Street, Bakersfield, CA 93306 Dear Mr. Roehi: I'm in receipt of the above-referenced document which indicates petroleum hydrocarbons are present in the soil at concentrations above state action levels. However, this site has had previous leak investigations. Unfortunately, the current baseline site a.ss~ssment did not go as far as to correlate thc hydrocarbons detected with any of the previous site characterizations. Therefore, please re-submit the findings of the baseline r~port, together with a professional geologic analysis of how thc findings relate to the site characteristics and regulatory history. Also, be advised that regulatory oversight for review of the data, and subsequent geologic analysis will. be billed to you at a rate of $87 per hour. Sincerely, Ralph E.

Samples taken from soil borings B-4 and B-5, drilled in the vicinity of the previous waste oil tank, were analyzed to detect the presence and concentration of total petroleum hydrocarbons as referenced to gasoline and diesel (modified EPA Method 8015), volatile aromatics (EPA Method 8240), and oil and grease (EPA Method 503). Additionally, a total of five soil samples were randomly selected to be analyzed to detect the presence and concentration of total lead (DOH$ LUFT Method).

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 critical zone, which Is defined as'10 feet from any part of the UST system as well as the area between the dispensers and USTs, 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. A site-specific, worker health and safety plan, including a JSA and traffic control plan for all soil sampling locations for the site, Is available at all times during drilling activities. Prior to commencing field activities, a health and safety'meeting is held among all on-site personnel Involved in the operations, including subcontractors and visitors, and is documented with a health and safety meeting sign-in form. 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 drifting activities. In order to determine the natural subsurface conditions, better recognize fill conditions, and prevent cross contamination, the first sampling location is generally located the furthest from any suspected underground improvement. When drilling a soil boring in asphalt or concrete, a minimum 10-inch round cut is made. When advancing a direct-push location, a minimum 3.5-inch round cut is made. REVISED 01/17/0~ I I I I I I I I I I I I I I I I I I HFA's Standard Operating Procedures for Soil Boring, Direct-Push Sampling, and Well Construction Page 2 Itole Clearance The minimum hole clearance depths are 5 feet below grade (fbg) oUtside the critical zone and 8 fbg within the critical zone and are conducted as follows: 0 to 5 fbg: The area to be cleared exceeds the diameter of the largest tool to be advanced and is large enough to allow for visual inspection of any obstructions encountered. The first 1 to 2 feet of soil or'fill is removed by hand digging, then the borehole is probed using a blunt-tipped tool to ensure that 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 3 feet. 5 to 8 fbg: For the soil borings located Inside the critical zone, probing and handclearing an additional 3 feet Is performed. If probing is met with refusal, then trained personnel advance a hand auger without excessive force. 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, ff subsurface conditions prevent adequate subsurface clearance, the field activities cease until the.client gives written approval of a procedure for continuation. When pea gravel, fill sand, or other non-indigenous material 'is encountered, the sampling location is 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 holes are covered with plates and/or backfilled. 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 as required by the client. The hole is backfi!led only with client approval. HFA's Standard Operating Procedures for Soil Boring, Direct-Push Sampling, and Well Construction Page 3 SOIL SAMPLING PROCEDURES Soil samples are collected using one of the following methods: · Manual drilling:' Manual drilling utilizes a hand auger. Soil samples are collected with a drive sampler outfitted with steel or brass sleeves. The specific equipment used is noted on a Icg of exploratory boring. Truck-mounted, powered drilling: Truc'k-mounted, powered drilling utilizes hOllow-stem flight auger drilling, air rotary drilling, 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 Icg of exploratory boring. Direct push sampling: Direct push sampling utilizes Geoprobes, cone penetrometer testing rigs, or similar technologies. Soil samples are collected with a drive sampler outfitted with steel, acetate_or brass sleeves. The specific equipment used is noted on a Icg of soil sample descriptions. Before each soil sampling episode, the sampling equipment is decontaminated using a non-phosphate soap and water wash, and two tap-water rinses. The drill augers or direct-push rods are decontaminated with a steam cleaner between each soil boring (truck-mounted rigs). Soil samples that are collected in sample sleeves are covered with aluminum foil or Teflon tape followed by plastic caps. ff EPA Method 5035 is required, then 5 to ~13 grams of soil Is extracted from the sample and placed in methanol-preserved containers supplied by the laboratory, or subsamples are collected using Encore® samplers. During the sampling process, soil samples and cuttings are field screened for VOCs using a photoionization detector calibrated to an isobutylene or hexane standard. The calibration information is recorded on an equipment calibration Icg. 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 are recorded on a soil boring Icg 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 or the Arizona Department of Environmental Quality's (ADEQ's) Leaking Underground Storage Tank Site Characterization Manual. Sample preseryation, handling, and transportation procedures are consistent with Holguin, Fahan & Associates, Inc.'s quality assurance/quality control procedures. The samples are transported in a chilled container to a state-certified, hazardous waste testing laboratory. il I I I I I I I I I I I I I I I HFA's Standard Operating Procedures for Soil Boring, Direct-Push Sampling, and Well Construction Page 4 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 as waste material or non-hazardous waste, with the number of the soil boring(s) from which the waste was derived, the date the waste was generated, the generator 'name, and other pertinent information. The drums are stored at the site of generation, or at another location approved by the client until sample laboratory analytical results are obtained, at which time the soil is disposed of appropriately. A soil boring Icg is completed for each soil sampling location and includes the following minimum information: · date of drilling; · project name and location; · soil sample names and depths; · soil.descriptions and classifications; · standard penetration counts (rigs); · photoionizatlon detector readings; · drilling equipment; · soil boring diameter; · sampling equipment; · depth to groundwater in soil boring; · name of person performing logging; · name of supervisin'g registered geologist; and · name of drilling company (rigs and direct push). HYDROPUNCH GROUNDWATER SAMPLING PROCEDURES Hydropunch sampling of groundwater Is designed for collecting discrete, one-time samples of groundwater for analysis during the drilling or direct-push operations. The Hydropunch sampler consists of a 5-foot long, 1.5-inch diameter screen sheathed by a 2-inch diameter, steel barrel. A disposable point is connected to the bottom of the screen. · The Hydropunch assembly is lowered through the hollow-stem auger and driven into the undisturbed soils below the base of the hole, or is pushed into the soil using a direct push rig. The outer sheath is then retracted t© expose the screen. A bailer is then lowered into the Hydropunch assembly and retrieves a sample of the groundwater within the assembly. The extracted groundwater is collected in chilled, 40-milliliter, volatile organic analysis vials having Teflon-lined caps, or other appropriate containers as required by the respective analytical method. FOr organic compound analyses, hydrochloric acid preservative is added to all containers by the laboratory to lawer sample pH. Samples are held at 4°C while in the field ?1 I I I I I I I I I I I I I I I I and in transit to the laboratory. testing laboratorY. HFA's Standard Operating prOcedures for Soil Boring, Direct-Push Sampling, and Well Construction Page 5 Analysis is performed by a state-certified, hazardous waste Documentation requirements Include: · sample identification number; · boreho~le identification number; · time and date of sample collection; · depth at which HydropUnch sample was collected; · name of person collecting sample; · 'number and types of sample containers; and · type of preservative used, if any. BOREHOLE COMPLETION PROCEDURES All samPling locations_are either properly abandoned or completed as a well. Abandonment Each borehole/sample location 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 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 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; and · surtace seal design/construction. Groundwater monitoring wells are generally designed with 30 feet of slotted casing that crosses the water table, unless site conditions, project needs, or local regulations dictate a different well design. Vadose wells are designed with slotted casing appropriate for the project needs, e.g. I ! I I I I I I I I I I I I il HFA's Standard Operating Procedures for Soil Boring, Direct-Push Sampling, and Well Construction Page 6 slotted in hydrocarbon-containing intervals for vapor extraction. Air sparging wells are typically designed with 5 feet of slotted casing placed 15 feet below the water table. The sand pack is placed at least two feet above the top of the screen, and at least 3 feet of Iow permeability seal material is placed between the sand pack and the surface seal, unless shallow groundwater conditions exist (less than 5 fbg). The sand pack and Iow permeability seal material are placed in the annular space from the bottom up.using the tremle 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 or 24-inch circle is sawcut. The well cover is traffic-rated and has a white lid with a black triangle painted on it (3 inches per side) ora black lid with a white triangle (3 inches per side). The well pad is completed using concrete of a color matching the existing surface. The well number is labeled on the outside of the well box/pad 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 casings are capped with a locking or slip well cap. Well Development Well development is conducted by the use of surge blocks, bailers, pumps, or other appropriate methods in accordance with the requirements of the California Department of Water Resources Bulletin #74-81 dated December 1981, or ASTM International 4448-85a (as required by the ADEQ). Only formation water is used for surging the well. Well development continues until non-turbid groundwater is produced or turbidity stabilizes. The method of development and the volume of groundwater produced is recorded in the field Icg. All purged groundwater is held on-site, or at another location approved by the client, in sealed, 55-gallon DOT approved drums or other appropriate containers pending transport to an approved recycling facility. Well Elevation Survey 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 may be 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. I I I I I I I I I I I I I I I I HFA's Standard Operating Procedures for Soil Boring, Direct-Push .Sampling, and Well Construction Page 7 DATA REDUCTION The data compiled from the soil borings are summarized and analyzed. A narrative summary of the soil characteristics is also presented, The logs are checked for the following information: * correlation of stratigraphic units among sampling locations; · 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.

