The 332-acre property was a former tank farm owned and operated by Union Oil until it was decommissioned in the 1990s. In 2005, the Chevron Environmental Management Company (CEMC) purchased the property and began preparing plans for site remediation and development. On September 2, 2014, the City of San Luis Obispo (City), serving as the lead agency under the California Environmental Quality Act of 1970 (CEQA), certified the Final Environmental Impact Report (FEIR) prepared by Marine Research Specialists (MRS) for the Chevron Tank Farm Remediation and Development Project SCH #2009031001). The County of San Luis Obispo (County), acting as a co-lead agency, approved the Conditional Use Permit (CUP) DRC2013-00056 on October 23, 2014, authorizing the CEMC to move forward with the site remediation and restoration component of the project. The site remediation and restoration addresses soil and groundwater contamination by excavating the top soil and sub- surface material to remove Non-Hazardous Impacted Soils (NHIS) affecting the project site. The FEIR evaluated the removal of NHIS and the haul routes used between the project site and the waste disposal facility. The grading plans prepared for the FEIR estimated that up to 196,250 cubic yards of NHIS would be transported from the project site to the Santa Maria Regional Landfill (SMRL), resulting in approximately 13,125 truck trips (round trips). At the time of the FEIR, the SMRL was the closest NHIS approved facility located approximately 31 miles south of the project site in Santa Barbara County. In 2016, the Cold Canyon Landfill was approved by the Regional Water Quality Control Board RWQCB) to receive NHIS. The Cold Canyon Landfill is located approximately 6.5 miles south of the project site in San Luis Obispo County. Based on the current and estimated remaining volumes of exported NHIS, the project would result in the total removal of approximately 277,250 cubic yards of NHIS, approximately 81,000 cubic yards more than what was previously evaluated in the FEIR. CEMC is requesting authorization from the County to allow for the additional NHIS to be exported offsite and to modify the existing approved haul routes to allow for NHIS disposal at the Cold Canyon Landfill. 202006_SLOTF_ProjectDescription_REV_RPT.docx 2-1 2.0 PROJECT MODIFICATIONS 2.1 ADDITIONAL NHIS EXPORT From 2017 to 2019, approximately 162,621 cubic yards of NHIS were removed from Operable Units 3 and 4, which primarily included the North Marsh Area, as well as Reservoir 2 and 4. It is anticipated that NHIS removal will continue until 2023, resulting in an estimated 114,629 cubic yards of remaining NHIS, totaling 277,250 cubic yards. Remaining areas with NHIS include Reservoir 5 and 7 within Operable Unit 2, and Reservoir 3 and the pliable petroleum surface hydrocarbon (PPSH) areas 1-8 within Operable Unit 4 (see Figure 1). Table 1 provides a summary of the current and estimated volumes of NHIS. The grading plans prepared for the FEIR estimated that up to 157,000 cubic yards of NHIS could be generated during site remediation activities. A 25% contingency was included in the offsite hauling numbers to account for uncertainties associated with estimating impacted soil volumes, increasing the volume estimate to 196,250 cubic yards. Since site remediation began, the extent of NHIS impacted areas were determined to be greater than what was previously estimated. Based on the current and estimated remaining volumes of NHIS export, the project would remove an additional 81,000 cubic yards for a total of 277,250 cubic yards. Table 2 shows the difference of the original NHIS estimates evaluated in the FEIR compared with what has currently been removed and the estimated remaining volume. 2.2 PROPOSED MODIFIED HAUL ROUTES At the time of the FEIR, the SMRL was the closest facility approved by the RWQCB and Chevron to receive NHIS. In 2016, the Cold Canyon Landfill was permitted by the RWQCB to expand its capacity and receive NHIS. Cold Canyon Landfill has also been recently approved by Chevron to receive NHIS. Cold Canyon Landfill is closer to the project site, and delivery to the facility would greatly reduce the total miles traveled for NHIS export. In addition, the SMRL is currently in the process of closing its NHIS program and is expected to stop receiving waste by 2025. Due to the proximity and recent availability of the Cold Canyon Landfill, and in preparation of the SMRL closure, CEMC proposes to modify the existing haul routes to include Cold Canyon Landfill as an additional NHIS disposal facility. The FEIR analyzed the following truck route: Westbound on Tank Farm Road Southbound on South Higuera Street 2-2 202006_SLOTF_ProjectDescription_REV_RPT.docx Either westbound on Los Osos Valley Road to the U.S. Highway 101 on-ramps or continue south to the South Higuera U.S. Highway 101 on-ramps Southbound U.S. Highway 101, trucks would exit at Betteravia Road in Santa Maria, travel east on Betteravia Road to Philbric Road, then north on Philbric Road to the City of Santa Maria Landfill entrance Northbound return trips would be the same route in reverse An alternative southbound route was also evaluated and consisted of the following: East on Tank Farm Road Southbound on Highway 227 Westbound on Price Canyon Road South on Price Street to the southbound U.S. Highway 101 on-ramp. The route from U.S. Highway 101 to the City of Santa Maria Landfill would be same The proposed modified haul route to the Cold Canyon Landfill from the project site consists of the following: East on Tank Farm Road Southbound on Highway 227 Continue on Highway 227/Carpenter Canyon Road (past Price Canyon Road for approximately 1.25 miles) to Cold Canyon Landfill entrance Trucks are permitted to enter the facility from southbound Highway 227/Carpenter Road by taking a left turn from the approximately 300-foot-long turn bay Proposed northbound return trip: North on Highway 227 West on Price Canyon Road North on Bello Street to northbound U.S. Highway 101 on-ramp Exit north onto South Higuera Street 202006_SLOTF_ProjectDescription_REV_RPT.docx 2-3 East Tank Farm Road Proposed alternative northbound return trip: North on Highway 227 West on Buckley Road North on Vachell Lane Northeast on Higuera Street East on Tank Farm Road Figure 2 shows the existing truck routes between the project site and US 101 and Figure 3 shows the proposed modified routes between the project site and Cold Canyon Landfill. The Cold Canyon Landfill is located approximately 6.5 miles from the project site via Highway 227/Carpenter Road. The facility is open to the public Monday through Saturday from 8:00 am to 3:00 pm; however, the facility is allowed to receive waste from 7:00 am to 5:00 pm. The facility is permitted to receive up to 1,650 tons and 542 vehicles per day, with a daily average of 800 tons and 300 vehicles. CEMC estimates that 114,629 cubic yards (approximately 146,725 tons) of NHIS will still need to be exported offsite, which would result in an estimated 7,164 truck trips (round trip) over the next four years. CEMC proposes to transport up to 650 tons per day to the Cold Canyon Landfill, which would result in approximately 25-30 truck trips (round trip) per day, averaging 4 trucks per hour. Use of the Cold Canyon Landfill would reduce each roundtrip truck trip by an average of 40 miles, which would represent up to a 15% reduction in total miles traveled for NHIS disposal. It is anticipated that all future deliveries would occur in coordination with Cold Canyon Landfill to prevent truck queues and to ensure daily deliveries do not exceed the facilities permitted limits. 202006_SLOTF_ProjectDescription_REV_RPT.docx 3-1 3.0 CONSISTENCY WITH PREVIOUS APPROVALS Activities related to the removal and transport of NHIS were evaluated in the FEIR and are currently permitted by CUP DRC2013-00056 (Attachment A). Exhibit B of the CUP outlines conditions of approval and corresponding mitigation described in the FEIR. The project would continue to comply with all applicable mitigation measures regarding the transport and disposal of NHIS waste and would not result in any new or more severe impacts than what was previously evaluated in the FEIR. The proposed changes are not substantially different than what was conditionally approved, and the project would continue to be subject to the same conditions described in the CUP. Since the certification of the FEIR, additional resources areas have been incorporated into Appendix G of the CEQA Guidelines including energy and wildfire. While it is not anticipated that the project would result in new significant impacts related to these resource areas, subsequent environmental review may be warranted. Potential impacts associated with the proposed project modifications are primarily related to air quality, traffic and circulation, and public services and utilities. Air Quality Mitigation measures AQ-1a, AQ-1d, and AQ-1e in the FEIR and conditions 27, 30, and 31 in the CUP require the applicant to implement emission reduction measures and a Construction Activity Management Plan (CAMP) to reduce criteria pollutants to below the San Luis Obispo’s Air Pollution Control District’s (SLOAPCD) air emissions thresholds. The CAMP (Attachment B) prepared for the project recognized that the Cold Canyon Landfill may become a receiving facility for NHIS in the future, which would result in a reduction of air emissions. In coordination with the SLOAPCD and the County, CEMC has revised the air quality emissions calculations presented in Appendix F of the CAMP (see Attachment C). Traffic and Circulation Mitigation measure T-1 in the FEIR and condition 59 in the CUP require the applicant to prepare a construction management plan to address impacts to roadways in the project vicinity due to the potential obstruction of heavy vehicles creating an unsafe situation. The Traffic Management Plan (Attachment D) prepared for the project currently includes a facility description and haul route for the Cold Canyon Landfill. In coordination with the County Public Works Department, CEMC proposes to revise the Traffic Management Plan, as applicable, to be consistent with the proposed modified haul routes. Public Services and Utilities 3-2 202006_SLOTF_ProjectDescription_REV_RPT.docx Mitigation measure PS/U-4 in the FEIR and condition 76 in the CUP require the applicant to prepare a waste management plan to address impacts related to the generation of solid waste requiring disposal at landfills. The Waste Management Plan (Attachment E) prepared for the project identified Cold Canyon Landfill as a disposal facility available to receive NHIS. The Cold Canyon Landfill is an approved facility to receive NHIS waste and has a permitted capacity to receive approximately 1.1 million cubic yards of waste until 2040. In coordination with Cold Canyon Landfill and the County, CEMC proposes to revise the Waste Management Plan, as applicable, to allow for transport of NHIS to the Cold Canyon Landfill. 202006_SLOTF_ProjectDescription_REV_RPT.docx 4-1 4.0 SUMMARY The FEIR prepared for the project estimated that up to 196,250 cubic yards of NHIS would be exported from the project site. Based on the current and estimated remaining volumes of exported NHIS, the project would result in the total removal of approximately 277,250 cubic yards of NHIS, approximately 81,000 cubic yards more than what was previously evaluated in the FEIR. At the time of the FEIR, the SMRL was the closest facility that was available to receive NHIS; however, the Cold Canyon Landfill has since been approved to receive NHIS. The Cold Canyon Landfill is closer than the SMRL and use of the facility would represent a reduction in travel distance and associated air emissions. CEMC proposes to increase the volume of NHIS export and to modify the existing haul route to allow for delivery to the Cold Canyon Landfill. The proposed changes are consistent with what has been previously approved and would not result in any new or more severe impacts than what was previously evaluated in the FEIR.

