Work was conducted in general accordance with SECOR's "Site Assessment" dated June 28, 2006, and approved by the Bakersfield Fire Department(BFD), in their letter dated August 25, 2006 (Appendix A). The purpose of this assessment was to assess the extent of petroleum hydrocarbon impact to soil in the vicinity of the #2 Dispenser (Figure 2). The scope of work performed during the site assessment included: o Preparing and submitting an assessment work plan to the regulatory agency; Obtaining a drilling permit from the BFD for the installation of two soil borings; o Preparing a site-specific health and safety plan (SHSP); Notifying Underground Service Alert (USA) and a private utility locator to identify and mark subsurface utilities; e Drilling two soil boreholes (B-8 and B-9); Collecting soil samples at approximate five foot intervals; Logging lithologies of soil cuttings and samples collected during drilling operations; Screening soil samples collected during drilling activities using an organic vapor analyzer (OVA); Analyzing soil samples for gasoline range organics (GRO); for benzene, toluene, ethylbenzene, and xylenes (BTEX); and for the fuel oxygenates di-isopropyl ether (DIPE), ethyl tert-butyl ether (ETBE), tert-amyl methyl ether (TAME), methyl tert-butyl ether (MTBE), tert-butyl alcohol (TBA), and ethanol; and Preparing this report, which summarizes the site assessment procedures and findings. All field activities were supervised by Stratus Environmental, Inc. (Stratus) including utility clearance, supervision of drilling activities, sample collection, and handling, logging soils, and preparation of boring logs. SECOR has prepared this report including interpretations and recommendations based on the data provided by Stratus. R:ARCO\OODesert Sites\5365\AR5365(SAR 070309).doc Page 1 March 9,2007 SECOR 2.0 SITE DESCRIPTION 2.1 Site Description ARCO Facility#5365 (the site) is at 4010 Wible Road in Bakersfield, California (Figure 1); at an elevation of approximately 372 feet above mean sea level. The site is on the northeast corner of Wible Road and White Road. Local topography slopes to the south-southwest at approximately 0.001 feet per foot (USGS, 1954). Currently an operating Atlantic Richfield retail gas station and am/pm minimart, there are four 12,000-gallon double-walled, fiberglass gasoline underground storage tanks (USTs), and six gasoline dispensers (Figure 2). 2.2 Regional Geology and Hydrogeology The site is approximately 4,800 feet east of the Farmer's Canal, approximately 5,200 feet west of the Stine Canal, and approximately eight miles south of the Kern River, and is underlain by alluvial fan deposits comprised of silt, sand, and clay. Depth to groundwater in the region is noted to be widely variable and seasonal. Depth to water measurements collected from a 7- Eleven service station, at 1701 Pacheco Road (approximately 5,200 feet to the southeast of the site) indicate that the depth to water ranges from approximately 40 feet below ground surface (bgs) to approximately 58 feet bgs (Http://geotracker.swrcb.ca.gov). Based on information provided by the Kern County Water Authority, depth to groundwater in the vicinity of the site is estimated at approximately 180 feet bgs (KCWA, 1992). During assessment activities at the site in 1994, soil borings were advanced to a depth of 45 feet and groundwater was not encountered. Approximately 60 percent of the municipal water supply in Kern County is derived from groundwater supplies. A regional confining layer known as the Corcoran Clay, or E-Clay, occurs at approximately 200 to 300 feet bgs and has an average thickness of approximately 55 feet (Kennedy, 1990). The Corcoran Clay separates a semi-confined to unconfined aquifer (above)from a confined aquifer system (below; Kennedy, 1990). Groundwater flow beneath the site is estimated to be south-southwest, or identical to topography(Kennedy, 1990). 2.3 Site Geology and Hydrogeology Soil types encountered during site assessment activities consisted primarily of sand with interbedded layers of clayey sand, silt, and clay to a depth of approximately 60 feet below ground surface (bgs) the maximum depth of investigation. Groundwater was not encountered. Geologic cross section A-A' is presented as Figure 3. Boring logs are included.in Appendix B. 2.4 Site Background In July 1993, Groundwater Technology, Inc. (GTI) performed preliminary site assessment activities at the site. Two soil borings were drilled near the fill ends of the tanks (131 and 132) and one boring was drilled in the middle of the proposed tank location (63). Total depth of the borings ranged from approximately 20 to 30 feet bgs. TPHg and benzene were not detected in any of the soil samples analyzed. Toluene, ethylbenzene, and xylenes were detected in soil PAARC0\00Desert Sites\5365\AR5365(SAR 070309).doc Page 2 March 9,2007 SECOR boring B3 at a depth of 15 feet bgs, at concentrations of 0.066 milligrams per kilogram (mg/kg), 0.017 mg/kg, and 0.36 mg/kg, respectively(Appendix C; GTI, 1994). In August 1993, GTI oversaw the removal of the three underground storage tanks (USTs) and associated product piping from the site. A total of 16 soil samples were collected at locations designated by the on-site representative from the BFD. GRO and benzene, toluene, ethylbenzene, and xylenes (collectively BTEX) were detected in soil samples at maximum concentrations of 9,900 mg/kg (GRO - D2E), 95 mg/kg (benzene - D2E), 750 