CSE proposes to advance six soil borings adjacent to the USTs and dispensers and analyze soil samples for gasoline hydrocarbons during this environmental assessment. The BEA is being performed in association with the purchase of the property by Mr. Munther Hawatmeh from BP West Coast Products LLC (BP). The BEA is intended to establish baseline environmental conditions to satisfy the due diligence requirements for the eligibility of the buyer to seek reimbursement as a B Class claimant from the SWRCB/UST Cleanup Fund (USTCF) for any potential future investigation and/or cleanup cost that may be required by the Bakersfield Fire Department.Hazardous Materials Division (BFDHMD). 1. PURPOSE AND SCOPE: The purpose of this work plan is to outline the methodology to be followed for the assessment of the potential gasoline hydrocarbons in the soil at the subject site. The proposed scope of work for this project includes the following major tasks: • develop a work plan and worker health and safety plan for the BEA at the ARCO AM/PM Mini Market No. 3090; • advance two slant-drilled soil borings to a depth of 40 fbg with bottom hole locations beneath the east and west ends of the UST cluster, and four slant-drilled soil borings with bottom hole locations with bottom hole locations beneath the east and west dispensers on the north and south dispenser islands; • analyze soil (samples for TPH as gasoline, BTEX, MTBE, TBA, DIPE, ETBE, TAME, EDB, and 1,2-DCA; and • prepare a Baseline Environmental Assessment Report documenting the drilling activities, sample results, data analysis, conclusions, and recommendations for any further action that may be necessary. 58 IE 1400 Easton Drive, Suite 132, Bakersfield, California 93309 (661) 325-4862 — Fax (661) 325-5126, eensenv @aol.eom x Mr. Munther Hawatmeh June 21, 2007- Page 2 2. SITE DESCRIPTION: ARCO AM/PM Mini Market No. 3090 is located at 3333 Union Avenue, Bakersfield, Kern County, California (see Figure 1 — Site Location Map). The site is located in northeast quarter of the northeast quarter of Section 19, Township 29 South, Range 28 East, Mount Diablo Base and Meridian. The site is zoned C-2 for medium commercial use by the City of Bakersfield Planning Department. Commercial businesses flank Union Avenue and 34th Street. The site is an approximately 0.9-acre parcel developed with the 2,750 square foot market building and the retail vehicle fueling facilities (see Figure 2 — Aerial Plot Plan). The retail vehicle fueling facility consists of four 10,000-gallon double-walled fiberglass USTs and four multiple product dispensers (MPDs) on two dispenser islands (see Figure 3 - Plot Plan). 3. SITE MAPS: Site maps are included as Figures 1 through 3. 4. TOPOGRAPHY, GEOLOGY, AND HYDROGEOLOGY: The site is located at an elevation of 440 feet above MSL, and the topography slopes to the west, toward the ancient Kern and Buena Vista lakes (see Figure 1). The subject site is located on the eastern flank of the San Joaquin Valley and west of the southern Sierra Nevada. The surface of the San Joaquin Valley is composed primarily of unconsolidated Pleistocene (1.6 million to 11,000 years ago) and Recent (11,000 years ago to the present) alluvial sediments. Beneath the alluvial sediments are older, predominantly lake-bed deposits. These lie unconformably on Mio-Pliocene marine sediments, which extend to a crystalline basement at a depth of approximately 20,000 fbg. At the subject site, surface deposits consist of Quaternary (recent) unconsolidated alluvium overlying Quaternary (Pleistocene) nonmarine sediments. Geologic deposits in the study area include Pleistocene alluvial sediments that form a homocline dipping gently to the west-southwest. The deposits are alluvium consisting of indurated and dissected fan deposits (California Division of Mines and Geology, 1965, Geologic Map of California, Bakersfield Sheet). The alluvium consists of silty sands and fine-grained to coarse-grained sands, with intervals of finer grained, sandy silts and minor development of clay overbank deposits. Surface soils are classified by the Soils Conservation Services as Chanac loam with moderate permeability. The site is located in the southern portion of the San Joaquin Valley, with the Sierra Nevada Mountains 10 miles to the east, the San Emigdio Mountains 30 miles to the south, and the Temblor Mountains 40 miles to the west. In the region of the Kern Bluff Oil Field, the Tertiary, sedimentary sequence from top to bottom is non-marine Quaternary and Pleistocene Kern River Formation alluvium, marine Pliocene San Joaquin and Etchegoin formations, marine Upper Miocene Reef Ridge Formation, marine Middle Miocene Fruitvale Formation, marine Lower Miocene Round Mountain, Olcese, and Freeman-Jewett formations, marine Oligocene Vedder Formation, and marine Eocene Tumey and Kreyenhagen formations. The subject site is in an area of extensive plio-pleistocene faulting. These include the San Andreas Fault, 50 miles to the west. Oil is produced in faulted traps within the Kern Bluff Oil Field. Mr. Munther Hawatmeh June 21, 2007 - Page 3 The site is located in the southern portion of the Great Valley geomorphic province. The Great Valley is a north-south-trending valley, approximately 400 miles long by 50 miles wide, the southern portion of which is known as the San Joaquin Valley. Surface water and groundwater in the San Joaquin Valley are derived predominantly from the Sierra Nevada to the east and are transported by five major rivers, the closest to the site being the Kern River. The Kern River is located approximately one mile north of the site. The concrete-lined East Side and Kern Island canals are located 200 feet west of the site. The depth to the regional, unconfined aquifer is in excess of 150 fbg, and the groundwater gradient is to the southwest, toward the ancient Kern and Buena Vista lake beds (Kern County Water Agency (KCWA), 2005, 2003 Water Supply Report, May 2005). Perched groundwater at depths as shallow as 20 fbg is known to be present flanking the current course of the Kern River, one mile north of the site, but is not known to extend to the site (KCWA, 2005). No water wells are located on the site. There are several municipal water supply wells within a mile of the site. The groundwater is considered to be potable and suitable for beneficial uses. 5. TANK HISTORY: The site was developed in 1950 as a Standard Oil Company (Chevron) Service Station. The site was acquired by ARCO in 1973 and was redeveloped with the installation of two 10,000-gallon single-walled steel USTs, one 8,000-gallon single-walled steel UST, and nine single product dispensers (SPDs) on three dispenser islands. In 1988 the southern dispenser island was removed. In 1993, the fueling facilities were replaced by the four 10,000-gallon double-walled fiberglass USTs, four MPDs on two dispenser islands, and double-walled fiberglass product pipelines, which are present today(see Figure 3). 