1.0 INTRODUCTION This Construction Activity Management Plan (CAMP) has been prepared by Padre Associates, Inc. (Padre) on behalf of Chevron Environmental Management Company (Chevron), for the San Luis Obispo Tank Farm Remediation and Restoration Project (Project), and in accordance with the San Luis Obispo County Air Pollution Control District’s (SLOAPCD) California Environmental Quality Act (CEQA) Air Quality Handbook (2012). The San Luis Obispo Tank Farm property is located at 276 Tank Farm Road in San Luis Obispo, California (Project Site). The location of the Project Site is presented in Figure 1-1 - Site Vicinity Map and Figure 1-2, Location Map. Figure 1-3 presents the Project Schedule by Area of Concern. Figure 1-4 illustrates the proposed trucking routes. The purpose of the CAMP is to consolidate and specifically define the air-related measures that will be implemented for the Project and to ensure all requirements are implemented throughout Project-related construction activities. This version of the CAMP includes revisions addressing comments from the SLOAPCD, revised Project-specific information (i.e., fleet make- up, emissions level, and schedule) and refined Project emissions calculations corresponding to an updated Project construction schedule. The Project details are based on anticipated implementation and current best estimates to be refined for the purposes of determining emissions upon which the mitigation payments are based. Chevron plans to remediate areas within the Project Site through excavation, offsite transport and capping techniques, and restore the future open space portion of the Project Site approximately 250 acres). Section 1.4 provides additional details regarding these activities. The overall project also includes future development on portions of the Project Site. The development components of the Project have not been finalized and will be permitted separately in the future. 1.1 SITE DESCRIPTION The Project Site is located immediately south of the city of San Luis Obispo, San Luis Obispo County, California. The Project Site is divided into north and south sections by Tank Farm Road, and is bordered by light commercial and industrial development to the east and west; the San Luis Obispo County Regional Airport is to the east; agricultural and pastoral lands with scattered residences are to the south. New residential subdivisions have been constructed to the north of Prado Road, approximately 0.25-miles north of the Project Site. A mobile home park is located within close proximity of the Project Site to the east (see Figure 1-2). The existing buildings in the northwest part of the Project Site are used as Chevron’s local offices. The buildings will be demolished as part of the Project. 1.2 SITE BACKGROUND This Project Site is owned, and was originally operated, by Union Oil Company of California (Union Oil). Chevron purchased Union Oil, including the Project Site, in August 2005. The San Luis Obispo Tank Farm was constructed in 1910 to serve as the accumulation point for the petroleum pipeline from the San Joaquin Valley. In 1926 many of the tanks on the Project Site were destroyed in a fire caused by a lightning strike. The San Luis Obispo Tank Farm was re-built and operated until the 1970s. The Project Site was slowly withdrawn from operation during the later decades of the twentieth century, and by the late 1990s it was formally decommissioned. Chevron San Luis Obispo Tank Farm Remediation and Restoration Project Construction Activity Management Plan Project No. 1301-0306 1-2 - 1.3 CONDITIONAL USE PERMIT / CONDITIONS OF APPROVAL This CAMP has been prepared for the purpose of complying with the Conditions of Approval (Conditions) in the Conditional Use Permit (CUP) (DRC2013-00056) and the SLOAPCD CEQA Air Quality Handbook. As needed, information and/or requirements presented in the Final Environmental Impact Report (FEIR), certified by the City of San Luis Obispo (Marine Research Specialists, 2013) are relied upon to provide background information and details regarding impact analysis and proposed mitigation. Specifically, this CAMP has been prepared to address the CUP Conditions 27-40, 86-89, 113, 114, and 125. This CAMP also addresses soil stockpiling plan requirements contained in Condition 107. Refer to Appendix A for the complete text of the air quality-related CUP Conditions. 1.4 PROJECT OVERVIEW The planned Project Site remediation and restoration activities relevant to the SLOAPCD Authority to Construct/Permit to Operate (ATC/PTO), CAMP, and other associated plans include demolition, grading, offsite hauling, the capping of former crude oil storage reservoirs, and the excavation and onsite/offsite cover/reuse of total petroleum hydrocarbon (TPH) and arsenic- containing soils at the Project Site. The following activities will be completed as part of the proposed Project: Demolition of the existing buildings and the removal or decommissioning in-place of remnants of oil operations, remaining pipelines (water lines, drain lines, leach lines, Foamite lines, and crude oil/gasoline lines), concrete walls, removal of misc. onsite debris piles, etc.; Grading to remove or flatten various earthen berms including Reservoir 2, portions of berms next to Tank Farm Road, etc.; Removal of berms and topsoil to be used as backfill or in restoration areas; Placement of engineered fill to cover the Northwest Operations area and Reservoir 4; Construction of remediation caps at Reservoirs 3, 5, and 7; Excavation and offsite disposal of areas of pliable and plastic surface hydrocarbon expressions within the North Marsh and elsewhere at the Project Site; Excavation of arsenic-containing soils near the Northwest Operations Area and northeast of Reservoir 2 and placement of the material in the Northwest Operations Area under the remediation cap; and Grading and habitat restoration, monitoring and maintenance in the future open space. The previously proposed blasting and crushing activities at the former quarry area (Flower Mound) have been deleted from the proposed scope of activities covered under this CAMP. A more detailed discussion is provided below. 1.4.1 Demolition of Buildings and Former Oil Operations There are four buildings at the Project Site, located in the Northwest Operations Area, that will be demolished during the course of remediation activities. Three of these buildings were constructed to support historical operations at the Project Site. Two of these buildings have undergone asbestos and lead paint abatement and are no longer used, and the third is used Chevron San Luis Obispo Tank Farm Remediation and Restoration Project Construction Activity Management Plan Project No. 1301-0306 1-3 - primarily as office space. The fourth, a modular building installed adjacent to the northernmost original building, was constructed within the last 18 years to provide additional office space. Prior to demolition, recyclable or potentially reusable materials will be removed from the buildings. It is anticipated that the buildings will be demolished using excavators. Water spray will be utilized to control fugitive dust during the demolition procedures. Some of the buildings have metal structural elements or siding, which will be segregated for recycling as feasible. Waste and recyclable materials will be loaded into haul trucks for disposal. Concrete foundations will be broken apart using a hydraulic hammer, and hauled to an approved concrete recycler. 1.4.2 Pipeline Segment Removal The Project Site contains approximately 25,000 linear feet (LF) of crude oil pipeline, 47,000 LF of water supply line, and about 1,200 LF of miscellaneous pipelines. Chevron will either remove or decommission in-place the pipelines remaining at the Project Site, in accordance with the Project’s Pipeline Decommissioning Plan (Appendix B). Refer to Appendix B – Pipeline Decommissioning Plan, for the inventory of site-wide pipelines and procedures to be following during pipeline purging activities. All pipeline segments scheduled for removal that contain coatings or wrap will be inspected by a Certified Asbestos Consultant (CAC) or Certified Site Surveillance Technician (CSST) working under the auspices of a CAC for the presence of asbestos-containing materials. Chevron proposes to utilize the existing PTO NO. 735 (and the accompanying Pipeline Purging and Emission Reduction Plan) for onsite pipeline degassing and removal activities. 1.4.3 Grading and Soil Handling The estimated total grading volumes (excavation volumes, arsenic and TPH-containing affected soil, fill material, etc.) removal volumes, and excavation depths for each proposed restoration feature are presented in tabular format in Table 1-1.

For areas where the targeted contaminant is not visually apparent (such as arsenic), sampling may be conducted to verify that the remedial goals have been met. Excavated soil considered suitable for reuse as backfill will be segregated and stockpiled. It will be sampled prior to reuse to ensure that it meets the screening criteria as presented in Section 5. Two areas within the proposed open space portions of the Project Site were identified with shallow soil arsenic concentrations equaling or exceeding the Project Site-specific background inflection point of 6.9 milligrams per kilogram wet weight (mg/kg). The proposed remedial actions at these locations include the removal of the upper one to three feet of soils (an estimated total of 2675 cubic yards) and placement of the excavated soils within the proposed soil cap at the adjacent Northwest Operations Area. Following the completion of remedial excavation activities, the areas will be backfilled with clean soil and graded to match the surrounding surfaces. Petroleum hydrocarbon-containing soil will be removed from the Project Site to the Santa Maria Regional Landfill (SMRL) or another approved landfill facility, and clean soil will be either generated from an onsite source or imported to the Project Site for use in backfilling the excavations. The Project is planned to excavate affected soils above the groundwater. However, as required by CUP Condition 62, a Dewatering Contingency Plan (Padre, 2016a) has been prepared in the event that groundwater is encountered during excavation. The contingency plan provides for groundwater to be transferred to temporary closed-top storage tanks via either dewatering wells or sump pump(s) installed at the bottom of the excavation. The stored water will either be treated and disposed of onsite via a RWQCB authorization, or will be hauled and disposed of offsite, in accordance with the Project’s Dewatering Contingency Plan. Fugitive emissions control and monitoring will be conducted during water storage and treatment as discussed in Section 2.6 of the Air Quality Monitoring Plan (AQMP) included as Appendix C. 1.5 PROJECT SCHEDULE The Project construction schedule will be subject to change due to field conditions at the time of implementation (weather, habitat/species in work area, etc.) but is currently projected to require ten years to complete. A summary of the ten-year Project schedule for the primary remediation tasks is shown below. Figure 1-3 provides an illustration of the proposed construction schedule by Areas of Concern. Appendix F provides additional detail and the complete Project construction schedule providing the basis for the emission estimates.

Additional sensitive receptors are residents of the Hidden Hills Mobile Home Park, located at 650 Tank Farm Road east of the Project Site, residences along Prado Road, residences south of the Project Site, and surrounding businesses. Additionally, new housing is also being constructed to the north of the Project Site along Prado Road. Refer to Figure 1-5 – Sensitive Receptors Map for the locations of sensitive receptors in the vicinity of the Project Site. The proposed Project will minimize impacts to existing offsite receptors with implementation of all measures in this CAMP. The affected soil will be taken to an appropriately permitted landfill for beneficial reuse as Non-Hazardous Impacted Soils (NHIS). Currently, the Santa Maria Regional Landfill is the only nearby facility with an appropriately permitted NHIS program. The primary route for trucks transporting affected soil offsite to the Santa Maria Regional Landfill includes trucks traveling westbound on Tank Farm Road to South Higuera Street with trucking entering southbound U.S. Highway 101 at the South Higuera Street on-ramp. Returning trucks will utilize the same primary route. A secondary route has been identified for use if the primary route is unavailable. The secondary route includes trucks traveling eastbound on Tank Farm Road to Broad Street (State Chevron San Luis Obispo Tank Farm Remediation and Restoration Project Construction Activity Management Plan Project No. 1301-0306 1-15 - Route 227), then south on State Route 227 to Price Canyon Road, then westbound on Price Canyon Road to the U.S. Highway 101 southbound on-ramp at Price Street in Pismo Beach. Cold Canyon Landfill has recently received updated permits from the RWQCB that include provisions to accept NHIS. Chevron is working with Cold Canyon Landfill on necessary approvals to become a receiving facility for Chevron’s NHIS. If Cold Canyon Landfill becomes a Chevron- approved receiving facility, Chevron will process a modification to add it to the County CUP as a Project-designated NHIS disposal facility. Trucks going to the Cold Canyon Landfill would travel eastbound on Tank Farm Road to Broad Street (State Route 227), then south on State Route 227 to the Landfill; the route would be reversed for returning trucks. The distance for a trip to the Cold Canyon Landfill is 20 miles shorter than one to the Santa Maria Landfill, so emissions from hauling operations would be reduced from the calculations included in Appendix F. The air quality emissions calculations presented in Appendix F would be revised and submitted to SLOAPCD if Cold Canyon Landfill is added as a Project-designated disposal facility. The designated truck routes were selected to avoid sensitive receptors to the extent feasible. The designated truck route was included in the FEIR, certified by the City of San Luis Obispo in 2014. One private school is located within 1,000 feet of designated SMRL truck route – the Montessori Children’s School located at 4200 South Higuera Street. Los Ranchos School is located 100 feet from State Route 227 alternative southbound route. The designated truck route would not pass within 1,000 feet of any parks/playgrounds, hospitals, or nursing homes. 1.7 SUPPORTING DOCUMENTS The following supporting documents and plans have been prepared under separate cover: Final Environmental Impact Report (FEIR – Marine Research Specialists, 2013); San Luis Obispo County Conditional Use Permit (CUP) (DRC2013-00056); Remedial Action Plan (RAP) (Avocet, 2015); Remediation Construction Drawings, (Avocet, 2016); Dewatering Contingency Plan (DCP) (Padre, 2016a); and Traffic Management Plan (TMP) (Padre, 2016b). 1.8 PLAN ORGANIZATION This CAMP is organized as follows: Section 2 presents a summary of the air quality impact analysis; Section 3 provides an overview of the construction equipment emissions reduction measures; Section 4 presents an overview of the dust mitigation plan; Section 5 provides measures for soil segregation and stockpiling; Section 6 presents the complaint response procedures; and Section 7 provides a summary of recordkeeping and reporting requirements.

The primary sources of pollutant emissions for the Project would result from the use of internal combustion engines during construction activities and soil disturbance. Specifically, conventional construction equipment such as excavators, backhoes, loaders, compactors and trucks will be utilized during excavation and other activities. Additional sources of air pollutant emissions include emissions from on-road motor vehicles used to transport materials and personnel, and fugitive dust emissions from activities involving soil disturbances. Criteria pollutant emissions for heavy construction equipment during the remediation activities were estimated using established emission factors from the California Air Resources Board’s (CARB) CalEEMod model. Emissions associated with worker travel to and from the Project Site and haul-truck traffic were estimated using the CARB’s EMFAC 2014 model. A tabulation of assumptions, references, and calculations for the Project emission estimates are provided in Appendix F. Table 2-1 lists the maximum daily and quarterly estimated Project emissions presented in the FEIR (MRS, 2013). Revised maximum daily Project emissions estimates were calculated assuming implementation of mitigation measure and a more refined equipment inventory and schedule, with the results presented below in Table 2-2. Use of the Cold Canyon Landfill for the disposal of NHIS would result in lower Project emissions and, in this case, revised emissions spreadsheets would be provided to SLOAPCD.

