Soil samples, were collected on March 17, and June 2, 1993, and were analyzed to assess the effectiveness of the low temperature diesel oxidation system. Three soil samples were collected at CB-1W, near the western well (VW-1), at 5, 10 and 15 feet below grade. Two samples were collected at CB-2, near the eastern well (VW-2), at 5 and 10 feet (Plate 2). Each sample was analyzed for BTEX and TPH diesel using EPA methods 5030/8015 modified.

These results indicate that the low temperature oxidation system has been successful in remediating the diesel plumes. On July 8, 1993, three groundwater wells were sampled to assess the water quality near the former plume locations (Plate 2). These wells, designated MW-2, MW-3, and MW-6, were purged a minimum of three well volumes before sampling (see attached groundwater monitoring data sheets). Each sample was analyzed for BTEX and TPH diesel using EPA methods 5030/8020/8015. The results of the analysis show that no hydrocarbons were detected in any of the samples collected (Table 1) The results of the soil analysis show that the soil plumes have been completely remediated. In addition, it has been shown that the groundwater in the vicinity of the former plume locations has not been impacted. It is recommended, therefore, that closure of the site be initiated immediately, and the wells MW-2, MW-3, and MW-6 should be abandoned in accordance with State and County regulations. If there are questions we can answer or more information is required, please feel free to call us at 835-7700. Sincerely, - ~.'~l[/I 0~?~,. Timothy C.

As required by the AQMD permit, RESNA has visited the site weekly to monitor the operating conditions and to collect air samples for gas-chromatographic analyses. The purpose of the project is to accelerate in-situ oxidation of diesel contaminated soil by the induction of a draft of air through the soil. Since the source is a relatively small amount of weathered diesel, little or no volatile hydrocarbons were expected to be removed to the surface, and indeed, this has been the case. Our monitoring of the extracted soil gases has not resulted in the detection of any volatile organic compounds either upstream or downstream of the carbon canister, and none are expected in the future. All VOC's should have been purged immediately after start-up of the project. Consequently, we cannot calculate that any hydrocarbons have been or will be extracted. In order to assess the effectiveness of the remediation process, a soil boring will be made into the center of the plume. Soil samples will be collected every five feet. The samples will be sent to a state certified laboratory and analyzed for TPH diesel using EPA Method 418.1. Notification of drilling will be made to your office 48 hours in advance.

RESOURCES, INC. ~.'king u~ Re,¥tore Nature May 10, 1991 'Mr. Thomas Paxson, P. E. Air Pollution Control District 2700 M Street, Suite 275 Bakersfield, California 93301 BAKERSFIELD. CALIFORNIA 93307 General Engineering Contractor Class A/Haz License No. 609572 1991 Golden Empire Transit Request for Exemption to Rule 201 Authority to Construct Dear Mr. Paxson, On behalf of Golden Empire Transit, RESNA/Groundwater Resources Inc. (GRI) appreciates your advice and recommendations in our telephone conversation of May, 8, 1991. We hope that this discussion and the attached supporting data provides the information needed for the evaluation of our request. GRI has been retained by Golden Empire Transit (GET) to provide a workplan to the Kern County Department of Environmental Health Services (KCDEHS) for the remediation of two small plumes of diesel contaminated soil. The workplan has been approved and a copy is attached for your review. On the basis of the very small size of the project and the resulting minute amount of emissions expected, we are requesting an exemption from Rule 201 requiring an application for an authority to construct. The plan Calls for low temperature, low rate in situ oxidation of the non-volatile components of the fuel. Oxidation will be stimulated by the extraction of fresh air through the soil pore volume. Total hydrocarbons in place are approximately 590 pounds; however, only about 7.5 pounds axe volatile as BTXE and might be extracted to the surface. Granular activated carbon will be used to capture these volatiles in the fn'st weeks of the project. Thereafter, VOC's are expected to decline to less than detectable levels. 1.0 BACKGROUND (Site Characterization) 1.1 Plume Dimensions The site characterization report to the KCDEHS included a description of the extent of the contamination. There are two plumes, one located under each diesel fuel dispenser. Please refer to the attached cross-sections. The plumes are on the order of 12 feet in diameter at the limits of detection for TPH (diesel). Thc site is in usc as thc fueling depot for GET. There is a re-enforced concrete slab on grade, and an overhead canopy. The water table is shallow and varies seasonally from 18 feet to about 26 feet below grade. The soil type is well sorted medium to coarse grained sand which will allow for an effective sweep of air through the plume. MAILING ADDRESS: P. O. BOX 9383, BAKERSFIELD. ca 93389 (805) 835-7700 FAX (805) 835-7717 lVir. Thomas Paxson, Air Pollution Control May 10, 1991 Page Two -1.2 Soil Sample Results Soil samples collected from the plume show maximum TPH (diesel) concentrations of 18700 ppm in the soil, and maximum benzene levels of 1.45 ppm. The same sample produced the highest total BTXE concentration of 37.13 ppm. The maximum values are used with the largest expected plume volume to provide a worst case estimate of the total mass of benzene and BTXE in place. TPH(d) totals are calculated from the cross sections. The volumes of soil between, the contours are factored with their respective average contaminant concentration to produce a TPH mass between contours. These are then totaled (see the attached "spreadsheet"). 2.0 PROPOSED WORK Please see the. Workplan attached for the following details: - Location - Plot Plan - Process Diagram 3.0 HYDROCARBONS IN PLACE (Calculations Attached) 3.1 Total Petroleum Hydrocarbons The total hydrocarbons in place as TPH (diesel) are calculated to be 1172 pounds, contained in a volume of about 67 yards of soil. 3.2 Benzene The worst case estimate for total benzene in place is .3 pounds. 3.3 VOC's as BTXE Total VOC's are the sum of the components found in the most severely contaminated soil test. This value produces a total BTXE mass of 7.46 pounds. 4.0 CARBON LOADING AND RESULTANT EMISSIONS A single canister of granular activated carbon is planned for the adsorption of the 7.46 pounds of VOC's. Attached is a technical data sheet and an isotherm diagram plot for BTXE. The 7.46 pounds of VOC's will load into the 170 pounds of carbon at a loading factor of .044 pounds of VOC to 1 pound of carbon. At this loading level, the isotherm chart indicates that the outlet concentrations of the VOC's will rise to a maximum of about 2.3 ppm v/v. At the point at which all of the VOC's are extracted from the soil, the carbon influent will be decreasing as the source is depleted. That is, the 2.3 ppm emission level is a short term peak. ' A VOC emission rate of 2.3 ppm v/v at the planned 30 scfm will produce a maximum emission rate of .019 pounds per day. The corresponding rate for benzene is 7.4E-4 pounds per day. The influent and the effluent will be monitored at start-up, the next day, and then weekly as needed to assure that carbon emissions do not exceed the expected amount. If they do, the carbon will be replaced. Mr. Thomas Paxson, Air Pollution Control DistriCt May 10, 1991 Page Three 5.0 PROJECT DURATION The project duration may be as great as two years; data is not available on this method. Soil borings and samples will be needed to document completion. Influent of volatiles into the carb°n canister should decline to non-detectable levels as the limited source is depleted. This is likely to occur within the first three to four weeks of operation, after which no further detectable emissions from the carbon outlet should. occur.. We hope that this information is sufficient to allow a favorable decision upon our request for an Authority to Construct exemption on this project. If more data is required or there are questions we can answer, please fccl free to call us at (805) 835-7700.

Department of Environmental Servaccs 2700 "M" Street, Suite 300 Bakersfield, Ca. 93301 Golden Empir~ Transit 1830 Golden State Avenue Permit//060013 Remedial Action Plan Fuel Dispensers Dear Ms. Gough, On October 12,. 1990, RESNA/GroUndwater Resources, Inc., on behalf of Golden Empire Transit, provided a Remedial Action Plan for thc remediafion of two small diesel plumes under thc dispensers at Golden Empire Transit, 1830 Golden State Avenue. That plan called for thc excavation and bio- remediation of thc plume on the surface, Duc to cost of bids on the constroction work exceeding $90000 for shoring of the excavations and for alteration of the canopy over the site, we have re-evaluated the options for remediation techniques. We now propose to rcmediatc the site by "vapor extraction". Since thc contaminant is diesel fuel thc actual mechanism for remcdiarlon will be in-situ low temperature chemical and biological oxidation. In thc original Site Characterization dated August 10, 1990, vapor extraction was briefly discussed and diseoumed because of the uncertainties (at that time) of this method for treatment of diesel contamination. On March 20, 1991, Gary Cawthon of GRI spoke with you on the telephone about thc suitability of vapor extraction and based upon recent positive results GRI received encouragement to propose this method and to submit a revised Remedial Platt of Action for your approval Such a remedial action plan is enclosed. 1.0 Results of Final Field Studies .and Laboratory Analyses The field studies and lab analyses were covered in detail in the Site Characterization Re,on dated August 10, 1990. Please refer to that repOrt for tabulated lab results, plume cross sections, soil boring logs and lab results. Soil samples taken by hand auger from beneath the fuel dispensers and thc related piping on October 10, 1989, indicated that no sell contamination occurred in relation to the piping, but some contamination was found beneath tho dispensers. The east dispenser showed 12000 ppm TPH (diesel) at 3 feet and 1400 ppm at 7 feet below grade (2 and 6 feet below the adjacent piping). The west dispenser produced revers of 16700 and 18700 ppm respectively for TPH (diesel). MAILING ADDRESS: P. O. BOX 9383, BAKERSFIELD, CA 93389 (805} 835-7700 FAX (805) 835-7717 Ms. Dolores Gough County of Kern Department of Environmental Sec'vices April 1, 1991 Page Two. Subsequent soil borings drilled on Sune 20 for the site assessment found no contamination below a depth of 10 feet. Boring B-S, at the west dispenser, did show a 16 ppm result for TPH (d) at 10 feet and less than 14 ppb xylene. All other soil boring analyses showed no detectable hydrocarbons. On the basis of the above work, (]RI defined the contamination as lying in two distinct plumes, one under each dispenser. The vertical extents ar~ less than 15 feet and the diameters are apparently less than 12 feet. 1.1 Total Hydrocarbons in Place; Worst Case Based upon the highest concentrations of diesel TPH and benzene found at this site and a greatest estimate of thc volume of soil affected, we have calculated a maximum amount of diesel as TPH to be 1222 lbs. The greatest possible benzene amount is .328 lbs. or $ oz. · 2.0 Method of Remediation The method of rcmediation is to be in-sim low temperature oxidation (weathering) by inducing a flow of atmospheric oxygen'through the plume from venting wells placed in the center of each plume (see thc attached process diagram, plate 3). .. 3.0 Remediation Activity Details One 2 inch diameter PVC cased well will be placed in thc center of each of thc two plumes. Thc wells will be slotted from 15 feet to 5 feet, and blank pipe will be scaled to thc surface. These wells will be plumbed to a single drum of granular activated carbon which will remove from thc discharged air any volatile hydrocarbons. Thc total VOC load is expected to be only a small fraction of the carbon drum's capacity. The air will be extracted with a small regenerative blower powered by a 1/3 lip explosion proof motor. Air flow rates will be approximately 30 cfm which will provide about 75 pore volume exchanges of fresh air per day in thc soil plume. The blower will be placed downstream of thc carbon to prevent compressive heat exchange to the carbon and to prevent uncontrolled VOC release due to system leakages. It is expected that an APCD permit' will be required for operation of this system. If so, a delay in start up of as much as six months may occur during processing of the application. 4.0 Expected Concentrations After Remediation The expected level ofTPH (dicscl) at completion of thc project will be less than 100 ppm. Since this site is in coarse clean river sand,'adsorption of benzene to clays will probably not be a problem. Reduction of benzene to less than.1 ppm should be achievable. Ms. Dolores Gou§h County of Kern. Department of Environmental Services April 1, 1991 Pa§¢*llucc 5.0 Sampling and Analysis Plan The APCD will iv. quire mOnitoring of thc volatile organic hydrocarbon concentrations and air flow rates at thc carbon inlet and outlet at thc start up and periodically during thc operation of thc system. In view of thc very small total mass of volatilcs and small dimensions of thc plumes, VOCs arc cxpec~.d to bc below detectable levels within thc first couple of days of start up. In order to monitor the progress of thc plume rcmcdiation, samplcs of thc affected soil will have to bc taken periodically. Samples from each plume have been collected and analyzed from a depth of seven fcct (where thc hi§hcst previous hydrocarbon levels were found). A second set should be taken at three months to provide a means to estimate the total time to completion. 6.0 Health and Safety Plan Since thc hydrocarbon source is diesel fuel and thc working mca is in open air, high levels of volatile organic compounds arcnet expected. All workers will bc equipped with respirators fitted with organic chemical cartridges, and a SCBA apparatus will bc on hand. VOCs will bc monitored with a portable PID mctcr. All workers will wear hard hats and steel-toed boots, and each vehicle will have a fire extinguisher. Thc full health and safety plan is attached. 7.0 Implementation of the Plan A major uncertainty.in thc timing of the project is thc processing time for an authority to construct permit from the APCD. This may take as much as six months. The second major unknown in the project duration is the rate of weathering which will occur, but data is lacking on this. For thc purposes of scheduling, we will estimate a one year project life. 8.0 Project' Schedule Date Begin Phase Duration 4/10/91 Submit Remedial Action Plan 1 Wcck Plan Review by County Confirm need for APCD permit Send workplan out tO bid Begin Authority to Construct permit process, Submit application Wait on APCD response Begin conslruction Start up job First test samples on soil Estimate project duration 4/17/91 2 weeks 5/1/91 1 week :518/91 6 mos.? 12/9/91 2 weeks 12/23/91 3 months 3/31/92 2 weeks Ms. Dolores Gough County of Kern Department of Environmental Services April 1, 1991 Page Four 9.0 Contractors Though this work plan is developed for Golden Empire Transit by RESNA/Groundwater Resources, Inc., thc conu'nctor to perform the work is not yet selected.