6. PREVIOUS WORK: In 1988 a petroleum release was discovered in association with remodeling of the dispensing facilities to remove the third (southern) dispenser island. TPH as gasoline and benzene were detected at maximum concentrations of 875 mg/kg and 32.55 mg/kg, respectively, in soil sample B-1-2', collected from 2 feet below the western SPD on the southern dispenser island. Based upon the laboratory results of the soil samples collected from beneath the SPDs, the Kern County Department of Environmental Health Services (KCDEHS) issued an Unauthorized Release Report (URR), dated April 41 1988, and required the performance of subsurface investigation activities (see Attachment 1 for a Summary of Previous Work). During 1989 and 1990, four soil borings were drilled to a maximum depth of 20 fbg in and around the area of the western SPDs on the central and southern dispenser island. TPH as gasoline and benzene were detected at maximum concentrations of 604 mg/kg and 0.67 mg/kg, respectively, in soil sample TB-3-10', collected from a depth of 10 fbg in the soil boring drilled adjacent to the western SPD on the central dispenser island. Based upon the results of a risk assessment that indicated a depth to groundwater of approximately 200 fbg, the KCDEHS issued the site a No Further Action (NFA) determination in its letter dated February 14, 1991. There is no record that cleanup activities were performed in association with this petroleum release (see Attachment 1). Mr. Munther Hawatmeh June 21, 2007- Page 4 In 1993 the fueling facilities were entirely replaced with the installation of the four 10,000-gallon double-walled fiberglass USTs, four MPDs on two dispenser islands, and double-walled fiberglass product pipelines, which are currently present. TPH as gasoline and benzene were detected at maximum concentrations of 11,000 mg/kg and 24 mg/kg, respectively, in soil sample T3E-2', collected from 2 feet below the invert at the eastern end of the southern UST. Based upon the laboratory results of the soil samples, the BFDHMD issued a second URR, dated August 12, 1993, and required the performance of additional subsurface investigation activities (see Attachment 1). From 1993 through 1995, ten soil borings were drilled to a maximum depth of 90 fbg in and around the area of the former USTs. TPH as gasoline was detected at a maximum concentration of 6,300 mg/kg in soil sample B-6-15', collected from a depth of 15 fbg in the soil boring drilled adjacent to the eastern end of the southern UST and benzene was detected at a maximum concentration of 10 mg/kg in soil sample B-10-55', collected from a depth of 55 fbg in the soil boring drilled adjacent to the eastern end of the southern UST. TPH as gasoline and BTEX were detected to a maximum depth of 80 fbg in the ten soil borings. Based upon the results of a second risk assessment, the BFDESD issued the site a NFA determination in its letter dated November 14, 1995. There is no record that cleanup activities were performed in association with the second petroleum release (see Attachment 1). Because the service station is within 1,000 feet of a public water well, an Enhanced Leak Detection (ELD) test was performed in September 2004 to evaluate both the liquid and vapor tightness of the fueling facilities. The secondary containment for two of the four USTs failed the ELD and a third URR was filed on September 27, 2004. Repairs were made to the secondary containment and the site passed an ELD retest. There are no records that BFDHMD has required the performance of any subsurface investigation or cleanup activities in association with this URR (see Attachment 1). Based upon the previous soil sampling, TPH as gasoline and benzene were detected at maximum concentrations of 875 mg/kg and 32.55 mg/kg, respectively, in the area of the dispenser islands and 11,000 mg/kg and 24 mg/kg, respectively, in the area of the former USTs, with TPH as gasoline and BTEX detected to a maximum depth of 80 fbg. There are no records of cleanup activities being performed, no records that soil samples have been analyzed for MTBE or other oxygenates and lead scavengers, and no records of any drilling and soil sampling being performed in the vicinity of the four existing USTs, which were installed in 1993. 7. STRATEGY AND PROCEDURES FOR CONDUCTING A BASELINE ENVIRONMENTAL ASSESSMENT: The intent of this work plan is to present the methodologies to be used to conduct a BEA at the subject site. CSE proposes to accomplish this by drilling six soil borings (B-1 through B-6) and analyzing soil samples for TPH as gasoline, BTEX, MTBE, TBA, DIPE, ETBE, TAME, EDB, and 1,2-DCA(see Figure 3 for the proposed soil boring locations). M' Mr. Munther Hawatmeh June 21, 2007 - Page 5 8. DESCRIPTION OF WORK TO BE PERFORMED: Prior to any intrusive methods being conducted at the site, Dig Alert(800-642-2444)will be utilized to map out the underground structures. Based on the clearances obtained, CSE will site the soil borings in safe locations. Drilling A total of six soil borings will be advanced during this BEA. Two soil borings (B-1 and B-2) will be slant-drilled to 40 fbg to bottom hole locations beneath the east and west ends of the fuel tank cluster and four soil borings (B-3 through B-6) will be slant-drilled to 20 fbg to bottom hole locations beneath the east and west MPDs on the two dispenser islands (see Figure 3). Soil samples will be collected at 5-foot intervals. During the drilling process, soil cuttings, as well as each soil sample, will be field- screened for VOCs using a PID calibrated to 100 ppmv isobutylene, and observations will be made for the visual identification of any soil staining or discoloration. Soils will be classified according to the Unified Soil Classification System by an experienced environmental geologist under the direct supervision of a State of California registered geologist, and all data will be recorded on logs of exploratory borings. Soil samples will be wrapped in Teflon TM, followed by close-fitting plastic caps, and held at a temperature of 4°C while in the field and in transit to the laboratory. Soil sampling equipment will be decontaminated between sampling attempts using a non-phosphate, soap and water wash; a tap-water rinse; and a distilled, deionized water rinse. Upon the completion of drilling the soil borings will be backfilled with cement and bentonite grout and the asphalt surface patched (see Attachment 2 for the Soil Boring and Sampling Procedures). Chemical Analysis of Samples The soil sample from each soil boring exhibiting the highest concentration through field screening using the PID will be submitted for laboratory analysis. The samples will be submitted to a California certified laboratory where they will be analyzed for TPH as gasoline using EPA Method 8015 (M), and BTEX, MTBE, TBA, DIPE, ETBE, TAME, EDB, and 1,2-DCA using EPA Method 82608. Report Preparation Upon completion of the'site assessment activities, a BEA Report will be prepared, which will be sent to BFDHMD and BP. The report will contain a summary of the sampling activities, required permits, a site map showing sample locations, description of methodologies used, certified laboratory reports and chain-of-custody documents, conclusions, and recommendations. 9. EQUIPMENT DECONTAMINATION PROCEDURES: Sampling equipment will be decontaminated using a non-phosphate, soap and water wash; a tap water rinse; and a distilled, deionized water rinse. The drill augers will be pressure washed between sampling locations. Plastic sheeting will be placed beneath the drill rig during drilling activities to prevent hydraulic fluids and lubricants from impacting the surface at the site. The contractor shall clean rigs, equipment, tools, and materials before leaving 1 * Mr. Munther Hawatmeh June 21, 2007 - Page 6 the work area to such a degree that will prevent site-derived materials from spreading outside of the work area. 10. WASTE DISPOSAL PROCEDURES: All drill cuttings and sample spoils that exhibit discoloration, odors, or elevated field-screening readings will be segregated and containerized in 55-gallon, Department of Transportation (DOT) - approved drums pending laboratory analytical results. Uncontaminated soil cuttings will be used as grading fill at the site. Munther Hawatmeh will arrange for the rinsate and impacted drill cuttings to be disposed of off-site at an appropriate licensed facility. 11. EMERGENCY OR INTERIM CLEANUP: Not applicable. 12. WORK SCHEDULE: Work will begin within 5 days subsequent to the acceptance of this work plan by the BFDHMD. The BFDHMD will be notified at least 48 hours before any on-site work commences. A Baseline Environmental Assessment Report will be submitted to the BFDHMD approximately 30 days after commencement of the work. 13. SITE SAFETY PLAN: A worker health and safety plan developed by CSE for UST site investigations outlines the procedures for conducting all on-site work. Site-specific information is provided on the cover page of the worker health and safety plan (see Attachment 3 for the Worker Health and Safety Plan). All work will be conducted in accordance with all regulatory requirements as defined by the California State Water Resources Control Board's LUFT Field Manual and the BFDHMD guidance documents.