The air quality emissions model included in Appendix F provides a break-down of offsite trucking expected to occur as a result of the Project. Offsite trucking will include the import of equipment, gravel, and geo-textile materials to the Project Site, as well as commuter trips. Export transportation will include NHIS soil, demolition debris, and scrap metal from the Project Site to the designated disposal locations. The designated disposal locations utilized in the model include Santa Maria Regional Landfill for 100% of NHIS soil and demolition debris. The timing of import and export trucking activities are linked in the model to the timing of remediation activities, the ten year project construction schedule summarized in Table 1-1, and the estimated waste volumes listed in Table 1-2. The daily average trips for each specific activity were calculated by dividing the total number of truck trips by the duration of a specific activity. Peak day trips for a specific activity were calculated by rounding up the average per day trips to the nearest integer. Refer to the Peak Offsite Emissions, Offsite, and Schedule sheets of the air quality model included as Appendix F. The Project will exceed SLOAPCD’s threshold for requiring Best Available Control Technology (BACT). Refer to the following sections for a list of proposed emissions reduction measures. The Project will also exceed SLOAPCD’s Tier II threshold for offsite mitigation requirements (6.3 tons/quarter), which requires funding or implementation of ROG+NOx reducing projects within San Luis Obispo County (known as the Moyer value). Appendix F (Peak Offsite Emissions Sheet) presents the estimated total payments due over the course of the Project, estimated to be $636,229.38. Chevron has submitted an initial payment to SLOAPCD for offset mitigation funding. Additional payments will be made on an annual basis and will be paid by Chevron ahead of the actual air quality impact occurrence. Please note that the Project schedule is subject to change due to factors including changes in equipment model, engine year, schedule, and yearly adjustments to the Moyer value. Chevron will provide the SLOAPCD with quarterly reports on the actual air quality impacts resulting from Project construction equipment emissions and will make future off-set mitigation payments accordingly. Chevron San Luis Obispo Tank Farm Remediation and Restoration Project Construction Activity Management Plan Project No. 1301-0306 3-1 - 3.0 CONSTRUCTION EQUIPMENT EMISSION REDUCTIONS (NOX AND PM10) The following standard combustion emissions reduction and BACT measures will be implemented during the Project. Equipment scheduling measures are also presented in this section. 3.1 PERMITTING REQUIREMENTS Chevron will submit an ATC/PTO application to SLOAPCD for the remediation and restoration activities, such as pipeline decommissioning activities and affected soil management activities. As feasible, work on each of the former reservoir areas will be conducted sequentially to keep emissions under quarterly thresholds. An Air Quality Monitoring Plan has also been developed for these activities and is included as Appendix C. A Human Health Risk Assessment HRA) to evaluate impacts from Project activities to potential receptors has been prepared and submitted to SLOAPCD separately. The following list is provided as a guide to equipment and operations that could reasonably be anticipated at the Project Site and may have permitting requirements through the state-wide Portable Engine Registration Permit (PERP). If an onsite water treatment system for dewatering becomes necessary, it will utilize electric pumps with electricity supplied from a nearby overhead electrical drop, if feasible. A list of portable engines anticipated to be utilized at the Project Site is presented below: Power screens, conveyors, welding machines; and Portable generators and equipment with 50-horsepower or greater engines. 3.2 EQUIPMENT SCHEDULING (NOX AND PM10) As discussed above, the Project work will be scheduled for sequential work on each reservoir area as feasible. Construction-related highway traffic will be governed by a Traffic Management Plan, which includes restricted truck travel during daily peak hours (Padre, 2016b). 3.3 CONSTRUCTION WORKER TRIPS The Project-specific Traffic Management Plan addresses the CUP required for a park and ride program to reduce the number of single occupant vehicle trips going to the Project Site. 3.4 COMBUSTION EMISSIONS REDUCTION MEASURES Chevron will implement the following nitrogen oxide (NOx) and reactive organic gasses ROG) reduction measures in accordance with the County CUP Conditions of Approval (refer to Appendix A). Additionally, Chevron has included the following additional measures to reduce construction related emissions: All equipment will utilize Tier IV engines (or equivalent), if feasible; Additional Best Available Control Technology for Toxics (TBACT) measures as required by the HRA; and Chevron San Luis Obispo Tank Farm Remediation and Restoration Project Construction Activity Management Plan Project No. 1301-0306 3-2 - Overhead electrical service will be utilized to supply electrical power to the following equipment, if feasible: water treatment system pumps and controls, job shacks, and plant growing facility. Chevron San Luis Obispo Tank Farm Remediation and Restoration Project Construction Activity Management Plan Project No. 1301-0306 4-1 - 4.0 CONSTRUCTION DUST MITIGATION Chevron plans to disturb approximately 112 acres of the Project Site during the course of the Project. A geologic evaluation completed at the Project Site did not indicate the presence of asbestos above the analytical detection limit of 0.25% in any of the rock or soil samples analyzed by California Air Resources Board Method 435. However, microscopic analyses indicated that several rock core samples contained trace concentrations of chrysotile asbestos which could not be quantified due to the method quantification criteria (Padre, 2012). Recent sampling and analysis completed by Padre indicates that the quarry area materials did not contain detectable asbestos concentrations with a laboratory analytical detection limit of 0.1%. Refer to Appendix D for copies of the naturally-occurring asbestos (NOA) sampling reports and correspondence. NOA may be encountered during soil excavation and screening activities at the Project Site. Perimeter air monitoring and personal exposure air monitoring will be completed during the disturbance of soils at the Flower Mound and other areas (if NOA is identified) in accordance with the attached NOA Air Monitoring Plan (Appendix D). If monitoring results indicate that the trigger levels are exceeded, then additional asbestos dust control measures presented in the CAMP will be implemented until adequate asbestos dust emissions control is achieved. This section describes soil monitoring activities to be completed during ground disturbance activities and the dust control measures that will be used to minimize the emissions of dust generated during construction activities, including the potential for asbestos-containing dust. For each type of construction activity, several control measures are described. Additional measures are included for areas with NOA. 4.1 SOIL MANAGEMENT AND DUST CONTROL The generation of dust during the remedial activities at the Project Site will be minimized and controlled by the application of dust control measures. Activities such as stockpiling soil, construction vehicle traffic, and wind blowing over disturbed soil may generate dust and particulate matter when the exposed soil surfaces are dry. The following measures will be utilized for soil stockpile management: Cover excavations with plastic sheeting at the end of each work day. Chevron also proposes to alternatively use a soil tackifier as an alternative to plastic sheeting to meet this requirement; Contaminated soil will be covered with an impermeable material such as plastic sheeting or sprayed with an encapsulating material such as Soil Sement. No headspace will be allowed by the covering where vapors could accumulate; Covers on storage piles will be maintained in place at all times in areas not actively involved in soil addition or removal; Covered piles will be designed in such a way to eliminate erosion due to water or public nuisance; During soil excavation, odors will not be evident to such a degree as to cause a public nuisance; and Chevron San Luis Obispo Tank Farm Remediation and Restoration Project Construction Activity Management Plan Project No. 1301-0306 4-2 - Clean soil will be segregated from contaminated soil. The following dust control measures will be utilized throughout the Project activities: Reduce the amount of the disturbed area where possible; Use of water trucks or sprinkler systems in sufficient quantities to prevent airborne dust from leaving the site. Increased watering frequency would be required whenever wind speeds exceed 15 miles per hour (mph). Reclaimed (non-potable) water will be used when practical; All dirt stock pile areas will be sprayed daily as needed; Permanent dust control measures identified in the approved Project revegetation and landscape plans will be implemented as soon as possible, following completion of any soil disturbing activities; Exposed ground areas that are planned to be reworked at dates greater than one month after initial grading will be either sprayed with soil binders or sown with a fast germinating, non-invasive, grass seed and watered until vegetation is established; All disturbed soil areas not subject to revegetation will be stabilized using approved chemical soil binders, jute netting, or other methods approved in advance by the SLOAPCD; All roadways, driveways, sidewalks, etc. to be paved will be completed as soon as possible. In addition, building pads will be laid as soon as possible after grading unless seeding or soil binders are used; Vehicle speed for all construction vehicles will not exceed 15 mph on any unpaved surface at the construction site; All trucks hauling dirt, sand, soil, or other loose materials are to be covered or will maintain at least two feet of freeboard (minimum vertical distance between top of load and top of trailer) in accordance with CVC Section 23114; Install rumble strips where vehicles enter and exit unpaved roads onto streets, or wash off trucks and equipment leaving the site; Sweep streets at the end of each day if visible soil material is carried onto adjacent paved roads. Water sweepers with reclaimed water will be used where feasible; All PM10 mitigation measures required will be shown on grading and building plans; and, The contractor or builder will designate a person or persons to monitor the fugitive dust emissions and enhance the implementation of the measures as necessary to minimize dust complaints, reduce visible emissions below 10% opacity, and to prevent transport of dust offsite. Their duties will include availability on holidays and weekend periods when work may not be in progress. The name and telephone number of such persons will be provided to the SLOAPCD Compliance Division prior to the start of any grading, earthwork or demolition. Chevron San Luis Obispo Tank Farm Remediation and Restoration Project Construction Activity Management Plan Project No. 1301-0306 4-3 - 4.1.1 Contingency Measures In the event that the Project produces nuisance complaints from the neighbors or the general public, contingency measures will be taken to eliminate the nuisance potential. These measures include: Increase watering to reduce dust emissions; Use of alternate soil management. This will allow for flexibility for which site will be used depending on wind direction and intensity; or Suspended stockpiling activities and immediate covering of active stockpiles with plastic sheeting. 4.1.2 Additional Dust Control Measures for NOA Areas NOA may occur at the former quarry area of the Project Site. Therefore, overburden removal within the former quarry area and other areas with the potential to contain NOA must proceed initially as if it contains NOA and must utilize dust control measures that are described below. Additionally, a Professional Geologist (or his designee) will visually monitor the work to determine whether serpentine or NOA are potentially present with the work area. Refer to the NOA Air Monitoring Plan for more information on NOA monitoring activities. Activities that could generate dust emissions containing asbestos include clearing and grubbing, blasting, earthmoving activities, such as stripping top soil, excavation, stockpiling, and placing soil material. Basic construction and grading operations control measures will include: 1. Prior to any ground disturbance, work areas will be kept adequately wet to minimize visible emissions from crossing the limits of work. The "perimeter" monitoring boundary is defined as the San Luis Obispo Tank Farm property boundary or work area boundary when outside of Chevron property. 2. Areas to be graded or excavated will be kept adequately wet to prevent visible emissions from crossing the perimeter monitoring line. Adequately wet areas will produce no visible dust emissions as determined by the onsite Chevron representative. 3. As needed, the regulated and non-regulated work areas will be restricted to only authorized, trained and protected personnel, as needed. Regulated work areas are those work areas where airborne asbestos fiber concentrations exceed or may exceed the Permissible Exposure Limits (PELs). A list of authorized personal (include names, addresses and local telephone numbers) will be established and posted prior to the commencement of work activities and maintained throughout the duration of the work. The name and contact information of the Contractor Foreman and the Asbestos Competent Person will be included on this list. 4. Warning signs and barrier tape designating regulated work areas are to be installed, maintained, checked and repaired or replaced as necessary to maintain proper warnings at all work areas. Other health and safety issues will be appropriately addressed in the project-specific health and safety plan (HASP). 5. A worker decontamination area will be designated adjacent to each regulated construction activity work area. If non-contiguous to the construction activity work area, Chevron San Luis Obispo Tank Farm Remediation and Restoration Project Construction Activity Management Plan Project No. 1301-0306 4-4 - the decontamination area will be located so that workers are not required to use public streets or sidewalks to cross-occupied or privately owned property to access the decontamination area. 6. Active storage piles will be kept adequately wet or treated with a chemical dust suppressant, or covered when material is not being added to or removed from the pile. Covers, when used, will be physically secure and maintained throughout their use. 7. Non-active storage piles and other disturbed surface areas that will remain inactive for more than seven days will be maintained as described in Section 5.4 of the AQMP. 8. Haul roads within the former quarry area will be kept adequately wet while in use. 9. Construction vehicle speed in areas containing NOA will be limited to 15 mph or less. Vehicles hauling NOA-containing materials outside of NOA-containing areas will be wetted and/or covered such that no visible emissions are generated during hauling and will also be limited to a speed limit of 15 mph. Under no circumstances will haul trucks be allowed to transport NOA-containing materials in a manner that allows visible emissions from either the wheels or the load of the truck. 10. The Asbestos Competent Person will conduct a visual clearance inspection of the construction activity work areas twice daily. The inspections will take place at the beginning and at the end of each shift to confirm that all asbestos containing soil is property contained. The inspections will also assure that the barrier tapes, posting, decontamination systems and all other work area components and equipment are intact and in good working order. The Contractor will maintain inspections of the regulated work areas until a written report of Project Site clearance has been obtained from the Asbestos Competent Person. 11. If worn, Personal Protective Equipment (PPE) will comply with 8 CCR 1509-1527 (as applicable), 5144, 5208, and 1529.10.2. If worn, full-body disposable protective clothing will include head, body, and foot coverings and consist of material resistant to penetration by asbestos fibers. If protective clothing is required, it will be provided to all workers in sizes large enough to allow movement without tearing. The following criteria regarding PPE at the Project Site is required: Workers and authorized visitor entering and working in the regulated work area must wear respiratory protection, if required; If worn, respiratory protection must be National Institute of Occupational Safety and Health (NIOSH) approved; and Respirator cartridges must protect against all air borne particulate (P-100) and may need to protect against organic vapors. Additional safety equipment, as necessary, will be provided to all workers and authorized visitors. This equipment may include, but not be limited to, rubber work boots, work gloves, safety glasses, orange reflective vests, and hard-hats. 4.1.3 Onsite Track-out Control Measures Generally, construction vehicles will exit a NOA-containing area and travel on non NOA- containing gravel roads within the limits of work. For example, trucks may collect material from an excavation area and take the material to a disposal area, using an access road made of non NOA- Chevron San Luis Obispo Tank Farm Remediation and Restoration Project Construction Activity Management Plan Project No. 1301-0306 4-5 - containing material. To prevent track out of NOA, the following Air borne Toxic Control Measures ATCM) requirements will be followed for onsite roads: 1. A maximum vehicle speed limit of 15 mph or less; and 2. One or more of the following: i. Watering every two hours of active operations or sufficiently often to keep the area adequately wetted; ii. Applying chemical dust suppressants consistent with manufacturer's directions; iii. Maintaining a gravel cover with a silt content that is less than five percent and asbestos content that is less than 0.25 percent, as determined using an approved asbestos bulk test method, to a depth of three inches on the surface being used for travel; or iv. Any other measure as effective as the measures listed above. 4.1.4 Track-Out onto Public Roads It will be necessary for trucks and other equipment to leave the Project Site and travel on public roads. In the event vehicles will exit the Project Site to a public paved road from a NOA- containing area, a system will be utilized to prevent offsite migration of soil. Track-out prevention and control measures will include: 1. Removal of any visible track-out from a paved public road at any location where vehicles exit the Project Site; this will be accomplished using wet sweeping or a high efficiency particle air (HEPA) filter or equivalent particulate filter equipped vacuum device at the end of the work day or at least one time per day, and 2. Installation of one or more of the following track-out prevention measures: i. A gravel pad or rumble strips designed using good engineering practices to clean the tires of exiting vehicles; ii. A tire shaker; iii. A wheel wash system; iv. Pavement extending for not less than fifty consecutive feet from the intersection with the paved public road; or v. Any other measure as effective as the measures listed above. Soil contaminated with petroleum hydrocarbons will be excavated and removed for offsite disposal. Some of this soil may contain NOA, meaning NOA-containing soil may be removed from the Project Site for offsite disposal at a designated landfill. 4.1.5 Offsite Transportation of NOA Containing Materials The offsite transport of NOA-containing materials as NHIS material is not anticipated, but could occur. The Contractor will implement the ACTM requirements for loading and transporting NOA material, as stated below: Chevron San Luis Obispo Tank Farm Remediation and Restoration Project Construction Activity Management Plan Project No. 1301-0306 4-6 - 1. Trucks are maintained such that no spillage can occur from holes or other openings in cargo compartments; and 2. Loads are adequately wetted and either: i. Covered with tarps; or ii. Loaded such that the material does not touch the front, back, or sides of the cargo compartment at any point less than six inches from the top and that no point of the load extends above the top of the cargo compartment. 4.1.6 Post Construction Stabilization of Disturbed Areas The ATCM requires post construction stabilization of disturbed surfaces of NOA-containing materials greater than 0.25 percent asbestos using one or more of the following methods: 1. Establishment of a vegetative cover; 2. Placement of at least three inches of non-asbestos-containing material; 3. Paving in areas that will not be inundated with storm water or reservoir water; and 4. Any other measure deemed sufficient to prevent wind speeds of 10 mph or greater from causing visible dust emissions. 4.2 LEAD AND ASBESTOS-CONTAINING BUILDING MATERIALS There are four buildings at the Project Site, located in the Northwest Operations Area, that will be demolished during the course of remediation activities. Given the age of the three older buildings, Chevron surveyed these buildings for lead-containing and asbestos-containing materials and found that they are present (West Coast Safety Consultants, 2008). Asbestos abatement activities were completed on the southern two buildings in 2009. Additional asbestos and lead abatement will be needed prior to physical demolition of the buildings. In 2015, Padre completed an asbestos survey of concrete structures, footings and debris at the Project Site. Padre identified asbestos-containing materials in transite and gasket material identified during the course of the survey. None of the concrete structures or foundations were identified with asbestos concentrations in excess of the laboratory detection limit of 0.25 percent (Padre, 2015a). Prior to abatement, a National Emissions Standard for Hazardous Air Pollutants (NESHAP) demolition notification form, asbestos survey report, and an asbestos abatement work plan will be submitted to the SLOAPCD. Asbestos-containing materials will be abated in accordance with local, state, and federal regulations. Any suspect material found during abatement and not previously identified will be presumed asbestos-containing materials unless contradicted by specific laboratory data. Asbestos-containing materials will be properly wrapped, placed in covered roll-off bins, and disposed of at a licensed disposal facility in accordance with the Project’s Waste Management Plan (Padre, 2015c). During building demolition and concrete debris removal, water spray will be actively applied to the work area. Loose or flaking lead-based paint will be scraped by a licensed and trained contractor prior to demolition of the buildings. Intact lead-based painted materials will be sprayed with an encapsulating material prior to demolition. Paint chips dislodged during demolition activities will be collected and properly disposed. Chevron San Luis Obispo Tank Farm Remediation and Restoration Project Construction Activity Management Plan Project No. 1301-0306 4-7 - All pipeline segments scheduled for removal that contain coatings or wrap will be inspected by a CAC or CSST working under the auspices of a CAC for the presence of asbestos-containing materials. Asbestos-containing material will be removed by properly trained personnel. Pipe with somastic coating and pipe fittings containing asbestos-containing flange gaskets will be disposed of as asbestos waste. Should friable material, or material that could become friable, be discovered during the course of Project activities, Chevron will stop work and an asbestos abatement work plan will be submitted to SLOAPCD for review and approval. All asbestos containing material (ACM) waste will be wrapped in plastic sheeting and taped to prevent the disturbance or release of somastic material. Any flanges containing ACM gaskets will be placed in plastic bags and sealed. All asbestos waste will be placed in designated asbestos waste roll-off bins which are labeled as containing asbestos waste. As the work progresses, to prevent exceeding available storage capacity onsite, sealed and labeled containers of asbestos containing waste shall be removed and transported to the prearranged disposal location. Disposal shall occur at an authorized site in accordance with regulatory requirements of NESHAP and applicable State and local guidelines and regulations.

