Union Avenue in Bakersfield, California. Laboratory analyses revealed soil beneath the 8,000 gallon gasoline tank was impacted with petroleum hydrocarbons. In June, 1991 BSK and Associates conducted a Site Characterization of the facility by advancing five (5) borings in the vicinity of the former tanks. At thi~ time it was discovered that the plume extended 65 feet in depth but the boring arrangement failed to fully define the lateral extent of the plume. In May 1992 AquaGeosciences, Inc. (AGI) was retained by the client to implement a Remedial Action Plan and complete the lateral assessment of the plume. Six (6) borings were advanced in May 1992 by AGI and converted to vapor extraction and vapor inlet wells for remediation purposes. In November 1992, vapor extraction wells VE-1, VE-2, and VE-3 were manifolded to an Internal Combustion (IC) engine for extraction and destruction of hydrocarbon vapors. Beginning in January, 1994, AGI began cycling the remediation equipment to allow concentrations to accumulate. By May 1994 it was calculated that the engine was using supplemental fuel exclusively and that remediation of the site may be complete. On August 25, 1994, AGI advanced two (2) confirmation borings to determine whether remediation was complete. The first confirmation boring, C-1, was advanced in the center of the plume while the second boring, C-2, was advanced approximately 20 feet to the north of C-1. Maximum concentrations of TPH gasoline reported in the confirmation borings was 58 ppm while the maximum Benzene concentration reported was 0.027 ppm. This report documents the project history throughout the remediation process and contains all data from the confirmation borings. A risk assessment for groundwater and upward migration of contaminants to the surface is included. The risk assessment and subsequent data evaluation indicate that the environmental risk associated with the remediatad site are extremely low. It is therefore, AGl's opinion that remediation of the soil is complete and no further remediation is necessary. 2.0 BACKGROUND The site is located at 1898 So. Union Avenue, Bakersfield, California as shown on Exhibit 1. 2.1 Facility Description The property is currently occupied and is operating as the Griffith Company. The facility consists of an office building, equipment yard and maintenance bays. Formerly located at the site were three (3) underground fuel storage tanks, two fuel dispensers and appurtenant piping (Exhibit 2). 2 i: 3.0 PROJECT H'STORY In January, 1991, MP Vacuum Service Company removed one (1) 8,000 gallon diesel underground storage tank, one (1) 8,000 gallQn gasoline underground storage tank, one (1) 500 gallon gasoline underground storage tank, two fuel dispensers and the associated product lines. Soil samples were collected from beneath each tank, dispensers and the product lines at 2 and 6 foot depths. The samples were submitted to SMC Laboratories, Inc., a State Certified Laboratory for the specified analysis. The samples were analyzed for Total Petroleum Hydrocarbons (TPH) as diesel, gasoline and volatile aromatics (BTEX). The laboratory reported concentrations of TPH as gasoline beneath the former 8,000 gallon gasoline tank and the gas and diesel product lines. The concentrations in the vicinity of the east gasoline tank were reported as 5,400 ppm at 2 feet and 5,000 ppm at 6 feet. BTEX was also detected and increased with depth. The concentrations detected under the gasoline and diesel product lines were 420 ppm at 2 feet and 340 ppm at 6 feet beneath the gas line and 6.2 ppm at 2 feet and 300 ppm at 6 feet beneath the diesel line. Minimal concentrations of BTEX were detected. TPH as diesel was detected beneath the east end of the diesel tank at a concentration of 2,700 ppm at 2 feet which increased to a concentration of 3700 ppm at 6 feet. Concentrations of BTEX were detected and increased with depth. Total Petroleum Hydrocarbons were not detected beneath the former location of the 500 gallon gasoline tank, the west end of the 8,000 gallon diesel tank or the gasoline and diesel dispensers. On the basis of the laboratory analyses, the Kern County Environmental Health Services Department requested that a characterization be conducted at the site to assess the extent of contamination. Griffith Company contracted with BSK & Associates to perform a site characterization. BSK & Associates conducted the investigation and found gasoline impacted soil extending to a depth of approximately 75 feet and laterally distributed in a radial pattern centered about the former 8,000 gallon gasoline tank. These findings were presented in BSK & Associates report dated May 15, 1991 and analytical results are summarized in Table 1. 3 j'~ !.

AquaGeosciences, Inc. (AGI) was retained to remediate site by using vapor extraction of the vadose zone. Additional site assessment was completed concurrent with the initial stage of the remediation process by advancing six (6) borings (VE-1, VE-2, VE-3, VI-1, VI-2, and VI-3). These boring were completed as vapor extraction (VE) and vapor inlet (VI) wells which were drilled from May 21 through the 27, 1992. A summary of the analytical results are presented as Table 2. Exhibit 3 depicts the boring locations and aerial extent of the plume. 4 ¡. TABLE 2.

The IC engine consisted of a modified VW engine equipped with a sophisticated oxygen sensor/carburation system, ignition electronics, a lead removal canister, a 3-way TWX Catalyst, and a 2-way PTX Catalyst. The IC engine was designed to run at 3,000 rpm which translates to 147 Ibs/day of fuel consumption assuming a 90% efficiency rate. 5 i" The IC engine was removed from the Griffith site on January 11, 1993 after completing 500 hours of run time. A short interim hiatus was given to the site so the vadose zone could re-charge. The extraction was reinitiated in March, 1993 and ran continuously until January, 1994. Beginning in January, 1994, AGI began cycling the system to allow the vadose zone time to recover. In May, 1994 it was calculated that the engine was running on supplemental fuel exclusively which suggested that remediation of the site may be complete. On August 25, 1994 AGI advanced two (2) confirmation borings, one in the center of the former plume (C-1) and the other to the north toward the outer extent of the plume (C-2). Exhibit 3 depicts the location of the confirmation boring in relationship to former plume, borings, and extractionlinlet wells. 4.0 FIELD ACTIVITIES AGI advanced two (2) confirmation borings through the preexisting plume to determine whether remediation was complete. Boring C-1 was advanced to 80 feet in the center of the former plume. Boring C-2 was advanced approximately 22 feet north on C-1 to a depth of 80 feet. Exhibit 3 shows locations of the two confirmation borings. 4.1 Boring Methods Two (2) soil borings, C-1 and C-2, were advanced using a CME-75 rig with a eight inch diameter hollow stem continuous flight auger in accordance with ASTM Method D- 1452-80 for soil investigations and sampling by auger borings. The augers were steam cleaned prior to advancing the boring. The lithology and other pertinent data was recorded on field boring logs in accordance with Method D 2488-84 for visual description a.nd identification of soils. Soil generated during the drilling process was plac.od in drums at the site while waiting for analytical confirmation. A cement slurry was used to abandon the borehole. 4.2 Soil Sampling Soil samples were collected through the auger in 2 1/2-inch diameter brass sleeves driven in a split spoon sampler by a 140 pound hammer with a 30-inch drop in accordance with ASTM Methods D1586-84 for split-barrel sampling of soil and D1587- 83 for thin-walled tube sampling of soils. The brass sleeves and sampler were washed in Alconox prior to each use. Soil samples were taken at depths of 5 foot intervals to a total depth of 80 feet in both borings. The blow counts, recovery, and lithology were recorded on field logs. Lithology was then described by an experienced environmental geologist under the direct supervision of a California Registered Geologist in accordance with ASTM 6 procedure D2488-84 (Standard Practice for Description and Identification of Soils). One brass sleeve with soil from each interval was sealed with teflon tape, capped, secured with duct tape, labeled in accordance with EPA protocols, recorded on a Chain-of-Custody form, placed in a cooler at 4° centigrade, and transported to Halcyon Laboratories, a California Certified Laboratory with the Chain-of-Custody for the specified analyses. Appendix A contains the boring logs for the confirmation borings. 4.3 Field Screening of Soil Samples Soil samples were collected using three (3) six-inch brass tubes installed inside a split-spoon sampler. The middle sample tube was immediately sealed and prepared for transport to a state certified lab and stored in an iced cooler upon collection. The bottom tube was used for lithologic description and the top tube was used for field screening. The material from the top tube was placed in a mason jar to approximately 50 percent capacity, shaken, and stored for a period of 15 minutes. A standard headspace reading was collected at this time and noted on the boring log. Field screening was accomplished using a Flame-ionization detector (FID). 4.4 Soil Analysis Thirty two (32) confirmation soil sample~ were sent to Halcyon Laboratory, a California State Certified Laboratory in accordance with state guidelines and EPA protocols. A hold was placed on several samples until initial analytical could be reviewed. All samples were analyzed for Total Petroleum Hydrocarbons (TPH) as gasoline and volatile aromatics (BTEX) using EPA Method 8015 modified and 8020, respectively. Laboratory results are available in Appendix B. 5.0 SITE GEOLOGY AND HYDROLOGY Surface soils in the vicinity of the Griffith Company site are classified as Quaternary alluvium. The soils consist of alluvial fan and stream channel deposits composed of non-uniform and discontinuous lenses of fine and coarse grained sediment. Soils encountered during the confirmation borings consist of interbedded sand and silty sands from surface to 65 feet. These sands grade from gravel to very fine with an abundant amount of silty matrix. A thin layer of silt to silty clay exists from 65 to 70 feet. From 70 to 80 feet a well sorted medium grained sand exists. The site is situated within the SW 1/4, SW 1/4 of the NW 1/4 of Section 8, T30S/R28E, MDB&M. Based on information contained within the Kern County Water Agency Water Supply Report. 19911 depth to groundwater is approximately 190 feet. This report also indicates shallow perched water less than one mile south of the site. No saturated zones were observed during field activities. 7 '-' 6.0 FINDINGS On August 25, 1994, AGI advanced two (2) confirmation borings, designated as C-1 and C-2 (Exhibit 3), to 80' below surface grade. Confirmation boring C-1 was positioned between original site characterization soil boring 8-1 and vapor extraction wells VE-1 and VE-2. Confirmation ~oring C-2 was advanced to the north of C-1 between 8-2 and vapor extraction well VE-3. Field indicators of hydrocarbons (staining, petroleum odor and Flame-ionization detector (FID) readings of cuttings) showed no visible staining; however, the soil samples did exhibit a distinct ''varnish- like" old gasoline odor. Table 3 summarizes analytical results for confirmation borings C-1 and C-2 while appendix 8 contains full laboratory reports with chain of custodies.