mg/kg (toluene - D2E), 390 mg/kg (ethylbenzene - T1-6'), and 1,200 mg/kg (xylenes - D2E) (Appendix C; GTI, 1994). On May 19, 1994 GTI supervised the installation of four soil borings (134 through 137) at the site. GRO and BTEX were detected in soil sample 136-8 at concentrations of 1,400 mg/kg (GRO), 0.14 mg/kg (benzene), 3.0 mg/kg (toluene), 5.8 mg/kg (ethylbenzene), and 42.0 mg/kg (xylenes), respectively. Benzene was also detected at a concentration of 0.020 mg/kg in soil sample 67-45 (Appendix C; GTI, 1994). This case was granted regulatory closure by the City of Bakersfield in August 1994 (City of Bakersfield, 1994). On November 4, 1998, Kern Construction excavated six new canopy footings in the area of the dispenser islands. The footings were excavated to a total depth of approximately 10 feet below ground surface (bgs), and had surface dimensions of 4 feet by 4 feet in diameter. SECOR performed air monitoring during the excavation using a Heath-Tech Flame Ionization Detector. Elevated concentrations of volatile organic compounds (VOCs) were detected during the excavation of the second canopy footing (Footing 2). Concentrations of VOCs measured during the excavation of the remaining five canopy footings (Footings 1,3,4,5, and 6) were either non- detectable or below 50 parts per million by volume (ppmv). Soil excavated from Footing 2 was stockpiled separately for sampling and analytical characterization. SECOR collected five stockpile samples (SP-1 through SP-5) from the generated soil stockpiles. Soil samples were submitted for analyses of GRO and BTEX and MTBE by EPA Methods 8015M and 8020, respectively. Varying concentrations of GRO were detected in each of the five samples. The highest concentration, 4,200 mg/kg, was detected in sample SP-1 which originated from the second canopy footing (Footing 2; Appendix C). Lower concentrations of GRO (1.8 to 250 mg/kg) were detected in the remaining four samples (SP-2 through SP-5) from the other footing excavations. A benzene concentration of 0.41 mg/kg was detected in one of the five samples (SP-3). MTBE was not detected above laboratory reporting limits (RLs) in any of the five samples (Appendix C; SECOR, 1998). On December 12, 2005, SECOR collected 12 soil samples in association with dispenser secondary containment upgrade activities performed by Belshire Environmental Services (Belshire). Soil samples were collected beneath each of the six dispensers (DS-1 through DS- 6) under the direction of BFD Fire Prevention Officer, Mr. Steve Underwood. Detectable concentrations of petroleum hydrocarbon constituents above the laboratory RLs were identified in four of the 12 samples. Concentrations of GRO were detected in three samples, with the maximum reported concentration of 1,200 mg/kg (DS-2-5); toluene was detected in one sample at a concentration of 0.0026 mg/kg (DS-2-3); ethylbenzene was detected in two samples with a maximum reported concentration of 0.012 mg/kg (DS-2-5); and total xylenes concentrations were detected in two samples with the maximum reported concentration of 0.12 mg/kg (DS-2-5). Benzene; MTBE, and TBA were not detected above the laboratory RLs (SECOR, 2006).

The locations of historical soil samples collected during previous site assessment activities are shown on the figures provided in Appendix C. P:\ARCO\OODesert Sites\5365\AR5365(SAR 070309).doc Page 4 March 9,2007 SECOR 3.0 SITE ASSESSMENT Stratus Environmental, Inc. (Stratus) drilled, installed and sampled two soil borings, and submitted soil samples to an Atlantic Richfield approved and California Department of Health Services certified laboratory for chemical analysis. Field activities were conducted in general accordance with the BFD-approved work plan (Appendix A), and using methods reviewed and approved by a California Professional Geologist. The following sections summarize the site assessment methods. 3.1 Pre-Field Activities 3.1.1 Health and Safety Plan - Work performed by Stratus at the site was conducted according to guidelines established in a SHSP. The SHSP is a document which describes the hazards that may be encountered in the field and specifies protective equipment, work procedures, and emergency information. A copy of the SHSP was at the site and available for reference by appropriate parties during work at the site. 3.1.2 Soil Boring Installation Pursuant to the requirements of the approved permit, the BFD was notified of the intent to drill at least five days prior to drilling. 3.1.3 Locate Underground Utilities Prior to commencement of any work that is to be below surface grade, the location of the soil borings were marked with white paint as required by law. An underground locating service such as underground service alert (USA) was contacted. The locating company contacted the owners of the various utilities in the vicinity of the site to mark the locations of underground utilities. In addition, a private utility locating company was contacted to further clear the drilling areas using geophysical methods. Any invasive work was preceded by air knifing the borehole location to a minimum depth of five feet bgs to avoid contact with underground utilities. 