SOIL BORING AND SAMPLING PROCEDURES CENTRAL SIERRA ENVIRONMENTAL, LLC'S STANDARD OPERATING PROCEDURES FOR SOIL BORING AND SAMPLING PROCEDURES PRE-DRILLING PROTOCOL Prior to the start of drilling, necessary permits, site access agreements, and/or encroachment permits are obtained. "As-built" 'drawings are obtained if possible. At least 48 hours prior to drilling, Underground Service Alert or an equivalent utility notification service is notified. A geophysical survey may be conducted. to locate subsurface utilities. Site plans and/or "as-built" drawings are compared to actual conditions observed at the site. The property owner/retailer is interviewed to gain information about locations of former UST systems (including dispensers, product lines, and vent lines). A visual inspection is made of the locations of the existing UST'system, and scars and patches in pavement are noted. The emergency shut-off switch is located for safety purposes. The critical zone, which is defined as 10 feet from any part of the UST system, is identified, and any proposed drilling locations within the critical zone may be subject to special hole clearance techniques. Drilling locations within the critical zone are avoided if possible. Notifications are made at least 2 weeks in advance of drilling to the property owner, client representative, on-site facility manager, regulatory agency, and/or other appropriate parties. A site-specific, worker health and safety plan for the site is available on site at all times during drilling activities. Prior to commencing drilling, a health and safety meeting is held among all on-site personnel involved in the drilling operation, including subcontractors and visitors, and is documented with a health and safety meeting sign-in form. A traffic control plan is developed prior to the start of any drilling activities for both on-site and off-site drilling operations. The emergency shut-off switch for the service station is located prior to the start of the drilling activities. A fire extinguisher and "No Smoking" signs (and Proposition 65 signs in California) are present at the site prior to the start of the drilling activities. The first drilling location is the one located furthest from any suspected underground improvements in order to determine the natural subsurface conditions, to be able to better recognize fill conditions, and to prevent cross contamination. For monitoring wells, a 2 x 2-foot square or 2-foot diameter circle is the minimum removal. For soil borings and push-type samplers, the minimum pavement removal is 8-inches. When pea gravel, sand, or other non-indigenous material is encountered, the drilling location will be abandoned unless the absence of subsurface facilities can be demonstrated and client approval to proceed is obtained. If hole clearance activities are conducted prior to the actual day of drilling, the clearance holes are covered with plates and/or backfilled. The minimum hole clearance depths are 4 feet below grade (fbg) outside the critical zone and 8 fbg within the critical zone and are conducted as follows: • 0 to 4 fbg: The area to be cleared exceeds the diameter of the largest tool to be advanced and is sufficiently large enough to allow for visual inspection of any obstructions encountered. The first 1 to 2 feet is delineated by hand digging to remove the soil, then the delineated area is probed to ensure that REVISED 3/29/02 ' LSE's Standard Operating Procedures for Soil Boring and Sampling Procedures Page 2 no obstructions exist anywhere near the potential path of the drill auger or push-type sampler. Probing is extended laterally as far as possible. Hand augering or post-hole digging then proceeds, but only to the depth that has been probed. If subsurface characteristics prohibit effective probing, a hand auger is carefully advanced past the point of probing. In this case, sufficient hand augering or post-hole digging is performed to remove all the soil in the area to be delineated. For soil borings located outside of the critical zone, an attempt should be made to probe an additional 4 feet. • 4 to 8 fbg: For the soil borings located inside the critical zone, probing and hand clearing an additional 4 feet is performed. If probing is met with refusal, then trained personnel advance a hand auger without excessive force. An alternate or additional subsurface clearance procedures may also be employed,-as required by clients, permit conditions, and/or anticipated subsurface conditions (for example, near major utility corridors or in hard soils). Alternate clearance techniques may include performing a geophysical investigation or using an air knife or water knife. If subsurface conditions prevent adequate subsurface clearance, the drilling operation is ceased until the client approves a procedure for proceeding in writing. If any portion of the UST system is encountered, or if there is any possibility that it has been encountered, the work ceases, and the client is notified immediately. If there is reason to believe that the product system has been damaged, the emergency shut-off switch is activated. The client will decide if additional uncovering by hand is required. If it is confirmed that the UST system has been encountered, tightness tests are performed. The hole is backfilled only with client approval. DRILLING AND SOIL SAMPLING PROCEDURES Soil boring are drilled using one of the following methods: • Manual drilling: Manual drilling utilizes a 2-inch-OD, hand auger manufactured by Xitech Industries, Art's Manufacturing Company, or similar equipment. Soil samples are collected with a drive sampler, which is outfitted with 1.5-inch by 3-inch steel or brass sleeves. The specific equipment used is noted on a soil boring log. • Truck-mounted, powered drilling: Truck-mounted, powered drilling utilizes hollow-stem flight auger drilling, air rotary drilling, or percussion hammer drilling, or similar technologies. Soil samples are collected in steel or brass sleeves with a California-modified, split-spoon sampler or, for specific projects, a continuous sampler. The specific equipment used is noted on a soil boring log. • Direct push sampling: Direct push sampling utilizes Geoprobes®, cone penetrometer testing rigs, or similar technologies. Soil samples are collected with a drive sampler, which is outfitted with steel or brass sleeves. The specific equipment used is noted on a soil boring log. REVISED 3/29/02 ' CSE's Standard Operating Procedures for Soil Boring and Sampling Procedures Page 3 Before each soil sampling episode, the sampling equipment is decontaminated using a non-phosphate soap wash, a tap-water rinse, and a deionized water rinse. The drill string is decontaminated with a steam cleaner between each soil boring (truck-mounted rigs). Soil samples that are collected in steel or brass sleeves are covered with aluminum foil or Teflon TM tape followed by plastic caps. If EPA Method 5035 is required, then 5 to 20 grams of soil is extracted from the sample and placed in methanol-preserved containers supplied by the laboratory, or sub samples are collected using Encore® samplers. During the drilling. process, soil samples and cuttings are field screened for VOCs using a photoionization detector calibrated to 100 parts per million by volume isobutylene. Any soil staining or discoloration is visually identified. Soils are classified according to the Unified Soil Classification System. Specific geologic and hydrogeologic information collected includes grading, plasticity, density, stiffness, mineral composition, moisture content, soil structure, grain size, degree of rounding, and other features that could affect contaminant transport. All data is recorded on a soil boring log under the supervision of a geologist registered in the state in which the site is located. The samples are labeled, sealed, recorded on a chain-of-custody record, and chilled to 4°C in accordance with the procedures outlined in the California State Water Resources Control Board's Leaking Underground Fuel Tank Field Manual and the Arizona Department of Environmental Quality's Leaking Underground Storage Tank Site Characterization Manual. Sample preservation, handling, and transportation procedures are consistent with Central Sierra Environmental, LLC's quality assurance/quality control procedures. The samples are transported in a chilled container to a state-certified, hazardous waste testing laboratory. Cuttings from the, soil borings are stored in 55-gallon, Department of Transportation (DOT)-approved drums, roll-off bins, or other appropriate containers, as approved by the client. Each container is labeled with the number of the soil boring(s) from which the waste was derived, the date the waste was generated, and other pertinent information. The drums are stored at the site of generation until sample laboratory analytical results are obtained, at which time the soil is disposed of appropriately. A soil boring log is completed for each soil boring and includes the following minimum information: • date of drilling; • location of soil boring; • project name and location; soil sample names and depths; • soil descriptions and classifications; • standard penetration counts (rigs); • photoionization detector readings; • drilling equipment; • soil boring diameter; • sampling equipment; REVISED 3/29/02 • CSE's Standard Operating Procedures for Soil Boring and Sampling Procedures Page 4 • depth to groundwater in soil boring; • name of person performing logging; • name of supervising registered geologist; and • name of drilling company (rigs and direct push). SOIL BORING COMPLETION PROCEDURES All soil borings are either properly abandoned or completed as a well. Abandonment Each soil boring that is not completed as a well is backfilled with bentonite grout, neat cement, concrete, or bentonite chips with a permeability less than that of the surrounding soils, and/or soil cuttings, depending on local, regulatory requirements or client instructions. Grout is placed by the tremie method. Backfilling is performed carefully to avoid bridging. The type of backfill material is noted on the soil boring log. Well Installation Wells are designed according to applicable state and local regulations as well as project needs. Details of the well design and construction are recorded on the soil boring log_and include the following minimum information (in addition to the items noted above for soil borings): • detailed drawing of well; • type of well (groundwater, vadose, or air sparging); • casing diameter and material; • screen slot size; • well depth and screen length (±1 foot); • filter pack material, size, and placement depths; • annular seal material and placement depths; • surface seal design/construction; • well location (±5 feet); and • well development procedures. Groundwater monitoring wells are generally designed with 30 feet of slotted casing centered on the water table, unless site conditions, project needs, or local regulations dictate a different well design. The sand pack is placed at least two feet above the top of the screen, and at least 3 feet of low permeability seal material is placed between the sand pack and the surface seal. The sand pack and low permeability seal material are placed in the annular space from the bottom up using the tremie method. When drilling in asphalt, a 24-inch round cut is made for the well pad. When drilling on concrete, a 2 x 2-foot square is sawcut. The well cover is traffic-rated and has a white lid with a black triangle painted on it (3 inches per side) or a black lid with a white triangle (3 inches per side). The completed well pad should is concrete of matching color with the existing surface. The well number is labeled on the outside of the well box/pad REVISED 3/29/02 • LSE's Standard Operating Procedures for Soil Boring and Sampling Procedures Page 5 and the inside of the well box. The number on the outside is painted on with a stencil, stamped, or attached to the well with a metal plate. The number on the inside is written on the well cap with waterproof ink. The casing has a notch or indication on its north side indicating a unique measuring/surveying point. Well development is conducted by simple pumping if bridging of the screen does not occur. If bridging occurs, well surging is conducted for adequate well production. Well surging is created by the use of surge blocks, bailers, or pumps, whichever method is most appropriate for the well use. Only formation water is used for surging the well. Well development continues until non-turbid groundwater is produced or turbidity stabilizes. All purged groundwater is held on site in covered 55-gallon DOT-approved drums or other appropriate containers until water sample analytical results are received. The elevation of the north side of the top of well casing (or other appropriate reference point from which the depth to groundwater can be measured) is surveyed to an accuracy of±0.01 foot. All measurements are reproduced to assure validity. Surveying is performed by a state-licensed surveyor if required by state or local regulations. In the State of California, wells are surveyed in accordance with AB2886. DATA REDUCTION The data compiled from the soil borings is summarized and analyzed. A narrative summary of the soil characteristics is also presented. The soil boring logs are checked for the following information: • correlation of stratigraphic units among borings; • identification of zones of potentially high hydraulic conductivity; • identification of the confining layer; • indication of unusual/unpredicted geologic features (fault zones, fracture traces, facies changes, solution channels, buried stream deposits, cross-cutting structures, pinchout zones, etc.); and • continuity of petrographic features such as sorting, grain-size distribution, cementation, etc. Soil boring/well locations are plotted on a properly scaled map. If appropriate, soil stratigraphy of the site is presented in a scaled cross section. Specific features that may impact contaminant migration, e.g., fault zones or impermeable layers, are discussed in narrative form and supplemented with graphical presentations as deemed appropriate.

