavate within the described vicinity must ensure that: l) the work is conducted in accordance with all Federal, State, County and City requirements; and 2) their employees are working under, and in accordance with, the firm's Injury & Illness Prevention Program (IIPP), Codes of Safe Practice, Hazard Communication Program (HAZCOM), and Emergency Response Plan. These health and safety programs, codes and plans are the minimum required of an excavation contractor by CaVOSHA pursuant to Title 8 of the California Code of Regulitions. Whereas the Codes, IIPP and HAZCOM documents are task specific (site generic), the Emergency Response Plan is a site specific document. ll/e recommend that this HASP be included as an addendum to a site-speciJic health and safety document (Le, Emergency Response Plan). t fL tL ENGLAND & ASS@GIATTES rr t i- HEALTH & SATETY PLAN Unmal Tank Farm Road Plpellne t €ak Slt€Page 2 Januan 7. 1997 San Luts Oblsno. Callfornla This HASp focuses upon chemical and ancillary hazards associated with the oily soil and material handling procedures in the event such soil is encountered. Implementation of the procedures contained herein are at the sole discretion of the entity conducting the excavation work. It does not address any other health and safety issues which maibe related to an entities' or individual's area of expertise and contains no guidance regarding excavation procedures or techniques' England & Associates will not be responsible for implementation of this HASP and strongly suggests that appropriate safety professionals (i.e., industrial hygrenist) prepare and implement a safety progru[ which directly aidresses the work to be preformed (i.e., a site/activity-specific HASP)' Approximately 60 years ago, a release of heavy crude oil from Unocal's pipeline beneath Tank Farm Road in San Luis Obispo 6o*tv resulted in crude oil contamination of soil and ground water under the road and adjaceni prop.iy. The extent of oily soil, free oil on ground water and dissolved hydrocarbons in ground *ut.r have been delineated in several studies @rown and Caldwell, 1988, tbgq; Dames & Moore (D&lO, 1990; Earth Systems Consultants (ESC), 1996a,1996b)' Recent invesiigations by Earth Systems Consultants irave improved the definition of the area in which hydrocarbon concentration exceeds 100 mg/kgin the ioil within the San Luis obispo City limits- psc, lgg6a,lgg6b). Figure I (attachedl stto*s the site location and the approximate extent of impacted soil. The top of oily soil ranges from 8 feet deep near Tank Farm Road to l5 feet deep near the northern and southernplume riargins (ESC, 1996a,1996b, 1996c). Soil impacted by crude oil typically displays an olive gray color - as opposed to brown which is common elsewhere. The impacted soil generaily has a discemable hydroc"iuon odor and heavily impacted areas may exhibit small drops of dark brown oil in the soil Pores. 3.0 BACKGROUI{D 3.1 Chemical Hazard ,,All substances are poison; there is none which is not poison. The right dose dffirentiates a poisonfrom a remedy" (Paracelcus, I493-I54I) Risk is a function of toxicity and exposure. For a toxic substance to pose a threat, the potential for exposure must exist. If there is no probable route of exposure, there is no risk' Potential routes of exposure include ingestion, inhalation, dermal absorption and injection' Crude oil is a naturally-occurring (i.e., unrefined), complex liquid consisting almost entirely of hydrocarbons (i.e., varying mixtuies of the elements hydrogen and carbon (hydrocarbon)' The pirysical properties anA cneiical composition (toxicity) of crude oil vary markedly, depending on its t t t- L ENGLAND & ASS@G[ATES r r-HEALTH & SAFETY PLAN Unocal Tank Farm Roed Plpellne t €ak Stt4 Page 3 Januarl 7' 199?San Luls Callfornla f-t source. The primary constituents of crude oil fall into three major categories: paramns, naphthenes, and aromatics. Many crude oil components, such as paramns and naphthenes' are generally not considered to be highli toxic (Amdur it al., 1991; claytbn and clayton, 1981) and are not typically included as chemicali of concern in assessments of health hazard' The constituents of primary concern for hazard assessment are contained in the aromatic fraction. The most toxic known compounds found in the aromatic fraction are benzene and the suspected carcinogenic polynuclear aiomatic hydrocarbon (PAH) compounds (carcinogens are chemicals thought-capabie of causing cancer if administered in large or long-lasting doses). Noncarcinogenic ,ornf,ounds that may alsJ be of concern include toluene, ethylbenzene, ry_lenes, naphthalene, and othei noncarcinogenic pAH compounds. In addition to their potential toxic effects, benzene, toluene, ethyl benzene anJrylenes (BTEX) compounds are of concern because of their volatility and mobility in ihe environment, properties that increase the likelihood of exposure' BTEX compounds have been detected only infrequently in soil, and where they have been detected, their concentrations have been very low (BTEX:-<0.04, <0.18, <0.07 and <0.34 mdkg) (Dames & Moore (D&M), 1990). A more reient investigation found no detectable BTEX in ten samples with measurable crude oil concentrations (Earth Systems Consultants, 1996), These very low concentrations are not considered sufficient to pose significant health and/or safety hazards to utility workers (England & Associates, 1996a). Aii quality monitoring for volatile hydrocarbons during construction is not necessary. Monitoringfor air quality concerns unrelated to the crude oil problem (i.e., oxygen deficiency, erc.) are the responsibility of the entity conducting the work. Of eight soil samples analyzed for PAHs, twelve PAH compounds were detected (D&M, 1990)' Seven of these "r" ,urp.ited human carcinogens and five are not. PAFIs have very low vapor pressures and adsorb sirongly to soil. Therifore, inhalation of vapors is not a likely route of f*por*". potential routes ofixposure to PAHs involve ingestion of soil, absorption through the skin (dermal absorption), and injection (Oirty cuts or puncture wounds). Although it has been shown that the pAH concentrations in soil are too low io constitute a significant health threat, safe work practices and good personal hygiene can substantially reduce the potential for even low levels of exposure to PAHs.

I Unocal has provided alvlaterial SafetyData Sheet (MSDS) to cover sweet crude oil (Attachment Ai following tire text). The MSDS is very broad to cover a wide range of crude oils and is therefore very cons=ervative. Furthermore, the crude oil at the Tank Farm Road site has been in the ground for at ieast 60 years and has undergone extensive weathering. The effects of weathering are most profound onihe low-molecular weight fraction of the petroleum, selectively removing/reducing the more volatile and soluble constituents. Therefore, the weathered crude oil does not possess the flammability hazards described in the MSDS. 3.2 Human Exposure Hazard Analysis A Health Risk Assessment (I{RA tF.&A l996al) was conducted to address the potential for adverse health affects as a result of worker exposure to oily soil during utility construction' The HRA considered the potential threats to worker health associated with inhalation of vapors and air-borne particulates a;d direct cont&ct (incidental ingestion and dermal contact) with oily soil during construction. The risk appraisal assumed conservatively high levels of exposure (worst-case soil concentrations) for ten (10) days (much longer than is typically required for utility installation) so as to not underestimate the threat. The results of the HRA indicate that the site is safe for utility workers under the conditions considered. Both potential carcinogenic risk and noncarcinogenic hazard are considered acceptable under California Dlpartment of Toxic Substance Control and United States Environmental Protection Agency guidelines. It is important to note that the assumptions and approaches used in developing th; Iil,A were designed to ensure that potential risks were not underestimated. For example, risk assessments typically utilize average concentrations to estimate chronic risks associated with long- term exposurar, ho*auer, the maximum reported concentrations of hydrocarbons in soil were used in the calculation of potential risks. Any actual risks associated with the Tank Farm Road Pipeline site are likely to be much less than estimated in the HRA analysis, and may, in fact, be zero. 4.0 RECOMMENDATIONS IN THE EVENT OILY SOIL IS ENCOUNTERED In the event oily soil is encountered we recommend that the following measures be implemented: t_ t_ ENGLAND & ASSOGIATES rIl f- I HEALTH & SAFETY PLAN Unocal Tank Farm Road Plpellne [*gk Slte Page 5 Januarv 7,1997San Luls Oblsno. Notify (Jnocal: Notrfy Unocal immediately at (805) 348-3.1.26. Be prepared to provide an accurate work area location (i.e., nearby intersectitns, property address or map page and grid location) and description of the work being performed. Unocal may, at its discretion, provide a technician to document the conditions enc;;tered and oversee soil segregation and stockpiling. Estahlish Designated Work Areas: Access to work areas surrounding an excavation exposing oily soil and the oily soil stock pile should be controlled by erecting temporary.barriers' only authorized workers wearing uppro.r.d personal protective equipment shall be permitted within the designated work area. Eating, irinting and smoking should be discouraged within the designated work area' penonal hotective Equipment: Although the health risk assessment demonstrated that the potential for adverse health effects as a result o}construction in the oily soil area is negligible, personal protective measures should be implemented to minimize contact with oily material- To achieve this goaloll work shall be conductei in Level D perconal protective equipment (PPE). Level D PPE t hd.r, long pants and long-sleeved shirts, steel-toed boots, gloves, hard hat and safety glasses' personal Hygiene: To avoid accidently ingesting oily soil, eating, drinking and smoking should be discouragedwithin the designatedwirk area oly soil may be transferred to food by dirty hands or air-borne dust may settle orifood containers (i.e., soda cans) resulting in unintentional ingestion' hior to ealing, drinking or smoking and at the end of the work day, thoroughly wash hands and face with soap andwater, fufinimize Erytosure: To the extent possible, minimize physical entry into any trench or pit exposing oily soil. Malerial Handting: Minimize the amount of oily soil excavated. Excavate only what is necessary to complete the task at hand. Visibly oily soil should be stockpiled separately_ from other excavated material. The material should be stoct<pited onto plastic sheeting and covered by securely anchored plastic sheeting. The purpose of covering the oily soil is to minimize the potential for human contact, not to suppress vapors (since volatile constituents are not present). Therefore, if the oily soil is to be moved later the *r. duy, covering may be unnecessary. Oily soil should not be placed back into any excavation without written authorization. s.o oTHER REQUTRED PLANS As was pointed out previously, the purpose of this document is to provide chemical hazard and material handling information for partiis eicavating within the area of impacted soil. The document is not intended as a substitute for the development of a site/activity-specific I{ASP as required by CayOSHA. It is strongly recommended that any entity considering excavation in any area prepare and implement a health-and safety plan that addreises thi physical hazards associated with the specific t.

This document should be provided to the City/County of San Luis Obispo agency(ies) responsible for issuing construction/excavation permits. The City/County should provide copies of this document to contractors applying for excavation permits in the affected area. Moreover, contractors bidding on public worki projects should be provided a copy of this document together with the other bid documents and thi bid documents should be written so as to require contractors to include this plan in their taslc/project-specific health and safety plan. 6.0 SELECTED REFERENCES Admur, M.O., Doull, J., and Klaasen, C.D., @ds.) 1991, Cassarett and Doull's Toxicology: The Basic Science of Poisons, 4th ed.

The extent of oily soil, free oil on ground water and dissolved hydrocarbons in ground water have been delineated and characterized in several studies. The objective of this corrective action plan is to evaluate the site assessment data and recommend an appropriate response based on the protection of human health and the environment. The subject property is currently vacant, but historically has been used for agricultural purposes. The City of San Luis OUispo's General Plan Land Use Element calls for the area (the property is part of the "Airport Area") to be eventually annexed into the city. The Airport Area Specific Plan indicates that the iubject site and all ofthe surrounding properties will be zoned "services and manufacturing." The nearest residential areas are located approximately t/o-mile to the west (west of South Higuera Street) and north (north of Prado Road). Site assessment data indicate that the oil in the subsurface is comprised of high-molecular weight compounds with very low concentrations of polynuclear aromatic compounds and BTEX. The crude oil eitends onto the proposed Farrn Supply property for a distance of 15 to I l0 feet, covering an area of about 0.6-acre. Consistent with an off-site buried pipeline source, detectable concentrations of petroleum hydrocarbons beneath the property are limited to depths deeper than 5 feet and shallower ihan}l feet bgs (Earth Systems Environmental,lggT). TPH is occasionally detected in ground water samples from monitoring wells situated down-gradient ofthe crude oil impacted area (up to 3 mgll), but BTEX and PNAs are rarely detected. On the few occasions when these have been detected, their concentrations have been very low. The subject property is located in the San Luis Valley, a relatively level, narrow, alluvium-filled basin. The alluvium, which consists of approximately 160 feet of laterally discontinuous interbeds of gravel, sand, silt and clay, comprises the major ground water aquifer in the San Luis Obispo ground water basin. In the site vicinity, poor quality, semi-confined ground water has been measured at depths ranging from 7 to more than 30 feet below ground surface. The potentiometric surface slopes to the southwest (mean flow direction:S65oW) with a gradient ranging from approximately 0.002 to 0.008 fooVfoot (Figure 3). The RBCA evaluation follows the traditional four-step process defined by the National Academy of Sciences and the USEPA for developing risk assessments. These steps included: Evaluation of available data to identiff chemical constituents of potential concem; An exposure assessment to identify scenarios under which human populations may be exposed; a I ENGLANDGEffiY51EMENVIRONIVIENTAL ENGINEERING EXECUTIVE SUMMARY Risk-Based Corrective Action Plan Proposed Farm Supply Property, San Luis Obispo Countv. California Page ES-2 March l,2000 a a A toxicity assessment, in which the toxicities ofconstituents ofpotential concern are evaluated, and toxicity indices are identified for use in characterizing potential risk; and The calculation of appropriate risk-based screening levels (RBSLs - media concentrations which are protective of human health and the environment). Based on the results of the data evaluation, the RBCA evaluation focused on three classes ofhydrocarbon compounds: Aromatic compounds (i.e., benzene, toluene, ethylbenzene, and xylenes); PAHs including acenaphthene, benzo(a)anthracene, benzo(b)fluoranthene, benzo(k)-fluoranthene, benzo(g,h,i)perylene, benzo(a)pyrene, chrysene, dibenzo(a,h)anthracene, fluoranthene, fluorene, indeno(1,2,3-c,d)pyrene, phenanthrene, and pyrene; and a a a TPHs including diesel/residual range organics. Environmental media considered in the RBCA evaluation included air, subsurface soils, and groundwater. In evaluating these media, the following human exposure scenarios were considered: Future on-site commercial/industrial workers who may be exposed to volatile organic constituents emitted from the soil and ground water into the atmosphere or into enclosed spaces; a o An on-site utility worker who may be exposed to on-site soils during excavation or utility installation, as well as to airborne fugitive dust and volatile organic constituents; and On- or off-site workers who may be exposed to ground water from wells that may be installed down-gradient of the site. Safe exposure levels and other toxicity information were identified for each of the constituents evaluated in the RBCA analysis. Sources of this information included current DTSC and USEPAguidance. In addition, surrogate compounds were selected to characterize the potential toxicity ofpetroleum hydrocarbon mixtures. This approach is consistent with recent guidance developed by the Massachusetts Department of Environmental Protection (l 994). The results ofthe RBCA evaluation indicate that maximum concentrations of the site constituents of concern in subsurface soil and ground water do not exceed the risk-based screening levels (RBSLs). Therefore, the site does not pose a threat to current or future commercial/industrial users of theproperty, intrusive construction workers, or down-gradient workers using ground water.

In reviewing the results ofthis evaluation, it should be recognized that the assumptions and approachesused herein were designed to ensure that potential risks were not underestimated. Any actual risks associated with the property are likely to be much less than estimated in this analysis, and may, in fact, be zero. In the event that future development results in significant changes to site grades in the vicinityof the soil impacts, this risk evaluation should be updated to reflect the changed conditions. During construction, it is possible that deep excavations could encounter oil-stained soils. To addressthis possible scenario, a contingency plan for encountering crude oil impacted soil has been prepared and is attached as Appendix B.

California 1.0 INTRODUCTION Crude oil released from a pipeline serving Unocal's tank farm facility in San Luis Obispo, California, has resulted in contamination of soil and ground water underlying the pipeline and adjacent areas. The nature and extent of this contamination has been extensively studied and described (Pacific Geosciences, 1988; BrownandCaldwell, 1988and 1989; DamesandMoore,1990; EarthSystems Environmental, several reports dated l990,lg9l,lgg2,l996 and 1997;Earth Systems Consultants Northem Califomia, t99g; parth Systems Pacific, 2000; England, Shahin and Associates, 1990, l99l and l99};England & Associates, 1996c). A detailed Health Risk Assessment of the soil and ground water contamination prepared by England, Shahin and Associates (dated October 1990) was submitted to the California Regional Water Quality Control Board - Central Coast Region (RWQCB). This report presents a risk-based corrective action (RBCA) evaluation of a currently vacant 5-acre property proposed for commercial development: the proposed Farm Supply property (APN 076-351- b:f)(pigur"i;. fn" purpose of this study is to evaluate the site assessment data and recommend an appropriate response based on the protection of human health and the environment. This plan was pr.pui.A in accordance with the guidelines established in American Society for Testing and Materials'^faSrfrrri document entitled Standard Guide for Risk-Based Corrective Action (RBCA) at Petroleunt Release Sites, November lgg5, E 1739-95. The RBCA decision process integrates risk and exposure assessment practices, as suggested by the United States Environmental Protection Agency (USEPA)' with site assessment activities and remedial measure selection to ensure that the chosen action is protective. 2,0 BACKGROUND The following sections provide a summary of pertinent site history and characterization data needed to recommend an appropriate response based on the protection of human health and the environment. 2.1 Site Description The proposed Farm Supply property is a rectangular,5.}Z-acre property located on the north-side of Tani Farm Road approximaiely %-mile east of south Higuera Street (Figures I and2). The property is located ,ru".ui hundred feet east of the City of San Luis Obispo corporate boundary, in unincorporated San Luis Obispo County, California. The site is currently vacant, covered by a variety of non-native grasses, but histtrically was used for agricultural purposes. The site is bordered by the Cook Business park on the west, cultivated agricultural fields on the north and east, and Tank Farm Road on the south. Commercial/industrial properties (A&R Welding and Union (San Luis Ready Mix) occupy the areas south of Tank Farm Road. No surface water bodies or well-defined surface water drainages are located on the property. Only the south-edge of the property bordering Tank Farm Road is affected by the crude oil release' t t ENGLAND G@SYSTEN4 E NVI RON IMENTAI ENGI NEERI NG t- r- I t I RISK-BASED CORRECTIVE ACTION PLAN Proposed Farm SupplY ProPertY Page2 Mav 5. 2000San Luis Countv. California The City of San Luis Obispo's General Plan Land Use Element calls for the proposed Farm Supply property to be eventually annexed into the city. The Airport Area Specific Plan indicates that the property will be zoned for commercial serviceilight manufacturing development' 2.2 Site Investigation HistorY Unocal's Tank Farm Road pipeline runs parallel to and beneath Tank Farm Road, west of the former San Luis Obispo tank farm. The pipeline is actually a pipeline system which has been renewed over the years. Theoriginal pipeline along Tank Farm Road went in about 1910 with line renewal projects in 1930 and 1952. The current pipeline consists of two, 8-inch diameter steel pipes which were installed in about 1952 and removed from service in the mid-1990s. Interviews with longtime residents of the tank farm area suggest that the pipeline rupture responsible for the crude oil contamination occurred in or around 1936 (Brown & Caldwell, 1988). In April 1988, local landowners notified Unocal that crude oil contamination of soil and ground water had been detected beneath their properties during real estate pre-purchase soils investigations (Pacific Geosciences, Inc., l9S8). Unocal subsequently retained Brown and Caldwell to initiate an investigationto define the limits of the affected soil and ground water (1988, 1989). Dames and Mooreltgg0) and Earth Systems Consultants (1996a, 1996b,1996c, 1997) were later retained to further delineate the impacts. These assessments resulted in the drilling of 122 exploratory borings, the installationof 27 ground water monitoring wells, and the delineation of a roughly linear zone of hydrocarbon contamination approximately 200 feet wide by 2000 feet long (Figure 2). England & Associates (E&A) has conducted studies, including ground water pumping and computer mo-cleling which demonstrate that the oil and the individual hydrocarbon compounds which make up the oil are not migrating from the impacted zone (England, Shahin & Associates, l990a,l 990b, 1992a, 1992b;England & Associates, 1996). Most soil and ground water analyses have shown non-detectable concentrations of the more toxic and mobile BTEX (benzene, tolueneo ethylbenzene and xylenes) components. On the few occasions when these have been detected, their concentrations have been very low. A health risk assessment of exposure to contaminated soil and ground water conducted in 1990 showed acceptable risk from leaving the crude oil in the subsurface. Long-term pumping tests in two widely sepaiated wells screened beiow 50 feet depth demonstrated that hydrocarbons are not drawn into wells scieened at depths in which water production wells could legally be completed (England, Shahin & Associates, 1992a;England & Associates, 1996a). More than a decade of quarterly ground water monitoring has shown that the dissolved hydrocarbon plume is not expanding and has stabilized near the oily zone in the 60f years since the leak occurred.

Numerous exploratory and water well borings drilled in the site vicinity indicate that this alluvium consists of approximately 160 feet of laterally discontinuous interbeds of gravel, sand, silt and clay. The lithologic logs indicate that fine grained lithologies, silt and clay, are-predominate in the upper 100 feet, whereas coarse lithologies, sand and gravel, are predominate at depth. The alluvium rests unconformably upon bedrock ofthe Franciscan Formation. The alluvium comprises the major ground water aquifer in the San Luis Obispo ground water basin' At the site, ground water has been measured at depths ranging from 7 to more than 30 feet below ground rurfu-"". Both long term and seasonal fluctuations in groundwater levels have been recorded' Observations of rising *uirr levels in exploratory borings indicates that the shallow ground water is largely semi-confined with local confined and unconfined zones. The potentiometric surface slopes to the southwest (mean flow direction:S65oW) with a gradient ranging from approximately 0.002 to 0.00g foot/foot (Figure 3). Recharge apparently occurs over the entire aquifer mainly through precipitation events. A ground water quality study of the San Luis Obispo Airport area (Cleath, 1986) concluded that ground water quuiity in the airpo rt areais poor and generally does not meet drinking water standards. Total dissolved solids (TDS), nitrate, and chloride concentrations commonly exceed recommended drinking water standards. N4any of these water quality impacts (i.e., nitrate, chloride, TDS) are attributed to the septic systems that serve the businesses and residences in the Airport Area' Annexation ofthe Airport Area will provide sewer service to the business and residence areas resulting in abandolment of the septic systems and will eventually improve ground water quality. 2.4 Contaminant Distribution 2.4.1 Soil Twenty (20) borings have been drilled and sampled on the proposed Farm Supply property. Fifty-eight (Sg) soii samples obtained from these borings have been tested for total petroleum hydrocarbons irpnl. Twenty (20) of the 58 samples (34%) contained detectable levels of TPH at concentrations ianging from 95 to 13,000 mdkg. The average concentration ofTPH in the 20 samples is about 1,700 mg/kg. Figure 4, a Site Plan Detail of the proposed Farm Supply property, depicts the interpreted areal dis-tribution of petroleum in soil and Figure 5, Cross Sections A-A' and B-B', depicts the interpreted vertical extent of petroleum in soil. Figure 4 indicates that the lateral extent of crude oil in soil has been successfully delineated and that crude oil extends onto the proposed Farm Supply property for a distance of l5 to I 10 feet, covering an area of about 0.6 acre. Consistent with an off-site buried ENGLANDG@SYSTEMENVIRONMENTAL ENGINEERING RISK-BASED CORRECTIVE ACTION PLAN Proposed Farm Supply ProPertY Page 4 Mav 5- 2000SanLuis Obisoo Countv. California pipeline source, detectable concentrations of petroleum hydrocarbons are limited to depths of deeper tnan S feet and shallower than 40 feet bgs. The vertical plume distribution is shown in the cross section (Figure 4). 2.4.2 Ground Water Currently, there are 23 ground water wells monitoring the Tank Farm Road pipeline release. Ofthese, 9 wells ioutinely contain measurable accumulations of crude oil and 7 wells are regularly monitored as part of the quarterly monitoring program required by Regional Water Quality Control Board - Central Coast Region (RWeCB). The largest crude oil thicknesses are obtained from wells located on the Spice Hunter property, located several hundred feet west ofthe proposed Farm Supply property on the south-side ofTank Farm Road (Figure 3). Although TPH is occasionally detected in monitoring wells situated down-gradient ofthe crude oil impacted area (up to 3 mgll),BTEX and PNAs are rarely detected. On the few occasions when these have been detected, their concentrations have been very low. Two monitoring wells (SLOW-I and SLOW-I l) were installed on the subject site in 1988 and periodically monitored for fluid levels and water quality beginning in August 1989- Well SLOW- I is situated within the TPH-impacted area and well SLOW-I1 was located about 200 feet up-ground water gradient of the impacted area. Well SLOW- 1, which occasionally contains a trace accumulation of crude oil, is not sampled for laboratory analysis at this time. Well SLOW-I was sarnpled on ten occasions between August 1989 and June 1993. TPH was detected in six of the water samples at concentrations ranging from 0.78 to 15.6 mglL. TPI{ was not detected (<0.2 mg/L) in samples collected during the last two sampling events (March and June, 1993) and the aromatic hydrocarbons, benzene, toluene, ethyl benzene and total xylenes (BTEX), have never been detected in a water sample from the site. Well SLOW-l I was sampled on four occasions between August 1989 and June 1990. Neither TPH nor BTEX has ever been detected in a water sample from up-gradient well SLOW-I1' In October 1996, well SLOW-I I was destroyed in accordance with State and local regulations. Prior to being destroyed, SLOW-I I was sampled and analyzed for TPH and BTEX. Neither were detected in the water sample. Section 3.1 contains a more detailed discussion of the nature of the crude oil impacts' 3.0 RISK ASSESSMENT AND CORRECTIVE ACTION GOALS The RBCA process integrates EPA risk assessment practices with traditional remedy selection activities in order to determine cost-effective measures for protection of human health and environmental resources. Under RBCA, petroleum release sites are characterized in terms of sources, transport mechanisms, and receptors. Risks/hazards associated with each exposure pathway are ENGLANDGEffi;Y51EMENVI RON I\J]ENTAL ENG I NEER I NG t- r i RISK-BASED CORRECTIVE ACTION PLAN Proposed Farm SupplY ProPertY San Luis Obisoo Countv. California Page 5 Mav 5. 2000 quantified and corrective action goals consistent with "acceptable" risk/hazard levels are determined. Remedial measures are then applied as needed to achieve the corrective action goals. Such risk-based corrective action can be achilved by addressing any step in the exposure process: l) removing or treating the source, 2) intenupting contaminant transport mechanisms, or 3) controlling activities at the point of exposure. The RBCA process has been designed with a tiered approach involving increasingly sophisticated levels of data collection and analysis. Tier I of the RBCA process, a generic screening level approach, involves comparison of site constituent concentrations to generic risk-based screening levels (RBSLs) to determine whether corrective action is required. Under Tier 2, site specific target levels (SSTLs) for soil and ground water clean-up goals are determined on the basis of site-specific information and/or points of exposure. Simple analytical models are employed in conjunction with additional site data to calculate Tier 2 SSTL values in a manner consistent with EPA-recommended practices. A Tier 3 evaluation involves more complex risk and exposure assessment requiring more detailed site information, probabilistic data analysis, and/or numerical fate and transport modeling. The Tier I analysis, is by far the most conservative, because upper bound (i'e., worst-case) exposures are assumed. If the upper bound exposure estimates are protective of human health, then other more refined determinationi of risk/hururd iTi"rs 2 and/or 3) will also be protective, and no further analysis is needed. The RBCA approach utilized herein is that of the Tier I evaluation. Tier 1 involves the following sequence of principal tasks: . Site Assessment - Characterize the nature and extent of the unauthorized release and site specific conditions relevant to potential migration pathways and receptors. Presented in Section 2.0 of this rePort. . Site Classification and Initial Response Action - Classif, site by the urgency of need for initial response action. If necessary, initiate response action to mitigate acute risks or further assess site conditions. . Tier I Evaluation - Using site assessment information, identify potential sources, transport pathways, and exposure pathways. Calculate appropriate risk-based screening levels (RBSLs - mediaconcentrations *hi.h u.. protective ofhumanhealth) and compare these values with site conditions to assess the need for corrective action. The principal difference between a standard EPA-style risk assessment and the RBCA approach to risk-based decision making is that the EPA method calculates the risk/trazard associated with contaminant concentrations and the RBCA method assumes acceptable risklhazard levels and back-calculates soil contaminant concentrations that are protective. The difference is illustrated by the equations on the following page. t.