That plan called for the excavation and bio- remediation of the plume on the surface. Due to cost of bids on the construction work exceeding $90000 for shoring of the excavations and for alteration of the canopy over the site, we have re-evaluated the options for remediation techniques. We now propose to remediate the site by "vapor extraction". Since the contaminant is diesel fuel the actual mechanism for remediation will be in-situ low temperature chemical and biological oxidation. In the original Site Characterization dated August 10, 1990, vapor extraction was briefly discussed and discounted because of the uncertainties (at that time) of this method for treatment of diesel contamination. On March 20, 1991, Gary Cawthon of GPa spoke with you on the telephone about the suitability of vapor extraction and based upon recent positive results GPa received encouragement to propose this method and to submit a revised Remedial Plan of Action for your approval. Such a remedial action plan is enclosed. 1.0 Results of Final Field Studies and Laboratory Analyses The field studies and lab analyses were covered in detail in the Site Characterization Report dated August 10, 1990. Please refer to that report for tabulated lab results, plume cross sections, soil boring logs and lab results. Soil samples taken by hand auger from beneath the fuel dispensers and the related piping on October 10, 1989, indicated that no soil contamination occun'ed in relation to the piping, but some contamination was found beneath the dispensers. The east dispenser showed 12000 ppm TPH (diesel) at 3 feet and 1400 ppm at 7 feet below grade (2 and 6 feet below the adjacent piping). The west dispenser produced levels of 16700 and 18700 ppm respectively for TPH (diesel). MAILING ADDRESS: P. O. BOX 9383, BAKERSFIELD, CA 93389 (805) 835-7700 FAX (805) 835-7717 Ms. Dolores Gough County of Kern Department of Environmental Services April 1, 1991 Page Two Subsequent soil borings drilled on June 20 for the site assessment found no contaminatiOn below a depth of 10 feet. Boring B-3, at the west dispenser, did show a 16 ppm result for TPH (d) at 10 feet and less than 14 ppb xylene. All other soil boring analyses showed no detectable hydrocarbons. On the basis of the above work, GRI defined the contamination as lying in two distinct plumes, one under each dispenser. The vertical extents are less than 15 feet and the diameters are apparently less than 12 feet. 1.1 Total Hydrocarbons in Place; Worst Case Based upon the highest concentrations of diesel TPH and benzene found at this site and a greatest estimate of the volume of soil affected, we have calculated a maximum amount of diesel as TPH to be 1222 lbs. The greatest possible benzene amount is .328 lbs. or 5 oz. 2.0 Method of Remediation The method of remediation is to be in-sito low temperature oxidation (weathering) by inducing a flow of atmospheric oxygen through the plume from venting wells placed in the center of each plume (see the attached process diagram, plate 3). 3.0 Remediation Activity Details One 2 inch diameter PVC cased well will be placed in the center of each of the two plumes. The wells will be slotted from 15 feet to 5 feet, and blank pipe will be sealed to the surface. These wells will be plumbed to a single drum of granular activated carbon which will remove from the discharged air any volatile hydrocarbons. The total VOC load is expected to be only a small fraction of the carbon drum's capacity. The air will be extracted with a small regenerative blower powered by a 1/3 HP explosion proof motor. Air flow rates will be approximately 30 cfm which will provide about 75 pore volume exchanges of fresh air per day in the soil plume. The blower will be placed downstream of the carbon to prevent compressive heat exchange to the carbon and to prevent uncontrolled VOC release due to system leakages. It is expected that an APCD permit will be required for operation of this system. If so, a delay in start up of as much as six months may occur during processing of the application. 4.0 Expected Concentrations After Remediation The expected level of TPH (diesel) at completion of the project will be less than 100 ppm. Since this site is in coarse clean river sand, adsorption of benzene' to clays will probably not be a problem. Reduction of benzene to less than. 1 ppm should be achievable. Ms. Dolores Gough County of Kern Department of Environmental Services April 1, 1991 Page Three 5.0 Sampling and Analysis Plan The APCD will require monitoring of the volatile organic hydrocarbon concentrations and air flow rates at the carbon inlet and outlet at the start up and periodically during the operation of the system. In view of. the very small total mass of volafiles and small dimensions of the plumes, VOC's are expected to be below detectable levels within the first couple of days of start up. In order to monitor the progress of the plume remediafion, samples of the affected soil will have to be taken periodically. Samples from each plume have been collected and analyzed from a depth of seven feet (where the highest previous hydrocarbon levels were found). A second set should be taken at three months to provide a means to estimate the total time to completion. 6.0 Health and Safety Plan Since the hydrocarbon source is diesel fuel and the working area is in open air, high levels of volatile organic compounds are not expected. All workers will be equipped with respirators fitted with organic chemical cartridges, and a SCBA apparatus will be on hand. VOC's will be monitored with a portable PID meter. All workers will wear hard hats and steel-toed boots, and each vehicle will have a fu'e extinguisher. The full health and safety plan is attached. 7.0 Implementation of the Plan A major uncertainty in the timing of the project is the processing time for an authority to construct permit from the APCD. This may take as much as six months. The second major unknown in the project duration is the rate of weathering which will occur, but data is lacking on this. For the purposes of scheduling, we will estimate a one year project life. 8.0 Project Schedule Date Begin Phase Duration 4/10/91 Submit Remedial Action Plan 1 Week Plan Review by County Confirm need for APCD permit Send workplan~out to bid Begin Authority to Construct permit process, Submit application Walt on Al'CD response Begin construction Start up job First test samples on soil Estimate project duration 4/17/91 2 weeks 5/1/91 1 week 5/8/91 6 mos.? 12/9/91 2 weeks 12/23/91 3 months 3/31/92 2 weeks Ms. Dolores Gough County of Kern Department of Environmental Services April 1, 1991 Page Four 9.0 Contractors Though this work plan is developed for Golden Empire Transit by RESNA/Groundwater Resources, Inc., the contractor to perform the work is not yet selected.

The facility is located at 1830 Go]den State Avenue in Bakersfield. Following your approval of that report on September 11, 1990, GRI submits this Remedial Action Plan under the County guidelines published in UT35. The project objective is to eliminate the potential threat of contamination to the shallow groundwater and to reduce the hydrocarbon level of the excavated soil to the extent that it can be used on the property or hauled as clean fill dirt. I Results of Final Field Studies and Laboratory Analyses The field studies and lab analyses were covered in detail in the Site Assessment Report dated August 10, 1990. The analytical results are repeated in the attached Table 1. Soil samples taken by hand auger from beneath the fuel dispensers and the related piping on October 10, 1989, indicated that no soil contamination occurred in relation to the piping, but some contamination was found beneath the dispensers. /he east dispenser showed 12000 ppm TPH (diesel) at 3 feet and 1400 ppm at 7 feet below grade (2 and 6 feet below the adjacent piping).

BOX 9383, BAKERSFIELD, CA 93389 LOS ANGELES (213) 724-3147 (805) 835-7700 Ms. Dolores Gpu County of Kern Resources Hanagement Agency October 12, 1990 Page Two Subsequent soil borings drilled on June 20 for the site assessment found no contamination below a depth of 10 feet. The west dispenser did show a 16 ppm result for TPH (d) at 10 feet and less than 14 ppb xylene. All other soil boring analyses showed no detectable hydrocarbons. See the attached plot plan, Plate 1. On the basis of the above work, GRI defined the contamination as lying in two distinct p]umes, one under each dispenser. The vertical extents are ]ess than 15 feet and the diameters are apparently ]ess than 12 feet. II Method of Remediation The method recommended in the Site Assessment Report and approved by your office is to excavate the plumes and remove the contaminated soil to the surface for treatment (this approach was dictated by the proximity and risk to the shallow groundwater). The selected method of treatment on the surface is bioremediation, based upon our present information. A Excavation In order to minimize disruption of the fueling facility, one dispenser location will be treated at a time. The concrete pad is approximately 8 inches thick and is steel re-inforced. After removal of the dispenser, the concrete will be cut in a circle about 12 feet in diameter and the contaminated soil will be excavated using an extended reach back-hoe. The pad will serve to stabilize the working area for the back-hoe. Screening of contaminated soil from clean soil will be done by a GRI geologist on the location using a portable VOC meter (PIP or FID type). For confirmation of the level of clean-uo, sidewall and bottom samples will be collected and analyzed by a state certified lab for TPH (diesel). Brass tubes driven by an extended slide hammer will be used to gather undisturbed soil samples, The excavation will be back-filled with clean imported soil and compacted in preparation for repair of the pad. The canopy over the fueling facility has vertical support columns near both dispensers. In order to excavate the soil these columns wi]] have to be removed and temporary supports provided. The engineering for this problem is under way now (10/10/90). ~ 8 Remediation of the Soil Up to 100 cubic yards of soil containing diesel fuel at a maximum of 19000 ppm will have to be treated. It is expected that aeration alone will not be fully effective in reducing the non- volatile component of the fuel to acceptable levels. Bioremediation wi]] be used to assist the process. GRI plans to encapsulate the contaminated soil in visQuene in a pile up to 26 Ms. Dolores Got County of Kern Resources Management Agency October 12, 1990 Page Three feet square and four feet thick, Oxygen will be provided by pumping air through a manifold system at a rate amounting to 3 fresh air exchanges per day (2 cfm). The preferred method of supplying air will be to tap into the compressed air system'at the repair shop. A 1 inch dia, galvanized steel pipe would be plumbed from the shop to the soil pile and a regulator and flow meter would be installed at the downstream end. The air distribution manifold will be 1 inch PVC on the main trunk reduced to 1/2 inch perforated PVC beneath the soil pile. Refer to the schematic (Plate 2). The location of the system will be chosen to prevent rain runnoff from saturating the pile or from washing through the pile and carrying hydrocarbons away from the treatment area. A berm of clean soil will be built on the asphalt to contain fluids, and visquene will be laid down over the berm and asphalt. The manifold system will then be set in place and the soil piled on top. Finally, the pile will be covered with visquene which has been perforated to permit air to flow through the top of the soil pile. At start up, the soil will be inoculated with a commercially available culture of soil bacteria selected for hydrocarbon degradation. Water content of the soil and nitrogen and phosphorus levels will be adjusted as needed, To assure proper operation the project will be monitored for moisture content and air flow by a geologist once per week for two to three weeks and thereafter at a reduced frequency. III Remediation Activity Details In regard to remediation rates, a nearly identical project now under way.is producing a half-life for TPH (diesel) of two weeks. Using the worst case assumption for this project that the highest contamination level found (18700 ppm) applies to all of the soil removed, a maximum period of four months is projected to achieve a TPH (diesel) level of less than 100 ppm. It is very likely that due to the necessary mixing of the soil at start up for inoculation and fertilization, the maximum TPH level will be substantially less than 18700 ppm. This will result in a much reduced time to project completion. IV Expected Concentrations After Remediation The expected level of TPH (diesel) at completion of the project will be less than 100 ppm. Depending upon the c].~y3ontent of the soil, benzene will be reduced from the present?1.45.~ppm (maximum) to less than 1 ppm (benzene may persist at det6C~able levels due to clay adsorption or biological activity) /~.~j~ ~,.r.~, -?~'. Hs. Dolores Gout County of Kern Resources Hanagement Agency October 12, 1990 Page Four V Sampling and Analysis Plan During excavation of the soil, four sidewall samples and one sample from the bottom of the hole will be collected. These will be analyzed for BTXE and TPH (diesel) at State Certified SMCj Laboratory. The State DOHS LUFT Hanual test method will be used. ,/The excavated soil will also be analyzed to document hydrocarbon levels at project startup. Four discreet samples 50 cubic yards wilt be analyzed as above (about 8 samples expected). At intervals of one month, four samples per 50 yard unit will ,/collected and composited by the laboratory. These will be used track the progress of the project. When the monthly results indicate that acceptable levels have been achieved, samples will be collected for closure purposes, As in the start up series, four discreet samples per 50 yard unit willl be analyzed and the results included in a Remedial Action Report.~ VI Health and Safety Plan Since the hydrocarbon source is diesel fuel and the working area is in open air, high levels of volatile organic compounds are not expected. All workers will be equipped with respirators fitted with organic chemical cartridges, and a SCBA apparatus will be on hand. VOC's will be monitored with a portable PIP meter. All workers will wear hard hats and steel-toed boots, and each vehicle will have a fire extinguisher. The full health and safety plan is attached. VII Implementation of the Plan There are two major uncertainties in the timing of the plan. The first is due to the needed alteration of the canopy supports. Golden Empire Transit has estimated that engineering, bidding, and bid evaluation on this work will take about eight weeks. The second major unknown in the project timing is the bioremediation phase. The time to completion is dependent upon the initial TPH concentrations, average temperatures within the soil pile and upon the air flow rates. For scheduling purposes, we will estimate that this phase will take 16 weeks to completion.

