(W&A) offers the following information in regards to the UNDERGROUND STORAGE TANK REMOVALS at 1708 Beach Street. The actual address of the property when the tanks were located is 1750 High Street. W&A has previously prepared several documents as outlined in our December 16, 1999 "Status Report", previously delivered. On May 11, 2000, eight samples were procurred from the "stockpiled hydrocarbon impacted soil" on plastic sheeting as outlined on the attached. Samples were procurred from depths of approximately 4 inches and 14 inches at each of the locations and composited, onsite, into one sample from each location. The laboratory then composited samples 1 and 2 into 1 sample and samples 3 and 4 into 1 sample. Each of the two samples were then analyzed for TPA (Diesel) according to 8015M by B.C. Laboratories in Bakersfield. The results are as follows and also attached: Sample TPH No. Dcscr isarl m�=IIc 1 Composite of "1" & "2" 63 2 Composite of "3" & "4" ND 1400 EASTON DR., BUILDING E, SUITE 132 ■ BAKERSFIELD, CA 93309 (661) 325-4862 ■ FAX (661) 325-5126 Ken Thoming 6/2/00 Sandercock Transfer & Storage Co. Page 2 Re: Final Closure Report CONCLUSION Previous reports indicate that; A. Soil samples taken beneath Tank 1 (removed April 14, 1997) were "ND" for TPH. B. Soil samples taken beneath Tank 2 (removed October 12, 1998) contained 111inor amounts of TPH (Diesel), less than 100 mg/kg. C. Soil samples taken from the bioremediated soil indicated that the soil is remediated to less than 63 mg/kg. In our opinion the hydrocarbon impacted soil is remediated sufficient to use on -sits for vehicle maneuvering and parking areas. A copy of this Final Closure Report should be sent to the S.L.O. Planning Department, Attn: Ron Whisenard; Housing Authority of the City of San Luis Obispo, Attn: George J. Maylan; S.L.O. Fire Department, Attn: Molly Brown.

Wilson & Associates, Inc. (W & A) offers the following comments in regards to the underground storage tank removal at 1708 Beach Street. The actual address of the property where the tanks are located is 1750 High Street. Background The facility is located at the northerly intersection of High Street, Beach Street and Church Street in San Luis Obispo. The address of the business is 1708 Beach Street. The business at the site is the office and warehouse for a moving and storage company. The building was constructed in the 1930's as a moving and storage company. It is presumed that the UST's were installed also in the 1930's. At the present time, the current operators have no recollection of the fuel tanks ever being in use at the facility (since 1968). In short, the current operators did not know the UST's were on site until August 1996. The surfacing over the UST's was concrete. Small vent pipes were installed along the northerly edge of the building at 1750 High Street. In August of 1996, Cuesta Geotechnical, Leo Fedewa, were contacted in order to provide consulting services in regards to the "status" of the UST's. In September of 1996, samples were procurred from the liquid in UST's. The tanks apparently contained "water". The samples were delivered toLYMAX laboratories. The results are attached and listed below. Yly tank 20000 mg/kg TPH S'ly tank 1000 mg/kg TPH Approximately 3000 gallons of "water" was removed and transported to a TSD for disposal. In early 1997, the concrete surfacing over the UST's was removed. '. In March of 1997, W & A was contacted to provide consulting services for the UST removal. AQ9I4-7--1E0-9TREET • BAKERSFIELD, CA gaeE - FAX =5J ®2=21-4728 } In March of 1997, B. S. Construction of Bakersfield, California was retained for the purpose of removing what was believed to be at that time a single 3000 - 6000 gallon UST. On April 4, 1997, the City of San Luis Obispo Fire Department issued a permit to B. S. Construction for the removal of "3 - 6000 gallon gasoline tanks" (Copy attached). On or about April 14, 1997 B. S. Construction commenced tank removal operation. It was then very apparent that two UST's were located between the building at 1750 High Street and the northerly property line. One tank being approximately 8 feet in diameter and 20 feet long, while the other tank extended under the fence line located at or near the northerly property by approximately 10 -15 feet. The northerly tank was removed, while the westerly tank as left. Both UST's were extremely thick walled (1/2") steel vessels. On April 16, 1997, John R. Wilson, of W & A, procurred soil samples from; 1. North tank, east end, depth of 3 feet below the bottom of the tank. 2. North tank, west end, depth of 3 feet below the bottom of the tank. 3. #1 stockpile. 