Crude oil is not a chemical compound; it is a mixture consisting of potentially thousands of different chemical compounds comprised of hydrogen and carbon (hydrogen+carbon:hydrocarbon). Each of the compounds comirising the mixtuie has a defined number of carbon atoms (generally ranging from I to aO) and a ,p""ifi" altomic structure that determine its unique physical properties (i.e', solubility [ability to diss-olve in water], volatility [ability to evaporate into air], etc.). It is the relative proportion of the various types of hydrocarbon compounds in the mixture that determine the physical properties of the mixture. For instance, crude oils containing greater proportions of low molecular weight hydrocarbons (compounds comprised of 4 to l0 carbon atoms iCo-C,J) are more volatile and soluble (i.e., mobile in the environment) than crude oils containing a gr.ut.i;roportion of high molecular weight hydrocarbons (compounds comprised of greater than l0 Iarbon uto,,-,, [>C,o]). cruoe oil associat.d *itttth. Tank Farm Road pipeline release consists largely of high mole"ula.*eight compounds containing between I I and 35 carbon atoms (Crt-Crt)' The principal petroleum product stored at the San Luis Obispo tank farm and transmitted by the pipelines slrviling the facility was San Joaquin valley crude (SJVC). San Joaquin valley Crude is comprised primarily of aliphatic hydrocarbons (71%) with lesser amounts of aromatic hydrocarbons eg"h)(A.D. Little, lggq: A[phatic hydrocarbons are of relatively low toxicity/mobility (Amdur et al., I 99 I ; Clayton and Ciayto", t gg t ) and are not individually considered in risk. assessments. The constituents of primary .on.".n in fresh crude oil are contained in the aromatic fraction' Aromatic compounds inciude benzene, toluene, ethylbenzene, and xylenes (BTEX) and the carcinogenic and non-carcinogenic polynuclear aromatic hydrocarbons (PAHs). BTEX and PAH compounds are ENGLANDG@SYSTEMENVI RON IM FNTAL ENGI N EER ING ll RISK-BASED CORRECTIVE ACTION PLAN Proposed Farm SuPPIY Property Pagel Mav 5. 2000SanLuis Obisoo Counfv, Califomia frequently used in characterizing potential risks and cleanup requirements for petroleum sites because this group of chemicals includes the most toxic TPH constituents and represents a broad range of phyJical and chemical properties (solubility, volatility, etc.) influencing environmental mobility. When petroleum is released into the environment, changes in composition take place as a result of weatheiing. The main weathering processes are dissolution in water, volatilization, and biodegradation. Weathering removes the most soluble (low molecular weight aromatic hydrocarbons), volatiL (low molecular wei-ght aliphatic hydrocarbons) and biodegradable (C,o-Cx n-alkanes [aliphatic hydrocarbons]) petroleum constituents. The result is a petroleum residue that is enriched in immobile, high molecular weight compounds and depleted of carcinogenic compounds (benzene and certain eaffg (TpHCWG ,7o1.2, igqs). Crude oil at the proposed Farm Supply property has been in the ground for 60 years or more and is highly weathered. Because it is impossible to identiff all ofthe chemical compounds present in crude oil, the compounds are usually d"r.iib.d interms ofclasses ofcompounds (i.e., fractions) with similarboiling point ranges and carbon numbers. A frequently utilized method of carbon range differentiation is that recommended by the Massachuietts Department of Environmental Protection (MDEP, 1994)' The MDEP method considers the following hydrocarbon fractions: (Co-C,o (Gasoline Range Organics [GRO or TPH-GRO]), C,o-Cr, (Diesel Rung" organics [DRO or TPH-DRO]), and crr-coo(Residual i.ung. organics tnrio oi rFn-nnol). chemical compounds within each hydrocarbon fraction lcarfion range) behave similarly in the invirorunent and have similar toxicity values (i.e., compounds with 4 to 10 carbon atoms [Co-C,o] have similar physical properties). For characterization purposes' the carbon ranges of 5l petroi"u*-i-pucted soii samples collected at the Tank Farm Road pipeline release site were determined. The results of these analyses reveal that the crude oil consists almost entirely of C,,-C' hydrocarbons (Diesel/Residual Range Organics [DRRO]) with essentially no Gasoline Range futgattics (BTEX occurs in the gasoline range). This is significant because Diesel/Residual Range Organics are essentially immobile in the environment. The following sections summarize the occurrence of the constituents of primary concern on the proposed Farm SuPPIY ProPertY. 3.1.2 Chemicals of Potential Concern - BTEX . The light aromatic compounds, benzene, toluene, ethylbenzene and xylenes (BTEX) have been detectid only infrequenlly in soil, and where they were detected, their concentrations have been very low. Ftr example, of seven (7) soil samples with elevated TPH, benzene was detected only twice, and its highest concentration was only 0.04 mdkg, toluene was detected four times up io u111u*imum concentration of 0.18 mg/kg, ethylbenzene was detected once at 0.07 mg/kg' and xylenes were detected six times at concentrations up to 0.34 mdkg (D&M, 1990). A more recent investigation found no detectable BTEX at detection limits of 0.005 mdkg in ten soil samples with measurable TPH (ESC,l996a)'t_.

California Concentrations ofthe BTEX compounds have been detected even more infrequently in ground water from monitoring wells immediately down-gradient of the oily soil (ESC,2000). Wells OMW-I, OMW-2, OMW-3 and SLOW-4 are down-gradient of areas containing high concentrations ofTPH in soil and free oil floating on the shallow ground water (F'igure 3). Yet in the past ten years of quarterly monitoring and analysis of 149 samples from these four wells, benzene has been detecied only twice, toluene and xylenes have been detected four times and ethylbenzene has not been detected. The single detected benzene concentration was 2-l 1t'g/l (parts per billion). The highest toluene and xylene concentrations were 1.8 pgll and 1.4 pgll, respectively. 3.1.3 Chemicals of Potential Concern - TPH petroleum hydrocarbons are present in the subsurface soil (5 to 40 feet below ground surface) under Tank Farm Road and adjacent property. Concentrations in excess of 100 mg/kg total petroleum hydrocarbons (TPH) are present from west of the Unocal tank farm offices, approximateiy 1,700 feet west to Long Street and extend 100 to 200 feet north and south of the rig.r of Tank Farm Road (Figure 2). Three-hundred and fifty-four (354) soil sampies frotn l4b borings (l22borings and27 monitoring wells) have been tested for TPH (Table l). Of the 354 soil samples tested, 152 (43%) contained detectable concentrations of TPH. TPH concentrations in these samples range from 6 to 24,000 mg/kg, with an average concentration of about 2,600 mgikg. Fifty-eight (58) soil samples from 20 exploratory borings characterize the nature and extent of crude oil at the proporid Fur- Supply property (Table I ). Crude oil occurs beneath the site at depths of betweenabout 5 and 2l feetbelow ground surface (bgs) and at concentrations ranging from 95 to 13,000 mg/kg (Figure 5). The highest TPH concentration was detected in the gy, feet bgs soil sample collected from boring B-3, located in the center of the property immediately north of the edge of Tank Farm Road. A summary of the TPH analytical results for soil samples collected from the entire Tank Farm Road pipeline release site and the proposed Farm Supply property are presented in Table l. The highest TPH and other petroleum constituent concentrations from the entire Tank Farm Road pipeline release site (which includes the proposed Farm Supply property) and not the highesl concentrations from the subject property will be used in the risk calculations. a tI a a I tt_ t_ tt_ ENGLANDG@SYSTEMENVIRONIMENTAL ENGINEEFING r i t'RISK-BASED CORRECTIVE ACTION PLAN Page9Proposed Farm SuPPIY ProPertY California 42 35 3 l.l 4l 27 1.8 0.57 39 6 0.58 0.14 2'1 8 l.l 0.3 No. of Samples No. with Detected TPH Max.

California and March and June 1990 samples from each of these four wells showed all PAH compounds to be non-detectable (ESE, 1990). 3.2 Toxicity Assessment The constituents ofpotential concern at the proposed Farm Supply property are high molecular weight petroleum hydrocaibons associated with weathered crude oil. Various studies have shown that the-tt.u,ry hydrocarbon compounds exhibit very low toxicity because their size limits absorption by the .*por.d organism (lRp, l9g9). No EPA-approved toxicity indices are currently available for quantitatively assessing chemical mixtures such as crude oil, however. Some risk assessment guidance documents (i.e., ASTM, 1996) suggest that a risk assessment should focus on selected specific constituents (i.e., toluene, naphthalene), rather than attempt to characterize the toxicity of the petroleum mixture. An alternative approach involves characterizing potential risk associated with all ieported discrete constituents, a well as using surrogate compounds to characterize the potential toxicity of hydrocarbon mixtures. This is the approach that was utilized in developing the risk assessment for the proposed Farm Supply property' Toxicity data (carcinogenic slope factors and reference doses) were identified for each constituent of potential concem from DTSC and USEPA toxicity databases. Consistent with DTSC requirements, ihe primary source of toxicity information used in this risk assessment is the current list of "ur.inogrnic slope factors prepared by the Office of Health Hazard Assessment (California EPA, lg94). thir info.mation is supplemented with toxicity data from the Integrated Risk Information System 02S). Equivalency factors were used to relate the toxicity of the carcinogenic PAHs to benzo(a)pyrene, following current California EPA and USEPA guidance (California EPA, 1994; USEPA,-1993). Toxicitl-information for the constituents of potential concern are summarized in Table 4. Both inhalation and oral toxicity values are presented, when available. Surrogate compounds were selected to represent the toxicity of the hydrocarbon mixtures considered in this risk assessment (TpH-DRRO). Surrogate compounds are constituents for which there is toxicity information available and which can be used in a risk assessment to evaluate potential exposures to an entire mixture. The use of surrogate compounds allows the development of a de^fensible, quantitative risk assessment, even in the absence of mixture-specific toxicity data. Furthermore, the use of surrogate compounds ensures the protection ofhuman health because typically the most toxic compound in a petroleum mixture is selected as the surrogate' Following the methodology of MDEP (lgg4),n-nonane was selected as the surrogate compound to characterize the TpH-DnRO nydtocarbon mixture. This is a health protective approach. The potential toxicity of the TPH-DRRO mixture is expected to be less than the toxicity associated with n-nonane for the following reasons: I L- t_ ENGLANDG@SYSTEMENVIRONMENTAL ENGINEERING r rII RISK-BASED CORRECTIVE ACTION PLAN Proposed Farm SuPPIY ProPertY Page 12 May 5, 2000San Luis Obispo County . California a The oral reference dose developed for n-nonane was based on an analysis of the comparative toxicity of n-nonane and n-hexane by the Massachusetts Department of Environmental proteciion (MDEP). In developing the oral reference dose for n-nonane, it was recognized that the modes of action for the two compounds are likely to be different, and that a simple way to account for this difference involves ihe application of a standard, ten-fold uncertainty factor. (That is, it is assumed that the toxicity oi n-ttonutt" is an order of magnitude less than the toxicity of n-hexane.) Application of this uncertainty factor represents a health-protective upproach to estimatin! a .ef"rerrce dose, and is consistent with accepted toxicological methods' Iiis worth noting, hoiever, that, inherent in this approach is the assumption of conservatism, and that the actual toxicity of n-nonane may be significantly lower than that estimated by the MDEP reference dose. In this corrective action evaluation, the reference dose for n-nonane was selected to characterize TPH mixtures in the range of TPH-DRRO (i.e., hydrocarbon compounds with l0 to 40 carbons, expressed as C,o-Coo o,, th" laboratory data sheets) to ensure that any potential health effects associated with the more toxic, lighter-end hydrocarbons were assessed' It is likely, however, that the use of n-nonane to characterize the toxicity of the TPH-DRRO mixtures significantly overestimates potential risks, since it is expected that TPH-DRRO mixtures are dominated by the less toxic, heavier hydrocarbon molecules (based on the results of the recent sampling uni on the likelihood that weathering processes resulted in the loss or degradation of lighter hydrocarbon molecules)' I t ar tt ENGLANDG@SYSTEMENVIRONMENTAL ENGINEERING ) RISK.BASED CORRECTIVE ACTION PLAN Page 13Proposed Farm Supply ProPertY 5Luis Table 4 Summary of Toxicity Indices Tank Farm Road Pipeline Site San Luis Obispo, California Toluene Ethylbenzene Xylenes Acenaphthene Benzo(g,h,i)perylene Fluoranthene Fluorene Phenanthrene Pyrene TPH.DRRO Constituent Noncarcinogenic 0.2 (r) 0.r (r) 20) o.06 (r) 0.03 (P) 0.04 (r) 0.04 (r) o.o2 (wN) 0.03 (r) 0.6 (M) Oral RfD, (mg/kg/day) and Source 0.114 0) 0.286 (r) 0.2 (D NA NA NA NA NA NA 0.6 (N,t/R) Inhalation Benzene Benz(a)anthracene Benzo(b)fluoranthene Benzo(k)fluoranthene Benzo(a)pyrene Chrysene D ibenz(a,h)anthracene Indeno( 1,2,3-c,d)pyrene Constituent Carcinogenic o.r (c) 1.2 (c) r.2 (c) 1.2 (c) 12 (c) 0.12 (c) 4.1 (c) 1.2 (c) Oral CSF, (mg/kg/day)-' and Source 0.1 (c) 0.3e (c) 0.3e (c) 0.3e (c) 3.e (c) 0.03e (c) 4.1 (c) 0.3e (c) Inhalation Notes:l.

California 3.3 Exposure Assessment 3.3.1 Potential Pathways of Exposure In evaluating the potential human health risks posed by a site, it is necessary to identify populations that may potentialiy be exposed to the contaminants present at the site, and to determine the pathways by whitfi these expor.rr.r rnuy occur. Identification of potentially exposed populations requires evaluating human activity and land-use pattems at the site and in the vicinity of the site. 3.3.2 Conceptual Site Model The conceptual site model summarizes understanding and assumptions regarding the nature and extent of site contaminants and their potential migration and exposure pathways for relevant receptors. The conceptual site model presented in Figure 6 identifies contaminant sources and links them to potential receptors through transport mechanisms and exposure pathways. The primary source ofthe contaminant at the proposed Farm Supply property was leaks from the Tank Farm Roadpipeline (depth of pipeline burial about 4 feet). Once the crude oil was released, the new source, also ieferred to as the secondary source, became the subsurface soils and free-phase hydrocarbon on ground water. From these secondary sources, there are three possible mechanisms by which potential ieceptors could be exposed to the site contaminants: 1) volatile constituents might be emitted from the soil into the atmosphere or enclosed spaces, 2) soluble constituents might be leached from the soil or oil into ground water and migrate to potable water sources, and 3) oily soil might be exposed during construCtion. The exposure pathways associated with these scenarios are inhalation, potable water use and for the construction-related exposure inhalation, soil ingestion and dermal lontact (absorption). Given that the weathered crude oil generally lacks volatile and soluble constituents, the volatilization and leaching pathways are not considered effective means of contaminant transPort. The proposed Farm Supply property has been evaluated for impacted surficial (<2feet bgs) soils and surface water or r..rsiiine habitats, and none of these features/conditions has been identified. Therefore, exposure pathways associated with these conditions are incomplete' 3.3.3 Identification ofPopulations presently the proposed Farm Supply property is vacant. The subject site is surrounded by a mixture of cultivated -agiicultural properties and commercial/industrial parcels involved in a variety of manufacturing, warehousing, wholesaling, storage and commercial services. The nearest residential areas are locaied approximately %-mile to the west (west of South Higuera Street) and north (north of Prado Road).

While the Specific Plan has not yet been adopted by the City, the Oraft Specific Plan provides the most likely development scenario for the site. Eigu.. 7 depicis the proposed future development plan for the Airport Area. The Specific plan indicates that the ptopor.d Farm Supply property and all of the surrounding properties will be zoned "services and manufacturing. " Most of the commercial properties in the Airport Area currently receive their water from on-site domestic wells and disposi oith"it waste water in on-site septic systems. The Specific Plan indicates that, once annexed, these properties would be supplied with city water and sewer services, so domestic water supply wells and on-rit. septic systems will become less common' Because some of the .o-r...iul occupants may continu. to ur" wells to supply water to their facilities, this study considers the possibl. "*porurc of workers who may ingest or bathe in ground water containing dissolved hydrocarbons. Given the cunent and proposed future land-uses, there are three human populations that could potentially be exposed to the weathered crude oil. These populations include: . Future on-site commercial workers. Off-site, down-gradient workers in commercial areas. On-siteconstruction/utilityworkers(intrusiveworkers) 3.3.3.

Potential exposures have been assumed to occur over a typical work week for a duration of 25 years. I per USEpA and DTSC requirements, exposure to carcinogenic compounds is assumed to occur for an entire lifetime (24 hours/day, 365 days per year for 70 years). t t_ L ENGLANDGEffiY51EMENVIRONMENTAL ENGINEERING r l I I RISK.BASED CORRECTIVE ACTION PLAN Proposed Farm Supply Property San Luis Obisno Countv. California Page 16 Mav 5. 2000 I 3.3.3.3 On-Site Intrusive Workers In the event of improvements to the property, localized, short-term excavations may occur to install building foundations or conduct repairs. Intrusive workers (e.g., construction workers) are individuals who may contact site constituents during excavation activities performed on-site. Because construction activities have a limited duration, intrusive workers are considered to be exposed for a short duration (20 dayslyear for one year). This group of potential receptors has been included to provide cleanup level calculations which address the possibility of direct soil contact by workers during excavation. 3.3.3.4 Ecological Receptors The weathered crude oil at the proposed Farm Supply property poses no threat to ecological receptors. This conclusion is based on the findings that: l) the residual crude oil consists of high molecular weight, environmentally-immobile (non-volatile and insoluble) hydrocarbons, and 2) the oil is limited to depths of at least 5 feet below ground surface. Therefore, there is no potential exposure pathway by whicfr ecological receptors could come into contact with the weathered crude oil or constituents derived from the oil (no exposure: no risk/hazard). 3.4 Risk Characterization 3.4.1 Summary of Complete Exposure Pathwavs and Relevant Populations As a result of the depth of contamination, the most plausible scenario for direct exposure to oily soil involves activities related to excavation. Since the chemicals of concern possess a very low degree of volatility/solubility, less likely exposure scenarios include: l) volatilization and atmospheric dispersion, 2) volatilization and enclosed-space accumulation, and 3) leaching and ground water transport. The human populations considered are: . Future on-site commercial/industrial workers, . Construction workers involved with excavation of oily soil, and Workers in commercial areas down-gradient ofthe area underlain by oily soil who may drink and/or shower in water containing dissolved hydrocarbons. The exposure pathways include: . Inhalation of air containing vapors ofthe more volatile hydrocarbons or air-bome particulates during excavation and handling of oily soil, L ENGLANDG@SYSTEMENVIRONMENTAL ENGINEERING r- r- t t RISK-BASED CORRECTIVE ACTION PLAN Proposed Farm Supply ProPertY Page 17 Mav 5. 2000San Luis Obispo Countv- California . Direct contact (incidental ingestion and dermal contact) by workers involved in excavation of oily soil, . Direct contact (ingestion and showering) with ground water containing dissolved hydrocarbons by workers in the commercial areas within and near the oily zone. These are considered the worst-case scenarios because (l) excavation workers are likely to have much greater and longer duration exposures than those who may come into casual contact with the excavated oily soil, and (2) commercial/industrial areas lie between the oily zone and residential areas, so workers who may drink water and shower at their places of employment have greater potential for exposure than more distant residents. 3.4.2 Risk-Based Screening Levels Risk-Based Screening Levels (RBSLs) are concentrations in air, water or soil below which the health risks do not exceed iorn. g"tr.rally acceptable level. For carcinogens, the risk level is the risk of excess cancer cases resulting from a lifetime of exposure at a particular concentration. Acceptable risk levels range from one in 10,000 exposed individuals (10-4) to one in 1,000,000 (10")' Under Proposition 65, one excess cancer in 100,000 (l0r) is acceptable. For carcinogens, the RBSLs are based on the general equation: risk : average lifetime intake [mglkg-dayf x potenclfactor [mglkg-day]-' potency factors are from CallEPA sources (Cal/EPA, 1994). Average lifetime intake is calculated using siandard equations and simple analytical modelswhichpredicthydrocarbon compound migration and exposure as described in the RBCA document. For non-carcinogens, RBSLs are based on a "safe dose"(or so-called reference dose) ofthe compound in question. fnat is, a dose below which a receptor is unlikely to experience an adverse effect' The EpA publishes reference doses (RfDs) for many compounds in their Integrated Risk Information System (IRIS) data base and other documents. The average intake of a toxic compound at or below the reference dose indicates the compound does not present a significanthazard. Ahazard quotient (HQ) is defined as the ratio of average intake to reference dose' or: hazard quotient : average intake [mglkg-dayf - reference dose [mglkg-day] The hazard quotient should not exceed 1. The recommended standard parameters and equations for calculating average intake are described in the RBCA document. tL ENGLANDG@SYSTEMENVIRONMENTAL ENGINEERING r I t"RISK-BASED CORRECTIVE ACTION PLAN Proposed Farm Supply PropertY Page 18 Mav 5. 2000San Luis Obispo Countv.

Physical property and exposure parameters forthe PAHs were derived from published USEPA sources ruSEPA; Integrated Risk Information System (IRIS), accessed April 2000). Physical property and exposure parameters forthe C,o-Coo range hydrocarbons (TPH-DRRO) were determinedusing methods recommended by the Massachusetts Department of Environmental Protection (MDEP,1994). The Tier I Risk-Based Screening Levels (RBSLs) are presented in Table 6 for soil and Table 7 for ground water. These are grouped according to carcinogenic effects and non-carcinogenic effects. The ngSLr presented in the tables reflect the most conservative clean-up goal calculated forthe applicable source medium. For instance, with regard to benzene in subsurface soils (Table 6), although RBSL values were calculated for: l) on-site (commercial) volatilization to indoor and outdoor air (RBSLs: 0.07 mgikg and 0.2 mg/I, respectively) and 2) leachate to protect ground water (RBSL : 0.04 mglkg), only the lowest calculated RBSL value (leachate to protect ground water) is presented in the L, ENGLANDG@SYSTEMENVIRONIMENTAL ENGINEERING RISK-BASED CORRECTIVE ACTION PLAN Proposed Farm SuPPIY ProPertY Page 19 Mav 5. 2000 r I San Luis Countv. California table. Similarly, for Table 7, only the most protective RBSL value relevant to a ground water source (potable ground water ingestion) is presented in the table' The soil/ground water RBSLs are based on de minimus (one-in-a-million [10-6]) risk levels for carcinogens and hazard quotient equal to one for non-carcinogens. Appendix B, presents the complete results of the calculations. The volatilization factor and effective diffusion coefficients are calculated using appropriate RBCA equations and the Table B-l parameters. These are used along with the exposure parameters to calculate the RBSLs. Table 6 Tier I Risk-Based Screening Levels for Subsurface Soil Tier I values represent source zone which, ii left in will not cause an exceedance of applicable hazard limits.

Foithe remaining carcinogens, the RBSLs are equal to or exceed the maximum measured site concentration indicating that the risk of excess cancer cases resulting from a lifetime of exposure is equal to or less than one-in-a-million (l0n). The only maximum concentration that approaches the RBSL is benzene under the "soil leaching to ground wateC' scenario' The absence of benzene in down-gradient monitoring wells attests to the conservatism of treating maximum detected concentrations as "representative" of site conditions. In light of the preceding, and considering that the RBCATieT I evaluation incorporates a number of comlound.ing protectiie assumptions, ii may be concluded that the contamination does not pose a threat to current users of the property, future commercial/industrial occupants, intrusive construction workers, or down-gradient workers using ground water' However, during construction, it is possible that deep excavations could encounter oil-stained soils' To address this possible scenario, a cbntingency plan for encountering crude oil impacted soil has been prepared and is attached as Appendix B. this contingency plan includes instructions for initial actions and notification, personal protection and material handling. In reviewing the results of this risk characterization, it should be kept in mind that the potential risks estimated in this analysis are based on a series of health-protective assumptions regarding exposure and toxicity, including worst-case concentrations. These assumptions have been made to ensure that potential risks are nof underestimated. Any actual risks associated with the site are expected to be much less than those estimated in this analysis, and, in fact, may be zero. 4.0 SUMMARY AND CONCLUSIONS This report presents a risk-based corrective action (RBCA) evaluation of the proposed Farm Supply property (ApN 076-351-033) located in San Luis Obispo County, Califomia (Figure l). Soil and jro.rla *ater underlying the south margin of the property are impacted by releases of crude oil from I pipeline beneath fanf farm Road. The extentbf oily soil, free oil on ground water and dissolved trydiocarbons in ground water have been delineated and characterized in several studies. The objective of this corrective action plan is to evaluate the site assessment data and recommend an appropriate response based on the protection of human health and the environment' The subject property is currently vacant, but historically has been used for agricultural purposes' The city of San t-uis ouispo,s General plan Land Use Element calls for the area (the property is part of the f t_ t" ENGLANDG@SYSTEMENVIRONIV]ENTAL ENGINEERING r- t ['RISK.BASED CORRECTIVE ACTION PLAN Proposed San Luis Farm Supply ProPertY Page22 Mav 5, 2000ObispoCalifornia .,Airport Area") to be eventually annexed into the city. The Airport Area Specific Plan indicates that the subject site and all ofthe surrounding properties will be zoned "services and manufacturing'" The nearest residential areas are located approximatery %-mile to the west (west of South Higuera Street) and north (north of Prado Road). Site assessment data indicate that the oil in the subsurface is comprised of high-molecular weight compounds with very low concentrations of polynuclear aromatic compounds and BTEX' The crude oil extends onto the iropor"d Farm Supply proierty for a distance of l5 to I l0 feet, covering an area of about 0.6-acre. consistent with an ori-rit"'u.r.ied pipeline source, detectable concentrations of petroleum hydrocarbons beneath the property are limited to depths deeper than 5 feet and shallower than 2l feet bgs (Earth systems Environme ntal, rggT). TpH is occasionally detected in ground water samples from monitoring wells situated downigradient of the crude oil impacted area (up to 3 mg/l), but BTEX and pNAs urJrarely detected. on the few occasions when these have been detected, their concentrations have been very low' The subject property is located in the San Luis valley, a relatively level, narrow, alluvium-filled basin' The alluvium, whichconsists of approximately 160 feet of laterally discontinuou_s-interbeds of gravel, sand, silt and clay, cornpris"s the major grou,,d water aquifer in the San Luis Obispo ground water basin. In the site vicinity, poor quuiity,i.-i-confined ground water has been measured at depths ranging from 7 to more tlan :o reit ueto* ground surface. The potentiometric surface slopes to the southwest (mean flow direction:S65oW; wltn a gradient ranging from approximately 0'002 to 0'008 fooVfoot (Figure 3). The RBCA evaluation follows the traditional four-step process defined by the National Academy of Sciences and the usEPA for developing risk assessments' These steps included: . Evaluation of available data to identiff chemical constituents of potential concern; . An exposure assessmentto identiff scenarios underwhich humanpopulations may be exposed; . A toxicity assessment, in which the toxicities ofconstituents ofpotential concern are evaluated, and toxicity indices are identified for use in characterizing potential risk; and . The calculation of appropriate (generic) risk-based screening levels (RBSLs - media concentrations which are protective of human health and the environment)' Based on the results of the data evaluation, the RBCA evaluation focused on three classes of hydrocarbon comPounds : . Aromatic compounds (i.e., benzene, toluene, ethylbenzene, and xylenes); it- t" ENGLANDG@SYSTEMENVIRONMENTAL ENGINEERING I r I L RISK.BASED CORRECTIVE ACTION PLAN Proposed Farm Supply ProPenY San Luis Obisoo Countv. California Page23 Mav 5. 2000 . PAHs including acenaphthene, benzo(a)anthracene, benzo(b)fluoranthene, benzo(k)- fluoranthene, benzo(g,h,i)perylene, benzo(a)pyrene, chrysene, dibenzo(a,h)anthracene, fluoranthene, fluorene, indeno(1,2,3-c,d)pyrene, phenanthrene, and pyrene; and . TPHs including diesel/residual range organics' Environmental media considered in the RBCA evaluation included air, subsurface soils, and ground water. In evaluating these media, the following human exposure scenarios were considered: . Future on-site commerciaVindustrial workers who may be exposed to volatile organic constituents emitted from the soil and ground water into the atmosphere or into enclosed spaces; . An on-site utility worker who may be exposed to on-site soils during excavation or utility installation, as well as to airborne fugitive dust and volatile organic constituents; and . On- or off-site workers who may be exposed to ground water from wells that may be installed down-gradient of the site. Safe exposure levels and other toxicity information were identified for each of the constituents evaluated in the RBCA analysis. Sources of this information included current DTSC and USEPA guidance. In addition, surrogate compounds were selected to characterize the potential toxicity of fetroleum hydrocarbon mixtures. This approach is consistent with recent guidance developed by the MDEP (1994). The results of the RBCA evaluation indicate that maximum concentrations of the site constituents of concern in subsurface soil and ground water do not exceed the risk-based screening levels (RBSLs). Therefore, the sites do not pose threats to current or future commercial/industrial users of the properties, intrusive construction workers, or down-gradient workers using ground water. Under the ronditionr.onsidered herein, no corrective action is required to reduce risk/hazardto acceptable levels. In reviewing the results ofthis evaluation, it should be recognized that the assumptions and approaches used herein were designed to ensure that potential risks were not underestimated. Any actual risks associated with the property are likely to be much less than estimated in this analysis, and may, in fact, be zero. [n the event that future development results in significant changes to site grades in the vicinity of the soil impacts, this risk evaluation should be updated to reflect the changed conditions. During construction, it is possible that deep excavations could encounter oil-stained soils. To address this possible scenario, a contingency plan for encountering crude oil impacted soil has been prepared and ls attached as Appendix B. This contingency plan includes instructions for initial actions and notification, personal protection and material handling. t- L" ENGLANDG@SYSTEMENVIRONIV]ENTAL ENGINEERING RISK.BASED CORRECTIVE ACTION PLAN Proposed Farm Supply PropertY Page24 Mav 5.2000San Luis Obispo Countv.

