The purpose of the soil sampling was to fulfill local agency requirements. The services provided by SECOR included the following: · Air monitoring, soil segregation and soil management; *Collecting soil samples following removal of the USTs, product piping, and dispensers as directed by the Bakersfield Fire Department (BFD); ·Oversight during backfill and compaction of the UST excavation and dispenser over-excavation; and * Preparation of this technical report detailing the UST removal and soil sampling activities All site features/buildings, USTs, piping and dispensers associated with ARCO Station 6115 were removed/demolished. The removed USTs and associated piping will not be replaced at this time. SITE INFORMATION The Site is located at the southwest comer of California Avenue and South Chester Avenue in Bakersfield, California (Figures 1 and 2). The Site is located at an elevation of approximately 400 feet above mean sea level (msl). Local topography slopes to the south-southwest at approximately 0.002 feet per foot (USGS, 1954).

(GTI) completed three soil borings (BI through B3) to depths ranging from 20 to 40 feet bgs to evaluate the 'potential presence of petroleum hydrocarbons in soil prior to removal and replacement of the USTs. No detectable concentrations of benzene or total petroleum hydrocarbons characterized as gasoline (TPHg) were identified in any of the soil samples. Low concentrations of toluene (0.009 milligrams per kilogram (mg/kg)) and xylenes (0.027 mg/kg) were detected in boring B2 at 15 feet bgs (B2-15'). Historical soil analytical tables, site maps, and boring logs are included in Appendix A. On September 8, 1993, two 8,000-gallon, and one 6,000-gallon steel gasoline USTs and their associated piping were removed from the site. Soil samples were collected at 2 and 6 feet below the end of each tank and product dispenser. Twelve samples were collected beneath the USTs and 16 samples were collected beneath the dispensers. Elevated concentrations of adsorbed-phase hydrocarbons associated with the USTs were limited to the northern ends of the southern two tanks. Detectable TPHg concentrations ranged from 1.7 mg/kg (T1N-2') to 44,000 mg/kg (T3N-2'). Benzene was detected in only three of the twelve UST samples at concentrations ranging from 0.13 mg/kg (T3-6') to 0.9 mg/kg (T3N-2'). Elevated concentrations of adsorbed-phase hydrocarbons were detected at the westem end of the northern dispenser islands (D3), the western (D5) and eastern (D4) ends of the southern dispenser island, and at the southern end of the eastem dispenser island (D8). Detectable TPHg concentrations ranged from 4 mg/kg (D5-6') to 11,000 mg/kg (D3- 6'). Detectable benzene concentrations ranged from 0.025 mg/kg (D3-2') to 55 mg/kg (D3-6'). On June 9, 1994, SECOR completed three additional soil borings (134 through B6) to assess the vertical and lateral extent of adsorbed-phase hydrocarbons in soil detected during the UST removal. One boring (B4) was completed at the former UST pit, and two angle borings were completed at the western end of the northern dispenser island (B5), and eastern end of the southern dispenser island (B6), respectively. No detectable concentrations of TPHg or BTEX were identified in samples collected from B6, or in samples collected from 40 feet bgs and below from B4 and B5. Detectable concentrations of TPHg ranged from 17 mg/kg (B4-25') to 9,300 mg/kg (B4-15'). Detectable benzene concentrations ranged from 0.035 mg/kg (B4-25') to 5.8 mg/kg (B4-15'). Based on the analytical results from the additional assessment, the BFD issued a no further action letter on March 3, 1995. REGIONAL GEOLOGY AND I-IYDROGEOLOGY The property is located in the southern portion of the San Joaquin Valley, a broad structural trough that forms the southern two-thirds of the Central Valley. The Kern River is located approximately 1.5 miles to the northwest. The local geology consists of Quaternary Age alluvial fan deposits (CDMG, 1965). No active seismic faults are known to have been mapped in the near vicinity (within one mile) of the The closest known faults include unnamed faults located approximately five property. mapped miles to the north and west. The White Wolf Fault is located approximately 14 miles to the southeast and the San Andreas Fault lies approximately 36 miles to the southwest. Underground Storage Tank Removal Report and Request for Site Closure ARCO Station No. 6115 Bakersfield, California Page 3 Groundwater underlying the Bakersfield area is encountered in the Quaternary Age alluvial deposits. Depth to groundwater in the region is noted to be widely variable and seasonal. Approximately 60 percent of the municipal water supply in Kern County is derived from groundwater supplies. According to information provided by the Kern County Water Agency (KCWA), there are approximately 23 municipal wells located within a one-mile radius of the site. The two closest wells are located approximately 200 ft south of the site (No. 62-01), and approximately 1200 feet northwest of the site (No. 3-04). Depth to groundwater for Well No. 62-01 as reported on January 2, 1998, was 195.0 feet bgs. Depth to groundwater for Well No. 3-04 as reported on November 1, 1999, was 162.0 feet bgs. Well locations were plotted on the United States Geological Survey (USGS) 7.5-Minute Oildale and Gosford Quadrangles (USGS, 1954) by Township, Range, Section, and Tract according to data provided by the KCWA. Accuracy of the well locations are limited to the Tracts, which are divided into sixteen ¼ mile by ¼ mile quadrants within each section. Because data was not available for well locations within the Tracts, wells were plotted approximately in the middle of their respective Tract. A figure depicting municipal wells located within a one-mile radius is included with KCWA well data in Appendix B. SITE GEOLOGY AND HYDROGEOLOGY Soil types encountered during previous subsurface investigations consisted primarily of f'me to coarse-grained sand and silty sand, with local silt lenses (SECOR, 1995). Groundwater was not encountered during previous drilling investigations to a maximum depth of 50 feet bgs (SECOR, 1995). EXCAVATED SOIL Excavation activities were performed by Petro Builders, Inc., of Santa Fe Springs, California. The excavated soil was segregated based on volatile organic compound (VOC) concentrations measured using a hand-held photoionization detector (PID). All excavated soil was segregated and stockpiled. To characterize the stockpiled soil, samples were collected from each stockpile and submitted to State-Certified Del Mar Analytical, in Van Nuys, California, for chemical analysis. This section summarizes pertinent information concerning the excavated soil, waste characterization, and final disposition of the excavated soil. For the purposes of this report, soil will be labeled "clean" and "impacted" based on results of chemical analysis. Stockpiles for which results of soil samples are reported to have detectable concentrations are considered "impacted". Analytical results are presented in Table 1. A soil stockpile location map is included with soil disposal documentation in Appendix C.

