Mr. Craig Perkins County of Los Angeles Department of Public Works February 25, 2010 Page 6 GEOLOGY AND HYDROGEOLOGY The geologic conditions in the site vicinity are characterized from alluvial deposits, underlain by marine and non- marine sedimentary units, metamorphic rocks and crystalline basement material. Surface and near - surface conditions as designated by the U.S. Geological Survey are older alluvium, deposited in northwest - dipping alluvial fans resulting from outwash from the Sierra Nevada mountain range to the east. This alluvium is composed primarily of poorly graded and unconsolidated sands, sandy gravels and occasional discontinuous lenticular bodies of sandy clay and silt. Regionally, the surface ofthese old alluvial fans is undulatory, with a distinct dip toward the Kern River to the northwest of the site. The site itself is located along one of the crests of the alluvial fan surface "ripples" at an elevation of approximately 363 feet above mean sea level (amsl). The total thickness of the alluvial fan deposits is estimated to range from approximately 600 feet west of the site to over 4,000 feet near the Sierra Nevada Mountains. The site lies within the Edison hydrogeologic sub -area of the Edison Maricopa area. Uppermost groundwater within this area occurs within the old alluvial fan deposits. In the site vicinity, deeper aquifers of limited areal extent are present in the consolidated non - marine sedimentary units and within fracture zones of the crystalline basement rock. The most prominent subsurface features controlling the groundwater flow direction are the groundwater barriers formed by the northwest to southwest trending Edison Fault and sub - parallel splays of this fault, located south and north of the site, respectively (WGR, 2003b). Depth to water in the vicinity of the subject site was approximately 140 feet below ground surface (bgs) in February 2009, according to California Water Service records. SITE SPECIFIC GEOLOGY AND HYDROGEOLOGY Soils encountered during site assessment activities consisted primarily of fine to medium grained sands with inter - bedded silty sands to the total depth explored of 100 bgs. Additionally, a sandy to silty clay layer was encountered at approximately 12 feet bgs and inter - bedded fine to coarse grained sands were encountered from approximately 55 feet bgs to approximately 90 feet bgs. WATER WELL SURVEY The nearest surface water body is the Arvin Edison Canal, which is field- verified to be approximately 790 feet east of the site. The Buena Vista Lake Bed is located approximately 1,020 feet northeast of the site. The nearest well (CBK 14) is approximately 3,800 feet southwest of the site; it was measured from 01/1989 through 02/2009 and has an average groundwater elevation of 179 feet bgs. Well CBK 16 is located approximately 4,000 feet south of the site; it was measured from 04/1989 through 02/2009 and has an average groundwater elevation of 185 feet bgs. Well CBK 30 is located 4,200 feet southeast of the site; it was measured from 05/1995 through 02/2009 and has an average groundwater elevation of 191 feet bgs. SUBSURFACE INVESTIGATION PRE -FIELD ACTIVITIES DELTA visited the site to mark the boring and, well locations, contacted Underground Services Alert at least 48 hours prior to drilling, and arranged the drilling schedule. A site - specific health and safety plan was Mr. Craig Perkins County of Los Angeles Department of Public Works February 25, 2010 Page 7 prepared by DELTA prior to initiating field activities and submitted with DELTA's work plan. Pacific Coast Locators, a utility locator contractor, performed a geophysical survey of the proposed boring locations on October 1, 2009. Notifications regarding field activities were made in advance to the appropriate agencies and property owner. DRILLING AND SAMPLE COLLECTION On October 13, 2009, Martini Drilling Corporation (Martini) supervised by a DELTA geologist, cleared three soil boring locations with air knife equipment to a depth of approximately 10 feet bgs. On October 14 and 15, 2009, Martini, supervised by a DELTA geologist, advanced a total of three confirmation soil borings (CB -1, CB -2, and CB -3) to approximately 100 feet bgs. The soil borings were completed using a CME 75 High Torque Truck Mounted Drill Rig equipped with six -inch hollow -stem augers. Soil samples were collected at five -foot intervals, beginning at 10 feet bgs to the total depth explored of approximately 100 feet bgs. Soil samples were collected for chemical analysis using a 2 -inch diameter California modified split spoon sampler equipped with stainless steel sample sleeves. At each sampling interval, the soil samples were logged by the field geologist using the Unified Soil Classification System. The sleeves were labeled and sealed at each end with Teflon® —lined plastic end caps and labeled in accordance with specified sampling procedures. Soil samples were sealed, labeled, and stored on ice for transport to a State of California certified analytical laboratory