California 1.0 INTRODUCTION AND OBJECTIVES Crude oil leakage from a pipeline serving Unocal's San Luis Obispo Tank Farm resulted in contamination of soil and ground water underlying Tank Farm Road and adjacent areas. Detailed assessments of the contamination have established that the crude oil does not pose a threat to human health or the environment. Even the risk to utility workers, the only group who may potentially be exposed to the crude oil during excavation, was studied and shown to be insignificant. Since the poiential exists forcrude oil-impacted soil to be exposed duringfuture construction, arepresentative of tn. City of San Luis Obispo requested that a generalized Health and Safety Plan (HASP) be prepared io provide contractors with a source of information on health and safety issues and recommended soil handling practices. It is the objective of this document to: . Pro vide appropriately trained, licensedcontractors with chemi calhazardinformation for the crude oil impacted soil. This information was developed with the intent that it be attached as an addendum to a contractor's sile/task-specijic HASP,thus aiding in the protection of the health, safety and welfare of workers who may potentially encounter oily soil; . Provide contractors with the information necessary to fulfiII State and Federal hazatd communication (HAZCOM) requirements for workers who may potentially be exposed to oily soil; and . Minimizeany further threat to the environment due to inappropriate handling of oily soil, if encountered. 2.0 LIMITATIONS The information contained in this HASP is provided for guidance purposes only and is not intended as a substitute for the development of a site/activity-specific HASP which should be prepared by any entity conducting work in any area. Firms requiring workers to excavate within the described vicinity must ensure that: 1) the work is conducted in accordance with all Federal, State, County and City requirements; and 2) their employees are working under, and in accordance with, the firm's Injury&IllnessPreventionProgram(IIPP), Codes of Safe Practice, HazatdCommunicationProgram (HAZCOM), and Emergency Response Plan. These health and safety programs, codes and plans are the minimum required of an excavation contractor by CaI/OSHA pursuant to Title 8 of the California Code of Regulaiions. Whereas the Codes, IIPP andHAZCOM documents are task specific (site generic), theEmergency Response Plan is a site specific document. We recommend that this HASP be included as an addendum to a site-speciftc heatth and safety document (i.e., Emergency Response Plan). t_ t t_ ENGLANDG@SYSTEMENVIRONMENTAL ENGINEERING I I HEALTH & SAFETY PLAN Unocal Tank Farm Road Pipeline Leak Site Page2 May 5, 2000SanLuis Obisoo. California This HASp focuses upon chemical and ancillary hazards associated with the oily soil and material handling procedures in the event such soil is encountered. Implementation of the procedures contained herein are at the sole discretion of the entity conducting the excavation work. It does not address any other health and safety issues which may be related to an entities' or individual's area of expertise and contains no guidance regarding excavation procedures or techniques. England & Associates will not be responsible forimplementationofthis HASP and strongly suggests thal appropriate safety professionals (i.e., industrial hygienist) prepare and implement a safety p.og.u* which directiy udd..rt.r the work to be preformed (i.e., a site/activity-specific HASP). 3.0 BACKGROUND Approximately 60 years ago, a release of heavy crude oil from Unocal's pipeline beneath Tank Farm noaa in San t-uis CiUispo -ounty resulted in crude oil contamination of soil and ground water under the road and adjacenf property. The extent of oily soil, free oil on ground water and dissolved hydrocarbons inground *ut"r have been delineated in several studies (Brown and Caldwell, 1988, l919;Dames & Moore (D&M), 1990; Earth Systems Consultants (ESC), 1996a,1996b). Recent investigations by Earth Systems Consultants have improved the definition of the area in which hydrocarbon concentration exceeds 100 mg/kg in the soil within the San Luis obispo City limits 1ESC, 1996a,1996b). Figure I (attached) shows the site location and the approximate extent of impacted soil. The top of oily soil ranges from 8 feet deep near Tank Farm Road to 15 feet deep near the northern and southern plume margins (ESC, 1996a, lgg6b,l996c). Soil impacted by crude oil typically displays an olive gray color - as opposed to brown which is common elsewhere. The impacted soil g"n"rutty has a discernable hydrocarbon odor and heavily impacted areas may exhibit small drops of dark brown oil in the soil Pores. 3.1 Chemical Hazard Risk is a function of toxicity and exposure. For a toxic substance to pose a threat, the potential for exposure must exist. If there is no probable route of exposure, there is no risk. Potential routes of .*potut. include ingestion, inhalation, dermal absorption and injection. Crude oil is a naturally-occurring (i.e., unrefined), complex liquid consisting almost entirely of hydrocarbons (i.e., varying mixtures of the elements hydrogen and curbon (hydrocarbon). The pirysical properties and chemical composition (toxicity) of crude oil vary markedly, depending on itr- rour... The primary constituents of crude oil fall into three major categories: paraffins, naphthenes, and aromatics. Many crude oil components, such as paraffins and naphthenes, are ENGLANDG@SYSTEMENVIRONIV]ENTAL ENGI NEERING t'- I r- t HEALTH & SAFETY PLAN Unocal Tank Farm Road Pipeline Leak Site Page 3 May 5, 2000SanLuis Obispo. Califomia generally not considered to be highly toxic (Amdur et al., I99l; Clayton and Clayton, 1981) and are iot typically included as chemicals of concern in assessments of health hazatd. The constituents of primary concern for hazardassessment are contained in the aromatic fraction. The most toxic known compounds found in the aromatic fraction are benzene and the suspected carcinogenic polynuclear aromatic hydrocarbon (PAH) compounds (carcinogens are chemicals thoughicapuUt. of .uusing cancer if administered in large or long-lasting doses). Noncarcinogenic comfounds that may also be of concern include toluene, ethylbenzene, xylenes, naphthalene, and othei noncarcinogenic pAH compounds. In addition to their potential toxic effects, benzene, toluene, ethyl benzene and xylett"rlntex) compounds are of concern because of their volatility and mobility in the environment, properties that increase the likelihood of exposure. BTEX compounds have been detected only infrequently in soil, and where they have been detected, their concentrations have been very low (BTEX: <0.04, <0.18, <0.07 and <0.34 mg/kg) (Dames & Moore (D&M), 1990). A more recent investigation found no detectable BTEX in ten samples with measurable crude oil concentrations (Earth Systems Consultants, 1996)' These very low concentrations are not considered sufficient to pose significant health and/or safety hazards to utility workers (England & Associates, 1996a). Air quality monitoring for volatile hydrocarbons during construction is not necessary. Monitoring for air quality concems unrelated to the crude oil problem (i.e., oxygen deficiency, eti.) are the responsibility of the entity conducting the work' Of eight soil samples analyzed for PAHs, twelve PAH compounds were detected (D&M, 1990)' Seven of these ur. ,urp""ied human carcinogens and five are not. PAHs have very low vapor pressures and adsorb strongly to soil. Therefore, inhalation of vapors is not a likely route of !*poru.". potential routes of "*por.rre to PAHs involve ingestion of soil, absorption through the skin (dermal absorption), and injection (dirty cuts or puncture wounds). Although it has been shown that the pAH concentrations in soil are too low to constitute a significant health threat, safe work practices and good personal hygiene can substantially reduce the potential for even low levels of exposure to PAHs.

The MSDS is verT broad to covers a wide range of crude oils and is, therefore, very con;ervative. Furthermore, the crude oil at the Tank Farm Road site has been in the ground for at least 60 years and has undergone extensive weathering. The effects of weathering are most profound on the low-molecutar weigtrt fraction of the petroleum, selectively removing/reducing the more volatile and soluble constituents. Therefore, the weathered crude oil does not possess the flammability hazards described in the MSDS' 3.2 Human Exposure Hazard Analysis A Health Risk Assessment (HRA [England & Associates; 1996a]) was conducted to address the potential for adverse health affects as a result of worker exposure to oily soil during utility construction. The HRA considered the potential threats to worker health associated with inhalation ofvapors and air-borne particulates anddirect contact (incidental ingestion and dermal contact) with oily soil during construction. The risk appraisal assumed conservatively high levels of exposure (worst-case soil concentrations) for ten (tO) aays (much longer than is typically required for utility installation) so as to not underestimate the threat' The results of the HRA indicate that the site is safe for utility workers under the conditions considered. Both potential carcinogenic risk and noncarcinogenic hazardare considered acceptable under Califomia Department ofloxic Substance Control and United States Environmental protection Agency guidelines. It is important to note that the assumptions and approaches used in developing the HRi were designed to ensure that potential risks were not underestimated' For example, risk assessments typicalty utilize average concentrations to estimate chronic risks associated with long-term exposures, however, the maximum reported concentrations of hydrocarbons in soil Jere used in trre calculation of potential risks. Any actual risks associated with the Tank Farm Road pipeline site are likely to be much less than estimated inthe HRA analysis, and may, in fact, be zero.

Be prepared to provide an accurate work area location (i.e., nearby intersections, property address or map page and grid location) and description of the work being performed. Unocal may, at its discretion, provide a technician to document the conditions encountered and oversee soil segregation and stockpiling. Establish Designated Work Areas.- Access to work areas srurounding an excavation exposing oily soil and the oily soil stock pile should be controlled by erecting temporary barriers. Only authorized workers wearing upp.ou.d personal protective equipment shall be permitted within the designated work area. Eating, drinking and smoking should be discouraged within the designated work area. personal protective Equipment: Although the health risk assessment demonstrated that the potential for adverse health effects as a result of construction in the oily soil area is negligible, pe.so.ral protective measures should be implemented to minimize contact with oily material. To achieve tiris goal all work shall be conducted in Level D personal protective equipment (PPE). Level D PPE includes: long pants ancl long-sleeved shirts, steel-toed boots, gloves, hard hat and safety glasses. personal Hygiene: Toavoid accidently ingesting oily soil, eating, drinking and smoking should be discouraged within the designated work area. Oily soil may be transferred to food by dirty hands or air-borne dust ,nuy r"ttl. on food containers (i.e., soda cans) resulting in unintentional ingestion. Prior to eating, drinking or smoking and at the end of the work day, thoroughly wash hands andface with soaP and water- Minimize Exposure: To the extent possible, minimize physical entry into any trench or pit exposing oily soil. Material Handting: Minimize the amount of oily soil excavated. Excavate only what is necessary to complete the task at hand. Visibly oily soil should be stockpiled separately from other excavated material. The material should be stockpiled onto plastic sheeting and covered by securely anchored plastic sheeting. The purpose of covering the oily soil is to minimize the potential for human contact, not to ,oppt.slrupors (since volatile constituents are not present). Therefore, if the oily soil is to be moved later the same day, covering may be unnecessary. Oily soil should not be placed back into any excavation without written authorization. ENGLANDG@SYSTEMENVIRONIV]ENTAL ENGINEERING r- I I HEALTH & SAFETY PLAN Unocal Tank Farm Road Pipeline Leak Site Page 6 Mav 5. 2000SanLuis Obisoo. California 5.0 OTHER REQUIRED PLANS As was pointed out previously, the purpose of this document is to provide chemical hazard and materialiandling information for parties excavating within the area of impacted soil. The document is not intended as a substitute for the development of a site/activity-specific HASP as required by CallOSHA. It is strongly recommended that any entity considering excavation in any area prepare and implement a health and safety plan that addresses the physical hazards associated with the specific work to be performed (task-specific health and safety plan). Task-specific health and safety pians should include site-specific pre-emergency planning (Emergency Response Plan) including, but not limited to: personnel roles, lines of authority and communication; emergency contacts and phone numbers; em€rgency alerting and notifi cation procedures; route to the nearest hosPital; list of required safety and first aid equipment (i.e., fire extinguishers); and other information as appropriate for the task and site. This document should be provided to the City/County of San Luis Obispo agency(ies) responsible for issuing construction/excavation permits. The City/County should provide copies of this document to contractors applying for excavation permits in the affected area. Moreover, contractors bidding on public works projects should be provided a copy of this document together with the other bid documents and the bid documents should be written so as to require contractors to include this plan in their task/project-specific health and safety plan. 6.0 SELECTED REFERENCES Admur, M.O., Doull, J., and Klaasen, C.D., (Eds.) 1991, Cassarett and Doull's Toxicology: The Basic Science of Poisons,4th ed.

This HASP will be implemented by Specialty Construction, lnc. (SCl), and will be enforced upon SCI's employees and contractors hired by and working under the direction of SCl. This HASp has been developed by Specialty Construction, lnc. in accordance with Title g of the California Code of Regulations, Section 3203 (T8 CCR 3203, Cal OSHA) for the lnjury and lllness prevention program (llPP), and the requirements set by OHSA Occupational Health and Safety Standards CFR 29, subpart 1910.120(bX4). This HASP has been developed as a working document to be continually utilized and updated during work activities at the work location described herein. A publication of this size cannot encompass all of the safety procedures for every situation or condition, but does provide general information and guidelines that, when followed, should reduce accidents and control losses. lf situations or additional questions arise which are not covered by this HASP, they should be brought to the attention of the Project Manager, the Site Safety Officer (SSO)' HES Manager or another appropriate supervisor who will seek clarification. 1.1 DESCRIPTION OF PROJECT SITE The proposed construction activities are scheduled to be completed along Tank Farm Road. The excavation activities are required to install a section of the new sewer line' Soil excavation activities at the work area have indicated the presence of petroleum hydrocarbon- containing soil, requiring appropriate health and safety measure to protection workers and the general public. 1.2 PROJECT ACTIVITIES COVERED UNDER THIS HASP This HASp is applicable to SCI employees completing excavation and management of contaminated soil and water during the course of the sewer line construction activities' Should site-specific conditions warrant (e.g., additional chemical exposure or significant change in physical site configuration), or activities beyond those described above are to be performed, a revision to this HASP will be prepared and implemented at the Project Site. No additional activity will be performed until any revisions to this HASP have been communicated to the project team and if needed appropriately trained and qualified personnel are available with the appropriate resources to perform the task. -1- SCI Health and Safety Plan Project No. 218102 August 2018 e Briefing site personnel before work begins each day regarding the contents of this HASP and authorized revisions of this HASP, including potential hazards, safe work practices, required PPE, and emergency procedures.e Maintaining a copy of this HASP at the site.. Ensuring that specified PPE is available and, when appropriate, worn by personnel working at the site.o Controlling access to the exclusion zone and/or work areas as defined.. Establishing emergency evacuation routes and designated meeting places in advance of each work activity and communicating this information during the daily safety briefing.. Coordinating response to emergencies at the site, directing evacuation, or summoning emergency assistance, if necessary.. Conducting site walk-through inspections on a regular basis.. Maintaining field documentation, including daily safety briefing attendance sheets, air monitoring data, and site walk-through inspection results.o Notifying the Project Manager immediately regarding any health and safety problems or emergencies.. Completing exposure and perimeter air monitoring activities. NOTE: Notify the HES Manager of changes in site conditions or in the scope of field activities. 2.3 HES MANAGER The HES Manager will review, and authorize this HASP and any subsequent revisions to the plan. The HES Manager will assist with the implementation of the HASP and provide project support on health and safety issues. The HES Manager will consult with the Project Manager if revision of this HASP is required. The HES Manager will verify field personnel training, required medical surveillance, and respirator fit test requirements. The HES Manager will advise the Project Manager regarding industrial hygiene concerns, interpretation, and evaluation of analytical exposure data, and other safety related issues, as needed. Additionally, the HES Manager may complete the exposure and perimeter air monitoring activities and act as the point of contact for air monitoring data and real-time results to regulatory agencies and site personnel. 2.4 SITE SAFEW OFFICER The SSO will implement this HASP in the field. The SSO authority and responsibilities include, but are not limited to, the following: . lnforming site personnel before work begins each day of the contents of this HASP and authorized revisions of this HASP, including potential work area hazards, safe work practices, required PPE, and emergency procedures.. Maintaining a copy of this HASP at the site.. Ensuring that specified PPE is available and, when appropriate, worn by personnel working at the site.. Controlling access to the exclusion zone and/or work areas as defined. -J- SCI Health and Safety Plan Project No. 218102 August 201 8 3.0 GENERAL SITE SAFETY PROCEDURES AND REQUIREMENTS 3.1 GENERAL SITE WORK HAZARD ANALYSIS The primary health hazards associated with the planned project activities are chemical and physical in nature. During the excavation and field activities, exposure to potentially hazardous compounds through inhalation, ingestion, and dermal absorption is of concern. Chemical and physical hazards are further detailed in Sections 4.0 and 5.0, respectively, of this HASP. The procedures and precautions presented below are general and apply to all SCI supervised personnel regardless of the task to be performed. . Prior to the initiation of a new project a Job Safety Analysis (JSA) will be completed by site personnel. The JSA will identify the potential hazards that may exist during the field activities, and will include a sequence of the basic job steps, identifying the potential hazards, and the steps to prevent the identified hazard. The JSA is to be signed by all personnel on the work team.. Daily Safety Tail Gate meeting. The meeting will focus on the specific task(s) to be performed that day, a review of the JSA and a safety topic for the day.o All personnel will read the HASP and indicate understanding and compliance of HASP requirements by signature in this HASP.. Any unsafe condition or safety concern should be brought to the attention of the Site foreman, the SSO, or SCI staff. lf there is a change of the SSO during the course of the project, the change will be addressed during the daily safety meeting.. Personnel will initially be required to wear Level D PPE. Level D protection at a minimum consists of long pants, long-sleeved shirt, steel-toe boots, hardhat, personal H2S monitor and approved safety glasses.. lf potential exposure to volatile organic compounds (VOCs) become a concern during excavation activities, PPE will be upgraded an adequate level of protection determined by the SSO on-site. Level D with the addition of Tyveks and a half-face respirators will be considered depending on the results of the real{ime air monitoring for worker exposure. 3.2 SMOKING Smoking is permitted only in designated areas within the Project Site. Smoking areas will be designated by SCI at the beginning of the project activities. tr SCI Health and Safety Plan Project No. 218102 August 201 8 5.0 PHYSICAL HAZARDS AND REQUIRED CONTROL MEASURES Physical hazards associated with Project Site activities include, but are not limited to, the following: o Fire (one ABC rated fire extinguisher must be available at alltimes);. Local and site area traffic near the Project Site;. Foot traffic and cyclists on the Railroad Safety Trail;o Excessive noise; and. Wildlife including snakes, bees, ticks, yellow jackets, wasps, spiders, etc. The following table of Potential Physical Hazards and required Control Measures is a generalized table of possible physical hazards and their control measures. Some situations may arise where this table will be useful; however, it anticipated that some of these situations will not be required for this project. POTENTIAL PHYSICAL HAZARDS AND REQUIRED CONTROL MEASURES Potential Physical Hazard Reguired Gontrol Measure(S) Objects striking head Hard hats will be worn during construction, maintenance, and heavy equipment operations. When there is a potential for overhead hazards, hard hats will be worn. Flying particulates or objects Safety glasses and/or face shields will be worn during construction, maintenance, and sampling activities. When there is a potential for flying projectiles, such as hand tools, safety glasses will be worn. Foot hazards Steel-toed boots will be worn at all times while on site. Heat afflictions Observe work/rest cycles for measured temperature conditions and follow Heat lllness Prevention Plan (Appendix E). Mechanical systems and moving equipment All cleaning, repairing, and servicing of machines and equipment will be conducted in accordance with Title 8, California Code of Regulations (CCR), Sections 3314 and 3328, and applicable Federal Occupational Safety and Health Administration (OSHA) regulations. Machine guards will be used where appropriate to provide maximum protection for field employees. Access to areas where moving machines and machines with moving parts are located will be controlled and limited to those individuals experienced with those machines or who have received proper safety instruction with respect to the machinery. All major installations or major repair to mechanical systems will be conducted only by a qualified mechanical contractor. Only qualified personnel will make minor adjustments to those systems with' prior approval by the Project Manager. Copies of the applicable operation and maintenance manual and manufacturer's operations manuals will be available on site at all times. Loose, ragged, or poorly fitted clothing, dangling jewelry, or rings will not be worn when working around equipment or machinery. Any of these items could become snagged in moving equipment and result in serious injury. All long hair will be contained to prevent it from getting caught in moving equipment. Air compressors and pumps are started automatically under some conditions. This equipment will be electrically disconnected and locked out before service or repair. (- -7 - SCI Health and Safety Plan Project No. 218102 August 2018 Potential Physical Hazacd Required Gontrol Measure(S) entering the excavating equipment work area will wear an orange safetyvest. Do not stand alongside, behind, or in the operating area of any operating excavating equipment. Be aware of the tail and boom swing- radius of track hoes, cranes, and other center pivoting equipment. Also be aware of pinch points on articulated equipment such as front-end loaders. Vehicles All vehicles will be parked away from operating excavating equipment areas unless necessary to load or unload equipment or samples. No vehicle will enter any operating excavating equipment area without first notiffing all excavating equipment operators. Any vehicles in the operating excavating equipment area will have a suitable warning flag or strobe attached to the vehicle. Overhead utility lines Maintain a minimum of 50 feet of clearance between any field equipment and high voltage lines; lines carrying more than 50,000 volts require additional clearance; electrical archazard is increased during high humidity or rainy conditions Manuallifting During any manual material handling tasks, personnel are to lift with the force of the load suspended on their legs and not their backs. Several persons may be needed to lift or handle heavy equipment. Weather conditions Severe thunderstorms, Iightning, and local flooding may occur during the rainy season. ln case of severe weather, halt all operations and move indoors or into the cab of a truck as soon as possible. Avoid ravines and small arroyos due to the possibility of flooding during heavy rainfall. lf there is lightning activity in the vicinity, the SSO at the site will decide when to halt site activities. A rule of thumb is that if you can see lightning or hear thunder you are close enough to be struck by lightning. Compressed gas cylinders Such vessels will be secured and used with the manufacturer's recommended valves and fittings. Unused cylinders will be secured and capped. All cylinders will be identified or labeled. Flammable gasses will be grounded and bonded. Vehicle traffic When conducting field activities in roads, streets, and parking lots, mark the area with safety cones, wear orange traffic vests, and turn on the vehicle's emergency flashers. Safety cones should taper gradually and allow cars to change lanes or merge easily. Safety cones should extend past the work area. One field employee should act as an observer and watch the traffic and act as a buddy to the other field employee. Shoring of Excavations An H&S permit from CAUOSHA is required when personnel enter an excavation or trench 5 feet deep or greater. Only a competent and adequately trained inspector will perform excavation and trenching activities. All excavation, trenching and shoring activities will be performed accordingto subcontractor Standard Operating Procedures. Evaluation of any excavation by SCI's supervising competent person may require installation of positive retention shoring devices. Each excavation will be evaluated throughout its construction and duration for need of such retention devices. Exposure to VOCs or airborne chemicals Personal exposure monitoring to benzene and VOCs will be conducted in the work zone. Work activities will cease if total VOCs are indicate in excess of50 ppm. Off-site migration of airborne chemical hazards or nuisance odors Work zone perimeter air monitoring will be conducted to monitor and document ambient concentrations of total VOCs. Work activities will cease at 50 ppm, agency notification will occur if off-site migration exceeds 100 ppm. -9- SCI Health and SafetY Plan Project No. 218102 August 201 8 Additionally, the SSO will utilize employee observations and professionaljudgment as a basis of the need for such monitoring. 5.2 WILDLIFE HAZARDS The project Site is located within an urban area and wildlife hazards are not anticipated in the work area. However, if wildlife hazards are encountered (potentially loose dogs or swarming bees) project activities will be temporarily ceased and the site secured and reevaluated for safe working conditions. 5.3 CONFTNED SPACE HAZARDS A recognized Confined Space (CS) is define by Ca|/OSHA, CCR Title 8, Section 5157 as an enclosure or work area that meets all of the following criteria: o ls not designed for continuous human occupancy; andr Has limited or restricted means of entry and exit; ando ls large enough to bodily enter and perform assigned work activities' Some examples of recognized CS areas include vessels, pipelines, bins, box-like compartments, underground vaults, pits, trenches, excavations and tunnels. Opentopped vaults, pits, and tunnels of more than four feet in depth are also included. Confined spaces are normally considered to be enclosures with known or potential hazards and are restricted means of entrance or exit. Additionally, any CS may be considered a Permit-Required CS (PRCS) if it meets anv one of the following conditions: . The CS has the potentialfor a hazardous atmosphere; or. The CS contains a material that has the potential for engulfing and suffocating the entrant; or. The CS has an internal configuration that could trap and asphyxiate or suffocate by inwardly converging walls or a floor which slopes downward and tappers; orr The CS has any other recognized serious safety or health hazard' Some examples of recognized PRCS areas include silos, oil or chemical tanks, trenches and excavations with chemical hazards, or any CS with an elevated temperature that may cause heat illness. lf work activities are to be completed in a recognized CS or PRCS area a written Confined Space Entry Program will be required, including air monitoring and an emergency rescue and evacuation plan. Where the employer can prove that the only hazard present in a CS is an actual or potential atmospherichazard that can be controlled through ventilation alone, the employer can use alternate procedures. This means that a permit is not required for entry, rescue arrangements do not have to be made, and no attendant is required. lt is extremely important that any employer who attempts to use alternate entry procedures follow the requirements of CFR 1910.146 paragraph (c)(5), and CCR Title 8, Section 5157, paragraph (cXs). -11 - SCI Health and SafetY Plan Project No. 218102 August 2018 7.0 DESIGNATED WORK AREAS Access to work areas will be in accordance with the daily JSA and will be controlled by the SSO and/or SCI Foreman. The use of an exclusion zone will be established on an as- needed basis at each work location within the Project Site. Access to the work area will be monitored as the site activities proceed and if warranted in the professional judgment of the SSO or contractor performing the work, may be upgraded to include: r An exclusion zone will be created around the work atea or equipment; o The exclusion zone will consist of delineators and / or caution tape, and absolutely no unauthorized personnel will be allowed within the exclusion zone; o ppE as designated in Section 6.0 will be required and no eating, drinking, or smoking shall be allowed in designated work areas; o Exclusion zones will be maintained and relocated as necessary; and . caution tape will be used to restrict access, where necessary. 8.0 DECONTAMINATION PROCEDURES lf personnel decontamination is necessary, personnel will ensure that fumes and dust are not generated and chemically-resistant gloves are worn to protect against dermal exposure. Decontamination will include: r The SSO will evaluate the need for portable eye wash stations. lf needed, the will be available in the site vehicles; . Removal, containment and disposal of PPE; . General hygiene: keeping hands clean and eliminating handto-mouth actions; . No smoking, eating or drinking will collecting samples; and o Equipment decontamination will be performed between sample locations to eliminate the possibility of sample cross contamination. 9.0 DISPOSAL PROCEDURES Waste disposal will be evaluated by the SSO and SCI Foreman or Project Manager, if encountered. Contaminated soilwill be segregated from clean soil and characterized for proper off-site disposal. Waste manifests will be utilized to track the shipment of soil otf-site to the designated disposal facilitY. - 13 - SCI Health and SafetY Plan Project No. 218102 August 2018 evacuation instructions, via the site emergency radio if necessary, to site personnel regarding the actual site conditions. 11.2 HOSPITAL LOCATION AND DIRECTIONS The nearest medical services to the Project Site are located at either French Hospital Medical Center, approximately 5 miles to the north of the Project Site on Johnson Avenue, or Sierra Vista Regional Medical Center, approximately 4.4 miles to the north of the Project Site on Murray Ave. The address, phone number and directions are provided below: French Hospital Medical Center 1911 JohnsonAvenue San Luis Obispo, CA 93401 Phone: (831) 534-5353\/1r- obrsfro#sxefut"o-ry"r9 o {L9 t II 5l rom&& -15- SCI Health and Safety Plan Project No. 218102 August 2018 permit will be required; and all potential fires are source or flammable materials will be reported to the SSO or SCI Foremen immediately. 11.4 MATERIAL SPILLS All field personnel are authorized to contain hazardous material spills by immediate diking and cleanup only if the spill was created by project operations. Equipment and work areas will be maintained in clean, proper working order. Caution will be exercised during field activities to prevent spilling materials generated during field activities. ln the event that project generated materials are spilled, response actions must be initiated by first contacting the SSO. Proper PPE and spill cleanup materials will be available onsite' Hazardous materials spills will be contained by immediate diking using spill clean-up materials present onsite. Containment of spills by field personnel during field operations is limited to those materials generated during field work performed by project personnel, including soil sampling. Project personnel are not authorized nor are they trained for hazardous materials response to contain spills of other materials onsite. Field personnel will report all hazardous material spills to the SSO or SCI Foremen immediately. The project SSO, SCI Project Manager, or SCI Forman will make agency notification and initiate outside spill response services as appropriate. 11.5 EARTHQUAKE Any personnel inside a building during an earthquake should remain indoors and take cover under a desk, in a doorway, or against an inside wall. Personnel should stay away from windows and light fixtures. lf outdoors, personnel should move to an open, clear area away from buildings, tanks, heavy equipment, aboveground piping, and power lines. 11.6 EMERGENCY MEDICAL TREATMENT AND FIRST AID ln the event of personal injury or illness, professional medical assistance should be summoned as appropriate. All SCI Personnel will be trained in First Aid and adult CPR. Specific instructions for administering First Aid and CPR will be in accordance with the First Aid and CPR instruction book located within the on-sight First Aid kit. Professional ambulance services will be used to provide prompt medical attention and transportation when required. 11.7 EMERGENCY ACTION PLAN SCI's emergency action plan (EAP) will be developed on a daily basis and maintained onsite during work activities. The EAP will include primary and secondary evacuation points, resources to procure upon evacuation (i.e., sign-in sheet for head count), and emergency contact information. EAPs will generally be included in the daily JSA documents. Minimum Requirements The following are the minimum requirements for an emergency action plan: e Emergency escape procedures and escape route assignments o Emergency alarms . Procedure for notifying emergency services -17 - SCI Health and Safety Plan Project No. 218102 August 201 8 APPENDIX A SAFETY DOCUMENTATION - 19 - SCI Health and Safety Plan Project No. 218102 August 20't8 HEAT ILLNESS PREVENTION PLAN Temperature Summary Table Temperature ("F)Required Action 80 Shade is on-site and available. 85 Shade is up at the start of the day until end of shift. 90 lce is available to keep drinking water cool. Monitor availability of drinking water and replenish as needed. 95 High-Heat Procedures in place (see below). lncrease water breaks Provision of Water The Site Safety Officer (SSO) will bring at least 1 case of bottled drinking water, or one S-gallon cooler of drinking water to the Project Site, so that at least 2 quarts per employee are available at the start of the shift. The SSO will bring one box of disposable cups (if needed) and the necessary cup dispensers to ensure that enough disposable cups are made available for each worker and are kept clean until used. As part of replenishment procedures, the SSO will check the water level of all containers every 2-3 hours and more frequently when the temperature exceeds 90 degrees Fahrenheit ("F). Drinking water will be replenished when the quantity of available drinking water drops below 50 percent (%). To accomplish this task, the SSO will provide additional water containers to replace water as needed. When the temperature exceeds 90 'F the SSO will carry ice in a separate container so that when necessary, it will be added to the drinking water to keep it cool. The SSO will check the work site and place the water as close as possible to the workers. Generally, this will be in the site vehicles and no more than 100 feet from the workers, when applicable. lf field terrain prevents the water from being placed as close as possible to the workers, the SSO will bring bottled water or individual containers (in addition to disposable cups and water containers), so that workers can have drinking water readily accessible. The SSO will ensure that the water containers are relocated to follow along as the crew moves, so drinking water will be readily accessible. The SSO will be responsible for ensuring that the water storage containers (if used) are clean and in sanitary condition. All drinking water and drinking supplies will be readily available to all SCI personnel. -21 - SCI Health and Safety Plan Project No. 218102 August 2018 Procedures for Monitoring the Weather At least 24 hours in advance, the SSO or designate will check the extended weather forecast in order to plan in advance the work schedule and know whether a heat wave is expected and if additional schedule modifications will be necessary. The web site to check is: http://www.weather. gov/view/states. php?state=CA&map=on Additional weather information can be obtained from www.nws.noaa.gov, or the Weather Channel TV Network. This type of advance planning should take place all summer long. Weather forecasts can be obtained via telephone from the following: Prior to each workday, the SSO will review the forecasted temperature and humidity for the worksite and compare it against the National Weather Service Heat lndex to evaluate the risk Ievel for heat illness, for instance whether or not workers will be exposed at a temperature and humidity characterized as either "extreme caution" or "extreme danger" for heat illnesses such as heat stroke. lt is important to keep in mind that the temperature at which these warnings occur must be lowered as much as 15 degrees if the workers under consideration are in direct sunlight. Prior to each workday, the SSO or designate will be responsible for monitoring the weather using http.//www.weather.gov/view/states.php?state=CA&map=on or with the aid of a simple thermometer at the worksite. This critical weather information will be taken into consideration, to determine when it will be necessary to make modifications to the work schedule (such as stopping work early, rescheduling the job, working at night or during the cooler hours of the day, increasing the number of water and rest breaks). The SSO will monitor the temperature at the jobsite and periodically check the for sudden increases to ensure that once the temperature exceeds 85 'F, the shade structures are opened and accessible to the workers and to make certain that once the temperature equals or exceeds 95 'F additional preventive measures such as the High Heat Procedures are implemented.