Table 5-1 will be followed for the re-use or import of materials within the open space and development areas of the Project Site within the upper-most levels (upper two-feet for open space or four-feet for development areas). Materials not meeting the criteria provided below will be either utilized in selected deeper fill areas or transported offsite for disposal at a licensed facility. The primary fill areas include the former Northwest Operations area and Reservoir 4. It should be noted that RBSLs do not apply to asphaltic material that is inseparably embedded in the soil matrix at designated borrow source locations at the Project Site. This material does not warrant remediation and may be utilized as fill material in accordance with the RAP.

(Padre), on behalf of Chevron Environmental Management Company (Chevron) has prepared this Traffic Management Plan (TMP) for the remediation and restoration activities planned at the former Union Oil San Luis Obispo Tank Farm Site (Project Site). This TMP identifies and addresses off-site project-related traffic requirements for the San Luis Obispo (SLO) Tank Farm Restoration and Remediation Project planned at the Project Site. The location of the Project Site is presented as Figure 1-1 - Site Vicinity Map, and Figure 1-2 – Site Plan. Figure 1-3 provides an illustration of the proposed work areas. Items discussed in this TMP includes local traffic control measures, haul routes, peak hour and route restrictions, and road monitoring program. Emergency response procedures are provided in separate plans. Traffic to and from the Project Site will primarily consist of trips by site workers, deliveries of equipment and materials, and transportation for beneficial re-use of non-hazardous hydrocarbon impacted soil (NHIS) from the Project Site. An estimated 160,000 cubic yards of affected material will be transported off-site during the duration of this project. Given the uncertainties of remediation projects, the Final EIR evaluated the impacts for off-site transport of 196,250 cubic yards of affected material (the estimated 160,000 cubic yards plus a 25% contingency). Up to 60 truck round trips maximum are anticipated, with an average of approximately 20 round trips anticipated during an active day of steady hauling. The Final EIR evaluated a very conservative case of 177 truck round trips per day, which assumed that three large excavation and hauling projects would be implemented concurrently. Additionally, up to 87,000 cubic yards of gravel will be imported to the Project Site. Approximately 20 auto daily round trips are expected for employees on the Project Site during this time. 1.1 SITE DESCRIPTION The Project Site is located immediately south of the city of San Luis Obispo, San Luis Obispo County, California. The address of the Project Site is 276 Tank Farm Road. The Project Site is divided into north and south sections by Tank Farm Road, and is bordered by light commercial and industrial development to the west; the San Luis Obispo County Regional Airport to the southeast; agricultural and pastoral lands with scattered residences to the south; and a mobile home park to the east. The existing buildings in the northwest part of the Project Site are used as Chevron’s local offices. The buildings are proposed for demolition as part of the Project. 1.2 SITE BACKGROUND This Project Site was originally owned and operated by Union Oil of California (Union Oil). Chevron purchased Union, including the Project Site, in August 2005. The San Luis Obispo Tank Farm was constructed in 1910 to serve as the accumulation point for the petroleum pipeline from the San Joaquin Valley. In 1926 many of the tanks on the Project Site were destroyed in a fire caused by a lightning strike. The San Luis Obispo Tank Farm was re-built and operated until the 1970s. The Project Site was slowly withdrawn from operation during the later decades of the twentieth century, and by the late 1990s it was formally decommissioned. 2 Chevron San Luis Obispo Tank Farm Remediation and Restoration Project Traffic Management Plan Project No. 1301-0306 The Project Site now exists as a primarily vacant land that is effectively surrounded by the urban development within the City of San Luis Obispo and the San Luis Obispo County Regional Airport area. 1.3 CONDITIONAL USE PERMIT / CONDITIONS OF APPROVAL This Plan has been prepared for the purpose of complying with the Conditional Use Permit (CUP) (DRC2013-00056) and to support information and/or requirements presented in the Final Environmental Impact Report (FEIR), certified by the City of San Luis Obispo (Marine Research Specialists, 2013). Specifically, this Plan has been prepared following Conditions 59 and 103 of the San Luis Obispo County CUP (DRC2013-00056), Conditions of Approval, Exhibit B. Conditions 59 and 130 are as follows: 59 T-1: Prior to issuance of applicable construction permits, the applicant shall develop a construction traffic management plan for review and approval by the County Public Works department in consultation with City Public Works and Caltrans.

