(P.G.A.) for the above-referenced facility has been reviewed. Only one (1) soil sample exhibited traces of contamination (sample #2-lA, toluene .013 ppm, ethyl benzene .008 ppm). The levels are below the action levels required by the Regional Water Quality Control Board. Therefore, our Department believes a "no action" mitigation option to be acceptable, with no further action required at this time. A Closure Letter will follow under separate cover.

County of Kern 2700 "M" Street, Suite 300 Bakersfield, CA 93301 Re: Highland High School Site Characterization Permit #: 090009 Dear Ms. Darling: A site characterization workplan for the above referenced site was submitted to the Environmental Health Services Department for your approval. Your response, dated January 22, 1991, consisted two comments regarding slant drilling and the fate of rinsate and spoils (copy attached). This letter contains responses to each comment and serves as an amendment to the original proposed work plan. Comment 1. In view of the increasing high levels of contamination present at the dispenser area and adjacent to Classrooms, a slant boring will be required to assess possible migration beneath the building. Response 1. Soil Boring #3 will be located approximately seven feet southwest of the dispenser and will be slant drilled approximately five feet to the northwest under the classroom (see attached revised Plot Plan). The bottom of the boring will be approximately due west of Soil Boring #2. Soil Boring #2 will be located in the center of the dispenser. Comment 2. Regarding storing and sampling for analysis and subsequent disposal of rinsate and drilling spoils, drill cutting"~and rinsate shall not be mixed before sampling separate sample analygis will be required before disposal. Response 2. Line two, paragraph one, Item 4.0 of the Quality Assurance/Quality Control Section (QA/QC Page 3) referring to rinsate is hereby eliminated. A sentence, "All rinsate will be placed into a Highland High SchOc .re Characterization 1/28/91 separate drum and analyzed for BTXE prior to disposal." is hereby added to the same paragraph in front of the last line beginning with the words, "Upon completion of laboratory analyses,.. ,." The last sentence in the same paragraph is amended to read, Upon completion of laboratory analyses,.l~Lt2~aLn~ will be transported by Laidlaw to a State approved hazardous waste disposal site." (changes underlined). If you feel it is necessary, we will be happy to meet with you in person to discuss the procedures outlined in our workplan and in the attached amendments to the work plan.

I believe it is the responsibility of the environmental contractor to locate any piping or other obstructions to drilling,slant or otherwise. In view of this it may be advantageous to move boring SB #3 closer to boring SB cf2 for the'slant boring and use boring SB cfl'for the southern horizontal limits. In any event, our Department will need more than an opinipn if the contaminant has spread beneath the classroom, (i.e.) a slant boring. Regarding storing and sampling for analysis and subsequent disposal of rinsate and drilling spoils, drill cutting and rinsate shall not be mixed before sampling - separate sample analysis will be required before disposal.

The State will then charge you, a responsible party, for both the costs incurred by the County and the State, pertaining to your site, under the State terms explained below: Whereas the Legislature has appropriated funds from the California Hazardous Substance Clean-up Fund to pay the local and state agency administrative and oversight costs associated with the cleanup of releases from underground storage tanks; and Whereas the direct and indirect costs of overseeing removal or remedial action at t he above site are funded, in whole or in part, from t he Hazardous Substance Cleanup Fund; and Whereas the above individual(s) or entity(les) have been identified as the party or parties responsible for investigation and cleanup of the above site; YOU ARE HEREBY NOTIFIED that pursuant to Section 25360 of the Health and Safety code, the Above Responsible Party or Parties shall reimburse the State Water Resources Control Board for all direct and indirect costs incurred by any and all state and local agencies while overseeing the cleanup of the above underground storage tank site, and the above Responsible Party or Parties shall make full payment of such costs within 30 days of receipt of a detailed invoice from the State Water Resources Control Board. (B) COUNTY OF KERN LOCAL AGREEMENT OPTION Kern County Environmental Health is providing this option fOr those who prefer to pay the County directly and avoid the addition of State costs. Prior to the County's performance of services, this option requires your deposit of $1,000.00 (one thousand dollars) with the County to be held in the Local Option Trust Account. Charges for County oversight are made against this account. In this option, a responsible party must enter into a County agreement, attachment "B". The environmental sensitivity (attachment "C") of this site has. been reviewed by Environmental Health to determine the potential threat for groundwater contamination. Only sites determined to be non-environmentally sensitive may enroll in the Local Option Agreement.

In such cases, Environmental Health will utilize the State contract to pay for County oversight activities. The,County of Kern reserves this right for any site even when the site is located in a non-environmentally sensitive area. It is necessary for you to respond, in writing, within ten (10) calendar days of receipt of this letter to advise Kern County Environmental Health of your choice: either the State contract or the County's Local Agreement Option.