Site-specific information is provided on the cover page of this document. Prior to the start of each day's field activities, the HASP will be reviewed by all on-site personnel at a health and safety tailgate meeting, All on-site employees, subcontractors, and regulatory agents will acknowledge that they have reviewed the HASP by signing the tailgate meeting form (see Appendix 1 for the form). This HASP was developed by HFA's industrial hygienist through consultation of the following documents: Occupational Safety and Health Administration (OSHA) 29 CFR 19.10- "Hazardous Waste Operations and Emergency Response, Final Ruling," March 1989; · National Institute of Occupational Safety and Health/OSHA/United States Coast Guard/Environmental Protections Agency "Occupational Safety and Health Guidance Manual for Hazardous Waste Site Activities," October 1985; · HFA's Corporate Health and Safety Program; · ExxonMobil Oil Corporation's Operations Integrity Management System; and · Chevron Environmental Management Company's Loss Prevention System, 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 any UST site Include an evaluation of any present or potential threat to worker and public safety. Questions need to be answered regarding the dangers of significant vapor exposures and potential explosion hazards. REVISED 10/1/03 I I I I I I I I I I I I I I I I I I Worker Health and Safety Plan Page 2 An analysis of known and potential site-specific hazards is outlined in the Job Safety Analysis in Appendix 2. Potential Chemica! Hazards The chemical components of gasoline that are the most dangerous to site workers are gasoline, hydrocarbon-containing soil, benzene, toluene,, ethylbenzene, xylene, methyl tertiary butyl ether (MTBE), and potentially, organic lead (see Appendix 3 for the Material Safety Data Sheets), In addition, solvents such as 1,2-dichlorobenzene and 1,2-dichloroethane may be used as cleaning solutions at service stations. The primary health risks associated with each chemical are described below. Gasoline (free-phase) - Confirmed animal carcinogen with unknown relevance to humans. A_threshold limit value (TLV) (8-hour average) of ~ parts per million by volume (ppmv) and a short-terra-exposure limit (STI:L) (15 minute average) of 500 ppmv have been assigned to gasoline (see Appendix 3). This value of was assigned based on an average of 2 percent benzene (0.5 ppmv TLV) in.gasoline. Low-level inhalation exposure to gasoline can cause irritation to the eyes, nose, and respiratory system; headache; dizziness; and nausea. Contact with the skin causes irritation. Hydrocarbon-containing soil- Generally contains less than 1 percent gasoline. A TLV of 300 ppmv has been assigned to soil containing gasoline hydrocarbans. Benzene - Known human carcinogen. A TLV of 0.5 ppmv or 1.6 milligrams per cubic meter (mg/m3] and an STEL of 2.5 parts per million (ppm] have been assigned to benzene. Benzene has a Iow odor threshald limit of 1.4 ppm. LowLlevel inhalation expasure ta benzene can cause irritation to the eyes, nose, and respiratory system; dizziness; headache; and nausea. To uene - A TLV of 1,500 ppm or 187.5 mg/m3 has been assigned to toluene. Toluene has a Iow odor threshold limit of 2.1 ppm. Low-level inhalation exposure to toluene can cause fatigue, weakness, confusion, and euphoria. Ethylbenzene- A TLV of 100 ppm or 435 mg/m3 has been assigned to ethylbenzene. Ethylbenzene has a Iow odor threshold limit of 2 ppm. Low-level inhalation exposure to ethylbenzene can cause irritation to the eyes and mucous membranes. X¥1ene- A TLV of 100 ppm or 435 mg/m3 has been assigned to xylene. No Iow odor threshold limit has been established for xylene. Low-level inhalation exposure to xylene can cause dizziness, headache, nausea, and drawsiness. I I I I I. I I I I I'1 I I IlI Worker Health and Safety Plan Page 3 MTBE- Confirmed animal carcinogen with unknown relevance to humans, A TLV of 40 ppm or 144 mg/m3has been assigned to MTBE. In laboratory animals, inhalation exposure can cause hyperactivity, coordination problems, convulsions, and Unconsciousness. Ethanol- A TLV of 1,000 ppm or 1,900 mg/m3 has been assigned to ethanol.. High-level inhalation exposure can cause eye and respiratory tract irritation, fatigue, headache, and "drowsiness. No reports of chronic exposure to vapors have been reported. Tetraethyl Lead (Organic 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 are available concerning odor threshold. Acute vapor exposure can cause insomnia, delirium, coma, and skin irritation. 1,2-Dichlorobenzene- A TLV of 50 ppm or 306 mg/m3 has been assigned to 1,2-dichlorobenzene. 1,2-dichlorobenzene has a Iow odor threshold limit of 4.0 ppm. Acute vapor exposure can cause coughing, drowsiness, and skin irritation. 1,2-Dichloroethane - A TLV of 200 ppm has been assigned to 1,2-dichlorethane, No data are available concerning odor threshold. Acute vapor exposure can cause coughing, dizziness, drowsiness, and skin irritation. Potential Physical Hazards Trenching - Fuel vapor levels will be monitored using a lower explosive limit (LEL)meter or photOionization detector (PID]. The presence of underground utilities and fuel facilities is alsa of concern, and the applicable utility markout service will be notified in advance of any trenching work for identification of all underground structures in the immediate area. Drilling - Fuel vapor levels will be monitored using a PID or LEL meter. The presence of underground utilities is also oI~ concern, and the applicable utility markout service will be notified in advance of any drilling work for identification of all underground utilities in the immediate area. Excavations- Fuel vapor levels will be monitored using a PID or LEL meter. All excavations greater than 4 feet in depth will not be entered unless the excavation is properly sloped or shared in accordanCe with OSHA regulations and certified by a competent person. Confined spaces are never to be entered. I I I I I. I I I I I I I I I I I Worker Health and Safety Plan Page 4 Sampling- Use of personal protective equipment and decontamination procedures will minimize the potential for exposure for personnel conducting site investigation aCtivities. ' ]traffic -In areas where vehicular traffic is anticipated, a traffic control plan will be developed as part of the HASP. A traffic vest will be worn, traffic control devices will be placed around the work area, and wOrkers will face oncoming traffic, as conditions allow. The vehicle should be placed between the work area and oncoming traffic, where possible. For 'work in the public right-of-way, traffic control (delineators, signs, light boards, and so forth) will be setup in accordance with the Work Area Traffic Control Handbook and local agency requirements as outlined in the Permit. For high-risk traffic areas, at least two workers will be present. Heat - The effects of high temperatures will be monitored by each individual and by all coworkers at the site. If site ambient temperature exceeds 90°F and the potential for heat stress is considered to be high as .indicated on the site-specific information page, the effects should be controlled through regular work breaks; wearing loose, lightweight clothing; working during cooler hours of the day; and ingestion of cool fluids (recommended 8 ounces every 20 minutes) as outlined in the American Conference of Governmental Industrial Hygienists' Guidance for heat stress conditions. Common heat disorders, symptoms, and first aid measures include the following. Heat cramps - Heat ·cramps are caused by dehydration and loss of salt, Its'symptoms include spasms or cramps in the limbs and hot skin, Workers should consume fluids at frequent intervals, Heat exhaustion - Symptoms include thirst, headache, clammy skin, nausea, vertigo, weakness, and fainting. Clothing should be loosened, and the worker should be removed from the hot environment and given fluids and adequate rest. Heatstroke - Symptoms include red, dry skin; confusion; irrational behavior; lack of sweating; convulsions; and potentially loss of consciousness. ProfesSional medical .assistance should be called immediately. In the interim, the worker should be taken out' of the hot environment, outer clothing should be removed, the skin should be welled, and the worker should be given fluids. 2. EXPOSURE MONITORING PLAN Potential exposure hazards found at UST sites primarily include liquid gasoline or airborne vapors from leaking USTs or associated piping, containment boxes, sumps, and hydrocarbon-containing soil and groundwater, I .I I I I I I I I I I I I I I I I Worker Health and Safety Plan Page 5 The most dangerous airborne vapor likely to be encountered during a UST investigation is benzene. Gasoline vapor concentration levels will be monitored in the breathing zone with a PID, calibrated prior to use on a daily basis to an isobutylene standard, or an LEL meter using a hexane standard. The calibration will be recorded, and a copy of the documentation will be kept with the PID and LEL. When the action level of 150 ppmv (one-halt of the TLr of gasoline) is detected and sustained in the breathing zone, respiratory protection will be required using full-face or half-face respirators with organic vapor cartridges (Level C protection), and vapor suppression, ventilation, or other engineering controls may be applied. Monitoring for combustible gases will also be performed using an LEL meter when vapor cOncentrations in excess of 2,000 ppmv are detected with the PID. The withdrawal level is 20 percent of the LEL for gasoline vapors, or 2,800 ppmv, in the breathing zone. If this level is exceeded, the work party will be IMMEDIATELY withdrawn from the work area 3. PERSONAL PROTECTIVE EQUIPMENT The level of protection during the site investigation will usually be Level D. Level D protective equipment includes: long pants, safety boOts, traffic vest, hearing protection, safety glasses, gloves, and hard hats if drilling or trenching operations are in progress. A flame-retardant suit is required if phase-separated hydrocarbons are encountered. Upgrading the protection level would be based on airborne vapor concentration equaling or exceeding the action level (150 ppmv]. An upgrade to Level C protection would be required if the action level Is equaled or exceeded. The equipment required for Level C would be a full- face or half-face, air purifying respirator and may include Tyvek suits with taped arm and leg seals, in addition to the Level D protective equipment. If the vapor concentrations exceed 1,000 ppmv, canister-equipped respirators will be used. If the withdrawal level is .met or exceeded (20 percent of the LEL in the breathing zone), work will cease until the vapor level is measured to be below 20 percent of the LEI, and vapor suppression, ventilation, or Other engineering controls will be applied. It the OSHA Permissible Exposure Limit or a time-weighted average of 85 decibels is exceeded, or if heavy equipment (i.e., jackhammer, drill rig, backhoe) is used, hearing protection will be worn. A fire extinguisher, first aid kit, and eyewash will be maintained on-site. Decisions for workers' safety and the personal protective equipment to be worn are based on a continual evaluation of conditions. I I I I 'il I I I i I I I I I I Worker Health and Safety Plan Page 6 4. WORK ZONES AND SECURITY MEASURES To facilitate a minimum exposure to dangerous vapors and/or physical .hazards, only authorized persons will be allowed in the work zone.· Work zones will be defined by the client, · the general contractor, or HFA staff, who will also be responsible for maintaining security within these zones. The work zone will be delineated from the jOb site using traffic delineators, caution tape, and so forth. A traffic control plan delineating the work zone will be developed as part of the HASP. Only the minimum number of personnel necessary for the UST investigation will be present in the work zone. Smoking is never permitted in the work zone. 5. DECONTAMINATION AND DISPOSAL HFA's standard operating procedures (SOP) establish practices that minimize' contact with potentially impacted materials. Decontamination procedures are used if there is 'suspected or known impacted equipment, supplies, instruments, or any personnel surfaces. Nitrile gloves · should .be worn during, decontamination activities.. The equipment will be decontaminated using a nonphosphate soap and water wash and two tap-water rinses. Wash water will be recycled in accordance with the appropriate regulatory procedures and HFA's SOP for soil boring, direct-push sampling, and well construction. 6. EMPLOYEE TRAINING All applicable HFA employees working on the site will have had, at a minimum, the required 40-hour OSHA Training for Hazardous Waste Site Activities With annual 8-hour refresher training and medical surveillance exam (29 CFR 1910, 120), which includes training in the use of respirators and other personal protective equipment. Annual individualized respirator fit testing is required of all applicable HFA employees working at the site. Personnel in a supervisory role will have undergone an 'additional 8 hours of training in accordance with OSHA requirements (29 CFR 1910, 120, page 373 [4]]. 7. EMERGENCY PROCEDURES If an emergency occurs, on-site personnel will contact EMT personnel by dialing 911. All work will cease, and reasonable efforts will be made to secure the work area, if it is deemed safe to do so. 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 attached]. In the event of a~more serious injury, site personnel will contact the local emergency services by dialing 911 for assistance. I I I I I I I I I I I I Worker Health and Sa!ety Plan Page 7 If a fuel release occurs as a result Of site investigation activities, the emergency shutoff switch at active service station locations will be activated. Absorbent or other available material (i.e,, bentonite and cat litter) will be placed around the spill to prevent' the substance from entering utility vaults or the public right-of-way. A work zone will be setup around the release, and fuel vapor levels will be monitored with an LEL or PIP. 'The appropriate agencies will be. notified in accordance with local regulations, and all absorbent material will be disposed of~ in an approPriate manner. In the event of a major emergency or natural disaster, all workers will evacuate the work area and meet at a previously designated safe area, where all personnel will be accounted for.