Site-specific information is provided on the cover page to this document. This worker health and safety plan was developed by CSE's through consultation of the following documents: • OSHA 29 CFR 1910 - "Hazardous Waste Operations and Emergency Response, Final Ruling," March 1989; • NIOSH/OSHA/USCG/EPA "Occupational Safety and Health Guidance Manual for Hazardous Waste Site Activities," October 1985; and • CSE's Corporate Health and Safety Program. This worker health and safety plan is divided into the following categories: 1. Job Hazard Assessment; 2. Exposure Monitoring Plan; 3. Personal Protective Equipment; 4. Work Zones and Security Measures; 5. Decontamination and Disposal; 6. Employee Training; and 7. Emergency Procedures. 1.JOB HAZARD ASSESSMENT Immediate tasks at petroleum release sites include an evaluation of any present or potential threat to public safety. Questions need to be answered regarding the dangers of significant vapor exposures and potential explosion hazards. Potential Chemical Hazards The chemical components of gasoline that are the most dangerous to site workers are the volatile aromatics, benzene, toluene, ethylbenzene, xylene, and potentially, organic lead (see Appendix 1 for Material Safety Data Sheet). Additionally, solvents such as 1,2-dichlorobenzene and 1,2-dichloroethane may also be used as cleaning solutions at service stations. The primary health risks associated with each of these chemicals are described below. • I Worker Health and Safety Plan Page 2 Gasoline - Suspected human carcinogen. A TLV of 300 ppm or 900 mg/m3 has been assigned to gasoline. This value of 300 ppm was assigned based on an average of 3 percent benzene (10 ppm TLV) in gasoline. Low-level inhalation exposure to gasoline can cause irritation to the eyes, nose, and respiratory system; headache; and nausea. Benzene Suspected human carcinogen. A TLV of 10 ppm or 30 mg/m3 has been assigned to benzene. Benzene has a low odor threshold limit of 1.4 ppm. Low-level inhalation exposure to benzene can cause irritation to the eyes, nose, and respiratory system; headache, and nausea. Toluene - A TLV OF 100 ppm or 375 mg/m3 has been assigned to toluene. Toluene has a low odor threshold limit of 2.1 ppm. Low-level inhalation exposure to toluene can cause fatigue, weakness, confusion, and euphoria. Ethvlbenzene -A TLV of 100 ppm or 435 mg/m3 has been assigned to ethylbenzene. Ethylbenzene has a low odor threshold limit of 2 ppm. Low-level inhalation exposure to ethylbenzene can cause irritation to the eyes and mucous membranes. Xylene - A TLV or 100 ppm or 435 mg/m3 has been assigned to xylene. No low odor threshold limit has been established for xylene. Low-level inhalation exposure to xylene can cause dizziness, excitement, and drowsiness. 1,2-Dichlorobenzene - A TLV of 50 ppm or 306 mg/m3 has been assigned to 1,2-dichlorobenzene. 1,2-dichlorobenzene has a low odor threshold limit of 4.0 ppm. Acute vapor exposure can cause coughing, dizziness, and drowsiness. It may cause skin irritation. 1,2-Dichloroethane - A TLV of 200 ppm. No data is available concerning odor threshold. Acute vapor exposure can cause coughing, dizziness, drowsiness, and skin irritation. Tetraethyl Lead -A TLV of 0.1 mg/m3 has been assigned to tetraethyl lead. Tetraethyl lead is a colorless or red-dyed liquid at atmospheric conditions. No data is available concerning odor threshold. Acute vapor exposure can cause insomnia, delirium, coma, and skin irritation. Potential Physical Hazards Trenching - Dangerously high fuel vapor levels will be monitored using an LEL meter. The presence of underground utilities are also of concern, and Underground Service Alert will be notified in advance of any trenching work for identification of all underground utilities in the immediate area. Worker Health and Safety Plan Page 3 Drilling - Dangerously high fuel vapor levels will be monitored using an LEL meter. The presence of underground utilities are also of concern, and Underground Service Alert will be notified in advance of any drilling work for identification of all underground utilities in the immediate area. Sampling - Use of personal protective equipment will minimize the potential for exposure of personnel conducting site investigation activities. Heat stress will be monitored by each individual and controlled through regular work breaks as outlined in the American Conference of Governmental Industrial Hygienists' TLV's for heat stress conditions. 2. EXPOSURE MONITORING PLAN Potential exposure hazards found at fuel storage tank sites primarily include toxic airborne vapors from the petroleum release. The most dangerous airborne vapor likely to be encountered during a fuel storage tank investigation is benzene. Gasoline vapor concentration levels will be monitored in the breathing zone with a PID calibrated to benzene. When the action level of 150 ppm (one half the TLV of gasoline) is detected in the breathing zone, respiratory protection will be required utilizing full-face or half-face respirators with organic vapor cartridges. Monitoring for combustible gases will also be performed using an LEL meter when vapor concentrations above 2,000 ppm are detected with the PID. The action level is 35 percent of the LEL for gasoline vapors or 4,500 ppm. If this level is attained or exceeded, the work party will be IMMEDIATELY withdrawn. 3. PERSONAL PROTECTIVE EQUIPMENT The level of protection during the site investigation will usually be level "D." Level D protective equipment includes coveralls, safety boots, safety glasses, gloves, and hard hats if drilling or trenching operations are in progress. Upgrading the protection level would be based on airborne benzene concentration levels equal to or exceeding the action level. An upgrade to level "C" protection would be required if the action level is equaled or exceeded. Additional equipment required for level C would be a full-face or half-face air purifying canister-equipped respirator and TyvekTM suits with taped arm and leg seals. If the action level is met or exceeded (35 percent) for the LEL, work will cease until the vapor level is measured to be below 20 percent of the LEL. r Worker Health and Safety Plan Page 4 A fire extinguisher will be maintained on site. Decisions for workers' safety are based on a continual evaluation of existing or changing conditions. 4. WORK ZONES AND SECURITY MEASURES To facilitate a minimum exposure to dangerous toxic vapors and/or physical hazards, only authorized persons will be allowed on the job site. Work zones will be defined by CSE staff who will also be responsible for maintaining security within these zones. Only the minimum number of personnel necessary for the fuel storage tank investigation will be present in the work zone. 5. DECONTAMINATION AND DISPOSAL CSE's standard operating procedures establish practices that minimize contact with potentially contaminated materials. Decontamination procedures are utilized if there is suspected or known contamination of equipment, supplies, instruments or any personnel surfaces. Soap and water will be utilized to remove contaminants from personnel surfaces as well as equipment and instruments. Contaminated wash water will be disposed of in accordance with procedures outlined in the LUFT guidance documents. 6. EMPLOYEE TRAINING All CSE employees working on the site will have had, at a minimum, the required 40-hour OSHA Training for Hazardous Waste Site Activities (29 CFR 1910, 120), which includes training in the use of personal protective equipment. Individualized respirator fit testing is required of all CSE employees working at the site. 7. EMERGENCY PROCEDURES CSE employees are trained in emergency first aid, and emergency first aid provisions will be brought to the site. In the event of overt personnel exposure (i.e., skin contact, inhalation, or ingestion), the victim will be transported to and treated at the closest hospital (see Hospital Map). A 911 call will dispatch EMT's to the scene of the injury. If warranted by the severity of the injury, EMT's would summon an air ambulance. r APPENDIX 1. MATERIAL-SAFETY DATA SHEET r i APPENDIX 1.