SCI will monitor the weather and in particular be on the lookout for sudden heat wave(s), or increases in temperatures to which employees haven't been exposed to for several weeks or longer. During the hot summer months, and in geographic locations known to have high daytime temperatures the work shift will be rescheduled to start sooner in the day or later in the evening. For new employees, the SSO will try to find ways to lessen the intensity of the employee's work during a two-week break-in period (such as scheduling slower paced, less physically demanding work during the hot parts of the day and the heaviest work activities during the cooler parts of the day (early-morning or evening). Steps taken to lessen the intensity of the workload for new employees will be documented. The SSO will be extra-vigilant with new employees and stay alert to the presence of heat related symptoms. The SSO will assign new employees a "buddy" or experienced coworker to watch each other closely for discomfort or symptoms of heat illness. During a heat wave, the SSO will observe all employees closely (or maintain frequent communication via phone or radio) and be on the lookout for possible symptoms of heat illness. SCI training for employees and supervisors will include the importance of acclimatization, how it is developed and how these company procedures address it. Procedures for Emergency Response prior to assigning a crew to a particular worksite, the SSO will provide workers and the foreman a map along with clear and accurate directions (such as streets or road names, distinguishing features and distances to major roads) of the site, to avoid a delay of emergency medical services. prior to assigning a crew to a particular worksite, the SSO will ensure that a qualified, appropriately trained and equipped person will be available at the site, to render first aid if necessary. prior to the start of the shift, the SSO will determine if a language barrier is present at the site and take steps (such as assigning the responsibility to call emergency medical services to the foreman or an English speaking worker) to ensure that emergency medical services can be immediately called in the event of an emergency.

When a significant change occuts, the protection program shall be reassessed. Reassessntent will involve the Site Supervisor, who will consult with the Project Manager. 2. Soil Management Dur,ilg excavatiop activities, soil l'emoved fi'om the subsurface has the potential to contain hydroJarbon contamination. As stated in Resolution No. 10647 of the proieot "Mitigation N4"ur*'** Section 8, Hazards" (City of San Luis Obispo,2077), "If soil coutamination is exposed dur.ing construction, the San Luis Obispo Fire Departrnent (SLOFD) will be notified and a work plan to chatacterize and possibiy t'elnove contarninated soil will be prepared, submitted aud approved." If contaminated soil is suspected during exoavation, it is recommended that deoSolutions, fnc., be contacted ancl soil be assessed with a flatne ionization detector. Suspect coltaminatecl soil may be stoctcpiled- separately from "clean" soil. Soil disposal alternatives car be discussed with SLOFD. Assessment of encountered contamination can be by a 4O-hour I-Iazwoper trained personnel from GeoSolutions, Inc. 3. GroundwaterManagement During excavation activities and utility installation, groundwater may be encounteled and grounlwater has the potential to contain hydrocarbon contamination. As stated in Resolution No. 10647 of the project "Mitigation Measures Section 8, Hazatds", "If groundwater contamination by potantially hazardous materials is expected to be extracted during dewatering, the SLOFD and Central Coast I{egional Water Quality Control Board (RWQCB) will be notifiecl. A contingency plan to dispose of contaminated groundwater will be developed in agrcement with the SLOFD and Central Coast RV/QCB." Groundwater disposal alternatives can be discussed with RWQCB and SI,OFD. 4. Dust Control Naturally occurring asbestos (NOA) is not suspected at the site. I-Iowever, dust measures during construction ale recommended to be implemented at the site include: a. Construction vehicle speed at the work site must be limited to fifteen (15) miles per hour or less; b. Prior to any ground disturbance, sufficient water tnust be applied to the area^s to be disturbed to prcvent visible emissiotrs fi'om crossing the ploperty line; c. Areas to be gradccl or excavated rnnst be kept aclequately wetted to prevent visible emissions fi'om crossing the propertY line; d. Storage piles nrust be kept adequately wetted, treatcd with a chemical dust suppressant, or covered when material is not being added to or retnoved from the pile; 3 t Materials Managenrerrt Plan - 250 'l'ank Farm Roacl October'26,2011 6.

The drilling/sampling work was conducted on June 28,2OL3 utilizing a direct push GeoProbe drilling rig' 1.0 SCOPE OF INVESTIGATION: UST Area When the UST was removed earlier in the week, it was discovered that the soils immediately below the tank had high levels of hydrocarbons in all three reportable ranges. This layer appeared to only extend approximately 12" below the tank, although samples could only be taken at the far north end of the tank footprint. The tank was found to be located under the southern bay and not the northern bay, so the tank was removed but the existing concrete floor was left in place. This did not allow safe access to obtain samples along the tank footprint and the sides of the excavation. The intent of this drilling work was to confirm that the impacted soils did not extend beyond the building footprint. Samples were analyzed for Total Petroleum Hydrocarbons full range by EPA method 8015 and aromatic volatile compounds by EPA method 8020. .1 BUENARESOURCES Borings were placed on the north end of the tank by hand auger, in the adjacent shed bay, at three locations outside the southern wall of the shed and on the west side of the main building wall adjacent to the tank location. The drilling cuttings were screened for the presence of hydrocarbons in the field by using a Foxbough Organic Vapor Analyzer (OVA). Eastern Leach Field Area Seven borings were placed to a total depth of 8' below ground surface (bgs) along the location of the leach line that was provided by the Farm Bureau. One boring was placed on the far west side of the line near the former septic tank, three at the location of the reported CA hazardous level of nickel and three at the eastern side of the line. These borings were located with the center boring on the estimated location of the leach line and one boring placed on either side of the line at 4'from the line. Samples were taken at2',5'and 8' below ground surface to provide a vertical profile of the impacted zone. These samples were analyzed for TTLC nickel and chromium. 2.0 FIELD BORING & SCREENING: The five (5) Geoprobe borings and one (1) hand boring were placed to varying depths around the former UST location. These borings were intended to confirm that the 12" thick impacted soil zone found below the tank did not extend beyond the building walls. Samples were taken at the depth of the impacted zone, 7.5'bgs, and at the 8.5' bgs depth to confirm that the impacted material is limited vertically. Boring logs have been prepared and are attached to this report showing the soil lithilogy. No visible hydrocarbon contamination or odors were noted during the boring activity. Field OVA results confirmed those observations with no detectable levels noted in any of the drill cuttings' Seven (7) Geoprobe borings were placed along the eastern leach line based on the figures provided by the property owner. Borings were placed on the center of the line and 4' either side of the lineto provide a lateral definition of the impacted soils. Samplesweretaken atthe 2',5' and 8'depths to provide a vertical profile of the impacted soil. Buenaresources A State Certified Small & WBE Business 2 BUENARESOURCES 3.0 SAMPLING AND ANALYTIGAL PLAN: 3.1 Soil SamPlins Plan The UST borings were sampled, as outlined in Section L &2, and analyzed for full range hydrocarbons by EPA method 8015 for gasoline, diesel and motor oil ranges and aromatic organic compounds. The samples taken at the leach field site were analyzed for TTLC nickel and chromium. All drilling was completed with a direct push GeoProbe style drilling rig with all samples taken in acetate sleeves. Soil samples were sealed, labeled, placed in a cooler, chilled to 4" C and shipped to the laboratory by overnight delivery. Analyses were completed according to the various methods specified according to SW-846 guidelines' 3.2 Sampling Maintenance and Securitv Upon collection, the sample containers were labeled in accordance with EPA protocols and chilled pending transportation to Advanced Technology Laboratories, a State certified analytical laboratory located in Signal Hill, California following chain-of-custody procedures' All samples were recorded on Chain-of-Custody forms in ink and transferred to the laboratory according to EpA SW-848 protocol. Any changes or corrections were made by drawing'a line through the error and initialing and dating the correction, then entering the correct information' 4.0 DISCUSSION OF RESULTS: UST Drilline All samples reported levels below established action levels for Total Petroleum Hydrocarbons (TpH) and BTXE with the exception of TK-4-8.5. This sample was taken 3' from the southern wall of the shed which is approximately 9' south of the end of the former UST. This sample reported gasoline at ND but diesel range at 310 mS/kS and motor oil range at 580 mg/kg which exceeds the County action level of 100 mg/kg for all ranges combined. Aromatic organic compound analyses were all below the MDL of 5.0 ug/kg(non-detectable) for all BTXE constituents at all locations sampled. Samples taken farther to the south, west and east of this sample location were all below action level. This would indicate that the soil plume extends a few feet beyond sample point TK-4 to the south but not as far as the other samples taken at TK-5. Buenaresources A State Certified Small & WBE Business 3 BUENARESOURCES Eastern Leach Field TTLC (total metal threshold levels) for chromium and nickel were reported at all locations. We have utilized the WET test results obtained during the earlier sampling on the lOth to make a determination as to which samples would be in the TTLC range that would exceed the STLC thresholds. Sample LF-4-5 reported nickel at 450 me/ke which is higher than the 430 mglkg level at LF-1-5 that previous STLC testing indicated was California hazardous. Sample LF-8-8 also reported TTLC levels of nickel at 760 me/kg and chromium at 800 mg/kg. These levels likely would be hazardous based on the prior STLC results. Additional WET testing was done on this sample to confirm if these levels were California hazardous and TCLP testing was also done to determine if the material was RCRA hazardous for chromium. The WET testing results for LF-8-8 were < 1'0 mg/l for nickel and 12 mg/l for chromium, both of which are below California hazardous levels and considered non hazardous. TCLP results were < 0.05 mg/l which is below the RCRA hazardous thresholds and considered non-hazardous' These results would seem to indicate that the solubility of the nickel is not linear and probably can't be construed from prior work to determine hazardous levels. After reviewing the results for LF-8-8, we will run WET tests on LF-4-5 to determine if the 45O mg/kg level is hazardous requiring removal. 5.0 CONGLUSIONS: The reported results for total petroleum hydrocarbons and aromatic organic compounds were reported at levels below the County action levels with the exception of UST sample TK-4 which did exceed the action level for TPH. This would indicated that the soil plume extends beyond the southern wall more than 3' but less than 13'' Two samples reported levels of nickel that could be considered California hazardous based on the STLC results obtained from the sampling on the 10th. One of those samples reported chromium at 800 mglkg which also required STLC testingto confirm if that level is California hazardous. The results of those WET tests were below California hazardous thresholds with no Buenaresources A State Certified Small & WBE Business 4 BUENARESOURCES further action required. TCLP also confirmed that the higher TTCL levels were not RCRA hazardous material. As noted above, the previous results indicated nickel at 430 mg/kg resulted in a STCL level of 24 mg/l which was CA hazardous material. We initially assumed that the 450 mg/kg reported at LF- 4-5 also would be California hazardous. However, we are having the laboratory run the WET test for nickel at this sample to confirm if the material is hazardous or below the threshold since reviewing the results at the higher sample point at LF-8. This variability in the WET results may be due to the nickel likely compounded with different material which affects its abilityto go into solution. The WET results for LF-4-5 will be available next week which will determine if the leach line and associated soil needs to be removed and disposed.

The District approves the ADMP for the project site. The District understands that the perimeter air monitoring effort will consist of baseline monitoring and monitoring during construction. The samples will consist of one upwind and one downwind sample location and that these locations will be dynamic based upon site specific meteorology throughout the sampling period. Sampling will occur on three (3) days during the start of site grading and when construction activities are being conducted in potential NOA-containing areas. Perimeter sampling may also be required if visible emissions of dust are observed near or crossing the project site boundary. lf the District action level of 0.016 s/cc is exceeded, the District shall be notified immediately. Additional engineering controls may be required (i.e. amended water, etc.) with air monitoring in place to veriff compliance prior to re-starting grading activities. During serpentine disturbance, a misting or fogging pattern is recommended for asbestos fiber control. Please provide all asbestos air monitoring data to the District as soon as it is available. All NOA related data notifications, and general site updates should be sent to the following email: asbestos@slocleanair.org. The ApCD understands that there will be a pre-project meeting with all applicable parties and specifics regarding the plans can be discussed at that time to include the designation of a Certified Asbestos Consultant as the site Asbestos Competent Person. Please notiff the District of the potential date and time of the meeting in order to allow staff the opportunity to attend. It is important to note that the serpentine material from the project site shall not be used as a surfacing material, ground, or abraded. lf hauled off-site, the graded serpentine must be handled as asbestos containing material, unless proven otherwise, using CARB Method 435. r 805.781.5912 I 805.781. 1002 w sloclemainorg 3433 Roberto Court, Sm Luis Obispo, CA 93401 Avila Ranch Developers, lnc.

(Padre) has prepared this Contaminated Materials ManagementPlan (CMMP) at the request of Avila Ranch Developers, lnc. (Avila Ranch) for the planned construction activities associated with the Avila Ranch Development Project in San Luis Obispo, San Luis Obispo County, California (Project Site). The location of the Project Site is presented on Plate 1 - Site Location Map. Padre understands that Specialty Construction, lnc. (SCl), theoff-site utility contractor for Avila Ranch, will be constructing a sanitary sewer pipeline from the Project Site to the Tank Farm Sewer Lift Station located on Tank Farm Road. Areas along TankFarm Road have previously been documented to contain total petroleum hydrocarbon (TPH)- containing soil and groundwater associated with historical releases from the former Unocal TankFarm Road pipelines, which have since been permanently decommissioned. This CMMPprovides information pertaining to the previous site assessment activities completed along TankFarm Road and outlines the recommended process for managing TPH-containing soil andgroundwater during the course of the planned construction of the sewer line. 1.1 OVERVIEW The Tank Farm Road area has been documented with TPH-containing soil andgroundwater associated with historical petroleum pipeline operations (refer to Plate 2). The lead regulatory agency for the identified TPH-containing soil documented in the area of the ProjectSite is the City of San Luis Obispo Fire Department (SLOFD), acting as the Certified Unified Program Agency (CUPA). Groundwater quality in the vicinity of the Project Site is regulated by the Central Coast Regional Water Quality Control Board (RWOCB). The purpose of this CMMPis to present an overview of the procedures and protocols that should be utilized during theProject to safely and appropriately recover, handle, characterize, store, transport, and dispose of any contaminated materials generated during the Project. The information, content, and guidance presented in this CMMP have been prepared toaddress local, state, and federal statutes and regulations as well as project speciflc permits,plans, and requirements. Using guidance provided in this CMMP will allow Project fieldpersonnel to effectively manage contaminated materials waste generated during the proposed sanitary sewer line tie-in construction activities within Tank Farm Road. This CMMP can be amended in the field, as necessary. All revisions and amendments must be documented and approved by SLOFD and RWQCB, as appropriate. 1.2 CMMP ORGANIZATION This CMMP is organized into the following sections: Section 2.0 presents backgroundinformation for the Project Site, including a discussion of location, topography, geology, hydrogeology, and a description of historical assessment activities performed at the Project Site, including a discussion of the nature and extent of impacts to soil and groundwater; Section 3.0provides the methodology for management of contaminated materials at the Project Site;Section 4.0 presents reporting requirements; and Section 5.0 provides the documents referenced within this CMMP. This CMMP includes three appendices: Appendix A provides 1 June 2020 Project No. 1901-0154 l'adrel.rloclate3. lnc.! exorreens, c:oroorsrs eH FNvr.dNuFEAL scrEf,ffis historical analytical data summary tables; Appendix B includes selected geologic cross-sections of the Tank Farm Road Pipeline Site; and Appendix C contains a project contact list. 2.0 BACKGROUND 2.1 PROJECT SITE DESCRIPTION Avila Ranch Development is located within San Luis Obispo city limits, northeast of the intersection of Buckley Road and Vachell Lane, and extends for approximately 0.75 miles along Buckley Road east of this intersection. The Project Site consists of three parcels totaling'150 acres within Assessol's Parcel Numbers (APNs) 053-259-004, 053-259-005, and 053-259-006. The Project Site is surrounded by industrial and commercial development to the north and west, and by agricultural lands located within the unincorporated areas of the County of San Luis Obispo to the south and east; and the San Luis Obispo County Regional Airport lies 0.6 mile east of the Project Site. Land use in the Project vicinity is characterized by a mixture of undeveloped open areas, agriculture, and urban industrial development. Existing nearby development consists primarily of light industrial and commercial uses to the west and north of the Project Site along South Higuera Street, Vachell Lane, Suburban Road, and Tank Farm Road. Development along these roads includes large light manufacturing facilities, older structures with a mixture of storage yards, and multi-tenant commercial complexes. The following sections provide an overview of the site history, geologic and hydrogeologic setting, and the extent of impact by crude oil released from the Unocal Tank Farm Road pipelines. Historical groundwater analytical data collected from 1988 through 2006 are tabulated and depicted graphically in Appendix A. 2.2 PIPELINE HISTORY Unocal's Tank Farm Road pipelines extend parallel to and beneath Tank Farm Road, west of the former Unocal San Luis Obispo Tank Farm property. The area of previous soil assessment activities extends west from the former Tank Farm property westerly to South Higuera Street and includes up to 15 parcels of property adjoining either side of Tank Farm Road. A linear area along each side (<150 feet wide) of Tank Farm Road has been documented to be affected by the crude oil release. The study area is depicted on Plate 2 - Assessment Locations. The former petroleum pipelines were a component of a pipeline system constructed around 1906, with line renewal projects in 1930 and 1952. The most recent pipeline configuration included two, 8-inch-diameter steel pipes that were installed in 1952. Beginning in the 1980s, the operational need for the Tank Farm diminished and the Tank Farm and pipelines were used only during severe cold weather as an oil heating station on the pipeline from Santa Margarita to Avila Beach. The last time the facility was used to heat crude oil was in 1986. The pipelines were formally decommissioned (cleaned and sealed) in 2001 (Avocet Environmental, 2007). -2- June 2020 Prolect No. 1901-0154 padreI a3tociato3. lnc.I erorr:ens,orordotsrs eE ENVIRONBEEALSCEffi! 2.3 ASSESSMENT HISTORY ln April 1988, local landowners notified Unocal that crude oil had been detected in thesoil beneath their properties during a real estate pre-purchase soils investigation (pacific Geoscience, lnc., 1988). Following this discovery, Unocal retained Brown & Caldwell to initiatean investigation to define the limits of the crude oil-containing soil (Brown & Caldwell, 1988 and1989). Dames & Moore was later retained to further delineate the limits of TPH soil andgroundwater contamination (Dames & Moore, 1990). From 1991 to 2005, multiple phases ofsite assessment activities were performed along the Tank Farm Road area by Unocal'sconsultants, specifically England Geosystem (2001); Earth Systems Pacific (2003); and AvocetEnvironmental (2007), to more accurately define the extent of petroleum contamination. The RWQCB is the lead regulatory agency that has directed assessment activities at theTank Farm Road Pipeline site (Case #5L203031242). On September 22,2014, the RWQCBissued a Public Notice that provided a rationale for granting closure of the case, citing thefollowing points: 1. The extent of pollutants in soil and groundwater has been adequately characterized 2. Remedial options to actively remove remaining pollution are limited due to thepredominance of fine-grained soils beneath the site, the highly viscous character ofthe crude oil, which adsorbs to soil and soil pores, and development along TankFarm Road, which makes excavation and disposal of impacted soil extremelyexpensive and would create a significant public disturbance. 3. Remaining petroleum hydrocarbons in groundwater are confined to shallowgroundwater and are not migrating; and groundwater monitoring wells locatedhydrogeologically downgradient of the plume did not have detectable concentrations of TPH when last sampled in 2006. 4. Remaining petroleum hydrocarbons in soils and groundwater are in a stable plume that is undergoing natural biodegradation. 5. The depth of petroleum hydrocarbon-impacted soil and groundwater (10 to 30 feet below ground surface) makes physical contact with pollutants unlikely. 6. Aquifer tests have shown that groundwater from the shallow zone does not migrate to deeper wells. 7. The County of San Luis Obispo requires S0-foot seals on all water supply wells toprevent cross-contamination of aquifers; any groundwater wells installed in theplume area would be sealed throughout the impacted area, which extends toapproximately 30 feet. 8. The City of San Luis Obispo now supplies water to developed properties along Tank Farm Road, reducing the need for groundwater supply wells. -3- June 2020 Project No. 1901-0154 ]'adrel.iioclatos, lnc.I rrorr:ens, o:ordotsrs a The RWQCB concluded that there is no significant threat to human health or the environment from the remaining TPH Affected Soil and Groundwater located at the Tank Farm Road Pipeline site (RWQCB,2014). 2.4 GEOLOGY AND HYDROGEOLOGY The Project Site is located in the San Luis Valley, a relatively level, narrow, alluvium- filled basin in the Coast Ranges Geomorphic Province. Numerous exploratory drill holes and water well drilled in the site vicinity indicate that this alluvium consists of approximately 160 feet of laterally discontinuous interbeds of gravel, sand, silt, and clay. The lithologic logs indicate that fine-grained lithologies (silt and clay) predominate in the upper 100 feet, whereas coarse lithologies (sand and gravel) predominate at depth. The alluvium rests unconformably upon bedrock of the Franciscan Formation. Refer to Cross Sections A-A' and B-B' in Appendix B for a cross-section at the Project Site. The alluvium comprises the major groundwater aquifer in the San Luis Obispo groundwater basin. ln the site area, groundwater has been measured at depths ranging from 7 to more than 30 feet below ground surface. Both long-term and seasonal fluctuations in groundwater levels have been recorded. Observations of rising water levels in exploratory borings indicate that the shallow groundwater is largely semiconfined with local confined and unconfined zones. The potentiometric surface slopes to the southwest (mean flow direction =S65"W with a gradient ranging from approximately 0.002 to 0.008 fooVfoot. Recharge apparently occurs over the entire aquifer mainly through precipitation events. Analytical test results of groundwater from the deeper zone (greater than 50 feet bgs) showed that contaminants associated with the overlying crude oil were not drawn down into wells completed in the lower saturated zone. lt was concluded that domestic groundwater wells constructed in accordance with County of San Luis Obispo well construction standards can be safely installed within the contaminated area without the risk of bioreceptor exposure to crude oil constituents in water (Avocet Environmental, 2007). 2.5 IDENTIFICATION OF AFFECTED SOIL AND GROUNDWATER SCI completed two test excavations along the north side of Tank Farm Road, on either side of the existing driveway at250 Tank Farm Road, on February 14,2017. Mr. EricSnelling of Padre was on-site during the course of the test excavation activities and observed that TPH- containing soil and groundwater were encountered at each location. According to SCl, soil impacts were indicated at elevations of 112 to 1 13 feet above mean sea level, approximately 1 1 to 12 feet below ground surface. 4 June 2020 Proiect No. 1901-0154 padre l arloclatg8. lno.I enotrreng, oeoro'crers eH FtrvrrdNsffiAr ..FNmrc 3.0 METHODOLOGY This section outlines the roles and responsibilities for identifying and managing contaminated materials during sewer pipeline construction activities along Tank Farm Road. Padre understands that Avila Ranch plans to have a representative at the Project Site duringthe course of any construction activities that will potentially encounter TPH-containing soil andgroundwater. 3.1 NOTIFICATION Padre, on behalf of Avila Ranch, will notify the RWQCB and SLOFD, as well as ChevronEnvironmental Management Company, of the upcoming construction activities that may encounter contaminated materials. 3.2 HEALTH AND SAFETY PLAN Padre has prepared a Health and Safety Plan (HASP) that will cover Padre and SCIpersonnel during the course of the pipeline construction activities. The HASP meets the requirements set by state and federal Occupational Health and Safety Standards per Title 29,Code of Federal Regulations (CFR), subpart 1910.120(bX4). The HASP includes theprocedures, equipment, and materials/supplies to be utilized at the Project Site to protect worker and community health and safety during the course of the pipeline construction activities. 3.3 FIELD PROCEDURES AND PROTOCOLS A trained and experienced Padre field monitor, under the direction of a Padre State ofCalifornia Professional Geologist or Engineer, will conduct on-site monitoring and waste management activities during the course of the Project construction activities within areas of TPH-containing soil and groundwater. Padre will advise Avila Ranch, who in turn will direct SCI to segregate contaminated soils from clean soils. The field monitor will conduct field screening of suspect soils to identify and segregate the TPH-containing materials. The soil will be screened visually and through the use of a fieldportable photoionization detector (PlD). Soil samples will be collected from stockpiled soils todetermine whether the soil is potentially acceptable for re-use or will require disposal as regulated waste at a licensed disposal facility. Padre will also assist with waste characterization and disposal facility waste acceptance. Excavations within TPH-affected areas will be backfilled in the same day in a mannerthat minimizes groundwater intrusion. ln the event that TPH-containing groundwater isencountered during excavation activities, Padre will collect groundwater samples for characterization purposes. Groundwater will be pumped from the excavation into a portable storage tank stored within the work area. t June 2020 Project No. 1901-0154 t'adrel aa!oclatg!. lnc.! :rorrreas, orordcrers aE ENVIBOilfflTAISCETffiB 3.3.1 Sample Collection Program ln the event that soil excavation activities encounter TPH-containing soil, confirmation soil samples will be collected directly from the excavations and/or stockpiled materials for chemical analyses using laboratory-provided sampling supplies. Soil samples will be collected utilizing four-ounce glass jars with Teflon-lined lids, and will be sealed, labeled, and placed in a properly pre-cooled ice chest immediately following collection. Sample collection will be documented in the field monitor's log and on a site map. The samples will be delivered to an independent, state-certified analytical laboratory certified by the State of California Public Health Department, and chain-of-custody (COC) forms will be used to document sample management. The samples will be chemically analyzed for the following analytes to allow for possible disposal at Cold Canyon Landfill in San Luis Obispo, California. Groundwater samples will also be collected from the excavations utilizing glass containers with Teflon lined septa if potentially contaminated groundwater is encountered during excavation activities. 3.3.2 Laboratory Analytical Program Suspected contaminated materials samples collected during the course of the Project will be submitted to Oilfield Environmental and Compliance, lnc. (OEC) of Santa Maria, California, on a 24-hour rush turn-around for the following chemical analyses. OEC is certified by the State of California to perform the required analyses: TPH as diesel fuel and motor oil by U.S. Environmental Protection Agency (EPA) method 8015 modified; and a . TPH as gasoline and volatile organic compounds (VOCs) by U.S. EPA method 8260. One waste characterization soil sample will be chemically analyzed for the following constituents to gain pre-acceptance at the designated landfill facility: . TPH and TPH-DI WET (waste extraction test) by U.S. EPA method 8015M; . Organo-chlorine pesticides by U.S. EPA method 8081; . Polychlorinated biphenyls (PCBs) by U.S. EPA method 8082; .