Exhibit 4 presents a cross section through the plume indicating the previous size and the present size of the plume with concentrations of TPH-gasoline to the left of each borin'g. 7.0 DISCUSSION AND CONCLUSIONS Interpretation and risk analyses of the data collected are presented in the next sections. 7.1 Groundwater Risk The primary objective of the under ground tank regulations is protection of groundwater resources. The State of California through the Department of Health Services and the State Water Resource's Control Board developed the Leaking Underground Fuel Tank (LUFT) Manual2 to provide guidelines to regulatory agencies and other interested parties concerned with investigation, risk assessment and cleanup of underground tank related leaks. That document presents a leaching potential analysis for gasoline which evaluates those site characteristics which influence the downward migration of the fuel components BTEX and TPH(gasoline) such as; depth to groundwater, precipitation, soil lithology and the presence of BTEX and TPH values which can be left in place without threatening groundwater. Using this approach the Remediated site at Griffith Company using data collected during the confirmation borings was determined to fall into the low leaching potential categor¡. The stipulated maximum allowable TPH(gasoline) and BrTlE/X levels for the low category are 1000 ppm and 1/50/50/50 ppm, respectively (Exhibit 5). No sample encountered in the two confirmation borings exceeded these values with the maximum TPH gasoline being 85 ppm and the highest Benzene concentration being 0.021 ppm. According to the LUFT Manual, the residual hydrocarbon constituents still present at the Griffith Company site pose no threat to groundwater which is approximately at 190 feet in this vicinity. 7.2 Risks to the Surface Environment Risks to people and the surface environment from vapors migrating upward from the contaminated soil masses are also considered to be extremely low. The affected area at the former tank location is overlain by asphalt and dirt and is used as a driveway and parking area. If left in this condition, little to no risk to human receptors would exist. The following Risk Assessment for the Surface Environment is performed in the unlikely event that a building would be placed on this vacant area. 9 ;. An effort has been made to evaluate health risks due to exposure to benzene volatilizing from the soil and entering a fictitious building from the plume. Benzene was used because of its high volatility and known carcinogenic properties, it is considered to pose the greatest health risks. The highest concentration reported from the confirmation borings was 0.027 ppm which was detected at a depth of 45 feet in boring C-1. This value was used in the calculations. Laboratory determined values for soil properties required for the analysis are not available. Assuming a sandy unconsolidated sediment type with a low moisture content, the following parameters were estimated: Porosity .35 Bulk Density 2.0 Moisture Content .15 The approach used for the risk assessment is based in part on the methods and logic presented in the California Site Mitigation Tree Manual3 and a report by Chemrisk4 submitted to the Orange County Health Care Agency and made available as an example of a state of the art risk assessment. The steps followed and conclusions of this analysis are outlined below. A more complete discussion and the calculations are included in Appendix F. The first step in the risk evaluation process is the calculation of the steady state flux of benzene through the soil matrix assuming a non-diminishing source at some distance below the ground level. This determination requires a knowledge of benzene's coefficients of diffusion in air and through the soil as well as the vapor phase concentration of the compound at the source. Knowing the vapor phase flux through the soil, the volume of air within the building, a ventilation rate and assuming a leakage rate through a structure's foundation, a benzene vapor concentration within a building can be predicted. Then, taking a worst case scenario of a person working their entire 45 year occupational lifetime at the business, a lifetime average daily dose (LADD) received can be derived. Values of indoor vapor concentrations and LADDs can be compared to regulatory guidelines to evaluate degree of exposure and risks. In this instance, the indoor concentlation of benzene was calculated to be 5.0 X 10-9 mg/m3. The Department of Health Services Applied Action Level for benzene in ambient air is 3.2 X 10-3 mg/m3. The air concentration for lifetime cancer risk due to benzene exposure 6.6 X 104 mg/m3 can also be used. Based on an individual who worked at the site for 45 years, a LADD of 3.14 X 10-10 mglkg-day was calculated. This result can be compared to 3.0 X 10-4 mglkg·day which is considered to. result in a 1 and 100,000 excess cancer risk under DHS Proposition 65 guidelines. In all cases, calculated values are well below estabiished guidelines. 10 The potential for carcinogenic health effects can also be evaluated by multiplying the lifetime benzene exposure (inhaled volume times concentration) with an "adjusted potency factor" (USEPA)5 to derive a carcinogenic risk associated with a specific exposure to benzene. In general, regulatory agencies have found that a risk in excess of 1 and 1 million is acceptable. In some instances risks of 1 in 100,000 are used in setting environmental standards. At Griffrth Company a risk of 9.2 X 10-12 was derived, well below the 1 in 1,000,000 criteria. In conclusion, based on this risk assessment, no significant health hazards related to the gasoline contamination at the Griffith Company site are believed to exist. 8.0 REFERENCES 1.