The soil material to be hauled off-site is primarily classified as NHIS and will be hauled to the Santa Maria Regional Landfill-NHIS facility or, upon addition to the CUP, Cold Canyon Landfill. The material has been profiled and meets the acceptance criteria for the Santa Maria Regional Landfill (NHIS program). Limited amounts of soil and waste may also be shipped to the Buttonwillow Hazardous Waste Facility, and the Kettleman Hills Hazardous Waste Facility. Cold Canyon Landfill has been identified as a possible alternative soil and non-hazardous waste disposal location. Demolition debris and other non-hazardous waste will be shipped to the Cold Canyon Landfill or the Santa Maria Regional Landfill. Additional facilities will be utilized on a limited basis as needed for recyclable or waste shipments. The following are the locations and contact information for the identified facilities: 2.1 SANTA MARIA REGIONAL LANDFILL-NHIS PROGRAM 2065 E.

Equipment delivered to the Project Site will primarily consist of construction equipment. Materials delivered to the Project Site will include gravel, general construction supplies, materials, and fuel for vehicles. Vehicles transporting construction materials will generally follow the same circulation pattern as shown on Figure 4-1. 3.2 HAULING IMPORT AND EXPORT MATERIAL An estimated 160,000 cubic yards of affected material will be transported off-site during the duration of this Project. Additionally, up to 87,000 cubic yards of gravel will be imported to the Project Site. Assuming a typical capacity of 15 cubic yards per truck, this corresponds to 10,667 round trips for materials export and 5,800 round trips for materials import. Up to 60 truck round trips maximum are anticipated, with an average of approximately 20 round trips anticipated during an active day of steady hauling. These trips are expected to occur over a ten-year period. Prior to leaving the Project Site, trucks exporting NHIS material will be securely tarped and issued a non-hazardous waste manifest. Chevron has received a haul permit from the City of Santa Maria and Santa Barbara County (attached as Appendix B). 3.3 TRAFFIC CONTROL Traffic control measures will be conducted in accordance with Caltrans specifications. An encroachment permit will be obtained from San Luis Obispo County Public Works Department for the construction of shoulder areas and driveway approaches at the Project Site entrances. Berms in the southern edge of Tank Farm Road will also be removed to provide shoulder areas and improve site distance. The shoulder areas will allow trucks to pull out of the traffic lanes while turning to enter the Project Site. The south entrance gate will be moved back approximately 100 feet from Tank Farm Road to provide space for the trucks to park at the gate without blocking traffic using Tank Farm Road. Portable electronic message signs will be placed on each end of the Project Site along Tank Farm Road during times when project activities will impact Tank Farm Road to the extent that traffic control is needed. The electronic message signs will provide the traveling public with current construction information and the availability of alternate travel routes. Refer to Appendix A for the proposed message sign locations and messages. Traffic control devices (barricades, signs) will be placed as to not interfere with bicyclists or pedestrians traveling on Tank Farm Road. Traffic control plans have been developed for the construction of the shoulders and driveway approaches and for controlling traffic along Tank Farm Road at three points of access to the Project Site both before and after the shoulders and driveway approaches are constructed. Refer to Appendix A – Traffic Control Plans. Temporary traffic stops to allow haul vehicles to leave the Project site will occur at only one location at any one time. Traffic stops shall be of short duration to minimize disruption of Tank Farm Road traffic and to reduce “platooning” of haul trucks. 9 Chevron San Luis Obispo Tank Farm Remediation and Restoration Project Traffic Management Plan Project No. 1301-0306 Lane closure activities on Tank Farm Road are restricted to between 8:30 a.m. and 4:00 p.m. in accordance with Appendix E3 of the County of San Luis Obispo 2014 Public Improvement Standards. Caltrans has also requested that soil hauling occur on its roads between 8:30 a.m. and 3:00 p.m., and that no soil hauling activities occur on holidays as presented in Table 1 – Designated Legal Holidays or on the day before a Designated Legal Holiday. If a Designated Legal Holiday is on a weekend or Monday, no hauling will occur on the Friday before the holiday. Deliveries and export of material will be scheduled to avoid peak traffic hours and special events. Table 1. Designated Legal Holidays Holiday Date New Year’s Day January 1 Martin Luther King Jr. Day Third Monday in January Washington’s Birthday Third Monday in February Memorial Day Last Monday in May Independence Day July 4 Labor Day First Monday in September Veteran’s Day November 11 Thanksgiving Day Fourth Thursday and Friday in November Christmas Day December 25 Note: When a designated legal holiday falls on a Sunday, the following Monday shall be a designated legal holiday. When November 11th falls on a Saturday, Friday November 10th shall be a designated legal holiday. 10 Chevron San Luis Obispo Tank Farm Remediation and Restoration Project Traffic Management Plan Project No. 1301-0306 3.4 OVERSIZED OR OVERWEIGHT REQUIREMENTS A Caltrans Transportation Permit will be obtained prior to the shipment of any oversized or over- weight loads during the course of the Project activities. http://www.dot.ca.gov/trafficops/permits/). 3.5 EMISSIONS REDUCTION PLAN In accordance with the County’s Conditions of Approval, Chevron will implement a park and ride program to reduce the number of worker single occupant vehicle trips going to the Project Site. The goals of a park and ride program include decreasing the number of vehicle trips, decreasing the air pollution associated with transportation, and decreasing traffic congestion near the Project Site. Applicable requirements in additional agency-required plans intended to reduce dust and emissions (e.g., dust control, emissions reduction measures) will also be followed. Refer to the Construction Activity Management Plan (CAMP) (Padre, 2016) for more information on these air quality-related measures. 3.6 EMERGENCY VEHICLE ACCESS Advance notification will be provided to emergency response providers near the Project Site with construction locations, potential lane closure schedules, and potential alternate routes in order to avoid disruption to fire protection services' access through the area. The prepared notification will be submitted to local emergency providers listed in Table 2: Table 2.

The pavement monitoring program for each jurisdiction is outlined below. 5.1 COUNTY ROADS A Chevron representative will monitor pavement conditions on roadways used for Project-related hauling activities. According to a County roadway condition report provided by Glenn Marshall, Tank Farm Road within County jurisdiction currently has a pavement condition index of 80, as measured on September 10, 2013. Roadway damage or debris on County roads resulting from the Remediation Project will be addressed immediately and corrected in consultation with the County Public Works departments or, if appropriate, Caltrans. The following lists the planned elements of the Pavement Monitoring Program for the County-maintained portion of Tank Farm Road to be used for project-related hauling: 1. Pre-construction inspection and marking of pre-existing road damage with white spray paint (if safe and appropriate to do so). The location, width, and length of damaged roadways will be recorded and a tabulation of existing roadway damages will be submitted to the County Planning and Building Department Project Manager and the County Public Works Department. 2. Pre-construction videotaping using a video camera attached to a moving vehicle and traveling at low speed. The pre-construction video recording of each segment will be completed within two weeks prior to the start of hauling activities for each year of project-related construction activities. 3. Daily monitoring for debris track-out and removal of such material in accordance with Best Management Practices (Caltrans SC-7 or CASQA SE-7). 4. Bi-weekly monitoring of pavement condition via visual inspection. Videotaping may also be done intermittently at Chevron’s discretion. 5. Post-construction inspection and videotaping completed within two weeks after the end of project-related hauling activities each year to identify and document damage related to hauling activities. The location, width, and length of roadway area(s) potentially damaged by project-related hauling will be recorded and a comparison of pre- versus post-construction roadway damages will be submitted to the County Planning and Building Department Project Manager and the County Public Works Department. 6. Chevron will repair damage resulting from its project-related hauling activities. As needed, pavement will be repaired with “cold patches” within 24-hours of discovery by Chevron or notification by the County or its representatives. Repair work will be conducted under the County’s existing encroachment permit and, a) will be done in accordance with applicable County standards and specification, Chapter 5.5 of Division 2 of the California Streets and Highways code, Division 15 of the California Vehicle Code, and with Encroachment Permit; b) will be performed by an appropriately licensed and bonded contractor; and c) will be undertaken with 15 Chevron San Luis Obispo Tank Farm Remediation and Restoration Project Traffic Management Plan Project No. 1301-0306 appropriate traffic control per the latest California Manual of Uniform Traffic Control Devices. If Chevron is not able to complete the repairs within 24 hours, it may arrange to pay the County’s cost to perform the work. 7. Complaints should be directed to: Jerry Conable, Field Construction Representative, Chevron Environmental Management Company Office phone - (805) 546-6912 Cell phone – (925) 999-0201 Email - JConable@chevron.com Andy Smith, Project Manager, Chevron Environmental Management Company Office phone - (805) 546-6915 Cell phone – (805) 540-9812 Email - smith.andy@chevron.com 5.2 CITY ROADS The City of San Luis Obispo has established a fee-based road program for roads under its jurisdiction, including its portions of Tank Farm Road. The fee will be paid in lieu of inspections, monitoring and repairs by Chevron on any City-maintained roads. During the permit processing for each upcoming area of work, Chevron will determine the cubic yards of soils to be hauled offsite and gravel to be imported and will estimate the associated number of truck round trips. Prior to issuance of the construction permit by the County, Chevron will pay the City a fee of $1.50 per round trip. 16 Chevron San Luis Obispo Tank Farm Remediation and Restoration Project Traffic Management Plan Project No. 1301-0306 6.0 REFERENCES Avocet Environmental, Inc., 2015.

The objective of this WMP is to assist Project Site personnel in the onsite management and offsite transportation and disposal of waste streams generated at the Project Site in accordance with applicable regulatory and project specific permit requirements. Specific goals of this WMP are to: Outline regulatory, permit, and CEMC/Refining Business Unit (RBU) requirements associated with waste management; Provide Project Site personnel information and guidance needed to properly handle, manage, and dispose of previously identified hazardous and non hazardous waste; Provide Project Site personnel information and guidance needed to identify, characterize, manage, and dispose of newly identified hazardous and non hazardous waste; Describe documentation and recordkeeping associated with waste management activities; and Provide guidance to minimize waste generation and enhance re use and recycling. Using guidance provided in this plan will allow Project Site field personnel to effectively manage wastes generated by their operations. However, this guidance is not intended to hamper communications between the Project Site field personnel and Project Site Waste Coordinator Group and site management. When questions arise, compliance and/or management groups should be contacted to ensure compliance. In addition, this document can be amended in the field, as necessary. All revisions and amendments must be documented in the Revision and Approval section of this WMP (page ii) and approved by the Waste Management Coordinator and the CEMC Project Manager or their designee. The information, content, and guidance presented in this WMP have been prepared to address local, state, and federal statutes and regulations as well as project specific permits, plans, and CEMC requirements. These statutes and regulations, project specific requirements, and interpretations may change; therefore, this document may be revised and updated as necessary. 2 - Chevron San Luis Obispo Tank Farm Remediation and Restoration Project Waste Management Plan Project No. 1301-0304 Figure 1-1.

The introduction should include, at the least, an overview of waste manifesting procedures, requirements, and key contacts. 3.2 HEALTH AND SAFETY REQUIREMENTS All Project Site waste handlers must be familiar with and implement the following health and safety procedures during waste management activities particularly during identification, packaging, sampling, or similar activities where exposure is likely. Review Safety Data Sheet (SDS) for chemicals suspected to be in the waste; Refer to health and safety requirements specific to field operations and the task being performed, and don appropriate personal protective equipment (PPE); Drums or totes containing waste should never be lifted by hand; use proper waste handling equipment; Follow confined space entry standard in enclosed areas if necessary to access waste; If unsafe conditions or items needing repair are noted, contact the Project Site Waste Coordinator or immediate supervisor and take appropriate corrective action; and Contact the Project Site Waste Coordinator or immediate supervisor if uncertainties exist. 10 - Chevron San Luis Obispo Tank Farm Remediation and Restoration Project Waste Management Plan Project No. 1301-0304 4.0 WASTE CLASSIFICATION Waste classification begins when a waste is generated and should be consistent with applicable federal and state regulations including 40 CFR 261 and Title 22 CCR Chapter 11. Waste material generated at the Project Site may be classified as hazardous waste, “California” hazardous waste, non hazardous waste, Universal Waste, recyclable materials, or municipal waste as described in the following sections. Hazardous or non hazardous classifications are determined by the type and amount of hazardous components of the waste. This determination is accomplished through sampling and analytical testing to evaluate the concentration of suspected contaminants. Analytical testing is required if previous testing was not performed, test results are inadequate or outdated, or other information sources such as SDSs do not provide sufficient data to determine proper disposal. Waste classification information also determines applicable waste codes, proper storage procedures, DOT shipping and labeling requirements, and the data necessary for acceptance at disposal/recycling facilities. The following sections describe the various waste classifications and lists specific waste that are routinely generated at the Project Site in each classification. Table 4-1 summarizes various waste streams that may be generated, onsite storage and handling requirements and approved offsite disposal facilities. Table 4-1 Waste Management Inventory Program, San Luis Obispo Tank Farm, San Luis Obispo, California, Waste Assessment Criteria TYPE OF WASTE ANALYSIS AND PROFILE REQUIRED FINAL DISPOSITION Wood debris with lead-based paint Title 22 Waste Profile Analyses for Disposal at Clean Harbors or Chemical Waste Management Facility Contain in roll-off bin(s) pending profile acceptance.

