UNDERGROUND STORAGE TANK CLEANUP FUND PROGRAM, NOTICE OF ELIGIBILITY DETERMINATION: CLAIM NUMBER 13505; FOR SITE ADDRESS: 2518 WHITE LN, BAKERSFIELD Your claim has been accepted for placement on the Priority List in Priority Class "D" with a deductible of$10,000. Compliance Review: After adoption of the Priority List, staff will review, verify, and process applications based on their priority and rank within a priority class. During this Compliance Review, staff may request additional information needed to verify eligibility, Once review of the application is complete and the claim is determined to be valid, a Letter of Commitment will be issued obligating funds toward the cleanup. After the compliance review, your claim may be rejected if Division staff determine that you have not complied with regulations governing site cleanup, you have not supplied necessary information or documentation, or your claim application contains a material error. In such event, you will be issued a Notice ofIntended Removal rrom the Priority List, informed ofthe basis for the proposed removal of your claim, and provided an opportunity to correct the condition that is the basis for the proposed removal. Your claim will be barred from further pantcipation in the Fund, however, if the claim application contains a material error resulting from fraud or intentional or negligent misrepresentation. Record keeping: During your cleanup project you should keep complete and well organized records of all corrective action activity and payment transactions. If you are eventually issued a Letter of Commitment, you will be required to submit: (1) copies of detailed invoices for all corrective action activity performed (including subcontractor invoices), (2) copies of cançeled checks used to pay for work shown on the invoices, (3) copies of technical documents (bids, narrative work description, reports), and (4) evidence that the claimant paid for the work performed (not paid by another party). These documents are necessary for reimbursement and failure to submit them could impact the amount of reimbursement made by the Fund. It is not necessary to submit these documents at this time; however, they will definitely be required prior to reimbursement. Compliance with Corrective Action Requirements: In order to be reimbursed for your eligible costs of cleanup incurred after December 2, 1991, you must have complied with corrective action requirements of Articl.e 11, Chapter 16, Division 3, Title 23, California Code of Regulations. Article 11 categorized the corrective action process into phases, In addition, Article 11 requires the responsible party to submit an investigative work plan/Corrective Action Plan (CAP) before performing any work. This phasing process and the workplan/CAP requirements were intended to: 1. help the responsible party undertake the necessary corrective action in a cost-effective, efficient and timely manner; California Environmental Protection Agency Ÿ Recycled Paper II ~ - e . Unocal Corp. -2- November 18, 1998 2. enable the regulatory agency to review and approve the proposed cost-effective corrective action alternative before any corrective action work was performed; and 3, ensure the Fund will only reimburse the most cost-effective corrective action alternative required by the regulatory agency to achieve the minimum cleanup necessary to protect human health, safety and the environment. In some limited situations interim cleanup will be necessary to mitigate a demonstrated immediate hazard to public health, or the environment. Program regulations allow the responsible party to undertake interim remedial action after: (1) notifying the regulatory agency ofthe proposed action, and; (2) complying with any requirements that the regulatory agency may set. Interim remedial action should only be proposed when necessary to mitigate an immediate demonstrated hazard. Implemelltillg illterim remedial actioll does IlOt elimillate the requirement for a CAP alld all evaluatioll of the most cost- effective corrective action alternative. Three bids and Cost Preapproval: Only corrective action costs required by the regulatory agency to protect human health, safety and the environment can be claimed for reimbursement. You must comply with all regulatory agency time schedules and requirements and you must obtain three bids for any required corrective action. Unless waived in writing, you are required to obtain preapprova1 of costs for all future corrective action work. If you do not obtaill three bids alld cost preapproval, reimbursemellt is IlOt assured alld costs may be rejected as ineligible.