Eye contact with the vapors, fumes, or spray mist from this substance could also cause similar signs and symptoms. SKIN: Contact with the skin causes irritation. Not expected to be harmful to internal organs if absorbed through the skin. Prolonged or frequently repeated contact may cause the skin to become cracked or dry from the defatting action of this material. INGESTION: Because of the low viscosity of this substance, it can directly enter the lungs if it is swallowed (this is called aspiration). This can occur during the act of swallowing or when vomiting the substance. Once in the lungs, the substance is very difficult to remove and can cause severe injury to the lungs and death. INHALATION: May be harmful if inhaled. Breathing the vapors at concentrations above the recommended exposure standard can cause central nervous system effects. The vapor or fumes from this material may cause respiratory irritation. SIGNS AND SYMPTOMS OF EXPOSURE: Eye damage or irritation: may include pain, tearing, reddening, swelling, and impaired vision. Skin injury:.may include pain, discoloration, swelling, and blistering. Respiratory irritation: may include coughing and difficulty breathing. Central nervous system effects may include headache, dizziness, nausea, vomiting, weakness, loss of coordination, blurred vision, drowsiness, confusion, or disorientation. At extreme http://library.cbest.chevron.com/lubes/chevmsd.../33ef0475182faded8825661f005d73f6?OpenDocument(5 of 18) [11/26/2001 6:29:42 PM] Ch6ron Plus Unleaded Gasoline MSDS#3205 Rev#23(12/08/00) exposures, central nervous system effects may include respiratory depression, tremors or convulsions, loss of consciousness, coma or death. CARCINOGENICITY: Risk depends on duration and level of exposure. See Section 11 for additional information. Gasoline has been classified as a Group 2B carcinogen (possibly carcinogenic to humans) by the International Agency for Research on Cancer (IARC). Contains chemical(s) known to the State of California to cause cancer. Contains benzene, which has been classified as a carcinogen by the National Toxicology Program (NTP), and a Group 1 carcinogen (carcinogenic to humans) by the International Agency for Research on Cancer (IARC). Contains ethylbenzene which has been classified as a Group 2B carcinogen (possibly carcinogenic to humans) by the International Agency for Research on Cancer (IARC). Whole gasoline exhaust was reviewed by the International Agency for Research on Cancer (IARC) in their Monograph Volume 46 (1989). Evidence for causing cancer was considered inadequate in animals and inadequate in humans. IARC placed whole gasoline exhaust in Category 213, considering it possibly carcinogenic to humans. 4. FIRST AID MEASURES EYE: Flush eyes with water immediately while holding the eyelids open. Remove contact lenses, if worn, after initial flushing, and continue flushing for at least 15 minutes. Get medical attention if irritation persists. SKIN: Wash skin immediately with soap and water and remove contaminated clothing and shoes. Get medical attention if irritation persists. Discard contaminated clothing and shoes or thoroughly clean before reuse. INGESTION: If swallowed, give water or milk to drink and telephone for medical advice.

HANDLING AND STORAGE This product presents an extreme fire hazard. Liquid very quickly evaporates, even at low temperatures, and forms vapor (fumes) which can catch fire and burn with explosive violence. Invisible vapor spreads easily and can be set on fire by many sources such as pilot lights, welding equipment, and electrical motors and switches. Electrostatic charge may accumulate and create a hazardous condition when handling this material. To minimize this hazard, bonding and grounding may be necessary but may not, by themselves, be sufficient. Review all operations which have the potential of generating an accumulation of electrostatic charge and/or a flammable atmosphere (including tank and container filling, splash filling, tank cleaning, sampling, gauging, switch loading, filtering, mixing, agitation, and vacuum truck operations) and use appropriate mitigating procedures. For more information, refer to OSHA Standard 29 CFR 1910.106, "Flammable and Combustible Liquids", National Fire Protection Association (NFPA) 77, "Recommended Practice on Static Electricity", and/or the American Petroleum Institute (API) Recommended Practice 2003, "Protection Against Ignitions Arising Out of Static, Lightning, and Stray Currents". Improper filling of portable gasoline containers creates danger of fire. Only dispense gasoline into approved and properly labeled gasoline containers. Always place portable containers on the ground. Be sure pump nozzle is in contact with the container while filling. Do not use a nozzle's lock-open device. Do not fill portable containers that are inside a vehicle or truck/trailer bed. Never siphon gasoline by mouth. Use only as a motor fuel. Do not use for cleaning, pressure appliance fuel, or any other such use. DO NOT USE OR STORE near heat, sparks or open flames. USE AND STORE ONLY IN WELL VENTILATED AREA. Keep.container closed when not in use. READ AND OBSERVE ALL PRECAUTIONS ON PRODUCT LABEL. Container is not designed to contain pressure. Do not use pressure to empty container or it may rupture with explosive force. Empty containers retain product residue (solid, liquid, and/or vapor) and can be dangerous. http://Iibrary.cbest.chevron.com/lubes/chevmsd.../33ef0475182faded8825661f005d73f6?OpenDocument(8 of 18)[11/26/2001 6:29:42 PM] • Chevron Plus Unleaded Gasoline MSDS#3205 Rev#23(12/08/00) Do not pressurize, cut, weld, braze, solder, drill, grind, or expose such containers to heat, flame, sparks, static electricity, or other sources of ignition. They may explode and cause injury or death. Empty containers should be completely drained, properly closed, and promptly returned to a drum reconditioner, or properly disposed of. 8. EXPOSURE CONTROLS/PERSONAL PROTECTION GENERAL CONSIDERATIONS: Consider the potential hazards of this material (see Section 3), applicable exposure limits,job activities, and other substances in the work place when designing engineering controls and selecting personal protective equipment. If engineering controls or work practices are not adequate to prevent exposure to harmful levels of this material, the personal protective equipment listed below is recommended. The user should read and understand all instructions and limitations supplied with the equipment since protection is usually provided for a limited time or under certain circumstances. ENGINEERING CONTROLS Use process enclosures, local exhaust ventilation, or other engineering controls to control airborne levels below the recommended exposure limits. PERSONAL PROTECTIVE EQUIPMENT EYE/FACE PROTECTION: No special eye protection is normally required. Where splashing is possible, wear safety glasses with side shields as a good safety. practice.