BOX 9383, BAKERSFIELD, CA 93389 LOS ANGELES 12 ! 3) 724-3 ! 47 (805) 835-7700 SAMPLING PROTOCOL TEST BORING PROCEDURES I. Soil Sampling Protocol The following procedures are following during soil sampling operations utilizing the hollow stem auger drilling technique. A. Hollow Stem Auger Soil borings drilled by the hollow stem auger utilize continuous flight hollow stem augers. Augers, samplers and all downhole equipment are steam cleaned prior to use. In the field steam cleaning is done between borings to minimize the potential for cross-contamination. A G.R.I. geologist observes the work, visually logs the soils, and collects samples at appropriate intervals. The Unified Soils Classification System is utilized to classify soils encountered. Additional geological observations are noted as appropriate. Soil samples destined for laboratory analysis are collected by a modified California Split Spoon. This sampler uses flare,, six inch long, by two and one-half inch diameter (o.d.) tubes. Various tubes can be utilized to accommodate the type of analysis necessary: Brass All organics and general analyses (not to be used for copper or zinc analysis) Stainless Steel All organics and metals analyses for Steel copper and zinc (not to be used for chrome or nickel analyses) Plastic All metals analyses (not to be used for organics) The tubes are cleaned and prepared in the G.R.I. laboratory. Tubes are scrubbed, inside and outside, with a brush and TSP, rinsed, dry.d, and .packed in clean containers with seals. Tubes are delivered to the drilling site an these closed containers to preserve the state of cleanliness. After the sample(s) have been removed from the sampler, the sampler is completely disassembled and scrubbed in TSP and tap water. It is then rinsed in clean tapwater and reassembled with three clean tubes. 8. Dirty tubes are field washed in TSP solution, rinsed with water, and reused. The sampler is driven by a 140 pound hammer with a 30 inch free fall. Blow counts are recorded as number of blows per inch of drive. 10. The sampler is driven 18 inches at each sampling interval. The first (or low, s0 tube is generally retained as the sample for analysis. The other two tubes are retained for back-up or split samples. PAGE 1 GROUNDWATER RESOURCES, INC. SAMPLING PROTOCOL TEST BORING PROCEDURES (continued) 11. 12. 13. 14. A sand catcher is used in thc samplcr where loose softs arc anticipatcd. This will prevent thc soft from falling out of the sampler. After retrieval, the sample is visually logged and immediately sealed with aluminum foil lined caps, labeled, and chilled. Clean ice chests and chemical ice ("blue ice") are used to keep the samples cold until delivered to the chemical laboratory. Teflon seals are also available for field samples. Samples are delivered to thc laboratory thc same day they are taken, if physically possible. If the samples must be held until thc next day, they are kept chilled in a secure location at thc G.R.L facility. Sample control is maintained by a Chain of Custody form which accompanies the sample. The form documents the time, date, and responsible person during each step in the transportation process. MONITORING WELL SAMPLING PROTOCOL Groundwater Sampling All equipment that is used in a monitoring well for purging, sampling, or depth measurement is decontaminated by steam cleaning or a TSP wash and rinse procedure prior to use and before re-using when more than one sample is collected. B. Purge Volume Determination The following procedure is followed to determine the appropriate purging volume prior to well sampling. 1. The depth-to-water is measured by a clean, electric level indicator. Measurement datum is the top of well protector. Depth to thc bottom of thc well is measured by a clean tape and plumb bob. If possible, this is compared to the well construction log to determine inconsistencies, i.e. damaged casing, sediment in casing, etc. Water volume is calculated by using the total water depth and the inside diameter of the casing. C. Well Purging and S_a_mpling Prior to sampling, a minimum of three to five well volumes are purged from each well to ensure that water sampled is representative of the groundwater within the formation. Measurements of oH, conductivity and temperature are taken at frequent intervals during trio purge. Stabilization of these values indicates that representative formation fluids arc being removed from thc well. PAGE 2 - GROUNDWATER RESOURCES, INC. SAMPLING PROTOCOL MONITORING WELL SAMPLING PROTOCOL (continued) e In the event that the well is pumped dry, and alternate procedure will be followed. Once a well is pumped dry, the water that enters the well during recovery is, by definition, representative formation water. The well will, therefore, be pumped dry and allowed to recover to 80% or more of the original water level. Purge water is pumped directly into barrels on site until the proper method of disposal is determine& Samples are pumped or poured from a bailer into sampling bottles prepared by a state certified laboratory contracted for the particular job and placed in refrigerated coolers for transport to the laboratory. Samples are delivered by courier, directly to the lab on the same day of sampling, whenever practical. If next day delivery is necessary, the samples are kept refrigerated at 4 degrees C overnight and delivered to the laboratory the following morning. Samples are accompanied by a Chain of Custody form which documents the time, date and responsible person during each step of the transportation process. The G.R.I. coded sample numbering system allows identification of sample and client to G.R.I., while not revealing the client to anyone else. PAGE 3 GROUNDWATER RESOURCES, INC. RANDALL L.

(GRI) for the subject site. The report indicated the presence of gasoline and diesel contamination beneath both dispensers. The extent of each plume was estimated to be 15 feet deep with a lateral diameter of 10-12 feet. The groundwater depth was measured to be 25 feet. The laboratory results indicated that the water has not been impacted. However, with this depth, the potential for impacting the groundwater exists. Therefore, remediation of the inpacted soil is necessary. GRI recommended excavating the contaminated soil under each dispenser separately to minimize disruption of normal operations. This Department approved of GRI's recommendation. Prior to ~6~initiating the remediation, we require that the following be addressed: The disposition of the contaminated soil. effective for the diesel contamination. Aeration may not be 2. Clean-up levels. 3. Site health and safety considerations during the remediation activities. 4. Schedule of remediation activities.

In response to a letter from you dated March 8, 1990 requesting clarification in two areas, specifically, the site history and monitoring well permits, we hope that this revision adequately addresses any deficiencies. SITE HISTORY In July of 1987, GRI conducted a line test on the unleaded gasoline pipeline associated with the underground fuel tanks at the GET facility. Approximately three to five gallons of unleaded fuel had been spilled into the backfill near a leak detector adjacent to the tanks. On August 20 and 21, 1987 two monitoring wells were installed as part of the site characterization work. These are shown on the plot plan (Plate 2) as MW-1 and MW-2. Benzene contanfination at MW-1 was found to be sufficiently high (9.36 PPB) that additional characterization was required. No detectabl~ hydrocarbons were found in either the soil or the groundwater at the MW-2 location near the gasoline dispenser. In Septe~nber of 1987 MW-3-87 was installed down gradient from the spill and sampled. No detectable hydrocarbons were found in either the soil or the groundwater. MW-2 was again sampled at this time and again, all results were none detected. Remov'al of the vadose plume was attempted by excavation on November 2, 1987; however, by this time the plume had essentially dissipated. The small volume of fuel lost into the dry pea gravel backf'fll had apparently volatilized. Water samples from MW-1 also showed hy&'ocarbon concentra0~as_b_elaw__a~fi_on levels. In continuing work on the location, GRI removed a new motor oil tank from the location marked on the plot plan near the fueling canopy on September 12, 1989. Results were reported in a letter to your department dated October~4, 1989. In October, GRI was subcontracted to collect samples from beneath the three fuel tanks to the northwest of the fueling canopy, from beneath the diesel fuel dispensers, and from under the associated piping. These results were reported on December 6, 1989. In these two projects, all sub-tank samples and all sub-pipeline samples showed no MAILING ADDRESS: P.O. BOX 9383, BAKERSFIELD, CA 93389 LOS ANGELES (213) 724-3147 (805~ 835-7700 Ms. Janis Lehman Dep _arm~_nt of Environmental Health Services March 23, 1990 Page Two detection of hydrocarbons. In the December 6 report, however, lab results for the two diesel fuel dispensers did show high levels of TPH (diesel) as discussed in the following section. In the preliminary site assessment of the Golden Empire Transit fueling area, contamination of soil was found at depths of two feet and six feet beneath the fuel dispensers. The table below summarizes the results. East Dispenser Benzene TPH (diesel) West Dispenser Benzene TPH (diesel) Depth: 2 feet .11 12000 .77 16700 6 feet ND 1400 1.45 18700 (all values in PPM) PROPOSED BORINGS AND MONITORING WELL GRI proposes to drill four soil borings, labeled on the plot plan as B-3, B-4, B-5 and MW-6. Borings B-3 and B-4 will be as close as possible to the sources and will be drilled to a depth of 16 feet to fred the vertical extent of the plume. Drilling to groundwater will be avoided unless contamination is found to penetrate to groundwater, except in the case of ]~6' to be completed as a monitoring well. Previous drilling at this site has shown that groundwater is at 18 feet, plus or minus one foot. The soil type is medium to coarse fiver sand with a very low silt or clay content. Bedded or lenticular clays have not been observed. Due to this soil texture, any hydrocarbon contamination should be expected to travel vertically in a narrow plume. Vertical extent borings will be as close as possible to the suspected source and lateral borings will be only about six feet from the source. Boring B-5 will be drilled about six feet to the southwest of the west pump location to provide information on the lateral extent of the plume from that source, and boring MW-6 will be drilled about six feet to the southeast of the east pump location. Due to the shallow groundwater at this location and the 18700 PPM TPH value in the soil at six feet, we plan to complete MW-6 as a monitoring well. GRI will have filed with your office at least ten days before work begins, an application and fee for a permit to build a monitoring well. The proximity of the existing well MW-2 was considered in these plans. Due to the fact that no hydrocarbons have been detected in this well in the past and that it is not in a down gradient position to intercept contaminants from the diesel fuel dispensers, GRI felt that this well would provide limited information in assessing the diesel dispenser plumes. We will sample MW-2 again prior to field activities and submit the data before field work begins. PROCEDURES Because of the overhead canopy it will be necessary to use a small skid-mounted fig with a six- inch hollow stem auger. The borings will be screened for indications of soil contamination with an HNU photoionization meter. All cuttings will be drummed in DOT-17H drums and stored on location pending the results of lab analysis of samples. Samples will be collected at five feet, ten feet and 16 feet using a California Modified Split Spoon Sampler. The samples will be sealed in their brass collection sleeves, chilled and transported under a chain of custody document to SMC Laboratory. All samples will be analyzed for Benzene, Toluene, Xylene, and Ethylbenzene and Ms. Janis Lehman Department of Environmental Health Services March 23, 1990 Page Three Total Petroleum Hydrocarbons as diesel (TPH). The borings will be sealed with a bentonite/cement slurry. Two inch diameter PVC will be used to build the monitoring well. As found in previous well installations here, the coarse unconsolidated sand below the water table will require that pipe be set inside the auger stem. The six-inch auger precludes four-inch PVC. Filter pack sand will be needed only from the water table to a point two feet above the top of the perforations. A two foot bentonite seal will cover the filter pack sand and the remainder of the annulus to three feet below ground level. The well will be finished with a locking cap and a traffic box set in concrete. Upon completion, the well will be developed and purged of at least four wellbore volumes. After stabilizing, the well will be measured for depth to water and sampled for BTXE and TPH (diesel). Water produced while developing the well and while purging prior to sampling will be drummed and labeled hazardous material until laboratory analysis results are received. If necessary, the drummed water will be disposed of at Gibson Refinery and the supporting documents will be sent for your files. HEALTH AND SAFETY Since the preliminary site assessment showed benzene levels to be not more than 2 ppm in the soil and soil sampling during the construction of Monitoring Well 2 resulted in no detection of any gasoline constituents, high levels of hydrocarbon vapors are not expected. The site is not enclosed, but concentrations will be monitored anyway to assure that airborne hydrocarbons do not exceed 10 ppm. During the drilling operations, the personnel on site will have on location a Draeger PA-80 Air Pack, respirators with organic chemical cartridges, Gastech D-11 Vaportester or equivalent, fire extinguishers and additional health and safety equipment. A tail-gate safety meeting will be held before beginning work to verify steel-toed boots and hard hats, specific auger- rig safety features, and note hospital locations and emergency phone numbers. All work will be supervised by Rex J. Young (State Registration #720). If you have any additional questions or comments, please contact me at (805) 835-7700.

SAMPLING PROTOCOL groundwater resources inc. TEST BORING PROCEDURES Soil Sampling Protocol The following procedures are following during soil sampling operations utilizing the hollow stem auger drilling technique. A. Hollow Stem Auger Soil borings drilled by the hollow stem auger utilize continuous flight hollow stem augers. Augers, samplers and all downhole equipment are steam cleaned prior to use. In the field steam cleaning is done between borings to minimize the potential for cross-contamination. A G.R.I. geologist observes the work, visually logs the soils, and collects samples at appropriate intervals. The Unified Soils Classification System is utilized to classify soils encountered. Additional geological observations are noted as appropriate. Soil samples destined for laboratory analysis are collected by a modified California Split Spoon· This sampler uses three, six inch long, by two and one- half inch diameter (o.d.) tubes. Various tubes can be utilized to accommodate the type of analysis necessary: Brass All organics and general analyses (not to be used for copper or zinc analysis) Stainless Steel All organics and metals analyses for copper and zinc (not to be used for chrome or nickel analyses) Plastic All metals analyses (not to be used for organics) groundwater resources inc. TEST BORING PROCEDURES (Cont'd) 10. 11. 12. 13. 14. The tubes are cleaned and prepared in the G.R.I. laboratory. Tubes are scrubbed, inside and outside, with a brush and TSP, rinsed, dryed, and packed in clean containers with seals. Tubes are delivered to the drilling site in these closed containers to preserve the state of cleanliness. After the sample(s) have been removed from the sampler, the sampler is completely disassembled and scrubbed in TSP and tap water. It is then rinsed in clean tapwater and reassembled with three clean tubes. Dirty tubes are field'washed in TSP solution, rinsed with water, and reused. The sampler is driven by a 140 pound hammer with a 30 inch free fall. Blow counts are recorded as number of blows per inch of drive· The sampler is driven 18 inches at each sampling interval. The first (or lowest) tube is generally retained as the sample for analysis. The other two tubes are retained for back-up or split samples. A sand catcher is used in the sampler where loose soils are anticipated. This will prevent the soil from falling out of the sampler. After retrieval, the sample is visually logged and immediately sealed with aluminum foil lined caps, labeled, and chilled. Clean ice chests and chemical ice ("blue ice") are used to keep the samples cold until delivered to the chemical laboratory. Teflon seals are also available for field samples. Samples are delivered to the laboratory the same day they are taken, if physically possible. If the samples must be held until the next day, they are kept chilled in a secure location at the G.R.I. facility. Sample control is maintained by a Chain of Custody form which accompanies the sample. The form documents the time, date, and responsible person during each step in the transportation process· groundwater resources inc. MONITORING WELL SAMPLING PROTOCOL II. Groundwater Sampling Xo All equipment that is used in a monitoring well for purging, sampling, or depth measurement is decontaminated by steam cleaning or a TSP wash and rinse procedure prior to use and.before re-using when more than one sample is collected· Purge Volume Determination The following procedure is followed to determine the appropriate purging volume prior to well sampling. The depth-to-water is measured by a clean, electric level indicator. Measurement datum is the top of well protector. Depth to the bottom of the well is measured by a clean tape and plumb bob. If possible, this is compared to.the well construction log to determine inconsistencies, i.e. damaged casing, sediment in casing, etc. Water volume is calculated by using the total water depth and the inside diameter of the casing. C. Well Purging and Sampling Prior to sampling, a minimum of three to five well volumes are purged from each well to ensure that water sampled is representative of the groundwater within the formation. Measurements of H, conductivity and temperature are taken at 'frequent intervals during the purge· Stabilization of these values indicates that representative formation fluids are being removed from the well. groundwater resources inc. MONITORING WELL SAMPLING PROTOCOL (Cont'd) am In the event that the well is pumped dry, and alternate procedure will be followed· Once a well is pumped dry, the water that enters the well during recovery is, by definition, representative formation water. The well will, therefore, be pumped dry and allowed to recover to 80% or more of the original water level· Purge water is pumped directly into barrels on site until the proper method of disposal is determined. Samples are pumped or poured from a bailer into sampling bottles prepared by a state certified laboratory contracted for the particular job and placed in refrigerated coolers for transport to the laboratory. Samples are delivered by courier, directly to the lab on the same day of sampling, whenever practical. If next day delivery is necessary, the samples are kept refrigerated at 4 degrees C overnight and delivered to the laboratory the following morning. Samples are accompanied by a Chain of Custody form which documents the time, date and responsible person during each step of the transportation process· The G.R.I. coded sample numbering system allows identification of sample and client to G.R.I., while not revealing the client to anyone else.