APPENDIX C RISK ASSESSMENT FOR BENZENE AT GRIFFITH COMPANY STEADY STATE VAPOR FLUX The first step in determining the benzene exposure to occupants is the calculation of the rate of emission of the chemical from the soil. This rate is influenced by such factors as the degree of partitioning of benzene between vapor, soluble and non- aqueous phases, the rate and degree of movement of the various phases through the soil, soil properties, and environmental factors such as temperature, moisture and surface conditions. The general approach used, is to take the dominant transport mechanism, in this case vapor diffusion, and model the process. The model used is based on one developed to predict emissions from landfills by Thibodeaux and Hwang6. It assumes steady-state fluxes for a non-diminishing source at a specific depth below the ground surface. The applicable equations are: F = Cv Os H Where: F= Steady-state flux through a soil matrix from a non-diminishing source - mg.m2-day Vapor phase concentration of benzene at the source - mg/m3 Vapor phase diffusion coefficient through soil - m2/day Depth below ground surface of the contamination - 45 ft (14.7 m) Cv= Ds= H= Cv = x P M w RT Where: x= p= T= Mw= R= Mole fraction of benzene in the free liquid hydrocarbon phase. It is assumed to be approximately equal to the weight fraction of benzene in residual 0.027 ppm benzene/58 ppm TPH. The TPH value is the concentration at 45 ft. ;Jure benzene vapor pressure (atm) at temperature T - 0.10 atm Temperature (OK) - 298 OK Molecular weight of benzene - mg/mole - 78000 Universal gas constant - 8.2 X 10-5 m3 -atm/mole-oK 0.027 Cv = 58 (0.10)(78000) = 148.41 mg/m (8.21 X 10-5)(298) 1 ..,: ,)II ). The following equations are derived from Millington -Quirk7. J _ (Da)(a3,33) Ds - T2 a = E-MB Where: Da= Diffusion coefficient of benzene in air - = 0.71 m2/day. This value is calculated after Fuller et al8 Soil air content Soil moisture content - 0.15 Porosity - 0.35 Soil bulk density - 2.0 Porosity -0.35 a= M= E= B= T= a = E-MB = 0.35 - (0.15)(2) = 0.05 (0.71 )(.053.33) -5 2 D s = = 9.4 X 10m Iday .35 Substituting Cv. Ds and H into the equation for steady-state flux: F = Cv Ds H -5 = (141.41)(9.4 X 10 )~.4X 10-4 mg/m2-day 14.7 BENZENE CONCENTRATION IN INDOOR AIR Knowing the vapor flux through the soil. an estimate can be made of the concentration of benzene in the indoor air of the overlying building which contains a volume of approximately 8600 ft3 (244 m3). Benzene reaching the surface under the structure may enter the building through openings in the floor, for example, cracks, joints and loose fitting pipes. The ratio of leakage to total floor area in the average California home is 2 - 10 cm2/m2 of floor area (Grimsrud et al )9. Commercial buildings built on concrete slabs would experience less leakage than residences with crawl spaces. therefore. the lower value of 2 cm2/m2 is used in this analysis. The ventilation rate for the building is based on studies of Fisk et al1o. They estimated that the average air exchange rate for residences at 0.5 - 0.9 air changes per hour. The most conservative low end value 0.5 is used. A retail business with numerous .¿ . .. "customers entering and leaving and equipped with modern ventilation systems would experience much higher exchange rates. The concentration of benzene in the indoor air is predicted by the equation: FA Cb =- Q Where: Cb= F= Indoor air concentration of benzene due to volatilization from the soil - mg/m3 Vapor flux through openings in the foundation - mg/m2- hr 9.4 X 10-4 mg/m2-day X 1 day/24 hr = 3.95 X 10-5 mg/m2-hr Leakage area = 2 cm2/m2 =0.0002 m2 openings/m2 floor area X 100 m2 floor area = 2.0 X 10-2 m2 Ventilation rate in building - m3/hr = 0.5 exchange rate/hr X 304 m3 building volume = 152 m3/hr A= Q= -4 -2 9 Cb = (3.95 X 10 ) (2.0 X 10 ) = 5.0 X 10· mg/m3 152 RISK BY EXPOSURE In order to estimate the health risks associated with exposure to benzene, a very conservative approach was used based on a individual working at the business for an entire occupational lifetime of 45 years, 5 days a week and 50 weeks a year with an inhalation rate of 10 m3/hour. Total lifetime inhaled volume = 1.13 X 105 m3 Average daily volume = 4.4 m3/day Exposure is the product of contaminant concentration (Cb) and the air volume breathed calculated by the following equation: LADD = Cb AS Bw ~,.c.... f Where: LADD = Cb= A= B= Bw= Lifetime Average Daily Dose - mg/kg-day Concentration of benzene in air = 5.0 X 10-9 mg/m3 Inhalation bioavailability (fraction of benzene inhaled) - 100% Average daily volume inhaled = 4.4 m3/day Body weight = 70 kg LADD = (5.0 X 10 -9)(1 )(4.4) = 3.14 X 10.10 mglkg-day 70 The carcinogenic risk associated with a specific exposure can be estimated by the following: R=P'E Where: R= P'~ E= Risk associated with a specific exposure Benzene adjusted potency factor [mgllifetime exposure]-1 = 1.63 X 10-8 per USEPA 1988 - derived from epidemological studies on cancer induced leukemia. Exposure = inhaled volume M3 X concentration R = (1.63 X 10.8)(1.13 X 105)(5.0 X 10.9) = 9.2 X 10.12 //~:ì., /1 ,!;!,Æ (0}3 EO.:iCLE..nc£..:iy ..:....,/ nC$ !,." Groundwater Scientists · Environmental Consµltants January 26, 1993 Kern County Environmental Health Services Department 2700 "M" Street, Suite 300 Bakersfield, California 93301 ATTN: Mr. Brian Pitts RE: Griffith Company - Vapor Extraction System Status Report On November 6, 1993, the I.C. Engine Vapor Extraction System (VES) was moved onto the Griffith Company site, located at 1898 South Union Avenue in Bakersfield, California, to begin the remediation program. The unit was inspected on a daily basis and system conditions were logged onto a VES Monitoring Sheet. The readings consisted of the status of various system components and the measurement of hydrocarbon emissions at four (4) sample points. Copies of the VES monitoring sheets are enclosed for your review. Hydrocarbon emissions were measured using a Photo-ionization detector (PI D). A tabular listing of the PID readings obtained on the inspection dates is enclosed. Also enclosed for your review is a copy of the Authority to Construct Permit issued by the San Joaquin Valley Unified Air Pollution Control District on October 6, 1992. On January 11, 1993 the unit was removed from the Griffith site after 500 hours of operation and returned to the Pence site to resume operations there. Hydrocarbon emissions, as measured by the PID, had an initial high level at startup, but dropped rapidly as site conditions stabilized. The hydrocarbon emissions now fluctuate over a fairly consistent range of values depending on the percentage of natural gas versus extracted vapor effluent being burned by the I.C. Engine. The unit will return to the Griffith site after 500 hours of operation at the Pence site. If you have any questions regarding this matter please feel free to contact us at (805) 328-0962.

Union Avenue, Bakersfield, California. 1.1 PURPOSE The soil remediation described in this workplan has the following objectives: * Remove volatile fuel hydrocarbons from the soil using an Internal Combustion Engine vapor extraction system. 1.2 SCOPE OF SERVICES The scope of services describes in this workplan include: * Installation of vapor extraction system to include an internal combustion engine; * Permitting, operation, monitoring and maintenance of a vapor extraction system manifolded to the wells; * Confirmation boring to assess the effectiveness and signify an endpoint to remedia tion; * Preparation of a report summarizing methods and results of the soil remedia tion. 1.3 SCHEDULE AquaGeosciences, Inc. anticipates beginning work described in this workplan within one week upon approval from both the County and the Client. Installation of the vapor extraction/inlet wells in the soil borings can be completed in approximately 3 working days. Pending authorization to construct and permission to operate the VES by the Kern County Air Pollution Control District, AquaGeosciences anticipates construction and installation of the VES inclµding all associated piping and manifolding within one month from the approval of the workplan. Upon completion of the remediation, AquaGeosciences, Inc. will issue a Final Report of Findings. 2.0 BACKGROUND The site is located at 1898 So. Union Avenue, Bakersfield, California as shown on Exhibit 1. 3 of 1 5 .. -; " . 2.1 FACILITY DESCRIPTION The property is currently occupied and is currently operating as the Griffith Company. The facility consists of an office building, equipment yard and maintenance bays. Formerly located at the site were three underground fuel storage tanks, two fuel dispensers and appurtenant piping (Exhibit 2). 