4. #2 stock pile. The soil samples were placed in a suitable laboratory container, sealed, labeled, placed in an "ice chest", transported to B. C. Laboratory in Bakersfield, under chain of custody. Due to the unknown use of the UST's, analyses for Oil and Grease, TPH (Gas) and TPH (Diesel) were completed. The results are attached, and are summarized as follows: SAMPLE NUMBERS Constituent 1 2 1 4 CADMIUM (mg/kg) ND ND ND ND CHROMIUM (mg/kg) 66 32 289 351 LEAD (mg/kg) 14 13 20 10 NICKEL (mg/kg) 43 46 442 501 NICKEL (mg/1) - - 4.0 6.1 ZINC (mg/kg) 71 .93 69 63 OIL & GREASE (mg/kg) ND ND 150 40 TPH (Gas) ND ND ND 2.0 TPH (Diesel) ND ND 32 36 As can be seen from the above results, elevated levels of Nickel, Oil & Grease and TPH (Diesel) were detected in the soil samples from both stock piles. The STLC and TTLC levels for Nickel were well below regulatory criteria. The results for TPH (Gas) was considered as not being "elevated". The results from soil samples procurred from beneath the removed tank were non -significant or "non -detect". Southerly UST W & A proposes to remove that portion of the remaining northerly tank lying southerly of the "fence". Due to the close proximity of the structures to the northwest of the tank, it is apparent that the structure stability of the structures could be in question. In addition, electrical and conduits and natural gas line exist over the UST. The following procedure is proposed: Excavate the soil over and around the remaining UST. Remove any liquids in the UST. Place "dry ice" in the UST and wait until a suitable LEL (or equal) reading is attained. A properly trained (Confined Space Certification) person, see attached, would enter the UST and with the aid of proper tools, etc., separate the tank at the fence line into two pieces. The southerly portion of the tank would be removed, soil samples procurred and analyzed, and if deemed satisfactory, the excavation would be backfilled with "clean fill". The remaining portion of the UST lying northerly of the fence would be filled with a "cement slurry" and "abandoned in -place". A large board would be placed over the "open-end" of the tank at the fence line to confine the cement slurry to the remaining portion of the UST. Soil Remediatioii Due to the low levels of hydrocarbon impacted soil, it is proposed to remediate the soil on -site. The proposed procedure is as follows: A portion of site would be cleared and "leveled". "Plastic Sheeting" would be spread over the prepared surface. The excavated and stockpiled soil would be spread over the "plastic sheeting to a depth of less than 2 feet. Water and a high nitrogen fertilizer would be added. The soil would be covered with plastic sheeting and allowed to bio-remediate. At monthly intervals, water and fertilizer would be added, if necessary. At quarterly intervals, samples would be procurred to determine the progress of the bio- remediation. If the results indicate that the TPH levels were less than 25 mg/kg, than the soil would be considered sufficiently remediated. The remediated soil could be used as surfacing for parking and maneuvering areas on site. A. The removal of the entire southerly UST could cause structural problems for the nearby (less than 5') structures. B. The area over the UST is overlain with electrical conduits and natural gas lines. C. The placing of the "cement slurry" in the remaining portion of the UST will bring the tank into an "inert status". Any threats of future structure stability due to the existing tank collapsing caused by the UST deterioration would be negated by the solidifying nature of the cement slurry. D. The testing of the soil under the removed tank will determine if additional excavation or remediation is required. E. The remediation of the slightly hydrocarbon impacted soil, on -site, will allow for recycling the remediated soil on -site as a "paving material". F. The placement of "clean fill" into the excavation will create an environmentally safe site for future users. Please review the above and if you have any questions, please contact this office. If acceptable, a Health and Safety Plan will be added, and submitted to the San Luis Obispo Fire Department for review and approval. Respectfully submitted, WILSON & ASSO IATES, INC.. R.