LECOMMENDATIONS/GUIDELINES FOR REMOVAL OF UNDERGROUND STORAGE TANKS This department is responsible for enforcing the Kern County Ordinance Code, Division 8 and state regulations perlaining to underground storage tanks. ~,epresentatives from this department respond to job sites during tank removals to ensure that the tanks are safe to remove/close and that the overall iob performance is consistent with permit requirements, applicable laws and safety standards. The following guidelines are offered to clarify the interests tnd expectations for this department. 1. ' .lob site safety is one of our primary concerns. Excavations are inherently dangerous. It is the contractor's responsibility to know and abide by CAL-OSHA regulations. The job foreman is responsible for the crew and any subcontractors on the job...As a general rule workers are not permitted in improperly sloped excavations or when unsafe conditions exist in the hole. Tools and equipment are to be used only for their designed function. For example, backhoe buckets are never substituted for ladders. 2. Properly licensed contractors are assumed to understand the requirements cf the permit issued. The job foreman is responsible for knowing and abiding by the conditions of the permit. Deviation from the permit conditions may result in a stop-work order. 3. Indi¥iduai contractors will be held responsible for their post-removal paperwork. Tracking forms, hazardous-waste manifes:.s and analyses documentation is necessary for each site in order to close a case file or move it into mitigation. When contractors do not follow through on necessary paperwork, an unmanageable backlog of incomplete cases results. If this continues, processing time for completing new closures will increase.

Appendix A Appendix B Appendix C Logs of Soil Borings Laboratory Results Chain of Custody Documents Highland High 9/5/91 1.0 Introduction This report details site characterization studies conducted at Highland High School, 2900 Royal Scots Road, Bakersfield, California (Figure 1) on July 26th, 1991 by Pacific Geotechnical Associates, Inc. (PGA). The work was contracted by Kern High School District. The purpose of this work was to determine the vertical and lateral extent of product plume(s) resulting from a dispenser and gasoline tank site, (both of which had been removed), assess the potential environmental impact of the contamination and propose three remediation options which are compatible with the nature of the contamination plume and the surrounding cultural conditions at the site. This report contains background information regarding the site, a description of the study methodology, and subsequent findings. An evaluation with conclusions and recommendations for site remediation alte.matives are also discussed. The appendices to this report contain the logs of the exploratory soil borings, laboratory results and chain of custody records. 2.0 Project Description 2.1 Site History Inventory records indicate no loss from the tank prior to removal, but some staining' and petroleum odor was 'documented during the removal of the dispenser by McNabb Construction Company.. Soil samples taken two feet and six feet below center of the tank recorded no contamination. However, soil samples taken two and three feet from beneath the dispenser recorded 670 and 17,000 parts per million (ppm) Total Petroleum~ Hydrocarbons (TPH) respectively. The cause and quantity of release of product was unknown. The Kern County Environmental Health Services Department (KCEHSD) requested that a site characterization be conducted to further study the unauthorized release of product at this site. ~'- Pacific Geotechnical Associates, Inc. 1 Highland High Sc 9/$/91 3.0 Purpose and Scope 3.1 Introduction The purpose and scope of this study was to define the vertical and lateral extent of the product plume associated with the leaking dispenser located at the site and to ascertain if any product had reached the water table. The sampling program described below was folloWed to achieve this end. 3.2 Soil Sampling Procedures On July 26th, 1991, three exploratory soil borings were advanced at the locations shown in Figure 2. Soil boring #1 was located eleVen feet southwest of the dispenser, in the center of the tank excavation, and advanced 31.5 feet. Soil boring #2 was positioned two feet southwest of the dispenser and advanced 25.5 feet. Soil boring #3 was located eight feet southeast of the dipenser and advanced to 26 feet. Personnel of PGA supervised soil boring operations and collected and described samples for laboratory analysis. Drilling services were provided by Melton Drilling Company of Bakersfield, California. Soil boring locations were selected by PGA personnel based on previous field findings, and recommendations made by Flora Darling of the KCEHSD. The positions of the borings were later determined for mapping purposes using a measuring tape and Brunton compass. The soil borings were advanced using a Mobile Drill B-53 drill rig equipped with an 8-inch diameter, continuous flight, hollow stem auger. Samples were collected using a hammer driven, split spoon sampler ,lined with 2.5-inch by 6-inch brass rings. Soil boring #2 was continuously cored for stratigraphic control starting at two feet. Soil borings #1 and #3 'were alternately augered and cored for sampling at five foot intervals with the first sample taken at five feet. Soil descriptions were made by a geologist under the supervision of a registered geologists, and consisted of soil type, grain size, color, text. ure, sorting, inclusions, odor, and other distinguishing features. ~ A Foxborro Model 128/FID Organic Vapor Analyzer (OVA) detector was used to field screen samples for volatile organic compounds (VOC's).- This Pacific Geotechnical Associates, Inc. 2 Highland High Sc 9/5/91 measurement was recorded in parts per million (ppm) as methane, and was taken from a capped brass ring core sample which had been agitated and set in the sun to warm for several minutes. Samples selected for laboratory analysis had both' ends inspected for lithology and were then immediately sealed with laboratory tape, plastic covers and secured with duct tape. Each sample was labeled, placed in an ice Chest and maintained at 4 degrees Celsius until delivered to BC Laboratories in Bakersfield. Chain of Custody procedures were followed (see Appendix C). All samples were analyzed for benzene, toluene, xylene and ethylbenzene (BTXE), and total hydrocarbon (TPH) as gasoline using EPA methods 8020 and 5030 with a flame ionization detector (FID). The results of the analysis are presented in Appendix B and are summarized in Figure 3. The split spoon sampler and the brass tubes were washed with a non- phosphate detergent and rinsed with water between samples to insure quality control. Boring ceased when successive field screening measurements recorded zero ppm using the OVA. After the samples were obtained and the operations complete, the bore holes were filled with concrete. Spoils from the augered soil borings were placed in 55 gallon drums, sealed, labeled, and temporarily stored on site. After receiveing the laboratory results indicating no contamination, the spoils were transported to an authorized landfill. 