Product and vapor recovery piping was comprised of double-wall fiberglass. A section of older abandoned single-wall fiberglass product lines were encountered at the western end of the northern dispenser island. The former UST, dispenser and piping locations are presented in Figure 2. SOIL SAMPLING SECOR collected soil samples under the direction of Mr. Steve Underwood, Fire Inspector, BFD Environmental Services. Field activities were conducted in accordance with the procedures for soil sampling included in Appendix F. Soil samples were required at 2 and 6 feet below the product lines and dispensers, and below the end of each UST. The tankpit, product line, and dispenser sample locations are indicated on Figure 2. This section summarizes the results of the soil sampling activities. Lead Agency: BFD Environmental Services Agency Contact Name: Steve Underwood Agency Contact Phone Number: (661) 326-3979 Number of Tank Bottom Samples: 16 Tank Bottom Sample Names: TK-I-14' through TK-8-14', and TK-I-18' through TK-8-18' Number of Piping Samples: 2 Piping Sample Names: PL- 1-3' and PL- 1-6' Number of Dispenser Samples: 12 Dispenser Sample Names: through DS-6-2', DS-l-2' and DS-l-6' through DS-6-6' ANALYTICAL RESULTS All soil collected SECOR to Del Mar (Del Mar) of Van samples by relinquished Analytical were Nuys, California. Del Mar is an ARCO-contracted and California Department of Health Services certified laboratory. SECOR and Del Mar adhered to strict chain-of-custody procedures from Underground Storage Tank Removal Report and Request for Site Closure ARCO Station No. 6115 Bakersfield, California Page 6 sample collection to sample analysis. Soil samples were analyzed for the following analytes and in accordance with the appropriate Environmental Protection Agency (EPA) method: · Total petroleum hydrocarbons as gasoline (TPHg) by EPA Method 8015B; and · Benzene, toluene, ethylbenzene, and xylenes (BTEX), and methyl-tertiary-butyl ether (MTBE) by EPA Method 8021B No detectable concentrations of TPHg, BTEX, or MTBE were identified in any of the soil samples collected beneath the USTs or product lines. Detectable concentrations of TPHg, toluene, ethylbenzene, and total xylenes were identified in samples collected at 2 feet (DS-l-T) and 6 feet (DS-I-6') bgs beneath dispenser DS-1 located at the western end of the northern dispenser island. TPHg concentrations ranged from 710 mg/kg (DS-I-6') to 6,300 mg/kg (DS-I-2'). An additional sample was collected from DS-1 at 9 feet bgs (DS-I-9') which contained only low concentrations of total xylenes (0.019 mg/kg). All other dispenser samples contained non-detectable concentrations of TPHg, BTEX, and MTBE. Soil sample analytical results are summarized in Table 1. Copies of the chain-of-custody documentation and laboratory analytical reports are included in Appendix G. DISPENSER OVER-EXCAVATION AND SOIL SAMPLING On September 14, 1999, the vicinity of former dispenser DS-1 was over-excavated to a depth of 10 feet bgs to remove hydrocarbon-impacted soil identified at 2 (DS-I-2') and 6 (DS-I-6') feet bgs. One sample was collected at 10 feet bgs from the center of the excavation (DS-lA-10'), and four samples were collected at 10 feet bgs from the excavation perimeters (DS-1A-10N, DS-1A-10E, DS-1A-10S, and DS-1A-10W). No detectable concentrations of TPHg, BTEX, or MTBE were identified in any of the soil samples collected from the over-excavation indicating the mass of adsorbed-phase hydrocarbons in soil beneath dispenser DS-1 had been removed. A site map showing the dispenser over-excavation limits and sample locations is presented as Figure 3. BACKFILL/COMPACTION From September 13 through 16, 1999, the UST excavation and dispenser over-excavation pits were backfilled and compacted. BSK of Bakersfield, California, was contracted to provide compaction testing during backfilling. All density tests met or exceeded the minimum required compaction of 90 %. The BSK grading observations and field density tests are included in Appendix H CONCLUSIONS/RECOMMENDATIONS · A total of 183 cubic yards/ 274 tons of soil was excavated during the UST approximately removal activities. Approximately 63 cubic yards/94 tons of "impacted" soil was removed from the site and transported to TPS in Adelanto, California for recycling. Approximately 120 cubic yards/180 tons of "clean" soil was re-used on site as backfill material for the former tankpit excavation. Underground Storage Tank Removal Report and Request for Site Closure ARCO Station No. 6115 Bakersfield, California Page 7 No detectable concentrations of TPHg, BTEX, or MTBE were identified in any of the soil samples collected beneath the USTs or product lines. · Detectable concentrations of TPHg, toluene, ethylbenzene, and total xylenes were identified beneath only one of six dispensers (DS-I). All other dispensers contained non-detectable concentrations of TPHg, BTEX and MTBE. · The vicinity of former DS-1 was over-excavated to a depth of 10 feet bgs to remove hydrocarbon-impacted soil identified at 2 and 6 feet bgs in DS-l-2' and DS-l-6', respectively. No detectable concentrations of TPHg, BTEX, or MTBE were identified in any of the soil samples collected from the over-excavation indicating the mass of adsorbed-phase hydrocarbons in soil beneath dispenser DS-1 had been removed. REQUEST FOR CASE CLOSURE According to the State Water Resources Control Board, a low risk soil site is ready for closure when: 1) the leak has stopped and ongoing sources, including free product, have been removed or remediated; 2) the site has been adequately characterized, and the soil contamination is stable; and 3) no drinking water wells or aquifers, or surface waters have been or are likely to be affected. SECOR considers the case eligible for no further regulatory action on the following basis: · The source of the discharge has been removed and/or repaired. The original USTs, piping, and dispensers were removed and replaced in September 1993. · The newer double-wall fiberglass USTs and piping, dispensers, and all structures associated with ARCO 6115 were removed/demolished in September 1999. · No detectable concentrations of TPHg, BTEX, or MTBE were identified in any of the soil samples collected beneath the fiberglass USTs or product lines. Adsorbed-phase hydrocarbons in soil detected beneath DS-1 were excavated to a depth of 10 feet bgs and removed. No detectable concentrations of TPHg, BTEX, or MTBE were identified in any of the soil samples collected from the over-excavation indicating the mass of adsorbed-phase hydrocarbons in soil beneath dispenser DS-1 had been