The purpose of this investigation was to evaluate the presence of petroleum hydrocarbons in soil and ground water, to calculate the ground-water direction of flow and gradient, and to provide recommendations based on evaluation of the collected data. During this investigation, three 4-inch diameter monitoring wells, MW-1 (boring Bo7), MW-2 (boring B-8), and MW-3 (boring B-9) were installed at the Site. Soil samples were obtained at S foot intervals from each of the three monitoring well borings. F..ach sample was field analyzed for petroleum hydrocarbons using a photoionization detector (PID). No petroleum range hydrocarbons were detected.. in samples collected from the MW-2 (B-S) and MW-3 (B-9) borings. Petroleum hydrocarbons were detected in one sgil sample obtained from a depth of 30 feet in the MW-1 (B-7) boring. Sample S-SO- B7 contained benzene and TPHg concentrations at 0.04 ppm and $1 ppm, respectively. Four soil samples from each monitoring well boring were submitted to a State certified laboratory for analysis of selected gasoline constituents. After installation of the three monitoring wells, the wells were developed, purged, and sampled for laboratory analysis.

The Site occupies a portion of the south half of the northwest quarter of Section 19, Township 29 South, Range 28 East, Mount Diablo Base and Meridian. Elevation at the Site is approximately 408 feet above sea level (the National Geodetic Vertical Datum of 1929). The Site location is shown on the Vicinity Map presented as Plate 1. 2.2 Site Description The Site consists of a mini market, two fuel dispenser islands beneath a canopy, asphaltic concrete paved traffic and park~n§ areas, and three underground gasoline storage tanks. The property is bound by 34th Street along the south, Sewett Avenue along the east, a residence to the north,.and a vacant undeveloped parcel to the west. The locations of the Site facilities are shown on the Site Plan presented as Plate 2. 2.3 ReRionai Geology The Site, within the City of Bakersfield, is located in the southern San Joaquin Valley, a northwest trending structural trough bound on the east by the Sierra Nevada, on the south by the Tehachapi Range, and on the west by the Coast Ranges. Bakersfield is underlain by Quaternary alluvial material deposited by the southwest flowing Kern River. The alluvium is principally derived from granitic sources in the east adjacent Sierra. Tertiary. sediments of marine origin underlie the Quaternary section. These are underlain in turn by crystalline basement rocks similar in composition to the Sierra. 2.4 ReRionai Hvdrogeolo~v Ground water occurs in unconfined conditions beneath the Site at an elevation of approximately 250 feet above mean sea level, or aDproximately 158 feet below surface. The direction of ground~water flow, based on the 1990 Kern County Water Agency Water Supply Report, is toward the so~t, away from the Kern River which is located northwest of the subject Site.

ASSESSMENT OF THE LATERAL EXTENT OF PETROLEUM HYROCARBON AFFECTED SOIL AND GROUND WATER FORMER BEACON STATION NUMBER 571 1102 34TH STREET BAKERSFIELD, CALIFORNIA 1.O INTRODUCTION SSB Environmental Consultants, Inc., conducted an assessment of soil and ground-water quality at Former Beacon Station Number 571 (Site), located at 1102 34th Street in Bakersfield, California. The investigation was undertaken at the request of Ultramar Inc. (Ultramar). 1.1 p,urpose The investigation was ~lesigned to evaluate the lateral extent of gasoline range hydrocarbons in soil; to explore the possibility of a perched water zone beneath the Site; to determine the ground-water direction of flow and gradient of the perched water, if encountered; and to provide recommendations based on evaluation of the collected data. 1.2 Scope of Work During this investigation, three 4-inch diameter monitoring wells, MW-1 (boring B-7), MW-2 (boring B-8), and MW-3 (boring B-9), were installed at the Site. Prior to installing the monitoring wells, soil borings were drilled and soil samples were obtained from each boring at 5 foot intervals. Each soil sample was field analyzed for the presence of gasoline range hydrocarbons using 'a photoionization detector (Model OVM 580B). Field analysis readings are recorded on the boring logs in Appendix A. Four soil samples from each boring were submitted for laboratory analysis for benzene, toluene, ethylbenzene, xylenes (BTEX), and total petroleum hydrocarbons using a gasoline standard (TPHg). After each boring was drilled to approximately 45 feet below surface, a 4-inch diameter monitoring well was installed. Each well was constructed with 15 feet of screened pipe, with approximately 10 feet of screened interval below the existing ground-water table. Each monitoring well was developed and purged. Samples were collected from each well for analysis for BTEX and TPHg. After surveying each well head, the ground-water gradient and flow direction were evaluated using depth-to-ground-water measurements collected in June, 1992. Former Beacon Station Number 571 SSB 90-1091-03 1102 34th Street Page 3 Bakersfield, California during the Pleistocene and Holocene which divide thc Quaternary section into confined and unconfined aquifers do not occur below thc Site. Based on information provided by California Water Service Company, there are two municipal water supply wells located within one-half mile of the site. Both wells are owned by the California Water Service Company. Depth to static ground-water levels from both wells taken in October, 1990, yielded a depth of 162 feet in the well located at 32nd Street and Claflin Avenue, identified as Station 118 (approximately 750 feet southeast of the site), and a depth of 190 feet in the well located at 33rd Street and San Dimas Avenue, identified as Station 33 (approximately 1,750 feet east of the site). The well at Station 118 is active and pumps at an average rate of 886 gallons per minute. The well at Station 33 is active and pumps at an average rate of 560 gallons per minute. The location of the above-mentioned wells are presented on Plate 3. 2.$ Project History On November 30, 1989, during the installation of overfill protection equipment on the underground storage tanks, soil samples were collected from the tank backfill material and analyzed for the presence of petroleum hydrocarbons. The analytical results indicate the presence of hydrocarbons in the backfill material. Subsequent investigations conducted by Evax Technologies, Inc. involved a soil gas survey and a subsurface soil investigation. The results of the soil gas survey were used to direct the subsurface soil investigation. Three borings were drilled during the course of the soil investigation. Two soil samples collected from each boring were submitted for laboratory analysis. The sample collected from boring B-l, from a depth of approximately 24.5 feet, contained 0.64 rog/kg TPHg. No other analyzed compounds were detected in any of the soil samples. A saturated zone was encountered in borings B-1 and B-2 at approximately 30 feet below surface. Water samples collected through each boring were analyzed for petroleum hydrocarbons. Gasoline fuel constituents were detected in both analyzed Water samples. The results of the soil and ground-water samples are presented in Table 1. These investigations were conducted in March of 1990, the results are presented in a report dated April, 1990. In October of 1990, two borings were drilled at the Site. Boring B-5 was drilled near the southwest corner of the property and boring B-6 was drilled along the north property line, north of the underground storage tanks. Soil samples were obtained at 5 foot intervals from each boring. The soil types encountered consist of fine to medium grained silty sands in the upper 8 to 11 feet.

Auger refusal occurred at depths of approximately 31 feet in boring B-5 and approximately 28 feet in boring B-6 due to the presence of gravels and possibly cobbles. The perched ground-water zone encountered by Evax Technologies, Inc. in their - March, 1990, investigation was not encountered in either boring drilled on October 9, 1990. Soil samples collected during October 9, 1990, drilling from depths of 20 and 25 feet from both borings were submitted to a State certified laboratory and analyzed for concentrations of benzene, toluene, ethylbenzene, xylenes, and total petroleum hydrocarbons as gasoline. Toluene, xylenes, and total petroleum hydrocarbons as gasoline were detected in the soil sample collected from a depth of 25 feet from boring B-$. No hydrocarbon constituents were detected in the other analyzed samples. These results arc also included in Table 1. SSB ENVIRONMENTAL CONSULTANTS, INC.

Former Beacon Station Number 571 SSB 90-1091-03 1102 34th Street Page 10 Bakersfield, California 4.0 EVALUATION The following sections present our evaluation of the findings of field and laboratory investigations. 4.1 Gasoline, Range Hydrocarbons in Soil Gasoline range hydrocarbons were detecteA only in one sample (S-30-B7), in boring B-7 (MW-l), located near the location of Evax Technologies, Inc. boring B-l, which also contained low levels of TPHg at 24 feet in sample S-B1-24.5. The 35 foot sample from B-7 did not contain any analyzed gasoline range hydrocarbons. However, the sample was collected below the stabilized water level in MW-1 constructed in B-7. 4.2 Ground-Water Quality Gasoline range hydrocarbons were detected in water samples obtained from monitoring wells MW-1 and MW-2. Monitoring well MW-1 contained the highest concentration of gasoline range hydrocarbons (TPHg = 390 ug/1). Water samples collected from the downgradient monitoring well (MW-3) contained no detectable levels of analyzed hydrocarbons. $.0 CONCLUSIONS On the basis of our findings, we present the following conclusions: 1) The soil profile at the Site consists of silty, fine to medium grained sand to a depth of approximately 10 feet, underlain by interbedded, well graded sands and gravels. Cobbles were encountered at a depth of 30 feet. Ground water was encountered in each boring at approximately 35 feet. 2) Petroleum hydrocarbons were detected in only one soil sample collected during the recent investigation. Sample S-30-B7 contained benzene and TPHg concentrations at 0.04 rog/kg and 51 mgjkg, respectively. TEX values were detected at trace concentrations. No petroleum hydrocarbons were detected in soil samples collected from the MW-2 (B-8) and MW-3 (B-9) borings. SSB ENVIRONMENTAL CONSULTANTS, INC. Former Beacon Station Number 571 5SB 90-1091-03 1102 34th Street Page 11 Bakersfield, California 3) A perched water zone was encountered. The flow direction for the perched zone is south by southeast with a gradient of approximately 0.061. The depth to perched water after monitoring well installation ranged from 32.97 feet in MW-2 to 37.06 feet in MW-3. 4) Petroleum range hydrocarbons were detected by laboratory analyses in the ground-water samples collected from MW-! and MW-2. No measurable concentrations were detected in the water collected from the down-gradient well MW-3. 6.0 RECOMMENDATIONS On the basis of our findings, we present the following recommendations: 1) We recommend that the depth to ground water in the three monitoring wells at the Site be measured periodically, and that ground-water samples be obtained for analysis quarterly until sufficient data is collected to determine if additional work at the Site is necessary. 2) A copy of this report should be forwarded to Mr. Joe Canas at the Kern County Environmental Health Department and to Mr. John Noonan at the CVRWQCB at the following addresses.

If subsurface conditions different from those encountered during our explorations are observed or appear to be present, we must be advised promptly so that we can review those conditions and reconsider our conclusions where necessary. If there is a substantial lapse of time between the submission of our report and the start of additional work at the Site, or if conditions have changed due to natural causes at or adjacent to the Site, we urge that our report be reviewed to determine the applicability of the conclusions considering the changed conditions and time lapse.