2.2 PROJECT HISTORY In January, 1991, MP Vacuum Service Company removed one (1) 8,000 gallon diesel underground storage tank, one (1) 8,000 gallon gasoline underground storage tank, one (1) 500 gallon gasoline underground storage tank and two fuel dispensers with the associated product lines. Soil samples were collected from beneath each tank, dispensers and the product lines at 2 and 6 foot depths. The samples were submitted to SMC Laboratories, Inc., a State Certified Laboratory for the specified analysis. The samples were analyzed for Total Petroleum Hydrocarbons (TPH) as diesel, gasoline and volatile aromatics (BTEX). The laboratory reported concentrations of TPH as gasoline beneath the former 8,000 gallon gasoline tank and the gas and diesel product lines. The concentrations in the vicinity of the east gasoline tank were reported as 5400 ppm at 2 feet and 5000 ppm at 6 feet. BTEX was also detected and increased with depth. The concentrations detected under the gasoline and diesel product lines were 420 ppm at 2 feet and 340 ppm at 6 feet beneath the gas line and 6.2 ppm at 2 feet and 300 ppm at 6 feet bene~th the diesel line. Minimal concentrations of BTEX was detected. Concentrations of TPH as diesel was detected beneath the east end of the diesel tank at 2700 ppm at 2 feet which increased to 3700 ppm at 6 feet. Concentrations of BTEX were detected and increased with depth. Total Petroleum Hydrocarbons were not detected beneath the former location of the 500 gallon gasoline tank, the west end of the 8,000 gallon diesel tank and the gasoline and diesel dispensers. On the basis of the laboratory analysis, The Kern County Environmental Health Services Department requested that a characterization be conducted at the site to assess the extent of contamination. Griffith Company contracted with BSK & Associates to perform a site characterization. BSK & Associates conducted the investigation and found gasoline impacted soil extending to a depth of approximately 75 feet and laterally distributed in a radial pattern centered about the former 8,000 gallon gasoline tank. Concentrations of gasoline ranged from 52,000 ppm at 50 feet (B-3) to 18,000 ppm at 60 feet (B-2) with 8,700 ppm at 20 feet, 27,000 at 40 feet, 17,000 ppm at 55 feet to 540 ppm at 60 feet (B-1). These findings were presented in BSK & Associates report dated May 15, 1991. In the report, BSK & Associates investigated several remedial options including: No action, excavation and disposal or in-situ vapor extraction. 4 of 1 5 ..- ~; .. This previous assessment work did not delineate the lateral limits of the plume to the north and west. This additional work will be completed as part of the initial stages of the remediation. Six (6) borings (VE-I, VE-2, VE-3, VI-I, VI-2 and VI-3) will be advanced to complete this assessment. These borings will then be completed as vapor extraction/inlet wells with the screened intervals and depths selected based upon field screening of the samples. Well locations and descriptions are given below in section 3.1. A summary of analytical results may be found in Appendix B. 3.0 WORKPLAN AquaGeosciences, Inc. plans to install an internal combustion engine vapor extraction system at this site. Using vapor extraction/inlet wells, AquaGeosciences, Inc. will manifold these wells to the vapor extraction system. A treatability study will be performed to confirm the suitability of the chosen remedial technology as well as determining the effective radius of influence. Additionally, the effectiveness of the remediation will be confirmed by advancing soil borings through the contaminant plume region. 3.1 VAPOR EXTRACTION/INLET WELL LOCATIONS AND DEPTHS Exhibit 3 shows the locations of the vapor extraction/inlet wells as well as locations of prior borings. The locations, depths, and screened intervals were chosen to provide lateral and vertical coverage of the impacted plume as interpreted from previous assessment data. In general, the vadose plume approximates a teardrop shape beginning at approximately 12 feet below grade and extending to a depth of 75 feet below grade. As indicated by the cross-sections included as Appendix C, the plume begins to spread laterally reaching a maximum radius of nearly 30 feet (NOTE: this is based upon the extreme boundary of the plume. ie. Non-Detect analytical results.). The region of this plume requiring remediation is estimated to approximate a right cylinder with a radius of 30 feet and a height of 75 feet. Wells VE-I, VE-2, and VE-3 will be placed vyithin the perimeter of the plume and screened as follows. In the shallow zone of the plume ,VE-lwill be screened from 10 to 40 feet below grade. VE-2 and VE-3 will be screened across the deep portion of the plume from 35 to 75 feet below grade. The three inlet wells (VI-I, VI-2 and VI-3) will be completed to a total depth of 75 feet and screened from 10-75 feet. Detail drawings for wells VE-l, VE-2, VE-3, VI-I, VI-2 and VI-3 are included as Exhibits 4 through 7. Locations of the wells and their relationships to the contaminant plume are indicated on Exhibit 3-Detail Map. 5 of 1 5 " ..'0 '5 3.2 VAPOR EXTRACTION/INLET WELL CONSTRUCTION METHODS Casing of the extraction/inlet wells will consist of Schedule 40 factory slotted (0.02 inch), four inch diameter, flush threaded PVC pipe with a bottom cap. The slotted section will extend across the impacted zone, and blank Schedule 40 PVC pipe will complete the VES well to surface. The annular filter pack consists of Number 3 Lonestar sand. It will be placed from total depth to three feet above the slotted interval. Three feet of bentonite pellets will be placed above the sand to form a seal. Cement grout will extend from the bentonite seal to the surface. Traffic rated well boxes will be installed flush with the ground surface. The vapor extraction/inlet wells will be manifolded using a 4" diameter Schedule 40 PVC pipe one foot below the surface connected to the VES intake manifold. Alternatively, plumbing and manifolding can be placed on the surface and can be constructed of either PVC or flexible vacuum hose. Each wellhead will be equipped to function as either an extraction or inlet well via a gate valve system. This allows optimum flexibility for aerating and extracting the gasoline from the soil. The soil borings will be drilled adjacent to the probable release point. The proposed completion intervals have been selected to screen across intervals of similar lithology and permeability while providing complete coverage across the impacted interval. See Section 6.0 for discussion of boring methods, soil sampling, field screening and chemical analy.tical methods. 3.3 WELL HEAD DESIGN AND VALVE CONFIGURA nON Each of the six (6) wells will be equipped with a 2-inch globe valve to control flow in each of these wells. Flow control on the air inlet wells will help balance anisotropic flow in the vadose zone due to lithology as measured during the feasibility study. The well to be placed on vacuum will be manifolded to the IC Engine YES with two (2) inch diameter flex vacuum hose equipped with earn lock fittings. 3.4 VACUUM MEASUREMENT AND RADIUS OF INFLUENCE To estimate the radius of influence for the well configuration we will conduct a field feasibility test. The field feasibility test will consist of applying a vacuum to each well in rotation. A vacuum pressure gauge will be placed on each of the five (5) remaining vapor extraction/inlet wells in turn to measure the vacuum drawdown at each location. The vacuum pressure gauge to be employed will be capable of detecting pressure changes as little as D.l-inch of water.Vacuum drawdown will be recorded from each inlet well and will be plotted against distance. The distance- drawdown curves thus generated will yield ~e empirical data necessary to estimate whether the well configuration will provide sufficient lateral coverage to effectively remediate the impacted soil. The radius of influence testing will also yield information regarding anisotropic flow in the vadose zone which will be used to determine the inlet well valve configura tion. 6 of 15 ;; ~ ~ 4.0 TREATMENT OBJECTIVES The objective of this remediation is to reduce the concentration of contaminants in vadose zones to levels which are consistent with LUFT manual guidelines and Kern County Environmental Health Services Division requirements. The proposed remedial objectives for this site are: TPH as gasoline 100 ppm, benzene 0.3 ppm, toluene 0.3 ppm, ethylbenzene 1.0 ppm, and.total xylenes 1.0 ppm. 5.0 EVALUATION OF MITIGATION The mitigation of the site will proceed until gasoline vapor concentrations in the inlet air stream have been reduced to 10 ppm, as determined by PID/FID field screening. The machine will be shut down for a period of approximately one week to allow any residual vapors to accumulate and will then be restarted. This process will be repeated until the concentration of gasoline vapors in the inlet air stream remain below 10 ppm after restarting the YES system. A soil boring will then be advanced through the center of the former contaminant plume where highest concentrations were found. The confirmation soil boring will be advanced to a depth of 75 feet. Soil samples will be collected at every five foot interval from 15 to 75 feet and selected representative soil samples will be submitted for chemical analysis. The vapor extraction system and operation will be monitored according to the monitoring/ testing program as required by the Kern County Air Pollution Control District in the Authority to Construct. DetaHed field monitoring logs will be kept and monthly status reports will be generated and submitted to our client. The reports will detail equipment operations, influent/ effluent concentrations and will document the progress of the remediation. 6.0 CONFIRMA TION BORING, SOIL SAMPLING, FIELD SCREENING AND CHEMICAL ANALYTICAL METHODS The following sections will detail the methods to be employed for conducting further assessment installating vapor extraction/inlet wells and confirmation sampling at the end of remedial activities. 6.1 BORING METHODS The confirmation soil boring will be advanced using a Mobile Drill B-53 Rig, or equivalent equipped, with 6 5/8 inch diameter or larger hollow stem continuous flight augers in accordance with ASTM Method 01452-80 for soil investigations and sampling by auger borings. The auger and hammer will be steam cleaned prior to drilling each boring. 7 of 1 5 ç . $ The lithology and other pertinent data will be recorded on a field boring log in accordance with ASTM Method D2488-84 for visual description and identification of soils. Borings will be logged by or under the direct supervision of a California Registered Geologist. Cuttings and other spoil from the borings will be placed back in the borehole if field screening indicates clean samples. If contaminants are detected from field screening, the cuttings will be stored in D.O.T. approved 55-gallon drums pending analysis. 