removed. · Adsorbed-phase hydrocarbons detected during removal of the former steel USTs were limited to the upper 25 feet of the soil column as defined by soil boring B4. Soil borings B1 and B2, completed north and east of the former tankpit, respectively, contained no detectable concentrations of TPHg or BTEX. · Adsorbed-phase hydrocarbons detected below the northern dispenser island during angle- boring installation are limited to approximately the upper 25 to 35 feet of the soil column as defined angle boring B5. Angle boring B6, completed at the eastern end of the southern by dispenser island, contained no detectable concentrations of TPHg or BTEX. Underground Storage Tank Removal Report and Request for Site Closure ARCO Station No. 6115 Bakersfield, California Page 8 · No detectable concentrations of TPHg or BTEX have been identified in soil at or below 40 feet bgs; · At least 122 feet of vadose zone comaining non-detectable concentrations of adsorbed-phase hydrocarbons appears to exist above groundwater (depth to water in Well No. 3-04 last measured at 162 feet bgs on November 1, 1999); Based on the information detailed in this report, SECOR believes that adsorbed-phase hydrocarbons in soil have been fully defined, and that no additional site assessment is required. On behalf of ARCO, SECOR requests that site closure be issued at this site.

All soil I samples were immediately sealed with TeflonTM film, capped, and placed in a chilled cooler for delivery to State-certified Del Mar Analytical of Van Nuys, California for potential chemical analysis. Soil sampling was directed by the associated lead agency representative. SECOP, Iinitiated Chain-of-Custody protocol immediately following the collection of all soil samples. All sampling equipment was cleaned in an aqueous solution of Liqui-NoxTM cleanser or equivalent (no phosphates), rinsed with tap water, and rinsed a second time with deionized water to prevent I cross-contamination between sample intervals.

The site is located at the corner of South Chester and California Avenues in Bakersfield, California (Figures I and 2). The purpose of the assessment is to determine if hydrocarbon contamination exists beneath the tanks, dispensers, or product piping. This report documents regional and site specific geologic settings, assessment procedures and sampling protocol, and contaminant distribution. 2.0 BACKGROUND On August 4, 1993, Groundwater Technology supervised the drilling of three borings (B1 through B3) at the approximate locations shown in Figure 2. Borings B1 and B2 were drilled adjacent to the fill ends of the tanks. B3 was drilled in the center of the proposed new tank location. Total depth of the borings ranged from 20 to 40 feet. Toluene and xylene isomers were detected in sample no. B2-15' at concentrations of 0.009 and 0.027 mg/kg, respectively. No other analytes were detected in the remaining samples which include the deepest sample from each boring. The results of these soil sample analyses are summarized in Table 1. The location of the borings are shown in Figure 2. 3.0 GEOLOGY/HYDROGEOLOGY ARCO facility no. 6115 is located in the central portion of Bakersfield. The approximate elevation of the facility 400 feet above sea level. The site is located, on the alluvial plain of the Kern River. is Topography in the region is essentially flat, and no natural bodies of water adjoin the site. The station is located in a commercial area and is approximately 700 feet east-southeast of the nearest school. The site overlies alluvial-fan deposits of the Kern River (Figure 3). Sediments underlying the region consist of fluvial deposits including silt, sand and gravel. Sediments encountered during drilling activities at the site consist primarily of fine- to coarse-grained sand and silty sand, with local lenses of sandy and clayey silt. I Tank Removal Report ARCO Facility No. 6,,5 []J--~[] GROUNDWATER October 14, 1993 I [~[~-~ TECHNOLOGY I I An unconfined aquifer is present below the site at a depth of approximately 185 feet (Figure 4). In 1991 the gradient of this aquifer was toward the southwest (Figure 5). Shallow, perched water has not been Iidentified in the vicinity of the site (KCWA, 1991). 4.0 EXCAVATION AND TANK REMOVAL ACTIVITIES On September 8, 1993, K. E. Curtis Construction Company excavated soil surrounding existing underground storage tanks at the facility. Tank rinsate was transported, accompanied by a state Uniform Hazardous Waste Manifest, to Gibson Environmental in Bakersfield. A copy of the manifest is presented in Appendix A. After dry ice was placed in the tanks, Mr. Mark Turk of the Bakersfield City Fire Department approved removal of the tanks. Table 2 summarizes tank information details. Upon removal, all tanks were visually inspected to determine their external condition and structural integrity. No holes were found in any of the tanks, but minor rust was observed on each tank. The tanks were removed and loaded onto flatbed trailers for transportation to Golden State Metals in Bakersfield, California for scrapping. A tank disposal form is presented in Appendix A. Following removal of the tanks, soil samples were collected from beneath the bottom of the tanks. On September 9, 1993, soil samples were collected from beneath dispensers at the site. All soil samples were collected following the methodology outlined in Appendix B. 5.0 SOIL SAMPLE ANALYTICAL RESULTS All soil samples collected were submitted to GTEL Environmental Laboratories', Inc. (Certification No. E1075) in Concord, California for chemical analysis. The samples were analyzed for benzene, toluene, ethylbenzene and xylenes (BTEX) and total petroleum hydrocarbons as gasoline (TPHG). Detected concentrations of benzene and TPHG range from 0.025 to 55 mg/kg, and 4 to 44,000 mg/kg, respectively. The highest TPHG concentrations were detected in the sample from beneath the north end of the southernmost tank at a depth of 2 feet (T3N-2'). The highest TPHG concentrations detected in samples from beneath the dispensers, 11,000 mg/kg, was from the 6-foot deep sample under the on (D3-6'). Laboratory results are summarized in Table 3 and in westernmost dispenser the north island Tank Removal Report ARCO Faci,ity No. 6~S [][][] GROUNDWATER October 14, 1993 2 [~[~][~ TECHNOLOGY Figure 6. Specific sampling and analytical procedures are detailed in Appendix B. Complete laboratory reports and chain-of-custody documents are presented in Appendix C. 6.0 SUMMARY The findings of the site assessment activities at ARCO facility no. 6115 can be summarized as follows: · On September 8, 1993, Groundwater