3.2 Field Methods and Procedures 3.2.1 Exploratory Soil Borings On November 30, 2006, two soil borings (13-8 and B-9)were drilled by JDK Drilling, Inc., using a truck-mounted, hollow stem auger drill rig. The soil boreholes were drilled to a depth of approximately 60 feet bgs. Soil samples for logging were obtained from auger-return materials and by advancing a modified California split-spoon sampler equipped with brass or stainless steel liners into undisturbed soil beyond the tip of the auger at approximately five foot intervals. Soils were logged by a geologist according to the Unified Soil Classification System (USCS) and standard geological techniques. Drill cuttings were screened using a portable organic vapor PAARCOWDesert Sites\5365WR5365(SAR 070309).doc Page 5 March 9,2007 SECOR analyzer (OVA). The exploratory soil borings were not used for monitoring well installation, and were backfilled to the surface with a bentonite grout slurry pumped into the borings. Soil sampling equipment was cleaned with a detergent water solution, rinsed with clean water, and lined with clean sample tubes between sampling intervals. Augers and samplers, were steam cleaned between each boring to reduce the possibility of cross contamination. Steam cleaning effluent was contained in 55-gallon drums and temporarily stored on site. Drill cuttings generated during the drilling procedure were placed in 55-gallon Department of Transportation (DOT)-approved steel drums and temporarily stored on site. Upon receipt of laboratory results, waste was transported off-site for disposal by Belshire Environmental Services (BEST). Soil was transported to TPST Soil Recycling of California for recycling, and waste water was hauled to DeMenno Kerdoon for disposal. A copy of the waste manifests are included in Appendix D. - 3.2.2 Soil Sample Collection During drilling, soil samples were collected in cleaned brass or stainless steel tubes set in an 18-inch-long split-barrel sampler. The sampler was conveyed to the bottom of the borehole attached to a wire-line hammer on the drill rig. The number of blows used to drive the sampler were recorded on the boring logs. The sampler was extracted from the borehole, and the tubes containing the soil samples were removed. Soil samples were collected for laboratory analysis using Encore samplers according to United States Environmental Protection Agency (EPA) Method 5035. The samples were placed on ice and delivered to a state-certified analytical laboratory, along with the appropriate chain-of- custody documentation. Please refer to Appendix B for further details regarding field procedures. 3.2.3 Soil Classification Soil samples were classified by the field geologist in accordance with the USCS. Field procedures and boring logs are included in Appendix B. 3.2.4 Soil Sample Screening Soil samples were screened in the field for volatile organic vapors using an OVA. The total volatile hydrocarbons present were detected by the OVA and reported in parts per million (ppmv). Soil samples were submitted to a state certified laboratory for chemical analysis according to the agency approved work plan. The analytical results were used to profile the drummed waste for treatment and recycling.

All 23 soil samples were analyzed for GRO (C4— C12) by EPA Method 8015M and for BTEX, DIPE, ETBE, TAME, MTBE, TBA, and ethanol by EPA Method 82608. M PAARCO\OODesert Sites\5365\AR5365(SAR 070309).doc Page 7 March 9,2007 SECOR 4.0 FINDINGS 4.1 Site Specific Geology Soil types encountered during site assessment activities consisted primarily of sand with interbedded layers of clayey sand, silt, and clay to a depth of approximately 60 feet below ground surface (bgs) the total depth of investigation. Groundwater was not encountered during site assessment activities. Geologic cross section A-A' is presented as Figure 3. Boring logs are included in Appendix B. 4.2 Analytical Results During this phase of assessment, GRO, BTEX, MTBE, TAME, ETBE, DIPE, TBA, and ethanol were not detected above the laboratory RLs in any of the soil samples submitted for laboratory analysis. Soil sample analytical results for the site are summarized in Table 1. GRO, benzene, and MTBE soil sample analytical results are shown on Figures 3 and 4. The laboratory report and chain-of-custody documentation are provided in Appendix B. P:\ARCO\OODesert Sites\5365\AR5365(SAR 070309).doc Page 8 March 9,2007 SECOR 5.0 CONCLUSIONS AND RECOMMENDATIONS The lateral and vertical extent of adsorbed phase hydrocarbon impacted soil detected during facility upgrade and site assessment activities, has been adequately characterized. Sufficient analytical data has been collected from site soil samples to establish that the hydrocarbon impact has been defined. Concentrations of GRO, benzene, and MTBE were not detected above the laboratory RLs during the site assessment activities. Based on the results of this and previous environmental assessment at the site, SECOR presents the following conclusions: • Petroleum hydrocarbons characterized as gasoline appear to be limited to shallow soils above 10 feet bgs. • The lateral and vertical extent of hydrocarbon impacted soil is sufficiently defined by this and previous assessment. • Groundwater was not encountered during drilling. • No petroleum hydrocarbon constituents were detected above the laboratory RLs during the site assessment activities. Based on the evaluation of the site conditions, SECOR recommends no additional site assessment. The soil impact is limited to the first five feet bgs, and has been defined by the recent site assessment activities. On behalf of Atlantic Richfield, SECOR requests that case closure be considered and a "No Further Action" letter be issued for this site.