Handling and Stockpiling of Contaminated Materials During excavation activities, uncontaminated materials will be stockpiled adjacent to the excavation for reuse as fill material during the backfill and compaction process. ln the event that TPH-containing soil is encountered during excavation activities, the contaminated soil willbe excavated to the extent necessary to safely execute Project construction activities. Soils indicated with TPH concentrations in excess of 100 milligram per kilogram (mg/kg), based on chemical analyses, will not be used for backfill material at the Project site. Designated contaminated stockpile areas will be identified at the work area prior to the initiation of construction activities and employ the following best management practices: o SCI will segregate and stockpile TPH-containing soil on plastic sheeting and covered with either plastic sheeting or an APCD-approved soil tackifier; . Covers on stockpiled materials will be maintained in place at all times when not actively involved in soil addition or removal; . No headspace shall be allowed by the covering where vapors could accumulate;. Covered piles will be designed in such a way to eliminate erosion due to water orpublic nuisance; and . Clean soils will be segregated from contaminated soils. 3.3.4 Management of Materials TPH-containing soil will be transported and disposed of off-site at Cold Canyon Landfillin San Luis Obispo, California or other appropriately permitted landfill facility. TPH-containinggroundwater will be temporarily stored on-site in portable storage tanks equipped with vapor- phase granular activated carbon (GAC) drums to controlfugitive emissions. 3.4 EQUIPMENT DECONTAMINATION All equipment that comes in contact with TPH-containing soil and groundwater will be appropriately decontaminated by SCI prior to leaving the work area. -7 - June 2020 Proiect No. 1901-0154 padreI i.rocIaler. lno.I erorrr:ns. o:ordotgrs aH E!v,.^!uGwrr a.Erffi 4.0 REPORTING Following completion of the project construction activities, Padre will prepare a completion report, which will include the volume of contaminated soils and/or groundwater removed, results of sampling and laboratory analyses, and the disposition of contaminated materials. Copies of all laboratory analytical reports and waste manifests will be included with the report. The report will be submitted in draft form to Avila Ranch for review and comment. Following the receipt of comments from Avila Ranch, Padre will revise the report for submittal to SLOFD and RWQCB. The report will be signed and certified by a Professional Geologist or Professional Engineer registered in the State of California. -8- June 2020 Project No. 1901-0154 padrel artoclato8.

Based on a determination by the Regional Water Quality Control Board and a Health Risk Assessment (FnA) prepared by England and Associates referred to in Spencer's memo, no soil remediation is required at thistime. If contamination is encountered in the course of installing utilities and right-of-way improvements, the recommendations in the HRA must be followed. Spencer notes that a separate Health Risk Assessment will be required to specifically address any future development on lots with known soil contamination. Requirements for notification are also outlined in the attached memo. Council action on the tentative map is final and compliance with conditions I and 2 is overseen by the Fire Department.

As we discussed on Septemier 26, 1996, Unocal requests a similar letter for the Strasbaugh property so that development can proceed on that site' The July 12, 1996 Earth systems consultants site assessment delineated the soil contamination to the 100 ppm total petroleum hydrocarbon contour. Shallowest depth to contamination is 16 feet, well below any potential excavation for utility construction on the Strasbaugh proPertY. The England & Associates' pump test results indicate that a negligible degree of hydraulic communication exists between the shallow ground water at the site and ground water occurring at depths in excess of 50 feet. Thus ihe county minimum requirement of 50 feet of sanitaryleal is sufficient to protect potential drinking water wells in the area. We have received the September 26,1996 letter from the Fire Department stating that the Fire Department takes no exception to the conclusion in Health Risk Assessment prepared by England and Associates. The Fire Department has requested a site safety plan. It is my understanding from our September 26 telephone conversation that you will consider issuing a letter to Un'ocal indicating that groundwater issues will not effect the development plans for the Stasbaugh ProPertY' lf you have any questions, please call me at (805) 348-3126. 4 4., cc: Sincerely,Z John R.

Tangeman Sinsheimer, Schiebelhut & Baggett 1010 Peach St. P.O. Box 31 San Luis Obispo, CA 93406 Re: Minor Subdivision SLO 96-057 (Strasbaugh) Dear Marty: This letter is to follow-up on our meeting of April 28, 1998, and your subsequent letter of April 30, 1998 concerning the conditions of approval for Minor Subdivision SLO 96-057. After further d.iscussions with staff, it is our conclusion that the February 10, 19gT letter from the Central Coast Regional Water Quality Control Board to John Ljung of Unocal Corporation (copy attached) will be sufficient to satisfu Condition 1 of Mitto" Subdivision SLO gG-057, and that your client may proceed to final map approval providing all other cond.itions and requirements are met. In this regard, it is my undlrstandilng that the final map has not yet,been submitted by Central Coast Errgirreuring, and therefore has not been reviewed' for compliance by the City' I would also note that at our April 28, 1998 meeting certain assertions were made by Unocal representatives that the Regional Water Quality Control Board was not concerned about lJnocal's petroleum hydrocarbon releases beneath the Strasbaugh property, and. that the February 10, 1998 letter from the Board was essentially a icleun bill of health" for purposes of development. In fact ,the Board has shown continued interest and concern over this issue, and has recently ordered additional information and monitoring. (Please see the attached April 29,1998letter from RWqCB to Unocal.) In short, the issue of site contamination and how to address it has not been fullY resolved. While we have concluded that the map may be finaled on the strength of the February 10, 1gg8 RWQCB letter, the issue of actual development of the newly created parcels is a separate matter which will need to be addressed at the time of specifi,c development apptications. As you know, Condition 2 of SLO 96-057 provides [rE-l ,n" City ol San Luis Obispo is committed to include the disabled in all of its services, programs and activities't\-rLl feleconimunications Deviie for the Deaf (805) 781-7410. Martin A. Tangeman May t2,1998 Page Two that "... no buildings, septic systems, roads, utilities, or other structures shall be constructed above itt" upp"oximate area of contamination." Based on this condition and the unresolved issues of site contamination, the City will require a site specific Health Risk Assessment acceptable to the City and the RWQCB prior to development on any of the affected Parcels. As we have previously discussed, a final concern is to make sure that any prospective purchasers of the affected lots have adequate notice of the contamination irr.r"., and ihe potential restrictions on development. To that end, the City will require such a recorded notice prior to acceptance of the frnal map for SLO 96-057' I ani currently drafting a form of notice and will provide it to you shortly.

Howard Strasbaugh, Inc. at the corner of Tank Farm Road and South Higuera in San Luis Obispo. That property is the subject of subdivision map approval for a division of a single parcel of approximat ely 13.73 acres into five parcels. A condition to final map approval for this project is the following: "Under direction of the Fire Department, soil contamination must be removed prior to development of the affected lots and in no case later than the initial expiration of the tentative map for the subdivision. The clean up level shall be 100 ppm (parts per million) unless otherwise specified by the Regional Water Quality Control Board." A copy of this condition for project ER74-96,located at3897 South Higuera Street, is enclosed. We are awale of simiiar problems in conneciion with the TK developmerrt project across the street. Enclosed is a copy of a letter dated August 30, 1996, from the California Regional Water Quality Control Board, noting that the Board would not require Unocal to remove any soil from that location. In addition, our client received a copy of a letter from the City of San Luis Obispo Fire Department, dated September 26,1996, which acknowledges receipt of, and takes no exception to, an England & Associates Health Risk Assessment for the Tank Farm Road Pipeline, which is also enclosed. That letter required Unocal to prepare a "Comprehensive Area Health and Safety Plan". Another letter dated March 5,1997 from the City of San Luis Obispo Fire Department acknowledged receipt of the Safety Plan. I enclose copies of these letters. Jeff Jorgensen April21, 1998 Page2 We would appreciate knowing what more, if anything, needs to be done to obtain final map approval for the subject property. Strasbaugh LLC has nearly finished all other conditions for map approval, and would like to proceed to final map approval as soon as possible. I look forward to meeting with you on April 28,1998, at 3:00 p.m. in your office, along with Unocal representatives, to resolve this matter Very truly yours, SIN & BAGGETT GEMAN MJT:tlg G:\GENERALTITR\STRASBAL\z4JORGEN.420 Enclosures Michael Morris Lany Strasbaugh S cc G sloel -152).

Box 31 San Luis Obispo, CA 93406 Re: Minor Subdivision SLO 96-05? (Strasbaugh) Dear Marty: This letter is to followlup oll our meeting ofApril 28, 1998, and your subsequent letter of April 30, 1998 concerning the conditions of approval for Minor Subdivision SLO 96-057. After further diecussiong with staff, it is our conclusion that the February 10, 199? letter from the Central Coast Regional Water Quality Control Board to John Ljung of Unocal Corporation (copy attached) will be sufficient to satisfu Condition I of Minor Subdivision SLO 96.05?, and that your client may proceed to linal map approval providing all other cpnditione and requirements are met. In this regard, it is my understanding that the final map has not yet been submitted by Central Coaet Engineering, and therefore has not been reviewed for compliance by the City. I would also note that at our April 28, 1998 meeting certain assertions were gade by Unocal representatives that the Regional Water Quality Control Board wae not conccrned about Unocal's petroleum hydrocarbon releases beneath the Strasbaugh property, and that the February 1.0, 1998letter from the Boardwas essentially a "clean bill of health" for pu{poses of development. In fact,the Board has shown continued interest and concern over this issue, and has recently ordered additional information and monitoring. (Please see the attached April 29, 1998 letter from RWQCB to Unocal.) In short, the issue of site contamination and hovr to address it has not been fully resolved. While we have concluded that the map may be finaled on the strength of the Fehruary 10, 1998 RWQCB letter, the issue of actual development of the newly created parcels is a separate matter which will need to be addressed at the time of specific development applications. As you know, Condition I of SLO 96-057 providesIt\ coA. z oC "'" P.2 5-1 1-1994 2 'A?PM FROM ATTORNEY' SLO A@57A174P9 that "... no buildings, septic systems, roads, utilities, or othel structures shall be con$tructed above ihe appraximate area of contamination." Based on this condition ur,a tn" unresolved issues of site contamination, the CiE will require a site Fpecifrc Health Risk Asgessment acceptable to the City and the RWQCB prior to development on any ofthe affected Parcels. As we have previously discussed, a final concetn is to make sure that any p"o*p""titre purchasers of the affected lots have adequate notice of the contamination ir"*"r, and ihe potential restrictions on development. To that end, the City will require " r""o"d"d notice in a form substantially similar to Attachment 3, prior to acceptance of the final map for SLO 96'057' If you have further questions or comments, please feel free to contaqt me at your convenience.

Despite our objections that these conditions should not be enforced against the property owner, but instead the source of the contamination, Unocal, Mr. Larry Strasbaugh, on behalf of Strasbaugh lnc,. agreed to these mitigation measures to enable the project applications to proceed. His legal advisors are" however, concemed that this obligation is rnisplaced. The Higuera Commerce Park Specific Plan amendments regarding serv'ice comrnercial land uses and reduclion of minimum lot size were approved by the City in August and September, 1996, enablingthe processing of MS 74-96 (SLO) 96-057. The approval of the vesting tentative map for SLO 96-057 occurred on January l7,1997 as indicated in the attached Director's Action No. 9?-01. Please note thal the prior mitigation measuresI and2 were convertsd to conditions of vesting tentative map approval. Technical studies conducted for Unocal have treen subrnitted to the City and WQCB for review during the last year, including a site assessmenl report prepared by Earth Systems Consultants, a Report of Hydrogeologic Evaluation, Straslraugh Property, a Supplemental Health Risk Assessment, and a Health and Safety Plan, prepared by lingland and Associates. The response received, based on the information submitted by Unocal, is reflected in the altached letter from CaliEPA, the Central Coast Regional Water Quality Clontrol Board, dated February 10, 1997, The letter concludes:"At this time this Board willnot require Unocal to remediate its petroleum lrydrurorLurrs irr suils luuatsd bsrrvatlr tlrc Strasbaugh lrruptrray arltl Tallk Farrrl Rtrad," attd 73149 BEL AtR ROAO, PnUl DeSrar, CALTFORNTA 92260 PHONE/FAX (619) 341-2798 ffi 4il( SrnoNG PMruNING STRVICES Roe Srnoruc, A.l.C.P November 8, 1996 Mr. Rick Siske I.INOCAL CORPORATION Environmental Remediation Services 276Tat*Farm Road San Luis Obispo, CA93406 Subject: Higuera Commerce.Park , Northeast Corner of Higuera Street and Tank Farm Road, San Luis Obis2o, CA: Re Underground Contamination Remediation. Dear Mr. Siske: Although we have initiated m?ny telephone calls and received several technical reports regarding the underground contamination caused by a Unocal pipeline leak along the Tank Farm Road right of way in San Luis Obispo, we have not received a specific response to my letter to you dated September 13,1996. As I previously explained, I represent Strasbaugh, owners of the property on the north side of Tank Farm Road east of Higuera Street, currently pursuing parcel map SLO 96- 057, which requires mitigation to satisfr both Water Quality Control Board and the City of San Luis Obispo. I have had numerous conversations with Mr. Spencer Meyer of the San Luis Obispo Fire Departm.ent and with Frank DeMarco of the State Regional Water Qualrty Control Board, indicittv,g that the most recent determination (August 30, 1996) regarding the T.K, Development Project is that WQCB "will not require Unocal to remorre any soil from this loc4tion at this time," and that WQCB "feel that development of Tract # 2202 may proceed." Strasbaugh is, of course expecting at least a similar letter from WQCB regarding the north side of Tank Farm Road and parcel maps SLO 9l- 152 and96-057. By copy ofthis letter to Frank DeMarco and Bob Baldridge of WQCB, we are asking for a similar letter tr us with a copy to the City concerning our property. I am also requesting Spencer Nfeyer of the City Fire Department and Arnoid Jonas, Director of Community Development, to verify that this finding will suffice regarding ER74-96, condition # 1 and related; percel map conditions of approval requiring cleanup as specified by the Regional Water Quality Control Board. According to Spencer Meyer, hbwever, the City is still waiting to receive a Health and Safety Plan from Unocal, before construction of street and utility improvements could begin by either T.K, or Strasbaugh. Strasbaugh has already suffered delay and damages due to this contamination problem, including the extra costs of mv services, inability to complete the street and utility improvements along Tank Fa"ln Road and delay in development and reduced valge when marketing the eight acres alonl; the north side of Tank Farm Road. 73149 BEL AtR R9AD, PRlrra DesenT, CALIFoRNtn 92260 PHoNE/FAX (619) 341-2798 filf tilPY , Page2 At this time, we are prepared to file the final map of SLO 9l-152, and intend to bond for these remaining improvements, until the City or T.I( are ready to install, without fear of future removal due to the contamination, We believe that the bids for construction will be higher than if the contamination were not a construction concern, and need your written response as to how Unocal will compensate Strasbaugh for these damages and expenses. We are prepared to hire appraisers or other real estate professionals to document the reduced value that this contann^r'tntion causes for future use and development of the vacant eight acres, including difficulty in financing buildings and improvements, selling or leasing, and possible disruption to buqiness if the City or WQCB ever decide to require clean up. It is our understanding that Unocal indemnification agreement dated May 6, 1996, provides for Unocal to be responsible for these and other costs, but we request your immediate response to clariS how we should obtain payment or reimbursement without litigation. If we have not received the necessary WQCB, City and your response by December l, 1996, we will incur additional expense and employ an attorney to pursue our interests.

We have received Risk Assessments for the TK and Strasbaugh properties, although not specifically for the public right-of-ways (around the properties that are contaminated, i. e.

The assessment was conducted to evaluate the levels of petroleum hydrocarbons in soils along the proposed alignment of a city sewer line. The assessment consisted of drilling l3 soil bor-ings, ar"rd laboratory analysis of 33 soit samples for total extractable petroleum hydrocarbons. Total extractable petroleum hydrocarbons (TEPH) were detected in 8 of the 13 borings drilled on the site. TEPH concentrations ranged from 260 to 9,000 milligrams per kilogram. The carbon chain length for the hydrocarbons detected was from C1g to C36, which is within the range typical of crude oil. With the exception of boring GPT-5, TEPH was not detected in borings west of Long Street. The highest concentrations of TEPH were found in the vicinity of borings GPT-11' GPT-12 and GPT-13, which are in the easternmost part of the study area. TEPH was not found by laboratory analysis in soils shallower than 8 feet below ground surface, with the highest concentratiols found at depths between 16 and 20 feet below grade. Field evidence of hydrocarbons was not otrserved at depths shallower than 10 feet below ground surface. Groundwater was encountered in eight of the thirteen borings, at depths ranging fi'om 13 to 18.5 feet below gr.ound surface. The static water level in well SLOW-4, near the central part of the study afea, was measured at 14-59 f'eet below ground surface in June 1996- 1j 111 Tank Farm Road Sewer Line September 11, 1996 1.0 INTRODUCTION This repolt presents the results of a subsurface site assessment conducted in the alignment of a proposed sewer line along the south side of Tank Farm Road in San Luis Obispo, California. The assessment was performed with the intent to evaluate the distribution and extent of petroleum hydrocarbons adjacent to a Unocal pipeline easement which parallels the north side of the alignmenl Work performed in this assessment has consisted of: Drilling 13 exploratory borings to a maximum depth of 20 feet below grade Collection of soil samples from various depths in the borings Laboratory analysis of 33 soil samples for total extractable petroleum hydrocarbons (TEPH) Data analysis and preparation of this rcpoft 2.0 BACKGROUND The study arca is situated on the south side of Tank Farm Road, east of Higuera Street, in San Luis Obispo, California (see Figure 1). The site consists of the southern edge of the Tank Farm Road right-of-way. The area to the south of Tank Farm Road is presently occupied by fallow agricultural land. The study site is situated in an area of commerciaUindustrial and agricultural uses. The Tank Farm Road right-of-way also contains an easement for two Unocal petroleum pipelines, which are located approximately 35 feet north of the proposed sewer line. It is our understanding that a 3O-foot wide strip along the south side of Tank Farm Road has been offered to the City of San Luis Obispo for a planned widening of the existing right-of-way. Assessments of soil and groundwater conditions in the Tank Farm Road area between Higuera Street and the Unocal Tank Farm have been conducted by various consultants between 1988 and 1996. DuLing these assessments, petroleum hydrocarbons wele found in soils in a boring in the northeast corner of the subject property (Brown & Caldwell, 1988, 1989; Dames & Moote, 1990). A monitoring well (SLOW-4) was installed just south of the center portion of the study area in 1988; this well has lreen monitoted on a quarterly basis since 1990. a a a _l NGL10173-0r 9609-106.RPT Tank Farm Road Sewer Line September ll, 1996 The City of San Luis Obispo is planning to install a sewer line along the south side of Tank Farm Road in conjunction with annexation of the Airport Area. In light of the findings of earlier site assessments, this study was undertaken to evaluate the extent of hydrocarbons along the proposed sewer line alignment The emphasis in this study has been to identify the vertical extent of hydrocarbons, and determine what impact, if any, their presence would have on sewer construction. 3.0 REGIONAL GEOLOGY AND HYDROGEOLOGY The subject site is situated at the eastern end of the Los Osos Valley, a northwest-trending valley which extends from the San Luis Obispo Airport area to Mono Bay. The valley is underlain by Recent alluvium deposited by San Luis Obispo and Prefumo Creeks, consisting of mostly fine grained deposits of silt and clay, with interbedded sand and gravel. The alluvium is underlain by metamorphic rocks of the Franciscan formation and sedimentary rocks of the Monterey formation (Hall and Prior, 1975). The primary structuml feature in the area is the Los Osos fault, which is situated approximately 1 mile south of the site. Gtoundwater in the area of the site is produced primarily from Recent alluvium, although some deepel wells produce water from fractured rocks of the Franciscan and Monterey formations (CDWR, I970). County well construction standards requirc a minimum 50-foot deep sanitary seal for supply wells in this area. Depth to first groundwater vades widely in the vicinity of the site, and appears to depend mostly on infiltration from precipitation. The degree of communication between the upper perched aquifer and the under{ying supply aquifer is negligible, based on results of pumping tests conducted on properties immediately adjacent to the study area (England-Shahin, 1992; England,1996). Based on data collected from quarterly groundwater monitoring conducted between 1990 and 1996, depth to groundwater in the perched aquifer beneath the site has varied seasonally from 2.8 to 22 feet below grcund surface (hgs). The regional groundwater gradient direction in the perched aquit'er is to the west-southwest. 2NGLl0l73-01 9609-106.RPT Tank Fann Road Sewer Line September II,1996 4.0 FIELD INVESTIGATION Drilling and Soil Sampling On May 15 and 16, 1996, a total of 13 soil borings were advanced at the locations shown on Figure 2. Prior to drilling, Underground Service Alert (USA) was notified to mark utilities in the alea to avoid damage by subsurface exploration. The bortngs were advanced using a Geoprobe G5400 direct push sampling rig, using 1.5-inch diameter core. Samples were collected from the borings at approximately 4-foot interuals A California Registered Geologist was ptesent to log fte borings, collect soil samples and monitor soils for field evidence of hydrocarbons. Hydrocarbon vapors were monitored with a photoionization detector (PID), calibrated to isobutylene. Drilling and sampling tools were cleaned between borings to reduce the potential for cross-contamination. After sampling, the borings were backfilled with bentonite chips and hydrated. Boring logs for the Geoprobe borings arc attached as Appendix A. Laboratory Analysis of Soil Samples Laboratory analysis was performed at ZymaxEnvirotechnology in San Luis Obispo. A totat of 33 soil samples were submitted for analysis. The samples were analyzed for total extractable petroleum hydlocarbons (TEPH) by gas chromatography/mass spectroscopy (GC/MS, equivalent to EPA Test Method8270). 5.0 FINDINGS OF FIELD INVESTIGATION Soil Conditions Earth materials beneath the site consist of several feet of dark brown sandy clay topsoil, underlain by sandy clay and gravelly clay, with interbedded gravelly sand, clayey sand and silty clay layers. Soils in the western part of the site are predominantly fine-grained, consisting of sandy and silty clays, and clayey silts. The eastern portion of the site, east of Long Street, contains predominantly coarser soils, consisting of clayey sand, clayey gravel, silty sand and gravelly sand. Boring locations are shown on Figure 2. JNGLl0173-01 9609-106.RPT Tank Farm Road Sewer Line September 11, 1996 In all of the Geoprobe borings in which hydrocarbons were detected by laboratory analysis, field indications of hydrocarhons (odor, staining) were not observed at depths shallower than 8 feet below ground surface. In most of these borings, field indications of hydrocarbons were not observed at depths shallower than 12 feet below grade. PID readings were non-detectable in borings GPT-1, GPT-2, GPT-3, GPT-4, GPT-6. PID readings ranged from 6 to 26A parts per million by volume (ppmv), in borings GPT-S, GPT-7, GPT-8, GPT-p, GPT-10, GPT-11, GPT-12 and GPT-13. The highest readings were obtained from samples collected between 16 and 20 feetbgs. PID readings are recorded on the boring logs. Groundwater Conditions Groundwater was encountered in 8 of the 13 borings, at depths ranging from 13 to 18.5 feet below ground surface. Groundwatef was not encountered in borings GPT-5, GPT-6, GPT-7, GPT-8 and GPT-10, which were drilled to depths of 20 feet bgs. On June 10, 1996, groundwater was measured at a depth of 14.58 feet below top of casing in well SLOW-4 (elevation 106.93 feet msl), which is situated near the center of the study area. 6.0 RESULTS OF LABORATORY ANALYSIS Total extractable petroleum hydrocarbons (TEPH) were detected in 16 of the 33 soil samples submitted for laboratory analysis. TEPH concentrations ranged fi'om 260 to 9,000 milligrams per kilogram (mg/kg, or parts per million); the carbon chain length of the hydrocarbons detected ranged from Ct6 to C36, which is within the typical range of crude oil. TEPH was not detected in any of the remaining 17 samples analyzed, with a practical quantitation limit of l0 mg/kg. Laboratory results of soit samples are summariznd in Table 1. Boring locations and results of labomtory analysis and are plotted on Figure 3. Figure 4 presents cross-sections along the study area, showing analytical results as rcpofted by laboratory testing.

Groundwater was encountered in 8 of the 13 borings, at depths ranging from l3 to 18.5 feet below ground surface. The groundwater surt'ace in well SLOW-4, near the center of the study area, was measured at 14.58 t'eet below grnund surface in June 1996. 8.

Water Board staff received your comments on the proposed closure dated September 26,2014, and October 2,2014. Water Board staff provides the following responses to your questions and comments: September 26. 2014 comment letter question - How are you going to build infrastructure for property development and not disturb contaminated property? Including improvements on Tank Farm Rd. Water Board Statf Response: The responsible party, Chevron Environmental Management Company (CEMC), retains responsibility for any remaining pollution related to the pipeline leak along Tank Farm Road. lf pollution is encountered during future development or road improvements, CEMC is required to ensure that it is handled properly. CEMC has developed a soil and groundwater management plan which is accessible on the State Water Board's GeoTracker website at the following location: http://oeotracker.waterboards.ca.qov/requlators/deliverable documents/9739729166/Tank%20F arm%20Road%20Pipeline%2OSGMP Final.pdf September 26. 2014 comment letter question - Why does everyone let Unocal/Chevron do the testing and provide the results to the City of San Luis Obispo and the Water Board? Water Board Staff Response: Water Board staff requires all responsible parties in the Site Cleanup Program to pay for site assessment, monitoring, and cleanup. The work that is performed by CEMC must include a signature and stamp of a registered professionalwith applicable experience attesting, under penalty of perjury, that the report is true and accurate. Additionally, all soil and groundwater samples are analyzed by laboratories that are certified by the state. The final work product is always reviewed by Water Board staff to ensure that the work has been done properly. flc, JLlru-Ptt.Hq: Wr-rrrr, cnera I Krtsurttl A, HaxHrr Jn., execurtvt orrtcen 895 A€rovi$la Placs, guits 101, San Luis Oblspg, CA 93401 I www.walerboardg.ca,gov/centrslcoast (f orc"ci ro nancn Mr. Garry Holdgrafer ll -2-December 9,2014 October 2, 2014 comment letter - The two wells located on my property are to be monitored forever according to a settlement from a lawsuit brought against Unocal/Chevron. One well is contaminated and the other is clean. They are not to be touched or removed. Please remove them from any list on Tank Farm Road of wells to be removed. Unocal/Chevron does not have the authority to remove, tamper, touch the wells located on my property unless to do theirrequired test monitoring. Water Board Staff Response: The location of the soil and groundwater pollution is along Tank Farm Road on the north side of your property. Your letter did not mention the existence of a water supply well on your property, but according to City records, your property is not supplied with water from the City of San Luis Obispo. Please provide a map showing the location of your on-site drinking water well and details of well construction if available to enable us to evaluate any risk to your water supply. However, it is our understanding that the wells you are referringto in your letter are groundwater monitoring wells and not drinking water supply wells. Water Board staff requires responsible parties to properly abandon all groundwater monitoring wells after we have determined that investigation and cleanup is completed in order to prevent cross contamination of aquifers by wells that can act as conduits for pollution as they age anddeteriorate. We request that you allow CEMC access to your property so that they may abandon the groundwater monitoring wells, as required by Water Board staff. lf you refuse access, we have the legal authority to require you to remove the wells at your own expense. However, if you have a legal document that requires CEMC to maintain the wells in perpetuity, please provide it to this office by January 5,2015, and we will re-evaluate the requirement for abandonment of the groundwater monitoring wells. We also want to inform you that we have notified the City and County of San Luis Obispo to ensure that they are aware of remaining soil and groundwater pollution, and we have not received objections from them on the proposed site closure. We plan to proceed with closure. CEMC will continue to be responsible for contamination and a program is in place to address any pollution that is encountered in the future. We hope this letter addresses your concerns. lf you have additional questions, please contact Alison Jones of my staff at Alison.Jones@waterboards.ca.oov or at (805) 542-4646, or John Robertson at (805) 5424630.

Box 1069 San Luis Obispo, CA93406 Dear Mr. Meyer: UNOCAL TANK FARM ROAD PIPELINE; REQUEST TO DESTROY/REPLACE WELLS ON THE LONG-SUBURBAN PARCEL (APN 053-257-022\ On October7,2005, Ms. Diane Kukol of my staff received an electronic copy of a document entitled, Request to Abandon/Replace Wells, Tank Farm Road Pipeline Sire (Document), dated September 29,2005,prepared by Avocet Environmental, Inc. on behalf of Unocal. The subject area, which is in the process of being developed for commercial purposes, is a 7.4-acre parcel that is southeast of the intersection of Tank Farm Road and Long Street, and extends between Tank Farm Road and Suburban Road in San Luis Obispo (APN 053-257-022; henceforth referred to as the Long-Suburban parcel). The purpose of the Document is to propose the destruction of two Unocal monitoring wells and one unidentified (i.e., not associated with Unocal) water supply well on the subject property so that development activities can proceed unhindered by the wells' presence. In addition, the Document proposes installing a single replacement monitoring well after Cornerstone Development accomplishes further development ofttt" site. During an October 12,2005 teleconfeience, Ms. Kukol gave verbal concurrence of' activities proposed in the Document to Mike Rendina of Avocet Environmental, Inc. Based on information provided in the Document, we agree to the destruction of Unocal monitoring wells OMW- and SLOW-9, as well as the destruction of the unidentified supply well'It is our understanding that OMW-3, SLOW-9, and the supply well will be destroyed in accordance with the Califomia Department of Water Resources Bulletin 74-8t and supplemental Bulletin 74-90. Specifically, OMW-3 and SLOW-9 will be destroyed in accordance with the following procedures:1. Aboveground steel monument and surface concrete will be removed;2. Well casings and filter packs will be filled with bentonite cement grout that is emplaced under pressure to ensure the wells are properly filled and sealed;3. The upper five feet of well casing will be removed and the resultant void will be backfilled with bentonite cement grout. Because construction details for the unidentified supply well cannot be verified, the well will be destroyed by removing all material within the original borehole (including the casing, filter pack, and annular seal) via overdrilling to the total casing depth. The resulting hole will then be filled with appropriate sealing material. California Environmental Protection Agency ffi RecycledPaper Mr. Chris Meyer Mr. Rick Rittenberg'Unocal Corporation P.O.