Technology witnessed tank removal operations and collected soil samples from beneath the former tanks; · On September 9, 1993, Groundwater Technology collected soil samples from beneath dispensers; · Sediments encountered during excavation and previous assessment work consist primarily of fine- to coarse-grained sand and silty sand, with local lenses of sandy and clayey silt; · An unconfined aquifer is present below the site at a depth of approximately 185 feet. In 1991 the gradient of this aquifer was toward the southwest. Shallow, perched water has not been identified in the vicinity of the site; and · Detected concentrations of benzene and TPHG from and range 0.025 to 55 mg/kg, 4 to 44,000 mg/kg, respectively. The highest TPH concentrations were detected in the sample from beneath the north end of the southernmost tank at a depth of 2 feet (T3N- 2'). The highest TPHG concentrations detected in samples from beneath the dispensers, 11,000 mg/kg, was from the 6-foot deep sample under the westernmost dispenser on the north island (D3-6').

I I I I I I I I I APPENDIX B METHODOLOGY I B.1 Soil Sampling A backhoe was used to retrieve soil samples from beneath the tanks. After overlying soil was removed to the the backhoe bucket retrieved relatively undisturbed soil and brought it to the surface. target depth, At the surface soil samples were then collected by filling a brass sample tube with soil near the digging teeth of the bucket. The sample tube was filled such that no significant headspace was left at either end of the tube. Soil samples were collected from beneath the dispensers using a hand auger and a six-inch sampler. The hand auger was used to drill a slanted boring toward each dispenser from the edge of the island to the desired depth of the sample. A small sampler holding a single, six-inch brass sample tube was then driven into undisturbed soil with a slide hammer and retrieved. £ach sample tube was sealed at each end w~th a teflon sheet, a plastic cap, and tape to secure the plastic cap. lhe samples were labeled to indicate date and time of sample collection, sample location and depth of the sample, prelect location, and the sampler's name. lbo samples were placed on ice in an ice chest pending delivery to an analytical laboratory. B.2 ~bomtor~ Analysis Soil samples were shipped via overnight courier to GIEL Environmental laboratories, Inc. {Certification No. £107§) in Concord, California. lhe temperature within the ice chests was recorded when the samples were received at the laboratory. All soil samples were analyzed for BTEX and TPHG concentrations using EPA methods 8020 and 8015- modified, respectively. Detection .limits for the analytes are generally as follows: · 0.005 mg/kg for BTE; · 0.015 mg/kg for X; and, · 1 mg/kg for TPHG. B.3 Waste Management Excess soil from the excavation operations was sampled, characterized, transported from the site and disposed of at a Class 3 landfill in Arvin, California. A total of approximately 935 yards of soil were transported to the landfill. Non-waste data forms accompanied all transported soil and copies of the forms are presented in Appendix A along with the laboratory reports for characterization and related County correspondence. Sample numbers starting with "SP" indicate soil pile samples.

(GTI) conducted an additional site assessment in June 1994 at ARCO Station #6115 located at 1501 California Avenue in Bakersfield, Califomia. The purpose of the assessment was to further evaluate the lateral and vertical extent of petroleum hydrocarbons previously identified in soil associated with former underground storage tanks. During this assessment, three soil borings (B4, B5, and B6) were drilled and sampled. All work was done in accordance with the work plan prepared by GTI. Responsibility for completing the site assessment activities was subsequently transferred to SECOR Intemational Incorporated (SECOR) as requested by ARCO Products Company. Copies of data generated by GTI were forwarded to SECOR and used in preparation of this report. An unconfmed aquifer is present below the Site at a depth of approximately 200 feet below ground surface. According to 1992 data, the groundwater flow direction has been toward the southwest. Based on the resuks of this and previous assessments, it appears that the lateral and vertical extent of petroleum hydrocarbon constituents in soil have been defined. SECOR, on behalf of ARCO has asked the Bakersfield Fire Department for closure of the site. SECOR Project No. N0600-002-02 6115.rpt I I 1.0 INTRODUCTION I SECOR International Incorporated (SECOR) is pleased to present this report of additional site I assessment activities atthe ARCO Products Company (ARCO) Service Station #6115, located at 1501 California Avenue in Bakersfield, California (Site). Figure 1 is a vicinity map which identifies the location of the Site. The purpose of the additional assessment was to further evaluate the lateral and I vertical extent of petroleum hydrocarbons previously identified in soils beneath the Site. This report summarizes the drilling and sampling activities conducted at the Site by Groundwater Technology, iInc. (GTI) in June, 1994. Copies of previous reports, soil boring logs, analytical reports, and a soil boring location map were provided to SECOR by GTI. SECOR was retained by ARCO to prepare this report based on the information provided by GTI. I 1 1 1 I I 1 I I I I SECOR Project No. N0600-002-02 6115.rpt I 1-! I I 2.0 BACKGROUND INFORMATION I On August 4, 1993, GTI supervised the drilling of three borings (BI through B3) at the approximate I locations shown on Figure 2. The of boring B1 through B3 was to evaluate the potential purpose presence of petroleum hydrocarbons in Site soils prior to the replacement of the underground storage tanks (USTs) at the Site. Borings BI and B2 were drilled adjacent to the fill ends of the USTs. Soil I boring B3 was drilled in the center of the proposed new UST location. Total depth of the borings ranged from 20 to 40 feet below ground surface (bgs). Soil samples collected from 10 and 20 feet I bgs in borings B 1 and B3, and 15 and 40 feet bgs in boring B2 were analyzed for benzene, toluene, ethylbenzene and xylenes (BTEX) and total petroleum hydrocarbons as gasoline (TPHg). I Toluene and xylene isomers were detected in sample B2-15' at concentrations of 0.009 and 0.027 milligrams per kilogram (mg/kg), respectively. No other analytes were detected in the remaining samples analyzed which include the deepest sample from each boring. The results of these soil I summarized in Table 1. sample analyses