This workplan fails to meet this Department's minimum requirements for a site characterization workplan, as described in the Handbook UT-35. Specifically, the following information must either be provided or more adequately addressed in order to meet these minimum requirements: A complete site history must be provided, including a summary of all sample analysis results regarding previous assessments, and a synopsis of all remediation actions taken at the site. This Department requires that monitoring well permits be obtained ahead of time for sites where borings will most likely impact groundwater. As has been explained to representative of G.R.I. previously, this is necessary in order to avoid delays in drilling which can prove to be very costly for the client, and to allow this Department to schedule for the time necessary to review the permit application and schedule the, inspection. Also, has monitoring well MW-2, located in the dispenser area, been sampled yet? If not, it is advised that this be done in order to provide information to better determine the placement or need for further monitoring wells before any drilling is started. An addendum containing the above information must be submitted to this Department within 15 days. If you should have any questions, please call me at (805) 861-3636.

Tank Removal Dear Mr. Starkey, Documents transmitted herewith represent the complete scope of work GRI was contracted to perform, except for the number of samples to be collected from beneath the tanks as prescribed in Handbook ~UT30. Due to extreme caving of the gravel backfill in the excavation the decision was made to eliminate some of the soil samples, especially those from six feet beneath the tanks. All soil samples from the tank excavation are reported clean. Product line samples were also clean. Soil samples from 2 ft. and 6 ft. beneath fuel dispensers at locations WP and EP were reported to contain fuel constituents. Enclosed are the following: 1) Laboratory reports on 14 soil samples 2) Chains of Custody 3) Plot Plan showing sample locations. 4) Manifest for tank rinsate.

The tank was removed under Kern County Environmental Services Department and Bakersfield City Fire Department aooroval and su0ervision. The samples were taken at deoths of two feet and six feet beneath the bottom of the tanks at points one third of the distance from the ends of the tanks. The soil type was coarse river alluvium. No staining or odor was apparent on any of the samples, and ground water was not reached. All samoies were tested for oil and grease (method 413.2) and all results were below the Minimum Reporting Level (MRL) at 50 ppm. The samples from the waste oil tank were also tested for TOX and Lead. The TOX results (method modified 9020) were less than the MRL of 1.0 0om. Of the four tests for lead (method 6010), two were below the MRL of .5 oom. The two taken at the west end of the waste oil tank at two feet and six feet were .68 opm and 1.3 Dpm (Lead), resoectively.

All hazardous waste manifests must be signed by the receiver of the hazardous waste No later than 5 working days for transportation and 14 working days for the tracking form after tank removal Sample analysis to Hazardous Materials Management Program No later than 3 working days after completion of analysis RECOMMENDATIONS/GUIDELINES FOR REMOVAL OF UNDERGROUND STORAGE TANKS This department is responsible for enforcing the Kern County Ordinance Code, Division 8 and state regulations pertaining to underground storage tanks. Representatives from this department respond to job sites during tank removals to ensure that the tanks are safe to remove/close and that the overall job performance is consistent with permit requirements, applicable laws and safety standards. The following guidelines are offered to clarify the interests and expectations for this department. Job 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, backho~ buckets are never substituted for ladders. Properly licensed contractors are assumed to understand the requirements of 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. Individual contractors will be held responsible for their post-removal paperwork. Tracking forms, hazardous-waste manifests 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.

BRIGGS ~N CfRONMENTAL HEALTH I met with Mr. Mark Crosby, of your office, on Friday, July 21, 1989. We discussed the proposed plan for the underground tanks at Golden Empire Transit. The proposal to convert the underground fuel tanks to underground fire water storage tanks is unacceptable and will not gain our approval. The site is already protected with adequate fire hydrants and fire water supply. The addition of 50,000 gallons of water in underground tanks is unnecessary and possibly confusing to fire department personnel responding to an emergency. Therefore, your request is denied. If you do desire to eliminate the use of the underground tanks, two options are available. Either remove the tanks from the ground and properly dispose of them, or abandon them in place. Abandonment in place seems consistent with your proposed plan; however, the procedure is slightly different. Rather than filling the tanks with water, they must be filled with a two sack concrete mix. The detailed procedures for either method are listed in Booklet #UT-30 from the Environmental Health Services Department. If you desire to abandon-in-place, following the guidelines in Booklet #UT-30, you will be able to gain my approval. If there are any questions, please contact my office. Very truly yours, THOMAS P. McCARTHY, CHIEF Kevin H. Scott Assistant Fire Marshal KHS/rg CC: Environmental Health Services Dept. Turonda Crumpler Protecting The Go/den Ernp/re Bill Fitzsimmons September 7, 1988 Again, I must re-iterate that this type of installation has previously not been allowed.

The words "FIRE DEPARTMENT USE ONLY" shall be on all perimeters of the tanks and in letters twelve Inches high. The words "NON-POTABLE WATER" shall be on all perimeters of the tanks and in letters twelve inches high. A reduced-pressure-principle device, approved by Kern Gounty Environmental Health Department shall be installed in the supply line. The permit can be revoked for non-compliance with any fire regulations, including but not limited to the items specified in this letter. The installation of the tanks shall meet the fo/lowing criteria: A. The tanks shall have an automatic fill device and a water level indicator. The tanks shall be manifolded togethe~ with m minimum of four inch diameter pipe· This manifold shall have single 4 1/2 inch NST male valved connection. C.

CLARK CHARLES E. DOWDY CHARLES A. VALENZUELA ADMINISTRATIVE SERVICES OFFICER NORMAN R. BRIGGS Bill Fitzsimmons P. O. Box 674 Rosamond, CA 93560 Dear Mr. Fitzsimmons: This office has reviewed your request to underground fuel storage tanks as aboveground s't~age~mor fire water. For many years, our policy has been to deny any'such request. There is no evidence or factual information indicating that these tanks will be suitable for fire water storage. However, in light of the present day abundance of used underground tanks, this office has decided to permit your request on a "test case" basis. The procedure to accomplish the permitted re-use of the underground tanks is as follows: ' 1. Follow established guidelines in Handbook UT #30 for:,the removal of the tanks. Supply written certification from the tank cleaning company, which state~ that the tanks are empty and ¢le.a~ to a "Lower Explosive Limit" of 0% The tanks shall then be removed from'the ground, set aside, and untouched for a two week period. If the Lower Explosive Limit is still 0%, a permit'will be issued by the Kern County Fire Department to allow you to utilize such tanks for fire water storage on a conditional basis. 4. The conditions of said permit will be as follows: Once the tanks are filled with water, the contents will be sampled and analyzed as to chemical make up. The flash point of the .sample will also be determined by the appropriate test method as specified in the Uniform Fire Code Standards. Results of such tests and analysis must meet with Fire Department approval. Protec/ing The Go/den Fmplre ~ Groundwater Resources, Inc. July 13, 1989 Page :3 This type of reuse of a tank has not been allowed; if a hazardous mixture is detected in testing, and/or the tanks do not meet the requirements above, the tanks will need to be removed as per Handbook UT 30. If you have any questions regarding the requirements, please do not hesitate to contact me or Dan Starkey at (805) 861-3636. Sincerely, Turonda R. Crumpler, R.E.H.S. Hazardous Materials Specialist Hazardous Materials Management Program TRC:cas Enclosures CC: Kern County Fire Deparnnent File ~xgolden.emp Groundwater Resources Inc. July 13, 1989 Page 2 Supply written approval from the Kern County Fire DeparUnent Fire Protection Program that the tanks, when cleaned of fuel residue meet the minimum specification for storage of fire supply water established by the Fire Department and other authorities. One week after the tanks are filled with water, the contents will be sampled, and analyzed as to chemical makeup, and analysis results submitted to Kern County Environmental Health Services for review. The variance, if issued after the above conditions are met the following compliance activities would be associated with it. Laboratory analyses of the stored water must be done one week and six months after the tanks are filled and once a year for 3 years. Costs incurred as results of such testing and analysis shall be the responsibility of either the facility owner and/or the contractor. A reduced pressure device, approved by the Kern County Environmental Health Services Department shall be installed in the supply line. Reuse of the underground tanks for fuel storage and/or hazardous substance will be permitted only if the tank meets all the requirements for new tank installation which include secondary contaminant requirements, overfill protection, etc. Utilization of the tank for any other purpose but storage of fire supply water would be done in violation of the variance conditions and the Kern County Ordinance Code Section 8.48.270. The permit of variance for tank disposal can be revoked for non-compliance with any Kern County Ordinance Code, including but not limited to the items specified in this letter. 2700 'IVP SIreel, Suile 300 Bakersfield, CA 93301 (805) 861.3429 Fax Number COUNTY 'OF KERN Environmental Health Services Department July 13, 1989 Groundwater Resources Inc.

The existing underground facilities include two (2) 25,000 gallon diesel tanks, one (1) 10,000 gallon gasoline tank, one (1) 2,000 gallon new motor oil tank, one (1) 4,000 gallon new motor oil and one (1) 4,000 gallon waste oil tank. We are herewith submitting applications for removal permits of the above mentioned 2,000 and 4,000 gallon tanks. However, we conceptually proposed over a year ago, in discussions with the Health Department and Fire Department, the feasibility of a closure-in-place of the larger tanks, with a variance. The variance we propose is after past site integrity and required provisions for a closure-in-place are implemented, met and approved, we'd like to use the single walled "Owens-Corning" fiberglass tanks as fresh water storage. This would provide a 60,000 gallon readily available emergency water supply for the new aboveground fuel storage facility located 75 feet from it. We are submitting with this letter our completed applications for removal/abandonment for the above mentioned tanks. We would greatly appreciate your timely response to this matter in behalf of our client, Golden Empire Transit. Sincerely, Anthony M. Ramirez Project Manager AMR:dji MAILING ADDRESS: P.O.

At their request the Kern County Health Department will be handling the remediation. The site characterization and remediation alternatives report that was submitted by Groundwater Resource Industries has been reviewed by this office. It was determined that the "Limited Excavation" alterna- tivewould be the best solution for this site. The terms of .this alternative should also include the following additions: 1. properly evacuate then sample and analyse the water collected from the w~lls referred to as ~1 and ~3 after the contaminated soil has been removed and clean soil has been backfilled; submit sample results to this office. 2. submit to this office a copy of the transportation manifest covering the shipment of the contaminated soil to a proper disposal site. 3. submit a plan addressing further water sampling if initial sample results exceed applied ~action levels.

It appears that one of the closing readings was misread as the truck and trailer combination will not hold more than about 7500 gallons. I believe the reading is high by about 10", resulting in approximately 2000 gallons difference in the total fuel delivered. As you can see, the rest of the month balances out fairly well for a variation percentage of only 1.1%. I am also enclosing a copy of the waste oil inventory control sheet. We had the oil pumped out today and I will be starting a new sheet for next week. It appears that regulations will only allow us to store waste oil for 90 days so we will be pumping this tank out on a 90 day schedule. Each time it is emptied I will send this report to you. As always, if you have any further questions~ please contact me. Sincerely, ~~aintenance Analyst /JD 1830 Golden State Avenue P.O.

However, other regulations would apply to you before you exceed 5,000 gallons of waste oil. If you have any questions or concerns, please contact me at (805) 861-3636.

Box 2870 Bakersfield, CA 93308-2870 Dear Ms. Daunell, This letter is in reference to the 4,000 gallon waste oil tank located at the Golden Empire Transit facility. You stated in a letter to this office, dated September 11, 1987, that you would pump out this waste oil tank every 90 days in order to meet regulations. If you will refer to the California Health and Safety Code, Division 20, Section 25123.3 (enclosed for your convenience), you will see that in part (1) it states that sites where wastes are contained for greater than 90 days are considered storage facilities, however, in subsection (b), it qualifies when this 90 day time period begins. This subsection states that the time period for calculating the 90 day period begins when 100 kilograms (kg) of hazardous waste or 1 kg of extremely hazardous waste is accumulated (or when any amount of hazardous waste first begins to accumulate at facilities which generate the above amounts of waste during any calendar month). A rough calculation follows as to what this amount would be in gallons for waste oil. first a) b) c) d) therefore: (d) 100 kg= 100,000 grams (g) assume the density of the waste oil to be 1 gram/liter tive estimate, remember, oil floats on water).

Reichard Judi Daunei Maintenance Analyst Golden Empire Transit District P. O. Box 2870 Bakersfield, California 93303-2870 Dear Ms. Daunel, This department has reviewed the standard inventory control monitoring worksheets for the two manifolded 25,000 gallon diesel fuel tanks at the Golden Empire Transit District facility located at 1830 Golden State Avenue in Bakersfield, California. These records indicate that this tank system is consistently unable to meet the requirements of this monitoring program. You must therefore implement one of the following methods to monitor these tanks, or you may propose an alternate monitoring program that either meets or exceeds the environmental protection offered by the standard inventory monitoring program: i. Remove and replace the existing single walled tanks with a secondarily contained system. 2. Install an electronic in-tank level sensing system that exceeds the capabilities of manual monitoring. 3. Install a ground water monitoring well. a vadose zone monitoring well, and per.form standard inventory control monitoring. This option may not be feasible due to the possibility of ground water contamination in this area. You have 30 days in which to submit a work plan and a time~able for the option that you choose. If you have any questions, please feel free to call me at (805) 861-3636.

The two (2) initial borings that were proposed in the Site Characterization Plan, dated August 4, 1987, have been drilled and completed as monitoring wells. Boring B-l, located near the leaking pu~p~ss~mbly of the tank, encountered groundwater at a depth of~16 fe~ below the surface. Drilling was completed to a depth of ~3--feet. Boring B-2, located at the dispenser area, was dri~-~ed to a total depth of 32 feet with groundwater present at~8.5 fe~ below grade. As part of the requirements set by the County (KCHD) and State (RWQCE) G.R.I. plans to complete an additional well in an at- tempt to establish a groundwater gradient. A triangular pattern will be used in order to meet this objective. The facility is located next to the Kern River adding to the complexity of the hydrogeology. Published source information (Kern County Water Agency) indicates that steep gradients are present as groundwater flows away from the river towards the valley. The permission to drill an additional well has been requested for the purpose of defining the groundwater gradient at this site. Mailing Address: P.O.