GeoResearch Division October 11, 1996 Mr. Howard Wines Bakersfield City Fire Department 1715 Chester Avenue Bakersfield, Ca 93301 RE: Workplan for Verification Sampling and Site Closure Reporting Former Unocal Service Station No. 7048 2518 White Lane, Bakersfield, California PSI Project No. 574-6K004 Dear Mr. Wines On behalf of Unocal Environmental Remediation Services (Unocal), Professional Service Industries, Inc. (PSI) is pleased to present this workplan to conduct verification sampling and complete site closure reporting for the above-referenced site. The site is located within the City of Bakersfield, California, in the southeast quarter of the northwest quarter of Section 13 of Township 30 South and Range 27 East, MDBM (Figure 1). The site is identified by the Kern County Assessor Parcel Number 338-101-07. This work has been prepared to fulfill the requirements of the City of Bakersfield Fire Department (BFD). Approval of this workplan is required prior to implementation BACKGROUND The former service station was decommissioned in early 1992 and the underground fuel storage tanks (USTs), product lines, and dispensers were removed in September 1992 (GeoResearch, 1993a). A Phase II site investigation was conducted at the site in August 1993 (GeoResearch, 1993b). The purpose of the investigation was to determine the vertical and lateral extent of petroleum hydrocarbons that were identified at the site when the USTs and product lines were removed. In August 1995 a soil vapor extraction system (SVES) was installed at the site which consisted of four vapor wells, one bioventing well and one background well. SOIL REMEDIATION SYSTEM SUMMARY Operation of the SVES began in October 1995 and continued through June 1996, at which time the system was permanently shut down. The concentrations of volatile organic compounds (VOCs) in site soils have appeared to reach an asymptotic l1~formation To Build 011 PSI- 410 West FallbrookAvenue, Suite 105 - Fresno.

The site is presently fenced and unoccupied. All vapor extraction equipment has been removed with the exception of the vapor wells and conveyance piping. GEOLOGVHYDROGEOLOGY Soils beneath the site consist of alluvial material from the Sierra Nevada to the east and the Tehachapi mountains to the south. This heterogeneous section of Pleistocene and Pliocene alluvium is on the order of 5,000 feet thick in the Bakersfield area and is composed of unconsolidated sand, gravel, silt, clayey sand and sand. Pliocene- Pleistocene continental clastic deposits overlie the Tertiary basement. The Tertiary basement, composed of granitic and metamorphic rocks, underlies the clastic section at a depth on the order of 15,000 feet below ground surface. In the Bakersfield area, groundwater occurs primarily under unconfined and semi- confined conditions. Review of the Kern County Water Agency (KCWA) map entitled "Groundwater Surface Elevation Map, January 1993", shows a groundwater elevation contour at 200 feet above mean sea level in the vicinity of the site. Review of the 7.5 minute Gosford topographic map, photorevised 1974, indicates an elevation of approximately 375 feet near the site. Comparison of the two elevations indicates that groundwater in the vicinity of the site should occur approximately 175 feet below existing grade with a southwesterly flow direction. SCOPE OF WORK PSI proposes the following scope of work in accordance with the approved Workplan for Soil Remediation (GeoResearch, 1994). This scope of work will be conducted in three phases which include: PHASE 1 - VERIFICATION SAMPLING AND WELL ABANDONMENT 1. Three soil borings will be advanced for the collection of conformation soil samples. One soil boring will be drilled to an approximate depth of 25 feet beneath dispenser island #3 and two soil borings will be drilled to approximately 45 feet beneath dispenser island #1 (Figure 2). The soil borings will be within and around areas that have shown in previous investigations to contain high concentrations of hydrocarbons (GeoResearch, 1993b) to determine the effectiveness of vapor extraction and bioremediation in these areas. Soil samples will be collected at 5-foot intervals and e e Mr. Howard Wines PSI Project No. 574-6K004 October 11, 1996 Page 3 submitted to BC Laboratories, Inc. of Bakersfield, California. Representative samples collected will be analyzed for total petroleum hydrocarbons as gasoline (TPH-G) according to California Department of Health Services (DOHS) method; benzene, toluene, ethyl benzene and total xylenes (BTEX) according to Environmental Protection Agency (EPA) Method 8020 (island 1); and total petroleum hydrocarbons as diesel (TPH-D) according to DOHS method (island 3). The borings will be completed in accordance with standard PSI procedures (Attachment 1) under the direction of a State of California-Registered Geologist. The work will be completed in accordance with a site-specific health and safety plan. 2. Six wells (two dual-completed soil vapor extraction wells, one bioventing well and one background vapor well) will be abandoned. Well abandonment methods will include removing the well casing to a depth of approximately 5 feet below ground surface and filling each well with a bentonite sand/slurry mixture. All aboveground vapor conveyance piping will be removed. PHASE 2 - CLOSURE REPORTING A final soil remediation report will be prepared and submitted to the BFD. The report will include graphs, tables and figures summarizing the results of remedial system operation and a discussion of the soil confirmation sampling results.