The ends of each sample sleeve retained for analysis were covered with teflon, capped with plastic end caps, sealed with adhesiveless tape, and labeled with pertinent information such as sample number, date and time collected, sample location, and sampler. Each sample was immediately placed in an ice chest and cooled to 4°C using blue ice. Monitoring Well Installation Procedures The monitoring well consists of 4 inch diameter Schedule 40 PVC casing set in an 10-inch diameter boring. The boring was drilled under the direction of an engineer or geologist from our firm. A detailed boring log was kept at all times noting: 1) material types encountered with depth (Unified Soils Classification System),' and 2) moisture conditions. The boring was drilled using a Mobile B-57 drill rig equipped with 10-inch diameter continuous flight hollow stem augers. The monitoring wells consist of a bottom plug followed by 20 feet of Schedule 40 PVC' screen with factory machined horizontal slots (0.020 inches), then blank casing to the surface. Each section of casing is ioined together using factory- made threaded connections, thereby eliminating the necessity for any glues or solvents. The well packing material consists of pre-washed medium grained sand and extends a minimum of 2 feet above the slotted casing. Bentonite tablets were used to seal the well casing. A neat cement slurry was used to backfill the remainder of the boring. A locking cap was set on top of the well head which is set approximately 0.5 feet below grade. A flush mounted water tight box was used to protect the well head. Ground-Water Samplint Methods A ground-water sample was collected from each monitoring well. Prior to sampling thc well, approximately three to five well volumes were removed in order to bring fresh formation water into the well. The ground-water sample was collected using an individually wrapped disposable teflon bailer. Thc ground-water sample was placed in the appropriate glass containers with teflon-lined lids. Each sample was labelled and immediately placed in an ice chest and cooled to 4°C using blue ice. Sample Shipment and Chain-of-Custody Procedures Complete records were kept on each sample including sampling date, sample type, location, and other pertinent information. The sample containers were banded and sealed with chain-of-custody seals. The samples were cooled to 4°C at the site and maintained at that temperature until delivered to a State certified laboratory. Chain-of-custody procedures, generally described in Test Methods for Evaluating Solid Waste, SW-846, U.S. EPA, Second Edition, were followed. A chain-of-custody form accompanied the samples from the place of collection to the testing laboratory, and through the completion of the analytical process. The chain-of-custody form included project identification information, the sample type and number, the date and time of sampling, the chemical analyses requested, and the identity of the person taking possession at each change of custody.

The proposed work includes: 1) drilling two soil borings through a cobble layer encountered beneath the site; 2) collecting soil samples at $ foot intervals for field evaluation and laboratory analysis; 3) analyzing selected soil samples obtained from the borings for gasoline constituents benzene, toluene, ethylbenzene, total xylenes (BTEX), and total petroleum hydrocarbons as gasoline (TPHg); 4) drilling a third boring and constructing ground-water monitoring wells through each boring if ground water is encountered; and $) preparing a Preliminary Report (PR) documenting field methodologies and presenting findings, conclusions, and recommendations. The proposed work will be performed by SSB Environmental Consultants, Inc. (SSB), under the supervision of a registered engineer. 2.0 BACKGROUND INFORMATION Pertinent information required to obtain an understanding of the project is presented in the following sections. 2.1 Site Location The site is located at thc northwest corner of the intersection of 5ewett Avenue and 34th Street in Bakersfield, California. The site occupies a portion of the south half of the northwest quarter of Section 19, Township 29 South, Range 28 East, Mount Diablo Base and Meridian. Elevation at the site is approximately 408 feet above sea level (the National Geodetic Vertical Datum of 1929). The site location is shown on the Site Vicinity Map (Plate 1). Former Beacon Station No. 5'/1 SSB 90-1091-02 110~ 34th Street Page Bakersfield, California 2.2 Site Description The site consists of a mini market, two fuel dispenser islands beneath a canopy, asphaltic concrete paved traffic and parking areas, and three underground gasoline storage tanks. The property is bound by $4th Street along the south, .lewett Avenue along the east, a residence to the north, and a vacant undeveloped parcel to the west. The locations of the site facilities are shown on the Site Plan (Plate 2). 2.3 Regional Geolonv The site, within the City of Bakersfield, is located in the southern San $oaquin Valley, a northwest trending structural trough bound on the east by the Sierra Nevada, on the south by the Tehachapi Range, and on the west by the Coast Ranges. Bakersfield is underlain by Quaternary alluvial material deposited by the southwest flowing Kern River. The alluvium is principally derived from granitic sources in the east adjacent Sierra. Tertiary sediments of marine origin underlie the Quaternary section. These are underlain in turn by crystalline basement rocks similar in composition to the Sierra. 2.4 Regional Hydrogeolo~v Ground water occurs in unconfined conditions beneath the site at an elevation of approximately 250 feet above mean sea level, or approximately 158 feet below surface. The direction of ground-water flow, based on the 1990 Kern County Water Agency Water Supply Report, is toward the southeast, away from the Kern River which is located northwest of the subject site. Regional clay and silt strata deposited during the Pleistocene and Holocene which divide the Quaternary section into confined and unconfined aquifers do not occur below the site. 2.5 Project History On November 30, 1989, during the installation of overfill protection equipment on the underground storage tanks, soil samples were collected from the tank backfill material and analyzed for the presence of petroleum hydrocarbons. The analytical results indicate the presence of hydrocarbons in the backfill material. Subsequent investigations conducted by Evax Technologies, Inc. involved a soil gas survey and a subsurface soil investigation. The results of the soil gas survey were used SSB ENVIRONMENTAL CONSULTANTS, INC. Former Beacon Station No. $71 SSB 90-1091-02 1102 34th Street Pa$¢ 3 Bakersfield, California to direct thc subsurface soil investigation. Three borings were drilled during the course of thc soil investigation. Two soil samples collected from each boring wcrc submitted for laboratory analysis. The sample collected from boring 1, from a depth of approximately 24.$ feet, contained 0.64 parts per million TPH gas. No other analyzed compounds were detected in any of the soil samples. A saturated zone was encountered in borings 1 and 2 at approximately 30 feet below surface. Water samples collected through each boring were analyzed for petroleum hydrocarbons. Gasoline fuel constituents were detected in both analyzed water samples. The results of thc soil and ground-water samples are presented in Table 1. These investigations were conducted in March of 1990, the results are presented in a report dated April, 1990. In October of 1990, two borings were drilled at the site. Boring B-$ was drilled near the southwest corner of the property and boring B-6 was drilled along the north property line, north of the underground storage tanks. Soil samples were obtained at $ foot intervals from each boring. The soil types encountered consist of fine to medium grained silty sands in the upper 8 to 11 feet. These soils were underlain by fine to coarse grained poorly graded sands with well-rounded gravels to the maximum depth explored, approximately 31 feet below surface. Auger refusal occurred at depths of approximately 31 feet in boring B-5 and approximately 28 feet in boring B-6 due to the presence of gravels and possibly cobbles. The ground water encountered by Evax Technologies, Inc. in their March, 1990, investigation was not encountered in either boring drilled on October 9, 1990. Soil samples collected during October 9, 1990, drilling from depths of 20 and 25 feet from both borings were submitted to a State certified laboratory and analyzed for concentrations of benzene, toluene, ethylbcnzene, xylenes, and total petroleum hydrocarbons as gasoline. Toluene, xylenes, and total petroleum hydrocarbons as gasoline were detected in thc soil sample collected from a depth of 25 feet from boring B-$. No hydrocarbon constituents were detected in the other analyzed samples. These results are also included in Table 1. SSB ENVIRONMENTAL CONSULTANTS, INC.

Former Beacon Station No. 571 SSB 90-1091-02 110l 34th Street Page 5 Bakersfield, California 3.0 DISCUSSION The vertical extent of hydrocarbon affected soil has not been determined by the previous investigations. The first investigation (conducted by Evax Technologies, Inc.) was limited to first encountered ground water, which was not observed in the subsequent investigation (conducted by SSB). The SSB investigation was limited by auger refusal from encountered gravels and possibly cobbles. Our proposed work includes using a casing hammer or similar type drill rig that will penetrate the gravel/cobble layer and allow for collection of soil samples at roughly $ foot intervals. Initially, two borings will be drilled, one near boring B-$ and the other near boring B-6, to establish the vertical extent of hydrocarbon affected soil. If ground water is encountered in the first boring before the vertical extent of affected soil has been determined, then a third boring will be drilled near the southeast corner of the property and monitoring wells will be constructed through each boring. Thc proposed boring and possible well locations are shown on Plate 2. 4.0 PROPOSED WORK The proposed work is recommended to establish the vertical extent of hydrocarbon constituents in soil and possibly ground water at the site. The following tasks will be performed by SSB. 1) Prepare a Site Safety Plan discussing the precautions and protective equipment required for work at the site. 2) Acquire all necessary permits from the appropriate regulatory agencies to conduct the investigation. 3) Drill two soil borings using a casing hammer type drill rig near the locations of borings B-5 and B-6. Drill a third boring near the southeast property corner if ground water is encountered in the first boring and construct ground-water monitoring wells through each boring. SSB ENVIRONMENTAL CONSULTANTS, INC. Former Beacon Station No. 5'/1 SSB 90-1091-02 1102 34th Street Page 6 Bakersfield, California 4) Collect and classify relatively undisturbed soil samples from the unsaturated zone in each boring at 5 foot intervals beginning at 5 feet below ground surface. A photoionization detector (PID) or similar device will be used in the field to subjectively evaluate the relative concentration of hydrocarbons in the soil samples. Once the gravel/cobble layer is encountered, soil samples will not be collected until the layer is penetrated. 5) Submit an estimated minimum of four soil samples per boring for laboratory analysis (two samples associated with the highest PID readings and the bottom two 5-foot samples either directly above the saturated zone or with no field indications of hydrocarbons). The samples will be analyzed for the hydrocarbon constituents BTEX and TPHg. I~~ If ground water is encountered, construct one 4-inch diameter PVC cased ground-water monitoring well in each boring. Develop each well for sampling. 7) Collect ground-water samples from each monitoring well for analysis of BTEX and TPHg. Ground water purged from the monitoring wells will be stored on-site in $5 gallon drums. The removal or treatment of this material will be directed by Ultramar. Conduct a level survey of the monitoring wells to determine well head elevation relative to sea level.' The ground-water gradient and flow direction will be evaluated. 9) Prepare a PR summarizing field and laboratory procedures, findings, interpretations, conclusions, and recommendations. 4.1 Site Safety Plan Field work performed by SSB at the site will be conducted in accordance with a Site Safety Plan. This safety plan will describe the basic safety requirements for the subsurface environmental investigation and drilling soil borings at the site. The Site Safety Plan is applicable to personnel and subcontractors of the consultant. The consultant's personnel and subcontractors personnel scheduled to perform work at the site will be briefed on the contents of the Site Safety Plan before work begins. A copy of the Site Safety Plan will be kept at the site and will be available for reference by appropriate parties during work at the site. A Site Safety Officer will be appointed for the duration of the subject work at the site. $SB ENVIRONMENTAL CONSULTANTS, INC.

Underground Service Alert will be contacted prior to drilling to delineate public utility lines. Initially, the boreholes will _ be hand-augered to a minimum depth of $ feet. The soil borings will be drilled using a casing hammer type drill rig with 9- or 10-inch O.D. casing. The casing and drill equipment will be steam-cleaned prior to each use to minimize the possibility of cross-contamination between borings. The soil sampling equipment will be cleaned with an Alconox or TSP solution prior to each sampling event to prevent the possibility of cross contamination. Drilling will be performed under the guidance of a field geologist or engineer, and the earth materials encountered in the borings will be logged as drilled. Soil samples will be logged using the Unified Soil Classification System and recorded onto a boring log form. During drilling, soil samples from the borings will be collected at $ foot intervals by driving or pushing a thin walled steel sampler equipped with clean 2-inch O.D. brass sleeves using the protocols described in Appendix A. Each boring will be drilled until two consecutive $ foot sampling intervals show no field indications of hydrocarbons or when ground water is encountered. The maximum depth will be 15 feet below first encountered ground water. The wells will be constructed using the protocols described in the appendix. Auger cuttings from the borings will be stockpiled on-site on plastic sheeting. Removal or disposal of the cuttings will be directed by Ultramar. 4.3 Laboratory Analysis An estimated minimum of four soil samples from each borehole will be selected for laboratory analysis. The selected samples will be analyzed in the laboratory for BTEX, using EPA approved methods; and TPHg by modified LUFT Guideline methodologies. Detection limits suitable for the soil tests requested and concentrations present will be stated On the laboratory reports. Copies of the laboratory reports will be included in our final report.