Secor International Inc. 2655 Camino Del Rio North .: San Diego, California 92108 Re: Soil Boring Data Package Submittal ARCO Station No. 5365 4010 Wible Road Bakersfield, CA Dear Ms. Farr: On behalf of Atlantic Richfield Company, Stratus Environmental, Inc. (Stratus) is submitting a Soil Boring Data Package to Secor International Inc. (Secor) for completion of two soil borings drilled to a depth of 60 feet below ground surface at the referenced site. Stratus completed the work under direct contract with Atlantic Richfield. On November 15, 2006 a.Stratus representative was onsite to observe geophysical utility locating and air knifing activities. The underground utility clearance report and driller's daily work report are included as an attachment to this letter. On November 30, 2006 a Stratus geologist was onsite to supervise the installation two soil borings, B-8 and B-9, to a depth of sixty feet below ground surface. The borings were located near the southwest dispenser island. Soil samples were collected at 5 foot intervals for laboratory analyses using EnCore soil samplers (per EPA Method 5035). A boring log for each boring was created which recorded soil types, PID values and other pertinent geological data. The boring logs, field notes, site map, site pictures, Underground Service Alert form, PID calibration log, drum inventory record, driller's daily report, laboratory chain of custody, and Stratus' Standard Field Practices and Procedures are included as an attachment to this letter. Soil samples were shipped overnight by FedEx to Test America Laboratory in Irvine, California. Laboratory analytical results are provided electronically by Test America. An electronic copy of this data package will be uploaded into ENFOS by December 20,2006. Please call Ron Bailey at (714) 230-2495 if you have any questions regarding the information contained in this data package. Sincerely, Stratus Environmental,Inc. 5 °"A c F o �4c.

FIELD PRACTICES AND .PROCEDURES General procedures used by Stratus in site assessments for drilling exploratory borings, collecting samples, and installing monitoring wells are described herein. These general procedures are used to provide consistent and reproducible results; however, some procedure may be modified based on site conditions. A California registered Professional Geologist supervises the following procedures. PRE-FIELD WORK ACTIVITIES Health and Safety Plan Field work performed by Stratus at the site is conducted according to guidelines established in a Site Health and Safety Plan (SHSP). The SHSP is a document which describes the hazards that may be encountered in the field and specifies protective equipment, work procedures, and emergency information. A copy of the SHSP is at the site and available for reference by appropriate parties during work at the site. Locating Underground Utilities Prior to commencement of any work that is to be below surface grade, the location of the excavation, boring, etc., is marked with white paint as required by law. An underground locating service such as Underground Service Alert (USA) is contacted. The locating company contacts the owners of the various utilities in the vicinity of the site to mark the locations of their underground utilities. In addition, a private utility locating company is contracted to further clear the drilling area(s) using geophysical methods. Any invasive work is preceded by air knifing the borehole location to a minimum depth of five feet below surface grade to avoid contact with underground utilities. FIELD METHODS AND PROCEDURES Exploratory Soil Borings Soil borings will be drilled using a truck-mounted, hollow stem auger drill rig. Soil samples for logging will be obtained from auger-return materials and by advancing a modified California split-spoon sampler equipped with brass or stainless steel liners into undisturbed soil beyond the tip of the auger. Soils will be logged by a geologist according to the Unified Soil Classification System and standard geological techniques. Drill cuttings will be screened using a portable photoionization detector (PID) or a flame ionization detector (FID). Exploratory soil borings not used for monitoring well installation will be backfilled to the surface with a bentonite grout slurry pumped into the boring. KASOPOrillingField Practices and Procedures-revised 12-2006.doc Stratus Environmental, Inc. Field Practices and Procedures Page 2 Soil sampling equipment will be cleaned with a detergent water solution, rinsed with clean water, and equipped with clean liners between sampling intervals. Augers and samplers will be steam cleaned between each boring to reduce the possibility of cross contamination. Steam cleaning effluent will be contained in 55-gallon drums and temporarily stored on site. The disposal of the effluent will be the responsibility of the client. Drill cuttings generated during the drilling procedure will be placed in 55-gallon DOT- approved steel drums and temporarily stored on site. Upon receipt of laboratory results, Stratus coordinates with a licensed waste hauler to remove the drummed waste and transport it to a licensed recycling facility under manifest. Soil Sample Collection During drilling, soil samples will be collected in cleaned brass or stainless steel, two by six inch tubes. The tubes will be set in an 18-inch-long split-barrel sampler. The sampler will be conveyed to bottom of the borehole attached to a wire-line hammer device on the drill rig. When possible, the split-barrel sampler will be driven its entire length, either hydraulically or by repeated pounding a 140-pound hammer using a 30-inch drop. The number of drops (blows) used to drive the sampler will be recorded on the boring log. The sampler will be extracted