4.0 Findings 4.1 Soil Profile As seen in Figure 3 and Appendix A, the soil profile generally consists of a sequence of clayey sand near the surface. Below the clayey sand is a conglomeratic strata containing alternating appreciable amounts of fines and little fines from nine to sixteen feet. Extending below sixteen feet consists prodominately of well sorted clean sands containing little fines. A lense of silty sand was encountered in soil boring #1 from approximately 17 to 26 :feet, underlain by well sorted clean sand. Pacific Geotechnical Associates, Inc. 3 Highland High S 915/91 The .highest OVA field screening values were recorded within the backfilled excavation, rather than beneath the dispenser. There was no sample recovery in soil boring g2 betWeen the depths of 8.5-14.5 feet due to large diamete~ cobbles. At 15.5 feet a dense conglomeratic layer with cobbles four inches and greater in diameter were encountered which refused any further advancement. Soil boring g2 was relocated two feet southeast of the original boring, and continuously augered to a depth, of · fifteen feet. Contiuous coring resumed in soil boring g2 at fifteen feet to total depth of 25.5 feet. A detailed description of the soils encountered in the borings is presented in Appendix A of this report. The laboratory analysis of soil samples are presented in Appendix B and summarized in Figure 3. An evaluation of the significance of these findings is presented in Section 5.0. 5.0 Evaluation 5.1 Introduction This section evaluates the findings of the investigation to better develop conclusions and recommendations regarding this site. The evaluation is based on the results of observations and laboratory data. The purpose and scope of. the investigation is to determine the vertical and horizontal extent of 'gasoline contamination, to ascertain if any product reached the groundwater, and to present options for appropriate remedial action. 5.2 Tank Site Soil boring gl was located in the center of the tank excavation and augered to a depth of 31.5 feet to characterize the lateral extent of product from the dispenser. Field analysis using the Organic Vapor Analyzer (OVA) recorded Volitile Organic Compounds (VOC's) of 2.4 ppm and 1.6 ppm at six and eleven ~.- feet respectively. Further field analysis recorded no contamination at fu~her depths. Laboratory analyses recorded no contamination detected in i~ny of the soil samples taken in soil boring gl. Pacific Geotechnical Associates, Inc. 4 Highland High 9/5/9 Soil borings #1 and #3 were used to determine lateral extent of product from the dispenser site. 5.3 Dispenser Site S6il borings #2 was augered to a depth of 25.5 feet and used to characterize the vertical extent of product associated with the dispenser. Field analyses using the OVA, detected no contamination throughout soil boring 02. Soil samples were obtained for laboratory analyses at approximately three foot intervals. Laboratory analyses recorded .013 ug/g and .008 ug/g of toulene and ethylbenzene respectively, at five feet below grade. Further laboratory analyses recorded no detectable levels of TPH as gasoline or BTXE. Soil boring #3 recorded no contamination in any field or laboratory analyses. 5.4 Groundwater .The 1989 Water Supply Report published by the Kern County Water Agency indicates that the depth to. groundwater in the Summer of 1989 was greater than 350 feet. Groundwater is not considered to be threatened. 6.0 Conclusions 6.1 Introduction The dispenser and tank location at Highland High School has been characterized for the vertical and horizontal extent of product associated with leakage. Three soil borings ranging in depth from 25.5 to 31.5 feet were advanced with all soil samples being analyzed for TPH as gasoline and BTXE. A plan view (Figure 2) and a cross sectional view (Figure 3) of the site characterization area are included in this report. 6.2 Findings Field screening measurements of VOC's in soil boring #1 recorded 2.4 ppm..and 1.6 ppm at six and eleven feet respectively. All other field screening measurements taken in the three explorator~ soil borings recorded zero (0) ppm. Pacific Geotechnlcal Associates, Inc. 5 Highland High 9/5/91 Laboratory analyses measured for TPH of gasoline, and benzene, toulene, xylene, and ethylbenzene. Results of the laboratory analyses recorded .013 mg/kg and .008 mg/kg for toulene and ethylbenzene respectively, at a depth of five feet in soil boring #2. All other laboratory results for soil sample anlyses taken in the three exploratory soil borings, recorded None Detected (ND) for the subject contaminants. 6.3 Risks Field observations and measurements, and laboratory analyses indicate that the site does not pose a present or reasonable threat to groundwater due to' this repons findings of predomintely None Detected and extremely low values of contaminants. 7.0 Remedial Action Options 7.1 Introduction Three remedial options are presented for the tank sites. These options take into consideration the following: The sites do not pose an immediate threat to groundwater. Potential. migration routes of the contaminants include downward migratiOn due to excessive percolation of surface waters' and upward migration of volatile vapors. Vapors from the sites could pose potential concerns. Supervision, testing and quality control for any of the mitigation alternatives has not been included in these cost analyses. These estimates have been developed only for providing a general comparison between the three alternatives and should not be used for preliminary budgeting purposes. 7.2 Option 1/ No Action (Natural Biodegradation) No remedial action will be taken. The dispenser and tank sites wilF' be resurfaced to meet the~ needs of the maintenance yard. Pacific Geotechnical Associates, Inc. 6 Highland High 9/519! Concentrations of contaminants will decrease with time due to; 1) the removal of the sources of product and 2) natural biodegradation processes which are already active. The time required for TPH gasoline and BTXE concentrations to be reduced significantly or to non-detectable levels in the soil 'cannot be known. Containment by surficial concrete and asphalt may isolate contaminant vapors from human activity. A notice will be posted near the dispenser location informing the public that gasoline contaminated soil is present beneath the driveway, and where information concerning the contamination can be found. This option is feasible and will cost $150 or less to implement. 