You indicated you wanted to know if the Water Board would be requiring cleanup of petroleum hydrocarbon- Lontaminated soil from the property, and if so, how would that cleanup impact proposed development' During the telephone conversation, you told my staff that you understand the history associated with this prop"iy is as iollows: (1) petroleum hydrocarbons have been detected in soil along portions of Tank irarm Road resulting from buried Unocal pipeline leaks, (2) characteization of the extent of hydrocarbons due to the presence of these pipelines had indicated that soil contamination existed in the vicinity of the property, but not directly on ihe subject property, and (3) during drilling of a geotechnical boring on the routh-"Lntrul portion of ihe propertron March 13,2005, petroleum hydrocarbons were detected in soil at a depth of approximately li.s f""tbelow ground surface (bgs). My staff confirmed this information is corrict anO itrat Unocal had reported the March 13, 2005 detection to staff in mid-March 2005. Staff has recently reviewed a report provided by Unocal dated April 8, 2005 (Site Assessment Report, Long-Bonetti property, by AvoCet Environmental, Inc.) in which a subsequent characterization of the exteirt of petroleum hydrocarbons on the subject properfy was described. As noted in the report, petroleum hydrocarbons in soil on the Long-Bonetti property appear to be the due to leaks from the bnocal pipeiines that extend along a portion of Tank Farm Road. Water Board staff concurs with this conclusi,on. Based on this review, as well as previous staff involvement with petroleum hydrocarbon contamination along Tank Farm Road, we do not intend to require Unocal or the current landowner to cleanup the petroleum hydrocarbons in soil on the subject property. Additionally, we do not object to development and associated construction on the property. These decisions area based on the fact that although petroleum hydrocarbon contamination apparently due to releases from Unocal pipelines beneath Tank Farm Road occurs on the subject properfy, the contaminated soil occurs between approximately 14 and 2g feet bgs. Based on typical construction activities that have occurred elsewhere along Tank Farm Road, onsite construction activities are not expected to extend as deep as 14 feet bgs. In the unlikely event that soil containing petroleum hydrocarbons is encountered during construction activities, onsite workers should follow ari appropriate health and safety plan. Please notify both the Regional Board and san Luis obispo city Fire Department if such soil is encountered.

Box 1069 San Luis Obispo, CA93406 Dear Mr. Almas: UN9CAL TANK FARM ROAD PIPELINE; REQUEST TO DESTROY/REPLACE WELLS ON THE LONG-SUBURBAN PARCEL (APN 0s3-2s7-022) On October 7,2005, Ms. Diane Kukol of my staff received an electronic copy of a document entitled, Request to Abanclon/Replace Wells, Tank Farm Roacl Pipeline Slre (Document), dated September ig,2115,prepared by Avocet Environmental, Inc. on behalf of Unocal. The subject area, which is in the pto..s olbeing developed for commercial purposes, is a J .4-acte parcel that is southeast of the intersection of Tank Farm Road and Long Street, and extends between Tank Farm Road and Suburban Road in San Luis Obispo (APN 053-257-022; henceforth referred to as the Long-suburban parcel). The purpose of the Document is to propose the destruction of two Unocal monitoiing wells and one unidentified (i.e., not associated with Unocal) water supply well on the subject property so that development activities can proceed unhindered by ttre- wells' presence. In addition, the Document proposes installing a single replacement monitoring *"ll uft"r Comerstone Development accomplishes fuilher development of the site. During anbctober 12,2005 teleconference, Ms. Kukol gave verbal concurrence of activities propor"d in the Document to Mike Rendina of Avocet Environmental, Inc. Based on information provided in the Document, we agree to the destruction of Unocal monitoring wells OMW- and SLOW-9, as well as the destruction of the unidentified supply well' It is our understanding that OMW-3, SLOW-9, and the supply well will be destroyed in accordalce with the Caiifornia Department of Water Resources Bulletin 74-8I and supplemental Bulletin 74-90. Specifically, OMW-: and SLOW-9 will be destroyed in accordance with the following procedures:1. Abou"g.ould steel monument and surface concrete will be removed; 2. Well casilgs and filter packs will be filled with bentonite cement grout that is ernplaced under pressure to ensure the wells are properly filled and sealed; 3. The upper five feet of well casing will be removed and the resultant void will be backfilled with bentonite cement grout. Because construction details for the unidentified supply well cannot be velified, the well will'6e destroyed by removing all rnaterial within the original borehole (including the casing, filter pack, and annular: seal) via Jverdrilling to the total casing depth. The resulting hole will then be filled with appropriate sealing material' C alifornia E nviro nm ental Pr otection Agency ti Req'cled P,Pe, Mr. Bill Almas October 19,2005 We also approve the future installation of a single replacement monitoring well in the vicinity of OMW-3. We are pleased that the proposed construction of this well will accommodate a design to prevent the well from going dry during low-water periods, and the well screen from becoming submerged during high-water periods. Because this replacernent well will likely not be installed until site development is largely complete, we expect to see a Worlcplan for its installation within approximately one year (by October 2006).

These wells are located on the northern part of the Union Asphalt property at 219 Tank Farm Road. Mr. Ljung indicated that Union Asphalt, along with an adjacent property owner, intend to widen Tank Farm Road and install several public improvements in the area containing the two monitoring wells. Because the wells are in the right-of-way of proposed sewer and water lines, Mr. Ljung and Union Asphalt personnel are concerned that construction activities would interfere with the integrity of SLOW-2 and -3. Mr. Ljung indicated that a work plan would be provided to the Regional Board describing the well destruction and removal activities. The work plan (prepared by Earth Systems Pacific and dated February 25,2002) was received on February 26,2002. Because Union Asphalt intends to begin construction activities during the week of March 4,2002, it is noted in the work plan that Unocal would like to conduct the well destruction and removal on Monday, March 4,2002. The purpose of this letter is to officially approve the February 25, 2002 worli plan provided that only wells SLOW-2 and SLOW-3 are destroyed and removed (and not also well OMW-7, as noted in the work plan). Please provide us with a report of well removal activities within 60 days of removal activity completion. An appropriately registered professional must certi! that the wells were destroyed according to California standards. California Envfuonmental Protection Agency#Recycled Paper -) Mr. Ken Smith February 28,2002 Although quarterly groundwater monitoring data have not indicated many detections of petroleum hydrocarbon compounds since wells SLOW-2 and -3 were installed in 1989, a single well must be installed to replace these two wells after Union Asphalt construction activities are completed.

You indicated that the San Luis Obispo City Fire Department required Regional Board review and approval because of petroleum hydrocarbon contamination detected in soil and groundwater along and adjacent to a section of Tank Farm Road in the vicinity of the Farm Supply property. Specifically, you were told by the San Luis Obispo City Fire Department to "obtain written approval from the Central Coast Regional Water QualityControl Board for construction on this parcel." Please be advised that we do not object to construction and development on the property for the following reason: although petroleum hydrocarbon contamination due to releases from a Unocal pipeline beneathTank Farm Road occurs on the Farm Supply property, the contaminated soil occurs between approximately l5 and 40 feet below ground surface (bgs). Based on information provided by Ms. Christi Fry of Triad/Holmes & Associates on October 9,2002, onsite construction activities are not expected to extend as deep as 15 feet bgs. In the unlikely event that soil containing petroleum hydrocarbons is encountered during construction activities, however, onsite workers should follow an appropriate health and safety plan. Please notifu both the Regional Board and San Luis Obispo City Fire Department if such soil is encountered. With respect to ground water monitoring well SLOW-1, you were instructed by the San Luis Obispo City Fire Department to "[o]btain approval in writing from the Central Coast Regional Water Quality Control Board and San Luis Obispo County Division of Environmental Health prior to removal or relocation of the existing monitoring well." In atelephone discussion with Unocal on August 19,2002, we gave our verbal approval to Unocal to destroy the well. In addition, we provided Unocal with a letter, dated October 10,2002, documenting this approval (a copy of this letter has also been sent to you). We are not requiring Unocal to replace the well at another location on the Farm Supply property at this time; however, we reserve the right to require well installation if conditions associated with the Tank Farm Road Pipeline contamination warrant it.

Even the risk to utility workers, the only group who may potentially be exposed to the crude oil during excavation, was studied and shown to be insignificant' Since the poientialexists for crude oit-imp-acteo soil to be exposed during future construction' a representative of the City of San Luis Obispo requested that a generalized Health and Safety Plan (HASP) b9 prepared io provide contractors *ittt u source o}information on health and safety issues and iecommended soil handling practices. It is the objective of this document to: . pro wde appropriaely traine| licensed contractors with chemi cal' hazard information for the crude oil impacted soil. rnis information was developed with the intent that it be attached as an addendum to a contractor's sitdtask-specijic HASP, thus aiding in the protection of the health, safety and welfare of workers who may potentially encounter oily soil; I provide contractors with the information necessary to fulfill State and Federal hazard communication (HAZCOIv! requirements for workers who may potentially be exposed to oily soil; and Mnimize any further threat to the environment due to inappropriate handling of oily soil, if encountered. 2.0 LIMITATIONS a The information contained in this HASP is provided for guidance purposes only and is not intended as a zubstitute forthe development of a sitdactMty-specific HASP which should be prepared by any entity conducting work in *y -*.

The extent of oily soil, free oil on ground water and dissolved hydrocarbons in ground *ut., irave been delineated in several studies (Brown and Caldwell, 1988' 1989; Dames & Moore (D&lo, 1990; Earth Systems consultants @SC), 1996a' 1996b)', Recent investigations by Earth Systems Consultant, huu, improved the definition of the area in which hydrocarbon concentration exceeds 100 mg/kgin the soil within the San Luis obispo city limits (ESC, lgg6a,lgg6b). Figure I (attached)-shJws the site location and the approximate extent of impacted soil. The top of oily soil ranges from 8 feet deep near Tank FT". Road to 15 feet deep near the northern and southern plume riargins (ESC, D9Za, lgg6b,l996c). Soil impacted by crude oil typically displays an olive gray color - as opposed to brown which is common elsewhere' The impacted soil generally has a discernable hydroc"iuon odor and heavily impacted areas may exhibit small drops of dark brown oil in the soil Pores. 3.1 Chemical Hazard ,,All sabstances are poison; there is none which is not poison. The right dose dffirentiates a poisinfrom a remedy" (Paracelcus, I493-I54I) Risk is a function of toxicity and exposure. For a toxic substance to pose a threat, the potential for exposure must exist. lf th.r. is no probable route of exposure, there is no risk. Potential routes of .*porup include ingestion, inhalation, dermal absorption and injection' Crude oil is a naturally-occurring (i.e., unrefined), complex liquid consisting almost entirely of hydrocarbons (i.e., varying mixtures oi ttre elements hytlrogen and carbon (hydrocarbo-n)' Tl' physical properties ana chemical composition (toxicity; of cruae oil vary markedly, depending on its ENGLAND & ASSOGfuATtrS HEALTH & SAFETY PI.AN Unocal Trnk Farm Road Plpellne l,eak Slte Page 37-ryn San Luls Oblsno. Csllfondr source. The primary constituents of crude oil fall into three major categories: paraffins, naphthenes, and aromatics. Many crude oil components, such as parafffins and naphthenes, are generally not considered to be highly toxic (Amdur ;t al., tggt;Clayttn and Clayton, l98l) and are not typically included as chemicals of concern in assessments of health hazard' The constituents of primary concern for hazard assessment are contained in the aromatic fraction' The most toxic known compounds found in the aromatic fraction are benzene and the suspected carcinogenic polynuclear arbmatic hydrocarbon (PAH) compounds (carcinogens are chemicals thought-capabie of causing cancer if administered in large or long-lasting doses). Noncarcinogenic compounds that may alsJ be of concern include toluene, ethylbenzene, rylenes, naphthalene, and other noncarcinogenic pArI compounds. In addition to their potential toxic effects, benzene, toluene, ethyl benzene anJrylenes (BTEX) compounds are of concern because of their volatility and mobility in the environment, properties that increase the likelihood of exposure' BTEX compounds have been detected only infrequently in soil, and where they have been detected, their concentrations have been very low pfeX'-.0.04, <0.18, <0.07 and <0.34 m/kg) @ames & Moore (D&M), 1990). A more recent investigation found no detectable BTEX in ten samples with measurable crude oil concentrations partn Systems Consultants, 1996)' These very low concentrations are not considered sufficient to pose significant health and/or safety hazards to utility workers (England & Associates, 1996a). Aii quality monitoring for volatile hydrocarbons during construction is not necessary. Monitoringfor air quality concerns unrelated to the crude oil problem (i.e., oxygen deficiency, e;.) are the responsibility of the entity conducting the work' Of eight soil samples analyzed for PAHs, twelve PAH compounds were detected (D&M, 1990)' Seven of these "r" ,urp."ted human carcinogens and five are not. PAHs have very low vapor pressures and adsorb strongly to soil. Therefore, inhalation of vapors is not a likely route of L*por*". potential routes of .ipo.ur. to PAHs involve ingestion of soil, absorption through the skin tAirmaf absorption), and injeaion (Aitty cuts or puncture wounds). Although it has been shown that the pAH concentrations in soil are too low io constitute a significant health threat, safe work practices and good personal hygiene can substantially reduce the potential for even low levels of exposure to PAHs. Following is a complete list of hydrocarbon constituents detected in the crude oil impacted soil, their associated Chemical Abstract Service Number (C.A.S.

The MSDS is very broad to cover a wide range of crude oils and is therefore very con;ervative. Furthermore, the r.i. oil at the Tank Farm Road site has been in the ground for at least 60 years and has undergone extensive weathering. The effects of weathering are most profound onih" low-molecular wiight fraction of the petroleum, selectively removing/reducing the more volatile and soluble constituents. Therefore, the weathered crude oil does not possess the flammability hazards described in the MSDS. 3.2 Human Exposure Hazard Analysis A Health Risk Assessment GnA F&A l996al) was conducted to address the potential for adverse health affects as a result of worker "*porur. to oily soil during utility construction' The HRA considered the potential threats to workei health associated wrth inhalation of vapors and air-borne particulate, und direct contact (incidental ingestion and dermal contact) with oily soil during construction. The risk appraisal assumed conservatively high levels of expo.sure (worst-case soil concentrations) for ten (Ig)^days (much longer than is typically required for utility installation) so as to not underestimate the threat. The results of the HRA indicate that the site is safe for utility workers under the conditions considered. Both potential carcinogenic risk and noncarcinogenic hazardare considered acceptable under California Department of To>Ic Substance Control and United States Environmental Protection Agency guidelines. It is important to note that the assumptions and approaches used in developing the HRA were designed to ensure that potential risks were not underestimated. For example, risk assessments typically utilize average concentrations to estimate chronic risks associated with long- term exposur.a, t o*.uer, the ru*irur reported concentrations of hydrocarbons in soil were used in the calculation of potentiar rists. Any attual risks associated with the Tank Farm Road Pipeline site are likely to be much less than estimated in the HRA analysis, and may, in fact, be zero' 4.0 RECOMMENDATIONS IN THE EVENT OILY SOIL IS ENCOUNTERED In the event oily soil is encountered we recommend that the following measures be implemented: Beruo @) lluorsnthene Benzo (k) lluoranthene Benzo(gJt$ perYlene Chrysene IXbenz (a'h ) anthrscene Ethyl benzene Fluoranthene Indeno (l JJ-c'd) PYrcne Phenanthrcne P;rrene Toluene (Melhyl benzene, Berzene, methyl') Xylene (o.,m-, p isomers) Yes Yes No Yes Yes No No Yes No No No No 0.2 0.063 0.32 0.82 0.27 0.07 2.8 4.47l8 1.8 0. l8 0.34 ENGLAND & ASSOGIATtrS HEALTH & SAF'ETY PLAN Unocal Tank Farm Road Ptpellne Leak Slte San Page 5 ENGLAND & ASS@GOATES Notify (Jnocal: Notiry Unocal immediately at (805) 348-3].26' Be prepared to provide an accurate work area location (i.e., nearby intr.r"riions, proierty address or map page and grid locatiof) and description of the *ork being perfiormed. Unocal may, at its discretion, provide a technician to document the conditions encJuntered and oversee soil segregation and stockpiling' Establish Designaled work Areas: Access to work areas surrounding an excavation exposing oily soil and the oily soil stock pile should be controlled by erecting temporary.barriers' Only authorized workers wearing "pp.ou.o personal protective equipment shall be permitted within the designated work area. Eating, irinr.ing and smoking should be discouraged within the designated work area' penonal protective Equipment: Although the health risk assessment demonstrated that the potential for adverse health effects as a result oT.onrtru.tion in the oily soil area is negligible, personal protective measures should be implemented to minimize contact with oily material. To achieve this goatall work gfollbe conducteil in Level D penonal protective equipment (PPE)' Level D PPE includes: Iong pants and long-sleeved shirts, iteel-toed boots, gloves, hard hot and safety glasses' Personal Hygiene: To avoid accidently ingesting oily soil, eating, drinking and smoking should be discouragedwithin the designatedwirk-*ro. -otly soil may be transferred to food by dirty hands or air-bome dust may settle o;food containers (i.e., ioda cans) resulting in unintentional ingestion' hior to eating, fuinking or smoking and at the'enil of the u'ork day, thoroughly wash hands and face with soap and waten Minimize Erytosure: To the extent possible, minimize physical entry into any trench or pit exposing oily soil. Material Handling: Minimize the amount of oily soil excavated. Excavate only what is necessary to complete the task at hand. visibly oily soil should b.e stockpiled separately_ from other excavated material. The material should be stoct<pited onto plastic sheeting and covered.by securely anchored pf"*i. sheeting. The purpose of covering the oily soil is to minimize the potential for human contact, not to suppress 1rupor, (since volatile constituents are not present). Therefore, if the oily soil is to be moved later the **. duy, covering may be unnecessary. Oily soil should not be placed back into any excavation without written authorization' 5.0 OTHER REQUIRED PLANS As was pointed out previously, the purpose of this document is to provide chemical hazard and material handling information for partiis eicavating within the area of impacted soil.

Your request was discussed with Frank DeMarco, of this office, on iunuury 23 and 26, lgg8. We concur with your request to extend the submittal dates for Tasks 2 through i andg to March 4. 1998. However, Task 8's compliance date of February Z,Igg1,is still in effect. Please note, Task 8 of our January 12 letter is restated as follows: ..Until Task l0 a), d) and e) are completed, take interim measures to prevent aquatic and tegestrial uni.uir from getting into areas affected by petroleum hydrocarbons, to be in- place by and continually maintained after&b@I99,E'" We acknowledge Unocal has started the process of complying with Task 8 by attempting to dewater tank number 7. However, you indicated problems were experienced with the dewatering equipment and saturated soils .uuring access problems. we encourage unocal to aggressively pu.ru" implementation of Task 8. Please notify us when you have completed the dewatering of iank 7 und huu. implemented other interim measures' on or before February 2,1998' Your request for clarification on Tasks 6 and 7,is provided as follows: Task 6: We are interested in photographs that will aid us in understanding the historic seasonal wet and dry cycles associated with this site. Task 7: It was our understanding Unocal had digitized maps of this site's wetlands and other surface water features. You indicated this is not th" case.

These wells are located on the Spice Hunter property on the south side of Tank Farm Road. In addition to the wells' removals, Mr. Ljung indicated Unocal's desire to install an additional four monitoring wells within the plume on a variety of properties located south of Tank Farm Road. Mr. Ljung indicated that work plans to address both well removal and installation had been presented to the Regional Board in February 1999 and May 1998, respectively. Our comments are noted below. Work Plan (Work Plan 1) for Monitorine Well Removal (February 24. 1999) 1. We approve segments of Work Plan 1 indicating the removal of 10 ground water monitoring wells (OMW-4, ESP-2, ESB-1, ESB-2, ESB-3, ESP-1, ESP-3, OEW-1, OMW-1, and SLOW-5) from the northeast corner of the Spice Hunter property. 2. Work Plan I indicates that, " . . we propose to remove the wells, and replace them with new monitoring wells once [Spice Hunter] site development has been completed." However, based on the October 6,2000 telephone conversation with Mr. Ljung, it is our understanding that Unocal will remove the l0 noted wells and install the four wells proposed in the Work Plan for Monitoring Well Installation <iuring the same field mobiiization efrcrt. We recommend that rapid instaiiation oi new wells capable of being monitored during the fourth quarter 2000 monitoring event is desirable to waiting until The Spice Hunter's expansion is complete, especially because the property is not currently under any visible development 3. During the October 6, 2000 telephone conversation, Mr. Ljung noted that nine wells on the Spice Hunter property would be removed. Note that Work Plan 1 describes the removal of 10 wells. If any deviations from the February 24, 1999 plan are intended, additional approval must be obtained from the Regional Board prior to initiation of field activities. 4. Please provide us with a report of well removal activities, including the status of the damaged wells (if possible) and the volume of oil removed via a vacuum truck from each well. This report should be provided within 45 days of removal activities. An appropriately registered professional must certif, that the wells were destroyed according to California standards. California Environmental ProtectionAgency f 8 RecycledPapdr 2DMr. Ken Smith October 23,2000 Work Plan (Work Plan 2) for Monitorine Well Installation (Mav 18. 1998) 1. We approve the installation of four wells at the locations proposed in Work Plan2 2. Due to the nature of the contamination within the plume and the fluctuating ground water table, the new wells should be constructed to avoid submerged screens. Therefore, the top of the screened interval for the well proposed southwest of SLOW-3 should be closer to the ground surface than 10 feet (we recommend approximately five to seven feet below gfound surface). 3. All new wells should be surrounded by appropriate confrols (e.g., at least three brightly colored, stable steel pipes, etc.) to prevent personal. or construction vehicles from damaging the wells, as occurred with OMW-4 and ESP-2. 4- These new wells should be incorporated into the quarterly ground water monitoring already established for the site. 5. If any deviations from the May 18, 1998 plan are intended, additional approval must be obtained from the Regional Board prior to initiation of field activities. Lastly, please provide us with a schedule for the well removal and installation activities. If you have any questions, please call Diane Kukol at (805) 542-4637 or Harvey Packard at (805) 542-4639.

A brief explanation is required for all answers except "No Impact" answers that are adequately supported by the information sources a lead agency cites in the analysis in each section. A "No Impact" answer is adequately supported if the referenced information sources show that the impact simply does not apply to projects like the one invotved (e.g. the project falls outside a fault rupture zone). A "No Impact" answer should be explained where it is based on prolect-specific factors as well as general standards (e.g. the project will not expose sensitive receptors to pollutants, based on a project-specific screening analysis)' 2. All answers must take account of the whole action involved, including ofGsite as well as on-site, cumulative as well as project-level, indirect as well as direct, and construction as well as operational impacts. The explanation of each issue ihould identify the significance criteria or threshold, ifany, used to evaluate each question. 3. "potentially Significant Impact' is appropriate if there is substantial evidence that an effect is significant. If there are one or more "P-otentially Significant Impact" entries when the determination is made, an EIR is required. 4. "potentially Significant Unless Mitigation Incorporated" applies where the incorporation of mitigation measures has reduced un .ffJat from ,'potentially Significant Impact" to a "Less than Significant Impact." The lead agency must describe the mitigation measures, und bri"fly explain how they reduce the effect to a less than significant level (mitigation ."usui"r from Section 17, "Earlier Analysis," may be cross-referenced). 5. Earlier analysis may be used where, pursuant to the tiering, program EIR, or other CEQA process' an effect has been adequately analyzed in an earlier -etR or negative declaration. Section 15063 (c) (3) (D) of the Califomia Administrators iode. Earlier analyses are discussed in Section l7 at the end of the checklist. 6. Lead agencies are encouraged to incorporate into the checklist references to information sources for potential impacts (e.g. general plans, zoning ordinances). Reference to a previously prepared or outside document should, where appropriate, inciude a reference to the page or pages where the statement is substantiated. 7.

X Evaluation a) The Circulation Element of the General Plan identifies Tank Farm Road as a road of high scenic value along the projectsite frontage. There is no scenic vista near the project site, but the views of the Santa Licia range looking Jast from theproject site are relatively unobscured. A significant effect would occur if the proposed development blocks these views, orotherwise limits them significantly. Based on staffs evaluation of the project plans ana visits to the project site, it does notappear that these views would be substantially blocked. Photos of the viewshed taken from the vicinity oithe prolect site areattached to this Initial Study for reference. The proposed development is set back significantly (approximately g6 feeg flomthe Tank Farm Road corridor. This setback will insure that viewi to the Santa Luciaiange wiil bsmaintained'for pedestriansand vehicles traveling along this portion of Tank Farm Road. The proposed building height of 35 feet complies with thestandards in the Higuera-Commerce Park Specific Plan. Architecturil plans indicate ihat a-rchitectural roof features, whichalso serve to screen mechanical equipment, extend to a height of 42 feet. The Higuera-Commerce park Specific plan statesthat the Architectural Review Commission can approve such architectural features up to u maximum height of 50 feet. b), c) The project site is primarily flat, vacant land. There are no trees, rock outcroppings or other significant types of scenicresources on the property. The project site is part of a recent subdivision in an area designated forlndustrial development.Development is subject to review by the City's Architectural Review Commission, whiih regularly reviews projects andmakes changes to project proposals to insure that new structures are architecturally compatiUt&itn Uuitding sites"and withexisting structures on adjacent properties. d) The project includes outdoor recreation facilities that will be lit at night, The parking lot will also be lit at night. TheCity's standard for parking lot lighting provides for maximum illumination levels of l0 foorcandles at the base oflhe lightand prohibits light in excess of one foot-candle from spilling over the property line. Glare light is typically reduced throughstandard requirements to shield lights and recess light rourc"s within light fixtures. The Architectural-Review process will beused to insure compliance with this standard. Conclusion The project is proposed along a scenic corridor as identified in the Circulation Element of the General plan. Staff believesthat the setback proposed for the building, approximately 80 feet fiom the Tank Farm Road property line, will insure thatviews along the Tank Farm Road corridor are preserved. Architectural Review is required to approve the proposed buildingheight of 42 feet. The Architectural Review Commission will also evaluate the applicant's lighting p.oporuiund will establishconditions of approval to insure that City standards are met and that glare and spiit tignt are ieduced to a minimum. planningstaff routinely uses the building permit plan check process to insureiomplianci wittr aRC approval and City standards.

However, this project will not conveft the land from a non-agricultural use because the land is not inigated or used as farmland. The Farmland Mapping and Monitoring program of the California Resources Agency classifies the project site as Urban or BuilrUp Land, which is defined as-,.lanJoccupied by structures with a building density of at least 1 unit to 1.5 acres, or approximately 6 structures to a l0-acre parcel." b) The property is within the Higuera Commerce Park Specific Plan area. The specific plan was adopted in 1979 and the project ,i. iru, teen planned for development with industrial uses since that time. The property was subdivided in 1996' At the time of the subdivision, frontage improvements, including sidewalks, curbs and gutters were installed. The site was rough graded in anticipation of developrnent. There is no Williamson Act contract in effect on the project site' c) Agricultural uses have not occurred on the properry since the site was subdivided. There are no other changes caused by the prlject that could result in conversion of ai;ac"nt parmland to non-agricultural uses. All of the undeveloped areas in the vicinity of the project site are within other special planning areas such as the Margarita Area and the Airport Area, or are zoned for conservation. The continuation ofagricultural uses in these areas will be evaluated as part ofthe planning process for those areas. This project is not precedent sJtting in any way that might entitle agricultural land to be developed with urban uses. The specific plan amendment proposed uy ttre applicant would allow health clubs in the whole Special Industrial District of the specific plan area, but there is no agricultural land in this area' Conclusion The Farmland Mapping and Monitoring program of the california Resources Agency classifies the project site as Urban or Built-Up I-and. Tire prlject site has been inside the City Limits of San Luis Obispo and designated for development for over l5 years. There are no Williu-son Act contracts that would be effected by the development proposal or by the specific plan amendment. No further mitigation is required. 3. AIR ALITY.

The 1995 Clean Air plan (CAp)for San Luis Obispo Countywas developed and adopted by the Air pollution Control District (APCD) to meet that requ irement. The CAP is acomprehensive planning document designed to reduce emissions from traditional industrial and commercial sources, as wellas from motor vehicle use. Land Use Element Policy 1.18.2 states that the Ciry will help the APCD implement the Clean AirPlan. One way the City helps the ApCD implement the Clean Air plan is through the development review and environmentalrevlew processes. According to the Air Pollution control District's (APCD) "CEQA Air Quality Handbook," land uses that cause the generationof I0 or more pounds per day (PPD) of reactive organic gases, oxides or nitrogen, sulfur dioxide, or hne particulate matterhave the potential to affect air quality significantly. Baseld on irip generation data on health clubs from the Institute ofTransportation Engineers, Trip Generation Manual, the City's RssJciate Transportation Engineer has determined that theproject could generate 1,7-20 Average Daily Trips. _ This number of trips exceeds the first tier emissions threshold defined bythe *CEQA Air Quality Handbook" (emission levels of reactive organic gases, oxides or nitrogen, sulfur dioxide, or fineparticulate matter between l0 and 25lbs/day) and would require mltigation. Parcel Map sl-o 9l-152 (which created the current configuration of the project site and bordering properties) was recordedon November 5ft, 1998' one of the City requirements of the rup upp.ouul ii referenced by Note 4 on the final map (attachedfor reference)' The note relates to transit support and trip reduction requirements for any new development ofthe parcelscreated by the map. It reads as follows: Final map shall note that trip reduction plans and implementation programs will be required as partof development review of new projects on all lots. Such plans und piogrurns may be submitted byindividual employers or coordinated into a cooperative transpoft;tion rnunug.rn"nt program byseveral or all property owners in the subdivision. Plans ihall include: I designation of acoordinator to administer the program; 2) carpool and public transit information; 3) iircentives foremployees to use altemative transportation, such as secured bike storage, showers and dressingrooms' employer-paid subsidies to employees using public transit, and other measures to theapproval of the Community Development Director. The above requirement is recommended as a mitigation measure of the proposed development. The project plans alreadyinclude significant components of the trip reduction requirement because ,ho*"rr, dressing rooms and bike lockers areinherent to the health club use. Staff has discussed potential mitigation measures with Larry Allen from ApCD whodetermined that the above requirement will adequately mitigate pitential air quality impacts with a program to promote transituse by employees' In addition, the APCD tt.orn-.ni, the use of "n"rgy efficient-inteiior and exterior lighting and plantingof shade trees along southern building exposures to reduce sunmer cooling needs and in parking lots to reduce evaporativeemissions from parked vehicles. c) During project construction, there will be increased levels of fugitive dust associated with construction and gradingactivities, as well as construction emissions associated with heavy-Iuty construction equipment. The city has addressed theseconstruction related impacts through standards in the Grading ordinance. Compliancewith these standards is monitoredduring the building permit plan check process and by field in-spections conducted by Building Division inspectors. d) Outdoor activities proposed as part of the development project include an outdoor swimming pool. Although some odorsare generally associated with chlorine use in such facilities; st;ff does not believe that these odors would be concentrated orobjectionable' The prevailing wind pattern at the project site in not likely to carry chlorine odors to residential areas or toplaces where people congregate.