Suite 103. Fresno, CA 93727 (209) 292-5736 EXECUTIVE SUMMARY SSB Environmental Consultants, Inc., was authorized by Ultramar Inc. (Ultramar) to conduct an investigation of soil and ground-water conditions beneath former Beacon Station Number 571 located at 1102 34th Street in Bakersfield, California. The purpose of this investigation was to evaluate the presence of hydrocarbon constituents in soil and ground water beneath the site and to provide recommendations based on evaluation of the collected data. The work attempted was that outlined in Ultramar Work Plan dated June 19, 1990, which included drilling three soil borings, collecting and analyzing soil samples, then constructing ground-water monitoring wells in each boring to obtain ground-water samples for analysis. The work followed a soil vapor study and soil investigation conducted by Evax Technologies Inc. in March of 1990. In their investigation, four borings were drilled and soil samples were collected for laboratory analysis. A soil sample collected from a depth of 24.5 feet from boring B-1 was the only analyzed soil sample that contained detectable petroleum hydrocarbons. Petroleum hydrocarbons were detected in ground-water samples collected through the auger in borings B-1 and B-2 from a depth of approximately 30 feet below surface. During this investigation, o.n? ~two of the three proposed borings were drilled at the site. Boring B-5 was drilled near the southwest corner of the property and boring B-6 was drilled along the north property line, north of the underground storage tanks. Soil samples were obtained at 5 foot intervals from each boring. Each sample was field analyzed for the presence of petroleum hydrocarbons using a Thermo Environmental Instrument Model OVM 580B photoionization detector (PID). The soil types encountered consist of fine to medium grained silty sands in the upper 8 to 11 feet. These soils were underlain by fine to coarse grained poorly graded sands with well-rounded gravels to the maximum depth explored, approximately 31 feet below surface. Auger refusal occurred at depths of approximately 31 feet in boring B-5 and approximately 28 feet in boring B-6 due to the presence of gravels and possibly cobbles. The ground water encountered by Evax Technologies, Inc. in their March, 1990, investigation was not encountered in either boring drilled on October 9, 1990. ~ Soil samples collected from depths of 20 and 25 feet from both borings were submitted to a State certified laborato~ for analyses for concentrations of benzene, toluene, ethylbenzene, xylenes, and total petroleum hvdrocarbons as gasoline. Toluene, xylenes, and total petroleum hydrocarbons as gasoline were detected in the soil sample collected from a depth of 25 feet from boring B-5. No hydrocarbon constituents were detected in the other analyzed samples. Based on information provided by California Water Service Company, there are two domestic water supply wells located within one-half mile of the site. Both wells are owned by the California Water Service Company. Depth to static ground-water levels from both wells taken in October, 1990, reveal a depth of 162 feet in the well located at 32nd Street and Claflin Avenue, identified as Station 118 (approximately 750 feet southeast of the site), and a depth of 190 feet in the well located at 33rd Street and San D/mas Avenue, identified as Station 33 (approximately 1,750 feet east of the site). The well at Station 115 is active and pumps at an average rate of 886 gallons per minute. The well at Station 33 is active and pumps at an average rate of 560 gallons per minute.

The box has a watertight seal to protect against surface water infiltration and requires a specially-designed wrench to open. This design discourages vandalism and reduces the possibility of accidental disturbance of the well. Ground-W. atcr Sampling Prior to developing, the wells will be subjectively analyzed for floating product and/or product sheen by lowering a bailer approximately halfway through the air/water interface in the well. Depth to water in each well will also be measured. The wells will then be developed by swabbing, surge- pumping, or another suitable method until the discharge from the wells is relatively clean and free of suspended sediment. Each well will then be purged of approximately three to four well volumes of water and/or until temperature, pH, and conductivity readings stabilize. Each well will then again be subjectively analyzed. Any floating product observed in the wells will be removed prior to sampling, using a bailer. If the product can not be removed from any of the wells, a final measurement of the product thickness will be made and that particular well will not be sampled. Ground-water level will be allowed to recover to approximate static conditions in the wells, and the water level will again be measured. If the water level is at or greater than 80 percent of the initial measured level, a clean bailer will be used to collect a sample from the surface of the water in the well. Any subjective evidence of product detected in the well will be recorded. Water samples will be collected using cleaned disposable bailers. A new bailer and rope will be used for each well. The water samples will be sealed in laboratory-cleaned, 40 milliliter glass vials with Teflon-lined lids. The samples will then be labeled and immediately placed in iced storage. A chain-of-custody record will be initiated by the field geologist or engineer and will accompany the samples to a laboratory certified in the State of California for the analyses requested. A copy of the chain-of-custody record will be included in our final report. EXECUTIVE SUMMARY. Continued Based on the information obtained during this investigation, we present the following conclusions and recommendations. Conclusions · Ground water encountered at 30 feet in March, 1990, was not encountered during this investigation. A maximum depth of 31 feet was drilled at the site before auger refusal occurred due to gravels and possibly cobbles. Since ground water was not encountered in either boring, ground-water monitoring wells were not installed. · The regional ground-water table occurs at approximately 158 feet below the site. It appears that the previously encountered ground-water table was a perched water table. · Since gasoline range hydrocarbons were not detected in any analyzed sample collected from a depth shallower than 25 feet, it is likely that the detected lateral migration'is a result of the hydrocarbons moving on a shallow, perched ground-water table. Recommendations · We recommend that a copy of this report be submitted to the County of Kern, Department of Environmental Health Services, for their review.

(Ultramar) to conduct a subsurface environmental investigation at former Beacon Station Number 571 located at 1102 34th Street in Bakersfield, California. This investigation was conducted based on the results of a previous investigation performed by Evax Technologies, Inc. and presented in their report prepared for Ultramar dated April 1990. The work attempted was that outlined in the Ultramar work plan dated June 19, 1990. The field work was conducted on October 9, 1990. 1.1 Purpose This investigation was designed to evaluate the presence of hydrocarbon constituents in soil and ground water beneath the site through the construction and sampling of three ground-water monitoring wells. 1.2 Scope of Work j'~ During this investigation, two soil borings were drilled at the site. Soil samples were collected from each boring at 5 foot intervals from a depth of 10 feet to approximately 31 feet below surface in boring B-5 and from a depth of 5 feet to approximately 28 feet below surface in boring B-6. Each soil sample was field analyzed for the presence of gasoline range hydrocarbons using a photoionization detector (Thermo Environmental Instruments model OVM 580B). Field detector readings are recorded on the boring logs in Appendix A. Soil samples collected from depths of 20 and 25 feet from each boring were submitted for laboratory analysis for benzene, toluene, ethylbenzene, xylenes (BTEX), and total petroleum hydrocarbons using a gasoline standard (TPHg). The soil returns frOm the drilling operations were stockpiled on plastic sheeting and covered with plastic sheeting. The stockpile is stored near the southwest corner of the sales building within a fenced enclosure. Approximately 1.2 cubic yards of soil was stockpiled. Three soil samples were collected from the stockpile and submitted to the laboratory where they were combined into one composite sample and analyzed for BTEX and TPHg. Former Beacon Station No. 571 SSB 90-1091-01 Bakerafieid, California Page 2 The work proposed included drilling three borings to a maximum depth of 40 feet and placing a 4-inch diameter monitoring well in each boring. However, installation of monitoring wells was not possible due to auger refusal occurring as a result of cobbles encountered near the 30 foot depth in both borings. 2.0 BACKGROUND INFORMATION The following sections provide background information required to gain an understanding of the project. These sections cover the site location and description, regional geology and hydrogeology, and the project history. 2.1 Site Location The site is located at the northwest corner of the intersection of Jewett Avenue and 34th Street in Bakersfield, California. The site occupies a portion of the south half of the northwest quarter of Section 19, Township 29 South, Range 28 East, Mount Diablo Base and Meridian. Elevation at the site is approximately 408 feet above sea level (the National Geodetic Vertical Datum of 1929). The site location .is shown on the Site Vicinity Map (Plate P-l). 2.2 Site Description The site consists of a mini market, two fuel dispenser islands beneath a canopy, asphaltic concrete paved traffic and parking areas, and three underground gasoline storage tanks. The property is bound by 34th Street along the south, Jewett Avenue along the east, a residence to the north, and a vacant undeveloped parcel to the west. The locations of the site facilities are shown on the Site Plan (Plate P-2). 2.3 Regional Geolo~' The site, within the City of Bakersfield, is located in the southern San Joaquin Valley, a northwest trending structural trough bound on the east by the Sierra Nevada, on the south by the Tehachapi Range, and on the west by the Coast Ranges. Bakersfield is underlain by Quaternary alluvial material SSB ENVIRONMENTAL CONSULTANTS, INC. Former Beacon Station No. 571 SSB 90-1091-01 Bakcrafield, California Page 3 deposited by the southwest flowing Kern River. The alluvium is principally derived from granitic sources in the east adjacent Sierra. Tertiary sediments of marine origin underlie the Quaternary section. These are underlain in turn by crystalline basement rocks similar in composition to the Sierra. 2.4 Reeional Hydrogeoloe~, Ground water occurs in unconfined conditions beneath the site at an elevation of approximately 250 feet above mean sea level, or approximately 158 feet below surface. The direction of ground-water flow, based on the 1990 Kern County Water Agency Water Supply Report, is toward the southeast, away from the Kern River which is located northwest of the subject site. Regional clay and silt strata deposited during the Pleistocene and Holocene which divide the Quaternary section into confined and unconfined aquifers do not occur below the site. 2.5 Project History On November 30, 1989, during the installation of overfill protection equipment on the underground storage tanks, soil samples were collected from the tank backfill material and analyzed for the presence of petroleum hydrocarbons. The analytical results indicate the presence of hydrocarbons in the backfill material. Subsequent investigations conducted by Evax Technologies, Inc. involved a soil gas survey and a subsurface soil investigation. The results of the soil gas survey were used to direct the subsurface soil investigation. Three borings were drilled during the course of the soil investigation. Two soil samples collected from each boring were submitted for laboratory analysis. The sample collected from boring 1, from a depth of approximately 24.5 feet, contained 0.64 parts per million TPH gas. No other analyzed compounds were detected in any of the soil samples. A saturated zone was encountered in borings 1 and 2 at approximately 30 feet below surface. Water samples collected through each boring were analyzed for petroleum hydrocarbons. Gasoline fuel constituents were detected in both analyzed water samples. The results of the soil and ground-water samples are presented in Table 1. These investigations were conducted in March of 1990, the results are presented in a report dated April, 1990. SSB ENVIRONMENTAL CONSULTANTS. INC. Former Beacon Station No. 571 SSB 90-1091-01 Bakersfield, California Page 4 The scope of work attempted for this investigation was outlined in the Ultramar work plan dated June 19, 1990. The field work portion of the investigation was conducted on October 9, 1990. This report presents the results of our field and laboratory investigations. 3.0 RESULTS AND FINDINGS The results of the field and laboratory investigations are summarized in the following sections. 3.1 Soil Profile The soils encountered during the drilling operations consisted of fine to medium grained silty sands to depths ranging from 8 feet in boring B-5 to 11 feet in boring B-6. Wood, ceramic, metal and concrete debris was encountered in boring B-5 to a depth of 6 feet. The silty sands were underlain by brown, fine to medium grained poorly graded sands to the maximum depth explored, approximately 31 feet in boring B-5 and 28 feet in boring B-6. Well rounded gravels were encountered in both borings from a depth of roughly 15 feet to the maximum depths explored. Auger refusal occurred at approximately 31 feet in boring B-5 and 28 feet in boring B-6 and was likely the result of encountering an increase in both the size and concentration of gravels and possibly cobbles. Although the current investigation was designed to evaluate perched water previously encountered in March, 1990, no perched water was encountered in any boring drilled during the October, 1990, field investigation. The foregoing is a general summary, of the subsurface conditions encountered in the boring drilled for this investigation. Detailed descriptions of the conditions encountered in the boring are presented on the boring log in Appendix A. The stratification lines shown on the log represent the approximate boundary, between soil types; the actual in-situ transition may be gradual. SSB ENVIRONMENTAL CONSULTANTS, INC.