Reic, hard Judy Daunell Golden Empire Transit 1830 Golden State Avenue Bakersfield. California 93301 Dear Ms. Daunell: After careful review of the reportable inventory variations at your facility located at 1830 Golden State Avenue, Bakersfield. California (permit #060013), this Department has concluded that these results are due to a history of low throughput. This letter is to advise you that you will be granted a "provisional exemption" from the standard reporting described in your permit packet. This Department is currently undertaking a study of the inventory control problems of Iow-throughput tanks. To facilitate this, a copy of reconciliation worksheets for tanks listed on the attached outline must be sent to this Department monthly so that we may add this information to our data base. Please send all submittals to my attention. Our preliminary information indicates that a change in reportable variations is necessary when the throughput of a tank is less than 2,000 gallons per week and less than 10,000 gallons per month. The accompanying 'Low-ThroUghput Tank Reporting Outline" describes these changes. A revised action chart and an example of a changed summary sheet (on the back of inventory reconciliation worksheet} have also been enclosed for your convenience. Please make these changes on your worksheets for weeks in which you have low throughput. Be advised that this provisional exemption is subject to change as further data becomes available to the Health Department. If, however, a listed tank at any time exceeds the defined low-throughput amounts, you must revert to compliance with the original reporting requirements. If you have any questions regarding this correspondence I can be reached at (805) 861-3636 between 8 am - 9 am. Sincerely, Janis Lehman Environmental Health Specialist Hazardous Materials ~lanagement Program JL:sw Enclosures DISTRICT OFFICES Low--Throughput Tank Report1 ng Outline These amended permit requirements are only applicable to tank(s) indicated below when weekly throughput is less than 2000 ffallons and monthly throughput is less than 10~000 gallons: Effective Date: Nay 7~ 1987 Facility Permit # 060013 Tank # 2 r Unleaded Tank # 3 r 40 weight oil Tank # 4 ~ 40 weight otl Tank # n/a r n/a Amended Permit Requirements: 1.

() INTRODUCTION AND CONCLUSIONS '[i-,is r-eport presents the outcome of vadose remediation work performed and subsequent water table assessment results at the Golden Empire Transit District facility located at 1850 Golden Stat. e Avenue, . Bakersfield, California. Groundwater Resource Industries (GRI) performed the work and submits this report with the conclusion that both the vadose plume and the grounwater plume have dissipated and no further remediation is indicated. 2.0 BACKGROUND Some time shortly before July 25, 1987, an undetermined amount of unleaded gasoline was released into the backfill~ around a 10,000 gallon underground storage tank in the bus parking lot. In r~-~sponse to a request from the Kern County Health Department, a Site Characterization Plan was submitted and it was approved August 12, 1987. Augering and sampling to determine the extent o.f cont ami nat i on was performed between August 20, 1987 and September 24~ 1987. A Site Characterization Report was submitted October 20, 1987. The report described a vadose contamination plume of very limited extent in the pea-gravel back-fill below the point of release which was near the top of the ~ank. Some of '~ihe proOuct was also detected in groundwater sampled ~rom Monitor Well-1 (MW-l) which encountered the water table at about 16 feet, below 'Ehe point of release. The path 'of groundwater plume migration was identified by means of soil-gas investigation down gradient from the release point even though water samples from nW-%~., located in the path of migration, showed no hydrocabon contamination. GRI recommended that the vadose contamination plume in the pea-gravel be excavated and, following that~ a water analysis be made to determine if hydrocarbons still occur in MW- 1. The vadose plume removal was attempted November 2, 1987. GROU WATER RESOURCE INDUSTRIES Golden Empire Transit VADOSE PLUME CLEANUP OPERATIONS U~;ing a photoionization detector and sense of smell it was det~-~,rmined that the contaminated pea-gravel had dried up. Normal high temperatures dutring July, August and September increased the rate o¥ evaporation of the gasoline to the extent that the pea- gr.av(~,l: removed from what once was the vadose plume, was no ]. c,";ger contaminated · The use of shovels and a backhoe was expected to be effective in the removal of the pea-gravel, but because of flow lines, vent lines, electrical conduits and MW-1 in the area to be excavated, the backhoe was unable to work. Digging by hand with shovels was also seriously hampered b~ the piping obstacles and the pea- gravel tends to cave into 'the place where digging is attempted· A field conference was held with Mr. Tom Mele of the Kern Coqnty Health Department who,. after reviewing the facts and the si tuation ~ concluded that further excavation would be unproductive.

Laboratory Results Chain of Cui'stody Sampling Protocol GRO DWATER RESOURCE INDUSTRIES Golden Empire Transit This report presents the results of an investigation to determine the extent of contamination resulting from an unauthorized release of unleaded petroleum product at the Golden Empire Transit District facility, located at 1830 Golden State Avenue, Bakersfield, California. Groundwater Resource Industries (G.R.I.) conducted the investigation and, with this report, suggests remediation alternatives. 1.0 BACKGROUND On June 19, 1987, GRI performed a F'etro-Tite Line Test on the product line from a 10,000 gallon underground storage tank. The ii~e passed the test at a .040 gallon per hour rate. Subsequently, on July 23, 1987, at the request of the Kern County Health Department, GRI attempted to perform a Petro-Tite Line Test on that same line. ]'he test was aborted because the line could not be brought up to the required test pressure. A damaged br.a~ss sealing ring on a 2" union connected to the Red Jacket line leak detector was replaced and a faulty 1-1/2" impact valve from the dispenser area was replaced. Following a successful twenty- two hour air pressure test the product line was refilled with unleaded gasoline and passed .a F'etro-Tite Line '[est. An undetermined amount of unleaded gasoline was discharged into the soi 1 near the Red Jacket 1 ine 1 eak detector. The contaminated soil which was excavated during repair operations has been placed in two fifty-five gallon DOT 17H drums located r'~ear the excavation. A Site Characterization Plan, dated August 4, 1987, to define the vert :[ cai and hot i z ontal ex tent of the cont ami nat i on, was submi t{:ed to Ms. Jani s Lehman of the Kern County Heal th Department. The plan was approved on August 12, 1987 and the proposed work was performed-between August 20, 1987 and September 24, 1987. SOIL ~ORINGS AND~"=~MMFLING' ' F'ROCEDURES iS.R~ I. 's workplan initially consisted of three borings, one at the tank location near the Red Jacket line leak detector, one at the d~ispenser area~ and one centrally located in the downgradient ar'ea over].ying a suspected groundwater contamination plume (Plot F'lar~, Plate 2). These boring~ were completed as groundwater GROU WATER RESOURCE INDUSTRIES Golden Empire Transit monitoring wells using 2-inch diameter schedule 40 PVC with .020- inch ~actory perforations. The third boring was drilled based on the laboratory results o¥ borings I and 2, and on a soil-gas inves'~igation designed to define 'the boundries and direction of the grc)undwater plume. The borings were made with nine-inch diameter, continuous-flight hc)llow stem auger equipment. Drilling was performed by Melton Drillin,~ ,~f Bakersfield, California under the supervision of a G.R.I. geologist. The cores were taken with a California Split Spoon Sampler and described as they were acquired. A log o~ each b~ring is presented in Plate ~. Soil samples intended for laboratc~ry analysis were sealed, labeled, and placed on ice for transport to a cer'ti~ied laboratory. A (_-hain of custody (Appendix B) was maintained for all the samples. Boring B-1 was drilled to a total depth of 30 feet wi th groundwater encountered at approximately 16 feet. Boring B-2 was drill(~d '~_o 32 feet with groundwater encountered at approximately 16 .~eet. Boring B-3 was drilled to 39 feet with groundwater encountered at approximately 16 feet. See Boring Log (Plate ~ci~r we].], construction information. Augers and downhole equipment, including samplers, were steam cleaned between successive borings to avoid contamination, according to the Sampling Protocol presented in appendix C. In addition,· each soil sample obtained was tested on-site for Total Petroleum Hydrocarbons (TPH) concentrations using a TIP photoionization detection meter. ~S. 0 SOIL-GAS INVESTIGATION Soil-gas investigation refers to the analysis of the soil-air in the vadose zone as a means to l oca'~e suspected underground cc, ntam'~.nation from volatile organic chemicals (VOCs) including pet. roleum products. This technique of contaminant mapping is very cost-efYective since it provides a rapid means of collecting data, at the project site, without the cost and time delays a-s~sc, cia'ked with conventional drilling and sampling. Numerous samples can be collected over a large area which increases the pl'"obabi 1 i ty of detecting and defining the boundaries of a contamination plume. GRO DWATER RESOURCE INDUSTRIES Golden Empire Transit The Golden Empire Transit site was characterized by suspected contaminated groundwater at approximatly l& feet in depth overlain by medium to coarse grained sands, indicating a large amount of air-filled porosity into which the gasoline vapors could migrate. Tine objective of the soil-gas investigation employed by G.R.I. was to obtain information as to the boundaries of the plume, its direction of flow, and a quantitative estimate of the concentration levels within its plume. This data was then used to locate a third monitoring well. Although gasoline is a mixture of over 200 petroleum-derived chemicals, analysis of the gasoline components is usually limited to the detection of Benzene, Toluene, Xylene and Total Volatile Hydrocarbons (TVH). Those constituents possessing high vapor pressures, low molecular weights, and low aqueous solubilities readily partition out of the groundwater and into the soil-gas zone enabling detection by portable monitoring equipment. Tine procedure for collecting the data involved using the auger equipment described in section 2.0 above, sampling at depths of ~9, 14, and 16 feet using the Split spoon sampler. The bottom of the acquired brass tube was covered with sterilized gauze allowing air to flow through the tube. TVH in parts per million (ppm) was then measured using the TIP photoionization detection meter to extract and analyze the vapors. Additionally, an auger hole was drilled and sampled upgradient and outside of the contaminated area to determine what the ambient readings would be on clean soil at the facility site. This data will serve as a guide to determine the plume's boundry. A summary of data collected from each auger hole location is presented in Plate 4. A contour map showing TVH (Plate details 'the readings observed at 14 and 16 feet for the auger hole locations. Based on this information, it was decided to locate 'the third monitoring well between auger holes A-9 and A- 4.0 FINDINGS 4..1 Laboratory analysis of Soil Samples Soil samples taken from boreholes B-l, B-2, and B-3 were anlayzed by B.C. Laboratories of Bakersfield, California, using EPA RESOURCE INDUSTRIES Golden Empire Transit 5020,."8C, 2C~ method to determine BTX-TPH concentration of cc, nstituer'~ts present. gasol i ne The analyses on soil samples from boring B-1 indicate below action level contamination -~or soil down to ..-~ feet and non- detectable amounts at 29 feet. The concentration levels for Total F'~.~troleum Hydrocarbons (TPH) ranged in value from 174 ppm at. 16 .~ee~ to 56 ppm at 20 feet to 148 ppm at 25 feet. B()ring B-2, located by the dispenser., had non-detectable amounts of contamination from 5 feet down to the total depth of 30 feet. Soil samples analyzed for boring B-3 also revealed non-detectable amounts o¥ contamination within the soil. Laboratory' r-esul'ts ~in Appendix A. 4.2 Laboratory Analysis of Water Samples Twenty--four hours after completing 'the monitoring wells, the water was sampled using a teflon bailer. Four well volumes were purs!e~ from each well to ensure a representative sample was taken from the aquifer. Two water samples ta~:!en from each well and a t-ravel blank were sent to B.'C. I_aboratories to be analyzed for BTX-TF'H us.sing EPA 602 method. Groundwater samples from MW-1 (Boring B-l) revealed a high cc~.nc,en'i-ration of 5.10 par-ts per billion (ppb) and 9.:]6 ppb for Benzene fram the two samples. Toluene concentrations were 7 ppb t() 36 ppl.)~ respectively and the total Xylenes were 2502 ppb to 216~ ppb~. respectively. Groundwater samples from MW-2 (Boring B-2) showed no reportable levels c)f con'tamination from either sample. One of the water samples from MW-3 (Boring B-3) ~ collected Sept-ember 30, 1987, reported 1.6 ppb Benzene and 1.6 ppb TF'H, while anaiytes in the second sample were all below minimum rep(~rting l~vel. The B.C. Labora'~ories analyst who ran those ~u.l-~.es explained the difference between the two 5 ml sample runs · as a possible interferen~_-e due to a 'trace amount of Benzene in the lal.~ equipment (see letter, Appendi;..' C). MW-3 was resampled ar'id 25 m'l. samples were analyzed to avoid interference due to pc)ssible hydrocarb'~n residuals in the lab equipment. Groundwater samples Yrom MW-5 showed no repor'~able levels of contamination. Th~, travel blanks, analyzed for the same constituents as the wat. e~ .... s~amples, indicated no detectable levels of contamination. 4 GRO DWATER RESOURCE INDUSTRIES Golden Empire Transit 4.3 Geology and Hydrogeology The project site is located on the west-side of the San Joaquin Valley bordering the Sierra Nevada Mountains. Surface geology at this location consists of Sierra Nevada provenance alluvial fan material. Theme Pleistocene continental deposits were derived from the erosion of hard crystalline granitic rocks by the Kern River and laid down as coalescing alluvial fans. The Kern River Alluvial fan lies along the river between Bakersfield and Oildale. and radiates out into the valley in a 1lO-degree arced fan sloping approximately 7 feet per mile. ]'he sediments penetrated by the borings are comprised of loosely compacted silts to 10 feet and poorly sorted sands, commonly containing pebbles and cobbles, to 55 feet. The silts were brown to grey in coloring with occassional rust colored mottling and were only slightly plastic. The sands were grey and brown in color~ micaeous, and silty with low plasticity and contained layers of one-inch pebbles and cobbles. Kern County Water Agency' (KCWA) reported depth to unconfined groundwater in 1986 (most recent report) to be less than 50 feet below ground level at this site. During the drilling process groundwater was encountered at approximately 16 feet below grade in borings B-l, B-2 and B-5. The Kern River,located approximately one-half mile to the northwest, serves, as the primary natural and artifical recharge to the groundwater basin. According to the KCWA, the direction of groundwater movement is away from the Kern River in a southeasterly direction with a gradient of approximately 75 feet per mile. The results from G.R.I.'s soil-gas investigation would suggest a south to southeasterly flow direction based on the direction of the contamination plume within the groundwater. The average rainfall in the vicinity of the site, based on a 20 year average, is estimated at 5.5 inches. As measured at the Bakersfield Airport, located 2.25 miles to the northwest, 50 percent of the average precipitation occurs in the winter (January, February, March) and only 2.percent during the summer (July, August, September). 5.0 CONCLUSIONS REGARDING THE CONTAMINATION PLUME 5.1 Vadose Zone Plume The location of the contamination release was found to be in the 5 GRO iDWATER RESOURCE INDUSTRIES Golden Empire Transit area of the Red Jacket line leak detector on the 10,000 gallon unleaded gasoline tank. The tank rested on a concrete slab approximately two feet thick. Pea-gravel was used as a fill above the concrete slab and surrounding the tank. Below the concrete slab'was undisturbed soil. F'late 5 shows a cross section of the plume in the vadose zone. Due to the high permeability of the pea-gravel and the lack of undisturbed soil between the tank and groundwater, liquid contamination would percolate downward with little lateral extent. The soil from the four-foot deep excavation around the turbine pump contains contamination from the spill and is presently covered,on-site, with polyethlyene sheeting. 5.2 Groundwater Plume As discussed in section 5.1 above, contamination from the release quickly migrated through the fill into the groundwater. Laboratory analysis of groundwater from borings B-2 (MW-2) and B..-5 (MW-5), however, indicated non-detectable levels of contamination present. The location of MW-2 is believed to be just outside the direction of groundwater flow downgradient from MW-1. MW-3, located approximately 5~ feet south-southeast of MW- 1 is believed to be in the heart of the suspected plume based on tine data collected from the soil-gas investigation (see Plate 5). The rate of groundwater flow has not. been determined nor is it available in the source literature due to seasonal variations and other variables such as recharge and discharge rates and the fa~t that the Kern River is a controlled flood channel. It is important to note however that 1986-87 was a dry season and that flow from the Kern River is slow throughout the summer months. Based on the laboratory analyses, the soil-gas investigation, and the hydrogeological data available it appears as if the groundwater plume migrated south-southeast with some of the volatiles partitioning out into the soil-gas zone. Those volatiles that don't readily partition out are more water soluable and have lower vapor pressures. It has been found that soils pr-edominantly contaminated by migrating vapors, rather than liquids, will show higher field values than laboratory values because the photoionization detector extracts vapors from a large volume of relatively undisturbed soil within the brass core-tube, while the lab analyst takes only one or two grams of sub-sample 6 GROI DWATER RESOURCE INDUSTRIES · ! Golden Empire Transit and aerates it in the process of handling it. This was confirmed by the soil-gas investigation which essentially defined the pathway of the plume even though groundwater contamination is no longer detectable downgradient from the release. 5.5 Near-Term Threat Due .to Plume in Vadose Zone ]'he source of contamination (i.e. the area of the Red Jacket line leak detector) is located in the middle of the bus parking lot at the project site which is sealed by asphalt and concrete paving. The near-term threat to biological receptors is minimal due to the remote and secured location of the contamination and because a large part of the contaminated soil has. been removed during the repair operations on the leaking pipe-union. Several factors needed to be addressed because there still exists the potential for near-term problems. The presence of buried pipes and structures in the immediate area might serve as conduits for migrating vapors which in turn might collect beneath the paving in an explosive concentration. A wash rack for the buses is located approximentely seventy feet northeast of the source of contamination. This, combined with precipitation, could flush any remaining contamination down into the groundwater. Finally, there'is also the possibility of water- level flucuations as' a result of the Kern River rising and falling. This could effectively wash contaminants from the base of the vadose plume into the groundwater. 5.4 Near-Term Threat Due to Plume in Groundwater As previously discussed, the amount of gasoline released into the soil is small. The soil-gas investigation revealed 'the direction of the groundwater plume by tracking the remnant vapor concentrations that partitioned out into the soil-gas zone above th~ water table. Subsequent borings showed that the groundwater plume is no longer detectable at MW-5, indicating that the plume has dispersed into very low concentration levels. The cost associated with assessing the extent of the plume outside the Golden Empire Transit District facility versus the threat imposed by it would be inordinant because the threat is minimal. Many of the same concerns discussed under Section 5.5 would apply to the groundwater, since any contamination in the vadose zone can affect the groundwater zone should leaching occur. Therefore, it is the opinion of G.R.I. that remediation be directed at removing the conta~ninated soil in the vadose zone followed by a water analysis to determine if the plume still exists at MW-1. 7 GROL DWATER RESOURCE INDUSTRIES Golden Empire Transit 5.5 Long Term Effects '[he long term threat of the vadose and groundwater plumes to biological receptors would be minimal under existing conditions. However, should the facility be altered or put to some other use that might uncover the contamination in the process, the risk of exposure to bioreceptors (people) would increase. 6. 0 REMEDIATION ALTERNATIVES 6.1 Limited Excavation Limited excavation is considered to be the quickest and most economical method of remediation. The pea-gravel beneath the Red Jacket line leak detector should be removed as well as any soil beneath the tank down to the groundwater table. On-site monitoring with a photoionization meter should be used to determine when all of the contamination has been removed. All excavated soil, including the contamination contained within the soil presently stored at the surface, should be manifested and disposed of at an appropriate site. Clean backfill should be used to restore the excavation to grade. 6.2 Vapor Extraction The second most favorable form of remediation would be to use the existing monitoring well as an extraction well whereby the volatiles are extracted and filtered using activated carbon drums. Operations would cease when extracted gases meet the concentration levels set by the county. The time required to achieve an acceptably low level of contamination may be as little as a few weeks to a few months. 6.3 No Action The "no-action" alternative would allow the diffusion and natural degradation to destroy the plume over a very long period of time.