6.2 SOIL SAMPLING Soil samples will be collected through the auger in 2-inch brass sleeves driven in a split spoon sampler by a 140 pound hammer with a 30-inch drop in accordance with ASTM Methods D1586-84 for split-barrel sampling of soil and D1587-83 for thin walled tube sampling of soils. The brass sleeves and sampler will be steam cleaned prior to each use. Soil samples will be driven at five foot intervals. The blow counts, recovery, and lithology will be recorded on field logs. Lithology will be described in accordance with the Unified Soil Classification System (USCS). One brass sleeve with soil from each interval will be capped, sealed, and labeled in accordance with EP A protocols, recorded on a Chain-of-Custody form, placed in a cooler at 4° centigrade or less, and transported to a California Certified Laboratory with the Chain-of-Custody for the specified analyses. Selected samples will be analyzed and the other samples will be held no more than fourteen days for further analyses if necessary. 6.3 FIELD SCREENING Soil samples will be collected using three six-inch brass tubes installed inside a split spoon sampler. The middle sample tube will be immediately capped with a teflon liner separating the soil from the lid, and stored in an iced cooler. The bottom tube will be used for lithologic description, and the top tube will be used for field screening. The material from the top tube will be placed in a mason jar to approximately 50 percent capacity, shaken, é,ind stored for a period of 15 minutes. A standard headspace reading will be collected at this time and noted on the boring log. Field screening will be conducted using a Foxboro 128 GC/FID calibrated to a methane standard. 6.4 SOIL ANALYSIS The soil samples will be analyzed by Mobile Labs, Inc., a California State Certified Laboratory in accordance with state guidelines and EP A protocols. The samples will be analyzed for Total Petroleum Hydrocarbons as gasoline, benzene, toluene, xylene, and ethylbenzene (BTXE) using the D.O.H.S. L.U.F.T. Method and EPA Method 8020, respectively. 8 of 15 ;: ~ 7.0 DECOMMISSIONING OF REMEDIATION EQUIPMENT After remediation is complete, the vapor extraction wells and the vapor extraction system will be dismantled. All of the inlet/ extraction wells will be backfilled with cement grout. No surface evidence of remedial activities will be present following decommissioning. 8.0 FINAL REPORT When the remediation process is deemed complete a final report will be submitted to the Client. This report will include all remedial field operations, analytical data, and final conclusions. After review by the Client the report will be submitted to Kern County Environmental Health Services Department. The final report will be certified by a California Registered Geologist and/ or a Registered Chemical Engineer. 9.0 QUALITY ASSURANCE PLAN This section describes field and analytical quality-assurance procedures to be followed during the remediation. 9.1 SAMPLE COLLECTION AND HANDLING PROTOCOL Proper sample collection and handling are essential to assure quality of data obtained from a sample. Each sample therefore will be collected in a brass tube, preserved correctly for the intended analysis and stored for no longer than the permissible holding time prior to analysis. Protocol to be applied in this project is described in Section 6.2. 9.2 SAMPLE IDENTIFICATION AND CHAIN OF CUSTODY PROTOCOL Sample identification and Chain of Custody procedures are designed to assure sample quality and to document sample possession from the time it is collected to the time of its ultimate disposal. The container for each sample submitted for analysis will have a label affixed with the identifying number or the number will be inscribed directly on the container if feasible. The analytical laboratory will assign a separate sample number unique to that sample for internal sample coordination and identification. A description of the sample, including the sample number and other pertinent information regarding its collection and/ or geologic significance will be written in field notes and/ or a geologic boring log prepared by the site geologist. These field documents will be kept in a permanent project file. All samples will be analyzed by a State Certified Laboratory for the analyses requested. 9 of 1 5 .; · A properly completed Chain of Custody document will be submitted to the analytical laboratory along with the samples. The laboratory's assigned number will be properly entered on the form. A quality control officer at the lab will verify the integrity of the samples submitted, proper sample volume, correctness of containers used and properly executed Chain of Custody document. Pertinent information will be entered into a logbook kept by the laboratory. 9.3 ANALYTICAL QUALITY ASSURANCE In addition to routine calibration of analytici:1l instruments with standards and blanks, the analyst is required to run duplicates and spikes on 10 percent of analyses to assure an added measure of reliability and precision. Accuracy is verified through the following: 1. U.S. EP A and State certification of results; 2. Participation in inter-laboratory round robin programs; 3. "Blind" samples are submitted for analysis by the quality control officer on a weekly basis. These are prepared from National Bureau of Standards specifications of EP A reference standards; 4. Verification of results with an alternative method. 10.0 SITE SAFETY PLAN Appendix A contains a Site Safety Plan which complies with the Worker Right to Know Regulations and CAC Title 26. 1 0 of 1 5 ,. ~ - U"·_.

SITE SAFETY PLAN INTRODUCTION: A Site Safety Plan (SSP) has been designed to address safety provisions needed during the site soil remediation. Its purpose is to provide established procedures to protect all on-site personnel from direct skin contact, inhalation, or ingestion of potentially hazardous materials that may be encountered at the site. The SSP establishes personnel responsibilities, personal protective equipment standards decontamination procedures, and emergency action plans. AquaGeosciences, Inc. seeks to enter property described above for the purpose of installing a vapor extraction system consisting of four (4) vapor extraction/inlet wells, manifolding, vapor extraction trailer and internal combustion engine unit. Drilling equipment will be brought to the site and operated by a subcontractor: Mel ton Drilling 1701 Downing Avenue Bakersfield, California 93308 C-57 License Number 508270 The SSP describes means for protecting all on-site personnel from deleterious contamination or personal injury while conducting on-site activities. As described below we will meet all requirements promulgated by the California Department of Health Services. SITE BACKGROUND This property is currently operating as the Griffith Company.. In January, 1991 two (2) 8,000 gallon underground storage tanks, one diesel, one gasoline, one (1) 500 gallon underground gasoline storage tank, two fuel dispensers and associated product lines were removed. Subsequently, a site characterization has been performed assessing the extent of the contaminant plume. RESPONSIBILITY OF KEY PERSONNEL: All personnel on-site will have assigned responsibilities. Mr. Phil Goalwin, KG. of AquaGeosciences, Ine. will serve as Project Manager and On-Site Geologist. Mr. Thomas Reeves will serve as Project Engineer. He will also serve as Site Safety Officer (550). As 550, Mr. Reeves will assure that on-site personnel have received a copy of SSP. Personnel will be required to document their full understanding of the SSP before admission to the site. Compliance with the SSP will be monitored at all times by the 550. Appropriate personal protective equipment, listed below, will be 11 of 1 5 '\'< ~ , used as necessary. Mr. Goalwin will conduct a training session to assure that all are aware of safe work practices. In the training session, personnel will be made aware of hazards at the site and will utilize Material Safety Data Sheets for information on compounds. The SSO will also be responsible for keeping field notes, collecting and securing samples, and assuring sample integrity by adherence to Chain-of-Custody protocol. On-site employees will take reasonable precautions to avoid unforeseen hazards. After documenting understanding of the SSP, each on-site employee will be responsible for strict adherence to all points contained herein. Any deviation observed will be reported to the SSO and corrected. On-site employees are held responsible to perform only those tasks for which they believe they are qualified. Provisions of this SSP are mandatory and personnel associated with on-site activities will adhere strictly hereto. JOB HAZARD ANALYSIS: Hazards likely to be encountered on-site include those commonly encountered when operating any mechanical equipment, such as the danger of falling objects or moving machinery. Simple precautions will reduce or eliminate ,risks associated with operating such equipment. A drilling contractor has been employed to deliver and operate all drilling equipment. Qualified personnel only will have any contact with this equipment. All on-site personnel, including the drilling contractor and his employees, are required to wear hard hats when in close proximity to drilling equipment. Latex gloves will be worn by persons collected or handling samples to prevent exposure to contaminants. Gloves will be changed between samples, and used ones discarded, to avoid cross-contamination. Proper respiratory equipment will be worn if vapor contamination levels on-site exceed action levels as determined using PID. Action levels requiring respiratory apparatus will be 5 ppm, in the breathing space. Furthermore, no on-site smoking, open flame, or sparks will be permitted in order to prevent accidental ignition. RISK ASSESSMENT SUMMARY: Exposure to chemicals anticipated on-site include gasoline, benzene, toluene, and xylene (BTX). These chemicals represent a hazard because they are moderately to extremely toxic and most are highly flammable. 