SSB 90-1091-01 Bakcrsficld, California Page S 3.2 Soil Sample Analytical Results Two soil samples collected from each of the exploratory borings and a composite of three subsamples collected from the soil stockpile were submitted to a State certified laboratory for analysis of selected gasoline constituents. The results of the analyses from this and previous investigations conducted at the site are presented in Table 1. The complete laboratory results, quality control data, and chain of custody documentation that pertain to this investigation are presented in Appendix B. Sample handling and chain-of-custody procedures are presented in Appendix C. 3.3 Canvass of Nearby Wells Information regarding water supply wells was obtained through inquiries made with the City of Bakersfield, Kern County Resource Management Agency Department of Environmental Health Services, and the California Water Service Company. There are two water supply wells located within one half mile of the site, owned by California Water Services. The closest well is located approximately 750 feet southeast of the site at 32nd Street and Claflin Avenue and is identified as station 118. The well is active and has an average pumping rate of 886 gallons per minute. Static water level for the well, taken in October of 1990, was approximately 162 feet below surface. The other well is located approximately 1,750 feet east of the site at 33rd Street and San Dimas Avenue and is identified as station 33. This well is active and pumps at an average rate of 560 gallons per minute. Static water level for the well, taken in October of 1990, is approximately 190 feet below surface. The well locations are indicated on Plate P-3. SSB ENVIRONMENTAL CONSULTANTS, INC. Former Beacon Station No. 571 ,, SSB 90-1091-0! Bakersfield, California ~ Page 6 \.

Former Beacon Station No. 571 SSB 90-1091-01 Bakersfield, California Page 7 4.0 EVALUATION The soil types encountered consist of fine to medium grained silty sands in the upper 8 to 11 feet. These soils were underlain by fine to coarse grained poorly graded sands with well-rounded gravels to the maximum depth explored, approximately 31 feet below surface. Ground-water samples were not obtained during this investigation since ground water was not encountered in either of the borings. The maximum depth drilled during this investigation was approximately 31 feet below surface, deeper than the previous investigation. According to the 1990 Kern County Water Agency Water Supply Report, the depth to ground water is approximately 158 feet. The depth to ground water in the closest California Water Service Company domestic water supply well was approximately 162 feet, measured in October of 1990. Therefore, the ground water encountered in the previous investigation is likely a perched ground-water table. Of the soil samples collected from the five borings drilled at the site, only two of the samples collected from approximately 25 feet contained detectable gasoline range hydrocarbons. None of the other analyzed samples contained detectable levels of gasoline range hydrocarbons. 5.0 CONCLUSIONS On the basis of our findings, we present the following conclusions: The ground water encountered in the March, 1990, investigation was not encountered during the field portion of the current investigation which was conducted in October of 1990. The maximum depth drilled in October exceeded the maximum depth drilled in March. It appears that the shallow ground water encountered in March was a perched ground-water table. 2) The regional ground-water table lies approximately 133 feet below the deepest sample analyzed during this investigation (ground water occurs at approximately 158 feet below surface). SSB ENVIRONMENTAL CONSULTANTS, INC. Former Beacon Station No. $71 SSB 90-1091-01 Bakersfield, California Page 8 6.0 RECOMMENDATIONS It is recommended that a copy of this report should be submitted to the County of Kern Department of Environmental Health Services for their review. 7.0 LIMITATIONS The evaluation and conclusions contained in this report are based on site conditions as they existed at the time of our field investigation and further assume that probes, such as exploratory borings and analyzed samples are representative of the subsurface conditions at the site, i.e., the subsurface conditions everywhere are not significantly different from those disclosed by the probes. If subsurface conditions different from those encountered during our explorations are observed or appear to be present, we must be advised promptly so that we can review those conditions and reconsider our conclusions where necessary. If there is a substantial lapse of time between the submission of our report and the start of additional work at the site, or if conditions have changed due to natural causes at or adjacent to the site, we urge that our report be reviewed to determine the applicability of the conclusions considering the changed conditions and time lapse.

Each soil sample was collected by driving a Large Ring Sampler equipped with 2-1/2 inch diameter brass. sleeves into the soil approximately 18 inches beyond the cutting head of the auger. The ends of each sample sleeve retained for analysis were covered with teflon tape, capped with plastic end caps, sealed with adhesiveless tape, and labeled with pertinent information such as sample number, date and time collected, sample location, and sampler. Each sample was immediately placed in an ice chest and cooled to 4°C using blue ice. APPENDIX C-2 Sample Shipment and Chain-of-Custody Procedures Sample Shipment and Chain-of-Custody Procedures Complete records were kept on each sample including sampling date, sample type, location, and other pertinent information. The sample containers were banded and sealed with chain-of-custody seals. The samples were cooled to 4°C at the site and maintained at that temperature until delivered to a State certified laboratory. Chain-of-custody procedures, generally described in Test Methods for EvaluatinK Solid Waste, SW-846, U.S. EPA, Second Edition, were followed. A chain-of-custody form accompanied the samples from the place of collection to the testing laboratory, and through the completion of the analytical process. The chain-of-custody form included project identification information, the sample type and number, the date and time of sampling, the chemical analyses requested, and the identity of the person taking possession at each change of custody.

As Received Basis Comments: C-~a!ifornia D.O.H.S. Cert. ~102 PROCEDURES Soil Gas Survey The temporary vapor probes installed for the investigation were constructed of 1/2-inch diameter Schedule 40 steel pipe. A point was forged on one end. A 24-inch range of 3/16-inch perforations were drilled into the probe beginning at 3 inches from the point (Figure A). The vapor probes were driven pneumatically into the soil. In locations where the soil was covered by concrete or asphalt, a 1-inch diameter hole was drilled through the surface material with an electric roto-hammer to facilitate probe installation. After installation, a vacuum was applied to each probe to extract soil gas. One psi sample pressure was maintained during the analysis. Sample flow rate and instrument pressures were checked before each test. The soil gas.was sampled through a 1/4-inch Teflon sample line that was connected to a stainless steel well head fitting. Use of Teflon tubing minimizes sample loss through adsorption and the possibility of distorted results from a sample line contaminated by a previous analysis. Leak checks were performed on the sample line before and during the analysis. Filters were used extensively throughout the system to remove foreign material from the sample pathway. The sample line was connected to a diaphragm pump located in a mobile laboratory. The extracted soil gas was analyzed using a Beckman Model 400 Total Hydrocarbon Analyzer equipped with a Flame Ionization Detector (FID) and the results recorded on a Houston Instruments chart recorder. The Beckman Model 400 was calibrated using certified standards of propane in nitrogen. The instrument was recalibrated periodically throughout the day using certified standards. A fork lift was used to remove the temporary vapor probes from the soil after the investigation was completed. Upon removal of the probes, the holes created by the vapor probes were sealed with bentonite and Portland cement (Figure B). Soil Borings The drilling and sampling equipment were thoroughly steam cleaned before drilling began to prevent the introduction of off-site contamination. The soil borings were drilled using an 8-inch, nominal diameter, continuous flight, hollow stem auger mounted to a drill rig. The drill rig was truck- mounted. Soil and Groundwater Sampling and Analysis Soil samples were obtained using a 2-inch I. D. split-barrel sampler advanced into the undisturbed soil by a 140-pound hammer repeatedly falling 30 inches. Pre-cleaned brass liners were placed in the sampler to retain the soil. The blow counts required to advance the sampler were recorded for each 6-inch interval. The sampling equipment was cleaned between each sample event by washing in a Tri-Sodium Phosphate solution and then was double rinsed to prevent cross contamination. The soil samples were immediately sealed in liners using aluminum foil and plastic caps, labeled, and placed on ice for storage and transport to the analytical laboratory. Groundwater samples were retrieved from the borings using a Teflon bailer lowered through the hollow stem auger. The groundwater samples retrieved were placed in 40 ml HCl acidified VOA bottles, labeled, and placed on ice for storage and transport to the analytical laboratory. Upon completion of the borings and sampling, the augers were left in the ground. All borings were sealed with cement grout. The grout was placed through the hollow stem auger as the auger was removed to assure integrity of the seal and to prevent the bore hole from caving. -- A C F TEMPORARY PROBE DETAIL A) CASING: SCHEDULE 40 STEEL P~PE B) ZFNGTH' AS SPEClF~FD ~N RFeORT c) DIAMETER' 1/2 INCH D) PERFORATED LENGTH: AS SPECIFIED IN REPORT E) TIP TO PERFORATIONS: ,3 INCHES F) PERFORATIONS' 5/16 INCH DIA G) FORGED TlR TEMPORARY PROBE DETAIL 269 MOUNT HERk40N RD.. sum?E lO1 '~ DETO0002 n* ......