from the borehole, and the tubes containing the soil samples will be removed. Upon removal, the ends of the lowermost tube will be sealed with Teflon sheets and plastic caps. Soil samples for chemical analysis will be labeled, placed in a cooler on ice, and delivered to a state-certified analytical laboratory, along with the appropriate chain-of-custody documentation. In certain jurisdictions, soil samples are collected using Encore samplers according to EPA Method 5035. Either 5 or 25 gram samplers can be used. The samplers are placed in a tee handle tool and driven into undisturbed soil that is either contained in the sample tube or within the split-spoon sampler. The sampler is filled to capacity, capped, removed from the tool and placed in a labeled pouch provided by the manufacturer. The pouch is placed on ice and delivered to a state-certified analytical laboratory, along with the appropriate chain-of-custody documentation. Soil Classification As the samples are obtained in the field, they will be classified by the field geologist in accordance with the Unified Soil Classification System. Representative portions of the samples will be retained for further examination and for verification of the field classification. Logs of the borings indicating the depth and identification of the various strata and pertinent information regarding the method of maintaining and advancing the borehole will be prepared. ` STPXr KASOPOrillingField Practices and Procedures-revised 12-2006.doc Stratus Environmental,Inc. Field Practices and Procedures Page 3 Soil Sample Screening Soil samples selected for chemical analysis will be determined from a head-space analysis using a PID or an FID. The soil will be placed in a Ziploc® bag, sealed, and allowed to reach ambient temperature, at which time the PID probe will be inserted into the Ziploc® bag. The total volatile hydrocarbons present are detected by the PID and reported in parts per million by volume (ppmv). The PID will be calibrated to an isobutylene or hexane standard. Soil samples will be submitted to a state certified laboratory for chemical analysis according to the agency approved work plan. The analytical results are used to profile the drummed waste for treatment and recycling. Direct Push Technology, Water Sampling A well known example of direct push technology for water sampling is the Hydropunce. For the purpose of this field method the term hydropunch will be used instead of direct push technology for water sampling. The hydropunch is typically used with a drill rig. A boring is drilled with hollow stem- augers to just above the sampling zone. In some soil conditions the drill rig can push directly from the surface to the sampling interval. The hydropunch is conveyed to the bottom of the boring using drill rods. Once on bottom the hydropunch is driven a maximum of five feet. The tool is then opened by lifting up the drill rod no more than four feet. Once the tool is opened, water enters and a sample can be collected with a bailer or tubing utilizing a peristaltic pump. Soil particles larger than silt are prevented from entering the tool by a screen within the tool. The water sample is collected, labeled, and handled according to the Quality Assurance Plan. Monitoring Well Installation Monitoring wells will be completed by installing 2 to 6 inch-diameter Schedule 40 polyvinyl chloride (PVC) casing. The borehole diameter for a monitoring well will be a minimum of four inches larger than the outside diameter of the casing. The 2-inch-diameter flush-threaded casing is generally used for wells dedicated for groundwater monitoring purposes. A monitoring well is typically cased with threaded, factory-perforated and blank Schedule 40 PVC. The perforated interval consists of slotted casing, generally with 0.01 or 0.02 inch-wide. The screened sections of casing are factory machine slotted and will be installed approximately 5 feet above and 10 feet below first-encountered water level. The screened interval will allow for seasonal fluctuation in water level and for monitoring floating product. A threaded or slip PVC cap is secured to the bottom of the 5TPi1TU5 ENVIRONMENTAL,INC KASOPOrillingField Practices and Procedures-revised 12-2006.doc Stratus Environmental, Inc. Field Practices and Procedures Page 4 casing. The slip cap can be secured with stainless steel screws or friction; no solvents or cements are used. Centering devices may be fastened to the casing to ensure even distribution of filter material and grout within the borehole annulus. The well casing is thoroughly washed and/or steam cleaned, or may be purchased as pre-cleaned, prior to completion. A filter pack of graded sand will be placed in the annular space between the PVC casing and the borehole wall. Sand will be added to the borehole through the hollow stem of the augers to provide a uniform filter pack around the casing and to stabilize the borehole. The sand pack will be placed to a maximum of 2 feet above the screens, followed by a minimum 1-foot seal consisting of bentonite pellets. Liquid bentonite grout will be placed above the bentonite seal to the ground surface. A concrete. traffic-rated vault box will be installed over the monitoring well(s). A watertight locking cap will be installed over the top of the well casing. Reference elevations for each monitoring well will be surveyed when more than two wells will be located on site. Monitoring well elevations will be surveyed by a California licensed surveyor to the nearest 0.01-foot relative to mean sea level (MSL). Horizontal coordinates of the wells will be measured at the same time. Exploratory boring logs and well construction details will be prepared for the final written report. ar,��rus ENVIRONMENTAL.INC.