The mechanism of this response is still being investigated but it is thought to be an ap(genetic process unique to the female mouse. Inhalation exposure to whole gasoline vapor also caused kidney damaqe 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. The data above is obtained from studies sponsored by the American Petroleum Institute (APl). This product contains benzene. The OSl~ Benzene Standard (29 CFR 1910.1028) contains detailed requirements for training, exposure monitoring, respiratory protection and medical surveillance triggered by the exposure level. Refer to the OSHA Standard before using this product. Repeated or prolonged breathing of benzene vapors has been associated with the development of chromosomal damage in experimental animals and various Revision Nunber: 14 Revision Date: 05/12/93 NSDS Number: 002655 NDA - No Data Available NA - Not Applicable I I I I R£GULARUNLEADED GASOLINES Page 8 o~ 4! blood diseases in humans ranging from aplastic anemia to leukemia (a form of cancer). All o~ these diseases can be fatal No birth.defects have been shown to occur in pregnant laboratory animals exposed to doses not toxic to the mother. However, some-evidence of fetal toxicity such as delayed physical development has been seen at such levels. The available information on the effects of benzene on human pregnancies is inadequate but it has been established that benzene can Cross the human placenta. This product contains n-hexane. Prol°nged or repeated skin contact or breathing of vapors may cause nerve damage characterized by progressive weakness and numbness in the arms and legs. Recovery ranges from no recovery to complete recovery depending upon the severity of the nerve damage. This product contains toluene. Toluene has been reported to decrease inu~unological responses in test animals. It has also been reported that when young rats were exposed to 1000 ppm toluene for 14 hours daily, for two weeks, irreversible hearing loss was detected. The same daily exposure to 700 pp~ for as long aa 16 weeks was without effect. Since the level necessary to produce hearing loss is greater than 7times the AC~IH TLV-~IA for toluene, worker exposures at or below 100 ppm is not expected to cause any adverse effects. There are also reports tl~at chronic solvent abusers (glue sniffers, solvent buffers) who deliberately inhale high concentrations (several thousand ppm) of toluene for prolonged periods (up to ten hours/day) have suffered liver, kidney and brain damage. Toluene may also cause mental and/or growth retardation in the.children of female solvent abusers who directly inhale toluene when they are pregnant. Toluene caused growth retardation in rats when administered at doses that were toxic to the m°thers (1500 ppm). Concentrations of up to $000 ppm did not cause birth defects. There were no effects in the offspring at doses that did not intoxicate the pregnant rats. The exposure level at vhich no effects vere seen (No Observed Effect Level, NOEL) is 750 1~1~. ~e recommend that the precautions outlined in this HSDS be folloved to keep toluene concentrations belov the recommended exposure standards' This product contains xylene, a chemical that has been reported to cause developmental toxicity in rats and mice exposed by inhalation during pregnancy. The effects noted consisted of delayed development and minor skeletal variations~ additionally, when pregnant mice were exposed by ingestion to a level that killed nearly one-third of the test group, lethality (resorptions) and malformations (primarily cleft palate) occurred. Malformations have not been reported following inhalation exposure. Because of the very high levels of exposure used in these studies, we do not believe that their results imply an increased risk of reproductive toxicity to workers exposed to xylene levels at or below the exposure standard. Xylene has.given negative results in several mutagen testing assays including the Ames assay. In a cancer study sponsored by the Eational Toxicology Program (NTP), technical grade xylene gave no evidence of' carcinogenicity in rats or mice dosed daily for two years. Mixed xylenes have been shown to cause probable hearing loss in rats 'exposed to 800 ppm in the air for 14 hours per day for six weeks. Revision Number:~14 Revision Date: 05/12/93 HSDS Number: 002655 NDA - No Data Available NA - Not Applicable I I I I I I I I I GASOLINES Although no information is available for lower concentrations, other chemicals that cause hearing loss in rats at relatively high concentrations do not cause hearing loss at low concentrations- Hen exposed to 335. to 400 ppm of m-xylene for over 3 hours per day for a total of 4 days shoved no hearing loss. Worker exposure to xylenes at the permissible exposure limit (100'ppm, time-veiqhted, average) is not expected to cause hearing loss. This procluct can contain methyl tert butyl ether (I~TBE). Nost mutagenicity data on HTBE, including the Ames Test, indicate that it is not mutagenic. Hoverer, one test called 'mouse 1ymphoma' vas positive under certain conditions.' The positive results are thought to be due to a metabolite (formaldehyde) and not HTBE directly. MTBE vas shown to cause maternal toxicity at exposure levels of 4,000 and 8,000 ppm vhen mice vere exposed for 6 hours per day during their pregnancy. A decrease in the nund~er of successful pregnancies and a reduction in birth veiGht vas also seen at those exPosure levels. A significant number of Pups had a birth defect (cleft palate) at the 8,000 ppm exposure level. The exposure concentration vhere there vu no maternal toxicity or' birth defects vas determined to be 1,000 ppm... There vere no birth defects in rabbits exposed to the same 14~ concentrations. (up to 8,000 ppm). No birth defects vere observed in rats exposed to HTBE ~t concentrations up to 2,500 ppm. These results suggest that the risk of birth defects in humans from NTB~ is negligible at the anticipated exposure concentrations. MTBE exposure for 18 months caused an increased incidence of liver tumors in female mice. The increase vas only observed in the high dose group (8000 ppm). I~TBE exposure for 24 months caused an increased incidence of kidney and testicular tumors in male rats. Whole gasoline-exhaust vas revieved by the International Agency for ResearCh on Cancer (IARC) in their Monograph Volume 46 (1989). Evidence for causing cancer vas considered inadequate in aniraals andinadequate in humans. IARC placed vhole Gasoline exhaust in Category 2B, considering, it possibly carcinogenic to humans. 12.

The original site configuration consisted of two lO,O00-gallon gasoline USTs, one 5,000-gallon gasoline UST, -one 1,000-gallon used-Oil UST,- qndtwo dispenser islands along the east-central portion of :the site. A third dispenser island Was added sometime _before 1988 (see Figure 2 for former site facilities). The former site fac t es were rePlaced in July 1988. The new facilities include three lO,O00-gallori fiberglass gasoline USTs, four dispensers on two dispenser islands, and ;the associated piping. The product Piping and dispensers at the site were upgraded in 1995 (SECOR, 2003!. PREVIOUS WORK In July 1-988, the former used-oil UST, product piping, and dispensers at the site were remove~l .

HFA concluded that based on the available laboratory analytical data, it-was difficult to de~ermine if the hydrocarbons encountered in the vicinity of the' former western dispenser island are related, to the hydrocarbons encountered in soil :boring BA-3, The chemic-al composition of each release was indicative.of an older. Source.t. hat is depleted of' benzene. However, based on the limited extent of adsorbed-phase hydrocarbons encountered in the vicinity of the former western dispenser island and the proximity of adsorbed-phase hydrocarbons in boring BA-3 to the existing USTs, it appeared that the sources of the hydrocarbons might be unrelated.

A geophysical survey was conducted at the site on March 16, 2004, to aid in identifying piping, conduit, utilities, and other buried features beneath the site. Underground.Services Alert of Southern California and the CBFD were notified at least 48 hours prior to conducting the work. I I I I I I SOIL BORINGS ; On April 19 and 20, 2004, three soil borings (B-8 through B-lO) were drilled using a hollow-stem .auger rig (see Figure.2 for boring locations). Soil boring B-Swas' drilled to 60 tbg. Due to lack of sample retrieval at 40 fbg, soil borings B-9 .and B-10 were drilled to 65 fbg. This provided five successive soil samPles for vertical delineation. :.-An.attempt was made to collect soil samples at 5-foot intervals tothe total depth of each soil boring, usin=cj a California modifiedl split-spoon sampler; however, due. to the presence-of cobbles beneath the site, several samples could not be collected at 5-foot intervals. The soil samples were screened for hydrocarbons in the field with a PID and logged under the supervision of a State of California registered geologist (see Attachment 2 for procedures). The PID reading for each soil sample collected during this investigation was- 0 pPmv. Soils beneath the site consist predominantly of well graded sand with cobbles and gravel, with minor amounts of sand with silt and sandy Clay from grade to 65 fbg, the maximum dept. h of investigation (see Attachment 3 for the logs of exploratory borings). Groundwater was not encountered -during I I The soil Samples .were submitted to Del Mar Analytical, a California State-certified hazardous material-testing laboratory, and analyzed for TPH as gasoline using EPA Method 8015 (M) and for BTEX, MTBE, TBA, TAME, DIPEi and ETBE-using EPA Method 8260B.