Lab. No's 20425, 20426, 20924-1 GRI Project No. 06187 Gentlemen, This letter is to confirm my telephone and in-person conversations with Terry Rowles on October 15, 1987. As per my understanding BC Laboratories was ex- periencing background contamination of benzene prior to the analysis of water samples (MW3-1 and MW03-1 collected September 30, 1987) from project number 06187. You explained that a 5 ml quanity of sample is analyzed and that the background levels of benzene in this small of quanity could show up as being slightly above the minimum reporting level. To.resolve this conflict you sug- gested analyzing a larger quanity (25 ml). You also indicated at this time that these additional samples would be processed free of charge. Based on this information, G.R.I. obtained two (2) water samples and had them analyzed on October 15, 1987. Sample identification information is as follows: Samples- MW3-1, MW3-2, Travel blank Lab.

RESOURCE INDUSTRIES APPL~DZX C. TEST BORING PROCEDm%ES Soil Sampling Protocol The following procedures are followed during soil sampling operations utilizing the hollow stem auger drilling technique. A. Hollow Stem Auger Soil borings drilled by the hollow stem auger utilize continuous flight hollow stem augers. Augers, samplers' and all downhole equipment are steam cleaned prior to use. In the field steam cleaning is done between borings to minimize the potential for cross-contamination· A G.R.I. geologist observes the work, visually logs the soils, and collects-samples at appropriate intervals. The Unified Soils Classification System is utilized to classify soils encountered. Additional geologic observations'are noted as appropriate. Soil samples destined for laboratory analysis are collected by a modified CaLifornia Split Spoon. This sampler uses three,, six inch long, by two inch diameter (o.d.) tubes. Various tubes can be utilized to accommodate the type of analysis necessary:. Brass Stainless Steel Plastic Ail organics and general analyses (not to be used for copper or zinc analysis). All organics and metals analyses for copper and zinc (not to be used for chrome or nickel analyses) All metals analyses (not to be used for organics) GROUNDWATER RESOURCE INDUSTRIES ~ppendix 0 (cent"d) The tubes are cleaned and prepared in the G.R.I. laboratory. Tubes are scrubbed, inside and outside, with a brush and TSP. They are next steam cleaned, and packed in clean containers with seals. Tubes are delivered to the drilling site in these closed containers to preserve the state of cleanliness. .. After the sample(S) have been removed from the sampler, the sampler is completely disassembled and scrubbed in TSP and tap water. It is then rinsed in two separate tapwater baths and re- assembled with three, clean tubes. Dirty tubes are field washed.in TSP, rinsed with water, and placed in buckets for transport back to the G.R.I. lab for cleaning and preparation. 9. The sampler is driven by a 140 pound hammer with a 30 inch free fall. Blow counts are recorded as number of blows per 6 inches-of drive. 10. The sampler is driven 18 inches at each sampling interval. The first (or lowest.) tube is generally retained as the sample for analysis. The other two tubes are retained for. back-up or split samples. 11. 12. 13. 14. A sand catcher is used in the sampler where loose soils are anticipated. This-will prevent the soil from falling out of the sampler. After retrieval, the sample is. Visually logged and immediately sealed with. aluminum foil .lined caps, labeled, and chilled. Clean field ice chests and chemical ice ("blue ice") are used to keep the samples cold until delivered to the chemical laboratory.

On July 23, 1987, G.R.I. conducted a Petro-Tite Line T~st on the unleaded product line of a 10,000 gallon underground storage tank. This tank has been in place for approximately four years and has passed a Petro-Tite precision test. The line test failed. After excavation of the tank turbine pump area and product lines, a dam- aged brass sealing ring on a 2" union connected to the Red Jacket line leak detector at the tank was found and replaced. Upon re- moval of a 1-1/2" impact valve from the dispenser area the line held pressure. After a successful 22 hour air pressure test on the isolated product line, a Petro-Tite Line Test was conducted on July 31, 1987, 'fcllowing the re-filling of the line with unleaded gasoline. The line passed Kern County Environmental Health re- gulations at +.000 G.P.H. Discrepancies in inventory monitoring suggests that there has been a loss of product in the tank. Approximately 3 to 5 gallons of unleaded gasoline was discharged into the soil near the Red Jacket line leak detector. Two 55 gallon DOT 17H drums contain contaminated soil from this spill. Because of the known leakage from the product line, we have prepared the following plan to define both the vertical and horizontal extent of any soil contamination or discharge. Groundwater is reported to Mailing Address: P.O. Box 9383, Bakersfield, California 93389 Other Locations: San Jose · San Ramon · Campbell · Los Angeles Ms. Janis Lehman Kern County Health Department Environmental Health Division August 4, 1987 Page Two to be at an approximate depth of 16 feet. Initially, we recommend two (2) boring locations drilled to groundwater. The proposed soil boring locations (see Plate 2, Plot Plan) include: (1) boring at the tank location near the leaking pump assembly and (1) boring at the dispenser area. Undisturbed soil samples will be taken at plan- ned intervals every five (5) feet. During the boring project all borings will be logged by a G.R.I. geologist. All samples will be sealed, labeled and chilled on location and then transported to a State Certified laboratory. The samples will be analyzed for Benzene, Toluene, Xylene and Total Petroleum Hydrocarbons (TPH). Chain of custody records will be kept on all samples. If the initial planned borings reveal obvious contamination in the soil profile down to groundwater, as measured on-site with a photo- ionization meter or LEL Meter, then a more detailed site characteri- zation would be initiated to identify the extent of groundwater pollution. The borings would be completed as groundwater sampling wells following company protocol, which is enclosed for your review. After the borings are conducted and samples are analyzed, a report will be prepared for your office with. all results, logs, laboratory analysis, hydrogeology, definition of the contamination and a recommendation of remedial action alternatives. We have not as yet identified the proper method for mitigation of this site. Upon completion of the proposed work, we will explore the site specific alternatives. The final mitigation technique will be designed on field results as outlined above. Ail work will be supervised by our Staff Registered Geologist, Mr. Rex Young (State Registration ~720). In order to conduct the borings, the personnel on site will be equipped with a Draeg~r PA-80 Air Pack, Gastech D-II Vaportester or equivalent, fire extinguishers and any additionally required equipment for health and safety considerations.

ACCEPTED BY ~(-~z/. ,~~ DATE .-/ GROUNDWATER RESOURCE INDUSTRIES APPENDIX A SAMPLING PROTOCOL GROU WATER RESOURCE INDUSTRIES APPENDIX A TEST BORING PROCEDURES Soil Sampling Protocol The following procedures are followed during soil sampling operations utilizing the hollow stem auger drilling technique. A. Hollow Stem Auger Soil borings drilled by the hollow stem auger utilize continuous flight hollow stem augers. Augers, samplers and all downhole equipment are steam cleaned prior to use. In the field steam cleaning is done between borings to minimize the potential for cross-contamination. A G.R.I. geologist observes the work, visually logs the soils, and collects samples at appropriate intervals. The Unified Soils Classification System is utilized to classify soils encountered. Additional geologic observations.are noted as appropriate. Se Soil samples destined for laboratory analysis are collected by a modified California Split Spoon. This sampler uses three, six inch long, by two inch diameter (o.d.) tubes. Various tubes can be utilized to accommodate the type of analysis necessary:. Brass Stainless Steel Plastic Ail organics and general analYses (not to be used for copper or zinc analysis) All organics and metals analyses for copper and zinc (not to be used for chrome or nickel analyses) All metals analyses (not to be used for organics) GRO WATER RESOURCE INDUSTRIES Appendix A (cont'd) The tubes are cleaned and prepared in the G.R.I. laboratory. Tubes are scrubbed, inside and outside, with a brush and TSP. They are next steam cleaned, and packed in clean containers with seals. Tubes are delivered to the drilling site in these closed containers to preserve the state of cleanliness. After the sample(s) have been removed from the sampler, the sampler is completely disassembled and scrubbed in TSP and tap water. It is then rinsed in two separate tapwater baths and re- assembled with three, clean tubes. 8. · Dirty tubes are field washed.in TSP, rinsed with water, and placed in buckets for transport back to the G.R.I. lab for cleaning and preparation. The sampler is driven by a 140 pound hammer with a 30 inch free fall. Blow counts are recorded as number of blows per 6 inches of drive. 10. The sampler is driven 18 inches at each sampling interval. The first (or lowest) tube is generally retained as the sample for analysis. The other two tubes are retained for back-up or split samples. 11. A sand catcher is used in the sampler where loose soils are anticipated. This will prevent the soil from falling out of the sampler. 12. After retrieval, the sample is. Visually logged and immediately sealed with aluminum foil .lined caps, labeled, and chilled. Clean field ice chests and chemical ice ("blue ice") are used to keep the samples cold until delivered to the chemical laboratory. Teflon seals are also available for field samples. 13. 14. Samples are delivered to. the laboratory the same day they are taken, if physically possible. If the samples must be held until the next day, they are kept frozen in a secure freezer at the G.R.I. facility. Sample control is maintained by a Chain of Custody form which accompanies the sample. The form documents the time, date, .and responsible person during each step in the transportation process.