Re: Status Report 12/16/99 Page 2 of 2 Due to the wet winter of 1997-1998, the site was not dry enough until late summer of 1998 to complete the removal process. On or about September 15, 1998, B.S. Construction commenced the removal process of the remaining UST. The liquid in the tank was removed and the tank was cleaned. See attached WASTE HAULER RECORD. A Marine Chemist inspected the remaining tank on October 8, 1998 and issued a certificate (attached). The remaining tank was subsequently removed to the property line. The remaining portion of the tank was filled with a cement slurry. Soil samples were procurred from the soil at depths of 2' and 6' below the bottom of the removed tank (See below for result summary, results attached). The excavation was backfilled with clean imported soil. A plastic sheeting was placed between the building and the fence and the stockpiled hydrocarbon impacted soil was placed upon the plastic sheeting to a depth of less than 2 feet. Periodically water and high nitrogen fertilizer have been added to facilitate bio-degradation. Surface discing has also been completed.

Sandercock Transfer & Storage Co. 1708 Beach Street San Luis Obispo, Ca. 93401 Re: Underground Storage Tank Removal Permit #28 1708 Beach Street/1750 High Street Dear Ken, The firm of John R. Wilson & Associates, Inc. (W & A) offers the following comments in regards to the underground storage tank removal at 1708 Beach Street. The actual address of the property where the tanks are located is 1750 High Street. Back g,reLiiid The facility is located at the northerly intersection of High Street, Beach Street and Church Street in San Luis Obispo. The address of the business is 1708 Beach Street. The business at the site is the office and warehouse for a moving and storage company. The building was constructed in the 1930's as a moving and storage company. It is presumed that the DST's were installed also in the 1930's. At the present time, the current operators have no recollection of the fuel tanks ever being in use at the facility (since 1968). In short, the current operators did not know the UST's were on site until August 1996. The surfacing over the UST's was concrete. Small vent pipes were installed along the northerly edge of the building at 1750 High Street. In August of 1996, Cuesta Geotechnical, Leo Fedewa, were contacted in order to provide consulting services in regards to the "status" of the UST's. In September of 1996, samples were procurred from the liquid in UST's. The tanks apparently contained "water". The samples were delivered to ZYMAX laboratories. The results are attached and listed below. N' ly tank 20000 mg/kg TPH S' ly tank 1000 mg/kg TPH Approximately 3000 gallons of "water" was removed and transported to a TSD for disposal. In early 1997, the concrete surfacing over the UST's was removed. In March of 1997, W & A was contacted to provide consulting services for the UST removal. 2217 "E" STREET • BAKERSFIELO, CA 93301 (605] 323-6460 • FAX [605] 323-4723 In March of 1997, B. S. Construction of Bakersfield, California was retained for the purpose of removing what was believed to be at that time a single 3000 - 6000 gallon UST. On April 4, 1997, the City of San Luis Obispo Fire__ Department issued a permit to B. S. Construction for the removal of ["3 - 6000 gallon gasoline tanks' (Copy attached). On or about April 14, 1997 B. S. Construction commenced tank removal operation. It was then very apparent that two UST's were located between the building at 1750 High Street and the northerly property line. One tank being approximately 8 feet in diameter and 20 feet long, while the other tank extended under the fence line located at or near the northerly property by approximately 10 -15 feet. The northerly tank was removed, while the westerly tank as left. Both UST's were extremely thick walled (1/2") steel vessels. On April 16, 1997, John R. Wilson, of W & A, procurred soil samples from; 1. North tank, east end, depth of 3 feet below the bottom of the tank. 2. North tank, west end, depth of 3 feet below the bottom of the tank. 3. #1 stockpile. 