(Ultramar), a subsurface investigation was conducted at the subject site. The investigation was performed as part of a real estate transaction between Nella Oil Company (Owner of the property) and Ultramar (Lessee of the property). This report presents a description of the investigation procedures, the results of the Soil Gas Survey, the findings of the subsurface investigation, interpretation of analytical testing of soil and groundwater samples, and conclusions and recommendations based on these findings. BACKGROUND The subject site is an operating Beacon Service Station located at the northwest corner of 34th and Jewett Streets in Bakersfield, California. Prior to this investigation, the only subsurface investigative work that had been conducted at this site was the collection of soil samples from small excavations above the fill end of each underground storage tank during installation of over fill containment equipment. These samples were analyzed for the presence of hydrocarbon constituents Benzene, Toluene, Ethylbenzene, and Xylenes (BTEX) and Total Petroleum Hydrocarbons (TPH) as gasoline. The analytical results indicate the presence of hydrocarbons in the samples collected. PURPOSE AND SCOPE The objective of this investigation was to evaluate the possible presence of hydrocarbon constituents in the soil beneath the site. This objective was met through completion of the following tasks: 1) Soil Gas Survey, 2) Soil Borings, and 3) Soil Sampling and Analysis. Ail data collected in this investigation are considered confidential and will not be released to a third party without the written consent of an authorized representative of Ultramar. 2 PROCEDURES Soil Gas Survey The Soil Gas Survey was conducted on 1 March 1990 at the subject site. Eleven temporary vapor probes were installed for the investigation. Placement of the temporary vapor probes was determined in the field by the site investigator (Figure 1). Soil gases were analyzed for total hydrocarbon concentration as vapor (TVH) during the Soil Gas Survey to 1) screen for the presence of hydrocarbon concentration as vapor and, if found, 2) delineate the lateral and vertical extent of hydrocarbon vapor. The survey was conducted at various depth intervals to delineate the lateral and vertical boundaries of hydrocarbon vapor. The depth intervals evaluated include 6 to $ feet, 8 to 10 feet, 10 to 12 feet, 12 to 14 feet, 14 to 16 feet, 16 to 18 feet, and 18 to 20 feet below grade. After the investigation was completed, the temporary vapor probes were removed. Soil Borings On 2 March 1990, three soil borings were advanced to a depth of 30 feet below grade using an 8-inch, nominal diameter, continuous flight, hollow stem auger at locations indicated on Figure 1. A fourth boring, SB3, was terminated at 7 feet below grade due to a subsurface obstruction. Placement of the soil borings was based on the results of the Soil Gas Survey. The borings were logged under the supervision of a State of California Certified Engineering Geologist. The methods used to advance the soil borings are presented in Appendix A. The boring logs are presented as Figures 3 to 6. Soil and Groundwater Sampling and Analysis The drill cuttings and soil samples retrieved from the soil borings were monitored in the field for evidence of hydrocarbon vapor content through the use of a portable organic vapor meter (OVM). The OVM readings recorded at each interval are given on the boring logs (Figures 3 to 6). Selection of soil samples for analysis was based on the OVM readings. Groundwater was encountered at a depth of 30 feet in Borings 1 and 2 (SB1 and SB2, respectively) and at a depth of 25.5 feet in Boring 4 (SB4). ~r~d~at~r sample~ were retrieved from SB1 and SB2 thr~ugn~ne u~e ~f a Teflon bailer lowered through the hollow stem auger. The methods used for soil and groundwater sampling are presented in ~pendix A. Groundwater from SB4 could not be sampled due to flowing sand conditions. The soil and groundwater samples were transported under Chain-of-Custody documentation to a State of California, Department of Health Services certified analytical laboratory located in Bakersfield, California. Soil cuttings derived from the borings were stockpiled on- site and covered with plastic. Approximately 110 gallons of water generated from steam cleaning the augers were retained on-site in two 55-gallon drums. RESULTS Soil Gas Survey The total hydrocarbon concentrations as vapor (TVH) recorded at the temporary vapor probes at the depth intervals tested are given in Table 1. '/~ Hydrocarbon vapors were detected at depths greater than 14 feet only. At Probe E, vapor concentration increased with increasing depth. The highest TVH as vapor concentration, 22,200 parts per million (ppm), was recorded at 16 to 18 feet below grade at Probe F at the southern end of the fuel dispenser islands (Figure 2). Detectable vapor concentrations were recorded at 16 to 18 feet at Probes E and I, east and west of Probe F, respectively, and Probes G and J, both of which are south of Probe F near the property boundary at 34th Street. Soil Characterization The soils at the site, as encountered in the borings, consist of interbedded silty sand, fine- to coarse-grained sand, and gravel to depths of 30 feet below grade (limits of borings). The near surface soils (to 13 feet depth) consist of loose, light to medium brown, silty to fine-grained sand. The fine-grained sediments are underlain by interbedded layers (less than 5 feet thick) of medium- to coarse-grained sand and gravel. Groundwater was encountered at a depth of 25.5 feet in SB4 and at 30 feet in SB1 and SB2. The borings were terminated upon int~r_~qc~.9~_g~gu~d_w~er. SB3 was terminated at a depth °~f~7 feet'due to an obstruction. The soil cuttings derived from the borings and the soil samples were monitored during drilling for the presence of volatile hydrocarbon vapors using an OVM. Hydrocarbon vapor concentrations of 179 to 892 ppm were detected in the soils at depths below 15 feet in SB1, SB2, and SB4. Soils encountered between 7 and 9 feet in SB4 were discolored to dark gray, although the soils did not emit detectable levels of volatile hydrocarbons. The soils encountered between 20 and 25 feet in SB2 appeared discolored and emitted hydrocarbon concentrations of 179 to 449 ppm. Soil and Groundwater Samples Soil samples obtained from SB1, SB2, and SB4 were selected and analyzed for BTEX and TPH as gasoline. The results of the analyses are presented in Table 2. The analytical testing did not detect the presence of petroleum constituents BTEX in any of the samples. TPH as gasoline was detected at 0.64 ppm in the sample from SB1 obtained at a depth of 24.5 feet. Groundwater samples were retrieved from SB1 and SB2. The samples were analyzed for BTEX and TPH as gasoline (Table 3). Detectable concentrations of BTEX and TPH as gasoline were found in both samples. CONCLUSIONS The results of the Soil Gas Survey indicate that concentrations of hydrocarbon as vapor are located in the vicinity of the southern end of the fuel islands and south near the property boundary on 34th Street. The only TPH as gasoline concentration detected in the soil samples analyzed was 0.64 ppm recorded at 24.5 feet below grade in SB1. The remaining soil samples were non-detect for TPH as gasoline. Gasoline constituents BTEX were not detected in any of the soil samples analyzed. Total Petroleum Hydrocarbons as gasoline and gasoline constituents BTEX were detected in groundwater samples retrieved from SB1 and SB2. Based on the groundwater samples being obtained through the auger, the elevated hydrocarbon levels found in the groundwater samples may not be indicative of formation water beneath the site. 5 RECOMMENDATIONS Based on the data obtained from this investigation, it is recommended that three groundwater monitoring wells be installed for the purposes of evaluating the presence of hydrocarbon constituents in the groundwater and to evaluate the hydrologic condition beneath the site. In addition, the data obtained from these wells will be used to evaluate possible sources for the hydrocarbons previously detected in the groundwater. The proposed locations of the groundwater monitoring wells are g~gure 3. DaVid C. ~lick E~gineering Geolo~,~ ~EG~'~i~$ /. // Christopher ~. Peoples Project Engineer, REA 01763 EVAX Technologies, Inc.

Stephenson TEL. NO: 209-583-3324 BACKGROUND: In November, 1989, during installation of overfill equipment, soil samples were collected from small excavations at the fill ends of the UST's. Analysis of the samples indicated that gasoline range hydrocarbons were present in the samples. Based on this information, a soil gas survey was performed and four soil borings were drilled at the site during March, 1990. Two additional borings were drilled during October, 1990, in an attempt to install two monitoring wells. The wells were not installed due to auger refusal from a cobble interval at approximately 30 below surface. In April, 1992, a successful attempt was made and three monitoring wells {MW-I, MW-2, and MW-3) were installed and quarterly monitoring was initiated. SUMMARY OF THIS QUARTER'S ACTIVITIES: Ground-water sampling of all the wells was conducted by SSB Environmental, Inc., on October 14, 1993. BEACON A Member of the Ultramar Group of Companies #1 Quality and Service Beacon Station No. 571 Bakersfield, CA Quarterly Monitoring Report Fourth Qtr. 1993 RESULT OF QUARTERLY HONXTOR]NG: G~ound water was encountered in all three monitoring wells during this sampling event. The measured elevation indicate that ground-water flow is to the southeast with a gradient of approximately 0.01. Analytical results of the samples collected indicate that BTEX and TPHg were not detected. PROPOSED ACTIVITY OR WORK FOR NEXT QUARTER: The next quarterly sampling event is scheduled for January, 1994. SSB Er. il~ommental 'I1~i OomsuItamts, linG. 3140 North Argyle Avenue, Suite 104, Fresno, CA 93727 (209) 292-5736 November 2~) 1993 Mr. Randall lC Stephenson ULTRAMAR INC. 525 West Third Street Hanford, California 93230 Re: Fourth Quarter, 1993 - Monitoring Well Sampling Report Beacon Station Number 571 1102 34th Street Bakersfield, California SSB 90-1091-Q493 Dear Mr. Stephenson: As per your request, SSB Environmental Consultants, Inc., obtained quarterly water samples for laboratory analysis from three ground-water monitoring wells at the former Beacon Station Number 571, located at 1102 34th Street in Bakersfield, California. A vicinity map showing the approximate site location is presented as Plate 1. The water encountered in each monitoring well was from a perched water zone which occurs at a depth of approximately 29 feet below the site. The perched water zone overlies a regional water table which occurs at a depth of approximately 2~0 feet below the site (Kern County Water Agency 1990 Water Conditions Report). Prior to sampling, water from each well was subjectively analyzed for odor, clarity, and floating product. No odor or visual evidence of product was noted in water from monitoring wells MW-2 and MW-3. Elevations of ground water were determined for each well by subtracting depth to ground-water measurements from well head elevations. A site plan is presented as Plate 2 which shows the site facilities, monitoring well locations, ground-water elevations, flow direction, and gradient as of September 15, 1992. The ground-water gradient and flow direction was 0.011 toward the southeast. Depth-to-ground-water data for the site is presented in Table 1. All monitoring wells on-site for the previous three quarters have been found to be dry. According to Kern County Water Agency Personnel, the site is underlain by a former channel of the Kern River. The site is also located near the existing location of the river; above normal seasonal rains and above average discharge from Lake Isabella into the Kern River might account for the strong recharge noted at the site. Beacon Station Number 571 SSB 90-1091-Q493 1102 34th Street Page 2 Bakersfield, California Each monitoring well was purged and sampled as per thc protocols presented in Appendix A. Temperature, specific conductance (EC), and pH were monitored as the wells were purged. The final measurements of these parameters for each well are presented in Table 2.

Prior to sampling the well, approximately four well volumes were removed to bring fresh formation water into the well. Three well volumes were purged using a PVC bailer. The fourth well volume was purged using three disposable bailers. The ground-water was collected using an individually wrapped disposable bailer. The ground-water sample was placed in the appropriate glass containers with teflon-lined lids. Each sample was labeled and immediately placed in an ice chest and cooled to 4°C using blue ice. Sample Shipment and Chain-of-Custody Procedures Complete records were kept on each sample including sampling date, sample type, location, and other pertinent information. The sample containers were banded and sealed with chain-of-custody seals. The samples were cooled to 4°C at the site and maintained at that temperature until delivered to a State certified laboratory. Chain-of-custody procedures, generally described in Test Methods for Evaluating Solid Waste, SW-$46, U.S. EPA, Second Edition, were followed. A chain-of-custody form accompanied the samples from the place of collection to the testing laboratory, and through the completion of the analytical process. The chain-of-custody form included project identification information, the sample type and number, the date and time of sampling, the chemical analyses requested, and the identity of the person taking possession at each change of custody.

A vicinity map showing the approximate site location is presented as Plate 1. The water encountered in each monitoring well was from a perched water zone which occurs at a depth of approximately 32 feet below the site. The perched water zone overlies a regional water table which occurs at a depth of approximately 250 feet below the site (Kern County Water Agency 1990 Water Conditions Report). Prior to sampling, water from each well was subjectively anal.v-zed for odor, clarity, and floating product. No odor or visual evidence of product was noted in water from any of the wells.

Prior to sampling the well, approximately three to five well volumes were removed in order to bring fresh formation water into the well. The ground-water sample was collected using an individually wrapped disposable teflon bailer. The ground-water sample was placed in the appropriate glass containers with teflon-lined lids. Each sample was labeled and immediately placed in an ice chest and cooled to 4°C using blue ice. Sample Shipment and Chain-of-Custody Procedures Complete records were kept on each sample including sampling date, sample type, location, and other pertinent information. The sample containers were banded and sealed with chain-of-custody seals. The samples were cooled to 4°C at the site and maintained at that temperature until delivered to a State certified laboratory. Chain-of-custody procedures, generally described in Test Methods for Evaluatin~ Solid Waste, SW-846, U.S. EPA, Second Edition, were followed. A chain-of-custody form accompanied the samples from the place of collection to the testing laboratory, and through the completion of the analytical process. The chain-of-custody form included project identification information, the sample type and number, the date and time of sampling, the chemical analyses requested, and the identity of the person taking possession at each change of custody.