12 of 15 ~ Threshold Limit Values (TL V's), Short Term Exposure Limits (STEL's), and Toxicity levels (LD50, oral-rat), all in mg/kg (ppm), are listed below: COMPOUND TLV STEL TOXICITY Gasoline 200 300 ------ Benzene 10 25 4894 Toluene 100 50 5000 Xylene 100 150 4300 Benzene is considered an extreme cancer hazard. EXPOSURE MONITORING PLAN: A Photo-Ionization Detector (PID) or a Flame-Ionizing Detector (FID) will be used to monitor vapor concentrations around site. Should concentrations exceed TL V's, protective measures will be taken. Passive dosimeter badges will be placed in downwind locations if PID reading indicate high levels of volatile organics in the breathing space. PERSONAL PROTECTIVE EQUIPMENT: Personnel on-site will have access to respirators with organic vapor cartridges. Replacement cartridges will be available on-site as needed. When handling samples, the on-site geologist will wear latex gloves. Hard hats will be worn by all personnel on-site when in proximity of drilling equipment. WORK ZONES AND SECURITY MEASURES: Access to the site will be restricted to authorized personnel. Fencing, a set of cones, placards, or wide yellow tape, surrounding the site will define perimeter. The Project Manager will be responsible for site s,ecurity. DECO NT AMINA TION MEASURES: Avoidance of contamination whenever possible is the best method for protection. Common sense dictates that on-site personnel avoid sitting, leaning, or placing equipment on possibly contaminated soil. All personnel will be advised to wash their hands, neck, and face with soap and water before taking a break or leaving the site. Respirators will be washed with soap and water following each day's use. Drilling and sampling equipment used will be decontaminated by steam-cleaning. Sampling equipment will be decontaminated before each sample is taken and drilling equipment will be decontaminated before each boring is commenced. 1 3 of 1 5 ,,' . ~. ~ ; GENERAL SAFE WORK PRACTICES: Drillers and other on-site personnel will be briefed each day in "tailgate" meetings as to the day's goals and equipment to be used. Anticipated contaminants and emergency procedures will be reviewed. Appropriate personal protective equipment will be put on and verified correct by SSO, including respirator fit. Drilling and sampling equipment will be steam-cleaned before being brought on- site. Split-spoon sampling equipment will be steam-cleaned before each use. Augers will be stéam-cleaned between borings. The On-Site Geologist will oversee operations and log borings in consultation with drillers. The Sample Coordinator will assure that proper protocol is used at all times in collecting and handling samples. TRAINING REQUIREMENTS: The SSO will conduct a pre-site training session which will include all points of MSDS forms, contaminant properties, warni!lg signs, health hazard data, risk for exposure, and emergency first aid. All chemicals to be covered and the SSO will assure that everyone fully understands site hazards. MEDICAL SURVEILLANCE PROGRAM: According to CPR 29, 1910.120, paragraph (f), employees who wear respirators 30 days or more during one year or who have been exposed to hazardous substances or health hazards above established permissible exposure limits are required to be monitored medically. All site personnel will be required to have had a complete chemical physical within the past year. RECORD KEEPING: Documentation will be kept on personnel exposed to contaminant hazards on the job site according to OSHA regulations. These will include documentation that employees have received training on the SSP, respiratory protection, MSDS forms, and all emergency procedures. These will be reviewed during the pre-site training meeting. Exposure records on each job will be kept for 30 years to meet requirements. Included will be names and social security number of employees, medical evaluation, on-the-job logs from entry to exit, first aid administered, visits on-site by outside persons, and personal air monitoring records. 1 4 of 1 5 i' ".. ..

Three underground fuel storage tanks, associated fuel lines and dispensers were removed from the Griffith Company facility in mid-January of 1991. The storage containers consisted of one 8,000 gallon diesel fuel tank, an adjacent 8,000 gallon gasoline tank, and an additional 500 gallon gasoline tank situated nearby. Two fuel dispensers, and two fuel lines were also removed. Tank removal and disposal was performed by MP Vacuum Service Company. Soil sampling beneath the tanks was performed by Mr. George Sweet, Environmental Contractor. Analytical testing of soil samples was conducted by SMC Laboratory. Four soil samples were collected from beneath each 8,000 gallon tank, at depths of 2 and 6 feet, from locations at each end of the containers (see Figure 2, Site Plan). Two samples were collected from depths of 2 and 6 feet below each dispenser, the 500 gallon tank, and beneath each fuel line at a location approximately midway between its respective tank and fuel dispenser. Soil samples obtained beneath the gasoline tanks, gasoline dispenser, and both fuel lines were tested for Total Petroleum Hydrocarbons - Gasoline (TPH-G), and Volatile Hydrocarbons including Benzene, Toluene, Xylenes, Ethylbenzene (BTXE), and Isopropylbenzene. Samples collected beneath the diesel tank and it's dispenser were analyzed for Total Petroleum Hydrocarbons - Diesel (TPH-D), and Volatile Hydrocarbons. Test results (Table I, Preliminary Test Results) indicate high concentrations of gasoline in samples obtained from beneath the east end of the 8,000 gallon gasoline tank, and lower concentrations in samples collected from beneath the gasoline fuel line. BSI~ & Associatð Page 2 .~ High concentrations of diesel fuel were indicated in tests performed on samples obtained beneath the diesel tank.

Griffith Company retained BSK & Associates to characterize soil contamination. BSI( & Associates í:' Page 3 {\ The workplan to perform the Site Characterization is included in our document labeled JOB B91090, dated March 29, 1991 (Appendix B). The scope of this soil contamination investigation was limited to drilling a maximum of 6 borings at the site, sampling soils for chemical analyses, and providing a report discussing our findings and recommendations concerning appropriate remediation alternatives. Prior to initiating the investigation, our workplan was reviewed and conditionally ~ approved by Mr. Michael Driggs with KCEHSD. Mr. Driggs based his approval on~1 conditions that include relocating lateral borings 5 to 10 feet closer to the tanks,than those originally proposed, and obtaining and testing soil samples from borings B-1 and B-4 at 5-foot intervals. SITE DESCRIPTION Tanks removed from the site were located about 25 feet east of the Griffith Company office building, within their parking lot. The Griffith facility comprises a fenced area of several acres which contain the office building, a repair shop, and storage space for Company equipment and machinery. Much of the site is paved with asphalt concrete. Tank excavations had been backfilled. A fill depth of about 16 feet is estimated. Underground utilities, including electrical, gas, and water service lines are situated along the east side of the Griffith office. The property is generally level. FIELD INVESTIGATION Our field investigation was performed on April 15 and 16, 1991. Five test borings were drilled to observe and sample subsurface soils for gasoline and diesel contamination. An OYM Model 580A portable photoionization detector (Pill) was used at the site to qualitatively screen soil samples for hydrocarbon contamination. Mr. Michael Driggs (KCEHSD) was present to observe much of the field drilling and sampling. Test Boring B-1 was drilled over the approximate center of the former gasoline tank emplacement to assess the vertical extent of gasoline contaminated soil. Soil samples were obtained from Boring B-1 at a depth of 20 feet and thereafter at 5-foot intervals to a depth of 75 feet where soil conditions and field instrumentation indicated non- detectable concentrations of hydrocarbon compounds. BSI( s.. Associates Page 4 " Test Borings B-2 and B-3 were drilled to assess the lateral extent of hydrocarbon contamination. Boring B-2 was located 15 feet northeast of Boring B-1. PID instrumentation indicated that soils encountered by Boring B-2 contained levels of hydrocarbon contamination. Based on conditions observed at Boring B-2, Boring B-3 was drilled 25 feet north of Boring B-1 with the objective of defining the lateral extent of hydrocarbon contamination. PID readings of Boring B-3 soils also indicated hydrocarbon contamination. Test Boring B-4 was drilled over the approximate center of the former diesel tank emplacement to assess the vertical extent of diesel contaminated soil. Based on Mr. Driggs approval at the site, soil samples were obtained at 10-foot intervals from a depth of 20 feet, to the final depth of 70 feet where soil conditions and field instrumentation indicated non-detectable concentrations of hydrocarbon contamination. Boring B-4 was situated about 13 feet south of Boring B-1. PID values, higher than those normally expected for diesel contamination, were observed in Boring B-4 soils at depths below 40 feet, indicating the potential presence of gasoline contamination. Boring B-5 was located 35 feet southeast of Boring B-1 and 22 feet from Boring B-4. Soils sampled from Boring B-5 were observed and measured with the PID to provide an indication of the lateral extent of hydrocarbon contamination. Field screening of Boring B-5 soils suggested that significant hydrocarbon contamination had not migrated significantly beyond this point. Mr. Driggs