ACUTE ORAL EFFECTS: The oral LD50 in rats is > 5 ml/kg. ACUTE INHALATION EFFECTS: No product toxicology data available. ADDITIONAL TOXICOLOGY INFORMATION: http://Iibrary.cbest.chevron.com/lubes/chevmsd.../33ef0475182faded8825661f005d73f6?Open Document(10 of 18)[11/26/2001 6:29:42 PM] Chevron Plus Unleaded Gasoline MSDS#3205 Rev#23(12/08/00) When vapor exposures are low, or short duration and infrequent, such as during refuelling and tanker loading/unloading, neither total hydrocarbon nor components such as benzene are likely to result in any adverse health effects. In situations such as accidents or spills where exposure to gasoline vapor and liquid is potentially high, attention should be paid to potential toxic effects of specific components in addition to those of total hydrocarbons. Information about specific components in gasoline are found in Section 1 and Section 15 of this MSDS. More detailed information on the health hazard of specific gasoline components can be obtain from the Chevron Emergency Information Center (see Section 1 for telephone numbers). A study was done in which ten volunteers were exposed for 30 minutes to about 200, 500 or 1000 ppm concentrations of the vapor of three different unleaded gasolines. Irritation of the eyes was the only significant effect observed, based on both subjective and objective assessments. An inhalation study with rats exposed to 0, 400 and 1600 ppm of wholly vaporized unleaded gasoline, 6 hours per day on day 6 through 16 of gestation, showed no teratogenic effects nor indication of toxicity to either the mother or the fetus (sex ratio, embryotoxicity, fetal growth and development). An inhalation study with pregnant rats exposed to 0, 1000, 3000, and 9000 ppm of unleaded gasoline vapor, 6 hours per day on days 6 through 20 of gestation, showed no teratogenic effects nor indications of toxicity to either the mother or the fetus. In an inhalation study, groups of 6 Fischer rats (3 male, 3 female) were exposed to 2056 ppm of wholly vaporized unleaded gasoline for 6 hours per day, 5 day per week for up to 18 months. Histopathology of the peripheral nervous system and spinal cord revealed no distal axonal neuropathy of the type associated with exposure to n-hexane even though gasoline contained 1.9% n-hexane. The authors concluded that gasoline treatment may have amplified the incidence and prominence of some naturally occurring age related changes in the nervous system. Wholly vaporized unleaded gasoline was used in a 3 month inhalation study. Groups of 40 rats (20 males, 20 female) and 8 squirrel monkeys (4 male, 4 female) were exposed 6 hours per day and 5 days per week for 13 weeks to 384 or 1552 ppm gasoline. One group of each species served as unexposed controls. The initial conclusion of this study was that inhalation of gasoline at airborne concentrations of up to 1522 ppm caused no toxicity in rats or monkeys. However, further histopathological examination of male rat kidneys on the highest dose group revealed an increased incidence and severity of regenerative epithelium and dilated tubules containing http://Iibrary.cbest.chevron.com/lubes/chevmsd.../33ef0475182faded8825661f005d73f6?OpenDocument(11 of 18)(11/26/2001 6:29:42 PM] Chevron Plus Unleaded Gasoline MSDS#3205 Rev#23(12/08/00) proteinaceous deposits. Rabbits were exposed to unleaded gasoline 24 hour per day, 5 days per week for two weeks; 0, 2.5, 5 or 8 ml were applied to the skin under an occlusive dressing. Applied in such a way, this motor gasoline was corrosive to the rabbit skin and animals in all dose groups had decreased bodyweights. The slight and/or isolated systemic effects noted in the study were judged to be not significant. Unleaded gasoline was assayed for mutagenic and cytogenetic activity. Gasoline was not mutagenic, either with or without activation, in Ames assay (Salmonella typhimurium), Saccharamyces cerevisesae, or mouse lymphoma assays. In addition, point mutations were not induced in human lymphocytes exposed to gasoline in vivo. The gasoline was not mutagenic when tested in the mouse dominant lethal assay. Administration of gasoline to rats did not cause chromosomal aberrations in their bone marrow cells. In a lifetime skin painting study, 50 male Swiss mice were treated with 0.05 ml of unleaded gasoline three times per week. Positive control groups were treated with benzo(a)pyrene in acetone; an untreated negative control group was also included. The repeated exposure to gasoline caused severe skin irritation, ulceration, hyperkeratosis and abscesses. There was no statistically significant increase in the incidence of skin tumors. Histopathology at the end of the study showed that unleaded gasoline did not increase the incidence of tumors in other organs. Lifetime inhalation of wholly vaporized unleaded gasoline at 2056 ppm has caused increased liver tumors in female mice. The mechanism of this response is still being investigated but is thought to be an epigenetic process unique to the female mouse. This exposure also caused kidney damage and eventually kidney cancer in male rats. No other animal model studied has shown these adverse kidney effects and there is no physiological reason to believe that they would occur in man. EPA has concluded that the mechanism by which wholly vaporzied unleaded gasoline causes kidney damage is unique to the male rat. The response in that species (kidney damage and cancer) should not be used in human risk assessment. In their 1988 review of carcinogenic risk from gasoline, The Internatioal Agency for Research on Cancer (IARC) noted that, because published epidemiology studies did not include any exposure data, only occupations where gasoline exposure may have occurred were reviewed. These included gasoline service station attendants and automobile mechanics. IARC also noted that there was no opportunity to separate effects of combustion products from those of gasoline itself. Although IARC allocated gasoline http://library.cbest.chevron.com/lubes/chevmsd.../33ef0475182faded8825661f005d73f6?Open Document(12 of 18)[11/26/2001 6:29:42 PM] Ghelron Plus Unleaded Gasoline MSDS#3205 Rev#23(12/08/00) a final overall classification of Group 213, i.e. possibly carcinogenic to humans, this was based on limited evidence in experimental animals plus supporting evidence including the presence in gasoline of benzene and 1, 3-butadiene. The actual evidence for cacinogenicity in humans was considered inadequate. To explore the health effects of workers potentially exposed to gasoline vapors in the marketing and distribution sectors of the petroleum industry, the American Petroleum Institute sponsored a cohort mortality, a nested case-control, and an exposure assessment study. Histories of exposure to gasoline were reconstructed for a cohort of more than 18,000 employees from four companies for the time period between 1946 and 1985. Data were analyzed based on length of employment, length of exposure,job category, age at first exposure and estimated cumulative and peak exposures. Cumulative exposure was defined as the,sum of products of TWA exposure and duration of exposure of each job in an employee's work history. Amoung cohort members, cumulative exposure ranged from 2 to 8,000 ppm-years. In general, long-term drivers at small terminals had the highest exposures, and short-term workers with "other terminal jobs" had the lowest. A peak exposure was defined as an episode in excess of 500 ppm lasting 15 to 90 minutes. The results of the cohort study indicated that there was no increased mortality from either kidney cancer or leukemia among marketing and marine distribution employees who were exposed to gasoline in the petroleum industry, when compared to the general population. More importantly, based on internal comparisons, there was no association between mortality from kidney cancer or leukemia and various indices of gasoline exposure. For acute myeloid leukemia (AML), a non-significant mortality increase was found in land-based terminal employees, but no trend was detected when the data were analyzed by various gasoline exposure indices. This non-significant excess was limited to land-based terminal employees hired prior to 1948. On the other hand, a deficit of mortality from AML was observed among marine employees. In addition to the cohort study, a subsequent nested case-control study was also conducted. Four diseases were selected for analysis in the case-control study: Leukemia (all cell types), AML, kidney cancer and multiple myeloma. For each case, five individually matched controls were randomly selected from the cohort. In the original cohort study, broad generic job categories were used as part of exposure assessment. In the case-control study, a finer and more homogeneous job classification was developed. In addition to job category, several quantitative gasoline exposure indices were used in the case-control analysis: length of exposure, cumulative exposure (ppm-years in terms of total hydrocarbons) http://library.cbest.chevron.com/tubes/chevmsd.../33ef0475182faded8825661f005d73f6?OpenDocument(13 of 18)(11/26/2001 6:29:42 PM] T Chevron Plus Unleaded Gasoline MSDS#3205 Rev#23(12/08/00) and frequency of peak exposure. Time period of first exposure to gasoline (1948 or before and 1949 or after) was also included as an exposure index. Results of the nested case-control study confirmed the findings of the original cohort study. That is, exposure to gasoline at the levels experienced by this cohort of distribution workers is not a significant risk factor for leukemia (all cell types), acute myeloid leukemia, kidney cancer or multiple myeloma. 