Overview This Project Safety Plan delineates the basic safety requirements for the Exploratory Soil Boring, and Ground Water Well(s) Installation Program at the former Beacon Service Station located on the Northwest corner of the intersection of 34th and Jewett Streets, in Bakersfield, California. Three (3) soil borings will be drilled with soil samples taken at varied intervals, to the ground water level. Upon contact with the groundwater, the borings will be completed as 4 inch diameter ground water monitoring wells. The soils will be screened for volatile hydrocarbon vapor, and the groundwater will be tested for volatile organic compounds. The analyses of the ground water well samples will include a determination of the following possible contaminants present: TFHC (Total Fuel Hydrocarbons), Ethyl Benzene, and BTX Compounds (Benzene, Toluene, and Xylenes). At the beginning of the project, ambient air. samples (background) will be taken with a PID (Photoionization Detector) to determine the presence or absence of contamination. As the project continues during the day, the personnel on site shall draw periodic air samples to determine the possibility of increases in airborne contamination. SITE HEALTH & SAFETY PLAN The provisions set forth in this plan will apply as minimum rules to be followed by the employees of SSB Environmental and their subcontractors working on this phase of the project. The subcontractors may elect to modify these provisions, but only to upgrade or increase the safety requirements, and only with the concurrence of SSB Environmental and accepted in writing. SITE HEALTH & SAFETY PLAN 2.0 PROJECT SAFETY AUTHORITY A. ON-SITE PROJECT SAFETY Personnel responsible for the project safety are: Mr. David Sholes, Project Manager Site' Safety Officer (SSO) (SSB Environmental) The Site Safety Officer has the authority to suspend work anytime he or she determines that the provisions of the plan are inadequate to ensure worker safety. The Site Safety Officer shall also inform the Property Owner/Station Manager of individuals whose conduct is not consistent with the requirements of the plan. In addition, the Project Manager shall be responsible for the following: Safety Supplies & Equipment Inventory Medical Surveillance Program/Physical Examinations Training Programs/Hazard Communication Accident/Incident Reporting Procedures Decontamination/Contamination Reduction Procedures SITE HEALTH & SAFETY PLAN B. SSB Environmental SAFETY OFFICER The Company Safety Officer reports to the SSB Environmental Senior Management and is responsible for overall safety and loss prevention functions. Responsibilities include: - Health surveillance of all SSB Environmental employees; - Assuring that safety procedures in effect are in compliance with all appropriate federal, state, and company regulations (following the most stringent of the standards); - Maintenance of personnel exposure monitoring records; - Assuring appropriate personal protective equipment is adequate for actual hazards of on-site conditions; - Assuring appropriate hazard areas are identified and marked; ~ Assuring all personnel entering hazard area are in appropriate levels of protection; 6 SITE HEALTH & SAFETY PLAN 3.0 JOB HAZARD ANALYSIS The possible major contaminants to be encountered on the project are Petroleum Hydrocarbons and Volatile Organic Compounds (VOCs). There is currently no known air concentration data available for VOCs emissions in the direct breathing zone of personnel working around the piezometers or exposed soils. Inhalation and dermal (absorption) hazards are the major area of concern, regarding the exposure to VOCs. Results of toxicological studies on animal exposure to pure concentrations of the VOCs that have been detected at the site are detailed in "Handbook of Toxic and Hazardous Chemicals", by M. Sittig (1981), and "Dangerous Properties of Industrial Materials", by N. Irving Sax (1984). An additional reference source used for the development of this -Site Safety Plan is the "Documentation of the Threshold Limit Values", published by the ACGIH (American Conference of Governmental Industrial Hygienists, Inc. Gasoline Gasoline has an appearance of a clear, aromatic, volatile liquid, and is a mixture of aliphatic hydrocarbons. The flash point is listed a-50°F, and has an LEL (Lower Explosive Limit) of approximately 1.3%. The TLV for gasoline is listed as 300 ppm in air. 7 SITE HEALTH & SAFETY PLAN Ethyl Benzene This is a colorless liquid with an aromatic odor. Its flashpoint is listed at 59°F and has a TLV of 100ppm. The hazard class is Flammable Liquid. Benzene Benzene is a common constituent of gasoline and other petroleum product materials. It is a clear, colorless liquid, with a flash point listed at 12°F. The currently established TLV for Benzene is 10 ppm in air. However, the American Conference of Governmental Hygienists (ACGIH) has recommended a TLV of I ppm be adopted. Toluene This material is a flammable, colorless liquid, with a benzol-like odor. The flash point is listed at 40°F. The currently established TLV is 100 ppm in air. SITE HEALTH & SAFETY PLAN X¥1ene This material is a clear liquid with a flash point of 100°F. The TLV is currently established at 100 ppm in air, and is currently under study as a possible carcinogen. It is currently not anticipated that the potential levels of exposure will reach PEL or TLV limits, but this is based solely on limited available specific information. It is planned that inhalation and dermal contact will be the potential exposure pathways of concern. Protective hand coverings, including outer and under gloves will be mandatory for all field operations personnel. In addition, respiratory' protective devices shall be required to be available to each person in the Exclusion Zone, or within easy reach of those persons working in the Contamination Reduction Zone, should irritating odors or irritation of respiratory tract become detectable. The appropriate air-purifying respiratory protective devices, that are required to be available for all personnel working on-site, will be fitted with organic vapor cartridges and dust pre-filters, or..with the high efficiency, organic vapor/HEPA stack type cartridge. Typically, if the respiratory protective devices are worn, the cartridge will need to be changed daily. In addition, during the drilling activities in the areas where increased levels of vapor were previously recorded, personnel working within the exclusion zone will monitor wind direction and speed, and will operate from the upwind side of the boring location. SITE HEALTH & SAFETY PLAN 4.0 RISK ASSESSMENT SUMMARY It is not anticipated that there will be any significant or major potential source of exposures due to the scope of work to be followed on this project. The potential of any increased risk of exposure on other workers or the surrounding community is minimal. The basic potential exposure source would probably originate from airborne dusts, during the drilling of the monitoring wells and those dusts containing low level concentrations of VOCs materials in the soils. Due to this potential, the Contractor will have equipment on-site to provide for dust control during the drilling activities, if it appears that dust control is warranted. Also, perimeter air monitoring, to detect potentially migrating contaminants, may be conducted to ensure no hazardous materials are migrating to the surrounding community. In addition, the borings to be located within the immediate vicinity of the sidewalks or other property boundaries will be drilled in the morning hours, at which time the wind velocity is expected to be lower, thereby reducing the probability of off-site migration of even low concentrations of materials. l0 SITE HEALTH & SAFETY PLAN 5.0 EXPOSURE MONITORING PLAN A. General An air quality monitoring program shall be implemented to provide baseline and on-going air quality data for site operations. The program shall include: 1. A preliminary survey of existing air quality conditions, prior to any surface disturbances and, if possible, under anticipated "worst case" weather conditions, to be used to establish baseline levels for input into the respiratory protection selection process; 2. An on-going evaluation of on-site atmospheric contaminant concentrations during site activities that involve significant surface disturbances; 3. Perimeter monitoring of downwind air quality conditions during significant surface disturbances. SSB Environmental personnel will have a direct reading instrument, photoionization detector (PID) or other direct reading instrument on site to assist with these air monitoring functions. 11 SITE HEALTH & SAFETY PLAN 6.0 PERSONAL PROTECTIVE EQUIPMENT A. Introduction It is important that personal protective equipment and safety requirements be appropriate to protect against the potential hazards at the site. Protective equipment will be selected based on the contaminant type(s), concentration(s), and routes of entry. In situations where the type of materials and possibilities of contact are unknown or the hazards are not clearly, identifiable, a more subjective determination must be made of the personal protective equipment. Field personnel and visitors are required to wear the followix~g clothing and equipment, as a minimum, while on the (~hevron Stat'ion__~ project site: Hard Hat Safety Glasses Long Sleeved Shirts B. Levels of Protection -General Level A: Should be worn when the highest level of respiratory, skin, and eye protection is needed. Level B: Should be selected when the highest level of respiratory protection is needed, but a lesser level of skin protection is required. 12 SITE HEALTH & SAFETY PLAN Level C: Should be selected when the types of airborne substances are known, the concentration is measured, and the criteria for using air=purifying respirators are met. Level D: Should not be worn on any site with respiratory or skin hazards. It is primarily a work uniform providing minimal protection. C. Required Protection It is anticipated that level C work clothing (Standard Tyvek or similar) will be worn during the monitoring well installation phase of the project. In addition, however, the personnel working on the project will be required to wear surgical under gloves (latex), and chemical outer gloves. As the project involves the drilling of soil borings, and the installation of ground water monitoring wells, the potential exposure anticipated is with the contact with potentially contaminated soils and ground water. Historical analytical data indicates this potential contamination to be in the low part per million range. Should the readings with the PID indicate the presence of contaminated materials near the TLVs of the materials analyzed, or approaching the 75-100 ppm range of total organic compounds, the personnel assigned to the project will upgrade their personal protection with appropriate clothing and respiratory protective equipment. That equipment will include the selection of the proper cartridges for the anticipated exposure. SITE HEALTH & SAFETY PLAN SSB Environmental will provide its employees with appropriate personal protective equipment as required. If respirators are deemed necessary, only NIOSH/MSHA certified respiratory protective equipment will be utilized. SSB Environmental sub-contractor(s) are responsible to supply the appropriate safety equipment for their own employees. 14 SITE HEALTH & SAFETY PLAN 7.0 WORK ZONES AND SECURITY MEASURES A. General A site must be controlled to reduce the possibility of exposure to any contaminants present and their transport by personnel or equipment from the site. A control system is required to assure that personnel and equipment working on the hazardous waste site are subjected to appropriate health and safety surveillance. The possibility of exposure or translocation of contaminants can be reduced or eliminated in a number of ways, including: - Setting up security or physical barriers to exclude unnecessary personnel from the general area - Minimizing the number of personnel and equipment on-site consistent with effective operations - Establishing work zones within the site - Establishing control points to regulate access to work zones - Conducting operations in a manner to reduce the exposure of personnel and equipment - Minimizing the airborne dispersion of contaminants - Implementing the appropriate personnel and equipment decon- tamination procedures 15 SITE HEALTH & SAFETY PLAN B. Field Operations Work Area Work areas (zones) will be established based on anticipated contamination. Within these zones prescribed operations will occur utilizing appropriate personal protective equipment. Movement between areas will be controlled at checkpoints. The planned zones are: 1. Exclusion Area (contaminated); 2. Contamination Reduction Area; and, 3. Support Area (non-contaminated). 16 ~ ' °? ~.;'~":"~ ", Illl' __./. .~Ex~sting Boring Location Proposed Boring/Monitoring Well Location GENERALIZED SITE MAP 6/19/90 Former Beacon Station No. 571 1102 - 34th Street Plate Bakersfield, California P-2 SITE HEALTH & SAFETY PLAN 8.0 DECONTAMINATION PROCEDURES A. Introduction As part of the system to prevent or reduce the physical transfer of contaminants by people and/or equipment from on-site, procedures will be instituted for decontaminating anything leaving the Exclusion Area and Contamination Reduction Area. These'procedures include the decontamination of personnel, protective equipment, monitoring equipment, clean-up equipment, etc. Unless otherwise demonstrated, everything leaving the Exclusion Area should be considered contaminated and appropriate methods established for decontamination shall be followed. In general, decontamination at the site consists of rinsing of equipment, personnel, etc., with some amounts of water and washing with detergent water solutions. B. Procedure I. Personnel equipment worn into the Exclusion Area will be decontaminated upon leaving the Contamination Reduction Area. Ail equipment decontaminated will be air dried. 2. The decontamination of equipment, material, and personnel used or working in the Contamination Reduction Area may be somewhat less complex than that used in the Exclusion Area. 3. The spent solution, brushes, sponges, containers, stands, etc., used in the decontamination process must, until shown otherwise, be considered contaminated and must be properly disposed. 17 SITE HEALTH & SAFETY PLAN 9.0 GENERAL SAFE WORK PRACTICES The project operations shall be conducted with the following minimum safety requirements employed: A. Eating, drinking, chewing gum or tobacco, smoking, or any practice that increases the probability of hand to mouth transfer and ingestion of materials is prohibited in any area where the possibility of contamination exists. B. Hands must be thoroughly washed upon leaving a contaminated or suspected contaminated area before eating, drinking, or any other activities transpire. C. Thorough washing of the entire body should be accomplished whenever decontamination procedures for outer garments are in effect. The washing should occur as soon as possible after the final wearing of protective garments. D. Legible and understandable precautionary labels shall be prominently affixed' to containers of raw materials, intermediates, products, mixtures, scrap, waste, debris, and contaminated clothing. E. Contaminated protective equipment shall not be removed from the regulated area until it has been cleaned or properly packaged and labeled. F. Removal of materials from protective clothing or equipment by blowing, shaking, or any other means which may disperse materials into the air is prohibited. G. Personnel on=site must use the "buddy" system when wearing any respiratory protective devices. Communications between members must be maintained at all times. Emergency communications shall be prearranged in case of encountering unexpected situations. Visual contact must be maintained between "pairs" on-site, and each team should remain in close proximity to assist each other if necessary. 18 SITE HEALTH & SAFETY PLAN H. Personnel should be cautioned to inform each other of subjective symptoms of chemical exposure such as headache, dizziness, nausea, and irritation of the respiratory tract. I. No excessive facial hair which interferes with a satisfactory fit of the facepiece-to-face seal, will be allowed on personnel required to wear respiratory protective equipment. J. All respiratory protection sele¢~on, use, and maintenance shall meet the requirements of established SSB Environmental procedures, recognized consensus standards (AIHA, ANSI, NIOSH), and shall comply with the requirements set forth in 29 CFR 1910.134. K. Appropriate work areas for support, contamination reduction, and exclusion will be established. L. SSB Environmental personnel on-site are to be thoroughly briefed on the anticipated hazards, equipment requirements, safety practices, emergency procedures and communications methods, initially and in daily briefings. M. Contact with surface and groundwater shall be minimized. N. Steel toed, boots will be worn on-site at all times. In addition, the following precautions shall be implemented for all personnel working on the project site: Gross decontamination and removal of all personal protective equipment shall be performed prior to exiting the facility. Contaminated clothing will be removed and collected in a drum for disposal The Site Safety Officer will be responsible to take necessary steps to ensure that employees are protected from physical hazards, which could include, - Falling objects such as tools or equipment 19 SITE HEALTH & SAFETY PLAN - Falls from elevations - Tripping over hoses, pipes, tools, or equipment - Slipping on wet or oily surfaces - Insufficient or faulty protective equipment - Insufficient or faulty operations, equipment, or tools All personnel shall be required to wash hands and face before eating, drinking, or smoking Field operations personnel shall be cautioned to inform each other of non-visual effects of the presence of toxics, such as: - Headaches - Dizziness - Nausea - Blurred Vision - Cramps - Irritation of eyes, skin, or respiratory tract - CMn§es in complexion or skin discoloration - Chan§es in apparent motor coordination - Changes in personality or demeanor - Excessive salivation or changes in pupillary response - Changes in speech ability or pattern 20 SITE HEALTH & SAFETY PLAN 10.0 SANITATION $SB Environmental will provide for the proper sanitary, facilities for use by all personnel assigned to the project. These facilities may currently be operational at the facility, or may need to be brought onto the facility property. The personnel not entering the Contamination Reduction Zone or the Exclusion Zone will have sanitary facilities (potable water, toilet, etc.) located in a clean area within the Support Zone. For the personnel entering the Contamination Reduction Zone and the Exclusion Zones, sanitary facilities will be located at the entrance point of the Contamination Reduction Zone, near the personnel decontamination area. 21 SITE HEALTH & SAFETY PLAN 11.0 STANDARD OPERATING PROCEDURES Respiratory Protection Program Guidelines Respirators will be provided by the Company when such equipment is deemed necessary to protect the health of the employee. The Company shall provide respirators which are applicable and suitable for the purpose intended. The employer shall be responsible for the establishment and maintenance of this respiratory protection program. The Site Safety Officer will approve the selection, purchase, and inspection of the mod.els and types of resp. iratory protective devices. A medical evaluation is required prior to wearing any respirator, except where emergency escape respirators are provided. The contract physician shall determine annually if any health or physical conditions exist which would prohibit a worker from being assigned to an area requiring respiratory protection. A record will be retained in the employee's medical file, which will be retained at the medical clinic or doctor's office. Respirators shall not be worn when conditions prevent a facepiece- to-face seal. Such conditions as facial hair, scars, wrinkles, facial diseases, dentures removal, or other disorders could prevent a proper facepiece-to-face seal. In these cases, corrective action will be taken to ensure a proper seal. Contact lenses shall not be worn when using any respirator. For the safe use of any respirator, it is essential that the user be properly instructed in its operation and maintenance. Both supervisors and employees shall be so instructed. Employees shall be instructed and trained in the proper selection and use of respirators and their 22 SITE HEALTH & SAFETY PLAN limitations. The employee shall use the provided respirator in accordance with instructions and training received. All training shall be documented with records retained in the employee's training files. The $SB Environmental Respirator Program will meet the 11 points as specified in Title 29 CFR 1910.134 *, and CAC Title 8. 23 SITE HEALTH & SAFETY PLAN 12.0 EMERGENCY PROCEDURES A. Site Emergency Warning System Several warning systems may be utilized depending on the work site conditions or emergency involved: I. Verbal communications 2. Vehicle horns 3. Portable hand-held compressed gas horns Verbal instructions with or without assistance are used to deal with specific incidents. Horn signals are used to signify an emergency warning. One long blast is used on-site to signify emergency evacuation of the immediate work area to a predetermined location upwind, where a head count will be taken and further instructions given. Repeated short blasts are used on-site or from off-site to signify evacuation of all personnel from the site to the hot line where further instructions will be given after a head count is taken. B. Emergency Equipment The following equipment comprises the basic emergency equipment list, of which all or some shall be available at the work site: 1. Fire extinguishers -dry chemical 24 SITE HEALTH & SAFETY PLAN 2. First aid kits (including chemical burn kit) 3. Combustible gas and oxygen detector analyzers 4.

