The station is situated on the northwest comer of the. intersection of North Oak Street and 24th Street, about 1,650 feet east of State I-Iighway 99. The site location is indicated on Figure 1 - Site Location Map. The facility is an active Texaco service station with a station building and three pump islands. The general layout of the site is shown on Figure 2 - Site Plan. Existing underground storage tanks (LISTs) include three containing gasoline, and one containing diesel. In general, the scope of services provided for this project, as outlined by 'rES, included: soil sampling; vapor monitoring of soil in accordance with the San Joaquin Valley Unified Ak Pollution Control District's (SJVUAPCD) Rule 4651; and, preparation of this report. The purpose of this report is to document closure activities and to present the results of soil sample analyses. This project was conducted under the auspices of the Bakersfield Fire Department, Environmental Services Division. The following services were directly contracted by TES and/or Texaco Refining and Marketing Inc., (TRMI): general contracting services by K.E. Curtis Construction Company, Inc. (K.E. Curtis) of Newbury Park, Califomia; analytical laboratory testing by BC Analytical of Glendale, California; and, soil transportation and disposal services by Belshire Environmental of Lake Forest, California. F:~N'VIX)CS',TEX'~BAKP,.S FL D\TE X-N0 3 3 .P-.PT 2.0 BACKGROUND INFORMATION Review of California and Alaska Oil Field Maps (Munger, 1992), reveals the western portion of the site was once occupied by an uncompleted and abandoned Chevron oil Well described as "Chevron KCL-5, 30-6879, No. 4." Details, descriptions and the exact location of the well were not available as of this writing. Based on information provided by Texaco, the subject service station was originally operated as a Mohawk service station by the Getty Oil Company through early 1985. Fuel from leaking underground storage tanks and piping was first encountered in 1983. Previous investigations and remediation activities at the site included removal of defective leaking fuel underground storage tanks; installation of groundwater monitoring wells; and, the design and installation of a hydrocarbon recovery and treatment system. The recovery system operated into the later months of 1984, when water levels dropped to below the recovery well bottom. The proprietorship of the station was relinquished to Texaco in early 1985. Various phases of remediation were initiated after 1985 as well, by other consulting firms. These included product recovery; in-sim bioremediation; and, carbon adsorption systems for treatment. Analytical data obtained during the prior site activities indicated that contamination existed at the site in both the soil and groundwater. This contamination has been reported as petroleum hydrocarbons as gasoline and diesel, and from volatile aromatic hydrocarbons as benzene, toluene, ethylbenzene and xylenes. Based on information provided by Texaco, no significant contamination was found in any of the groundwater samples from March 1990 through 1993. However, it was noted that impacted soil appeared to remain above the water table. The lead regulatory agency, the Central Valley Regional Water Quality Control Board, granted site closure on December 6, 1994. F:~qVDOC S~TEX~BAKR8 FLD\TE X-N033.1LPT 3.0 GEOLOGIC AND HYDROGEOLOGIC SETTING 3.1 Geology The site area is situated at the southern limits of the San Joaquin Valley, within the Great Valley geomorphic province. The Great Valley is a relatively fiat alluvial plain extending from the Tehachapi Mountains on the south to the Klamath Mountains to the north, and from the Sierra Nevada Mountains on the east to the Coast Ranges on the west. The Great Valley is a downwarped structural trough, deeply infilled with sedimentary rocks. This geosyncline has an asymmetric east-west profile as it rests on a long stable granitic Sierran slope on the east, and valley sediments are steeply upturned on the west (Oakeshott, 1978). The sedimentary sequence of the Great Valley