concurred that field observations provided an adequate indication of the lateral extent of hydrocarbon contamination in soils and the field investigation was terminated. SOIL SAMPLING PROTOCOL Drilling and soil sampling was performed with a truck-mounted drill rig using 8" hollow stem augers. The augers act as continuously advancing steel casings preventing test holes from caving in above the level to be sampled. Samples were obtained by lowering a 2- inch inside diameter sampler containing stainless steel liners inside the hollow stem auger and driving it into undisturbed soils. The sampler was cleaned with Liquinox, a surgical grade biodegradable detergent, and rinsed with potable water between sampling activities. The hollow stem augers were steam cleaned prior to entering the site and between borings to prevent cross- contamination. BSI( & Associates Page 5 The drill crew consisted of a driller and a helper. The field investigation was supervised by a geologist who was responsible for the preparation of field boring logs, recording of field conditions, soil sample handling and preservation, Chain-of-Custody documentation, and the field equipment cleaning process. Intact samples were collected in stainless steel liners. Liner tubes containing the samples were capped with teflon seal, then with pressure fitted plastic caps, and secured with adhesive tape. Each sample was labeled with an adhesive-backed label including boring designation, depth of sample, and initials of the individual preparing the sample. Soil samples were stored in insulated chests with "Blue Ice" and delivered for testing to BSK's State-certified Laboratories in Fresno. Laboratory analysis was performed within 14 days from the date of sampling. A Chain-of-Custody form was prepared which recorded names of the individuals collecting, transferring, and analyzing the samples. A copy of the Chain-of-Custody document is included in Appendix "A". / I "») ¿,é.. (.N~. . Dr.ilL.cuttiagsere gtockpi1ed..at.ihe_sjt~.-kov~d with pl~~tic ~heeting for eventual di~osal by the owner. The test borings were grouted with a sand/cement slurry consisting of 7 sacks of Portland cement per cubic yard. SOIL CONDITIONS Surficial soils in the vicinity of the project site are classified as Quaternary alluvium. The soils consist of alluvial fan and stream channel deposits composed of non-uniform and discontinuous lenses of fine and coarse grained sediment. Soils encountered during the field investigation consist of interbedded layers of silty sand and sand to a depth of about 64 feet. An approximately 5-foot thick clayey silt layer was observed below the sandy strata. The clayey soils were relatively soft and exhibited low plasticity. Sand underlays the clayey silt to a depth of at least 75 feet; the maximum depth of investigation. Soil cuttings and intact soil samples obtained from the test borings were observed by the site geologist for visible hydrocarbon staining and odor. The soil samples were further screened with the PID for indications of hydrocarbon contamination. Generally, diesel contaminated soils exhibited a gray stain, had lower PID values and emitted relatively stronger petroleum odors than gasoline contaminated soils. BSI( & Associates Page 6 ~, Test Hole Logs, shown in Figures 5 through 9, should be consulted for more detailed subsurface conditions, including PID values. The logs contain both factual and interpretive information. Horizontal lines, designating the interface between materials encountered, represent approximate boundaries. Transitions between soil layers may be gradual. GROUNDWATER CONDmONS The site is situated within the SW 1/4, SW 1/4 of the NW 1/4 of Section 8, T30S1R28E, MDB&M. Based on information contained within the Kern County Water Agency May 1989 Water Supply Report, published in May 1990, depth to groundwater beneath the site is reported to be about 165 feet. Shallower "perched" groundwater has not been known to be present beneath the site and was not detected in our test borings. LABORATORY ANALYTICAL TESTING Laboratory testing of soil samples was performed by the BSK & Associates' State- certified Analytical Laboratory in Fresno, California. Samples were analyzed for the presence of Total Petroleum Hydrocarbons - Gasoline (TPH-G), Total Petroleum Hydrocarbons - Diesel (TPH-D), as well as Benzene, Toluene, Total Xylene and Ethylbenzene (BTXE). Chemical tests on the soil samples were conducted in accordance with the following listed methods: Constituents Test Method TPH-G EP A 8015M TPH-D DHS GCIFID BTXE EP A 8020 Analytical test results from this assessment are included in Appendix "A" and summarized in the following table.

Measurable TPH-G concentrations were not detected in soil samples collected deeper than 65 feet. High concentrations of the more mobile aromatic constituents (Benzene, Toluene, Ethylbenzene, and Xylene isomers) were detected to a depth of at least 55 feet. Lower concentrations were detected in soil samples to 70 feet. A general indication of the radial extent of hydrocarbon contamination can be inferred on the basis of the test results at BoriÌÎg B-5. While trace amounts of contamiÍ1ation were detected at a depth of 40 feet, the radial distance of 35 fe~t to Boring B-5 may be viewed as an indication of the maximum excursion of hydrocarbon contamination in soils. This assumes that ~oil texture is uniform throughòut the depths and radial extent of investigation. Variations in soil conditions leading to some non-uniform hydrocarbon migration should invariably be expected. A 35 to 40 foot radius of hydrocarbon contamination would reach the office building to the west of the tank emplacement. Based on the results of our investigation, significant hydrocarbon contamination in soils beneath the office building is not likely. An additional boring and testing would be necessary to establish conditions beneath the building. Figures 2 and 3 illustrate the approximate vertical and lateral configuration of soils likely affected by hydrocarbon compounds. These illustrations portray an idealized f1114nd approximate outline of measurable TPH contamination in soils based on laboratory test results. Generally, lateral spreading of contamination with increased depth is indicated Regulatory agencies generally require that remedial action be taken when concentrations of hydrocarbon constituents in soils exceed maximum allowable levels. Maximum allowable levels of BTXE and TPH in soils can be estimated using the Leaching Potential Analysis outlined in the Leaking Underground Fuel Tank (LUFf) Field Manual: Guidelines For Site Assessment, Cleanup and Underground Storage Tank Closure, published by the State of California Water Resources Control Board. In the Leaching Potential Analysis procedure, the following characteristics of the site are evaluated for downward migration potential of contaminants: 1. Depth of groundwater from the soil sample. 2. Subsurface fractures. BSI( & Associates Page 9 3. Annual precipitation. 4. Man-made conduits. 5. Nearby wells and existence of coarse soil. Each characteristic is scored on a scale quantifying low (10 points), medium (9 points), or high (5 points) potential for leaching. The sum of the scores provides an appraisal of site characteristics. Based on the total score, a set of allowable levels of BTXE and TPH can be obtained Conditions at the site are listed and evaluated as follows: Site Condition Corresponding Score 1. Depth to groundwater from the bottom of the zone of contamination is at least 100 feet 10 2. No fractures in subsurface. 10 3. An annual precipitation of less than 10 inches. 10 4. No man-made conduits. 10 5. Coarse soil. 9 Total 49 Based on LUFf guidelines, native soils with a TPH-G level higher than 1000 mg/kg and TPH-D concentrations greater than 10,000 mg/kg would be considered excessive of current allowable levels. LUFf maximum levels of Benzene, Toluene, Xylene, and Ethylbenzene are 1, 50, 50, and 50 mglkg, respectively. Test results from our assessment (Table II) indicate that current TPH-G LUFf c entrati ·on levels are not exceeded in soils at de ths eater than 55 to 60 TPH-D concentrations in samp e so 0 not exceed LUFf idelines. BTXE LUFf concentratIOns are not excee e m soils greater than 65 to 70 feet. BSI( & Associates Page 10 .~ REMEDIATION Tests performed in our assessment indicate simificant concentrations (in excess of LUFf guidelines) of gasoline constituents in soils which extend from the surface to a depth of between 65 to 70 feet over a radial distance approximated to be 35 feet. This zone of contamination may contain an estimated volume of some 3600 cubic yards of soil. LUFf guidelines only serve as indications of the level of significant contamination. Final determination of cleanup levels and remediation standards are customarily set by the regulatory agency (in this case, the KCEHSD). In compliance with Kern County guidelines, practical remediation options and a "no action" alternative are addressed for this particular site. Remediation alternatives include vapor extraction "soil venting", in-situ bioremediation, and excavation. Generally, the choice of an appropriate remediation method is at the discretion of the property owner, based upon the environmental consultant's recommenqations, and contingent upon approval by the regulatory agency. In the case of the Griffith Company site, the following remediation options are considered in order of BSK & Associates suggested recommendations. NOACfION DESCRIPTION: This action, generally designated "cap and containment", would involve leaving the present contaminated soil in-place. If implemented, we would suggest that the dirt- covered ground surface in the vicinity of the removed tanks be sealed with concrete or asphalt concrete to limit surface water infiltration and subsequent leaching of contaminants. FEAsIBILITY: Concerns to be considered when weighing a IIno action" alternative include: 1) Will no action result in substantial increase of airborne contaminant emissions? 