I I I SUMMARY AND CONCLUSIONS ,Soils beneath the site consist predominantly of well graded sand with cobbles and gravel, with. minor amounts, of sand with silt and sandy clay from grade to 65 fbg, the maximum depth Of investigation. Groundwater was not encountered 'during drilling. Laboratory analytical results of soil samples collected from boring B-8 through B-lO indicated no detectable TPH as gasoline,. BTEX, MTBE, TBA, TAME, -DIPE, or ETBE. Ba§ed on the resui~s of current and previous investigations, the lateral and vertical extents Of-adsorbed-phase hydrocarbons'have-been delineated. The lateral extent of adsorbed-phase h~drocarbons above regulatory action levels is limited to the vicinity of the gasoline 'USTs (see Figure 3). The vertical extent of adsorbed-phase hydrocarbons above regulatory action levels is limited to. a depth of approximately 40 fbg (see Figure 4 - Geologic CroSs Section A-A'). Based on an estimated depth to groundwater of 200 fbg, there' is at least 150-feet of "clean soil" above groundwater. - I I RECOMMENDATIONS Based on the limited lateral and vertical extent of TPH as gasOline concentrations, the absence of benzene and.

HFA'S SOP FOR-SOIL BORING, DIRECT-PUSH SAMPLING, AND WELL CONSTRUCTION HOLGUIN, FAHAN & ASSOCIATES, INC.'S STANDARD OPERATING PROCEDURES FOR SOIL BORING, DIRECT-PUSH SAMPLING, AND WELL CONSTRUCTION PRE-DRILLING PROTOCOL Planning 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 2 weeks in advance of drilling, notifications are made to the property owner, client representative, on-site facility manager, regulatory agency, and/or other appropriate parties. At lea~t 48 hours prior to drilling, Underground Service Alert of Southern California, Arizona BJue Stake, or an equivalent utility locating service is notified. A geophysical survey may be conducted to locate subsurface utilities. Site plans and/or as-built drawings are compared t© actual conditions observed at the siie. 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 critical zone, which is defined as 10 feet from any part of the UST system as well as the area between the dispensers and USTs, 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. A site-specific, worker health and safety plan, including a JSA and traffic control plan for all soil sampling locations for the site~ is available at all times during drilling activities. Prior to commencing field activities, a health and safety meeting is held among all on-site personnel involved in the operations, including subcontractors and visitors, and is documented with a health and safety meeting sign-in form. 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. In order to determine the natural subsurface conditions, better recognize fill conditions, and prevent cross contamination, the first sampling location is generally located the furthest from any suspected underground improvement. when drilling a soil boring in asphalt or concrete, a minimum 10-inch round cut is made, When advancing a direct-push location, a minimum 3.5-inch round cut is made. REVISED 01/17/03 !! HFA's Standard Operating Procedures for Soil Boring, Direct-Push Sampling, and Well Construction Page 2 Hole Clearance The minimum hole clearance depths are 5 feet below grade (fbg) outside the critical zone and 8 fbg within the critical zone and are conducted as follows: 0 to 5 fbg: The area to be cleared exceeds the diameter of the largest tool to be advanced and is large enOugh to .allow for visual inspection of any obstructions encountered. The first 1 to 2 feet of soil or fill is removed by hand digging, then the borehole is probed using a blunt-tipped tool to ensure that 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 perfarmed ito 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 3 feet. 5 to 8 fbg: For the soil borings located inside the critical zone, probing and handclearing an additional 3 feet is performed. If probing is met with refusal, then trained personnel advance a hand auger without excessive force. 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 field activities cease until the client gives written approval of a procedure for continuation, When pea gravel, fill sand, or other non-indigenous material is encountered, the sampling location is abandoned unless the absence of subsurface facilities can be demonstrated and client approval to proceed is obtained, ff hole clearance activities are conducted prior to the actual day of drilling, the holes are covered with plates and/or backfilled. i! 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 as required by the client. The hole is backfilled only with client approval. !! i! HFA's Standard Operating Procedures for Soil Boring, Direct-Push Sampling, and Well Construction . Page 3 SOIL SAMPLING PROCEDURES Soil samples are collected using one of the following methods: · Manual drilling: Manual drilling utilizes a hand auger. Soil samples are collected with a drive sampler outfitted with steel or brass sleeves. The specific equipment Used Is noted on a Icg of exploratory boring. Truck-mounted, powered drilling: Truck-mounted, powered drilling utilizes hollow-stem flight auger drilling, air rotary drilling, 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 log of exploratory boring. Direct push sampling: Direct push sampling utilizes Geoprobes, cone penetrometer testing rigs, or similar technologies. Soil samples are collected with a drive sampler outfitted with steel, acetate or brass sleeves. The specific equipment used Is noted on a Icg of soil sample descriptions. Before each soil sampling episode, the sampling equipment is decontaminated using a non-phosphate soap and water wash, and two tap-water rinses. The drill augers or direct-push rods are decontaminated with a steam cleaner between each soil boring (truck-mounted rigs). Soil samples that are collected In sample sleeves are covered with aluminum foil or Teflon tape followed by plastic caps. ff 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 subsamples are collected using Encore® samplers. During the sampling process, soil samples and cuttings are field screened for VOCs using a photoionization detector calibrated to an isobutylene or hexane standard. The calibration information is recorded on an equipment calibration Icg. 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 are recorded on a soil boring Icg 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 or the Arizona Department of Environmental Quality's (ADEQ's) Leaking. Underground Storage Tank Site Characterization Manual. Sample preservation, handling, and transportation procedures are consistent with Holguin, Fahan & Associates, Inc.'s quality assurance/quality control procedures. The samples are transported in a chilled container to a state-certified, hazardous waste testing laboratory. HFA's Standard Operating Procedures for Soil Boring, Direct-Push Sampling, and Well Construction Page 4 Cuttings from the soil borings are stored in 55-gallon, Department of Tra~nsportation (DOT) approved drums, roll-off bins, or other appropriate containers, as approved by the client. Each container is labeled as waste material or non-hazardous waste, with the number of the soil boring(s) from which the waste was derived, the date the waste was generated, the generator name, and other pertinent information. The drums are stored at the site of generation, or at another location approved by the client 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 sampling location and includes the following minimum information: · date of drilling; · 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; · 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). HYDROPUNCH GROUNDWATER SAMPLING PROCEDURES Hydropunch sampling of groundwater is designed for collecting discrete, one-time samples of groundwater for analysis during the drilling or direct-push operations. The Hydropunch sampler consists of a 5-foot long, 1.5-inch diameter screen sheathed by a 2-inch diameter, steel barrel. A disposable point is connected to the bottom of the screen. The Hydropunch assembly is lowered through the hollow-stem auger and driven into the undisturbed soils below the base of the hole, or is pushed into the soil using a direct push rig. The outer sheath is then retracted to expose the screen. A bailer is then lowered into the Hydropunch assembly and retrieves a sample of the groundwater within the assembly. The extracted groundwater is collected in chilled, 40-milliliter, volatile organic analysis vials having Teflon-lined caps, or other appropriate containers as required by the respective analytical method. For organic compound analyses, hydrochloric acid preservative is added to all containers by the laboratory to lower sample pH. Samples are held at 4°C while in the field HFA's standard Operating Procedures for Soil Boring, Direct-Push Sampling, and Well Construction Page 5 and in transit to the laboratory. Analysis is performed by a state-certified, hazardous waste testing laboratory. Documentation requirements include:- · sample identification number; · borehole identification number; · time and date of sample collection; · depth at which Hydropunch sample was collected; · name of person collecting sample; · number and types of sample containers; and · type of preservative used, if any. BOREHOLE COMPLETION PROCEDURES All sampling locations are either properly abandoned or completed as a well. Abandonment Each borehole/sample location 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 melhod. Backfilling is performed carefully to avoid bridging. The type of backfill material is noted on the 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 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; and · surface seal design/construction. Groundwater monitoring wells are generally designed with 30 feet of slotted casing that 'crosses the water table, unless site conditions, project needs, or local regulations dictate a different well design. Vadose wells are designed with slotted casing appropriate for the project needs, e.g. i! .! HFA's Standard Operating Procedures for Soil Boring, Direct-Push Sampling, and Well Construction Page 6 slotted in hydrocarbon-containing intervals for vapor extraction. Air sparging wells are typiCally designed with 5 I~eet of slotted casing placed 15 feet below the water table. The sand pack is .placed at least two feet above the top of the screen, and at least 3 feet of Iow permeability seal material is placed between the sand pack and the surface seal, unless shallow groundwater conditions exist (less than 5 fbg]. The sand pack and Iow permeability seal material are placed in the annular space 'from the~ bottom up using the tremie method. Wl~en drilling in asphalt, a 24-inch round cut is made for the well pad. When drilling on concrete, a 2 x. 2-foot square or 24-inch circle 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 well pad is completed using concrete of a color matching the existing surface. The well number'is labeled on the outside of the well box/pad 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 casings are capped with a locking or slip well cap. Well Development Well development 'is conducted by the use of surge blocks, bailers, pumps, or other appropriate methods in accordance with the requirements of the California Department of Water Resources Bulletin #74-81 dated December 1981, or ASTM International 4'!,~.B-85a (as required by the ADEQ). Only formation water is used for surging the well. Well development continues until non-turbid groundwater is produced or turbidity stabilizes. The method of development and the volume of groundwater produced is recorded in the field log. All purged groundwater is held on-site, or at another location approved by the client, in sealed, 55-gallon DOT approved drums or other appropriate containers pending transport to an approved recycling facility. Well Elevation Survey 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 may be 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. HFA's Standard Operating Procedures for Soil Boring, Direct-Push Sampling, and Well Construction Page 7 DATA REDUCTION The data compiled from the soil borings are summarized and analyzed. A narrative summary of the soil characteristics is also presented. The logs are checked for the following information: · correlation of stratigraphic units among sampling locations; · 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. - ENVIRONMENTAL MANAGEMENT CONSULTANTS .....