Soil borings are advanced with a hollow-stem, continuous-flight auger. The size of the auger's outside diameter (00) is determined by the purpose of the boring. For soil sample collection or well installation, usually 8- or 1 Q-inch 00 augers are used. 2. The boring, if vertical, is advanced to a specified depth below ground surface. If the boring is slanted from vertical, the auger is placed at the specified angle to vertical and then advanced to a specified depth. 3. During drilling, a continuous log of the sediments is made by a hydrogeologist in accordance with the Unified Soil Classification System. 4. The auger lengths are steam-cleaned before advancing each boring to prevent intercontamination of borings. The rinsate resulting from cleaning will be stored on site in DOT-approved, 55-gallon drums. f:\public\document\fieldpro\soilborg,pro021 0941 L ""';; '" ,.; e e PSI PROCEDURES FOR SOIL SAMPLING DURING DRILLING The following paragraphs describe the PSI procedures for soil sampling during drilling, using hollow-stem, continuous-flight augers. 1. Soil samples are collected using a 2.0- to 2.5-inch inside-diameter, modified California split-spoon sampler. The sampler is lined with two to three 6-inch long, 2.0- to 2.5-inch diameter brass (or stainless steel) tubes for containment of the soil samples. 2. To avoid cross-contamination of samples, the sampler and rings are washed before each use with nonphosphate detergent and double rinsed with distilled water. 3. At the prescribed sampling interval of 5 feet, the sampler is attached to the drive rod and driven 18 inches into undisturbed soil below the lead auger with a 140-pound hammer that is repeatedly dropped from a 30-inch height. The number of drops is recorded during each 6-inch increment and used as a qualitative determination of soil consistency and density. 4. The lead, or deepest, tube is recovered from the sampler, sealed by taping aluminum foil or Teflon and plastic end caps on both ends, labeled, placed in a plastic sealable bag, and placed on ice or equivalent medium sufficient to maintain a sample temperature of less than 4 degrees centigrade until the samples are received by a certified hazardous waste laboratory. 5. The sample is recorded on a chain-of-custody form to document trackability of the sample. 6. The sampled interval is classified using the remaining tubes and described on a log of soil boring form, following the Unified Soil Classification System. f:\public\document\fieldpro\soilborg. pro021 0941 L .' . " é; e e PSI PROCEDURES FOR FIELD DOCUMENTATION OF SAMPLING ACTIVITIES The following paragraphs describe PSI procedures for proper sampling documentation. 1. Sampling procedures shall be documented in a field notebook that will contain the following information: · Sample collection procedures, · Date and time of collection, · Date of shipping, · Sample collection location, · Sample identification number(s), · Intended analysis, · Quality control samples, · Sample preservation, · Name of collector, · Any pertinent observations. 2. Samples shall be labeled with the following information: · Sample number, · Well number, · Date and time sample was collected, · Name of collector, and · Sample preservatives (if required). 3. Handling of the samples shall be recorded on a chain-of-custody form that will include the following information: · Site name, · Signature of collector, · Date and time of collection, · Sample identification number, · Number of containers in sample set, · Description of sample and container, · Names and signatures of persons, and the companies or agencies they represent, who are involved in the chain of possession, · Inclusive dates and times of possession, and · Analyses to be completed. f:\public\document\fieldpro\soilborg.pro021 0941 L ")1 TII1y 191\1 Date -.

As referenced in the workplan, the remediation shall proceed until routine monitoring indicates that the remediation technology has exhausted it's effectiveness. In the event confirmation sampling indicates that the technology has not been successful in reducing hydrocarbon concentrations, below state guideline levels other remediation alternatives shall be employed in order to accomplish the reductions to that secondary technology's maximum effectiveness (e.g. soil excavation and disposal). Therefore, this office will continue to require that each remediation technology be utilized to its maximum effectiveness IN ADDITION TO reducing hydrocarbon concentrations below the maximum allowable levels referenced in the LUFT manual. Please give this office 5 working days notice before work is actually scheduled to begin at this site. Sincerely, ~j¿f¿J~ 'V'.... - Howard H.

Unocal has a soil vapor extraction system which is currently operating at a site in Nevada and is expected to be available for installation at the subject site in April, 1995. Work will be initiated this month to permit this unit for use at the subject property through the San Joaquin Valley Unified Air Pollution Control District (APCD). Please note that the time required for permitting through the APCD can only be approximated and is out of our control. The tentative system start-up date is May 1, 1995. Your letter also mentions petroleum hydrocarbons in the soil exceed limits allowable by state guidelines. Please clarify what guidelines are referenced and what acceptable cleanup levels are required for both the gasoline and diesel plumes at the site. Should you have any question or further comments, please feel free to contact me at (510) 277-2311. Sincerely, ~C.Q Edward C.