are i Three USTs and the associated product piping were removed from the Site on September 8, 1993. Soil samples were collected by GTI at depths of two and six feet beneath the bottom of the former USTs and associated dispensers. The samples were analyzed for BTEX and TPHg. Detected concentrations of benzene and TPHg ranged from 0.025 to 55 mg/kg, and 4 to 44,000 mg/kg. respectively. Laboratory analytical results are summarized in Table 2. I In a letter dated April 4, 1994, the Bakersfield Fire Department (Fire Department) requested that further assessment be conducted to define the lateral and vertical extent of the impacted soils associated with the former USTs. The Fire Department also requested that a work plan for further Iassessment be submitted for their review and approval within 30 days of receipt of the letter. A copy of the letter is included as Appendix A. I A work plan dated May 6, 1994 was subsequently submitted to the Fire Department by GTI, on behalf of ARCO. A copy of the work plan is included as Appendix B. The work plan was approved Iby the Fire Department in a letter dated June 1, 1994. A copy of the approval letter is included as Appendix C. All work was done in accordance with the approved work plan. I I I SECOR Project No. N0600-002-02 6115.rpt I 2-1 I 3.0 HYDROGEOLOGY The Site is located in the central portion of Bakersfield, California. The approximate elevation of the I Site is 400 feet above sea level. The Site is located on the alluvial plain of the Kern River. Topography in the region is essentially flat, and no actual bodies of water adjoin the Site. The Site i is located in a commercial area and is approximately 700 feet east-southeast of the nearest school. The Site overlies alluvial-fan deposits of the Kern River. Sediments underlying the region consist Iof fluvial deposits including silt, sand, and gravel. Sediments encountered during drilling activities at the Site by GTI consist primarily of fmc- to coarse-grained sand and silty sand, with local lenses of silt. I An unconfined aquifer is present below the Site at a depth of approximately 200 feet bgs based on information published in the Kern County Water Agency's Water Supply Report 1992, dated December 1993 (KCWA Report). In 1992, the gradient of this aquifer was reported to be toward the southwest. Shallow, perched water has not been identified in the vicinity of the Site based on the iKCWA Report. I SECOR Project No. N0600-002-02 6115.rpt 4.0 SITE ASSESSMENT METHODS 4.1 SOIL BORINGS AND SOIL SAMPLING On June 29, 1994, three soil borings identified as B4, B5, and B6 were advanced by GTI at the locations identified on Figure 2. The purpose of the borings were to further assess the lateral and vertical extent of petroleum hydrocarbons in soils in the areas of the former USTs and dispensers. Soil boring B4 Was advanced to a depth of approximately 45 feet bgs in the area of the former USTs. Soil borings B5 and B6 were advanced at an angle of approximately 30 degrees from vertical to depths of approximately 49 feet and 29 feet bgs respectively in the dispenser area. Soil samples were collected at five foot intervals in each boring. Soil sampling procedures are presented in GTI's work plan included as Appendix B to this report. Soil samples were reportedly screened in the field using a photoionization detector (PID). Copies of the boring logs are included as Appendix D. ,YECOR Project No. N0600-002-02 6115.rpt 4-1 5,0 LABORATORY ANALYSIS Soil sample analyses were conducted at GTEL Environmental Laboratories, Inc. (GTEL) in Concord, California. GTEL is certified by the California Department of Health Services to perform the requested analyses. A total of ten soil samples from borings B4 through B6 were selected for laboratory analysis. The samples were analyzed in the laboratory for TPHg by modified EPA Method 8015 and BTEX by EPA Method 8020. Analytical results from this assessment are presented in Table 1. Copies of the analytical reports and chain-of-custody document are included as Appendix E. SECOR Project No. N0600-002-02 6 l 15.rpt 5-1 I I 6.0 ASSESSMENT RESULTS I 6.1 FIELD RESULTS I The soils type encountered during drilling was mostly sand, with two silt interbeds in boring B5 at the 0 to 6-feet and 36 to 46-feet bgs intervals. The sand varied in grain size from very fine- to fine- I grained, with occasional medium to coarse-grained fractions. Groundwater was not encountered in borings B4, B5 or B6. ! 6.2 LABORATORY RESULTS I Analysis results for soil samples analyzed from each boring are summarized in Table 1 and described below. Copies of individual laboratory analysis reports are included as Appendix E. ! In the following discussions of laboratory results, soil samples are identified by the soil boring number and depth collected bgs. For example, soil sample B6-29 was collected from soil boring B6 I at a depth of 29 feet bgs. I Detectable concentrations of TPHg and/or BTEX were reported in four of the 10 soil samples collected and analyzed. No detectable concentrations of TPHg or BTEX were reported in soil samples collected from soil boring B6. In soil borings B4 and B5, detectable concentrations of TPHg I ranged from a minimum of 17 mg/kg to maximum of 9,300 mg/kg. Detectable concentrations of benzene ranged from a minimum of 0.035 mg/kg to a maximum of 5.8 mg/kg. TPHg and BTEX concentrations with depth, for each soil boring, are presented on Figure 3. I I I I I ! SECOR Projeet No. N0600-002~02 6115.rpt I 6-! 1 I 7.0 RISK ANALYSIS I The estimated action level criteria presented below are established in Table 2-1, Leaching Potential I Analysis for Gasoline and Diesel, Leaking Underground Fuel Tank (LUFT) Manual, State of California Leaking Underground Fuel Tank Task Force, October 1989. I Benzene - 1 mg/kg Toluene - 50 mg/kg Ethylbenzene - 50 mg/kg Xylenes - 50 mg/kg TPH as gasoline - 1,000 mg/kg I The intent of the leaching potential analysis is to estimate concentrations of TPH and BTEX that may be left in place without potentially threatening groundwater quality. The Luft Manual criterion is Iincluded as an alternative soil cleanup level only. We understand that the final soil cleanup levels, if required, will be determined by the Fire Department. A copy of Table 2-1 is included as Appendix I Total petroleum hydrocarbons and BTEX were detected in soil samples analyzed from soil borings I B4 and B5. The concentrations of TPHg and BTEX detected in only the uppermost soil samples collected from soil borings B4 and B5 (15' and 14' bgs, respectively) were above their respective estimated action levels based on criteria