However, this site has had previous leak investigations. Unfortunately, the current baseline site assessment did not go as far as to correlate the hydrocarbons detected with any of the previous site characterizations. Therefore, please re-submit the findings of the baseline report, together with a professional geologic analysis of how the findings relate to the site characteristics and regulatory history. Also, be advised that regulatory oversight for review of the data, and subsequent geologic analysis will be billed to you at a rate of $87 per hour. Sincerely, Ralph E.

Chevron Environmental Management Company 145 South State College Boulevard, 4th Floor Brea, California 92821 RE: BASELINE SITE ASSESSMENT Chevron Service Station No. 9-1536 2700 Oswell Street, Bakersfield, California SECOR Job No.: 04CH.91536.00 Dear Mr. Sigler: I I I I At the request and authorization of Chevron Environmental Management Company (Chevron), SECOR International Incorporated (SECOR) has completed a Baseline Site Assessment at Chevron Service Station No. 9-1536 located at 2700 Oswell Street in the City of Bakersfield, California (the Site). A Site Location Map is included as Figure 1 of the attached report. This Baseline Assessment was conducted in accordance with established Chevron guidelines for Property Transfer: Baseline Assessment Process. The purpose of the assessment was to obtain additional data on soil quality prior to the completion of a proposed property transaction. A brief discussion of the findings of SECOR's subsurface investigation and associated historical research for the Site and surrounding properties is presented in the following executive summary. EXECUTIVE SUMMARY I I I I Chevron Service Station No. 9-1536 is a retail gasoline service station. Internal Chevron records reviewed by SECOR show that an operating retail gasoline station has occupied the Site since at least 1968. The Site formerly had an open environmental case with the City of Bakersfield Fire Department (BFD) related to an unauthorized petroleum hydrocarbon release in soil discovered during the dispenser and product piping upgrade performed on August 23, 1995. The Site received closure on November 14, 1995. SECOR's subsurface investigation at the Site consisted of the completion of seven exploratory soil borings (BA-1 though BA-7) in the locations of existing underground storage tanks (USTs) and fuel dispensers, former partially assessed used oil UST, and one hydraulic lift. I I Soil sediment types encountered during SECOR's field investigation consisted primarily of fine- to coarse-grained sand and silt mixtures. Decomposed granite cobbles were encountered from approximately 15 to 20 feet bgs and at approximately 45 feet bgs. Gravel was encountered from approximately 30 to 45 feet bgs. Granitic bedrock was encountered in boring BA-2 at approximately 35 feet bgs. Groundwater was not encountered during the drilling activities. Regional groundwater flow direction is to the west. Chemical analysis of collected soil samples showed the presence of total petroleum hydrocarbons as L I I I I I I I I I I I I I I I I I I I Mr; Mark Sigler, P.E. October 9, 2003 Page 2 gasoline range organics (TPH-GRO) in two soil samples. TPH-GRO was detected at a maximum concentration of 890,000 micrograms per kilogram (~g/kg), in soil collected from boring BA-3, near the southwestern corner of the existing gasoline UST pad, at a depth of 40 feet bgs. The soil sample was subsequently analyzed for lead, which was detected at a concentration of 2.3 milligrams per kilogram (mg/kg). Benzene, methyl tertiary-butyl ether (MTBE), gasoline oxygenates (di-isopropyl ether [DIPE], ethyl tertiary butyl ether [EtBE], tertiary amyl methyl ether [TAME], tertiary butanol [TBA]), and ethanol were not detected above laboratory reporting limits in any soil samples analyzed. Total petroleum hydrocarbons as diesel range organics (TPH-DRO) and total petroleum hydrocarbons as oil range organics (TPH-ORO) were detected at maximum concentrations of 5.4 mg/kg and 59 mg/kg, respectively, in boring BA-4, near the location of the existing northwestern dispenser island and at the location of a former used oil UST, at a depth of 5 feet bgs. The sample was subsequently analyzed for volatile organic compounds (VOOs) and Title 22 Metals. VOCs were not detected above laboratory reporting limits. Detected metals were not reported at concentration of regulatory concern. Although station operation dates back to 1968, tank integrity reports for the Site date back to June of 1981. In December 1983, a product line leak was identified and 200 gallons of product were reportedly released. On February 1996, all fuel tanks failed pressure decay tests. In December 2002, the leak detector test results failed for all three tanks. On August 28, 2003, all fuel tanks and product lines were tested for divestment purposes. The fuel tank and product lines passed integrity testing and the monitoring system was tested and certified. Information provided by Environmental Data Resources, Inc. (EDR) shows that three active groundwater wells are located within 1-mile of the Site. EDR Well ID USGS0132312 is located ~ - 1 mile (2,640 feet to 5,280 feet) south southeast and upgradient of the Site. EDR Well ID USGS0132307 is located Y2 - 1 mile (2,640 feet to 5,280 feet) south southeast and upgradient of the Site. EDR Well ID 23383 is located Y2 - 1-mile (2,640 feet to 5,280 feet) east-southeast and upgradient of the Site. Colonel Nichols School was identified as a sensitive receptor. This school is located within 1/8- to 1/4- mile (960 feet to 1,320 feet) northwest (cross-gradient) of the Site. No facilities were identified from available records as having a potential release to the environment that could potentially affect soil and/or groundwater quality beneath the Site. A copy of this report is being forwarded to the City of Bakersfield Fire Department (CBFD), as per the request of the Chevron project manager Eric Roehl. The information presented in this report is valid as of the date our exploration was performed. Site conditions may alter with time; consequently, the findings presented herein are subject to change.