The services provided by SECOR included the following: • Collecting soil samples following removal of the dispensers and pea gravel as directed by the Bakersfield Fire Department(BFD); and • Preparation of this technical report. ' SITE INFORMATION ' The Site is located at 4010 Wible Road in Bakersfield, California; at an elevation of approximately 372 feet above mean sea level. The Site is located on the northwest corner of Wible Road and White Road. Local topography slopes to the south-southwest at approximately 0.001 feet per foot (USGS, 1954). Currently an operating Atlantic Richfield retail gas station and am/pm minimart, there are four 12,000-gallon double ' walled, fiberglass gasoline underground storage tanks (USTs), and six gasoline dispensers. ' SITE BACKGROUND The Site is located approximately 4,800 east of the Farmer's Canal, and 5,200 feet west of the Stine Canal and approximately eight miles south of the Kern River, and is underlain by alluvial fan deposits comprised of silt, sand, and clay. Depth to groundwater in the region is noted to be widely variable and seasonable. Approximately 60 percent of the municipal water supply in Kern County is derived from groundwater supplies. A regional confining layer known as the Corcoran Clay or E-clay is located at approximately 200 to 300 feet bgs and has an average thickness of approximately 55 feet (Kennedy, 1990). The Corcoran clay separates a semi-confined to unconfined aquifer (above) from a confined aquifer system (below; KCWA, 1990). Groundwater flow beneath the Site is estimated to be south- ' southwest, or identical to topography(KCWA, 1990) Dispenser Secondary Containment Upgrade Report Atlantic Richfield Station No. 5365 ' Bakersfield, California Page 2 DISPENSER REMOVAL AND REPLACEMENT ' Belshire. Environmental Services (Belshire) was contracted by Atlantic Richfield to make all required preliminary notifications, as well as remove penetration fittings below the dispensers and replace them ' with pan entry fittings. The Construction Permit for the replacement of penetration fittings with pan,entry fittings is included in Appendix A. The following section summarizes the replacement activities: On December 12, 2005, Belshire completed the replacement of all total containment bottom-entry ' pentetrations below the dispensers and repaired and tested the spill buckets that failed on June 6, 2005. The dispenser locations are shown in Figure 2. Pea gravel was removed and re-used and placed into the trenches upon completion of the replacement activities. SOIL SAMPLING ' SECOR collected soil samples under the direction of the BFD Fire Prevention Officer Mr.i Steve Underwood. Field activities were conducted in accordance with the procedures for soil sampling included in Appendix B. The dispenser sample locations are indicated on Figure 2. This section summarizes the results of the soil sampling activities. Lead Agencies: Bakersfield Fire Department ' Permit No. MOD-0388 ' ' Agency Contact Name: Steve Underwood, Fire Prevention Officer (661)326-3190 Number of Dispenser Samples: 12 Dispenser Sample Names: DS-1-3, D9-1-5, DS-2-3, DS-2 75, DS-3-3, DS-3-5, DS-4-3, DS-4-5, DS-5-3, DS- 5-5, DS-6-3, and ' DS-6-5. ANALYTICAL RESULTS All soil samples were relinquished to Del Mar Analytical of Irvine, California (Del Mar) for,chemical'analysis. Del Mar is an Atlantic Richfield-contracted and California Department of Health Services certified laboratory. ' SECOR and Del Mar adhered to strict chain-of-custody procedures from sample collection to sample analysis. All soil samples were analyzed in accordance.with the appropriate Environmental Protection Agency(EPA) method and for the following analytes: • Gasoline Range Organics (GRO C4—C12) by EPA Test Method 82606; and • Benzene, toluene, ethylbenzene, and xylenes (BTEX), disopropyl ether (DIPE), !ethyl tertiary-butyl ' ether (ETBE), tertiary-amyl methyl ether (TAME), methyl tertiary-butyl ether (MTBE), tertiary-butanol (TBA), and ethanol by EPA Test Method 8260B. A total of 12 soil samples were collected from beneath the,dispensers. Detectable concentrations of ' petroleum hydrocarbon constituents above the laboratory reporting limit (RL) were identified in four of the 12 samples. Concentrations qualified by a "J-flag" are estimated values detected at a level below the RL and above the method detection limit (MDL). EPA-certified labs therefore advise that users of these data should be aware that these data are of unknown quality. Benzene; MTBE,and TBA were not detected Dispenser Secondary Containment Upgrade Report Atlantic Richfield Station No. 5365 Bakersfield,California '. Page 3 above the.laboratory RL in any of the soil samples collected. GRO was detected in three samples with the highest concentration of 1,200 mg/kg (DS-2-5), toluene was detected in one sample with a concentration ' of 0.0026 mg/kg (DS-2-3), Ethylbenzene was detected in two samples with 'a highest concentration of 0.012 mg/kg (DS-2-5)-and,total xylenes were detected in two samples with the highest concentration of 0.12 mg/kg (DS-2-5). The soil sample analytical results are summarized in Table 1. A copy of the certified laboratory analytical reports and chain-of=custody documentation are included in Appendix C. Based on the discovered,impact to subsurface soils, an Unauthorized Release Report was submitted by Atlantic Richfield and is provided in Appendix D. SUMMARY ' -On December 12, 2005, Belshire completed the replacement of all total containment bottom-entry pentetrations below the dispensers'and 'repaired and tested the spill buckets that failed on June 6,' 2005. A total of 12 soil samples were collected from beneath the dispensers for..confirmation ' purposes. Benzene, MTBE and TBA were not detected above the laboratory iRL in any of the soil samples collected. GRO, toluene, ethylbenzene, and total xylenes were detected at concentrations of 1,200 mg/kg (DS-2-5), 0.0026 mg/kg.(DS-2-3), 0.012 mg/kg (DS-2-5), and 0.12 mg.kg (DS 72-5), ' respectively. i • Based on the discovered impact to ,subsurface soils, an Unauthorized Release Report was submitted by Atlantic Richfield.