lies unconformably on Paleozoic and Mesozoic metasediments and volcanics, as well as Jurassic and Cretaceous granitic rocks (Hackel, 1966). Sediments within the San Joaquin Valley range from Jurassic to Recent in age. The pre-Quaternary rocks are primarily of marine origin and are composed of siltstone, claystone and sandstone with subordinate volcanics (I-Iackel, 1966). Within the site area, these sediments are estimated to extend to about 10,000 feet below ground surface (bgs). Pleistocene and Recent strata within the San Joaquin Valley are continental in origin, and generally consist of granitic sands and conglomerates (Hackel, 1966). Within the site area, these alluvial sediments were largely deposited by the ancestral Kern River, and were most likely derived from erosion of the Greenhorn Moumains to the east. Earth materials encountered.during site work primarily consist of unconsolidated sands. These sediments are classified as alluvial fan deposits (Smith, 1964). The sedimentary rocks of the San Joaquin Valley have been the source of vast quantities of petroleum and natural gas (Hackel, 1966). Most oil and gas production has been within the central and southern portions of the valley. The San Joaquin Valley has also been the site of major land subsidence. Within the subject portion of the valley, subsidence has primarily occurred south of the Bakersfield area (Poland and Evenson, 1966). Subsidence has been caused by intense pumping of groundwater, resulting in the lowering of the artesian head in deep confined aquifers. F 5ENVDOC S~TEX'~BAKRSFLD\TEX-N033.RPT I I I I I I I ! I I i I I I I I I I I 3.2 Hydrogeology Unconfined groundwater occurs at about 15 feet bgs, as measured in groundwater Monitoring Well MW-8. Monitoring Well lVlW-8 is located in the southern portion of the site, as shown on Figure 2. The Kern River is located approximately 150 feet to the northwest, and is estimatec~to affect the groundwater elevation beneath the site. Local production water is derived from depths of about 250 to 400 feet bgs (Turner, K., personal communication, 1995). Natural groundwater recharge occurs by infiltration of rainwater and infiltration from streams and rivers. Recharge is artificially enhanced via the Cross Valley Channel and the Callaway Weir, which are located north of the site. Additionally, artificial recharge occurs from infiltration of irrigation water. F:~ENVDOC S~TEX~AKRS FLD\TEX-N033.RPT I I I I i I I I I i I I I I I ! I I I 4.0 SUMMARY OF FIELD ACTIVITIES 4.1 Introduction The dispenser replacements were conducted under permit number BI0043, issued by the Bakersfield Fire Department, Hazardous Materials Division, Underground Storage Tank Program, and permit number S-2105-1-4, issued by the San Joaquin Valley Unified Air Pollution Control District (SJVUAPCD). Copies of the permits are included in Exhibit A - Closure Permits. Air quality monitoring during project work was conducted in compliance with the SJVUAPCD Rule 4651. Dispenser replacements were performed by K.E. Curtis, under direct contract with TRMI. ENV America provided oversight services directly for TES and TRMI. 4.2 Dispenser Abandonment and Soil Sampling The fuel dispensers, the pump islands and local surface paving (i.e., concrete) were removed on June 26, 1995. On June 27, 1995, representative soil samples were collected beneath each dispenser. Samples were collected at depths of 2 and 6 feet beneath the piping leading to each dispenser. Identification numbers for samples beneath dispensers remained consistent with the former numerical designation of the dispensers. Each dispenser contained two nozzles which were numbered consecutively 1 and 2, through 15 and 16. For convenience, sample identification refers to the odd numbered nozzle of each dispenser, i.e., sample D1 for nozzles 1 and 2 of the dispenser. With this convention, dispensers D 1 (gasoline), D3 (diesel), and D5 (gasoline) were located on the western pump island; dispensers D7 (gasoline) and D9 (gasoline) were located on the central pump island; and, dispensers D11 (gasoline), D13 (diesel), and D15 (gasoline) were located on the eastern pump island. Dispenser locations are shown on Figure 3 - Partial Site Plan. Samples were collected in glass jars by either of three methods: excavation of a hole by shoveling and direct insertion oftbe glass jar into the soil; by hand-augering a hole and collection of the last augered soil into the glass jar; or by direct insertion of the glass jar into the soil within the bucket of the backhoe. The glass-jar method consisted of placing a pre-cleaned, 4-ounce glass jar into the soil until no headspace remained, and sealing with a threaded, Teflon®-lined lid. Upon collection, each sample was labeled, recorded onto a chain-of-custody form, and submitted directly to an onsite mobile laboratory. Soil sample locations are depicted on Figure 4 - Soil Sample Location Map and Subsurface Profile (Western Pump Island); Figure 5 - Soil Sample Location Map and Subsurface F:~XDC S~TEX~BAKRSFLD\TEX-N033.RPT Profile (Central Pump Island); and Figure 6 - Soil Sample Location Map and Subsurface Profile (Eastern Pump Island). 4.3 Remedial Excavation Upon removal of dispensers and pump islands, and upon review of preliminary analytical data, remedial excavations were initiated. The excavations were performed by means of a backhoe, beneath dispensers where impacted soil was detected. The purpose of additional excavation was to remove as much'impacted soil as reasonably possible without jeopardizing adjacent improvements. The extent of each excavation is shown on Figure 3. The excavation at the western pump island was trapezoidal in plan view with approximate dimensions of 4 feet by 5 feet, and extended to about 5 feet bgs. The excavation at the central pump island was irregular and elongate in plan view, measuring about 6.5 feet by 11 feet and about 10.5 feet deep. The excavation at the eastern pump island was nearly rectangular in plan view, with dimensions of about 5 feet by 7 feet, and about 10.5 feet deep. As soil was excavated, emanating vapors were monitored for volatile organic compounds (VOCs) for health and safety purposes, and to comply with Rule 4561. Air monitoring was conducted utilizing a Photovac HL-2000 organic vapor meter (OVIVl), calibrated to 53 parts per million (,ppm) hexane. Air monitoring records are included in Exhibit B - Ak Monitoring Records. Upon completion of the excavations, post-closure soil samples were collected to document the residual concentrations of petroleum hydrocarbon compounds remaining in-place. Soil sampling and handling were performed in the same manner as beneath the dispensers. Post-closure sample locations are shown on Figures 4, 5, and 6. It is understood that all excavations were subsequently backfilled with imported sand. 4.4 Soil Stockpile All soil excavated from the pump island areas, including the remedial excavations, was placed onsite as one stockpile (SP1). At the end of each day, the stockpile was covered with plastic sheeting. Discrete soil samples were collected from the stockpile for disposal profiling. Sampling was conducted in an identical fashion as described above. Stockpile sample locations are indicated on Figure 7 - Soil Sample Location Map, Soil Stockpile. F:~qVIXX2 SXTEXXBAKRSFLD\TEX-N033.RPT I ! I I I I I I I ,! i I I I I I I I Stockpiled soil was subsequently transported as non-hazardous waste and thermally treated at the TPS Technologies facility in Adelanto, California. Transportation and disposal were performed by Belshire Environmental of Lake Forest, California. Disposal documentation is included in Exhibit C - Non-Hazardous Waste Disposal Records. 4.8 Groundwater Sampling Subsequent to measuring the depth to groundwater in groundwater Monitoring Well MW-8, a groundwater sample was obtained by the TES representative. The sample was collected by lowering a disposable polyethylene bailer into the water colum. The water was slowly decanted into a laboratory-supplied 40 milliliter (mi) glass vial. The sample was submitted to the mobile chemist for transportation to the laboratory. 7 FSENVDOC S~TEX~BAKR.