7.3 Option 2/ Passive Ventilation The tank site will be resurfaced to meet the needs of the school maintenance. area. The dispenser and tank sites will be ventilated to reduce the hazard associated with vapor accumulation beneath the paved surface. A vertical ten foot well will be drilled next to the dispenser, 'where laboratory analyses recorded .013 ug/g and .008 ug/g of toulene and ethlybenzene respectively, at five feet below grade. A second vertical fifteen foot well will be drilled in the center of the tank excavation, were the only field screening measurements of 2.4 ppm and 1.6 ppm, at five and eleven feet below grade, were recorded. The wells will be constructed using a PVC completion with perforations from total depth to 1.5 feet below the surface. A ventilation pipe will be installed to ensure maximum dispersion and dilution of contaminant vapors. The ventilation of soil at the dispenser and tank sites will greatly reduce the hazard of vapors accumulating beneath the pavement as a result of contamination associated with the site. Concentrations of contaminates will decrease with time due'to; 1) the removal of the sources of product and 2) natural biodegradation processes which are already active and 3) ventilation to the atmosphere of vapors migrating upward from the plumes The time required for TPH gasoline and BTXE concentrations to be reduced significantly or to non-detectable levels in the soil cannot be known. Pacific Geotechnical Associates, Inc. 7 Highland High 9/5/91 A notice will be posted inside and outside the classrooms and maintenance building informing thc public that gasoline contaminated soil is present beneath the driveway and where information concerning thc contamination can be found. This option is feasible and will cost $5,000 or less to implement. 7.4 Option 3/ Excavation, Disposal and Backfill with Clean Soil Excavation and backfill with clean soil will be used to reduce the concentration levels of TPH as gasoline and BTXE in the soil. The contaminated soil will be transported to a Class III disposal site, and the excavated area will be backfilled with clean soil. The excavation will be backfilled with soil free of contamination, organics and debris, and recompacted to standards' set by existing building, codes. The import material should be non-expansive, granular in nature,and certified as clean prior to use. The surface will be graded and resurfaced to meet the needs of the Maintenance Yard facility. Bioremediation may be used to enhance the further reduction of contamination levels in the soil. In time contamination will be reduced as 'natural dispersion back into the clean soil reduces concentration levels. Roughly 90% of the contamination will be removed by excavation to a depth of twelve feet. The soil will be remediated in this fashion until soil samples fall below action levels for TPH as gasoline and BTXE as determined by the KCEHSD. This option is feasible and will eliminate or significantly reduce contamination levels in the soil at both sites. The costs for implementing this option is estimated at $27,000. If properly executed, concentrations will be reduced below action levels and hazards associated with vapor accumulations will be eliminated or greatly reduced. 7.5 Recommendation ~" Option 1 is recommended as the most cost effective remedial action alternative. Biodegradation is a natUral process which is presently active at the site. The volume of contamination is sufficiently small, that 'ongoing dispersion and Pacific Geotechnical Associates, Inc. Highland High Sc~ 9/5/91 biodegradation will continue to either eliminate the contaminants or reduce the concentrations of contaminants to acceptable levels. Sealing of the lot with asphalt will 'isolate the plume from human activity and retard' water percolation and flushing of the plume. 8.0 CloSing This report is intended for the exclusive use of the Kern School District.

County of Kern 2700 "M" Street, Suite 300 Bakersfield, CA 93301 January 15, 1991 Re: Highland High School Site Characterization Permit #: 090009 Dear Ms. Darling: On October 25, 1990, a site characterization workplan for the above referenced site was submitted to the Environmental Health Services Department for your approval. Your response, dated November 7, 1990, was a series of comments to be addressed before approval (copy attached).

See attached Health and Safety Plan Follow OSHA Comment 2. v Discussion of slant borings which may be needed to determine if contamination has migrated beneath the classrooms adjacent to the former dispenser. Response 2. Vertical borings are an efficient and safe way to determine whether or not contamination has migrated beneath the classroom for the following reasons: a. Vertical borings can indicate the risk of an asymmetric plume with a major component beneath the maintenance shop. ,'The migration of fluids through a porous media is powered by gravity 'and capillary pressure. Unless a contamination plume strikes an impermeable inclined plane, it will go straight down with a small component of horizontal expansion. When encountering an impermeable inclined plane, the plume will "drift" in a down dip direction. At the Highland High School site, the strata are relatively flat. A contamination plume will tend to be radially symmetrical with respect to the vertical axis. Therefore, three or more borings at increased distances from the axis of the plume (under the dispenser) should characterize the shape of the plume. If an impermeable or semipermeable horizon is encountered during the initial borings, the attitude of the bed will be determined in the field, and if the. dip is in the direction of the maintenance shop, a decision can be made at that time to advance a slant boring. b. Unnecessary slant drilling adds an unnecessary safety risk to the project. Truck mounted augers are designed to operate Optimally with the mast in the vertical position. The mast can be tilted to perform slant boring, but unusual stresses are placed both on the equipment and the operators. In addition, boring beneath buildings poses the risk of encountering buried pipes and wiring, footings, and any other unseen objects that may be beneath the structure. For these reasons the following boring program is proposed: The Highland High site borings will be positioned immediately adjacent to the building (see Figure 2), and if an impermeable, or semipermeable horizon is encountered, its depth below grade will be plotted in each boring on a map. The attitude of the bed will be determined using the three-point method, and if necessary a slant boring beneath the maintenance shop will be located in the field by the project geologist with the concurrence of a representative from the Environmental Health Services Department (see paragraph 2.0 of the attached Quality Assurance/Quality Control Procedures).