Wines, III Bakersfield Fire Department Hazardous Materials Division 900 Truxtun Avenue, Suite 210 Bakersfield, California 93301 Re: Site Assessment Workplan ARCO Facility 5365 4010 Wible Road Bakersfield, California Dear Mr. Wines: SECOR International Incorporated (SECOR) on behalf of Atlantic Richfield Company (Atlantic Richfield) has prepared this work plan to assess and define the presence of hydrocarbon impact detected in soil at the above referenced site. The work plan has been prepared in response to a directive from the Bakersfield Fire Department (BFD) received on May 2, 2006 requesting submittal of a work plan to address further hydrocarbon impact at the Site. Agency letters are provided as Attachment A. Included in this work plan are discussions on site description, geologic and hydrogeologic setting, site background, and proposed scope of work. SITE DESCRIPTION ARCO Facility#5365 (the Site) is located at 4010 Wible Road in Bakersfield, California (Figure 1); at an elevation of approximately 372 feet above mean sea level. The Site is located on the northwest corner of Wible Road and White Road. Local topography slopes to the south-southwest at approximately 0.001 feet per foot (USGS, 1954). Currently an operating Atlantic Richfield retail gas station and am/pm minimart, there are four 12,000-gallon double walled, fiberglass gasoline underground storage tanks (USTs), and six gasoline dispensers (Figure 2). GEOLOGY AND HYDROGEOLOGY Regional Geology and Hydrogeology The Site is located approximately 4,800 feet east of the Farmer's Canal, approximately 5,200 feet west of the Stine Canal, and approximately eight miles south of the Kern River, and is underlain by alluvial fan deposits comprised of silt, sand, and clay. Depth to groundwater in the region is noted to be widely variable and seasonal. Depth to water measurements collected from a 7-Eleven service station, located at 1701 Pacheco Road (approximately 5,200 feet to the southeast of the Site) indicate that the depth to water ranges from approximately 40 feet below ground surface (bgs) to approximately 58 feet bgs (Http://geotracker.swrcb.ca.gov). Based on information provided by the Kern County Water Authority, depth to groundwater in the vicinity of the Site is estimated at approximately 180 feet bgs (KCWA, 1992). During assessment activities at the site in 1993, soil borings we advanced to a maximum depth of 45 feet and groundwater was not encountered. Approximately 60 percent of the municipal water supply in Kern County is derived from groundwater supplies. A regional confining layer known as the Corcoran Clay, or E-Clay, is located at Mr. Howard H. Wines, III SECOR Job No. 08BP.05365.06 June 28, 2006 Page 2 approximately 200 to 300 feet bgs and has an average thickness of approximately 55 feet(Kennedy, 1990). The Corcoran Clay separates a semi-confined to unconfined aquifer(above)from a confined aquifer system (below; Kennedy, 1990). Groundwater flow beneath the Site is estimated to be south-southwest, or identical to topography(Kennedy, 1990). SITE BACKGROUND In July 1993, Groundwater Technology, Inc. (GTI) performed preliminary site assessment activities at the Site. Two soil borings were drilled near the fill ends of the tanks (131 and B2) and one boring was drilled in the middle of the proposed tank location (63). Total depth of the borings ranged from approximately 20 to 30 feet bgs. TPHg and benzene were not detected in any of the soil samples analyzed. Toluene, ethylbenzene, and xylenes were detected in soil boring B3 at a depth of 15 feet bgs, at concentrations of 0.066 milligrams per kilogram (mg/kg), 0.017 mg/kg, and 0.36 mg/kg, respectively(Appendix B; GTI, 1994). In August 1993, GTI oversaw the removal of the three underground storage tanks (USTs) and associated product piping from the Site. A total of 16 soil samples were collected at locations designated by the on-Site representative from the BFD. TPHg, benzene, toluene, ethylbenzene, and xylenes (collectively BTEX) were detected in soil'samples at maximum concentrations of 9,900 mg/kg (D2E), 95 mg/kg (D2E), 750 mg/kg (D2E), 390 mg/kg (T1-6'), and 1,200 mg/kg (D2E), respectively(Appendix B; GTI, 1994). On May 19, 1994 GTI supervised the installation of four soil borings (134 through 137) at the Site. TPHg and BTEX were detected in soil sample 66-8 at concentrations of 1,400 mg/kg, 0.14 mg/kg, 3.0 mg/kg, 5.8 mg/kg, and 42.0 mg/kg, respectively. Benzene was also detected at a concentration of 0.020 mg/kg in soil sample 137-45(Appendix B; GTI, 1994). On December 12, 2005, SECOR collected 12 soil samples in association with dispenser secondary containment upgrade activities performed by Belshire Environmental Services (Belshire). Soil samples were collected beneath each of the six dispensers (DS-1 through DS-6) under the direction of BFD Fire Prevention Officer, Mr. Steve Underwood. Detectable concentrations of petroleum hydrocarbon constituents