established in the LUFT Manual. Total petroleum I hydrocarbons and BTEX concentrations in all other soil samples analyzed, including the samples collected from each boring at their respective total depths, were either below their respective LUFT Manual action levels or not detected above their respective detection limits. I I I 1 I SECOR Project No. N0600-002-02 6115.rpt I7-1 I 8.0 SUMMARY OF FINDINGS Presented below is a summary of findings based on the results of this and previous assessments: No detectable concentrations of TPHg and BTEX were reported in soil samples analyzed from soil borings BI, B2, B3, and B6. Detectable concentrations of TPHg, from soil borings B4 and B5, ranged from a minimum of 17 mg/kg to maximum of 9,300 mg/kg.. Detectable concentrations of benzene ranged from a minimum of 0.035 mg/kg to a maximum of 5.8 mg/kg. The concentrations of petroleum hydrocarbons detected in the soil samples analyzed appear to indicate that a limited quantity of affected soil, above the estimated action levels, remain in place near the former UST area and the northem dispenser area. The vertical extent of affected soils remaining in place near the former UST area appears to be limited to a maximum depth of approximately 25 feet bgs. The lateral extent of affected soils appears to be limited to the southeast comer of the former UST area (near boring B4). The vertical extent of affeCted soils remaining in place near the northem dispenser area appears to be limited to a maximum depth of 24 feet bgs. The lateral extent of appears to limited to westem of northem dispenser (near affected soils be the end the boring BS). Regional depth to groundwater in the Site area is reported to be approximately 200 feet bgs. On the basis of a review of concentrations and depths of detection for petroleum hydrocarbons, the soil types encountered, the regional depth to groundwater, and LUFT Manual guidelines, it that no significant threat to the groundwater appears exists in the areas sampled. I ! SECOR Project No. N0600-002-02 6115.rpt I 8-I 9.0 RECOMMENDATIONS On the basis of the findings presented in this Report, SECOR recommends that no further action be required for the Site. This recommendation is based on the concentrations of petroleum hydrocarbons remaining in place, the limited volume of impacted soil remaining in place, the depth to underlying groundwater, and the surface conditions limiting the potential for vertical migration (i.e. asphaltic concrete or concrete cover over the entire Site). On behalf of ARCO, SECOR requests that if the Fire Department is in agreement with our recommendation, a closure letter be issued to ARCO.

SITE SAFE-FY PLAN m A ssessment Work Plan ARCO Facility No. 5115 mMay 6,1994 I 1.0 INTRODUCTION Groundwater Technology, Inc. has been contracted ARCO Products by Company to conduct assessment activities at their facility no. 6115. The site is located at 1501 California Avenue in Bakersfield (Figures 1 and 2). The purpose of the assessment is to determine the extent of hydrocarbons in soil in the vicinity of the former tanks as requested by the City of Bakersfield (letter of April 4, 1994). This work plan outlines site background, proposed assessment procedures, sampling protocol, and worker safety considerations. Field work methodology is outlined in Appendix A. A site- specific safety plan is presented in Appendix B. 2.0 BACKGROUND I On August 4, 1993, Groundwater Technology supervised the drilling of three borings (B1 through B3) at the approximate locations shown in Figure 2. Borings 81 and B2 were drilled adjacent to the fill ends of Ithe tanks. B3 was drilled in the center of the proposed new tank location. Total depth of the borings ranged from 20 to 40 feet. I Toluene and x'~lene isomers were detected in sample no. B2-15' at concentrations of 0.009 and 0.027 mg/kg, respectively. No other analytes were detected in the remaining samples which include the I deepest sample from each boring. The results of these soil sample analyses are summarized in Table 1. The underground storage tanks were removed on September 8, 1993. Soil samples were collected at depths of 2 and 6 feet from beneath the bottom of the tanks and dispensers. The samples were analyzed for benzene, toluene, ethylbenzene and xylenes (BTEX) and total petroleum hydrocarbons as gasoline (TPHG). Detected concentrations of benzene and TPHG ranged from 0.025 to 55 mg/kg, and 4 to 44,000 mg/kg, respectively. Laboratory results are summarized in Table 2 and in Figure 2. 3.0 GEOLOGY/HYDROGEOLOGY ARCO facility no. 6115 is located in the central portion of Bakersfield. The approximate elevation of the facility is 400 feet above sea level. The site is located on the alluvial plain of the Kern River. Topography in the region is essentially fiat, and no natural bodies of water adjoin the site. The station is located in a commercial area and is approximately 700 feet east-southeast of the nearest school. Assessment Work P~an ARCO Fac;lity NO, 5115 May 6. 3~-~4 1 The site overlies alluvial-fan deposits of the Kern River (Figure 3). Sediments underlying the region consist of fluvial deposits including silt, sand and gravel. Sediments encountered during drilling activities at the site consist primarily of fine- to coarse-grained sand and silty sand, with local lenses of sandy and clayey silt. An unconfined aquifer is present below the site at a depth of approximately 185 feet (Figure 4). In 1991 the gradient of this aquifer was toward the southwest (Figure 5). Shallow, perched water has not been identified in the vicinity of the site (KCWA, 1991). 4.0 PROPOSED SITE ASSESSMENT A preliminary evaluation of the site using the leaching potential analysis developed by the State Water Resources Control Board indicates concentrations of gasoline hydrocarbons below 1000 mg/kg will not pose a threat to groundwater (Table 3; LUFT, 1989). Groundwater Technology proposes drilling borings at the three locations at the site where this screening concentration is exceeded in the deepest sample collected (Figure 2). The borings will be advanced until 10 feet of uncontaminated soil is encountered as evidenced by field screening with a photoionization detector. The purpose of the borings is to determine the vertical extent of gasoline hydrocarbons at these locations. Samples will be collected at 5-foot depth increments. A minimum of three samples collected from each boring will be submitted to a state-certified laboratory for analysis of TPHG and BTEX. Specific sampling, boring abandonment, and waste-handling procedures are discussed in detail in Appendix A.