Sincerely,~ //~ ~ PUora Darling, R.E.H.S. · Hazardous Materials Specialist Hazardous Materials Management Program cc: Pacific Geotechnical Associates \090009.1tr QUALITY ASSURANCE/QUALITY CONTROL PROCEDURES HIGHLAND HIGH SCHOOL BAKERSFIELD, CALIFORNIA 1.0 PURPOSE This study has been undertaken to characterize the soil at an underground fuel tank site at Highland High School (Figure 1). Procedures used in the field will generally follow guidelines contained in the State Department of Water Resources guidance document entitled "L.U.F.T. Field Manual" dated May 24, 1988. The field activities will meet or exceed the requirements of the Kern County Environmental Health Services Department's requirements as outlined in its handbook UT-35. 2.0 BORINGS Exploration will consist, of drilling at least three vertical borings. to a sufficient depth to achieve two consecutive five-foot soil samples showing zero PID reading (above background). The depth of each boring will be determined in the field by the project geologist with the concurrence of a representative from the Environmental Health Services Department. If perched ground water is encountered before the above criterion is met, boring will cease eight, feet below the depth ground water is first encountered. The borings will be positioned immediately adjacent to the maintenance shop (see Figure 2), and'if an impermeable, or semipermeable horizon is encountered, its depth below grade will be plotted in each boring, on a map. The attitude of the bed will be determined using the three-p6int method, ahd if necessary a slant boring beneath the building will be located in the field by the project geologist with the concurrence of a representative from the EnvirOnmental Health Services Department. "1/1'5/91 ~Highland High School The locations of the drill holes (Figure 2) will be determined by measurement from known facilities, and elevations will be estimated from a topographic map. The locations and elevations of the drill holes should be considered accurate only to the degree implied by the method used. Borings will be advanced using, an AMS extendable soil recovery auger with a core sampling head capable of retaining a 2-inch in diameter by 6-inch long brass sampling tube.. The maximum penetration ~e_pth of the hand auger is 'approximately 21 feet. In the event that deeper borings are required to successfully complete the site characterization, a truck mounted, hOllow .stem flight auger will be employed. After drillin~ to the depth reached by the hand auger, a Modified California split-spoon sampler will be used to obtain undisturbed soil samples. The sampler consists of a 3.0-inch outside diameter, 10-inch long, steel sampler which contains up to four, 3-inch long brass sampling sleeves. All drill bits and auger stems will be cleaned prior to the drilling of each hole to prevent cross-contamination. Each boring will be logged by a PGA staff geologist who will also monitor drill cuttings for organic vapor concentrations with a PID with a 10.6 electron volt light source probe. The PID will be calibrated with calibration gas prior to the start, of each day's work. Logs of the drill holes containing information regarding earth materials encountered, depths and elevation of samples obtained, and the results of field testing will be prepared. Log preparation will be supervised by PGA geologists registered by the state of California. 3.0 SAMPLES Prior to the collection of each sample, sampling equipment will be washed the a nonphosphate detergent solution, triple rinsed with distilled water, and air dried. ~'~. Soil samples for analyses will be retrieved at five foot intervals beginning at five feet below grade and at any change in lithology. QA/QC Page 2 1/r5/91 ghland High School Immediately after sampling, sample sleeves will be sealed with Teflon sheets and air-tight caps, taped, labelled, and placed in a cooler containing artificial ice and kept at or below 4°C. Chain-of-Custody forms will be completed when the sample is collected and maintained with each transfer of the sample. If groundwater is encountered, a water sample will be retrieved using a disposable bailer. The fluid sample-will be sealed in a labeled, glass sample jar and stored in an ice chest and kept at or below 4°C. Chain-of- Custody forms will be completed when the sample is collected and maintained with each transfer of the sample. At the end of each day, all samples will be transported to SMC Laboratories, 3155 Pegasus Drive, Bakersfield, California, 93308, a California state Certified Laboratory. Soil samples will be analyzed for TPH and BTXE using EPA methods 3810/8020, and fluid sample~ will be tested using EPA 601- 602 for water.. 4.0 'SPOILS DISPOSAL AND BORING DESTRUCTION All soil not preserved for laboratory analysis will be placed in a 55-gallon drum which will be sealed, labeled, and temporarily stored at the site. All riasate will be placed into the drum along with the drill cuttings.?( When the drum is full a representative sample will be retrieved using a soil sampling device. The sample weighing at least two pounds will be placed in a glass sample jar, leaving no head space. A teflon sheet will be placed over the mouth of the jar, the lid will be firmly secured and sealed with tape. The sample will be sent to Laidlaw Environmental Services, a state registered waste hauler, for analysis. A copy 'of the analysis will be included in the final site characterization report. Upon completion of laboratory analysis, the drum will be transported by Laidlaw to a state approved hazardous waste disposal site. All borings not completed as monitoring wells will be backfilled with cement. Borings advanced using the truck mounted auger will' be abandoned by backfilling with cement sand slurry implaced with a tremie pipe. QA/QC Page 3 1/f5/91 ghland High School 5.0 MONITOR WEI .! ~S Depth to ground water is greater than 350 feet as indicated on Kern County Water Age.ney map "Depth to Water in Wells, Sept. 1989." If contamination is found on ground water, three monitoring wells will be installed. Kern County Environmental Health Services Department will be notified and water well permits will be secured immediately after penetration of the water table. 'The exact construction of the monitoring wells will be subject to 'findings during drilling of the soil borings. The soil borings Will be completed with flush threaded schedule 40 PVC pipe. The completion interval will consist of gravel packed, flush threaded schedule 40 PVC liner with 0.020-inch manufactured slots. A three foot bentonite annular seal will be placed above the slotted liner. Cement grout will be placed around casing from the annular seal to the surface. The completion interval will be 15 feet, half of which will extend below the water table and half above. A 4-inch diameter completion 'will be made if the well is considered to be a potential remediation candidate. Otherwise, a 2-inch well completion will be made. The completion interval in soil boring #2 may be extended to within five feet of the surface to allow for alternative remediation options.