with the appropriate chain -of- custody documentation. Soil samples were field screened for the presence of volatile organic compounds (VOCs) by headspace analysis using a photo- ionization detector (PID) calibrated to 100 parts per million by volume (ppmv) of isobutylene. PI.D readings, lithology, and field observations are documented on the boring logs (Appendix B). EQUIPMENT DECONTAMINATION Hollow stem augers were pressure washed and rinsed prior to drilling each ofthe boring locations. Down -hole sampling equipment was washed between sampling intervals in a non - phosphate detergent and rinsed with distilled or de- ionized water. ANALYTICAL PROGRAM Soil samples collected were submitted to Cal Science, in Garden Grove, California, a California - certified analytical laboratory. Soil samples were analyzed for TPH -g, benzene, toluene, ethylbenzene, and total xylenes (BTEX compounds), fuel- oxygenates including MTBE, TBA, tert-amyl methyl ether (TAME), di- isopropyl ether DIPE), ethyl tert-butyl ether (ETBE), and ethanol using EPA Method 8260B. TPH -d was analyzed using the California Department of Health Services Leaking Underground Fuel Tank (CA / DHS LUFT) and EPA Method 8015 M. Mr. Craig Perkins County of Los Angeles Department of Public Works February 25, 2010 Page 8 WASTE DISPOSAL Soil cuttings, debris, and rinseate water generated during drilling activities was stored in Department of Transportation (DOT)- approved 55- gallon drums. The drums were sealed and labeled in accordance with SHELL's protocols. The waste was temporarily stored on site pending disposal coordination. Waste ws removed by Belshire Environmental Services, Inc (BESI) on November 10, 2009, and transported to Crosby and Overton in Long Beach, California (construction debris), Demenno Kerdoon of Compton, California decontamination water), and TPST Soil Recyclers of California in Adelanto, California (soil). Waste inventory records and disposal documentation are presented in Appendix D. FINDINGS SUBSURFACE CONDITIONS Soils encountered during site assessment activities consisted primarily of fine to medium grained sands with inter- bedded silty sands to the total depth explored of 100 feet bgs. Inter - bedded fine to coarse grained sands were encountered from approximately 55 feet bgs to approximately 90 feet bgs. Groundwater was not encountered in the confirmation soil borings. SOIL ANALYTICAL RESULTS A summary of soil analytical results follows, and the results are presented in Table 2 and displayed on Figure 3. Certified analytical reports are included in Appendix C. TPH -g was detected in one soil sample collected from confinnation soil boring CB -1 at a concentration of 0.59 milligrams per kilogram (mg/kg) [CB- ld50]. MTBE was detected in three soil samples collected from confinnation soil borings CB -2 and CB -3 at concentrations of 0.087 mg/kg (CB- 2d50), 0.19 mg/kg (CB- 3d45), and 0.73 mg/kg (CB- 360). Toluene was detected in one soil sample collected from confirmation soil boring CB -1 at a concentration of 0.0067 mg/kg (CB- ld25). TBA was detected in one soil sample collected from confirmation soil boring CB -3 at a concentration of 0.14 mg/kg (CB- 360). TPH -d, benzene, ethylbenzene, total xylenes, DIPE, ETBE and ethanol were not detected above laboratory reporting limits. Mr. Craig Perkins County ofLos Angeles Department of Public Works February 25, 2010 Page 9 SUMMARY Based on results obtained during the recent confirmation soil boring activities: Soils encountered during site assessment activities consisted primarily of fine to medium grained sands with inter - bedded silty sands to the total depth explored of 100 feet bgs. Inter- bedded fine to coarse grained well graded sands were encountered from approximately 55 feet bgs to approximately 90 feet bgs. Groundwater was not encountered in the confirmation soil borings. TPH -g, MTBE, Toluene, and TBA were detected above method detection limits in a small number of samples collected. TPH -d, Benzene, ethylbenzene, total xylenes, DIPE, ETBE and ethanol were not detected above method detection limits. CONCLUSIONS Based on the enclosed information, DELTA presents the following conclusions: Confirmation soil borings were drilled as requested in the May 8, 2009 meeting between Shell, BFD, and DELTA, and according to the Revised Work Plan for Soil Confirmation Borings dated September 17, 2009, which was approved by the CBFD in their letter dated September 23, 2009 (Appendix A). TPH -g was detected in one soil sample (CB -ld50) at a concentration of 0.59 mg/kg. TBA was detected in one soil sample (CB -360) at a concentration of 0.14 mg/kg. Neither TPH -g nor TBA are listed in the EPA Regional Screening Level (RSLs) (EPA, 2009) published in December 2009. Toluene was detected in one soil sample (CB -1d25) at a concentration of 0.0067 mg/kg, below the RSL for residential soils of 5,000 mg/kg. MTBE was detected in three soil samples collected from two borings (CB -260, CB -3445, and CB- 3d50) at concentrations between 0.087 mg/kg and 0.73 