Seven exploratory soil borings (BA-1 though BA-7) were advanced Lmder SECOR's supervision on September 17 and 18, 2003, at the locations illustrated on attached Figure 2, Site Map. SECOR's work at the Site was conducted in general accordance with established Chevron guidelines for Property Transfer: Baseline Assessment Process. The purpose of the assessment was to obtain additional data on soil and groundwater quality prior to the completion of a proposed property transaction. 1.1 CURRENT AND HISTORIC SITE DESCRIPTION AND OPERATIONS I I Chevron Service Station No. 9-i 536 is a retail gasoline service station. The Site is located on the northwest corner of Oswell Street and Auburn Street in Bakersfield, California. Properties in the vicinity of the Site are commercial and residential in nature. Internal Chevron records reviewed by SECOR show that an operating retail gasoline station has occupied by since at least 1968 (Standard Oil Company of California, Western Operation, Inc. [Standard Oil], 1968). I I I The most current Ground & Grade Plan, provided by Chevron Environmental Management Company (Chevron) is dated September 2, 1988. The drawing shows three 10,000-gallon single-wall Owens/Corning underground storage tanks (USTs) containing various grades of unleaded gasoline, double-wall fiberglass product and vapor recovery lines, two fuel dispenser islands with two dispensers each, a station building, and a utility building at the northwest corner of the Site. The fuel USTs are located at 'the northeastern corner of the Site. The station building is 'aligned east to west near the center of the Site. Thebuilding appears to be a convenience store with a sales area and cashier's box, a walk- in cooler, a stock/utility room, and restrooms. The two dispenser islands are also aligned east to west on the north and south sides of the building (Chevron, 1988; revised 1992, 1996). According t_o a site survey plan dated June 12, 1968, the Site was undeveloped at the time of the survey (Hull and Moreland, 1968). zl I The original Site configuration included a building near the center of the property, three fuel USTs (one 5,000-gallon tank and two 10,O00-gallon tanks) located in the same general location and in the same general north/south alignment as the existing tanks. Two dispenser islands, aligned north to south, are shown south/southeast of the USTs. Each of the islands had three dispensers. The rectangular station building, an automotive service center, was centrally located on the property and oriented in a north/south direction. A 1,000-gallon exterior used oil UST was located on the northwest corner of the building. The UST was connected to a waste oil sump inside the building by a 2-inch-diameter waste oil line. Two underground hydraulic lifts were located inside the garage area of the building (Standard Oil, 1968). A second Site configuration included an additional'dispenser island and a pay booth. A small dispenser island including one dispenser was located north of the easternmost island. The pay booth was located south of the eastern dispenser islands. All three islands were aligned north to south. The second Site configuration was observed in an August 1987 Topographic & Boundary Survey map made by an independent surveyor (License No. 4545), on behalf of Chevron U.S.A. Inc. The name of the surveyor, whose signature and credentials appear on the, are illegible (Chevron, 1987). I I I I I I I I I I I I The locations of current and known previous surface and subsurface structures on the Site are illustrated on attached Figure 2. 1.21 REGIONAL AND LOCAL GEOLOGY The Site is located in the Great Valley Province, which extends approximately 650 miles from Red Bluff to Bakersfield and averages 50 miles in width from the Coast Ranges to the Sierra Nevada. The Sacramento Valley occupies the northern third of the province and the San Joaquin Valley the southern two thirds. The province comprises the quaternary and tertiary sediments from the Younger and Older Alluvium that overlie the early Tertiary to Jurassic Great Valley Sequence, which overlies the Sierra Nevada Crystallin'e rocks (Harden, 1997). More specifically, the Site is situated in the southern area of the San Joaquin Valley and the San Joaquin Basin along the Kern River floodplain. 'Beneath the general area of the Site lie the Younger Alluvium deposits, which lie over the Kern River Formation deposits underlain by the Etchegoin Formation deposits of Pleistocene and Pliocene Age. The Etchegoin Formation lies unconformably on top of a series of tertiary formations lying unco. nformably and conformably from the Chanac FOrmation to the Great Valley Sequence Formations (Harden, 1997). Soil sediment types encountered beneath the Site consist primarily of soils encountered consisted of fine- to coarse-grained sand and silt mixtures.. Decomposed granite cobbles are present from approximately 15 to 20 feet bgs and at approximately 45 feet bgs. Trace to some gravel was encountered from approximately 30 to 45 feet bgs. Granitic bedrock may be present at approximately 35 feet bgs. 1.3 REGIONAL AND LOCAL HYDROGEOLOGY The Site is located within the Kern Groundwater Basin located in the San Joaquin Basin groundwater region. The Tulare and Lake Groundwater Basins bound this basin to the north, the Sierra Nevada to the east and south, and the coastal ranges to the west and south (DWR, 1997; SJGS, 2000), More specifically, the Site is located within the Kern River Alluvial Fan (Kern Fan) of the Kern Basin. The Kern Fan is composed of Pleistocene to Recent sands sand and gravel deposits at the foot of the Sierra Nevada foothills and is saturated with bicarbonate-rich groundwater within the upper 200 feet of the fan. Aquifer thicknesses in the Kern Fan range from 500 and 3500 feet. Arsenic occurs naturally in the Kern Fan, derived from the erosion processes from the Sierra Nevada sediments of granitic and volcanic rocks as moving groundwater dissolves the rocks and liberates the arsenic~(SJGS, 2000). In Bakersfield, the Kern River Alluvial Fan is divided into the Buttonwillow depocenter at the north and the Tejon/Maricopa depocenter at the south by the Bakersfield Arch subsurface ridge (SJGS, 2000). The Site is located within the Tejon/Maricopa depocenter, approximately 2 miles southeast of the Kern River. Groundwater beneath the site is estimated to be present at approximately 200 feet below groundwater surface (bgs) (DWR, 2000). Regional groundwater flow beneath the site is eXpected to be toward the west. 1.3.1 Groundwater Production Wells Information provided by Environmental Data Resoumes, Inc. (EDR) shows that one three active groundwater wells are located within 1-mile of the Site. EDR Well ID USGS0132312 is located Y2- to 1 mile (2,640 feet to 5,280 feet) south southeast and upgradient of the Site. EDR Well ID USGS0132307 is located ~- to 1 (2,640 feet to 5,280 feet) mile south southeast and upgradient of the Site. EDR Well ID 23383 is located Y2- to 1-mile (2,640 feet to 5,280 feet) east-southeast and upgradient of the Site. 2 ! ! I I '1 I I I I I I I I I I I I I, I Additionally, according to the California Department of Water Resources (DWR), no state water wells are present within 1 mile (5,280 feet) of the Site. Please note that SECOR staff did not conduct field reconnaissance of the above mentioned groundwater wells. As such, detail as to the exact location of the wells is approximate. -3 I I I I I I I I I I I I I I I I I I I 2.0 SITE BACKGROUND INFORMATION 2.1 PREVIOUS woRK On July 14, 1988, Krazan & Associates, Inc. (Krazan) cOllected soil samples during removal of a used oil 'UST and the gasoline product lines. Soil samples were collected after removal of the structures under the Supervision of the Kern County Environmental Health Department. Ten samples were collected from the product lines and dispenser islands and were analyzed for total petroleum hydrocarbons (TPH) and ben;~ene, toluene, ethylbenzene, and total xylenes (BTEX) and isopropylbenzene by the California Department of Health Services (DOHS) Method. Samples were also collected from the used oil tank pit at depths of 2 feet bgs and 6 feet bgs. Used oil .tank pit samples were analyzed for total volatile hydrocarbons as oil and grease and total organic halides (TOX) by an unknown method and for Title 22 metals. TPH, benzene, and isopropylbenzene were detected at maximum concentrations of 483.86 parts per million (ppm), 0.7 ppm and 10 pprn, respectively, in sample 2B collected near the center of the westernmost dispenser island, at a depth of 6 feet bgs. Oil and grease and lead were detected at maximum concentrations of 2,825 ppm and 5.45 ppm, in the sample collected at six feet bgs (Krazan, 1988). On August 23, 1995, Groundwater Technology Inc. (GTI) collected soil samples during dispensers and product piping upgrades. At that time, the station had three 10,000-gallon "thick wall" fiberglass USTs, reportedly installed in 1988 (GTI, 1995). A total of 16 soil samples were collected from eight sample points under the direction of the Bakersfield City Fire Department. The samples were analyzed for total petroleum hydrocarbons as gasoline (TPHg) by the DOHS Method and for BTEX by the Environmental Protection Agency (EPA) Method 8020. TPHg was detected at a maximum concentration of 13 milligrams per kilogram (mg/kg) in sample P2 collected near the southeastern dispenser island, at a depth of 2 feet bgs. Benzene"was not detected above the laboratory detection limits (GTI, 1995). In a letter dated November 14, 1995, the City of Bakersfield Fire Department granted case closure'in association with the "dispenser replacement" (CBFD, 1995). 2.2 TANK INTEGRI'rY AND HISTORICAL SPILL/LEAK INFORMATION Although station operation dates back to 1968, tank integrity reports for the Site date back to June of 1981. A brief synopsis of the reviewed tank integrity testing data for the Site is outlined below: · On December 13, 1983, a leak was reported from a product line; 200 gallons of product are reported missing. · On January 21,1987, a 1,000-gallon used oil tank failed testing. The tank was retested on March 3, 1987, and found to be "mathematically tight". · On February 6, 1996, all three tanks (manifold underground) failed pressure decay tests given that-the PN vent caps on the super and plus vents were not holding 2 inches of water column. · On September 27, 2001, Dispenser 4 (plus) experienced wet failure. A defective nozzle was replaced. · On May 5, 2002, dispenser pans 3/4 and 7/8 and the mid-grade and supreme fill sumps failed testing. The fill sumps were repaired the same day. · On December 27, 2002, leak detector test results failed for all three tanks. I I I I I I I I I I I I I I On AugUst 28, 2003, all fuel tanks and product lines were tested for divestment purposes. The fuel tank and product lines passed integrity .testing and the monitoring system Was tested and certified. 5 '1 I I I I I I I I I I I I I I I /I 3.0 REGULATORY AGENCY DATABASE SEARCH 3.1 ENVIRONMENTAL DATA RESOURCES REPORT SECOR contracted with EDR to review databases maintained by various federal and state environmental agencies, The purpose of the review was to identify reported listings for the subject Site or other properties in the vicinity.

Per ASTM standards, a minimum of two historical record resources should be' researched to investigate possible past use of a given property. Potential historical records used for research might include historic aerial photography, topographic maps, fire insurance maps, city directories and/or prior environmental reports. Prior environmental reports, if applicable to the subject property, have been summarized in Section 2.0 of this report. Results of SECOR's other historical research for the subject Site are outlined in the following sections. 4.1 AERIAL PHOTOGRAPH REVIEW Aerial p. hotographs for the property and surrounding areas were obtained from EDR to evaluate historical usage of the Site and adjacent properties. The photographs were also reviewed to evaluate any diScernible evidence of potential sources of negative environmental impact at the Site and from neighboring properties. The general activity on a property and land use changes can often be discerned from the type and layout of structures visible in aerial photographs and maps; however, specific elements of a site operation cannot normally be determined. The following aerial photographs of the Site and surrounding areas were examined: · 1952 · 1961 · 1972 · 1984 · 1993 1952 The Site and Surrounding properties are undeveloped and a dirt road running north-south is located at the east end of the property. The Site exhibits relief topography. 1961 The Site and surrounding properties to the east and south are undeveloped. Surrounding properties to the north and west appear residential in nature. A dirt road running north south is located at the east end of the property.. The Site has shows a level graded relief. 1972 A T-shaped structure that appears to be configured as a gasoline station is present at the Site (in accordance with Chevron records). Adjacent properties to the east and south appear to be occupied by commercial structures (small rectangular and irregular shaped buildings). Adjacent properties to the north and west are undeveloped. A property that appears to be occupied by a school is present approximately 2400 feet (N-mile to Y¢-mile [1,320 feet to 2,640 feet]) northwest of the Site. 1984 A T-shaped structure that appears to be configured as a gasoline station is present at the Site (in accordance with Chevron records). Adjacent properties to the north and east appear to be occupied by 12 I I I I I I I I I I I II I I I I I I commercial structures. The adjacent property to the west appears to be a parking lot. The adjacent property to the south appears to be occupied by commercial buildings (tall square building). A property that appears to be occupied by a school is present approximately 2400 feet (N-mile to Y2- mile [1,320 feet to 2,640. feet]) northwest of the Site. Two properties appear to be occupied by two schools each, are present approximately 2700 feet (Y2-'to 1 mile[2,640 feet to 5,280 feet]) south of the Site. 1993 The'Site appears to be reconfigured. One rectangular structure exists on the Site at the place of the previous T-shaped structure. Surrounding properties are unchanged from the 1984 paragraph. Summary The uses of the Site and surrounding properties, determined from aerial phot'ograph review, did not appear to be. of environmental concern. 4.2 TOPOGRAPHIC MAP REvIEw Historical United States Geological Survey (USGS) topographic maps were reviewed by SECOR to identify past physiographic features such as streams, lakes, and Site and vicinity development.