This project will be conducted by Self Insured Schools. of Kern (SISK) and Pacific Geotechnical Associates, Inc. (PGA). 2.0 SITE HISTORY In accordance to the Kern County Environmental Health Services, SISK is 'submitting this Health and Safety Plan to guard worker safety at the site. Soil contamination was documented during removal of an underground fuel tank by McNabb Construction Company. Soil samples taken two feet and six feet below the dispenser recorded 670 and 17,000 parts per million Total Petroleum Hydrocarbons respectively. After the tank was removed the excavation was backfilled with spoils. The excavation was not lined prior to backfilling. The Site Characterization Work Plan to which this Health and Safety Plan applies calls for at least three boring for the purpose of obtaining undisturbed samples for laboratory analysis. The planned list of work is summarized in the following tasks: Task 1: Preparation of a Site Characterization Work Plan and this Health and Safety Plan. Task 2: Drill at least three soil borings to depths sufficient to characterize the contamination plume. Undisturbed soil samples .will be collected at 5-foot intervals. Each boring will be geologically logged and monitored for hydrocarbon vapors with a portable photoionization detector (PID). Soil borings will be destroyed by filling with cement. All drilling spoils and rinsate will be sealed in 55-gallon drums and transported to a certified.. hazardous waste disposal facility. ',. Task 3: The soil samples will be submitted to SMC Laboratories for chemical analysis for TPH and BTXE using EPA method 8020. "1/~5/91 ghland High School Task 4: Prepare and submit a technical report summarizing of the results of the site characterization including, but not limited to results and interpretations of data, discussion of methodologies, boring descriptions and remedial action options including a recommended option and risk appraisal. 3.0 EMERGENCY CONTACTS In the .event of an emergency occurring during the characterization program, the following emergency facilities are available: Police - Call 911 Fire - 911 or 871-7387 Fire Station No. 8 2213 University (south on Tartan PI, east on Auburn, north on Fairfax 1/2 mile, west on Panorama, west on University 1-1/2 miles) Ambulance '- 911 Hospital Kern Medical Center 1830 Flower 326-2000 (west on Hwy 178, south on Mt.

In case an emergency occurs, the following procedUres should be implemented: Minor Cuts or Abrasions, Wash affected area with soap and water and bandage. A first aid kit with eye wash solution must be located on site. The site safety officer is basic first aid trained. Serious Physical Injury. In the event of serious physical injury: a. Call immediately for ambulance or medical assistance. b. Follow protocols established in the Medical Emergency Reference Manual gl (Emergency Medical Planning, Inc.) until assistance arrives. The site safety officer is basic first aid trained. c. If an ambulance is not available, transport victim to nearest hospital (Kern Medical 'Center). H & S Page 2 1/'15/91 OHighland High School The following information must be recorded by the project engineer or site safety officer for any emergency situation as soon as possible: ao Notifier's name. Date, time, and location of the incident. Nature of emergency (describe what happened). Type and amount of materials involved. Extent of injuries, if any. Agencies and/or organizations notified, names of people notified. Actions taken. 4.0 PERSONNEL The following personnel are expected to be at the site during the assessment project: SISK PGA Drilling Operator Kern County (EHS) Rod Williams Randall Metz and/or Brian Hirst (unknown at time of publication) Flora Darling Mr. Rod Williams is designated as site safety officer and will be responsible for ensuring compliance with this plan at all times. Mr. Williams has completed the 8-hour Health & Safety Supervisors Training course. Mssrs. Williams, Metz and Hirst have completed the necessary 40-hour Health & .Safety Training requirements. Drilling personnel will also have the necessary Health & Safety training. Personnel access to the work zone will be limited if Level C personnel protective equipment are required. Only personnel properly equipped with Level C equipment (see Section 10.0 below) will be allowed to enter the contaminated zone. SISK 'will provide Level C equipment for only SISK, PGA and the drillers. 