Energy efficient interior and exterior lighting, including the use of natural day light in interior spaces, is required to reduce air quality impacts at the source. 3.

Conclusion Compliance with the dust management practices contained in Municipal Code Section 15.04.020 V. (Sec. 3307.2) will adequately mitigate short-term impacts relative to construction generated fugitive dust. This section of the Municipal Code is monitored and enforced by the Building Division of the Community Development Department during routine sites visits and inspections at the construction site. A prior approval on the project site requires a trip reduction plan for this development. The requirement is recommended as a mitigation measure for this project. Compliance with the proposed mitigation measures will red-uce long-term air quality impacts to less than significant levels.

The Long-Bonetti Ranch House is located approximately600 feet from the project site, on an 88,000 square foot parcel. A previous-Initial Study of Environmental Impact (City ofSLo Planning Application No. ER 38-89) specifically addressed potential impacts to the ranch house, a Master List HistoricResource. The Initial Study evaluated a tentative map to subdivide the souihern 2l acres of the Higuera-Commerce parkSpecific Plan Area. Mitigation measures that were adopted as part of the subdivision approval incluaed a requirement tomodifu the ranch house lot to include a minimum area of two acrir, a note on the Final Uap aesignating the lot as a sensitivesite, a requirement to preserve and protect the site's historic resources through impiementation of a restoration andstabilization plan, submission of an adaptive reuse plan for the ranch house lot, and-through the establishment of a restorationand preservation fund for the Long-Bonetti Ranch. These mitigation measures were determined to be sufficient to mitigatepotential impacts to the historic resource. The subdivision resulted in the development of Long Street, which separates the project site from the Long-Bonetti RanchHouse' The development now proposed for the project site, in terms of the type and icale of improvements, was anticipatedduring the prior environmental review. The proposed amendment to the Higuera-Commerce Park Specific Plan would have a significant impact to the Long-BonettiRanch House if the amendment provided for the development of health clubs on the ranch house site. However, the Higuera-commerce Park Specific PIan incrudes specific uses for the ranch house propergr, and those will not change with theproposed amendment to the specific plan. b), c), d) The project site itself has been substantially altered through the development of Long Street, frontage improvementson Tank Farm Road and site grading as part of the required subdivision improvements, and ihe project doe-s not r"p.esent asensitive archeological site. There are no known paleontological resources or unique geologic i.uiur", on the project site.The project site consists ofrough graded dirt and no vegetatio; and is substantially bord-ered iy urban uses. The project siteis outside of the areas designated on the City's Burial Sensitivity Map as potential buriat sites. Conclusion Impacts of development of the subdivision to the Long-Bonetti Ranch House were evaluated as part of ER 3g-g9. Approvalof the subdivision included a requirement to preserve the ranch house on a minimum 2-acre parcel and restricts the ringe ofallowed uses on the historic property. The size and scope of development proposed with this project was anticipated with theprior environmental review. No potential impacts have been identified. No further mitigation is required.

Compliance with this ordinance will require the applicant to prepare a plan to show how significant amounts of construction debris will be diverted from the landfill. The oidinance also requires reporting on compliance with the approved plan, which is verified by area recycling companies and through the provision of receipts for recycled materials. c) The project site includes no known mineral resource that would be lost due to the construction of the project.

The edge of this studyarea extends to the westerly city limits line, near Los osos Valley Road. According to a recently conducted geology study(source l6), the closest mapped active fault is the Los osos Fauli, which runs in a northwest direction and is about one mileflom the City's westerly boundary. Because portions of this fault have displaced sediments within a geologically ,"."n, ,in,'"(the last 10,000 years)' portions of the Los osos fault are considered "active". other active faults in the region include: theSan Andreas, located about 30 miles to the northeast, the Nacimiento, located approximately l2 miles to til'e northeast, and theSan Simeon-Hosgri fault zone, located approximately l2 miles to the west. Although there are no fault lines on the project site or within close proximity, the site is located in an area of ..High SeismicHazards", which means that future buildings constructed on the site will moit likely be subjected to excessive ground shakingin the event ofan earthquake. The city of San Luis obispo is in Seismic zone 4, a seismically active region of california and strong ground shaking shouldbe expected during the life of proposed structures. Structures must be designed in compliance wittr se]sinlc design crilriaestablished in the california Building Code for Seismic zone 4. To minimle this potential impact, the uniform-BuildingCodes and City Codes require new structures to be built to resist such shaking or to remain ,tunAing in an earthquake. b), c), d) The project will not result in the loss of topsoil as most of the site will be covered by impervious surfaces or plantedwith vegetation. The safety Element of the General Plan indicates that the project site has a trigtr iotential for liquefaciion,which is true for most of the city. The soils engineering report that is requir.d to b. submitteifo; each proposed structurewill include recommendations for foundations that are lnt.na"a to withstand settlement. The site does not include expansivesoils, as defined in Table l8-l-B of the uniform Building code (1994). Conclusion Development of the site will not alter the site's seismic hazards. Fufure development will be required to comply with theUniform Building codes and city codes which require new structures to be built to resist shaking and to remain standing inan earthquake, and proper documentation of soil characteristics for designing structurally sound buildings is required as partof the building permit process. No further mitigation is required.

Evaluation a) The project does not involve the routine use of hazardous materials other than chlorine for the pool. The development of the poot will be coordinated with the Public Works Department, Industrial Waste Coordinator, through the building permit plan check process. This coordination will insure that there is an adequate means of disposal of pool water. This means that ihe pool must be able to be drained into the City sewer system as opposed to the storm drain system, which is connected to San Luis Creek. b), c), d), e) A leak from a pipeline serving the Unocal Tank Farm area has resulted in the contamination of soil and ground water on the project site and in the vicinity. A Health and Safety Plan for crude oil hazard and materials handling has been prepared on behalf of Unocal to guide development in the Tank Farm Road area. The areas of contamination have been delineated and the applicant has submitted a site plan showing the area of contamination on the property relative to the proposed improvements (attached). According to the Health and Safety Plan prepared by England and Associates, an invironmentil engineering firm, in 1997, "Detailed assessments of the contamination have established that the crude oil does not pose a threat to human health or to the environment." The full contents of the study are attached to this report- The Regional Water Quality Control Board has determined that remediation of the oil is not required at this time. The recommendations of the Health and Safety Plan include a requirement for a site and task specific health and safety plan to be prepared. The purpose of the site and task specific plan is to develop specific procedures in case contaminated soil is encountered during construction. The plan is also to serve as a notice of the contamination to all contractors working on the project. The general Health and Safety Plan provides detailed information regarding the nature of the contamination and p.ouia"r clearlirection on the required contents of the site specific and task specific plan. The site and task specific plan iubmitted by the applicant must be evaluated and approved by the City Fire Marshall prior to the issuance of any development related permits on the project site. f) The project site is within Airport Land Use Plan Area 3 and is listed as a conditionally compatible use. The Airport Land Use Commission reviewed the development proposal for this site and recommended approval with the condition of soundproofing and a requirement to use non-reflective materials for buildings and signs. The Commission believed that the use wis similar in nature to a medium size office building, in terms of the density of people on the site at any one time. The Commission's concerns were mitigated by the fact that the project site is much larger than a typical offrce site and there is much more open area on the lot. The recommended Airport Land Use Commission conditions can be implemented through the Architectural Review process and by planning staff as part of the building permit plan check process. g) The project has been reviewed by the Fire Marshall and will not conflict with any emergency response plan or emergency evacuation plan. h) The Safety Element of the General Plan identifies the site as having a low potential for impacts from wildland fires. Mitigation Measures: 4. A site and task specific Health and Safety Plan shall be prepared and submitted to the Fire Marshall for review and approval prior to any excavation or construction on the project site. The plan shall be in substantial conformance with the general Health and Safety Plan prepared by England and Associates, 1997.

All contractors, subcontractors and utility workers shall have knowledge of and access to the Health and Safety plan beforecommencement of their work at the project site. The plan is to serve as a notice of the contamination to ail contractorsworking on the project. Conclusion The project site is in an area that contains contaminated soil from a crude oil leak. The Regional Water eualiry ControlBoard determined in 1997 that the oily soil on the project site did not need to be removed. Prior to the commencement of anyconstruction related activity on the project site, a site and task specific Health and Safety plan must be prepared by theapplicant and distributed to everyone working on the project site. The use of chlorine for the pool will ue permittea throughthe City's Industrial Waste Coordinator to insure that chlorinated water is not discharged into ttre storm diain system. Theproject has been reviewed and approved by the Airport Land Use Commission with standard safety requirements that will beimplemented during the building permit plan check process.

The Land Use Element states that the iity should have sufficient land aesignitea for services and manufacturing, to meet most demands of the City and some demands of the region. The Land Use Element also states that areas reserved for these uses may also accommodate uses and activities primarily serving area workers. The Service-Commercialzone and the ManufacturingZone are intended to implement General nlan p-olicy for areas designated Services and Manufacturing. The City's ZoningRegulations allow health ctuus Uy right in both of these'zoning districts. The proposed amendment to the Higuera-Commerce Park Specific Plan will not conflici with any land use plan, policy or regulation adopted for the purpose of avoiding or mitigating and environmental effect. b) The project will not physically divide an established community. It would allow for the development of approximately 4 acres of land within an existing subdivision of commercial land. c) The project will not conflict with any applicable habitat conservation plans or natural community conservation plans' Conclusion The project will be developed with the fype of improvements anticipated by the General Plan and Zoning Regulations and will not create any impacts to land use and planning.

Evaluation a), b) The proposed health club can be considered a service or recreational use. The health club will not create a substantialnumber of new professional jobs that would induce substantial population growth in the area. The project will not displaceexisting housing or people. Conclusion The projects presents no impacts in terms of population and housing. X X Evaluation a) The Noise Element of the General Plan provides standards for acceptable levels of noise exposure for certain noisesensitive uses. The closest use listed in the Noise Element to the proposed use is a playground. Development of playgroundsmay be permitted without specific noise studies or mitigation if the Community Noise-Exposure equivaient is tess ttran zoou(Ldn or CNEL). According to the Noise Guidebook, which provides Community Noise Exposure predictions along majorarterial roads in the City, the 70Db noise contour extends 43 feet from the centerline of Tank Farm Road betrveen BroadStreet and South Higuera Street at build-out. The outdoor use areas proposed with this development are well over 100 feetflom the centerline of Tank Farm Road. As a result, the noise exposure associated with this project should be consideredacceptable. b), c) The project will not raise ambient noise levels in the project vicinity substantially. There are no noise sensitive usesimmediately adjacent to the project site. The normal operations of the project do not involve heavy machinery or generatorsother aspects that could expose people to excessive groundborne vibration or noise levels. d) The project is within the Airport Land Use Plan area, but will not expose people to excessive noise levels from aircraftoperations' The Airport Land Use Commission has reviewed and approved the project proposal, providing standardconditions of approval for the development that will be implemented as part of the Architectural Review process. Conclusion Noise levels generated by transportation noise sources will not expose people to unacceptable levels of noise. Users of thefacility will not be subject to excessive noise levels generated by aiicraftbperations. No further mitigation is required. 12. POPULATION AND HOUSING.

This figure is a conservative istimate and it doesn,t take into considerationthe fact that many of these trips are not true destination trips, but are a stop on the way to an ultimate destination, such aswork' The project design also accommodates people using alternative transportation by providing bike lockers, showers anda locker room' The project will not increase traffic'substaniiully in relation to the capacity of Long Street or Tank Farm Road. b) Peak rush hour trips to and from the site are different than for offices or other uses that generate the most significantamount of traffic at the start and end of the normal work day. The traffic generated bv tf,ir project is dispersZd morerandomly over the course of a day, with a heavy lunch crowd similar to restaurants. Based on the number of trips anticipated,the project will not reduce or significantly contribute to reduced levels ofservice on adjacent roads. c) The project is proposed on a lot that has been approved as part ofa recent subdivision. The subdivision was planned, withrespect to the Long Street/Tank Farm Road intersection, to provide for safe maneuvering from the collector street to thearterial street' The project includes a primary driveway on Long Street and another "nt.un"{ approximately 500 feet from theLong/Tank Farm intersection, on Tank Farm Road. This configuration has been evaluated by the City,s principalTransportation Planner who determined that the configuration will noipresent any operational problems on Tank Farm Road. d) The project has been evaluated by the City's Fire Marshall for emergency access. The Fire Marshall determined that theproject meets design standards for access by emergency response personnel. The project will be further evaluated for properexiting and for fire sprinkler system design during the building permit plan check pio."rr. e), 0 The project provides more parking than currently required by the Cify's Zoning Regulations by approxi mately 22parking spaces and will not result in parking deficiencies. Rlternative transportation *itt U. supported through the projectdesign as well as through participation in an incentive program for employees that use transit, as required by therecommended Air Quality mitigations and the parcel map uppiouit for the subdivision. g) The project will not conflict with the normal operations of the Counfy Airport. The project has been evaluated by theAirport Land Use Commission, which approved the proposed use. Conclusion The proposed health club will not have a significant impact on traffic or transportation systems. The project is bordered by acommercial collector street and major arterial thoroughfare and the streets are designed to accommodate the anticipatedadditional trips generated by the project. The heaviest iimes of use of the health club a-re expected to differ from the heaviestA'M' and P'M' peak traffic hours. There are no unsafe design features of the project, as Long Street has recently beendeveloped as part of the subdivision of the property. No significant impacts have been identified.

Comments note that the project is subject to water impact fees which were adopted to ensure that new development pays its fair share of the cost of constructing the water supply, treatment and distribution facilities that will be necessary to serve it. c) The City has adopted Water Allocation Regulations to insure that increased water use by new development and land use "irung", do not jeopirdize adequate water service to current and new customers. To receive an allocation, the developer will need to retrofit ihe plumbing oiexisting structures to save twice as much water as the projected annual demand. Compliance with the provisions of the Water Allocation Regulations and the water impact fee program is adequate to mitigate the effects of increased water demand. The City Water & Wastewater Management Element projects the City water needs at its ultimate build-out of 56,000 people. The project site is included in the anticipated build-out, because it was in the Urban Reserve at the time the element was adopied. Water usage for a health club with aquatics is estimated at .26 acre feet per 1000 square feet of gross floor area (per y.ui). For the totaiproject, the annual water usage is estimated at 12.22 acre feet (.26*47). The 2001 Water Resources ir.pott indicates that ihe;e is currently 142 acre feet of water available to allocate to in-fill development (development within the 1994 City Limits). d) The City wastewater treatment plant has adequate capacity to serve this development. The existing sewers in the vicinity have sufficient capacity to serve thi development. Impact fees are collected at the time building permits are issued to pay for capacity at the Cily,s Water Reclamation Facility. The fees are set at a level intended to offset the potential impacts of the project. e), f) Background research for the Integrated Waste Management Act of 1989 (A8939) shows that Californians dispose of roughly 2,5b0 pounds of waste p". rnonih. Over 90%6 of this waste goes to landfills, posing a threat to groundwater, air quulity, and puilic health. Cold Canyon landfill is projected to reach its capacity by 2018. The Act requires each city and county in Cajifornia to reduce the flow of materials to landfills by 50% (from 1989 levels) by 2000. To help reduce the waste stream generated by this project, consistent with the Cify's Source Reduction and Recycling Element, recycling facilities must be accommodated on the'project site and a solid waste ieduction plan for recycling discarded construction materials must be submitted with the building iermit application. The project should include facilities for both interior and exterior recycling to reduce the waste stream generated by the project consistent with the Source Reduction and Recycling Element. lssues, Dis cussion and Supporting lnformation Sources ER #60-01 Sources Potentially Significant Issues Potentially Significant Unless Mitigation Incorporated [,ess Than Significant Impact No Impact Mitisation Measures 6' The final project shall be designed to include several convenient locations for the collection of recyclable materials withinthe project for health club users and adequate room within the garbage enclosures to accommodate a iecycling ,".uil" fron,,the local garbage company. Conclusion No impacts have been identified relative to water service or supply, wastewater service or capacity at the Water ReclamationFacility, or storm drainage, Potentially significant impacts have blen identified relative to sotia waste disposal. The City hasrecently adopted a construction related recycling ordinance to insure recycling of construction debris.

Even the risk to utilitv workers, the only group who may potentially be exposcd ro the crude oil during excavation, was studied and shown to be insignificant Since thc poiential eisrs for crude oil-impicted soil to be exposed during future construction, a representative oi the City of San Luis Obispo requested that a generalized Health and Salety Plan (HASP) be prepared io provide contractors with a source of information on health and salety issues and recommended soil handling practices It is the objective of this document to. . pro wde appropriaely trained, licensed contractors with chemical hazard information lor the crude oil impacted soil This information was developed with the intent that it be attachecl asanatfulentlum to a contractor's site/tusk-specifc HASP, thus aiding in the protectioll ol rhe health, safetv and welfare of workers who may potentially encounter oily soil, . provide contractors with the information necessary to fulfill State and Federal hazarcl communicarion (HAZCOM) requirements lor workers who may potentially be exposed to oily soil; and . \linimize any further threat to the environment due to inappropriate handling of oill'soil, i1' encountered 2.0 LI}lITATTONS 'the inlornration contained in this HASP is provided for guidance purposes only and is not intended as a substiture for the development of a site/activity-specific HASP which should be prepared by anl' enriry conducting work in any area Firms requiring workers to excavate within the described vicinitl" lrusr ensure thar: l) the work is conducted in accorcjance with all Federal, State, County and Citr" requirentenrs; and 2) their employees are working under, and in accordance rvith. the firnt's Injury & lllness prevention program (llPP), Codes ol Safe Practice, Hazard Comntunication Prograttl tl-{..VCOiv,{), and Emergency Response Plan These health and saf'ety programs, codes and plarts alc rhe nunimum required of an excavation contractor by CaUOSHA pursuant to Title 8 of the Calilornia Code of Regulations.

The extent of oily soil, free oil on ground w'ater and dissolv'ed hvdrocarbons in ground water have been delineated in several studies (Brown and Caldwell, 1988, 1989; Dames & Moore (D&M), i990; Earth Systems Consultants (ESC), 1996a, 1996b). Recent invesrigatrons by Earth Systems Consultants have improved the definition of the area in which hydrocarbon concentration exceeds 100 m/kg in the soil within the San Luis Obispo City limits tESC. 1996a, 1996b). Figure I (attached) shows the site location and the approxinrate extent ot impacted soil -['hc top of oily soil ranges lrom 8 f-eet deep near Tank Farm Road to l5 fbet deep near the nortlterrr and southern plume margins (ESC, 1996a, 1996b, 1996c) Soil impacted by crude oil ty,picallr. displavs an olive gray color - as opposed to brown which is common elsew'here The inrpacted sotl eenerally has a discernable hydrocarbon odor and heavily impacted areas may exhibit sniall drops ot' dark brown oil in the soil pores. 3.1 Chemical Hazard "All ybstances are poisotr, there is rtorre which is rtot ltoisctrt. 7'he right do.se cltfferentiates a poisott from a rentedy" (Paracelcus, 1493- l54l ) Rrsk is a function of toxicity and exposure For a toxic substance to pose a threat, the potential lor e\posure must exist If there is no probable route of exposure, there is no risk Potential routes crl r'\posure include ingestion, inhalation, derrnal absorption and injection CrLrde oil is a naturally-occurnng (i e, unrefined), complex liquid consisting alntost entirely ot lrrdrocarbons (i e , varying mirtures of the elenrents hydrogen and curbon (h-y'drocurbon) l'hc phvsrcaJ properties and chenrical coniposition (toxicity) of crude oil vary markedly, dependine on rts '- , : " ,.=.1.! :,.

In addition to their potential toxjc effects' benzene' toluene' ethl,r berzene and rylenes (BTEX) compounds are of concern because of their volatility and mobilitl' in rhe environment, properties that increase the likelihood olexposure BTEX compounds have been detected only infrequently in_soil, and r'vhere they hal'e been detected' theirconcenrrations have been very low (BTEX. <O 04, <0 l8' <0 07 and <0 3a mgkg) (Dames & \loore (D&iv0, 1990). A more reient investigation found no detectable BTEX in ten santples rvtth nteasurable crude oil concentrations (Eanh systems consultants' 1996) These Very lorr concenrrarions are not considered suftrcient to pose significant health and/or safety hazards to utilit\ *,orkers (England & Associates, 1996a). Arr quality monitoring lor volatile hydrocarbons dunng construction is not necessary Monitoring for air quality concerns unrelated to the cnrde oil problcnr (i e, orygen deficiency, er;.) are the responsibility of the entity conducting the work oieight soil samples analyzed fbr PAHs, twelve PAH compounds were detected (D&NI' 1990) Seven of these ur. ,urp".ted human carcinogens and five are not PAHs have very low' vapor preSSures and adsorb strongly to soil. Therefore, inhalation of vapors is not a likel.v route ol' e\posure potential routes of exposure to PAHs involve ingestion of soil, absorption through the skin (dermal absorption), and injection (dirty cuts or puncture wounds) Although it has been sho*'n that rhe pAH concentrations in soil are too low to constitute a significant health threat, sale work pracrices and good personal hygiene can substantially reduce the potential lor evetr low levels of exposure to PAHs.

The MSDS is very broad to cover a wide range of crude oils and is therefore very consen'ative. Furtherrnore, the crude oil at the Tank Farm Road site has been in the ground for at least 60 years and has undergone extensive weathering The effects of weathering are most prolound on the low-molecular weight fraction of the petroleum, selectively removing/reducing the nrore volatile and soluble constituents Therefore, the weathered crude oil does not possess the t'lammability hazards described in the iv{SDS 3.2 Human Exposure Hazard Analysis .{ Health fusk Assessment (FIRA [E&A 1996a]) was conducted to address the potential for adverse health affects as a result of worker exposure to oily soil during utility construction The HR.A considered the potential threats to worker health associated with inhalation of vapors and air-borne particulates and direct contuct (incidental ingestion and dernral contact) with oily soil duringconstruction The risk appraisal assumed conservatively high levels of exposure (!vorst-case soil concentrations) lorten (10) days (nruch longer than is typically required lor utility installation) so as ro not underestimate the threat. The results of the HRA indicate that the site is safe for utility workers under the conditions considered. Both potential carcinogenic risk and noncarcinogenic hazard are considered acceptable under Calilomia Department of Toxic Substance Control and United States Environmental Protection Aqencvguidelines It is important to note that the assumptions and approaches used in developing the HR.A, were designed to ensure that potential risks were not underestimated For exanrple, risk assessments typically utilize average concentrations to estimate chronic risks associated with lone- terrn exposures, however, the maximum reported concentrations of hydrocarbons in soil were used in the calculation of potential risks. Any actual risks associated with the Tank Farm Road Pipeline srte are lrkely to be nruch less than estimated in the HRA analysis, and nray, in fact, be zero. {.0 RECO}IiVIENDATTONS TN THE EVENT OILY SOIL IS ENCOUNTERED In the erent oily sorl is encoLrntered we recommend that rlre follorving measures be implentented r3J{i.z A.9!i('i' Attachment 4 HEALTH & SAFETY PLAN t nxal l'uk F'arnr Rogd Pipe ltne Itak Site Page 5.rMuan ?. 199?Sun t-uis Obis xr.

PROJECT AND SITE DESCRIPTION Location:The project is located at the northeast corner of South Higuera Street and Tank Farm Road, in the City of San Luis Obispo. (APN# 053-251-05 I&052) Existing Uses: vacant iingle family dwelling, undeveloped land and row crops Site Area: approximately 4 acres ALUP CONSISTENCY CONSIDERATIONS The proposed project is located in Area 3 of the San Luis Obispo County Airport. At commission's March 21't meeting this Specific Plan Amendment proposal was a discussion item. Occupancy was the main issue and it was determined that the health club use was similar (possibly less people) to a medium density office use. ln, addition there will be a large amount of open space on the property after the project is complete. Noise was not a significant issue due to the type of use (health club). The requested modification to the existing Commerce Park Specific Plan is proposing to add one allowable use to the Special Lrdustrial District portion of the Specific Plan. The allowable uses list submitted by the City is as follows: advertising, public relations, agricultural uses including cultivation offield, vine or tree crops, pasture or grazing and other outdoor agricultural activities, broadcast studios, computer services, credit reporting and collection, delivery, mailing, and postal services, detective and securitlt services, electronic, optical, pharmaceutical and other precision products, parts, instruments or equipment, or similar manufacturing laboratories, other technical facilities for research, testing and processing, medical, and analytical, offices (architects, engineers, industrial design), printing and publishing firms, accessory ffices, machine shops, cafeterias, recreation rooms and similar incidental uses or supportfacilities serving the employees of allowed uses, public utility, Attachment 7 KENNEDY STAFF REPORT. JUNE 2O,2OOI Page 2 construction engineering, soils testing and similar design, healtlt clubs and recreational facilities.A separate use permit will be required to allow the building of the health club facility whi& is a "conditionally compatible" use. The applicant has submitted information regarding this facility with this specific plan amendment application. The planned strucutres are a 38,000 square foot, two story building that would house the indoor fitness facilities such as racquet ball, basket ball, weight training rooms, locker rooms etc.. An adjacent 5,000 square foot building would include an open pavilion tlpe structure designed for audio visual presentations and entertainment with private Kennedy Club Fitness offices above. The two buildings would surround swimming pool and other uses. This development has over 200 parking spaces. your Commission will only review this project once for a-mandatqy determination of compatibility or incompatibility which will refer to the use (health clubs and recreational facilities) being added to the Commerce Park Specific Plan. The proposed health club use and the individual use permit will come before you at alater date, however, there is some concern regarding the open pavilion floor area (i.e. number of people, frequency of functions, noise issues etc.). STANDARD CONDITIONS The Airport Land Use Plan specifies certain standard conditions which may be applied to p.opo."d land uses such as office buildings (the most similar use) in Areas 3 of the^Alijp. The ALUC may apply these as it deems applicable and may require such other conditions as it finds necessary to ensure that the "Conditionally Compatible" uses will be compatible with present and future airport operations. Standard conditions for retail store uses in Area 3 are: 1. sound proofing to reduce noise to acceptable levels 2. low density - to preclude large numbers of people for congregating 3. nonreflective material to be used on buildings and signs. Land uses designated as "Conditionally Approvable" are not compatible with current and projected airport operations unless certain well-defined actions are taken by the Airport LunA Ut" Commission. The requirements which must be met in order for a ..Conditionally Approvable" use to be rendered "Compatible" are specified by the Airport Land Use Plan and are the following: a. The Airport Land Use Commission must examine the proposed use prior to approval, andb. The Airyort Land Use Commission must determine appropriate conditions for development which will render the "Conditionally Approvable" use "Compatible". Criteria which must be considered by the Airport Land Use Commission in determining appropriate conditions with regard to "Conditionally Approvable" land uses include, but are not limited to: KENNEDY STAFF REPORT - JLTNE 20,2OOI Attachment 7 Page 3 a. The location of the proposed use in relation to the airport (answer: The subject site is approximately 6500 feet northwest of the end of Runway 29.b. The density of population generated by the proposed (snswpt: during peak hours approximately 120- 200 will utilize the proposed businesses)c. The noise zone in which the use is situated (arywet: the entire property is located within the 55-dB CNEL airport noise contour, however the proposed retail stores are not noise sensitive uses)d. The location in relationship to flight paths.(answer: not determined) RECOMMENDATION Staff recommends that the Airport Land Use Commission determine that the proposed project be consistent with the San Luis Obispo County Airport Land Use Plan because it is designated as a " Conditionally Compatible" use and can be made "Compatible" with conditions. The following requirements are imposed as conditions of any building or use permit: 1. Sound proofing to reduce noise to acceptable levels per City of San Luis Obispo requirements2. Nonreflective materials to be used on buildings and signs.3. The allowed uses can be established in this Special Industrial District portion of the Commerce Park Specific Plan and shall be limited to the following: advertising, public relations, agricultural uses including cultivation of field, vine or tree crops, pasture or grazing and other outdoor agricultural activities, broadcast studios, computer services, credit reporting andcollection, delivery, mailing, and postal services, detective and security services, electronic, optical, pharmaceutical and other precision products, parts, instruments or equipment, or similar manufacturing Iaboratories, otlter technical facilities for research, testing and processing, medical, and analytical, ffices (architects, engineers, industrial design), printing and publishingfirms, accessory ffices,machine shops, cafeterias, recreation rooms and similar incidental uses or supportfacilities serving the employees of allowed uses, public utility, construction engineering, soils testing and similar design, health clubs an d r e cre at io n al fa c ilit ie s.