Investigation Derived Waste soil, water, and disposable PPE) Title 22 Dispose of at Clean Harbors as Non-Hazardous waste, depending on analytical results. Review work order and profile from Clean Harbors and ensure still valid. Universal Waste None Place in 5-gallon buckets, 55-gallon drums, or necessary size container and transport to Clean Harbors or local municipal recycling facility. 4.1 HAZARDOUS WASTE Waste is considered characteristically hazardous if it exceeds the federal and/or state regulatory levels for ignitability, corrosivity, reactivity, or toxicity characteristics as defined in 40 CFR 261 Subpart B and Title 22 CCR, Division 4.5, Chapter 11, Article 3. A waste may be identified as characteristically hazardous by laboratory analysis or generator knowledge. In addition, certain wastes have been determined to be hazardous by the federal and state agencies based on concentration of chemicals that would render it hazardous and the process or industry that created the waste, and have been “listed” as such in 40 CFR 261 Subpart C and Title 22 CCR, Division 4.5, Chapter 11, Article 4. Listed waste may be from a non specific source (not industry specific), a specific source, or may be discarded commercial chemical products, off specification species and spill residue. According to the “Listed Mixture Rule”, any waste mixture that includes a listed hazardous waste is automatically a listed hazardous waste and will carry the listing. Material deemed to be hazardous waste must be placed in the designated storage location (refer to Figure 4-1); properly labeled; and disposed of at a Chevron-approved treatment, storage, and disposal facility (TSDF) authorized for hazardous waste disposal (Class I) accompanied by a hazardous waste manifest and LDR form (when applicable). The date hazardous material is placed in the storage location must be clearly marked on the label to ensure it is stored onsite for 180 days or less. Examples of waste generated at the Project Site 12 - Chevron San Luis Obispo Tank Farm Remediation and Restoration Project Waste Management Plan Project No. 1301-0304 that may be considered hazardous include the following. Refer to Table 4-1 for additional waste and specific handling requirements. Soil containing heavy metals or volatile organic compounds (VOCs) in concentrations greater than the regulatory toxicity characteristics thresholds; Polychlorinated Biphenyls; Lead based paints; and Discarded commercial chemical products. 13 - Chevron San Luis Obispo Tank Farm Remediation and Restoration Project Waste Management Plan Project No. 1301-0304 Figure 4-1. Designated Storage Location 14 - Chevron San Luis Obispo Tank Farm Remediation and Restoration Project Waste Management Plan Project No. 1301-0304 4.2 NON HAZARDOUS WASTE The majority of waste generated at the Project Site is considered non hazardous waste. Unless otherwise stated in project specific plans, non-hazardous waste will be disposed of at a Chevron-approved TSDF authorized for hazardous waste disposal (Class I) accompanied by a non-hazardous waste manifest. Non-hazardous waste can also be disposed of in non hazardous landfills (Class II) accompanied by a non hazardous waste manifest. Non hazardous waste should be placed in the appropriate section of the designated storage locations. Non liquid waste may be placed in non hazardous waste bins to be located in the waste accumulation area. A placard listing acceptable non hazardous waste that can be placed in the bin will be affixed to the side of the bin. Liquid waste will be properly containerized (drums, tanks) and placed in the designated portion of the waste accumulation area. Examples of waste generated at the Project Site that may be considered non hazardous include the following. Refer to Table 4-1 for additional waste and specific handling requirements: Non hazardous impacted soils (NHIS); Groundwater sampling equipment and supplies; Absorbent pads and booms; Spent personal protective equipment (PPE); Empty cans and buckets (Per Title 22 CCR 66261.7, a container is considered empty when all pourable waste no longer pours when the container is inverted, and all non pourable wastes are scraped or otherwise removed); High density polyethylene (HDPE) liner; Punctured aerosol cans; Cement and asphalt; and Miscellaneous material contaminated with crude oil, diesel, and lube oil (i.e. concrete, pipe, oily debris). 4.3 UNIVERSAL WASTE Universal Wastes are considered hazardous wastes upon disposal but pose a lower risk to people and the environment. They are exempted from traditional hazardous waste management requirements, provided that management procedures ensure safe handling, recycling, or disposal. In general, Universal Waste should be handled in a manner that prevents the release of the hazard component to the environment and must be recycled or disposed of at a Universal Waste destination facility (facility with a permit to treat, store, or dispose of hazardous waste). Universal Waste cannot be managed with municipal waste. Universal Waste should be properly packaged and clearly marked/labeled based on waste type. Universal Waste should not be stored onsite longer than one year from the date of generation. Examples of waste generated at the Project Site that may be considered Universal Waste include the following. Refer to Table 4-1 for additional waste and specific handling requirements. Batteries (rechargeable Ni Cd batteries, small sealed lead acid batteries, mercury batteries, alkaline batteries); 15 - Chevron San Luis Obispo Tank Farm Remediation and Restoration Project Waste Management Plan Project No. 1301-0304 Lamps (fluorescent tubes and bulbs, sodium vapor lamps); cathode ray tubes (CRT) television and computer monitors); Electronic devices (e waste). E waste may include electronic equipment without CRT such as cell phones, telephones, computer central processing units (CPUs), laptop and desktop monitors with liquid crystal displays (LCD); Non empty aerosol containers (if they contain an ignitable or toxic propellant or contents that exhibit hazardous waste characteristics); and Mercury containing waste (switches, thermostats, switches, thermometers, dilators/tubing, gas flow regulators). 4.4 ASBESTOS CONTAINING MATERIAL Asbestos containing material (ACM) is considered hazardous if it is friable and contains 1.0 percent or more asbestos. Friable waste is one that can be reduced to powder or dust under hand pressure when dry. Although the United States Environmental Protection Agency (USEPA) does not regulate asbestos as hazardous waste under Resource Conservation and Recovery Act (RCRA) it is considered a “non RCRA” or “California only” hazardous waste and is regulated under CCR Title 22, Chapter 11. Non friable ACM is not considered hazardous regardless of asbestos content and is therefore not subject to state regulation. If ACM or suspected ACM is discovered onsite the location should be flagged or staked, and the Project Site Waste Coordinator should be notified for evaluation. Field personnel should not handle or move ACM until it is evaluated by the Project Site Waste Coordinator. Only qualified licensed asbestos abatement contractors will abate and manage ACM in accordance with federal and state regulations and a Project Site Asbestos Management Plan, if necessary. Removed friable ACM waste must be properly contained on leak tight, sealed containers with a caution label affixed to the outside of the container in accordance with CCR Title 8, Section 5208. ACM must be disposed of in a landfill that is authorized to accept asbestos waste. Examples of waste generated at the Project Site that may be considered ACM (friable and non friable) include the following. Refer to Table 4-1 for additional waste and specific handling requirements. Gaskets; Transite pipe; Concrete; Thermal system insulation; and Mastic adhesives (wrapping found around pipes, floor tiles and windows). 16 - Chevron San Luis Obispo Tank Farm Remediation and Restoration Project Waste Management Plan Project No. 1301-0304 4.5 LEAD WASTE Lead containing waste is regulated by both the USEPA under RCRA and California under CCR Title 22, Chapter 11. Lead containing waste is considered RCRA hazardous if by Toxicity Characteristic Leaching Procedure (TCLP) the waste contains 5.0 milligrams per liter mg/L) or greater lead by volume. Lead containing waste may also be considered “California only” hazardous if by chemical analysis either the Total Threshold Limit Concentration (TTLC) and/or Soluble Threshold Limit Concentration (STLC) meets or exceeds 1,000 milligrams per kilograms (mg/kg) or 5.0 mg/L by volume, respectively. If lead containing waste or suspected lead containing waste is discovered onsite, the location or material should be flagged or staked and the Project Site Waste Coordinator should be notified for evaluation. Lead containing waste should be handled so that the disturbance of the material does not cause leaded material to become airborne or spread onto soil. Any suspected lead containing waste should be placed onto plastic sheeting and covered pending analysis and disposal. Lead containing waste must be disposed of at an appropriate facility taking into consideration the concentrations of lead. Refer to Table 4-1 for additional waste and specific handling requirements. Paint; Piping; Batteries; Fluorescent lamps; and Electrical switches. 4.6 RECYCLABLE MATERIAL A recyclable waste is a material or substance that can no longer be used for its original purpose without reclaiming or remanufacturing. Prior to activities requiring waste disposal, the Project Site Waste Coordinator will identify opportunities to recycle and salvage waste generated during remediation and decommissioning activities, and if necessary, develop a Recycling/Solid Waste Handling Plan; thereby minimizing the amount of material requiring disposal. Examples of waste generated at the Project Site that may be considered recyclable material include the following. Refer to Table 4-1 for additional waste and specific handling requirements. Used Tires (regulated by the California Department of Resources Recycling and Recovery (CalRecycle)) Asphaltic concrete (AC); Metal (pipes, drums, sheet pile, etc.); Clean concrete; Office waste (paper, plastic, glass); and Certain waste oils. 17 - Chevron San Luis Obispo Tank Farm Remediation and Restoration Project Waste Management Plan Project No. 1301-0304 The following steps must be followed as part of CEMC’s Scrap Metal Procedures when shipping scrap metal or any other items of value owned by Chevron to a recycler if the item has monetary value. Prior to sending a recyclable bin off site, contents must be reviewed and categorized by a CEMC Project Manager or the CEMC Construction Representative; CEMC Project Manager seeks operational approval via email based on CEMC’s Asset Guidelines; CEMC Construction Representative or CEMC Supplier Employee contacts the North American Waste Desk to order the Bill of Ladings (BOL). The four copies of each individual BOL ticket is utilized to track scrap metal transportation; CEMC Construction Representative or CEMC Supplier completes the Generator’s Section of the BOL, obtains signatures and retains BOL copy #4 prior to scrap departing from the Project Site; Transporter driver retains BOL copies #1, #2 and #3 and is released for departure from the Project Site; Driver provides copy #1 and #2 of the BOL ticket to the recycler along with a copy of the sales agreement; CEMC Construction Representative or CEMC Supplier obtains scrap receipt, weight ticket, funds, BOL copies #1 and #2 from the recycler; CEMC Construction Representative or CEMC Supplier issues an Ariba Credit Memo and uploads BOL #2, weight ticket and receipt; CEMC Project Manager receives Credit Memo in Ariba and approves. Upon approval from Financial Shared Services, a CEMC Financial Analyst will reconcile BOL copy #2; and CEMC Construction Representative or CEMC Supplier enters the BOL information into E-Suites. 4.7 MUNICIPAL WASTE Municipal waste is typically generated in the offices during the course of the work day. Municipal waste is placed in the appropriate “trash” bins and disposed of at a municipal landfill. Recyclable municipal waste, such as paper, plastic and glass are collected in the blue recyclable” bins placed in each office location and handled with the recyclable materials. As mentioned in section 4.3, Universal Waste should not be placed in municipal waste containers. 18 - Chevron San Luis Obispo Tank Farm Remediation and Restoration Project Waste Management Plan Project No. 1301-0304 5.0 WASTE IDENTIFICATION AND PROFILE PREPARATION Most routine wastes generated at the Project Site have been characterized, profiled, managed, and disposed of as non hazardous waste. Ongoing laboratory analysis of routine waste is required for disposal purposes to indicate that the waste has remained consistent and that no regulatory thresholds are exceeded. The frequency and type of laboratory analysis for routine waste streams is dictated by the disposal facility. Disposal and recycling facilities may also require a sample be provided to conduct their own analysis and/or an independent analysis report. If a new waste stream is identified or no current disposal permit is in place for a particular waste stream, sampling and analysis will be necessary to characterize and profile the waste prior to making any disposal arrangements. The following sections outline procedures, equipment, and materials necessary to collect and analyze waste samples in accordance with USEPA protocol Chapter 9, “Test Methods for Evaluating Solid Waste, Physical/Chemical Methods”, SW 846, 3rd Edition USEPA, 1986), and to prepare waste profile sheets for acceptance into a disposal facility. All new waste profiles or re certifications must be reviewed and signed by the CEMC/RBU Environmental Specialist, or designated person, prior to be being submitted to a Chevron approved facility. 5.1 SAMPLE COLLECTION The Project Site Waste Coordinator will perform sample collection or closely coordinate sample collection if done by field personnel. Procedures for sample collection, preservation, and analytical requirements will be developed by the Project Site Waste Coordinator based on the following information: Knowledge about waste stream – previous analysis, SDS Origin of waste – tanks, sumps, drums, bulk or soils Waste stream matrix – liquid, solid, multi phase Disposal facility waste profile and approval requirements 5.1.1 Sample Location The goal of any waste sampling event is to obtain representative samples that allow measurements of the physical and chemical properties of the waste that are both accurate and precise. Samples may be collected as grab samples (discrete sample) or composite samples multiple discrete samples combined into a single sample) based on the disposal facility’s requirements. Sample collection locations and methods will be considered by the Project Site Waste Coordinator during the sample planning phase. 5.1.2 Sample Containers Each laboratory analytical method requires a specific volume of sample material, container type, and in some cases a preservative. Sample bottles can usually be obtained from the laboratory that will be performing the analysis. The laboratory will include the appropriate preservatives in sample bottles as needed based on the parameters being analyzed. The laboratory should be contacted a few days prior to sample collection to allow timely delivery of the proper sample bottles. 19 - Chevron San Luis Obispo Tank Farm Remediation and Restoration Project Waste Management Plan Project No. 1301-0304 5.1.3 Sample Labels Properly completed labels must be affixed to each sample bottle to allow for accurate sample identification and analysis at the laboratory. The labels must be filled out completely, using a water proof pen. At a minimum, information recorded on the sample labels should include sample location (vessel, container, or specific location where the sample was collected), date and time of sample collection, sample type (grab or composite), sample matrix water, soil), sample identification number (unique number for sample tracking purposes), required analysis (list USEPA Method number), and initials of sample collector. Sample labels can usually be obtained from the laboratory that will be performing the analysis. 5.1.4 Chain of Custody A properly completed chain of custody (COC) form must accompany all samples from the Project Site through delivery to the laboratory. At a minimum, the COC form must identify each sample bottle by sample identification number, the sample collector, date and time of sample collection, sample matrix, sample location, preservative (if any), and required analysis. The COC form should be signed by the sampler and every other individual who takes possession of the samples until they are received by laboratory personnel. The person delivering the samples to the laboratory should get a copy of the completed COC form and return it to the Project Site Waste Coordinator for recordkeeping. 5.2 ANALYTICAL REQUIREMENTS Analytical requirements are based on the waste type, matrix, and the disposal facility’s waste approval requirements. Laboratory test methods are assigned a unique USEPA method identification number. To accurately communicate analytical requirements to the laboratory, the proper USEPA Test Method number must be referenced on the COC which must accompany each sample or group of samples. Test Method identification numbers should be reviewed annually at a minimum to ensure the most current method is referenced. Typical USEPA Test Methods required for waste characterization and the corresponding analyte are included in Table 5-1. Please note additional waste characterization analysis may be performed as required by the disposal facility. The Project Site Waste Coordinator will finalize analytical requirements during the sampling planning phase.