4. #2 stock pile. The soil samples were placed in a suitable laboratory container, sealed, labeled, placed in an "ice chest", transported to B. C. Laboratory in Bakersfield, under chain of custody. Due to the unknown use of the UST's, analyses for Oil and Grease, TPH (Gas) and TPH (Diesel) were completed. The results are attached, and are summarized as follows: SAMPLE NUMBERS Constitu nt 1 2 3 4 CADMIUM (mg/kg) ND ND ND ND CHROMIUM (mg/kg) 66 32 289 351 LEAD (mg/kg) 14 13 20 10 NICKEL (mg/kg) 43 46 442 501 NICKEL (mg/1) - - 4.0 6.1 ZINC (mg/kg) 71 93 69 63 OIL & GREASE (mg/kg) ND ND 150 40 TPH (Gas) ND ND ND 2.0 TPH (Diesel) ND ND 32 36 As can be seen from the above results, elevated levels of Nickel, Oil & Grease and TPH (Diesel) were detected in the soil samples from both stock piles. The STLC and TTLC levels for Nickel were well below regulatory criteria. The results for TPH (Gas) was considered as not being "elevated". The results from soil samples procurred from beneath the removed tank were non -significant or "non -detect". W & A proposes to remove that portion of the remaining northerly tank lying southerly of the "fence". Due to the close proximity of the structures to the northwest of the tank, it is apparent that the structure stability of the structures could be in question. In addition, electrical and conduits and natural gas line exist over the UST. The following procedure is proposed: Excavate the soil over and around the remaining UST. Remove any liquids in the UST. Place "dry ice" in the UST and wait until a suitable LEL (or equal) reading is attained. A properly trained (Confined Space Certification) person, see attached, would enter the UST and with the aid of proper tools, etc., separate the tank at the fence line into two pieces. The southerly portion of the tank would be removed, soil samples procurred and analyzed, and if deemed satisfactory, the excavation would be backfilled with "clean fill". The remaining portion of the UST lying northerly of the fence would be filled with a "cement slurry" and "abandoned in -place". A large board would be placed over the "open-end" of the tank at the fence line to confine the cement slurry to the remaining portion of the UST. Due to the low levels of hydrocarbon impacted soil, it is proposed to remediate the soil on -site. The proposed procedure is as follows: A portion of site would be cleared and "leveled". "Plastic Sheeting" would be spread over the prepared surface. The excavated and stockpiled soil would be spread over the "plastic sheeting to a depth of less than 2 feet. Water and a high nitrogen fertilizer would be added. The soil would be covered with plastic sheeting and allowed to bio-remediate. At monthly intervals, water and fertilizer would be added, if necessary. At quarterly• intervals, samples would be procurred to determine the progress of the bio- remediation. If the results indicate that the TPH levels were less than 25 mg/kg, than the soil would be considered sufficiently remediated. The remediated soil could be used as surfacing for parking and maneuvering areas on site. A. The removal of the entire southerly UST could cause structural problems for the nearby (less than 5') structures. B. The area over the UST is overlain with electrical conduits and natural gas lines. C. The placing of the "cement slurry" in the remaining portion of the UST will bring the tank into an "inert status". Any threats of future structure stability due to the existing tank collapsing caused by the UST deterioration would be negated by the solidifying nature of the cement slurry. jD. The testing of the soil under the removed tank will determine if additional excavation or remediation is required. E. The remediation of the slightly hydrocarbon impacted soil, on -site, will allow for recycling the remediated soil on -site as a "paving material". F. The placement of "clean fill" into the excavation will create an environmentally safe site for future users. Please review the above and if you have any questions, please contact this office. If acceptable, a Health and Safety Plan will be added, and submitted to the San Luis Obispo Fire Department for review and approval. Respectfully submitted, WILSON & ASSOCIATES, INC. John R.