The assessment was done to investigate the impact of diesel fuel contamination on the soil beneath the facility's fuel dispensers and to detennine whether groundwater has been affected. Soil samples collected from beneath the fuel dispensers and related pipelines on October 10, 1989 (see closure report dated December 6, 1989, permit #A972-06), showed that soil at 2 feet and 6 feet beneath the dispensers and associated pipelines contained substantial levels of Total Petroleum Hydrocarbons as Diesel and low levels of volatile organic compounds (BTXE). As a result, on June 20, 1990 four soft borings were augeredin the locations shown on the attached plot plan, Plate 2, and samples were collected at 5 feet intervals to delineate the vertical and horizontal extent of the soft contamination plume. Due to the shallow groundwater levels in the area (as shallow as 18 feet), one of the borings was completed as a groundwater water monitoring well, labeled MW-6, which is placed down-gradient from the fuel dispensers. The results of the initial sampling beneath the dispensers and adjacent pipelines at 3 feet and 7 feet are summarized here.

The minimum reporting levels for the water test are .5 and 500 ppb, respectively. h can be seen that the only positive results occurred in boring B-3 at a depth of 10 feet. This was accompanied by a fairly strong odor of diesel fuel and a reading of 70 ppm for total volatile organic vapor on a portable PID meter. A very faint odor was found at 15 feet, but the lab analysis showed no detection of hydrocarbons there. Detection of a faint fuel odor at 20 feet in that boring was recorded as "possible". All other boring samples showed no hydrocarbon staining, odor or meter readings. Because of the hydrocarbons detected in B-3, all the soil cuttings from this boring were set aside and covered with a plastic sheet, and the boring was baclff'tlled with a bentonite-cement slurry. AUGUST 10, 1990/Page 3 GROUNDWATER RESOURCES INC. GOLDEN EMPIRE TRANSIT 2.2 Vertical and Lateral Extent of Contamination Since the four new soil borings show s° little hydrocarbon contamination it is necessary to incorporate the manual borings done on October 19, 1989 into the cross sections attached as Plates 3 and 4. The cross sections indicate that the soil contamination is limited to a depth of 15 feet and a diameter of 10 to 12 feet. There is one plume under each dispenser of similar dimensions. 2.3 Description of Borings The borings were drilled using 8 inch diameter hollow stem continuous flight augers. Undisturbed soil samples were collected at 5 feet intervals in 2 inch by 6 inch brass tubes mounted in a California Split-Spoon Sampler. Upon receiving the sample on the surface, the geologist sealed the ends of the second of three tubes with teflon, labeled the sample and refrigerated it immediately. One of the other two sample tubes would then be described according to the Unified Soil Classification System, metered with a Photo-Ionization Detector meter and logged. The samples were then transported to BC Laboratory under a chain-of-custody document and analyzed for BTXE using EPA method 5030/8020 and for TPH (Diesel) using the D. O. H. S. LUFT Manual Method. The Sample descriptions and field data are annotated to the attached boring logs, plates 5 through 8. The manual borings shown on the cross sections were placed as close to the dispensers as possible and were under the piping leading to the dispensers. Samples were collected at depths of 2 feet and 6 feet below the pipelines which were one foot below the surface. Borings B-3 and B4 were angle drilled so that the bottom of the holes would cross under the dispensers and the previous sampling locations. Since contamination was already documented at depths to 7 feet, no samples were collected at 5 feet in the vertical extent borings, B-3 and B-4. Borings B-5 and MW-6 were located at distances of 6 and 8 feet from the dispensers to define the horizontal extent of the plumes. No indication of hydrocarbons at this distance was found. MW-6 was placed in a down-gradient direction from the dispensers. Placement of the borings was restricted by the narrow spacing between the islands and by the overhead canopy. 2.4 Monitoring Well Construction Monitoring well MW-6 was completed as diagrammed in plate number 8. Groundwater was expected to be found at about 18 feet from the surface, and the workplan and well permit were written accordingly. Groundwater was actually found at 25.07 feet. This greater than expected chop in the water table dictated a longer than planned screened interval. The well was drilled to a depth of 35 feet and the well screen was set in place at 33.9 feet inside the augers, and the augers were then withdrawn. Heaving sand precluded f'flter packing the interval below the water table, however, the native soil type was clean, coarse river sand, and the productivity of the well will be high. The well screen was extended to 13.9 AUGUST 10, 1990/Page 4 GROUNDWATER RESOURCES INC. GOLDEN EMPIRE TRANSIT feet of depth to keep the top of the screen above the high water table level On Sune 26, 1990, the well was purged of more than three well volumes and sampled for BTXE and TPH (diesel); there were no hydrocarbons detected in the groundwater. 3.0 Remedial Action Options Regardless of thc option chosen, Groundwater Resources, Inc. recommends that the possibility of future fuel spills contributing to soil contamination be eliminated by careful sealing of the concrete pad. All pipeline trenches should be excavated of soil and filled with concrete as well as the openings through the pad beneath the fuel dispensers. 3.1 No Action 3.11 Description Since the contaminated soil lies within 25 feet of the minimum distance to groundwater, the Ca!ifomia LUFf Manual Risk Appraisal cannot be used and the maximum allowable TPH Diesel level of 100 ppm does not apply. The no action option is not recommended for consideration. 3.2 Excavation and Removal Of the three options listed here, only excavation and removal immediately reduces hydrocarbon levels to non-detectable and provides a positive means of closure in a reasonably short time. GRI recommends that excavation and removal of the soil from the subsurface be the option used. 3.21 Description Excavation of the contaminated soil involves shutting down and temporary, removal of the dispenser pumps and cutting the concrete pad in a circle about 15 feet in diameter over the center of the plumes. The soil could then be removed directly with a backhoe. The method of remediafion of the soil on the surface will be determined when the volume and contaminant concentrations are known, but it is very likely that the soil can be aerated on the surface. '-~-'~v,_zJ (.~) Since the contamination appears to be in two distinct plumes, one associated with each dispenser, it may be most practical to treat one plume at a time; this will allow the fueling station to remain in service and minimize disruption of normal operations. AUGUST 10, 1990/Page 5 GROUNDWATER RESOURCES INC. I GOLDEN EMPIRE TRANSIT I~ 3.22 Feasibility and Cost The entire plume will be accessible by use of an extended reach back hoe. GRI estimates that it will take one day to excavate and one day to backfill and compact each excavation. The primary costs involved are four days of backhoe work, hauling of the removed concrete, hauling in of backfill material and repair of the pad. A construction supervisor and geologist should ~e onf!ocation. The total job cost should be well under $180005.;:^{,.,~ ~ ~ ' . .~.-~ 3.23 Expected Concentrations After Remediation The contamination level in the soil can be monitored during the excavation, and State certified samples can be collected from the bottom and sides of the excavation for confu'mafion that no detectable hydrocarbons remain. This precludes the need for a risk appraisal or for long term monitoring. 3.3 Vapor Extraction 3.31 Description Vapor extraction of soil gases will remove the volatile components of the fuel, but will not directly remove the non-volatile oils. Rather, by supplying a flow of fresh air through the plume, degradation of the non-volatiles by weathering will be accelerated substantially when compared to anaerobic conditions. The total time required to achieve acceptable levels is still unpredictable. This option will require the construction of two vapor extraction wells in the center of the plumes, plumbing to a large displacement vacuum pump and a means of vapor collection or thermal oxidation. Additionally, an AQMD permit will be required to operate, and this will call for c~o..ntinuous monitoring of emissions. The most practical means of handling diesel vapors of this small volume is with granular activated carbon adsorption. 3.32 Feasibility and Cost The initial costs of this method will be similar to the costs of excavation and removal. However, vapor extraction will also incur extra costs in maintenance and monitoring on a regular interval, and closure will require confn'mation soil borings and sampling. 3.33 Expected Concentrations After Remediation In sandy soil of this type, it is likely that BTXE can be reduced to non-detectable levels within several months. However, TPH as Diesel will decline more slowly. Due to the proximity to groundwater, the usual maximum allowable TPH CD) of 100 ppm does not apply. Very low to non- detectable levels of TPH must be achieved to obtain closure, and this may take more than one year. AUGUST 10, 1990/Page 6 GROUNDWATER RESOURCES INC. GOLDEN EMPIRE TRANSIT 3.34 Monitoring of Vapor Exu'action System A vapor exu'acfion system requires continuous operation of a surface facility including motors, vacuum pumps, carbon drams and associated sensors and recording equipment. Maintenance of this equipment will be required at least twice per month for the duration. Also, soil samples will have to be collected approximately once every two months to monitor the progress of the project. Of the three options listed here, vapor extraction will likely incur the highest cost as well as a long and uncertain duration. GRI does not recommend the use of this option.