Questionable data will be discussed with laboratory Quality Control personnel to determine if sampling and/or laboratory errors have occurred and to determine the proper course of action to rectify discrepancies. 5.4 WASTE PROFILES Each waste stream generated at the Project Site will have a specific waste profile sheet prepared as part of the disposal facility’s approval process. Waste profile sheets will be prepared and signed by the CEMC/RBU Environmental Specialist or Designee. The waste profile sheet is typically provided by the disposal facility destined to receive the waste. Information to be included on the waste profile sheet varies based on the disposal facility’s requirements but typically includes information about the waste generator and waste stream, a description of how the waste is generated, physical and chemical properties of the waste, regulatory status (hazardous, non hazardous, California hazardous), DOT shipping requirements, and applicable LDRs. A copy of the laboratory analytical report is typically included with the waste profile sheet. Once the disposal facility approves the waste profile sheet and analytical data, a waste profile number is assigned to the waste and must be referenced once transport of the waste to the disposal facility begins. Waste profile sheets and disposal facility acceptance are valid for a specific time frame dictated by the disposal facility. Waste profile sheets must be revised and renewed to remain current and in the event there is a change in the waste stream or generation process. The CEMC Construction Representative will be responsible for tracking existing waste profile sheets and approvals as well as updating, renewing, and revising existing waste profile sheets as needed to keep approvals current and valid. 21 - Chevron San Luis Obispo Tank Farm Remediation and Restoration Project Waste Management Plan Project No. 1301-0304 6.0 WASTE STORAGE PROCEDURES Waste storage begins when waste is generated and ends at transportation of the waste offsite for recycling, disposal, or treatment. Storage requirements and location are based on waste characterization. All wastes should be stored and handled in a safe and secure manner that prevents the creation of nuisances (odor, spills, dust, etc.). Before or shortly after placing waste in any storage location or bin, the Project Site Waste Coordinator should be notified. In the event it is not clear where or how waste should be stored, contact the Project Site Waste Coordinator for guidance. The following sections describe specific waste storage procedures and protocols. 6.1 WASTE STORAGE LOCATION Waste storage locations established at the Project Site have been designed according to the type of waste it will contain and whether the waste is bulk or containerized. Bulk waste includes NHIS which is staged in stockpiles prior to loading into transport trucks for offsite disposal. NHIS stockpiles will be placed in a designated stockpile areas (refer to Figure 4-1) constructed in accordance with project specific plans approved by San Luis Obispo County Planning and Building Department and Environmental Health Services, in addition to other applicable agencies with regulatory oversight. Non-hazardous waste such as liquids will be stored in 55-gallon drums (e.g. groundwater), frac tanks, or portable tanks located in the contractor staging area (refer to Figure 4-1). Any tanks will be monitored in accordance with the applicable San Luis Obispo County Air Pollution Control District regulations. Other non-hazardous materials will be stored in the designated waste storage areas within the contractor staging area (refer to Figure 4-1). The bin and containerized waste storage location for hazardous waste is located in the contractor staging area outside of the Runway Protection Zone . Other hazardous wastes such as lead and asbestos containing materials will be stored in designated areas within the contractor staging area (refer to Figure 4-1) or as determined by project specific plans. Lead and asbestos will be sampled and handled by qualified personnel. The Project Site is secured with a locked chain link fence to prevent unauthorized access. Universal waste will be stored in designated bins or drums within the main office or warehouse of the contractor staging area (refer to Figure 4-1). Universal waste will be separated by its classification and the storage bins will be labeled according to the type of waste. Bins will be emptied on a yearly basis, or as needed. Recyclable materials such as scrap pipe, concrete, and asphalt will be stored in designated areas within the contractor staging area (refer to Figure 4-1). Office waste and recyclables will be placed in the designated waste bin located in the buildings. Waste and recyclables will be transferred to the outdoor waste and recycle bins located in the contractor staging area on a regular basis (refer to Figure 4-1). 22 - Chevron San Luis Obispo Tank Farm Remediation and Restoration Project Waste Management Plan Project No. 1301-0304 6.2 SIGNAGE Caution Unauthorized Personnel Keep Out” and “No Smoking” signs will be prominently posted on at the hazardous waste storage location. Signs will be used to designate areas for Universal Waste” and “Non Hazardous Waste” storage locations. Magnetized placards or other signs will be placed on each non hazardous waste bin and recyclable bin to indicate specific waste types that are allowed to be placed in the bins. 6.3 CONTAINERS Waste storage containers may include bulk liquid storage tanks (DT 398, TB 1001, Baker tanks, totes), DOT approved roll off bins, DOT approved drums, plastic totes or tubs, and 5-gallon buckets. Containerized waste (drums, totes, buckets) will be placed in the storage location within the concrete pad area. Roll off bins for non liquid waste will be staged within the designated area in accordance with project plans. After placing containers in the appropriate staging area, the Waste Bin Storage Log (Appendix C and appropriate Storage Site Entry and Waste Placement Log (refer to Appendices D though F) will be filled out. The following procedures should be followed when placing and managing containers in the waste storage location: Containerized waste should be placed in the properly designated area within the storage location; Incompatible waste (ignitable, reactive) should be segregated; Incompatibility will be determined based on waste characterization analysis, SDS, or as directed by the Project Site Waste Coordinator; There should be sufficient space between containers and bins to allow adequate access for inspections; Containers and bins should remain closed during storage except when necessary to add or remove waste; Drums should be placed on pallets or metal grate; and Fill out the proper Storage Site Entry and Waste Placement Log. 6.4 CONTAINER LABELS A properly completed label must be affixed to all containers and bins placed in the storage location. Depending upon the type of the waste stored in the container or bin, the following labels should be used. All container labels must be filled out completely using a water proof pen. Bin labels may be preprinted on magnetized placards. Waste Pending Analysis” – These labels will be affixed to containers of wastes that are awaiting laboratory analysis to determine waste classification. The label will be changed accordingly once the analysis and characterization is complete. The date of sample collection should be noted on the label. Hazardous Waste” – These labels will be affixed to containers of wastes that are known to be hazardous or determined to be hazardous through laboratory analysis. 23 - Chevron San Luis Obispo Tank Farm Remediation and Restoration Project Waste Management Plan Project No. 1301-0304 Hazardous waste labels will be completed in accordance with federal and state regulations. Non hazardous Waste” – These labels will be affixed to containers or bins of wastes that are known to be non hazardous or determined to be non hazardous through laboratory analysis. Universal Waste” – These labels will be affixed to containers, drums or totes for batteries, lamps, electronic devices, and mercury waste. The label should indicate the specific Universal Waste that has been placed in the container. ACM Waste” – Packages or containers holding friable asbestos must have caution labels affixed to the outside in a conspicuous location with the following warning: Danger, Contains Asbestos Fibers, Avoid Creating Dust, Cancer and Lung Disease Hazard”. Once labeled, these containers should be placed in the portion of the storage area designated for hazardous material storage. Recyclable Material” – These labels should be affixed to containers and bins that hold recyclable material. 24 - Chevron San Luis Obispo Tank Farm Remediation and Restoration Project Waste Management Plan Project No. 1301-0304 Empty” – These labels should be affixed to containers that are empty and free of materials. Other means of identification (such as temporary signs) may be acceptable when storing waste in bins or tanks. Additional labels may be required for DOT, or other regulatory compliance. 6.5 ACCUMULATION TIME The allowable waste accumulation time is dependent on the waste characterization and the amount of waste generated in a month. There is no accumulation time limit for non hazardous waste, recyclable material, or municipal waste. Universal Waste should not accumulate or be stored onsite longer than one year from the date of generation. The time limit for hazardous waste storage is 90 days if the site produces more than a 1,000 kilograms (2,200 pounds) per month for all hazardous waste generated onsite (Title 22 CCR 66262.34), or 180 days if the site produces more than 100 kilograms (220 pounds) and less than 1,000 kilograms (2,200 pounds) per month for all hazardous waste generated onsite. The 90- or 180-day storage/accumulation clock begins the first day that accumulation begins in the container. Therefore, the date which the period of accumulation begins must be clearly marked on the storage container or entered on the hazard waste label (see above section) affixed to the container holding hazardous waste or Universal Waste. Although not a regulatory requirement, the date that non hazardous waste is placed in storage should also be noted on the non hazardous waste label. Weekly inspections and records must be completed by the Project Site Waste Coordinator or designee while hazardous waste and Universal Waste is in storage to ensure applicable storage time limits are not exceeded. 6.6 SPILL PREVENTION PROCEDURES Waste material will be stored in a manner that will minimize the potential for spills or releases. Bulk and containerized liquid waste will be stored in areas with secondary containment to capture and contain potential spills or leaks. Bulk and containerized solid waste will be covered when not being added to or actively managed. The areas will be routinely inspected for evidence of spills or releases. The following spill control equipment will be available in or near the waste storage locations, as needed, for quick access and response to potential spills or releases: Sorbent pads and booms; Oil drip pans; Spill kits; and Over pack drums. In addition, a fire extinguisher, eyewash station, and first aid kit will be located near waste storage areas. Equipment will be inspected on a monthly basis, at a minimum. Inspections, maintenance, and corrective actions will be documented on an inspection sheet. 25 - Chevron San Luis Obispo Tank Farm Remediation and Restoration Project Waste Management Plan Project No. 1301-0304 6.7 INSPECTIONS The Project Site Waste Coordinator or trained Project Site field personnel will routinely inspect waste storage locations. Tanks and NHIS stockpile areas are routinely inspected as part of the daily Project Site operations. The waste storage location will be inspected weekly and documented on a Waste Storage Area Container Inspection Record Form included as Appendix A. The Inspection Record Form will be filed and maintained by the Project Site Waste Coordinator or designee. At a minimum, the waste storage location inspections should include the following: Note condition of containers and bins (leaks, spills, corrosion); Ensure containers and bins are closed; Ensure proper and complete labels are affixed to each container and bin; and Ensure accumulation dates are noted on hazardous waste labels and that the accumulation time limits have not been exceeded. Any issues noted on the Inspection Report Form should be immediately reported to the Project Site Waste Coordinator (if not conducting the inspection) and remedied in a timely manner which ensures that the problem does not lead to an environmental or human health hazard. Where a hazard is imminent or has already occurred, remedial action must be taken immediately. 26 - Chevron San Luis Obispo Tank Farm Remediation and Restoration Project Waste Management Plan Project No. 1301-0304 7.0 WASTE TRANSPORTATION Transportation of hazardous, non hazardous, and recyclable waste will only be performed by Chevron approved transporters. Hazardous waste must be transported by a California Registered Hazardous Waste Hauler. Proper paperwork required to accompany each shipment of waste will be completed by the CEMC Construction Representative and signed by the CEMC/RBU Environmental Specialist or Designee. 7.1 APPROVED WASTE TRANSPORTERS Table 7-1 identifies transporters that are approved to haul waste from the Project Site.