Soil samples were analyzed for total petroleum hydrocarbons as gasoline (TI>H-G) or as diesel (TPH-D) by USEPA Method 8015M, and for benzene, toluene, ethylbenzene and xylenes (BTEX) per USEPA Method 8020. The groundwater sample was analyzed for TPH by the California Department of Health Services (CADHS) method, and for BTEX per USEPA Method 8020. Selected samples were further analyzed for total lead per USEPA Method 6010. Lead analysis was performed on the sample which contained the highest TPH concentration detected beneath the dispensers, the sample from the stockpile with the highest TPH concentration, and the post-closure samples that exhibited the highest TPH-G and TPH-D concentrations. Analytical results are categorically tabulated in Table 1 - Analytical Results, Dispensers; Table 2 - Analytical Results, Post-Closure Samples; Table 3 - Analytical Results, Soil Stockpile; and Table 4 - Analytical Results, Groundwater Sample. Complete analytical reports are included in Exhibit D - Laboratory Reports and Chain-of-Custody Records. The results are summarized below. 5.2 Western Pump Island (D1, D3, and D5) Initial concentrations (prior to excavation) of TPH-G and TPH-D ranged from non-detectable (<0.5) to 1.1 milligrams per kilogram (rog/kg), and non-detectable (<10) to 11,000 rog/kg, respectively. BTEX concentrations were below laboratory detection limits. After remedial excavation, TPH-G, benzene, ethylbenzene and xylenes were non-detectable. The maximum remnant concentrations of TPH-D and toluene were 63 rog/kg and 0.0051 rog/kg, respectively.

The maximum xylene concentration detected was 78 rag/kg. Benzene, toluene and ethylbenzene were not detected. Remnant lead was detected at a concentration of 49 mg/kg. 5.4 Eastern Pump Island (Dll, D13, and D15) Initial concentrations of TPH-D ranged from 51 to 87,000 rog/kg. Lead was detected at 49 rog/kg. TPH-G and BTEX were not detected. After remedial excavation, the maximum TPH-G and TPH-D concentrations were 790 mg/kg and 17,000 mg/kg, respectively. BTEX and lead concentrations were below the laboratory detection limits. 5.5 Soil Stockpile In samples collected l?om the soil stockpile, maximum TPH-G and TPH-D concentrations were 190 nag/kg and 2,100 nag/kg, respectively. Lead was detected at 7.5 mg/kg. BTEX was not detected. 5.6 Groundwater TPH-G and BTEX concentrations were below the laboratory detection limits in the water sample collected from groundwater Monitoring Well MW-8. 9 F :'~'H VDOCSXTEX~A. KRSFLD\TEX-N033.RY~ I I I I I I I I I I I I i I I I I I I 6.0 CONCLUSIONS AND RECOMMENDATIONS The maximum TPH concentration detected in post-closure samples beneath the western pump island was 63 mg/kg (diesel range). TPH-G or BTEX was not detected. The maximum TPH concentrations detected in post-closure samples beneath the central pump island were 7,500 mg/kg (gasoline range) and 1,200 rog/kg (diesel range). The maximum TPH concentrations detected in post-closure samples beneath the eastern pump island were 17,000 mg/kg (diesel range) and 790 rog/kg (gasoline range). Further site assessment in the vicinity of the central and eastern pump islands is suggested. 10 F:~lqVIX)C~TEXXBAKIt. SFLD~TEX-N 033.Rlrr I I I I I I !