This offer was made so as to present the Regional Board's view on what field activities could be conducted at the earliest initiation of field work; the ranking was not intended to indicate the Regional Board believed selected characterization efforts were superfluous. However, upon review of Version 2.0 of the Data Gaps Report, ratified on July 26,2000, a ranking of characterization work that should be conducted before any other does not appear necessary. Rather, our recommendations are as follows: 1. Recommendations included in the Data Gaps Report are not exceedingly extensive. Therefore, characterization to address NAPL occurrence, properties and actual composition should occur as soon as possible within the 2000 field season. Because field equipment will be mobilized for the characterization activities, data to address possible future remediation methods should also be collected during the same mobilization effort. 2. As noted in Recommendation 8 (pages 1l and 12) and as briefly discussed during the August 4,2000 conference call, RTP participants - - particularly Unocal - - should give further consideration to scoping one or more "remediation pilot studies" to address near-surface NAPL migration in the near term. After presentation and discussion of data collected during the trenching portion of the site- wide hydrology study, this issue should be revisited at the September 2000 RTP meeting. 3. Data collected during July 2000 trenching activities should be reported so as to address Recommendation 54 (page 8) and any additional recommendations suggested by the RTP at the July 26,2000 site visit. This reporting is not expected to conflict with Unocal's desire to keep trenching issues associated with the hydrology study rather than with characterization recommended in the Data Gaps Report. As a final point, we acknowledge that implementation of the Data Gap Report's recommendations are essential to understanding contamination issues at the San Luis Obispo Tank Farm and we appreciate Unocal's and the RTP's ongoing participation in this cooperative effort. However, because of our charge Caffirnia Environmental Protection Agency {6 Recycled Paper Mr. Ken Smith August 14,2000 of protecting water quality and our role in future uses of the San Luis Obispo Tank Farm property, we may identiff still more issues that warrant attention as our data evaluation continues.

Please refer to the following comments: 1. Emergency vehicle access and circulation should be constructed to accommodate City fire apparatus. Minimum unobstructed roadways shall be 20 feet in width' 2. Fire flow for the project shall be supplied with a connection to the City water system that is capable of delivering fire flows in accordance with Appendix III-A of the califomia Fire Code. 3. Fire hydrants sha1l be installed in accordance with Appendix III-B of the Califomia Fire code. Hydrants specifications should meet exiting city engineering standards' 4. All buildings, including apartments, townhouses and single-familY residences should be protected witir automat]c hre sprinklers in accordance with the appropriate National Fire protection Association standard. It is our position that sprinklers should be viewed as a necessary mitigation that supports a less ihan significant impact as it relates to fire protection services. 5.

It is bounded on the south by Higtrland Drive, the east by Highway 1, thenorthby existing multi-family residences, and the west by existing single-family residences. Project Objectives As part of a comprehensive update identified the need for additional U of the Cal Poly Master Plan from 1998 to 2001, Cal Poly niversity-provided housing for students, staff and faculty.Altemative locations for this housing were analyzed in many studies, including the GordonH. Chong & Partners and Sedway Group Housing Study(1998), the Student HousingProject EIR (1999), and the Master Plan EIR (2001). Theproposed site was not considered suitable for sfudent housing because of its distancefrom the campus instructionalcore, adjacency to residential neighborhoods and small size; however, a small developmentfor housing faculty and staffhas been found to be moremarketabie and compatiblewith surrounding neighborhoods (Chong 1998). Figuro 2 - Prcjst Localion Cat Poly has difficulty atkacting and retaining facultyand staff due to the region's high cost of living and housingprices. To address thisdifficulty, the project is proposed with the following objectives: 1 Provide quality rental housing at attainable prices to athact and retain faculty/staff andtheir families. Work with the city on a cooperative basis to provide this new howing for faculty and staff. Deliver the faculty and staff housing consistent with the campus' master plan. Minimize parking and traffic impacts on the campus and neighborhood. Mnimize the effects of the proposed housing on surrounding land uses, including traffic, noise, and other visual/aesthetic impacts. 2. J. 4. 5.

AesthetiGsr Light and Glare lssues The project site is located at a primary gateway to the City of San Luis Obispo and in close proximity to Highway 1, a scenic highway. Development of the project will alter views in the immediate area. Background The analysis of visual impacts is not an exact science. There have been few comprehensive progtams designed to incorporate visualization tools into modeling systems, or evaluate the usefulness and applicability of such systems. Quantitatiae analysis is therefore difficult at best' As a result, visual quality is often rated on a relative qualitatiae scale, which places high value on expansive, prominent features, variation in topography and items of visual interest such as rock outcroppings or peaks. Analysis for this particular site is further complicated in that existing models (U.S. Forest Service, Federal Highway Administration) generally measure the change in a site's visual quality from major roadways. The majority of this site is not visible from Highway L, a scenic highway; the potential impact therefore lies not in alteration of the visual quality of the site itself as viewed from Highway 1. but in obstruction of views of distant peaks. Furthermore, existing models focus on the analysis of scenic resources visible to a large number of people from major roadways or specific scenic vistas, not private views. The following analysis is therefore based largely upon the degree of obstruction of the distant Morros from Highway L. The degree of obstruction is determined using computer simulations of the proposed housing, based on current co . *ere--is-*e eeneefittrd drawing fer tlre Freposed preieet te date; €al Pel]- has aEreed trpeft a btril€ling ^nvelepe, hervever, arC tlrat the Freieet rvill ineltrde apartmentstyle bcildfurgs in a eetrrflard anal1"siis-, Views from private residences are assessed using a truncated version of the U.S. Forest Service Visual Assessment System. Details regarding the methodology of this system are outlined in the following paragraphs, largely excerpted from the San Luis Obispo Area Plan EIR (rees). Scenic Variety Scenic variety is evaluated based on relative variations in nafural characteristics such as landscape character, landforms, vegetation, drainage, and urban components, if applicable. Table 5.1.1 describes the scenic variety/visual character dasses for the natural landscape elements and urban design character and rates them as distinctive, corrunon or minimal. The rating for the natural landscape elements is based on the U.S. Forest Service Visual Management System, while the rating for urban design character has been adapted to this system, based upon urban design criteria presented in Fundamentals of Urban Design by Hedman and ]aszewski.

Design linkagesabsent, otstrong unitywith no design variation (monotonous). Visual Sensitivi$ The visual sensitivity of a site is based upon the viewer's sensitivity level. Factors that affect visual sensitivity reflect the viewer's awareness of the scenic resources of the site, including the levels of public concern, and frequency and level of detail from which the resource is viewed. Table 5.L.2 provides the criteria for sensitivity levels from 1 to 3 with a rating of 1 being the most sensitive with assumed frequent viewing by a higtrly concerrred public. In accordance with the criteria developed by the U.S. Forest Service, great concern over visual quality is assumed to be felt by those driving for pleasure or those engaged in recreational activities. Conversely, less concern is assumed for those driving to and from or during work. Enaironmental lmpact Report 72 CnI Poly Faculty/Staff Housing Proiect - Site H-8 Table 5.1.2.

VisualConditionA determination of the overall visual attractiveness of a region is defined as the visual condition. The determination is based on the inherent characteristic variety of the resources and the degree to which introduced features appear uncharacteristic or incongruous with their surroundin;s, thereby disrupting the continuity of the scene. Table 5.1.3 provides a descriPtion of the visuJ condition classes, riting them VC-1 through VC-5. A rating of VC-1 indicates that all the features within the field of view appear characteristic of the regiort while a rating of VC- 5 indicates that the underlying characterof the area is uruecognizable within the viewer's field of vision.

This is consistent with mitigation measures contained in the Master Plan EIR (2001) that call for minimization of light and glare for any project. Setting The Site As Viewed from the Nearby Residences and Highland Drive. The site is currently undeveloped. The site slopes downward from Highway 1. at its western edge towards existing single-family residences to the east. Existing features on site consist of ruderal grassland vegetatiory a small drainage swale, areas of needlegrass vegetatiory and eucalypfus trees. There are no manufacfured structures on the site. The existing visual quality of the site and the immediate surroundings (as viewed from nearby neighborhoods) as defined by the aforementioned criteria is outlined in the following table. Based on the above criteria, the existing visual quality of the site is generally moderate to low. The site lacks distinguishi^g features. It is not generally visible from Highw ay 1, a major touristand recreational corridor, reducing the viewer sensitivity. It is not in an area of distinctiveurban design. The overall visual condition as viewed from the residences is diminished because of the domination of the Highway in the background.

Visual Condition Class VC-2 Uncharacteristic features (residential homes) compete for the view but are largely subordinate and subdued. The overall quality of the view from the roadway is considered high. This conclusion is consistent with City and County ratings of the Highway 1 corridor in this area. The Surrounding Neighborhoods The character of existing development in the vicinity of the proiect site is relatively consistent.I fo tne south and north there is two-and+hree-story multi-fannily housing typicailybccupied bystudents. The multi-family housing is varied in style with some complexes that are barracks-like and some that appear to be more townhouse-style. The areas around the buildings are sParsely landscaped and contain mostly parking and access areas. Views from Highway L of these aparhnents consist mostly of flat walls, with windows and exterior balconies on someunits. The development style changes to the west of the project site; existing development inthis area consists mainly of single-family residential units at a relatively moderate density. The homes are one and two story with small backyards. Light Light in the project area is limited to light standards at the intersection of Highway 1 andHigtrland Drive and along Highland Drive to the south, as well as lighting associated withsingle-family and multi-family residences. Other major sources of light include the Cal Poly Sports Complex. Light from the complex is subdued at the project site because of interveningtopography. Existing light levels are considered typical for the urban area. Regulatory Setting The aesthetic character and architectural design of the Cal Poly campus is generally under thejurisdiction of the Cal Poly administration as delegated by the Board of Trustees. Cal Poly Ena ir onmmt al Imp act Rep or t L6 Cal Poly FacultylStaffHousing Project - Site H-8 specified development of design guidelines as part of Master Plan implementation; this process ,hls not yet begun. Until that time, decisions regarding appropriate design and character rests I with the administration. Although the City of San Luis Obispo does not have jurisdiction over the design of development that occuts on the Cal Poly campus, the proposed project site lies adjacent to_the city boundary, the visually sensitive Highway L corridor and a primary gateway to the City. The 2001 Cal Poly Master Plan EIR includes mitigation that recommends consultation with the City regarding ttre design of the proposed project. The EIR also recommends sensitive siting of development to reduce impacts to the City gateway. Visual resources in the project area inctude Bishop Peak to the west and Cerro San Luis to the southwest. Portions of Highway Lfuof -the project site have been designated a scenic highway. @ +: Thresholds of Significance State CEQA Guidelines cite a finding of significant impact if a project will have "a substantial, demonstrable negative aesthetic effect." Further guidance is provided by Appendix G of the CEQA Guidelines that state that a project's impacts are significant if the project would: o Have a substantial adverse effect on a scenic vista .

Short-term impacts associated with construction activities would includegrading of the site and the storage of construction equipment and vehides that would alter the character of the project site. However, since the project site is not located in a visuallyprominent area (i.e., is not visible from Highway 1.), and the equipment would only be visiblefrom a limited number of residences, these impacts are considered adverse but not significant (Class trI). Light and Glate. The project will introduce additional sources of light and glare from parkinglot lighting and residential exterior lighting to an area with relatively low existing light levels. These new sources of light will be visible to neighboring residences. Glare is produced when sunlight is reflected from surface materials of buildings and otherstrucfures associated with a developed site. Examples of sources of glare include asphaltparking lots, glazed surfaces (windows) and metallic roofing materials. Large expanses of flatbuilding surfaces with lighter building colors would also produce glare. Specific mitigation forthe reduction of glare from the Master Plan EIR (2001) is incorporated into the projectdescription to reduce impacts from glare to a less than significant level (Ctass III). Themitigation calls for the minimization of use of reflective materials in building constructioryincluding large expanses of west-facing glass and metallic roofs. The project will also involve parking lots and parking lot lighting. Mtigation included in theproject description that calls for the minimization and hooding of all light sources in the projectwould reduce impacts to a less than significant level (Class ltr). Views from Neighboring Residences. The Faculty/Staff Housing on Site H-8 will be visiblefrom the adjacent neighborhoods to the west and south. The introduction of buildings, parkingand other structures into an otherwise undeveloped setting will alter the visual character of the site. actsto views from the residences are not considered a substantial degradation of visual quality because the existing visual quality of the site is moderate to low. The project will not blockviews of significant scenic resources (i.e., the Morros) from the residences. Scenic Roadways (Highway 1).

CaI PoIy Faculty/Staff Housing Project - Site H-8 The City Guidelines contain specific provisions for the protection of visual resources. Examples of these provisions are listed below: 1,4.1 Views of important scenic resources from major streets should be preserved and improved to the maximum extent feasible. 1,4.3 Development along scenic roadways should not block views or detract from the quality of views. A. Projects in the viewshed of a scenic roadway should be considered as "sensitive" and require architecfural review. B. Development project should not wall off scenic roadways and block views. C. As part of the city's environmental review process, blocking of views along scenic roadways should be considerqd a significant environmental impact. D. Signs along scenic roadways should not clutter vistas or views. E. Street lights should be low scale and focus light at intersecdons where it is mostneeded. Tall light standards should be avoided. Street lighting should be integrated with other street fumifure at locations where views are least disturbed. However, safety priorities should remain superior to scenic concerns.

Efsting intersections configrrratio* upp"ur to be inefficient; edsting difficulties with area intersections will be exacerbated by occupancy of the project. SettingA traffi-c study was prepared for the project in May 2001. The following is a summary of the analysis contiined i" tt at report. The entire traffic study is included in this document as Applndix E. The reader shoutd note that the study assumed a maximum unit number of 84 a*lUitgs. The expressed maximum in this EIR is 85; the addition of one unit will not add significantly to the trip generation for the project, therefore the results of the traffic study are used. The project will be directly accessed from Highland Drive. Primary access to Higtrland Drivg will te provided via Highway 1. Secondary access will be provided via Ferrini Road and chorro Street. Key roads serving the project site are described below. State Route 1 (Highway L) is a four-lane north-south highway providing regional access to the site. It connects Morro Bay with San Luis Obispo and Highway 101' Highland Drive extends from the Cat Poly campus east of Highway 1 to the west apfroximately one mile from Highway L. It is a two-lane collector street west of Highway 1'*i u four-lane arterial east of Highway 1. It provides access to Cal Poly from Highway L and provides access to residential areas located north of Foothill Boulevard and east of Highway 1' It is two-lanes wide across the project frontage. Ferrini Road and Chorro Street are two lane streets. Ferrini Road is a local street that extends from Foothill Boulevard to Higtrland Drive. It provides access to residential development and a school located south of FeltonWay. Chorro Street is a neighborhood arterial that extends from Ferrini Road immediately south of Highland Drive through the downtown area of San Luis Obispo. Roadways are generally assigned levels of service, which comPare traffic volumes to the capacity of the ioadway. In urban areas, intersection delay is the most accurate measure of level of service. The following intersections were included in the study: The Highway UHighland Drive intersection is currently signalized. Highway 1 includes two througi lanes, a lefitum lane and a right tum lane on each approach. The eastbound Highland drive-approach, which serves traffic entering Cal Poly, includes an optional through/left turn Ena ir onm m t al lmp ac t ReP or t 25 Cal PoIy FacultylStaf Housing Proiect - Site H-8 lane and an optional through/right turn lane. The westbound Highland Drive approachincludes a left furn lane, an optional left-through lane and a right tum lane. A crosswalk is currently only provided across the south leg of Highway 1. The signal has six-phase operationincluding left tum phases on Highway 1. and separate eastbound and westbound phasing on Higtrland Drive. The Highland Drive/Ferrini Road intersection is located approximately 30 meters west ofHighway 1.. It is controlled by a stop sign on the northbound Ferrini Road approach. Ferrini Road has separate left and right turn lanes on its northbound approach. A single lane isprovided on the eastbound and westbound Higtrland Drive approaches at this intersection. Traffic operations are complicated by an existing bus stop located on the north side of HighlandDrive immediately across from Ferrini Road. A second complicating factor is the vertical alignment of Highland drive immediately west of this intersection. Highland Drive has a very steep downhill gradient and a sharp crest vertical curve that limits sight distance to approximately 30 meters (100 feet). Traffic on HigNand Drive between Highway 1 and Ferrini Road regularly utilizes the entire storage distance between Highway L and Ferrini Road. Westbound Highland Drive left tums onto southbound Ferrini Road currently total about 60 during the moming peak hour and 182 during the evening peak hour. There is no left turn channelization provided for this movement. The limited sight distance reduces the capacity and safety of this left turn movement because it is difficult to observe approaching eastbound baffic on Highland Drive. This westbound turnmovement has a high level of discomfort because there is no refuge area protecting it from westbound through traffic approaching from the east. There is an existing "Limited Sight Distance" sign with a 15 mile per hour advisory speed plate on eastbound Higtrland Drive approximately 125 feet west of Ferrini Road. However, a speedsurvey conducted during the traffic study indicated that the 85ft percentile travel speed onHighland Drive at the base of the hill approximately 200 feet west of Ferrini Road was about 35miles per hour in the westbound direction and about 32 miles per hour in the eastbound direction. The signage therefore appears to be only margirnlly effective. The Ferrini Road/Chorro Street intersection with Highland Drive is a "T" intersection located approximately 30 meters (100 feet) south of the Highland Drive intersection with Highway 1. It is controlled by a westbound stop sign on Chorro Street and a northbound stop sign on Ferrini Road. Southbound Ferrini Road traffic departing from the Highland Drive intersection is givenright of way priority. The intersection of southbound Ferrini Road with Chorro Street forms a"Y," with the stem represented by the north leg of Ferrini Road and the two arms represented by Chorro Street and the south leg of Ferrini Road. Impacts to street systems are assessed using levels of service, or LOS. LOS is a measure of thecapacity of a roadway versus the number of cars utilizing the roadwayt or the delay experienced at an intersection. LOS is calculated on a scale from A to R with A indicating free-flow conditions, and F indicating gridlock. The number of cars on a roadway is measured by average daily traffic, or ADT. ADT is measured by counting the number of cars passing a certain point. Existing lntersection Levels of Service Existing peak hour traffic volumes for study intersectiors were collected on Tuesday andThursdap February 6 and 8,200'1, fromT to 9 am and 4 to 6 pm.

Highland Drive has been studied under the City of San Luis Obispo's Neighborhood Traffic Management Guidelines in response to community concemsover traffic speeds and amounts (January 2000). The Neighborhood Traffic Management Guidelines place a maximum of 3,000 vehicles per day on the Highland Drive Corridor. Vehicle amounts as presented in the City's study are outlined in the following table. Table 5.6.3: Traffic Volumes: City Neighborhood Study Seernent Eastbound Westbound Total Ferrini to Cuesta 1,900 1.,724 3,624 Cuesta to leffery 't,41,3 1At9 2,832 Tefferv to Patricia 71.5 724 1,439 CorridorAverage 1343 1,289 2,632 Note that the segment between Ferrini and Cuesta exceeds the recommendation, while the others do not, and that the average vehicle amount is not in excess of the guidelines. The project is expected to generate 492 ADT. It was estimated that 50% of the project tripswould be from Higtrland Drive east, 10% from Highland Drive west, 107o from Highway 1 southbound, 57o from Highway 1 northbound,l0"/" from Chorro Street, and 5% from Ferrini Road south. A reasonable worst-case approach to the Corridor Study would be to add all the project trips to Highland between Ferrini and Cuesta, and then recompute the average. The corridor average would increase to2,828 vehicles, still below the recommended level.2 2 Note that if every vehicle trip traveled the entire route of Highland Drive west to Patricia, the corridor averagewould increase lo 3,124, slightly above the City recommendation. Of course, this is not a reasonable scenario.

Enoironmantal Impact Report gZ Cal Poly Faculty/Staff Housing Project - Site H-8 7. Alternatives Section 15126 of the CEQA Guidelines requires that an EIR consider a range of reasonable alternatives or altemative locations to the prdposed project that are capable of avoiding or substantially reducing its associated significant effects. The range of altematives must be capable of ichieving the basic objectives of the project, and must be guided by the "rule of reason" which requires that an EIR analyze only those alternatives necessary to permit a reasoned choice. Description and Analysis of Alternatives No Proiect Alternative Under in" Uo Project Alternative, no development would occur. Since no development would occur, all impacts identified in the EIR analysis would be either minimized or eliminated. However, the no project altemative would not meet the basic objective of providing housing for faculty and staff. In addition, the no project alternative would mean that new faculty and staff would not find housing provided by Cal Poly, but would need to enter and exacerbate an already constrained housing market. Thus, the no-project alternative would have an adverse impact on housing in San Luis Obispo' Master Plan Enrollment Alternatives The location of the two faculty and staff housing sites was the result of a three year planning process which began with a constraints analysis and the development of policies in conjunction with municipal officials and citizens. As stated earlier, this EIR is tiered from the Master Plan EIR (SCH 2000101072) that resulted from this process. It also incorporates by reference the analysis of housing impacts and site alternatives included in Cal Poly's EIR for the Student Housing Project (SCH 99031006). The California State University Board of Trustees approved the Master Plan update and its Environmental Impact Report in March 2001. Because of the increasing demand for higher education in California, the California State University system leadership asked Cal Poly to explore how it could increase its enrollment capacity. To accomplish this directive, cal Poly revised its Master Plan. The Master Plan process examined a range of altemative enrollment configurations that would allow Cal Poly to graduate an increased number of students without additional facilities on campus. These included: o Increased summer enrollment to take advantage of the current facilities on a year round basis;o Increased student progress, refining administrative procedures and curricular requirements to reduce the time a student takes to graduate; ando Distributed teaching and leaming, which increases the use of off-campus facilities and the use of enhanced technology (especially the internet). The Master Plan adopted an approach to growth that incorporated all of these measures plus additional growth during the academic year because the first three altematives are not sufficient to meet enrollment demand. Thus, the Master Plan provides for additional Enoironmmtal Impact Report 33 Cal Poly FacultylStaff Housing Project - Site H-8 instructional facilities to serve this additional enrollment, and estimates a need for an additional 465 faculty and staff to serve the additional students. During this same period, Cal Poly will experience a large number of retirements - requiring the recruitment of about 55 faculty and staff annually to replace those leaving Cal Poly. This number is significantly larger than the number of recruitments to serve new enrollment. Faculty and some administrative staff are recruited from outside the Central Coast. Therefore, none of the alternative enrollment scenarios, including no enrollment growth, would eliminate or significantly reduce the demand for faculty and staff housing. Master Plan Alternative Sites Consistent with the Cal Poly missiory with its emphasis on undergraduate education in polytechnic fields and applied learning both in and outside the classroom, Cal Poly determined that it should provide more students with the opportunity to live on campus. Further, because of a critical shortage of housing in the nearby community, Cal Poly made it a policy to increase the proportion of students living on carnpus significantly - at a minimum to provide enough housing for all new enrollment proposed in the ldaster Plan. "Further, Cal Poly will monitor the local market closely, and, if continuing students are not able to find suitable housing, the campus will develop a strategy to house a larger proportion of the University's students in thefuture" (Cal Poly Master Plan, 2001, p. 136). The ability of the campus to provide housing became a limiting factor in determining an appropriate level.of enrollment growth. The search for housing sites was an important component in the development of the Master Plan. A section of the Master Plan was dedicated to housing, documenting the policies developed over the course of several dozen meetings with community members and govemment officials.A constraints analysis was prepared for Cal Poly's 6,000-acre land holdings in San Luis Obispo County to determine areas appropriate and inappropriate for development. Consideration wasgiven to natural resources, campus resources (such as existing facilities) and nearby neighborhoods. The Master Plan process and team examined numerous locations for housing.In additiory the plan contained policies that guided the location of housing. The land use and residential communities elements show the current location of the H-8 housing site, identifying the location as appropriate for faculty and staff housing. It is important to underscore how the Master Plan process developed campus land use designations balancing three factors to achieve the most appropriate spatial organization ofuses: the amount of land required for each use, the physical suitability of land for any particular use, and the most appropriate location for each use. Within the area physically or environmentally suitable for development, the Master Plan had to designate sufficient land areafor instructional facilities, support functions (such as parking and recreation), and housing. Thus, the Master Plan process integrated the identification of sites for faculty and staff housing and student housing with the selection of sites for instructional and support facilities. The goal was to find the most suitable location for each use, in relation to other campus land uses. The Master Plan analysis identified land to be unsuitable for housing for one or more of several categories: Areas not suitable for any development, primarily for environmental reasons or due to locatiory such as the following: Enuironmantal lmpact Report g4 Cal Poly Faculty/Staff Housing Project - Site H-8 . Steep slopes or other geologic hazatds;. Environmentally sensitive areas, including riparian areas and biological Preserves;. Soils designated as Class I according to the Natural Resources Conservation Service classification system, which are considered most productive for agriculture;o Remote land, too far from roads or utilities to make development practical. Areas required for instructionally related activities that support the Cal Poly polytechnic mission:o Expansion of the campus instructional core to meet future enrollment needs and related support activities;. Agricultural laboratories; principally land in row croPs, orchards and the like;o Other outdoor instructional fields and facilities; Land considered suitable for housing had the following characteristics: o Proximity to the campus instructional core to reduce the need for commuting and to take advantage of on-campus activities (primarily for student housing);. Proximity to edting roadways and infrastructure;r Proximity to the City of San Luis Obispo. Most of the land that fit these characteristics was located in a belt on the eastern edge of the campus instructional core, near existing student residences. In order to increase the proportion of students living on carnpus, as stated above, Cal Poly designated all of this land for future student housing. Lr contrast, Sites H-8 and H-9 were considered particularly appropriate for faculty and stafi housing, but inappropriate for student housing, given their distance from the .u*p.tr instructional core, and the proximity to existing residential neighborhoods. Conclusion: Because the Master Plan involved a comprehensive analysis leading to the designation of areas suitable for development, relocation of any particular use would require re- exariination of other land use designatiors as well. Relocation of faculty and staff housing from H-8 to an altemative location deemed suitable for housing in the Master Plan would require relocation of sfudent housing. However, such a shift would result in the location of boih faculty and staff housing and student housing on sites that would be less suitable than under the Master Plan. Impacts are corsidered more significant under this altemative' Figure 10 displays the results of the Master Plan analysis in summary form. The reader is ericou.aged to refer to the Master Plan EIR for further discussion of the constraints associated with the provision of student housing on carnPus' Relocation to Ranch Land This alternative proposes relocation of the project to Cal Poly's ranches i"-fu San Luis Obispo and Chorro Creek iatersheds. These include Cheda Ranch in the northwest corner of Cal poly's acreage near San Luis Obispo, and the Chorro Creek, Walters and Escuela ranches west of Cuesta Community College. The ranches are not prograrnmed for residential development in the Master plan followit g ttr" analysis discussed above. Environmental impacts associated with this alternative are analyzed below.

The introduction of attached or detached residential development in any of these areas would be inconsistent with County and University goals for rural areas of the County, which generally call for preservation of open space and agriculfural character, and would have a gteater impact than the proposed project, which consists of infill adjacent to a largely developed area. This altemative would also introduce light into an unlit area. This impact is considered more significant than the proposed project. Agriculture: All of Cal Poly's ranches are used by the College of Agriculture a! Cal Poly. Only small portions of the ranches are considered prime agricultural soils, therefore the housing could conceivably be sited on non-prime soils similar to the proposed project' Impacts are considered similar to the proposed project' Biological Resources: Cal Poly's ranches support grassland habitats similar to the proposed projeit. The ranches are part of a more contiguous network of open sPace, however, and may provide more habitat value for foraging and migrating wildlife. Botanical snrveys of portions of tne ranches (included as an appendix to the 2001 Cal Poly Master Plan EIR) revealed similar compositions of plant species. Wetlands located on the ranches could conceivably be avoided. Impacts are likely to be similar to or greater than the proposed project depending on location. cMc CAMPsLo Enaironmental lmp act Rep ort 37 Cal Poly Faculty/S taffHousing Project - Site H-8 Cultural Resources: A records search completed for the Master Plan revealed a relatively high density of culfural resotirces on the campus ranches. This alternative could therefore result in similar or greater impacts to cultural resources than the proposed project, depending on location. Geology and Soils: The site-specific characteristics of ranch soils are not well understood. Impacts would likely be similar to the proposed project, depending on location. Hazards and Hazardous Mnterinls: Generally, hazardous materials are not expected to occur on the ranches. Some locations on the Chorro Creek ranches may have unexploded ordinance from exercises at Cu*p San Luis Obispo. Serpentine soils present on some of the ranches may also pose hazards associated with asbestos exposure. Impacts are similar to or greater than the proposed project, depending on location. Land Use and Planning: Location of attached or detached housing on any of the campus ranches would be inconsistent with Master Plan policies which call for compact development and attempt to contain sprawl, and City and County policies which aim for the preservation of agricultural and open space character in the area. lmpacts would be greater than the proposed project. Mineral Resources: No mineral resources are expected to occur on any ranch site. Impacts are similar to the proposed project. Noisc Short-term construction noise would be less noticeable at the ranches because of the lack of neighboring residences. Long-term noise would be similar to the proposed project, but may be more significant becalrse of the absence of existing ambient noise in the area. Public Sercices: Provision of water and sewer would involve the extension of infrastrucfure to a previously unsenred area. The altemative is likely to have a greater impact than the proposed project because of the need to extend such services. Recrmtion: Impacts would be similar to the proposed project. Transportation and Circulation: Traffic levels are not expected to be greater than the proposed project, although the distribution would be different, with most traffic entering Highway 1 further north. Impacts are considered similar to that of the proposed project however, because the altemative would require ingress/egress associated with Highway 1. Any location that could take advantage of an existing access point would in general be better, especially at a signalized turn or intersection. Conclusion: Impacts are generally considered more significant under this altemative, although they would certainly vary from site to site. This altemative is considered less acceptable because of the difficulty of providing services and access to this area, and the inconsistency of this location with area planrring documents.