As you mentioned during our conversation, by providing the following information {project status and a time table for future work), the scheduled administrative hearing will be cancelled. As you are aware, an environmental investigation is being conducted at the above referenced site to evaluate the presence of hydrocarbons in the soil i. and possibly ground water beneath the site. Previous drilling conducted at the site has resulted in aborting the field work due to auger refusal at a depth of approximately twenty-eight {28) to thirty (30) feet from surface. It has been determined that a cobble interval exists beneath the site beginning at a depth of approximately of 28 feet. Based on this. information it is apparent that conventional auger drilling .will not be useful in determining the vertical presence of hydrocarbons beneath the site. To obtain the needed information below the cobble interval, other drilling methods {ie: mud rotary, air rotary, casing hammer) are being explored, which has resulted in a delay in proceeding with the investigation. Of the drilling methods mentioned, it appears that air rotary, possibly combined with auger drilling, will be the best choice. A work plan to perform additional field work is being prepared and will forwarded to your office by November 29, 1991. The work plan will outline the steps that will be taken to asses the possible presence of hydrocarbons in the soil, and ground water if needed, below the cobble interval.

Box 466 Hanford, CA 93232-0466 Re: Former Beacon Station #571 Site Remediation Dear Mr. Stephenson: It has come to the attention of this Department that no action has been initiated towards final characterization and remediation of contaminated groundwater at the former Beacon Station located at 1102 34th Street, in Bakersfield, California. Our most recent review has revealed a time lapse of approximately five (5) months since you were requested to submit information supporting the "no action" option as the preferred method of remediation. It is this Department's position that it is premature to be considering mitigation options since the groundwater contamination plume has not been adequately defined. The site characterization failed to define the extent of groundwater contamination identified during previous borings. As a result, an evaluation of possible mitigation options is inappropriate during this phase of the subsurface investigation. Since a sufficient amount of time has elapsed to perform the required work or advise this Department of your next plan of action, an administrative hearing has been scheduled. The administrative hearing has been scheduled for November 25, 1991, at 10:00 a.m., in our office. Please call this office to confirm your attendance.

In accordance with this Department's guidelines for completion of a site characterization study, a viable mitigation method must be selected. Selection of the mitigation method must be made in conjunction with the environmental contractor and based on information obtained by the site characterization. The selected mitigation method of "no action" cited in your letter which accompanied the report must be supported by your contractor. Additional information must be provided by your contractor to evaluate the nonbeneficial use of the perched groundwater zone encountered and the potential threat to the primary groundwater aquifer beneath the gravelly subsurface found at approximately 31 feet.

Dear Mr. Canas: Enclosed for your review and files is a copy of our consultant's SUBSURFACE ENVIRONMENTAL INVESTIGATION REPORT for the above-referenced Ultramar facility. The investigation was conducted to evaluate the possible presence of hydrocarbons in soil and ground water beneath the subject site. During this investigation it was determined that ground water encountered during previous drilling activities at the site was not encountered in these recently drilled borings. After lengthy review of this information and data obtained from a 1989 Kern County Water Agency Water Supply Report, it was concluded that this first encountered water was perched and seasonal, which may exclude this water from the State Water Resources Control Board Resolution No. 88-63 as a suitable or potentially suitable drinking water source. Based on these conclusions and the soil analytical results, we recommend that no further evaluation of the site is needed at this time and recommend site closure. Please do not hesitate to call if you have any questions regarding this information. Sincerely, ULTRAMAR INC. Randall K.

The proposed work will be performed by an environmental consultant selected by Ultramar Inc. (Ultramar) and includes drilling three soil borings at the site to a depth of approximately 40 feet each; collecting soil samples from the borings for visual inspection and laboratory analysis; constructing a 4-inch-diameter ground-water monitoring well in each boring; purging the monitoring wells and collecting water samples for laboratory analysis; evaluating the ground-water flow direction and gradient using data obtained from the wells; and preparing a Preliminary Report documenting field methodology and presenting the findings, conclusions, and recommendations. As part of a real estate transaction involving the site, Ultramar conducted a subsurface investigation during March 1990. The investigation was in response to the detection of hydrocarbon constituents in soil samples collected from the site during installation of overfill equipment on the underground storage tanks. Additional information obtained from the investigation indicates that hydrocarbon constituents are present in the ground water beneath the site. The laboratory results of the soil samples and information obtained from the investigation have been forwarded to your office. In our opinion, the work described in the enclosed work plan will yield the data necessary to evaluate the presence of hydrocarbon constituents in soil and ground water at the site. BEAC.

The proposed work includes: 1) drilling three approximately 40 foot soil borings at the site; 2) collecting soil samples from the borings for field evaluation and laboratory analysis; 3) constructing a 4-inch-diameter ground-water monitoring well in each boring; 4) developing, purging, and collecting water samples from the wells; 5) analyzing selected soil samples obtained from the borings for gasoline constituents benzene, toluene, ethylbenzene, total xylenes (BTEX) and total petroleum hydrocarbons (TPH) as gasoline; 6) analyzing the water samples collected from the monitoring wells for BTEX and TPH; and 7) preparing a 'Preliminary Report (PR) documenting field methodologies and presenting findings, conclusions, and recommendations. The proposed work will be performed by an environmental consulting firm under the supervision of a registered geologist or professional engineer. Mr. Chris Burger June 19, 1990 Page No. i BACKGROUND AND PREVIOUS WORK The subject former Beacon service station is located on the northwest corner of the intersection of Jewett Street and 34th Street in Bakersfield, California. The site location is shown on the Site Vicinity Map (Plate P-l). The approximate locations of the station facilities are shown on the Generalized Site Plan (Plate P-2) ~-~ On November 30, 1989, soil samples were collect'ed from small excavations at the above-referenced site by a representative of Ultramar Inc. (Ultramar). The samples were collected during installation of overfill equipment on the underground storage tanks at the site and submitted to a State Certified laboratory for analysis of BTEX and TPH. The results of the analyses indicate the presence of hydrocarbon constituents in the soil samples analyzed. The laboratory reports for the samples analyzed are enclosed with this work plan. Based on the analytical results, and as part of a real estate transaction, Ultramar conducted a soil vapor survey at the site. The results of the survey were used to: 1) evaluate the presence of hydrocarbon vapors in the soil beneath the site, and 2) determine boring locations to evaluate the possible presence of hydrocarbon constituents in the soil. The results of this preliminary investigation were forwarded to your office in a report dated April, 1990, prepared by Evax Technologies. Mr. Chris Burger June 19. 1990 Page No. 2 GROUND WATER DATA Based on Spring 1989 information obtained from the Kern County Water Agency, the depth to unconfined ground water in the vicinity of the site is less than 100 feet below ground surface and the direction of flow is to the southeast. Ground water was encountered at approximate depths of 25 and 30 feet in the borings drilled during the previous. / ,~ .... ~- · '~.~ ' .