The methods and procedures were conducted in general accordance with established Chevron Guidelines for Property Transfer: Baseline Assessment Process, except where indicated otherwise. " 5.1 FIELD OPERATIONS SECOR staff supervised the drilling of seven exploratory soil borings (BA-1 through BA-7) at the Site. On September 17, .2003, BC2 Environmental Drilling (Bc2) of Fullerton, California drilled four soil borings (BA-1 through and BA-4) using a CME 75 hollow-stem auger rig. BA-1 was advanced vertically to 58 feet bgs (maximum explored depth). Borings BA-2 through BA-4 were advanced to 40 feet bgs linear depth (approximately 35 feet bgs vertical) at an angle of 30 degrees from vertical. On September 18, 2003, BC2 drilled borings BA-5 and BA-6 using a hollow-stem auger rig to a' maximum explored depth of approximately 40 feet bgs linear depth (approximately 35 feet .bgs vertical) at an angle of 30 degrees from vertical. BC2 hand-augered boring BA-7 to a maximum explored depth of 8 feet bgs. The locations of the borings are shown on attached Figure 2. A copy of the.Site-Specific Health and Safety Plan is included in Appendix C. Underground Service Alert was notified prior to commencing drilling activities to identify any public utility alignments that may have been in potential conflict with the proposed borings. SECOR also provided the services of a geophysical survey company to identify any private utility alignments that may have been in potential conflict. In accordance with established Chevron Guidelines, SECOR staff supervised the clearing of soils from the upper five feet of soil at each boring location. An air-knife and vacuum extraction device was used to clear hollow-stem auger soil'borings, and a hand auger was used to clear the hand auger boring. A copy of the completed Boring Clearance Form is attached as Appendix D. Drilling activities included soil sampling and classification, and soil bOring abandonment. The following sections describe each of the elements of the completed Baseline Assessment investigation. 5.1.1 Drilling, Soil Sampling and Procedures During hollow-stem auger advancement sampling of encountered subsurface soils was performed using a California-modified split-spoon sampling device sleeved with three 6-inch long brass tubes. Soil samples were collected in the brass sleeves at five-foot intervals. At each sampling interval, the sampler was driven into undisturbed soil beyond the cutting head of the lead auger with a 140-pound hammer free falling from 30 inches until 18 inches of penetration was achieved or until the number of blows required to drive the sampler six inches (blow count) exceeded 50. Upon aSvancement of the sampler to the full 18- inch length or refusal depth, the augers were advanced around the sampler, and the sampler was brought to the surface. The sampling and drilling sequence was then repeated for the entire depth of each boring. Upon extracting the sampler at each depth interval, the soils contained therein were visually examined by SECOR field personnel who then classified the soils in accordance with the Unified Soils Classification System (USCS). A field photo-ionization detector (PID) was also used to monitor the VOC vapor in the 15 collected'soil. A summary of the USCS classifications and VOC vapor readings obtained are presented in the boring logs included as Appendix E. After USCS classifiCation and VOC evaluation, the soil samples collebted at each sampling interval Were packaged .by placing Teflon sheets over the ends of the lowermost or middle brass tube and capping the tube with a tight fitting plastic cap, labeled, and placed in an ice-filled cooler pending delivery under Chain-of-Custody protocol to a laboratory for potential chemical analysis. The Chain-of-Custody records for the soil 'samples c611ected from the borings are presented in Appendix F. 5.1.2 . Boring Abandonment Procedures Following soil sampling, soil borings BA-1 through BA-6 were abandoned by pumping bentonite grout from the bottom of the borehole to four feet below grade. From four feet for one foot below grade, granular bentonite or bentonite chips were placed and hydrated by introducing water in the borings. Soil boring BA-7 was abandoned by introducing granular bentonite inside the borehole, and the bentonite granules were hydrated by placing water in the boring from the b~ottom of the borehole to one foot below grade. Once the level of the sealing mixture had reached a level of approximately one foot below ground surface for all borings, redi-mix concrete was emplaced and finished flush with existing surface grade. 5.1.3 Equipment Cleaning Procedures/Containment of Materials To maintain quality control during drilling operations, the sampling equipment was cleaned in an Alconox scrub solution and double-rinsed first in tap water followed by a final rinse using distilled water prior to each sampling interval. All waste generated Was stored in a labeled 55-gallon steel drum on the property pending profiling for off site disposal at a licensed receiving facility. Decontamination water was combined with solid waste at a moisture level that did not exceed 20 percent (%) moisture per drum. 5.1.4 Laboratory Testing Program All soil samples collected during this investigation were delivered under Chain-of-Custody protocol to Del Mar Analytical (Del Mar), located at 2852 Alton Avenue, Irvine, California. Del Mar is certified to perform hazardous waste testing by the State of California. Soil samples were analyzed for total petroleum hydrocarbons as gasoline (TPH-GRO C,~-C~2) by gas chromatography/mass spectrometry (GC/MS) and for BTEX, MTBE, gasoline oxygenates (di-isopropyl ether [DIPE], ethyl tertiary butyl ether [EtBE], tertiary amyl methyl ether [TAME], tertiary butanol [TBA]) and ethanol by EPA Test Method 8260B. The sample with the highest GRO concentration was also analyzed for to. tal lead using EPA Test Method 6010. Soil samples collected in the vicinity of the former hydraulic lift were analyzed for total extractable petroleum hydrocarbons (TEPH) as gasoline, diesel, and oil range organics (TPH-GRO, TPH-DRO, and TPH-ORO, respectively) bY EPA Test Method 8015M. Soil collected near the former used oil UST was analyzed for TPH-GRO, TPH-DRO, and TPH-ORO by EPA Test Method 8015M. The sample with the highest TEPH concentration was analyzed for VOCs by EPA Test Method 8260B and for Title 22 Metals by EPA Method 6000/7000 series. 5.2 INVESTIGATION-DERIVED WASTE Twenty-one drums of investigation-derived waste (IDW) were generated as a result of drilling activities. Liquid waste generated was minimal and was combined with solid waste not to exceed 20% moisture in 16 drums. Profile paperwork forthe IDW stream has not been approved yet. Once it is provided, the profile numbers and manifests will be submitted to Chevron under a separate cover. 17 6.0 INVESTIGATION FINDINGS The results of the investigation are presented in the following subsections.

The Site is located on the northwest corner of Oswell Street and Auburn Street in Bakersfield, California. Properties in the vicinity of the Site are commercial and residential in nature. SECOR's review of available internal Chevron documentation for the Site Shows that the service station has been in operation since 1968. · Internal Chevron documentation shows that three generations of station facilities may have existed at the Site. The most current Ground & Grade Plan, provided by Chevron is dated September 2, 1988. The drawing shows three 10,000-gallon single-wall Owens/Corning USTs containing various grades of unleaded gasoline, double-wall fiberglass product and vapor recovery lines', two fuel dispenser islands with two dispensers each, a station building, and a utility building at the northwest corner of the Site. The fuel USTs are located at the northeastern corner of the Site. The station building is aligned east to west in the approximate center of the Site. The building appears to be a convenience store with a sales area and cashier's box, a walk-in cooler, a stock/utility room, and restro0ms. The two dispenser islands are also aligned east to west on the north.,and south side of the building (Chevron, 1988; revised 1992, '.1996). According to a site survey plan dated June 12, 1968, the Site was undeveloped at the time of the survey (Hull and Moreland, 1968). The original Site configuration included a build!ng approximately at the center of the property, three fuel USTs, two dispenser islands (three dispensers per island), an automotive service center and one 1,000~ gallon exterior used oil UST. Two underground hydraulic lifts were located inside the garage area of the building (Standard Oil, 1968). A second Site configuration included an additional dispenser island and a pay booth to the original Site configuration. The small dispenser island including one dispenser was located north of the easternmost island. The pay booth was located south of the eastern dispenser islands. All three islands were aligned north to south. The second Site configuration figured in an August 1987 Topographic & Boundary Survey · map made by an independent surveyor, on behalf of Chevron U.S.A. Inc. (Chevron, 1987). Although station operationdates back to 1968, tank integrity reports for the Site date back to June of 1981.. In December 1983, a product line leak was identified and 200 gallons of product were reported missing. On February 1996, all fuel tanks failed pressure decay tests. On December 2002, the leak detector test results failed for all three tanks. On August 28, 2003, all fuel tanks and product lines were tested for divestment purposes. The fuel tank and product lines passed integrity testing and the monitoring System was tested and certified. Information provided by EDR shows that one three active groundwater wells are located within 1 -mile of the Site. EDR Well ID USGS0132312 is located ~,~ - 1 mile (2,640 feet to 5,280 feet) south southeast and upgradient of the Site. EDR Well ID USGS0132307 is located Y2 - 1 mile (2,640 feet to 5,280 feet) south southeast and upgradient of the Site. EDR Well ID 23383 is located Y2 - 1 -mile (2,640 feet to 5,280 feet) east-southeast and upgradient of the Site. Colonel Nichols School was identified as a sensitive receptor. This school is located within 1/8- to N-mile (660 feet to 1,320 feet) northwest of the Site. No facilities were identified from available records as having a potential release to the environment that could potentially impact soil and/or groundwater quality beneath the Site. 21 SECOR's subsurface investigation at the Site consisted of the completion of seven exploratory soil bo_rings (BA-1 though BA-7) in the locations of existing unassessed underground storage tanks, former and existing fuel dispenser islands, former partially asseSsed used oil UST, and former hydraulic lifts. Boring locations are illustrated on Figure 2 of the attached report. 'Soil sediment types encountered during SECOR's field investigation consisted primarily of fine-to coarse- grained sand and silt mixtures to the maximum explored depth of approximately 58 feet bgs. Chemical analysis of collected soil samples showed the presence of total petroleum hydrocarbons as gasoline range organics in two soil samples. TPH-GRo was detected at a maximum concentration of 890,000 ~Lg/kg, in soil collected from boring BA-3, near the southwestern corner of the existing gasoline UST pad, at a depth of 40 feet bgs. The soil sample was subsequently analyzed for lead, which was detected at a concentration of 2.3'mg/kg. Benzene was not detected above laboratory reporting limits in any soil samples analyzed. MTBE, the gasoline oxygenates and ethanol were not detected above laboratory reporting limits in any soil samples analyzed. TPH-DRO and TPH-ORO were detected at maximum concentrations of 5.4 mg/kg and 59 mg/kg in the soil sample collected from boring BA-4, at a depth of 5 feet bgs, near the location of the existing northwestern dispenser island and at the location of a former used oil usm. The sample was subsequently analyzed for VOCs and Title 22 Metals. VOCs were not detected above laboratory reporting limits. Nine Title 22 Metals were detected above laboratory detection limits, but below regulatory concern. TPH-ORO was also detected in the soil samples from boring BA-7, at concentrations of 2.8 mg/kg and 6.5 mg/kg, at depths of 5 and 8 feet bgs, respectively, near the former hydraulic lift. 22 I I I I I I I I I I I I I I I I 8.0 LIMITATIONS SECOR has prepared this report for the exclusive use of Chevron as it pertains to Service Station No. 9-1536 located at 2700 Oswell Street in Bakersfield, California.

Elevations have been determined from the USGS Digital Elevation Model and should be evaluated on a relative (not an absolute) basis. Relative elevation information between sites of close proximity should be field verified. EDR's definition of a site with an elevation equal to the target property includes a tolerance of +/- 10 feet. Sites with an elevation equal to or higher than the target property have been differentiated below from sites with an elevation lower than the target property (by more than 10 feet).