An approved signature for any manifest or Bill of Lading will be completed prior to the start of any applicable waste management task. The type of documentation required will include the following: Uniform Hazardous Waste Manifest – accompanies all hazardous waste loads and will be prepared and distributed in accordance with CCR Title 22 66262.20. The Uniform Hazard Waste Manifests are obtained from the State (USEPA Form 8700 22). The CEMC/RBU Environmental Specialist or an authorized designee will prepare and sign the manifest. The manifest must be signed by the transporter upon pickup, the disposal facility upon receipt, and returned to the generator (Project Site) as proof of delivery. 27 - Chevron San Luis Obispo Tank Farm Remediation and Restoration Project Waste Management Plan Project No. 1301-0304 Land Disposal Restriction Form – accompanies all hazardous waste to indicate if a waste requires treatment prior to land disposal to meet LDR thresholds. Non hazardous Waste Manifest – accompanies all non hazardous waste loads. The Non hazardous Waste Manifest may be provided by CEMC/RBU or the disposal facility receiving the waste. Examples of waste requiring a Non hazardous Waste Manifest include; NHIS, Universal Waste, material in non hazardous bins. Bill of Lading – accompanies all recyclable loads. The Bill of Lading may be provided by CEMC/RBU or CEMC Construction Representative. Examples of waste requiring a Bill of Lading include concrete and asphalt. Bill of Lading – is required when shipping scrap metal or any other items of value owned by Chevron to a recycler if the item has monetary value in accordance with CEMC’s Scrap Sale Procedures. 7.3 VEHICLE INSPECTION The Project Site Waste Coordinator or trained field personnel will inspect all vehicles transporting waste material from the Project Site prior to the vehicle exiting the site. The inspection will be documented on the Transporter Inspection Form included as Appendix B. The form will record transporter information (name, truck number, trailer number, DOT number, California number, placard number, driver’s name), the name of the destination disposal/recycling facility, and the manifest or Bill of Lading that accompanies the waste material. The vehicle will also be inspected for leaks, tire lug nuts, and to ensure it is properly covered and secured. The Transporter Inspection Form will be filed and maintained by the Project Site Waste Coordinator. 28 - Chevron San Luis Obispo Tank Farm Remediation and Restoration Project Waste Management Plan Project No. 1301-0304 8.0 WASTE DISPOSAL AND RECYCLING All waste must be disposed of, or recycled, at a Chevron approved Select for Use facility. Hazardous waste must be disposed of in approved Class I permitted disposal facilities. Non hazardous waste must be disposed of in approved Class I or Class II permitted disposal facilities. Municipal waste can be disposed of in an approved Class III permitted disposal facility. 8.1 APPROVED DISPOSAL AND RECYCLING FACILITIES Table 8-1 identifies disposal and recycling facilities that are approved for use for disposal/recycling of waste generated at the Project Site.

The Project Site Waste Coordinator will schedule and coordinate the offsite transportation and disposal, or recycling, of all waste generated at the Project Site with the exception of bulk NHIS. Ongoing transportation of bulk NHIS is scheduled and coordinated by the approved transporter (TBD), and the disposal facility. The Project Site Waste Coordinator responsibilities 29 - Chevron San Luis Obispo Tank Farm Remediation and Restoration Project Waste Management Plan Project No. 1301-0304 related to bulk NHIS transportation and disposal include ensuring the waste profile remains current, manifest tracking, and tracking tons and/or yards of NHIS transported offsite. When remaining waste streams require removal, the Project Site Waste Coordinator will be notified in a timely manner to allow scheduling with the appropriate transporter, disposal, or recycling facility and time to prepare required paperwork and documentation. Work orders may be used to provide information related to the type of waste to be transported offsite, time frame and reason for removal. 30 - Chevron San Luis Obispo Tank Farm Remediation and Restoration Project Waste Management Plan Project No. 1301-0304 9.0 DOCUMENTATION, RECORDKEEPING AND REPORTING Documentation, recordkeeping, and reporting are a critical part of waste management activities and required to fulfill various regulatory requirements and permit condition. The CEMC/RBU Environmental Specialist or designee will have overall responsibility for tracking and maintaining documents and reports pertaining to waste management activities. All documents related to the characterization and disposal of wastes generated at the Project Site will be reviewed and approved by the CEMC/RBU Environmental Specialist or designee prior to submission to the designated disposal facility or any regulatory agency. The Project Site Waste Compliance Group may also be responsible for some recordkeeping and reporting that may be related to permit conditions. The following sections summarize waste management related documentation, recordkeeping and reporting requirements. 9.1 WASTE TRACKING AND REPORTING The Project Site Waste Coordinator will maintain a hazardous/non hazardous waste tracking log to track information related to each type of waste generated and stored onsite. At a minimum, information on the waste tracking log will include the following: Storage location of each bin, tank, or container; Bin, tank, or container number (if applicable), size, and content; Accumulation start date (as shown on the container label); Disposal date; Waste analysis completed and available (yes or no); Labeling information; Waste profile number; and Manifest/Bill of Lading number when material is transported offsite. In addition to above items, the excavation, storage, loading, and offsite transportation and disposal of bulk NHIS is also tracked by the Project Site Waste Coordinator in conjunction with the Project Site Waste Compliance Group and Project Site field personnel (Operations and Maintenance and Construction Groups). The Project Site filed personnel will track the onsite management of bulk NHIS, and the Project Site Waste Coordinator will track offsite transportation and disposal. 9.2 MANIFESTS, BILLS OF LADING, AND LDRS The Project Site Waste Coordinator will track each manifest (hazardous and non hazardous), LDR, and Bill of Lading that is generated. The manifest must be signed by the transporter upon pickup, the disposal facility upon receipt, and returned to the generator (Project Site) as proof of delivery. The Project Site Waste Coordinator will be responsible for cross checking the returned copies and the originals to ensure proof of delivery to the destination facility. Manifests and LDRs will be retained onsite for a minimum of 3 years and 5 years respectively. 31 - Chevron San Luis Obispo Tank Farm Remediation and Restoration Project Waste Management Plan Project No. 1301-0304 Once the final weight tickets or manifests have been received from the landfill, the Project Site Waste Coordinator will be responsible for entering the manifest information into CEMC’s ESS database. The ESS database is used by CEMC to track waste profiles and shipments and quantities for reporting purposes. 9.3 WASTE PROFILES Each waste stream generated at the Project Site will have a waste specific profile sheet prepared as part of the disposal facility’s approval process. Waste profile sheets will be prepared by the CEMC/RBU Environmental Specialist or designee. Waste profile sheets and disposal facility acceptance are valid for a specific time frame dictated by the disposal facility and must be revised and renewed to remain current and in the event the there is a change in the waste stream or generation process. The CEMC/RBU Environmental Specialist or designee will be responsible for tracking existing waste profile sheets and approvals as well as updating, renewing, and revising existing waste profile sheets as needed to keep approvals current and valid. Waste profiles and corresponding analytical reports must be retained onsite for a minimum of 3 years. 9.4 TRAINING RECORDS Records of training required for waste handlers will be maintained onsite. The Project Site Waste Coordinator will ensure training records are current and valid for each waste handler. The Project Site Waste Coordinator will also schedule training sessions in the event additional training is required to accommodate new waste handlers and/or to ensure required training frequencies are met. 9.5 INSPECTION LOGS Results of inspections will be filed and maintained onsite. At a minimum, inspections forms will include the Waste Storage Inspection Record and the Transporter Inspection Form. 32 - Chevron San Luis Obispo Tank Farm Remediation and Restoration Project Waste Management Plan Project No. 1301-0304 10.0 CONTINGENCY SPILL RESPONSE AND REPORTING In the event a waste material is spilled or a waste container leaks, the incident will be promptly reported to the following personnel and cleanup of the spilled material will be performed immediately.

This goal is required by federal law under RCRA and is financially beneficial. Waste minimization also benefits human health, the environment, future liability and public relations. 11.1 WASTE MINIMIZATION TECHNIQUES Waste minimization can be achieved through a wide array of processes that range from simple changes in “housekeeping” practices to the total replacement of production technology. The various types of waste reduction can be ranked in a hierarchy of performance for reducing chemical risk. These include: Chemical substitution (a hazardous chemical substituted by a less hazardous chemical); Product substitution (producing less toxic products or products that are less hazardous to produce); Chemical process changes (changes in production that result in less chemical use or safer chemicals used); Improving production management (through a reduction of spills, leaks, vaporization, etc.); Reclaiming, recycling and reusing chemicals; Point of generation treatment and detoxification; Improving waste management (including improved storage and treatment); and Improve purchasing habits which can reduce non used off spec chemical and paints. Much of the planning necessary to reduce waste requires: Management commitment; Increased awareness and attention to toxic chemicals; Increased motivation to change existing patterns; Knowledge of potential options for change; Willingness to experiment and change; Resources to implement changes; and Willingness to follow through, evaluate and learn from such changes. 11.2 GOOD OPERATING PRACTICES One of the best means of reducing wastes is through better operating or housekeeping practices. Increasing the efficiency of a process can effectively reduce the amounts of waste generated. Better operating practices include finding a more efficient way to handle a particular 34 - Chevron San Luis Obispo Tank Farm Remediation and Restoration Project Waste Management Plan Project No. 1301-0304 waste to a fundamental change in the way we think about waste management. Better operating practices are specific to each waste generating process, but general themes include the following: Personnel Practices Heightened awareness by employees of the need for waste minimization is essential. Training programs, for example, are ways to generate ideas and establish employees’ commitment. Waste Segregation Many wastes are actually mixtures of hazardous and non hazardous waste. Much of their content may even be water. By segregating key toxic constituents, isolating liquid fractions, or keeping hazardous streams from non hazardous waste, can sometimes save substantial amounts of money on disposal or explore opportunities for recycling and reuse. Better Standard Procedures Large quantities of hazardous waste may be generated through spills, improper storage practices, inefficient production start up or shutdown, scheduling problems, lack of emergency procedures and preventive maintenance, or poorly calibrated pollution control devices. New standard procedures manuals, better inventory control and routine training and retraining sessions can help eliminate this inadvertent waste generation and provide significant company wide source reduction benefits.