Laboratory Results Chain of Cu'stody Sampling Protocol GRO DWATER RESOURCE INDUSTRIES Golden Empire Transit This report presents the results of an investigation to determine the extent ~f contamination resulting from an unauthorized rel ease of unleaded petroleum product at the Golden Empire Transit District facility, located at 1830 Golden Stat~ Avenue, Bakersfield, California. Groundwater Resource Industries (G.R.I.) conducted the investigation and, with this report, suggests remediation alternatives. 1 .. 0 BACKGROUND On June 19~ 1987, GRI performed a Petro-Tite Line Test on the product line from a 1F~,C~('~A ~allon under~round st~ra e tank The ~ubseque"~tly~ on July .~3~ 19~ at the r-equest ~ the Kern County Health Department~ GRI attempted to per-~orm a Petro-Tite Line Test on that same line. The test was aborted because the line could not be brought up to the required test pressure. A damaged brass sealing ring on a 2" union connected to the Red Jacket.line leak detector was re~}_Dced and a ~aulty 1-1/2" i_~)pact valve ~rom ')~~ens~r ~ ~-~~. Eol~o~ing ~ ~u~ess~ul twen~y- t,,~o hour air pre~sure test the pr-oduct line was refilled with unl,:~aded gasoline and passed .a Petro-Tite Line Test. An undetermined amount- of unleaded gasoline was discharged into the sol i near 'hhe Red Jacket 1 ine 1 eak detector. The conZaminated soil which was excavated during repair operations has been placed in two fifty-five gallon DOT 17H drums located near the excavation. A Site Characterization Plan, dated August 4, 1987, to define the vertical and horizontal extent of the contamination, was submi ti:ed to Ms. Jani s Lehman of the Kern County Heal th Depart. ment. The plan was approved on August 12, 1987 and the proposed work' was performed .between August 20, 1987 and September 24, 1987. 2.0 SOIL BORINGS AND SAMPLING F'ROCEDURES G.R.I. 's workplan initially consisted of three borings, one at the tank location near the Red Jacket line leak detector, one at the dispenser area~ and one centrally located in the downgradient area overlying a suspected groundwater contamination plume (F'lot Plan, ;---'late 2). These borings were completed as groundwater GROU WATER RESOURCE INDUSTRIES Golden Empire Transit monitoring wells using 2-inch diameter schedule 40 PVC with .020- inch factory perforations. '[he third boring was drilled based on the laboratory results of borings i and 2, and on a soil-gas investigation designed to define the boundries and direction of the groundwater plume. The borings were made with nine-inch diameter, continuous-flight hollow stem auger equipment. Drilling was performed by Melton Drilling of Bakersfield, California under the supervision of a G.R.I. geologist. The cores were taken with a California Split Spoor'~ Sampler and described as they were acquired. A log of each boring is presented in F'late 3. Soil samples intended for 1,.-::'~bc~ratory analysis were sealed, labeled, and placed on ice for transport to a certified laboratory. A chain of custody (Appendix B) was maintained for all the samples. Boring B-1 was drilled to a total depth of .~0 groundwater encountered at approximately 1~ feet. Boring drilled to 32 feet with groundwater encountered at approximately 16 feet. Boring B-.3 was drilled to 39 feet with groundwater encouptered at approximately 16 feet. See Boring log (Plate' ~:or well construction information. Augers and downhole equipment, including samplers, were steam cleaned between successive borings to avoid contamination, according to the Sampling Protocol presented in appendix C. In addition, each soil sample obtained was tested on-site for Total F'etroleum Hydrocarbons (TPH) concentrations using a TIP photoionization detection meter. :3.0 SOIL-GAS 'INVESTIGATION Soi].-gas investigation refers to the analysis of the soil-air in · !::he vadose zone as a means to locate 'suspected underground contamination from volatile organic chemicals (VOCs) including petroleum products. '[his technique of contaminant mapping is very cost-effective since it provides a rapid means of collecting data, at the project site~ without the cost and time delays as-:.sociated with conventional drilling and sampling. Numerous samples can be rollected over- a large area which increases the pr,:.~bab i 1 ity of detecting and defining the boundaries of a contamination plume. 2 GROUNDWATER RESOURCE INDUSTRIES Golden Empire Transit The Golden Empire Transit site was characterized by suspected contaminated groundwater at approximatly 16 feet in depth overlain by medium to coarse grained sands, indicating a large amount of air-filled porosity into which the gasoline vapors could migrate. The objective of the soil-gas investigation employed by G.R.I. was to obtain information as to the boundaries of the plume, its direction of flow, and a quantitative estimate of the concentration levels within its plume. This data was then used to locate a third monitoring well. Although gasoline is a mixture of over 200 petroleum-derived chemicals, analysis of the gasoline components is usually limited to the detection of Benzene, Toluene, Xylene and Total Volatile Hydrocarbons (TVH). Those constituents possessing high vapor pressures, low molecular weights, and low aqueous solubilities readily partition out of the groundwater and into the soil-gas zone enabling detection by portable monitoring equipment. The procedure for collecting the data involved using the auger equipment described in section 2.0 above, sampling at depths of 9~ 14, and 16 feet using the 'split spoon sampler. The bottom of the acquired brass tube was covered with sterilized gauze allowing air to flow through the tube. TVH in parts per million (ppm) was 'then measured using the TIP photoionization detection meter to extract and analyze the vapors. Additionally, an auger hole was drilled and sampled upgradient and outside of the contaminated area to determine what the ambient readings would be on clean soil at the facility site. This data will serve as a guide to determine the plume's boundry. A summary of data collected from each auger hole location is presented in Plate 4. A contour map showing TVH (Plate details the readings observed at 14 and 16 feet for the auger hole locations. Based on this information, it was decided to locate the third monitoring well between auger holes A-9 and A- 10. 4.0 FINDINGS 4-. ! Laboratory analysis of Soil Samples Soil samples taken from boreholes B-l, B-2, and B-3 were anlayzed by B.C. Laboratories of Bakersfield, California, using EPA RESOURCE INDUSTRIES Golden Empire Transit 5020/8020 method to determine BTX-TF'H concentration of constituents present. gasol i ne The analyses on soil samples from boring _B-,~ indicate belc~ action level contamination for soil down to 25 +eet--a~o non- detectable amounts at 29 feet. The concentration levels for Total Petroleum Hydrocarbons (TPH) ranged in value from 174 ppm at 16-~eet to 56 ppm at 20 feet to 148 ppm at 25 feet. Boring B-2, located by the dispenser, had non-detectable amouot~ of contamination from 5 feet down to the total depth of ~0' feet~ Soil samples analyzed for boring B-3 also revealed non-detectable amounts of contamination within the soil. Laboratory results in Appendix A. 4.2 Laboratory Analysis of Water Samples Twenty-.fc)ur hours after completing the monitoring wells, the water was sampled using a teflon bailer. Four well volumes were purged from each well to ensure a representative sample was taken from the aq ~' ~ . u~er Two water samples taken from each well and a travel blank were sent to B.C. Laboratories to be analyzed, for TX-TPH using EPA 602 method. Groundwater samples from ~ (~orino B-l) revealed a high~ concentration of 5.10 parts~r billion (ppb) and 9.56 ppb for Benzene from the two samples. Toluene concentrations were 7 ppb to 5:6 ppb, respectively and the total Xylenes were 2502 ppb to 2].6.~ ppb~ respectively. Groundwater samples from MW-2 (Boring B-2) showed no reportable levels of contamination from either sample. One of the water samples from ~ (Boring B-5), collected ---Se,- .p'-ember_ 5~0, 1987, reported 1.6 ppb Benzene and 1.6 ppb TPH, ~.while anaiytes in the second sample were all below minimum reporting level. The B.C. Laboratories analyst who ran those samples explained the difference between the two 5 ml sample runs as a possible interference due to a trace amount of Benzene in the lab equipment (see letter, Appendix C). MW-3 was resampled and ~ ml samples were analyzed to avoid interference due to pc)ssible hydrocarb6n residuals in the lab equipment. ~oundwate~ samples from MW-~ showed no reportable levels of The travel blanks, analyzed for the same constituents as the water samples, indicated no detectable levels of contamination. 4 GRO DWATER RESOURCE INDUSTRIES Golden Empire Transit 4.5 Geology and Hydrogeology The project site is located on the west-side of the San Joaquin Valley bordering the Sierra Nevada Mountains. Surface geology at this location consists of Sierra Nevada provenance alluvial fan materiai. These Pleistocene continental deposits were derived from the erosion of hard crystalline granitic rocks by the Kern River- and laid down as coalescing alluvial fans. The Kern River Alluvial fan lies along the river between Bakersfield and Oildale and radiates out into the valley in a lid-degree arced fan sloping approximately 7 feet per mile. 'The sediments penetrated by the borings are comprised of loosely compacted silts to 10 feet and poorly sorted sands, commonly containing pebbles and cobbles, to 35 feet. The silts were brown to grey in coloring with occassional rust colored mottling and were only slightly plastic. The sands were grey and brown in color, micaeous, and silty with low plasticity and contained layers of one-inch pebbles and cobbles. Kern County Water Agency' (KCWA) reported depth to unconfined groundwater in 1986 (most recent report) to be less than 5A feet belc>w ground level at this site. During the drilling process groundwater wa~ mncountered at approximately. 16.feet below in borings B-1, B-2 and B-5. The Kern River,located approximately one-half mile to the northwest, serves as the primary natural and artifical recharge to the groundwater basin. According to the KCWA, the direction o~ groundwater movement away Yrom the Kern River in a southeasterly direction with a gradient of approximately 75 feet per mile. The results from G.R.I. 's soil-gas investiqation would suggest a south to · ~utheasterl~ ~1~ direction ba~ on the direction' o~ the conL~mina~ion plume within the groundwater. The average rainfall in the vicinity of the site, based on a 20 year- average, is estimated at 5.5 inches. As measured at the Bakersfield Airport, located 2.25 miles to the northwest, 50 percent of the average precipitation occurs in the winter (January, February, March) and only 2.percent during the summer (July, August, September). 5. ¢} CONCLUSIONS REGARDING THE CONTAMINATION F'LUME 5.1 Vadose Zone F'lume The location of the contamination release was found to be in the 5 GROUNDWATER RESOURCE INDUSTRIES Golden Empire Transit a~ma~of-the Red Jacket line leak detector on the 10,000 unleaded gasoline tank. The tank rested on a concrete slab approximately two feet thick. Pea-gravel was used as a fill above the concrete slab and surrounding the tank. Below the concrete slab ~ was undisturbed soil. Plate 5 shows a cross section of the plume in the vadose zone. Due to the high permeability of the pea-gravel and the lack of undisturbed soil between the tank and groundwater, liquid contamination Would percolate downward with little lateral extent. The soil from the four-foot deep excavation around the turbine pump contains contamination from the spill and is presently covered,on-site, with polyethlyene sheeting. 5.~ ~ Groundwater F'lume As discussed in section 5.1 above, contamination from the release quickly migrated through the fill into the groundwater. L~boratory analysis of groundwater from borings. B-2.-¢~W--~) a~d., 8-3 (MW-3), however, indicated non-detectable levels-' of contamination present. The location of MW-2 is believed to~ be dust outside the direction of groundwater flow downgradient from MW-1. MW-~. located ~proximatel¥ 59 feet south-southeast of MW- 1 i~ believed to be in the heart of the suspected plume based on t~e da~a collected from the sol'l-gas investigation (see Plate 5). The rate of groundwater flow has not. been determined nor is it available in the source literature due to seasonal variations and other variables such as recharge and discharge rates and the fact that the Kern River is a controlled flood channel. It is important to note however that 1986-87 was a dry season and that flow from the Kern River is slow throughout the summer months. Based on the laboratory anai~ses, the soil-gas investigation, and the hydrogeological data available it appears as if the groundwater plume migrated south-southeast with some of the volatiles partitioning out into the soil-gas zone. Those volatiles that don't readily partition out are more water soluable and have lower vapor pressures. It has been found that soils predominantly contaminated by migrating vapors, rather than liquids, will show higher field values than laboratory values because the photoibnization detector extracts vapors from a large volume of relatively undisturbed soil within the brass core-tube, ~hile the lab analyst takes only one or two grams of sub-sample 6 GROL DWATER RESOURCE INDUSTRIES Golden Empire Transit and aerates it in the process of handling it. This was confirmed by the soil-gas investigation which essentially defined the pathway of the plume even though groundwater contamination is no longer detectable downgradient from the release. 5.5 Near-Term Threat Due .to Plume in Vadose Zone The source of contamination (i.e. the area of the Red Jacket line leak: detector) is located in the middle of the bus parking lot at the prodect site which is sealed by asphalt and concrete paving. The near-term threat to biological receptors is minimal due to the remote and secured location of the contamination and because a large part of the contaminated soil has. been removed during the repair operations on the leaking pipe-union. Several factors needed to be addressed because there still exists the potential for near-term problems. The presence of buried pipes and structures in the immediate area might serve as conduits for migrating vapors which in turn might collect beneath the paving in an explosive concentration. A wash rack for the buses is located approximentely seventy feet northeast of the source of contamination. This, combined with precipitation, could flush any remaining contamination down into the groundwater. Finally, there'is also the possibility of water- level flucuations as' a result of the Kern River rising and falling. This could effectively wash contaminants from the base of the vadose plume into the groundwater. 5.4 Near-Term Threat Due to Plume in Groundwater As previously discussed, the amount of gasoline released into the. soil is small. The soil-gas investigation revealed the direction of the groundwater plume by tracking the remnant vapor concentrations that partitioned out into the soil-gas zone above the water table. Subsequent borings showed that the groundwater plume is no longer detectable at MW-3, indicating that the plume has dispersed into very low concentration levels. The cost associated with assessing the extent of the plume outside the Golden Empire Transit District facility versus the threat imposed by it would be inordinant because the threat is minimal. _ / /Many of the same concerns discussed under Section 5.~ would apply ~ to the groundwater, since any contamination in the vadose zone can groundwater zone should leaching occur. Therefore, it affect the is the opinion of G.R.I. that remediation be directed at removing the contaminated soil in the vadose zone followed by a water' analysis to determine if the plume still exists at MW-1. 7 Golden Empire Transit 5.5 Long Term Effects '[he long term threat of the vadose and groundwater plumes to biological receptors would be minimal under existing conditions. However, should the facility be altered or put to some other use that might uncover the contamination in the process, the risk of exposure to bioreceptors (people) would increase. 6.0 6.1 REMED I AT I ON ALTERNAT IVES Limited ' Excavation Limited excavation is considered to be the quickest and most economical method of remediation. The pea-gravel beneath the Red Jacket line leak detector should be removed as well as any soil beneath the tank down to the groundwater table. On-site monitoring with a photoionization meter should be used to determine when ali of the contamination has been removed. All excavated soil, including the contamination contained within the soil presently stored at the surface, should be manifested and disposed of at an appropriate site. Clean backfill should be used to restore the excavation to grade.~,~'~ .~ Vapor Extraction The second most favorable form of remediation would be to use the existing monitoring well as an extraction well whereby the volatiles are extracted and filtered using activated carbon drums. Operations would cease when extracted gases meet the concentration levels set by the county. The time required to achieve an acceptably low level of contamination may be as little as a few weeks to a few months. 6.3 ~~ ~ The "no- rnative would allow the diffusion and natural degradation to destroy the plume over a very long period of time.

Lab. No's 20425, 20426, 20924-1 GRI Project No. 06187 Gentlemen, This letter is to confirm my telephone and in-person conversations with Terry Rowles on October 15, 1987. As per my understanding BC Laboratories was ex- periencing background contamination of benzene prior to the analysis of water samples (MW3-1 and MW03-1 collected September 30, 1987) from project number 06187. You explained that a 5 ml quanity of sample is analyzed and that the background levels of benzene in this small of quanity could show up as being slightly above the minimum reporting level. To resolve this conflict you sug- gested analyzing a larger quanity (25 ml). You also indicated at this time that these additional samples would be processed free of charge. Based on this information, G.R.I. obtained two (2) water samples and had them analyzed on October 15, 1987. Sample identification information is as follows: Samples- MW3-1, MW3-2, Travel blank Lab.

TEST BORING PROCEDURES I. Soil Sampling Protocol The following procedures are followed during soil sampling operations utilizing the hollow stem auger drilling technique· A. Hollow Stem Auger Soil borings drilled by the hollow stem auger utilize continuous flight hollow stem augers. Augers, samplers-and all downhole equipment are steam cleaned prior to use. In the field steam cleaning is done between borings to minimize the potential for cross-contamination. A G.R.I. geologist observes the work, visually logs the soils, and collects.samples at appropriate intervals. The Unified Soils Classification System is utilized to classify soils encountered· Additional geologic observations'are noted as appropriate. Soil samples destined for laboratory analysis are collected by a modified California Split Spoon. This sampler uses three,, six inch long, by two inch diameter (o.d.) tubes· Various tubes can be utilized to accommodate the type of analysis necessary:. B=aSS Stainless Steel Plastic Ail organics and general analyses (not to be used for copper or zinc analysis). Ali organics and metals analyses for copper and zinc (not to be used for chrome or nickel analyses) All metals analyses (not to be used for organics) RESOURCE INDUSTRIES · II HONZ~ORZNG HELL. ,%AMPLXNG PROTOCOL Decontamination The following procedure details, the routine that is employed in decontamination of groundwater Sam. piing equipment prior to sample collectiont 1. Exterior surface of sampling, tubes are decontaminated by steam-cleaning during withdrawal fromeverywell. Sample pump is disassembled and the usbd bladder removed. All pump components are then steam-cleaned and rinsed in distilled water, Pump is reassembled with a new bladder installed. Teflon sampler* lines are pressure washed with 5 to 10 gallons of clean, hot water through direct connection to .ateam-c~eaner. ' Five gallons Of distilled water are then'~umped through' entire system. Prior to sample.~ollection, a minimum of five well volumes are purged from the well to permit collection of a ripreaentative groundwater sample .from the aquifer penetrated. Purge Volume. Determination .. The following procedure la followed to determine the appropriate purging volume prior to well sampling.' 1. The depth~to-water is measured by a clean, electric water level indicator. Measurement datum is the top of fill' ring or .top of well protector, 2. Depth to t~ bottom of the well is'measured by'a clean tape and plump bob.' If poaalble,.thla is compared to well.construction log to. determine inconsistencies, i.e. .damaged casing, sediment 'in ca~ing, etc. [. RESOURCE iI IDUSrRiE$ Append~ '0 (cost "d) The tubes are cleaned and prepared in the G.R.I. laboratory. Tubes are scrubbed, inside and outside, with a brush and TSP. They are next steam cleaned, and packed in clean containers with seals. Tubes are delivered to the drilling site in these closed containers to preserve the state of cleanliness. .. After the sample(S) have been removed from the sampler, the sampler is completely disassembled and scrubbed in TSP and tap water. It is then rinsed in two separate tapwater baths and assembled with three, clean tubes. Dirty tubes are field washed.in TSP, rinsed with water, and placed in buckets for transport back to the G.R.I. lab for cleaning and preparation. 9. The sampler is driven by a 140 pound hammer with a 30 inch free fall. Blow counts are recorded as number of blows per 6 inches-of drive. 10. The sampler is driven 18 inches at each sampling interval. The first (or lowest.) tube is generally retained as the sample for analysis. The other two tubes are retained for. back-up or split samples. 11. 12. 13. A sand catcher'is used in the sampler where loose soils are anticipated. This'will prevent the soil from falling out of the sampler. After retrieval, the sample is.visually logged and immediately sealed with. aluminum foil .lined caps, labeled, and chilled. Clean field ice chests and chemical ice ("blue ice") are used to keep the samples cold until delivered to the chemical laboratory. Teflon seals are a~so available for field samples. .~ Samples are delivered'to, the laboratory the same day they are taken, if physically possible. If the samples must be held until the next day, they~ are kept frozen in a secure' freezer at the G.R.I. facility. Sample control is maintained by a Chain of Custody form which accompanies the sample. The form documents the time, date, and responsible person during each step in the transportation process.