NFRAP sites may be sites where, following an initial investigation, no contamination was found, contamination was removed quickly without the need for the site to be placed on the NPL, or the contamination was not serious enough to require Federal Superfund action or NPL consideration. EPA has removed approximately 25,000 NFRAP sites to lift the unintended barriers to the redevelopment of these properties and has archived them as historical records so EPA does not needlessly repeat the investigations in the future. This policy change is part of the EPA's Brownfields Redevelopment Program to help cities, states, private investors and affected citizens to promote economic redevelopment of unproductive urban sites.

Section 7.2.3 requires that a current USGS 7.5 Minute Topographic Map (or equivalent, such as the USGS Digital Elevation Model) be reviewed. It also requires that one or more additional physical setting sources be sought when (1) conditions have been identified in which hazardous substances or petroleum products are likely to migrate to or from the property, and (2) more information than is provided in the current USGS 7.5 Minute Topographic Map (or equivalent) is generally obtained, pursuant to local good commercial or cuStomary practice, to assess the impact of migration of recognized environmental conditions in connection with the property. Such additional physical setting soumes generally include information about the topographic, hydrologic, hydrogeologic, and geologic characteristics of a site, and wells in the area. Assessment of the impact of contaminant migration generally has two principle investigative components: 1. Groundwater flow direction, and ~ 2. Groundwater flow velocity. Groundwater flow direction may be impacted by surface topography, hydrology, hydrogeology, characteristics of the soil, and nearby wells. Groundwater flow velocity is generally impacted by the nature of the geologic strata.

Subcontractor/Contractor's employees will be trained by their employer in site-specific evacuation/emergency procedures, including alarm systems and evacuation plans and routes. The Subcontractor/Contractor shall instruct its employees that in the event of an emergency such as a fire, release, or accident involving injuries, they are required to dial 9~. The rep01ting employee is to state the problem clearly and fldly and remain on the line until dismissed by the operator. SECOR staff and Subcontractor/Contractors working ill an area where an emergency exists shall evacuate to a safe location, preferably upwind, away from tile area and take attendance. The ~athering location will be determined by the SHSO npon his/her arrival on site. It is the responsibility of tile SHSO to annotate the Site Plan with the Gathering Location anti to disseminate its position tinting tile Daily Prodnction SafeW Meeting. (If the emergency causes the route to a gate surrounding the site to be closed, the SECOR stclff and Subcontractor/Contractors shall move to an open area upwind of the hazard area, and remain there until instructed by emergency response personnel (i. e., police, fire, ambulance, paramedics, etc.) to do otherrvise.) Snbcontractor/Contractor has the responsibility to account for its own employees and to provide such information immediately to emergency response personnel upon request. SECOR staff and Subcontractor/Contractor may not reenter the emergency site without specific approval fi'om elnergency response personnel. In the event of fire ignition in close proximity to SECOR staff and Subcontractor/Contractor's employees, those persons shall evacuate the area and notify emergency personnel unless the fire is readily extinguished with pop-table dry chemical equipment on-hand. When in doubt, emergency response personnel shall be notified. 6.0 BACKGROUND INFORMATION ON THE PROJECT SITE Documeots provided by Chevron indicate that tile Site has been occupied by an operating retail gasoline s~ation from approximately 1968. During that time, piping and dispensers appear to have been upgraded bvice (in 1995 and 1998), and a used oil UST was removed in 1988. The filel USTs appear to have been upgraded in 1988, but reports documenting tank replacement and confirmation'sampling were not provided to SECOR. G!i~i~tblaiB~ Chevron Products Company SECOR Project No.04CH.91536.00 SECOR International Incorporated I I I I I I I On. July 14, 1988, Krazan & Associates, Inc. (Krazan) collected soil samples during removal of a used oil UST and the gasoline product lines. Soil samples were collected after removal of the structures trader the supervision of the Kern County Environmental Health Department. All ten samples collected fi-om the product lines and dispenser islands were analyzed for total petroleum hydrocarbons (TPH) by the California Departlnent of Health Services (DOHS) Method and for purgeable arolnatics (including benzene, toluene, ethylbenzene, and total xylenes [BTEX]). The two samples, collected fi'Oln the waste oil pit at depths of 2 feet bgs and 6 feet bgs were analyzed for oil and grease, total organic halides (TOX), and for Title 22 metals. Analytical results show moderate concentrations of petroleuln hydrocarbons in two samples (sample 2A at 2 feet bgs and sample 2B collected at 7 feet bgs) fi'om tile "product lines & dispenser island". Maximum concentrations were reported as 484 parts per million (ppm) TPH, 0.7 ppm benzene, 0.22 ppm toluene, 1.91 ppln ethylbenzene, 14 ppm xylenes, and 10 ppm isopropylbenzene. A inap attached to the report shows the sample location at the approximate center of the westernlnost island (Krazan, 1988). The samples collected from the used oil tank reportedly showed detectable levels of oil and grease (52 ppm and 2825 ppm), with the higher concentration detected in the sample collected at six feet bgs. Lead was reported in tile six-foot bgs sample at 5.45 ppm lead (Krazan, 1988). On August 23, 1995, Groundwater Technology Inc. (GTI) collected soil samples during dispensers and product piping upgrades. At that time, tile station bad three 10,000-gallon "thick wall" fiberglass USTs, reportedly installed ill 1988 (GTI, 1995). A total of 16 soil samples were collected fi'om eight salnple points under the direction of the Bakersfield City Fire Departlnent. The samples were analyzed for total petroleuln hydrocarbons as gasoline (TPHg) by the DOHS Method and for BTEX by EPA Method 8020. Two samples (P2-2 and P2-6), collected at the same location at different depths, reported target constituents at relatively low'concentrations: 13 milligrams get kilogram (mg/kg) TPH, 0.07 m~kg toluene, 0.06 mg/kg ethylbenzene, and up to 0.51 rog/kg xylenes (GTI, 1995). On November 14, 1995, the City of Bakersfield Fire Department submitted a "closure" letter in association with the" ' " dlspenser replacelnent . 7.0 CLIENT SAFETY PROCEDURES See Attachment 1. 8.0 SITE PLAN Site Plan is included in Attachment 2. ¢!i~gi:N~m~ Chevron Products Company SECOR Prqjecl No.04CH.9 t 53 6.00 7 SECOR International Incorporated I I I I I I I I m m m m m m m m m m m m m m mm m m m m 9.0 GOVERNMENT AND LINE LOCATOR CONTACT NAMES AND PHONE NUMBERS AGENCY or LINE NAME TELEPHONE NO.

This plan must consider: Level of traffic activi~ on a site andprovidefor the safcO; of all workers on the site. E.g., a gasoline site that is open to thepublic shozdd require sawhorse barricades to protect workers. Cones a~d caz~tion tape have proven ineffective in a mtmber ofsitztations.

It is also the responsibility of the SIISO to disseminate the Traffic Guidance and Control information to all site personnel during the Daily Production Safety Meeting and any other time as necessary. Work on this project will be conducted during the hours: 0600 - 1800, Monday - Friday. Shutoff valves/switches for utilities and products: It is the responsibility of the SHSO to annotate the Site Plan with the location of all shutoff valves and switches and to disseminate that information to all site personnel during the Daily Production Safety Meeting and any other time as necessary Jeweh-y safety: Jewelry can be dangerous. Large ear rings, long necklaces, loose-fitting bracelets, rings, watches, etc. can become entangled in machinery and cause removal of limbs, as well as be conductive of electricity.

"Zero Tolerance for Incident of ANY Kind. Work Together to Ensure A SAFE and High Quality Project This Health and Safety Plan has been developed for the purpose of informing SECOR employees of the hazards they are likely to encounter on the pro~ect site, and the precautions they should take to avoid those hazards. Sub-contractors and other contractors at the site must develop their own Health and Safety Plan to address the hazards faced by their own employecs. SECOR ]ms provided a copy of this Plan Io contractors in the interest of full disclosure of hazards of which we may be aware, and to satisfy SECOR's responsibilities under the OccupationaI Safety and Health Administration (OSHA) Hazard Communication standard. Similarly, contractors are required to inform SECOR of any bat.aMs of which they are aware or that the contractor's work on site might possibly pose to SF_L~R employees, including (but not limited to) the Material Safety Data Shce~s for chemicals the contractor may bring on-site. This plan should NOT be understood by contractors to provide information on ail of the baTards to which a contractor's employees may be exposed as a result of their work. I further certify that I have received training and medical surveillance accor~ding to the Health and Safety Plan and the OSHA Standard on Hazardous Waste Operations and Emergency Response (29 CFR 1910. I20): All parties conducting site ac6vities are requ/red to coordinate their activities and practices with the project SJte Health and Safety Officer. Your signature below confirms that you have read and understand the l~azards discussed in this Plan, and understand that sub-contractors and contractors must develop their own Health and Safety Plan for their employees. You also understand you could be prohibited by the Site Health and Safety Officer or other SECOR personnel from working on this project for not complying with any aspect of this Health and Safety Plan.

Results exceeded the linear range in the MS/MSD and therefore are not available for reporting. The batch was' accepted based on acceptable recovery in the Blank Spike (LCS). Analyte NOT DETECTED at or above the reporting limit or MDL, ifMDL is specified. Relative Percent Difference ADDITIONAL COMMENTS For 8260 analyses: Due to the high'water solubility of alcohols and ketones, the calibration criteria for these compounds is <30% RSD. The ayerage % RSD of all compounds in the calibration is 15%, in accordance with EPA methods. For HYdrocarbon Distribution Analyses: The reporting limits for the individual carbon distribution ranges are derived by proportioning the individual ranges relative to the total carbon range, not to fall below the method detection limit c~f the total range. For GRO (C4-C1~): GRO (C4-C12) is quantitated against a gasoline standard. Quantitation begins immediately following the ~nethanol peak. For Volatile Fuel Hydrocarbons (C4-C12): Volatile Fuel Hydrocarbons (C4-C12) are quantitated against a gasoline standard. Quantitation begins immediately before TBz For Extractable Fuel Hydrocarbons (EFH, DRO, ORO): Unless otherwise noted, Extractable Fuel Hydrocarbons (EFH; DRO, ORO) are quantitated against a Diesel Fuel Standard.