R. Wilson & Associates, Inc. (W&A) offers the following information in regards to an underground storage tank removal at 1708 Beach Street/1750 High Street, as requested by Leah Stanley of the S.L.O. Fire Department. In March of this year, a single underground storage tank(UST) was removed from the above referenced facility. Another UST is scheduled for removal from the same facility, as described in the attached report. The soil around the UST's is impacted with low levels of hydrocarbon (diesel) impacted soil. The S.L.O. Fire Department has reviewed the attached report and they have issued a "conditional approval" letter, also attached. The condition is "...Prior to any on - site remediation of contaminated soil, the San Luis Obispo City Planning Division must be notified and approval from that department obtained." The attached report details the removal of one of the UST's at the facility. The UST's were located between an existing storage building at the northeasterly property line (see pictures #3, #4, #5, #6, #9, #10 & #11). The removal of the second UST and the on -site remediation of the hydrocarbon impacted soil remains to be completed. The hydrocarbon impacted soil would be excavated from the UST area until the soil is "clean" as verified by laboratory testing. Clean, imported soil would be placed/compacted into the excavation, and the soil surface brought up to the previous existing grade. The surface would be leveled/smoothed with small earth berms constructed at the existing fence lines near the UST site to prevent surface run-on/run-off. Plastic sheeting, 6-mil minimum, would be placed, between the existing building and fence, on the leveled/smoothed ground. The hydrocarbon impacted soil would be placed on the plastic sheeting to a depth of less than 2 feet. Water and a high nitrogen fertilizer would be added to promote the natural bio-degradation of the impacted soil. The soil 2217 'E" STREET • BAKERSFIELO, CA 93301 (e05) 323-6460 • FAX (B05) 323-4723 j would be covered with plastic sheeting to control the moisture content. At monthly intervals, water and fertilizer would be added if necessary. At quarterly intervals the soil would be shallow tilled and soil samples procured to determine the: progress of the bio-degradationtremediation. If laboratory analysis indicate that TPH levels are less than 25mg/kg, then the soil would be considered sufficiently remediated. The remediated soil could be used as surfacing for parking and maneuvering areas on -site. The area set aside for remediation is not visible from surrounding streets and is enclosed with chain link fencing. The volume of impacted soil is estimated at less than 100 cubic yards, and the time estimated for remediation is 6-12 months. Due to the fact that diesel is the hydrocarbon constituent and that the tank has not been used for at least 30 years, the level of any odors will be minimal. Due to the expected wet winter, we will commence the excavation as soon as we get your approval. The report has been submitted to the property owners for their review and approval of the report. If you have any questions please contact this office. Respectfully submitted, WILSON/& ASWC;ATES, INC. 4 R.

Wilson & Associates, Inc. (W&A) offers the following information in regards to the September 22, 1997 correspondence received from the San Luis Obispo Fire Department in regards to the underground tank removal project at your facility. Para 2 The portion of the tank, that is proposed to remain in place will be "certified clean" by the contractor, and verified by W&A, prior to being filled with a "cement slurry" and "abandoned in - place". The tank should test "clean" at the present time, due to our rinsing of the tank during the removal of the northerly tank. The procedure as outlined in our June 20, 1997 report will be followed in order to provide a clean tank. After removal of the southerly portion of the tank, a visual inspection will be made of the remaining portion of the tank and if satisfactory, a letter will be prepared documenting that the remaining portion of the UST is "certified clean'. It is anticipated that the S.L.O. Fire Department will be monitoring the removal and will provide recommendations if applicable. The S.L.O. Planning Division has been notified of the U.S.T. removal and remediation process, and their approval has been requested. Para 3 The Housing Authority should send a letter to the S.L.O. Fire Department stating that they have reviewed the June 20, 1997 report and "approve" of the abandonment in -place of the remaining portion of the UST, subject to the usual testing, documentation, etc. The letter should be requested as soon as possible. 2217 "E" STREET " BAKERSFIELD, CA 93301 (605) 323-6460 • FAX (605) 323-4723 ASLO- =e=_MMWMM Housing Authority of the City of San Luis Obispo LEI MM NOIl,INO M.OIITONITIU 487 Leff Street Post: Office Box 1289 San Luis Obispo CA 93�06-1269 (805) 543-4478 fax (805) 543-4992 Executive Director -Secretary George).

The attached "Site Plan" delineates the position of a "storage building' at 1750 High Street. The storage building is on accessory building for Sandercock Transfer & Storage Co., located immediately to the West at 1708 Beach Street. (See photos #1 & #2). To the rear of the storage building were located two underground storage tanks. The storage tanks (one has been removed) are to be removed, and clean backfill will be placed into the excavation. The remaining hydrocarbon impacted soil, less than 100 c.y. will be placed on 6-mil plastic and allowed to biodegrade with the addition of fertilizer and water over a period of 6 months - 12 months. The pile will be covered with plastic. The pile will be less than 2 feet high, t the conclusion of the biodegradation the soil will be spread as parking area backfill. Attached is a check for the permit fee. If you desire additional information please contact this office. Respectfully submitted, WILSON & ASSOCIATES, INC. John R.