5.0 WASTES The contaminant to be encountered at the site is gasoline. The specific hazardous substances that are likely to be encountered are shown in Appendix A. Applicable exposure data for these substances are presented in Table 1 Hazardous Substances Data. Symptoms of exposure and first aid treatments for each chemical are presented in Table 2 - Exposure Symptoms and First Aid Treatment. As listed in Table 1, the lowest permissible short-term exposure limit (STEL) concentration is 5 ppm (for benzene). This concentration will be used to establish the requirement to don Level C personnel proteftive equipment (see Section 9). ~ Contaminated boring spoils and rinsate will be sealed in "~55-gallon drums, labeled and stored on site pending sample analyses and acceptance by a licensed waste disposal facility. H & S Page 3 1/I5/91 ghland High School 6.0 JOB HAZARDS Chemical hazards could be encountered from direct skin contact with the contaminated 'soils or breathing volatilized chemicals in the air. Level D equipment includes standard work clothing and gloves which would reduce direct skin contact' with chemical encountered (see Section 5.0). A photoionization detector (PID) will be in continuous use in the breathing zone and if organic vapor concentrations of 5 ppm above background are detected, Level C equipment, will be donned by all personnel in the contaminated zone. The respirator should protect workers from-inhaled contaminants. Weather conditions have the potential to disrupt the project in that if it is raining, drilling and sampling should be postponed. It is unlikely that temperature conditions would preclude completion of the project. Temperature ranges expected to be encountered are 50°F to 70°F. 7.0 RISK ASSESSMENT The potential for adverse health or safety risks to the on-site workers or the immediate surrounding area is low. Concentrations of the hazardous substances encountered in the previous assessment at the site have been low, and it is unlikely that high concentrations will be encountered especially considering that the source of contamination, the underground fuel tank, has been removed. Since the site is located outdoors, the atmospheric dispersion of contaminants will be significant. Special arrangements for possible school evacuation should not be required. No authorized personnel may be permitted to stand near the boring location during site characterization. If students, school employees or any other non-essential personnel enter the work site, they will be informed that health and safety procedures have been established to protect both the workers and the public. If they refuse to leave, school administrators will be contacted. 8.0 EXPOSURE MONITORING A PID will be in continuous use during drilling operations. The ionization constants for all of the substances likely to be encountered (benzene 9.24eV, ethylbenzene-8.76eV, toluene-8.2eV and xylene-8.56eV) are all within the detection range of the PID (less than 10.2eV). If the organic vapors in the breathing zone detected by the PID exceed 2 5 ppm above background levels (to be measured prior to excavation and up-wind of the site) for more than five minutes, the personnel in the contaminated zone will don Level C protective equipment, including respirators. Level C equipment will be worn continuously in the contaminated zone until such time as the PID concentrations are below 5 ppm above background. If PID concentrations measured in the breathing zone exceed 1,000 ppm above background, the~-site area will be evacuated immediately. Reent, rY will not be allowed until concentrations are beloTM 1,000 ppm Or Level B equipment is provided. Care will be taken in operating the PID to avoid monitoring vehicle exhaust.

Level D equipment includes: · hard hats · safety boots · eye protection (safety glasses or goggles) · neoprene gloves (while handling samples) If organic vapor concentrations equal or exceed five ppm above background, all personnel in the contamination zone (see Section 10) will don Level C equipment and remain in Level C equiPment until organic vapor concentrations are reduced to below five ppm above background. Level C equipment includes Level D equipment plus: · half-face respirator equipped with combination organic vapor/dust cartridges · tyvek suits SISK will provide Level C personnel protective equipment for its own representatives. If Level C equipment is required, only personnel equipped with Level C equipment will be allowed to enter the contaminated zone, which includes the immediate working area. Anyone other than the SISK representatives and the drillers who desires entry into the exclusion zone under Level C conditions will be required to provide his/her own Level C personnel protective equipment and demonstrate applicable qualifications. The site safety officer or the designated assistant will ensure that no one without proper personnel protective equipment enters the exclusion zone under Level C conditions. Level C equipment provided by SISK will be stored in the SISK vehicle when not in use. 10.0 WORK ZONES Two basic work zones will be established for this project: a restricted zone (exclusion zone) encompassing the drilling area and a clean zone. Only the exclusion zone may be formally delineated by a tape barrier. The decontamination zone and clean zone will be separated by function only. Final zone boundaries will not be delineated. 11.0 DECONTA/vIINATION All personnel who have been working in the contamination zone as defined in Section 10 above shall undergo personal decontamination: · when leaving the exclusion zone for coffee or lunch breaks; · at the end of the work day.