The proposed work includes drilling three 40-foot soil borings at the site {approximately 15 feet into the saturated zone} and installing a 4-inch-diameter ground-water monitoring well in each boring. Based on the ground-water data, one of the proposed borings will be located downgradient of the tank site and fuel dispensers, one will be located upgradient, and one will be located cross-gradient. The proposed boring locations are presented on Plate P-2. The proposed borings and monitoring wells should be sufficient to supply the necessary information to evaluate the presence of hydrocarbon constituents in the ground water beneath to the subject site. PROPOSED WORK ~,- 'iThe proposed work is recommended to evaluate the extent of hydrocarbon r,.-. constituents in the ground water beneath the site. The following tasks will be ~'~ .~. performed by an environmental consultant selected by Ultramar: 1) Prepare a Site Safety Plan discussing the precautions and protective equipment required for work at the site. 2) Acquire all necessary permits from the appropriate regulatory agencies to drill and install the monitoring wells. Mr. Chris Burger June 19, 1990 Page No. 4 3) Drill three 10- to 12-inch diameter soil borings to a maximum depth of approximately 40 feet each. 4) Collect and classify relatively undisturbed soil samples from the borings at 5 foot intervals begining at 5 feet below ground surface. An OVM or similar device will be used in the field to subjectively evaluate the potential concentration of hydrocarbons in the soil samples collected above the saturated zone. 5) Submit an estimated two soil samples per boring for laboratory analysis (one sample associated with the highest OVM reading and one from directly ~'' above the saturated zone). The samples will be analyzed for the purgeable gasoline constituents BTEX, and TPH as gasoline. 6) Construct one 4-inch-diameter, PVC cased ground-water monitoring well in each boring and develop the new wells for sampling. 7) Collect ground-water samples from the monitoring wells and submit the samples for laboratory analysis for BTEX and TPH 8) Survey the wells using a land surveyor and evaluate the ground-water ~ gradient and flow direction. ~a"~,~9) Perform a well search to identify any existing water wells within one-half mile of the site 10) Prepare a PR summarizing field and laboratory procedures, findings, interpretations, conclusions, and recommendations. Site Safety Plan Field work performed by Ultramar's consultant at the site will be conducted in accordance with a Site Safety Plan. This safety plan will describe the basic safety requirements for the subsurface environmental investigation, drilling soil borings, and installation of monitoring wells at the site. The Site Safety Plan is applicable to personnel and subcontractors of the consultant. The consultant's personnel {and subcontractors) scheduled to perform work at the site will be briefed on the contents of the Site Safety Plan before work begins. A copy of the Site Safety Plan will be kept at the site and will be available for reference by appropriate parties during work at the site. A Site Safety Officer will be appointed for the duration of the subject work at the site. Mr. Chris Burger June 19, 1990 Page No. 5 Drilling and Soil Sampling Appropriate permits will be acquired prior to commencement of drilling. Underground Service Alert will be contacted prior to drilling to delineate public utility lines. Initially, each borehole will be hand-augered to a minimum depth of 5 feet. The soil borings will be drilled using continuous-flight, hollow-stem augers and a truck-mounted drill rig. The auger flights will be steam-cleaned prior to each use to minimize the possibility of cross-contamination between borings. Drilling will be performed under the guidance of a field geologist or engineer, and the earth materials encountered in the borings will be logged as drilled. Soil samples will be logged using the Unified Soil Classification System and recorded onto a boring log form. During drilling, soil samples from the borings will be collected at 5 foot intervals using a California-modified, split-spoon sampler (2.5-inch-inside-diameter) equipped with clean brass sleeves using the protocols described in the appendix. The borings will be advanced approximately 15 feet beyond the depth that g~ound water is encountered and the monitoring wells will be constructed following the procedures presented in the attached appendix. Subsequent water sampling will be conducted following the procedures presented in the appendix. Mr. Chris Burger June 19, 1990 Page No. 6 Laboratory Ana)yses An estimated two soil sample from each borehole (e.q., the sample associated with the highest OVM reading and the last sample above the saturated zone) will be selected for laboratory analysis. The selected samples will be analyzed in a California State certified laboratory for BTEX, using EPA approved methods, and TPH as gasoline by modified LUFT Guideline methodologies. Detection limits suitable for the soil tests requested and concentrations present will be stated on the laboratory reports. Copies of the laboratory reports will be included in the final report. Ground-water samples will be collected from the monitoring wells installed at the site. These samples will be submitted for laboratory analysis for BTEX and TPH as gasoline using approved EPA methods. Detection limits suitable for the water tests requested and concentrations present will be stated on the laboratory reports. Copies of the laboratory reports will be included in the final report. Measurement of Ground-Water Gradient A land surveyor will survey the well-head elevations (measured-to the nearest 0.01 foot) of the new wells with respect to mean sea level. The survey data and ground-water measurements from each well will be used to determine the ground-water gradient and direction of local ground-water flow. Elevation differences between the wells will be combined with measurements of the depths to static water in the respective wells to calculate the differences in water level. The calculations will be used to prepare a ground-water potentiometric surface map for the vicinity of the site. The gradient will be interpreted on an approximate quarterly basis until a different frequency is warranted. Mr. Chris Burger 3une 19, 1990 Page No. 7 Well Search In conjunction with this investigation, a search of available public records will be conducted to determine the extent of ground-water usage in the area of the site and to identify existing water wells, if any, within a 1/2-mile radius of the site. Inquiries will be made to the State Department of Water Resources, the County of Kern, and the City of Bakersfield. Report Preparation A report prepared by the consultant summarizing the soil conditions encountered during the drilling, field and laboratory procedures, well construction details, analytical results, direction of ground-water flow and gradient, and recommendations for further work (if needed) will be presented to Ultramar approximately 45 days after field work is completed. After Ultramar review, the report will be forwarded to the Fresno office of the California Regional Water Quality Control Board, and Kern County Environmental Health Department. APPENDTX FIELD PROTOCOLS Soil Sampling The soil samples obtained from the borings will be collected by advancing each boring to a point immediately above the sampling depth, then driving the sampler into the native soil through the hollow center of the auger. The sampler will be driven 18 inches with a standard 140-pound hammer dropped 30 inches per blow. The number of blows required to drive the sampler each successive 6 inches will be counted and recorded on the boring log to give an indication of soil consistency. A soil sample from each recovered sample interval, above the saturated portion of the boring, will be analyzed in the field with a photoionization detector or a similar instrument. The data will be recorded on the boring logs. Soil samples selected for chemical analysis will be sealed with teflon sheets or aluminum foil, plastic end caps, and airtight tape. The samples will then be labeled and immediately placed in iced storage for transport to a California State Certified laboratory which will perform the required chemical analyses. A Chain of Custody Record will be initiated in the field and will accompany the samples to the laboratory. A copy of the Chain of Custody Record will be included in the final report. Construction of Monitorinq Wells The monitoring wells will be constructed of flush thread-jointed, Schedule 40 PVC casing. No chemical cements, glues, or solvents will be used in well construction. The screened portion of the well will consist of factory- perforated casing with 0.020-inch-wide slots. The well screen will extend from the total depth of the well to a depth of approximately 5 feet above measured ground-water levels at the site to allow monitoring throughout the year despite expected seasonal fluctuations of ground water. The annulus of the well will be packed with #16 Monterey sand, or similar, to approximately 2 feet above the screened interval. A 1- to 2-foot-thick bentonite plug will be placed above the sand as a seal against cement entering the sand pack. The remaining annulus will be backfilled with a slurry of water, neat cement, and 5 percent-bentonite to a few inches below grade. A locking well cap and padlock will be installed on each well head, and a traffic-rated, cast-aluminum utility box with a PVC apron will be placed over each well and set with concrete flush with the surrounding station pad. The box has a watertight seal to pro~gainst surface-water infiltration and requires a specially-designed wrench to open. This design discourages vandalism and reduces the possibility of accidental disturbance of the well. Ground-Water Samplinq Prior to developing, the wells will be subjectively analyzed for floating product and/or product sheen by lowering a bailer approximately halfway through the air/water interface in the well. Depth to water in each well will also be measured. The wells will then be developed by swabbing, surge-pumping, or another suitable method until the discharge from the wells is relatively clean and free of suspended sediment. Each well will then be purged of approximately three to four well volumes of water and/or until temperature, pH, and conductivity readings stabilize. Each well will then again be subjectively analyzed. Any floating product observed in the wells will be removed prior to sampling, using a bailer. If the product can not be removed from any of the wells, a final measurement of the product thickness will be made and that particular well will not be sampled. Ground water level will be allowed to recover to approximate static conditions in the wells, and the water level will again be measured. If the water level is at or greater than 80% of the initial measured level, a clean bailer will be used to obtain a sample from the surface of the water in the well. Any subjective evidence of product detected in the well will be recorded. Water samples will be collected using a Teflon bailer cleaned with Alconox and rinsed with tap and deionized water. The water samples will be sealed in laboratory-cleaned, 40-milliliter glass vials with Teflon-lined lids. The samples will then be labeled and immediately placed in iced storage. A Chain of Custody Record will be initiated by the field geologist or engineer and will accompany the samples to a laboratory certified in the State of California for the analyses requested. A copy of the Chain of Custody Record will be included in our final report. Ultramar Ultramar Inc. 525 W. Third Street P.O.

Box 466 Hanford, California 93232 February 5, 1990 Mr. Steve McCalley Department of Environmental Health Kern County 1700 Flower Street Bakersfield, California 93305 SUBJECT: BEACON SERVICE STATION NO 571, 1102 34th STREET, BAKERSFIELD, CALIFORNIA Dear Mr. McCalley: On November 30, 1989, soil samples were collected from small excavations at the above-referenced site by a representative of Ultramar Inc. (Ultramar). The samples were collected during installation of overfill equipment on the underground storage tanks at the site and submitted to a State Certified laboratory for analysis of hydrocarbon constituents benzene, toluene, ethylbenzene, total xylenes (BTEX) and total petroleum hydrocarbons (TPH) as gasoline. The results of the analyses indicate the presence of hydrocarbon constituents in the soil samples analyzed. The laboratory reports for the samples analyzed are enclosed with this letter. Based on the analytical results, and as part of a real estate transaction, Ultramar will be conducting a soil vapor survey at the site. The results of the survey will be used to: 1) evaluate if, and to what extent, hydrocarbon constituents may be present in the soil beneath the site and 2) to determine if borings are needed to delineate the possible presence of hydrocarbon constituents in the soil. If soil borings are needed at the site they will be drilled following completion of the survey. The field work will be performed by an environmental consultant selected by Ultramar and includes conducting the field work and preparing a report documenting field methodology and presenting findings, conclusions, and recommendations. BEAC-,,-N A Member of the Ultramar Group of Companies #1 Qualit~ and Service Mr. Steve McCalley Kern County Environmental Health February 2, 1990 Upon completion, the report will be forwarded to your office for review. Please do not hesitate to call if you have any questions regarding this information. Sincerely, ULTRAMAR INC. Environmental Specialist Enclosures 571-wp ENVIRONMENTAL LABORATORIES, INC.