The reproducibility of a procedure demonstrated by the agreement between analyses performed on either dupli- cates of the same sample or a pair of duplicate spikes. A group of twenty samples or less, of similar matrix type, prepped together or analyzed together if no sample preparation is required, under the same conditions and with the same reagents. The batch must include a method blank, LCS and matrix QC. A blank that is spiked with a known amount of analyte and subjected to the same procedures as the samples. The LCS indicates the accuracy of the analytical method. It also serves to double-check the calibration because it is prepared from a different source than the standard used to calibrate the instrument. Quality control performed on actual client samples. The matrix spike is a client's sample spiked with a known amount of analyte. For most analyses, the laboratory performs matrix spikes in duplicate (duplicate spikes). A sample that contains no analyte. For water analysis, organic-free or deionized water is used. For solids analysis, analyte-free solvent is used. The method blank serves to measure contamination associated with laboratory storage, preparation or instrumentation. Numeric designation for a batch of samples and the associated QC. The batch number sequence is unique for each determination. Laboratory result of an LCS analysis. Expected result, or true value, of the LCS analysis. The percentage of analyte recovered. For LCS, the percent recovery calculation is: LC/LT x 100. B C A.~dytic¢d I I I ! ORDER QC REPORT Definitions and Terms Page 2 LC1, LC2 Results of analyzing duplicate LCS's, used to determine precision. RI, R2 Result: Results of analyzing duplicate aliquots of a sample, with R1 indicating the first replicate and R2~the second replicate; used to determine precision. I MS, MSD Result: Results of analyzing a matrix spike and a matrix spike duplicate, used to determine precision. I I I Relative % Diff (RPD): Calculated using one of the following: ~'LCi - LC2~ x 100 ( [LC1 + LC2]/2 ) ! IMS - MSD, x 100 ( [MS + MSD]/2 ) !R1 - R2' X 100 ( [R1 + R2]/2 ) i MS, MSD %: The percentage of analyte recovered in the matrix spikes. The percent recovery calculation is: MS %: (MS - X) x 100 MSD %: (T - X) (MSD - X) x 100 (T - X) where X is the sample result, listed on the analytical report, and T is the true value, defined below. True value: The theoretical, or expected, result of a spiked sample analysis. I NC Flag Q Flag Blank I Result - Indicates that the spike recovery was not calculated due to high sample concentration relative to the amount of spike added.

The reproducibility of a procedure demonstrated by the agreement between analyses performed on either dupli- cates of the same sample or a pair of duplicate spikes. A group of twenty samples or less, of similar matrix type, prepped together or analyzed together if no sample preparation is required, under the same conditions and with the same reagents. The batch must include a method blank, LCS and matrix QC. A blank that is spiked with a known amount of analyte and subjected to the same procedures as the samples. The LCS indicates the accuracy of the analytical method. It also serves to double-check the calibration because it is prepared from a different source than the standard used to calibrate the instrument. Quality control performed on actual client samples. The matrix spike is a client's sample spiked with a known amount of analyte. For most analyses, the laboratory performs matrix spikes in duplicate (duplicate spikes). A sample that contains no analyte. For water analysis, organic-free or deionized water is used. For solids analysis, analyte-free solvent is used. The method blank serves to measure contamination associated with laboratory storage, preparation or instrumentation. Numeric designation for a batch of samples and the associated QC. The batch number sequence is unique for each determination. Laboratory result of an LCS analysis. Expected result, or true value, of the LCS analysis. The percentage of analyte recovered. For LCS, the percent recovery calculation is: LC/LT x 100.

The theoretical, or expected, result of a spiked sample analysis. Indicates that the spike recovery was not calculated due to high sample concentration relative to the amount of spike added. Indicates that the quality control measurement is outside the specified control limits. Laboratory result of analysis of the method blank. BCA-assigned limit, set at a level higher than the method detection limit (MDL) determined using EPA guidelines. Sample RDLs may differ from the blank RDL if the samples were diluted.

A group of twenty samples or less, of similar matrix type, prepped together or analyzed together if no sample preparation is required, under the same conditions and with the same reagents. The batch must include a method blank, LCS and matrix QC. A blank that is spiked with a known amount of analyte and subjected to the same procedures as the samples. The LCS indicates the accuracy of the analytical method. It also serves to double-check the calibration because it is prepared from a different source than the standard used to calibrate the instrument. Quality control performed on actual client samples. The matrix spike is a client's sample spiked with a known amount of analyte. For most analyses, the laboratory performs matrix spikes in duplicate (duplicate spikes). A sample that contains no analyte. For water analysis, organic-free or deionized water is used. For solids analysis, analyte-free solvent is used. The method blank serves to measure contamination associated with laboratory storage, preparation or instrumentation. Numeric designation for a batch of samples and the associated QC. The batch number sequence is unique for each determination. Laboratory result of an LCS analysis. Expected result, or true value, of the LCS analysis. The percentage of analyte recovered.