I hope this plan is satisfactory to you and meets the criteria as stated in the "UT-35 Handbook." Should you have any questions as you review this plan, please feel free to call my office at any time for clarification. CONSULTING FIRMS The Self-Insured Schools of Kern (SISK) Safety and Environmental Control Staff has been selected by the Kern Union High School District to act as their Environmental Consultant. SISK will coordinate and develop all plans stated above. SISK will utilize the services and expertise of Pacific Geotechnical Associates, Inc. (PGA), a firm consisting of professional geologists registered by the State of california, to collect soil samples as described in this work plan and to review, approve, and sign all work plans submitted to the county for approval. SITE BACKGROUND The Kern Union High School District has instituted a program to eliminate several underground fuel tanks at various locations within the City of Bakersfield. On April 12, 1990, one (1) 1,000 gallon unleaded gasoline underground storage tank and associated ~dispenser were removed from the southeastern drive area at Highland High SChool (Plate I). Inventory records indicate no loss from the tank prior to removal, but some. staining and Petroleum odor were observed when the dispenser was removed. Soil "SERVING SCHOOL EMPLOYEES THROUGH BETTER RISK MANAGEMENT" Ms. Darling -2- October 25, 1990 samples taken from beneath the tank indicate no contamination, however, samples taken from beneath the dispenser contained contamination levels above acceptable limits, a condition which has prompted this site characterization work. ~epth to groundw is greater than 350 feet as indicated on the Kern County 'Wat~f~A~eTF~"~ap "Depth to Water in Wells,-'September 1989" (attached as Plate II). The topography consists of low hills. PRELIMINARY SITE ASSESSMENT RESULTS A total of four (4) soil samples were collected from beneath the tanks by McNabb Construction Company and analyzed by BC Laboratories, Inc. (laboratory reports are attached). A summary of those analyses is as follows: SAMPLE LOCATION LABORATORY ANALYSIS (TPH) 2 feet under tank ........................ None Detected 6 feet under tank ........................ None Detected 2 feet under dispenser ................... 670 ppm 3 feet under dispenser ................... 17,000 ppm The samples retrieved from beneath the tank exhibit "None Detected" levels of Total Petroleum Hydrocarbons (TPH), however, samples from beneath the dispenser location have values in excess of Department of Health Services (DOSH) recommended action levels for soil. Following the removal of the tank, the excavation was backfilled and covered with clean soil (see figures 1, 2, 3, and 4). SOIL SAMPLING PLAN Introduction The following program is designed to assess the vertical and horizontal extent of contamination in the soil for the underground gasoline tank site. The program consists of a minimum of four (4) soil borings. Additional borings will be considered if contamination is laterally extensive. Locations and Depths Plate III shows the approximate location of the soil borings. These are numbered in the order in which they will be drilled. The following rationale was used for location selection: 1) Soil boring #1 will be made directly under the past location of the dispenser. Its purpose is to define the vertical extent of contamination. 2) Soil boring #2 will be between the dispenser and the center of the former tank location. Soil boring #2 will establish the vertical extent of contamination (if any) below the tank. Soil borings #3 and #4 will be Ms. Darling -3- October 25, 1990 approximately ten (10) and twenty (20) feet, respectively, from the dispenser and at 120 degree angles from one another to cover the largest possible area. The purpose of the three latter-borings is to define the lateral extent of contamination. Boring will cease after two (2) successive soil samples show measured. Volatile Organic Compounds (VOC) concentrations of zero (0) parts per million above background on an Organic Vapor Monitor (OVM). OVM readings will be taken before soil boring begins to establish background values. All VOC concentrations will be documented on a field boring log which will be submitted to the KCEHS as part of the site characterization report. Destruction of Borings and Spoils Management Ail borings will be backfilled with bentonite clay and capped with concrete. Augered soil not preserved for laboratory analyses will be sealed and stored in 55-gallon drums. Laboratory Analysis, 9A/QC Soil samples for laboratory analysis will be collected in brass tubes. After the ends of the sample tubes have been examined for lithology and any visible staining, they will be covered with a Teflon seal and a plastic cap. The cap will be secured with duct tape, and the sample will then be labeled and placed in an ice chest which will maintain the temperature at, or below, 4 degrees centigrade. At the end of the day, all samples will be transported to SMC Laboratories, 3155 Pegasus Drive, Bakersfield, California 93308, a California State Certified Laboratory. Samples will be analyzed for TPH and BTXE using EPA methods 3810/8020. Chain-of-Custody forms will be completed when the sample is collected and maintained with each transfer of the sample. Sampling Equipment and Procedures The initial borings will be advanced using an AMS extendable soil recovery auger with a core sampling head capable of retaining a 2-inch by 6-inch brass sampling tube. Cutting samples will be described and recorded on a continuous log. The shoe of the auger head will be field screened with an OVA for VOC's with each sample retrieved. Soil samples will be taken at five (5) foot intervals commencing at fifteen (15) feet below grade in boring #1 and ten (10) feet below grade in borings ~2, #3, and #4. In the event that contamination extends below the sampling capability of the extendable auger, the soil boring will be advanced with a truck- mounted, hallow-stem auger. The augers will be steam cleaned at the beginning of work and between each soil boring.. Soil samples will be MS. Darling -4- October 25, 1990 retrieved using a split-spoon sampler and brass tubes using the same procedure as described above. Ail sampling equipment and brass tubes will be washed in a non-phosphate detergent and rinsed with distilled water between samples and between each boring. HEALTH AND SAFETY Personnel involved in the site characterization field work will comply with Level D personal protective equipment (boots, hard hats, eye pFotection). This will be augmented by wearing neoprene gloves when handling samples and sampling equipment. Highland High School is located at the site and will be used for communication. and first aid should an accident or emergency occur. The site will be flagged off to control public access, and all personnel and visitors to the site will sign the site log book each day. REPORT OF FINDINGS A summary report will be prepared by SISK ~nd approved by PGA which will document field procedures, sampling procedures, analytical results, and data analysis. This information will then be used to develop the Site Characterization Report and the Remedial Action Options which will be submitted to the county for approval. The Site Characterization Report will conform to KCEHS requirements as outlined in "UT-35." RNW/RTM:vrs Enclosures cc: Janet Shell Sincerely, Rodney N.