mg/kg. These concentrations are below the RSLs, for residential soils of 43 mg/kg. Based on the analytical results, 50 feet of clean soil has been verified below the deepest impacts observed, which indicates there is the potential threat to groundwater is low. In the Low -Risk Site Closure Request prepared by DELTA, dated May 12, 2008, DELTA presented the following conclusions and recommended case closure: The historical maximum TPH -d concentrations were detected in soil samples collected around the former UST complex (31 mg/kg, P- 2 -10); however, this area was subsequently over - excavated to non - detect TPH -d concentrations. Furthermore, since completion of SB898 UST upgrade activities in 2001, diesel has not been stored at the site, hence eliminating the source of TPH -d release. Mr. Craig Perkins County of Los Angeles Department of Public Works February 25, 2010 Page 10 TPH -g was detected at historical maximum concentrations of 15 mg/kg (BB -9 @ 20 feet bgs) in the shallow zone and 12 mg/kg (BB -12 @ 40 feet bgs) in the deep zone. However, according to First Quarter 2008 soil vapor analytical data, TPH -g was non- detect above laboratory reporting limits in wells VEW -5A/5B (adjacent to boring BB -9) and VEW -4A/4B (adjacent to boring BB -12). From soil vapor samples collected in the First Quarter 2008, TPH -g was only detected in well VEW -3B at 4.8 ppm or 20 gg/L. BTEX compounds were detected in soil samples around the former UST complex in soil sample P -2- 10; however, this area was subsequently over - excavated to non- detect concentrations. BTEX compounds were not detected in the remaining soil samples, with the exception of a concentration of 6.6 mg/kg of toluene in soil sample BB -18 at a depth of 65 feet bgs. In the First Quarter 2008, benzene and ethylbenzene were not detected in any soil vapor samples collected; toluene was detected at a maximum concentration of 0.0025 ppm (VEW -1 B and VEW -2A); total xylenes were non- detect in all soil vapor samples collected except in VEW -IA and VEW -213, both at 0.0010 ppm. Historically, the maximum MTBE concentrations were found in the soil samples collected in the area of the USTs. The maximum concentrations of MTBE detected were 51 mg/kg (BB -2 @ 20 feet bgs) in the shallow zone and 29 mg/kg (VEW -3 @ 40 feet bgs) in the deep zone. In the First Quarter 2008, MTBE was detected in soil vapor samples at a maximum concentration of 0.26 ppm (0.94 µg/L) in VEW -313. MTBE was not detected above laboratory reporting limits in soil vapor samples collected from VEW -2B, 4B, and 5B. Historical maximum TBA concentrations were detected near the former UST complex at 29 mg/kg VEW -5 @ 25 feet bgs) in the shallow zone and 4.2 mg/kg (VEW -5 @ 45 feet bgs) in the deep zone. However, TBA was non - detect above laboratory reporting limits in all of the soil vapor samples collected in the First Quarter 2008. DIPE, ETBE, and TAME have not been detected in any of the historical soil samples collected. DIPS, ETBE, and TAME were also non- detect above laboratory reporting limits in all of the soil vapor samples collected in the First Quarter 2008. Hydrocarbon concentrations in soil vapor since the start of MNA activities during the second quarter of 2005 have reduced asymptotically. In the First Quarter 2008, TPH -g was only detected in one soil vapor sample at 4.8 ppm in well VEW -3B. Toluene was detected at a maximum concentration of 0.0025 ppm (VEW -1B and VEW -2A). Xylenes were detected at maximum concentrations of 0.0010 ppm (VEW -IA and VEW -213). MTBE was detected at a maximum concentration of 0.26 ppm (VEW - 3B). Benzene, ethyl benzene, TBA, WE, ETBE, and TAME were not detected above laboratory reporting limits in any of the soil vapor samples collected during the First Quarter 2008. Hydrocarbon and fuel - oxygenate impacts to onsite soil and soil vapor have been characterized. 1 Mr. Craig Perkins County ofLos Angeles Department ofPublic Works February 25, 2010 Page 1 I t • Hydrocarbon impact to groundwater is unlikely to occur. The maximum depth explored during site assessment activities was 85 feet bgs, at which all constituents analyzed, except MTBE, were not detected above laboratory reporting limits. MTBE was detected in borings BB -13 through BB -20 at 100 feet bgs at a maximum concentration of 0.061 mg/kg (BB -15). Given that approximately 75 feet exists between the maximum soil sample depth and anticipated groundwater depth, the minimal MTBE concentrations detected at the maximum depth explored, and the additional 3,909 -foot distance to the receptor well, it is not likely that groundwater at the receptor well will be impacted. RECOMMENDATIONS A review of the analytical data presented in this report indicates limited residual hydrocarbons in soil beneath the site and an asymptotic reduction of hydrocarbons in soil vapor samples. Based on the conclusions of the soil confirmation borings and those presented in DELTA's Low -Risk Site Closure Request dated May 12, 2008, DELTA recommends low -risk case closure.