CHESTE;~ DES. DEL DATE: 5 BAKERSFIELD, CALIFORNIA JDP JDP 8/93 I I APPENDIX A I METHODOLOGY A.1 SOIL BORINGS The drilling rig used for the assessment will be a truck-mounted, hollow-stem auger rig. The borings will be drilled using a 7-inch O.D. auger. Samples will be collected from the borings as described in Section A.2. tf contamination is suspected, the borings will be filled with a 5-sack sand/cement slurry. If no indication of contamination is encountered, the borings will be backfilled with the drill cuttings. The surface will be patched with asphaltic concrete. A.2 SOIL SAMPLING Soil samples will be collected at 5-foot intervals with a split-spoon sampler. The sampler will be fitted with stainless steel or brass sample rings. When the filled sampler is retrieved, the ring to be submitted for analysis will be separated from the other rings with a knife and sealed in such a way that no significant headspace is left at either end of the ring. The ring will be sealed at each end with a teflon sheet, a plastic cap, and tape to secure the plastic cap. The samples will be labeled to indicate date and time of sample collection, boring number and depth of the sample. The sample will be placed on ice in an ice chest pending delivery to an analytical laboratory. Another sample ring retrieved from the sampler will be field screened with a PID for volatile organic compound (VOC) emissions. To do this approximately 2/3 of the material in the sample ring will be removed and the .ring will be capped on both ends with a plastic cap. The ring will then be shaken vigorousiy for several seconds and the inlet to the PID will be inserted into a small hole in one of the caps. The PID reading will be recorded on the drilling log for that sample interval. The material from the second sample ring will be described on the drilling log of the boring using visual classification according to the Unified Soil Classification System. Color, grain size, and sorting charts will be used to aid in the soil classification. Between sampling events, the sampling equipment will be cleaned using a three-bucket wash system. In this system, the rings and samplers are scrubbed in a bucket of detergent, rinsed in a second bucket of tap water and given a final rinse in a bucket of distilled water. A.3 LABORATORY ANALYSIS A minimum of three samples collected from each boring will be submitted for analysis. The selected samples will include the two exhibiting the highest PID readings and the deepest from each boring. The samples will be shipped by overnight courier to a state certified laboratory. All soil samples will be extracted Assessment Work Plan ARCO Fac:lit/No. 6115 May 6. ~994 A1 using EPA method 5030 and analy~ed for BTEX and TPHG concentrations using EPA methods 8020 and 8015-modified, respectively. Detection limits for the analytes will be as follows: · 0.005 mg/kg for BTE; · 0.015 mg/kg for X; · 10 mg/kg for TPHG. A.4 WASTE MANAGEMENT Drill cuttings will be stored on site in appropriately labeled, 55-gallon, D.O.T. approved (17E) drums pending receipt of the analytical results. The lids of the drums will be bolted closed and the drums will be stored in one place at the site. Once the analytical results are received the drum contents will be disposed of by ARCO in an appropriate and timely manner. If contamination is encountered, the drilling augers will be steam-cleaned upon completion of drilling activities. Rinsate from the cleaning operations will be collected in appropriately labeled drums (as above) and disposed of by ARCO following laboratory analysis.

Organic vapor concentrations are monitored in the field with a flame ionization detector (FID) or photoionization detector (PID). All readings are taken in the workers' breathing zone to determine whether an action level has been met and/or exceeded. Air monitoring results must be documented on the Vapor Monitoring Form (Appendix B-3). Air monitoring action leveis (Tabie 3-1) have been developed by Groundwater Technology to indicate the chemical concentrations in the breathing zone that require an upgrade in level of personal protective equipment (PPE). The action levels apply to all tasks performed on this site. Guidelines for frequency of air monitoring are presented in Table 3-2. TABLE 3-1. . Instrument* ' ,. on.. Measureme t Action.