12. ECOLOGICAL INFORMATION ECOTOXICITY: Gasoline studies have been conducted in the laboratory under a variety of test conditions with a range of fish and invertebrate species. An even more extensive database is available on the aquatic toxicity of individual aromatic constituents. The majority of published studies do not identify the type of gasoline evaluated, or even provide distinguishing characteristics such as aromatic content or presence of lead alkyls. As a result, comparison of results among studies using open and closed vessels, different ages and species of test animals and different gasoline types, is difficult. The bulk of the available literature on gasoline relates to the environmental impact of monoaromatic (BTEX) and diaromatic (naphthalene, methylnaphthalenes) constituents. In general, non-oxygenated gasoline exhibits some short-term toxicity to freshwater and marine organisms, especially under closed vessel or flow-through exposure conditions in the laboratory. The components which are the most prominent in the water soluble fraction and cause aquatic toxicity, are also highly volatile and can be readily biodegraded by microorganisms. The 96-hour LC50 in rainbow trout (Oncorhynchus mykiss) is 2.7 mg/1 (BTEX). The 4&hour LC50 in daphnia (Daphnia magna) is 3.0 mg/1 (BTEX). The 96-hour LC50 in sheepshead minnow (Cyprinodon variegatus) is 8.3 mg/1 (BTEX). The 96-hour LC50 in mysid shrimp (Mysidopsis bahia) is 1.8 mg/l (BTEX). ENVIRONMENTAL FATE: Following spillage, the more volatile components of gasoline will be rapidly lost, with concurrent dissolution of these and other constituents into the water. Factors such as local environmental conditions (temperature, wind, mixing or wave action, soil type, etc), photo-oxidation, biodegradation and adsorption onto suspended sediments, can contribute to the weathering of spilled gasoline. The aqueous solubility of non-oxygenated unleaded gasoline, based on analysis of http://Iibrary.cbest.chevron.com/lubes/chevmsd.../33ef0475182faded8825661f005d73f6?Open Document(14 of 18)(11/26/2001 6:29:42 PM] Lhetron Plus Unleaded Gasoline MSDS#3205 Rev#23(12/08/00) benzene, toluene, ethylbenzene+xylenes and naphthalene, is reported to be 112 mg/l. Solubility data on individual gasoline constituents also available. 13. DISPOSAL CONSIDERATIONS Use material for its intended purpose or recycle if possible.

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 t • Preparation of this technical report. ' SITE INFORMATION ' The Site is located at 3333 Union Avenue in Bakersfield, California; at an elevation of approximately 440 feet above mean sea level. The Site is located on the southwest corner of Union Avenue and 34th Street. Local topography slopes to the south-southwest at approximately 0.02 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 275 feet east of the East Side Canal, 400 feet east of the Kern Island Canal, and 1.4 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 ttopography(KCWA, 1990) 1 Dispenser Secondary Containment Upgrade Report Atlantic Richfield Station No.3090 ' 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 27, 2005, Belshire completed the removal of all penetration fittings below.the dispensers and replaced them with PiciesTM pan entry fittings, as well as replacing both sump 89 and the turbine sumps with fiberglass sumps. 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. Steve Underwood. _ P Field activities were conducted in accordance with the procedures for soil sampling included in'Appendix B. t The dispenser sample locations are indicated.on Figure.3. This section 'summarizes the results of the soil sampling activities. ' Lead Agencies: Bakersfield Fire Department Permit No. MOD-0390 Agency Contact Name: Steve Underwood, Fire Prevention Officer (661) 326-3190 ' Number of Dispenser Samples: 8 Dispenser Sample Names: D-1-2, D-1-6, D-2-2, D-2-6, D-3-2, D-3-6, D-4-2, ' D-4-6, D-5-2, D-5-6, D-6-2, and D-6-6. 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—C;2) 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 eight soil samples were collected from beneath the dispensers. Detectable concentrations of ' petroleum hydrocarbon constituents above the laboratory reporting limit (RL) were identified in one of the eight 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, TBA, and ethanol were Dispenser Secondary Containment Upgrade Report , Atlantic Richfield Station No.3090 ' Bakersfield, California Page 3 not detected above the laboratory RL in any of the soil samples collected. GRO was detected in one ' sample at a concentration of 1,100 mg/kg (D-2-2), and total-xylenes were detected at a concentration of 61 mg/kg (D-2-2). The soil sample analytical'results are summarized in Table 1. A copy of the certified laboratory analytical reports and chain-of-custody documeritation 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 27, 2005, Belshire completed the removal of,all penetration fittings below the ' dispensers. A total 'of eight soil samples were collected from beneath the dispensers for confirmation purposes. Benzene; MTBE, TBA, and ethanol were not detected above the laboratory RL in any of the soil samples collected. GRO was detected in 'one sample at a concentration of 1,100 mg/kg (D-2-2), and total xylenes were detected.at a concentration of 61 mg/kg (D-2-2). • Following completion of the soil sampling and excavation activities, new PiciesTM pan entry fittings were installed below the dispensers. 'Belshire also replaced both sump 89.and the turbine sumps ' with fiberglass sumps: • Based on the discovered ..impact to subsurface soils, an Unauthorized Release Report was ' submitted by Atlantic Richfield.

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—C,Z) by EPA Test Method 8260B; 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 eight soil samples were collected from beneath the dispensers. Detectable concentrations of petroleum hydrocarbon constituents above the laboratory reporting limit (RL) were identified in one of the eight 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.

' 1.2 Site History . On May 6, 2008 RAM conducted soil sampling at the Fastri market and gas station located at 3501 Mt. Vernon, Bakersfield, California(Site), as noted in ' Figure 1,Area Map. Soil samples were taken from beneath piping that was being replaced. The sampling was conducted to assess the potential presence of petroleum hydrocarbons in soils beneath former piping at the station as the ' equipment was modified under Bakersfield Fire Department(BFD)Permit to Modify Underground Storage Facility,permit number MD0407. tAn excavation was developed to expose and replace piping leading from the underground storage tanks (USTs)to-ihe dispenser islands, as shown on Figure 3, ' Boring Locations and Analytical Results.- The underlying soils were sands, clays and gravels. Soil samples were taken under the direction of BFD from below the former piping at the ends and in the center of the piping run. The soil samples were collected from between 9 inches and 20 inches below the piping. It was not possible to obtain deeper samples due to the gravel in the soil, and the position of the piping above the UST's. A summary of soil sample analytical results is ' presented in Table.1 following the text, and on Figure 3.

Project#200370 Site Investigation Report ' November.2008 ' In the'soil sample collected from below the south end of the piping, hydrocarbons were detected in one.sample as follows. ' Sample 1-20"S Soil sample 1-20" S, collected from 20 inches-below the south end of the piping contained significant concentrations of benzene, toluene, ethylbenzene, xylenes ' and TPH-g. The key points of this sample's analytical'results are: 0 the concentration of benzene in the soil, 1,600 gg/Kg, exceeds the ' Preliminary Remediation Goals(PRG, EPA 2004)for industrial soil of 1,400 µg/Kg, • the concentrations of toluene, ethylbenzene, and xylenes did not exceed the ' 2004 PRG values, and 0 the concentration of TPH-g exceeds the LUFT value. No PRG value has been established for gasoline. A Site Investigation Workplan was submitted to BFD b RAM on Jul 18 2008. g p Y Y On August 25, 2008 BFD responded to the Site Investigation Workplan and ' requested a Revised Site Investigation Workplan to include a third boring to define the subsurface hydrocarbon plume. A Revised Site Investigation Workplan was submitted to the BFD on August 28; 2008. This Report presents the results of the Preliminary Site Investigation conducted in ' September 2008.