Dear Ms. Wing, I have reviewed the work plan submitted by Delta Consultants for the Shell Station located 4050 Gosford Road, Bakersfield Ca. I would like to see some changes in the location of the borings including the addition of one more boring (CB -4). First, move CB -2 closer to VEW 1A and 1B, and add CB-4 (new) in the vicinity of VEW 2A and 2B so we could capture a better representative sample in the heaviest contaminated area. Second, regarding the sensitive receptor section of your work plan, these schools and care centers do not exist in the area. Please make the appropriate adjustments and resubmit. Please resubmit a correction action plan to this office within 30 days from receipt this letter. The work plan should follow the guidelines found in: Appendix A: Reports.

Dear Ms. Wing, This office has reviewed the work plan revisions submitted by Delta Consultants for the Shell Station located 4050 Gosford Road, Bakersfield Ca. dated September 17, 2009. At this time we are in concurrence with the alterations of the three soil boring locations as indicated on the revised figure of the work plan. However, any indication of MTBE within the soil samples of those borings will require concurrence with the California Regional Water Quality Control Board prior to closure of this site.

The associated method blank surrogate spike compound was in control and, therefore, the sample data was reported without further clarification. 3 Recovery of the Matrix Spike (MS) or Matrix Spike Duplicate (MSD) compound was out of control due to matrix interference. The associated LCS and /or LCSD was in control and, therefore, the sample data was reported without further clarification. 4 The MS /MSD RPD was out of control due to matrix interference. The LCS /LCSD RPD was in control and, therefore, the sample data was reported without further clarification. 5 The PDS /PDSD associated with this batch of samples was out of control due to a matrix interference effect. The associated batch LCS /LCSD was in control and, hence, the associated sample data was reported with no further corrective action required. A Result is the average of all dilutions, as defined by the method. B Analyte was present in the associated method blank. C Analyte presence was not confirmed on primary column. E Concentration exceeds the calibration range. H Sample received and /or analyzed past the recommended holding time. J Analyte was detected at a concentration below the reporting limit and above the laboratory method detection limit. Reported value is estimated. ME LCS Recovery Percentage is within LCS ME Control Limit range. N Nontarget Analyte. ND Parameter not detected at the indicated reporting limit. Q Spike recovery and RPD control limits do not apply resulting from the parameter concentration in the sample exceeding the spike concentration by a factor of four or greater.

The associated method blank surrogate spike compound was in control and, therefore, the sample data was reported without further clarification. 3 Recovery of the Matrix Spike (MS) or Matrix Spike Duplicate (MSD) compound was out of control due to matrix interference. The associated LCS and /or LCSD was in control and, therefore, the sample data was reported without further clarification. 4 The MS /MSD RPD was out of control due to matrix interference. The LCS /LCSD RPD was in control and, therefore, the sample data was reported without further clarification. 5 The PDS /PDSD associated with this batch of samples was out of control due to a matrix interference effect. The associated batch LCS /LCSD was in control and, hence, the associated sample data was reported with no further corrective action required. A Result is the average of all dilutions, as defined by the method. B Analyte was present in the associated method blank. C Analyte presence was not confirmed on primary column. E Concentration exceeds the calibration range. H Sample received and /or analyzed past the recommended holding time. J Analyte was detected at a concentration below the reporting limit and above the laboratory method detection limit. Reported value is estimated. ME LCS Recovery Percentage is within LCS ME Control Limit range. N Nontarget Analyte. 1 ND Parameter not detected at the indicated reporting limit. Q Spike recovery and RPD control limits do not apply resulting from the parameter concentration in the sample exceeding the spike concentration by.a factor of four oragreater.