above the laboratory reporting limit (RL) were identified in four of the 12 samples. Concentration of C4-C12 Gasoline Range Organics (GRO)were detected in three samples, with the maximum reported concentration of 1,200 milligrams per kilogram (mg/kg; DS-2-5); toluene was detected in one sample with a concentration of 0.0026 mg/kg (DS-2-3); ethylbenzene was detected in two samples with a maximum reported concentration of 0.012 mg/kg (DS-2-5); and total xylenes concentrations were detected in two samples with the maximum reported concentration of 0.12 mg/kg (DS-2-5). Benzene, methyl tert-butyl ether (MTBE), and tert-butanol (TBA) were not detected above the laboratory reporting limit(SECOR, 2006). Historical soil analytical results are provided in Appendix B. The locations of historical soil samples collected during previous Site assessment activities are shown on the figures provided in Appendix B. SCOPE OF WORK SECOR proposes to install two soil borings to 60 feet bgs in the vicinity of the #2 Dispenser(Figure 2). The two soil borings will serve to assess the lateral and vertical extent of hydrocarbon impact detected in soil samples collected beneath the #2 Dispenser on December 12, 2005. Proposed soil boring locations are shown on Figure 2. P:WRCO\OODesert Sites\5365WR5365(Wrkpin 06.06.06).doc.doc Mr. Howard H. Wines, III SECOR Job No. 08BP.05365.06 June 28, 2006 Page 3 Preliminary Field Activities All field activities will be conducted with safety as a foremost concern. A site-specific health and safety plan (HASP) will be prepared in accordance with 29 CFR 1910.120 to address the potential hazards involved with the proposed soil boring and soil sampling activities. All persons, including all other on-site subcontractors or regulatory personnel, will be required to familiarize themselves with and sign the HASP in an attempt to minimize safety hazards. Prior to drilling at the site, the proposed boring location will be marked and Underground Service Alert-South (USA), a California State-specific underground utility notification service, will be notified. Additionally, a private utility locator will be contracted to further evaluate and mark the locations of any potential subsurface underground utilities not identified by USA. All pre-field activities, including utility clearance will be conducted in accordance with Atlantic Richfield's Precautionary Procedures and Guidelines Document for Drilling, Subsurface Investigations and Remedial Construction Activities for GEM Retail Operations. Any applicable permits will be obtained from Kern County and the City of Bakersfield. Notifications will be made to the BFD, City of Bakersfield, and Atlantic Richfield at least five days prior to the initiation of work. Soil Boring Installation and Soil Sampling SECOR proposes to install two soil borings in the vicinity of the #2 Dispenser. Soil boring advancement activities will be conducted by a C57 licensed drilling contractor. Prior to drilling, all boring locations will be cleared using hand tools or air knife to a minimum depth of five feet bgs. Hollow-stem auger drilling equipment will be used to drill the soil borings. Soil borings will be advanced to a depth of 60 feet bgs. For logging, field screening, and soil analysis purposes, soil samples will be collected from each boring at five foot intervals to total depth explored. Qualified SECOR personnel working under the direct supervision of a State of California Professional Geologist will log the borings in general accordance with the Unified Soil Classification System, using visual and manual methods for parameters including odor, staining, color, grain size, and moisture content. Collected soil samples will be field screened for volatile organic compounds (VOCs) using a photo-ionization detector(PID). All soil samples collected for chemical analysis will be prepared in accordance with Environmental Protection Agency (EPA) Method 5035 using Encore samplers, or equivalent, and brass sample tubes, and placed in an ice-filled cooler for preservation. The soil samples will be transported under Chain-of-Custody (COC) protocol to an Atlantic Richfield-approved, California Department of Health Services(DHS)-certified laboratory for analysis. Laboratory Analysis Soil samples collected for chemical analysis will be relinquished under COC protocol to an Atlantic Richfield approved, DHS-certified laboratory for analysis. All soil samples will be analyzed for the presence of GRO using EPA Method 8015M and for BTEX; MTBE, ethyl tert butyl ether(ETBE), di- isopropyl ether(DIPE), tertiary amyl methyl ether(TAME), TBA, and ethanol in accordance with EPA Method 8260B. !Waste Disposal Soil cuttings generated during drilling activities will be contained in labeled 55-gallon Department of Transportation (DOT) approved steel drums and temporarily stored on-site. Upon receipt of soil PAARMOODesert Sites\5365\AR5365(Wrkpin 06.06.06).doc.doc Mr. Howard H.