Project#200370 Site Investigation Report November 2008 2.0 INVESTIGATION PURPOSE AND SCOPE ' The objective of the Preliminary Site Investigation was to: • define the vertical and horizontal extent of possible hydrocarbon impacted soils within the proximity of the known pipe leak; ' • obtain certified analytical data on hydrocarbon.concentrations in soil samples; • if groundwater was encountered, collect grab samples for analysis of potential impacts from the fuel leak; • evaluate the-Site Investigation results to determine if further investigation or remediation is necessary; and • present the findings of the Site Investigation.and recommendations to the BFD. ' To meet these objectives the Site Investigation.included the following tasks: J g • sample soils at five-foot intervals from three borings drilled with a hollow-stem auger to evaluate the extent of hydrocarbon containing soils at the Site; • record soil characteristics and field PID measurements in field boring logs; and • . analyze selected soil samples for TPH-g, BTEX; and fuel oxygenates. This Report presents and evaluates the findings of the Preliminary Site Investigation ' conducted on September 24, 2008. 3.0 SITE DESCRIPTION ' 3.1 Site Description Currently,the Jaco Owned Fastrip mini-market and self-serve gas station operate ' on the Site. The gas station distributes gasoline and diesel from 2 dispenser islands with 2 dispensers per island and 3 underground storage tanks(USTs), consisting of one 12,000-gallon regular unleaded gasoline, one 12,000-gallon premium gasoline,.and one 12,000-gallon diesel UST. The service station is located on the northeast corner of the intersection of Mt. Vernon Avenue and University Avenue in Bakersfield, California. Adjacent to the service station to ' the south is a residential area, and to.the north east and west are parking areas associated with the adjacent Bakersfield College. ' 4.0 TOPOGRAPHY,GEOLOGY AND HYDROGEOLOGY 4.1 Topography The Site is at an elevation of approximately 700-feet above sea level. The topography slopes moderately to the southwest(see Figure 1 —Area Map). R:\2000_081370_PIER_3501 Mt.Vemon Ave.doc 6 3501 Mt.Vernon Avenue,Bakersfield RAM Environmental Engineering,Inc. Project#200370 Site Investigation Report November 2008 4.2 Geology The Site is located in the San Joaquin Valley, which is the southern portion of the Great Valley geomorphic province. The Great Valley is a large alluvial plain approximately 50-miles wide and 400-miles long; it is a trough in which sediments have been deposited almost continuously since the Jurassic (about 160 million years ago). Granitic and metamorphic rocks outcrop along most of the eastern and southeastern flanks of the Great Valley, while marine rocks of pre- Tertiary age outcrop along most of the western flank. The post-Eocene-aged continental rocks and deposits in the valley trough contain most of the fresh ' ground water, and are underlain by or contain saline water at depth in most places. They,range in thickness from zero along the flanks,of the Great Valley to more than 15,000 feet in the extreme southern part,where the base of the fresh water ' lies at a maximum depth of about 4,700 feet. The uppermost sedimentary units in the vicinity of,the Site are Quaternary, ' Recent.fan deposits. Subsurface soils at the site are sands containing gravels and cobbles. ' 4.3 Hydrogeology. Groundwater within the southern San Joaquin Valley is derived from rivers . flowing from the`.Sierra Nevada Mountains to the east. The closest-river to the ' Site is the Kern River located approximately 4,700 feet to the northwest. ' There are no surface waters in the immediate Site area. The regional unconfined groundwater at the Site is at approximately 480 feet below ground service(bgs); the groundwater flows to the north(KCWA 2004). ' 4.4 Past leak,.1994 A survey of Leaking Underground Fuel Tank(LUFT) sites in the area on the California State Water Resources web site"GeoTracker" shows that a leak was ' discovered at the Site in 1994. According to Mr. Craig Perkins of the BFD,the leak was a"non-petroleum spill". The case was closed in 1995. ' 4.5 Public drinking water wells The Kern County Water Agency map of Water Wells and Spreading Areas (April ' 2004, Plate 3) shows no water wells in the Site vicinity: 5.0 QUANTITY OF CONTAMINANT RELEASED The'quantity'of contaminant released is unknown. ' R:\2000_08\370_PIER_3501 Mt.Vernon Ave.doc 7 3501 Mt. Vernon Avenue,Bakersfield RAM Environmental Engineering,Inc. Project#200370 Site Investigation Report November 2008 ^ 6.0 SITE INVESTIGATION Three borings were developed at the Site with a hollow-stem auger drilling rig on September 24, 2008. All three borings(Borings B-1,B-2 and B-3)were drilled to 20 feet ' below ground surface (bgs): Soil samples were collected at five-foot intervals and selected soil samples were analyzed as follows: ' • Total petroleum hydrocarbons as.gasoline (TPH-g, carbon range C6-C10)by EPA Method 8015M, ' • Total petroleum hydrocarbons as diesel (TPH-d, carbon range C 1 o-C28) by EPA Method 8015M, ' i Benzene, Toluene, Ethyl-benzene and Xylene (BTEX) by EPA Method 8260B, and • Oxygenates,t-Butanol (TBA) Tert-Butyl Alcohol, Methyl Tert-Butyl Ether (MTBE), Diisopropyl Ether(DIPE), Ethyl Tert=Butyl Ether(ETBE), Tert-Amyl Methyl Ether(TAME), by EPA Method 8260B. 6.1 Boring Closure ' When the total depth'of the boring was reached, as determined in the field from observations,the boring was backfilled with cement grout. The surface was be compacted and covered with asphalt to match existing grade. ' 6.2 Waste.Management Drill cuttings'(soil)generated by drilling soil borings were placed in labeled drums and left on-site. The drum contents were transported by Coles Services under non-hazardous waste manifest to the Coles Services facility located at 1620E. Brundage Lane on October 20, 2008. Please see Attachment D for ' copies of the non-hazardous waste manifests. 7.0 RESULTS Lithologic logs were constructed from each boring, and are included in Attachment-B. Field observations did not indicate the presence of hydrocarbons in any of the borings or soil samples collected. ' To confirm the field observations, analyses were,requested_on the lowermost two soil samples from each boring only. The two deepest soil samples from Boring B-3 contained MTBE at concentrations equal to.or just above the laboratory reporting limit. Analyses were then requested for the shallow soil samples from Boring B-3, the analytical results indicated that there were no chemicals of concern present above the laboratory detection ' limit. A summary of analytical results is shown in Table 1 following the text; complete laboratory reports are included in Attachment C. R:\2000_08\370_PIER_3501 Mt.Vernon Ave.doc 8 ' 3501 Mt.Vernon Avenue,Bakersfield RAM Environmental Engineering,Inc. Project#200370 Site Investigation Report ' November 2008 8.0 DISCUSSION and RECOMMENDATIONS ' Low concentrations of MTBE, 5.7 and 5.0 ug/Kg, were found in two soil samples collected in Boring B-3. The industrial soil screening level guideline established by the US EPA (September.2008) for MTBE is 1,900,000 ug/Kg; the concentration of MTBE found at the Site is well below the soil screening guidelines. No odor or visible staining was noted in any of the borings developed at the Site. ' Based on the following points, RAM recommends that no further action be required at this Site: • The vertical separation between the low concentration of MTBE found in the soil and the underlying groundwater is approximately 450 feet, • the concentrations of MTBE found are well below the soil screening levels established by the.US EPA, • the impacted soils are not located close to a building, and • the impacted soils are,covered by asphalt. t 1 1 .

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. U Undetected at the laboratory method detection limit. X % Recovery and/or RPD out-of-range. Z Analyte presence was not confirmed by second column or GC/MS analysis. 7440 Lincoln Way, Garden Grove, CA 92841-1427 TEL:(714) 895-5494 FAX: (714) 894-7501 1 ' Page P elofI g 12 0 5 Don Burley From: Jane McNaboe Umcnaboe @ram-env.com] Sent: Friday, October 03, 2008 11:51 AM To: Don Burley Cc: Rena Hamblin ' Subject: Jaco Mt.