Assessment Work Plan ~ ARCO Facility No. 6115 I~r~IC~ROLTNDW^TER I May 6, 1994 ii II IL_il II TECHNOLOGY I 1.0 INTRODUCTION I Groundwater Technology, Inc. has been contracted by ARCO Products Company to conduct i assessment activities at their facility no. 6115. The site is located at 1501 California Avenue in Bakersfield (Figures 1 and 2). The purpose of the assessment is to determine the extent of hydrocarbons in soil in the vicinity of the former tanks as requested by the City of Bakersfield (letter of I April 4, 1994). This work plan outlines site background, proposed assessment procedures, sampling protocol, and worker safety considerations. Field work methodology is outlined in Appendix A. A site- Ispecific safety plan is presented in Appendix B. I 2.0 BACKGROUND I On August 4, 1993, Groundwater Technology supervised the drilling of three borings (B1 through B3) at i the approximate locations shown in Figure 2. Borings B1 and B2 were drilled adjacent to the fill ends of the tanks. B3 was drilled in the center of the proposed new tank location. Total depth of the borings ranged from 20 to 40 feet. Toluene and xylene isomers.were detected in sample no. B2-15' at concentrations of 0.009 and 0.027 Img/kg, respectively. No other analytes were detected in the remaining samples which include the deepest sample from each boring. The results of these soil sample analyses are summarized in Table 1. I The underground storage tanks were removed on September 8, 1993. Soil samples were collected at idepths of 2 and 6 feet from beneath the bottom of the tanks and dispensers. The samples were analyzed for benzene, toluene, ethylbenzene and xylenes (BTEX) and total petroleum hydrocarbons as gasoline (TPHG). Detected concen{rations of benzene and TPHG ranged from 0.025 to 55 mg/kg, and I 4 to 44,000 mg/kg, respectively. Laboratory results are summarized in Table 2 and in Figure 2. I 3.0 GEOLOGY/HYDROGEOLOGY I ARCO facility no. 6115 is located in the central portion of Bakersfield. The approximate elevation of the I facility is 400 feet above sea level. The site is located on the alluvial plain of the Kern River. Topography in the region is essentially flat, and no natural bodies of water adjoin the site. The station is i located in a commercial area and is approximately 700 feet east-southeast of the nearest school. Assessment Work Plan ARCO Faci,ity No. 6115 [][~]~ CROUNDWATER The site overlies alluvial-fan deposits of the Kern River (Figure 3). Sediments underlying the region consist of fluvial deposits including silt, sand and gravel. Sediments encountered during drilling activities at the site consist primarily of fine- to coarse-grained sand and silty sand, with local lenses of sandy and clayey silt. An unconfined aquifer is present below the site at a depth of approximately 185 feet (Figure 4). In 1991 the gradient of this aquifer was toward the southwest (Figure 5). Shallow, perched water has not been identified in the vicinity of the site (KCWA, 1991). 4.0 PROPOSED SITE ASSESSMENT A preliminary evaluation of the site using the leaching potential analysis developed by the State Water Resources Control Board indicates concentrations of gasoline hydrocarbons below 1000 mg/kg will not pose a threat to groundwater (Table 3; LUFT, 1989). Groundwater Technology proposes drilling borings at the three locations at the site where this screening concentration is exceeded in the deepest sample collected (Figure 2). The borings will be advanced until 10 feet of uncontaminated soil is encountered as evidenced by field sCreening with a photoionization detector. The purpose of the borings is to determine the vertical extent of gasoline hydrocarbons at these locations. Samples will be collected at 5-foot depth increments. A minimum of three samples collected from each boring will be submitted to a state-certified laboratory for analysis of TPHG and BTEX. Specific sampling, boring abandonment, and waste-handling procedures are discussed in detail in Appendix A.

[~[~][~ TECHNOLOGY A. 1 SOIL BORINGS The drilling rig used for the assessment will be a truck-mounted, hollow-stem auger rig. The borings will be drilled using a 7-inch O.D. auger. Samples will be collected from the borings as described in Section A.2. If contamination is suspected, the borings will be filled with a 5-sack sand/cement slurry. If no indication of contamination is encountered, the borings will be backfilled with the drill cuttings. The surface will be patched with asphaltic concrete. A.2 SOIL SAMPLING Soil samples will be collected at 5-foot intervals with a split-spoon sampler. The sampler will be fitted with stainless steel or brass sample rings. When the filled sampler is retrieved, the ring to be submittec~ for analysis will be separated from the other rings with a knife and sealed in such a way that no significant headspace is left at either end of the ring. The ring will be sealed at each end with a teflon' sheet, a plastic cap, and tape to secure the plastic cap. The samples will be labeled to indicate date and time of sample collection, boring, number depth of the sample. The sample will be placed on ice in an ice chest pending delivery to an analytical laboratory. Another sample ring retrieved from the sampler will be field screened with a PID for volatile organic compound (VOC) emissions. To do this approximately 2/3 of the material in the sample ring will be removed and the ring will be capped on both ends with a plastic cap. The ring will then be shaken vigorously for several seconds and the inlet to the PiD will be inserted into a small hole in one of the caps. The PID reading will be recorded on the drilling log for that sample interval. IThe material from the second sample ring will be described on the drilling log of the boring using visual classification according to the unified Soil Classification System. Color, grain size, and sorting charts Iwill be used to aid in the soil classification. Between sampling events, the sampling equipment will be cleaned using a three-bucket wash system. In this system, the rings and samplers are scrubbed in a bucket of detergent, rinsed in a second bucket of tap water and given a final rinse in a bucket of distilled water. A.3 LABORATORY ANALYSIS A minimum of three samples collected from each boring will be submitted for analysis. The selected samples will include the two exhibiting the highest PID readings and the deepest from each boring. The samples will be shipped by overnight courier to a state certified laboratory. All soil samples will be extracted ! Assessment Work Plan ARoo Fac,,,.y .o.

Detection limits for the analytes will be as follows: · 0.005 mg/kg for BTE; · 0.015 mg/kg for X; · 10 mg/kg for TPHG. A.4 WASTE MANAGEMENT Drill cuttings will be stored on site in appropriately labeled, 55-gallon, D.O.T. approved (17E) drums pending receipt of the analytical results. The lids of the drums will be bolted closed and the drums will be stored in one place at the site. Once the analytical results are received the drum contents will be disposed of by ARCO in an appropriate and timely manner. 'If contamination is encountered, the drilling augers will be steam-cleaned upon completion of drilling activities. Rinsate from the cleaning operations will be collected in appropriately labeled drums (as above) and disposed of by ARCO following laboratory, analysis.