2) Will it result in contaminant discharge to underlying groundwater? 3) Will it cause known adverse effects on the environment or to human health? BS( & Associates Page 11 ~ The constituents of gasoline include highly volatile components which may transform in part to the gas-vapor phase and migrate through soil to the atmosphere. RmÜ1.sions from the buried plume of contamination, if any, would probably release slowly into the atmosphere at relatively low concentrations. Should the plume be disturbed, for example during future construction or excavation on the site, emission release may be higher. It is unknown whether the existing contaminant plume would continue its downward migration. The sources of leakage have been removed Depth to groundwater beneath the base of the contaminant plume (at least 100 feet), minimal precipitation in the region and other factors evaluated in the Leaching Potential Analysis indicate that the potential risk of groundwater impact is low. IlEAL TH RISK: Health risks regarding potentially hazardous waste are normally considered in acute (short term) and chronic (long term) effects. The short term risks appear to be low. The subsurface contamination has likely existed in its present state for a number of years without a known report of adverse health effects resulting from it. Determination of the occurrence of health effects due to chronic exposure is difficult and generally requires additional investigation regarding the toxicologic properties of the contaminants. A thorough environmental risk assessment would conform to standards of practice of a survey conducted by a Certified Industrial Hygienist. This report is not intended to take the place of an industrial hygiene survey addressing long term health risks associated with leaving the contaminant plume in place. However, the primary health risk associated with subusurface hydrocarbon contamination is leachate migration to groundwater and subsequent contamination of potable water sources. We, have concluded that the risk of leachate migration to groundwater is low. COST ANALYSIS: Minimal costs would be incurred with "no action." SOIL VENTING DESCRIPTION: Soil venting or vapor extraction may be accomplished at the site by placing vapor extraction wells throughout the zone of contamination. The casings are connected to an air pump which then evacuates soil gases into an appropriate filtration system. Venting continues until contaminant concentrations are reduced to levels acceptable to regulatory agencies. BSI( & Associates Page 12 FEAsIBILITY: Volatile hydrocarbons reduction by this method is feasible. The time necessary to "clean" the site would depend on soil permeabilities, number of extraction wells, types of equipment, and clean-up levels established by regulatory agencies. Soil sampling would be necessary throughout the program to monitor residual levels of contamination until they meet regulatory requirements. This option would also require approval by the local Air Quality District prior to implementation. Soil venting of diesel-contaminated soils to acceptable levels may prove difficult based on that fuel's lower volatility as compared to gasoline. Some excavation of diesel contaminated soils would likely be necessary. HEALTH RISK: Minimal exposure risk if extracted vapors are controlled, captured and properly disposed COST ANALYSIS: Depending on the extraction systems used, a soil venting remediation program could range in cost from $50 to $80 per cubic yard. Costs include excavation of diesel soils, installation of extraction wells, and rental and operation of typical soil venting equipment. For this site, remediation costs could range from $180,000 to $300,000. Specialized remediation firms should be consulted for site-specific costs. IN-SITU BIOREMEDIATION DESCRIPTION: Bioremediation is an effective technology for hydrocarbon cleanup in some site-specific instances. In this case, bacteria designed to break down hydrocarbon compounds would be introduced through a number of injection wells until contaminant concentrations are reduced to acceptable levels. FEAsIBILITY: Bioremediation of hydrocarbon contaminated soils has gained limited complete acceptance by regulatory agencies. State and local permitting, necessary for this type of remediation, may prove difficult. BSI( & Associates Page 13 The time necessary to remedy the site using in-situ bioremediation would depend on subsurface soil conditions, hydrocarbon concentrations, types of introduced bacteria, and clean-up levels established by regulatory agencies. Pre-remediation pilot studies may be needed to test the effectiveness of proposed bacteria on the specific contaminant. Soil sampling would be necessary throughout the program to monitor residual levels of contamination until they meet regulatory requirements. IlEALm RISK: Minimal health risks would be encountered due to limited exposure to the subsurface contaminant plume. COST ANALYSIS: An in-situ bioremediation program may range from $30 to $60 per cubic yard of contaminated soil. Specialized bioremediation firms should be consulted for site-specific costs. EXCAVATION DESCRIPTION: Excavation of the contaminated soil would require a large diameter flight auger or bucket auger drill rig. A number of deep columns of soil would be removed throughout the zone of contamination and backfilled with a cement slurry mix. Excavated soil is disposed at a landfill, treated with bacteria, or allowed to aerate on the surface. A sloped excavation utilizing a clam-shell is not considered feasible. The lateral dimensions of the excavation to remove this much material would undermine the Facility office building and would prove unacceptable. FEAsIBILI1Y: Space is required at the site to set up augering, cementing, and trucking equipment Because of the relative cohesionless nature of the soils, temporary casings may be required to stabilize the augered excavations. Conditions associated with sloped excavations are avoided with the auger method. Vapor emissions are reduced. Safety around the site is increased with the absence of a large open pit. Shoring may be eliminated. Over-excavation is not required. Backfilling and compaction is minimized. BSI( & Associates - --..:,.~ ~, Page 14 Based on test results, the potential for significant hydrocarbon contamination beneath the office building is low. If significant concentrations of hydrocarbons requiring remediation are present beneath the building then, excavation of contaminated soils may not be feasible due to the possibility of undermining the structure. IlEAL TH RISKS: Reduced vapor emissions utilizing an auger would limit worker exposure risks. COST ANALYSIS: Typical excavation costs may range from $10 to $20 per cubic yard of removed material. Concrete backfill may cost $50 per cubic yard Engineering, permitting, and other miscellaneous costs could add an additional $25,000 to $50,000 to the project. Treatment costs, estimated at $50 to $100 per yard of the excavated soil, would depend on the method used For this particular site, costs for excavation and treatment of contaminated soils would depend on the amount of material required for removal by the regulatory agency. Assuming that 3600 cubic yards of contaminated soil is remediated; excavation and treatment may exceed $500,000. LIMITATIONS Findings and conclusions presented in this report are based on data obtained from the test borings shown on the Site Plan (Figure 1), and results of analytical testing of soil samples. The report does not reflect variations which may exist between borings and sampling points. These variations cannot be anticipated nor may they be entirely accounted for in spite of exhaustive additional testing. Opinions expressed regarding health risks concerning the subsurface soil contamination are intended to be an overview of potential health problems that may be encountered This report is not intended to take the place of a thorough risk assessment which should conform to standards of practice of an industrial hygiene survey conducted by a Certified Industrial Hygienist. This report has been prepared in accordance with generally accepted engineering practices for the area, based on the guidelines of local and State jurisdictions.

We are providing this Workplan and an accompanying Health & Safety Plan for County approval prior to commencing the field investigation. PROJECf INFORMATION The Griffith Company facility is located at 1898 South Union Avenue, situated near the northeast corner of South Union Avenue and Watts Drive in Bakersfield, California (See Figure 1, Vicinity Map). Three underground fuel storage tanks, associated fuel lines and dispensers were removed from the Griffith Company facility in mid-January of 1991. The storage containers consisted of one 8,000 gallon diesel fuel tank, and one 8,000 gallon tank and one 500 gallon tank used for gasoline. Two fuel dispensers, and two fuel lines were also removed. Tank removal and disposal were provided by MP Vacuum Service Company. Soil sampling beneath the tanks was performed by Mr. George Sweet, Environmental Contractor. Analytical testing of soil samples was conducted by SMC Laboratory. _ Fresno, California 93706 . 1645 "E" Street. Suite 105 . Telephone 12091 485-3200, Fax t209) 485-7427 = Fresno.

Griffith Company Facility Bakersfield, California Job B91090 May 15, 1991 Page 2 Four soil samples were collected from beneath each 8,000 gallon tank, at depths of 2 and 6 feet, from locations at each end of the tanks (See Figure 2, Site Plan). Two samples were collected from depths of 2 and 6 feet below each dispenser, the 500 gallon tank, and beneath each fuel line at a location approximately midway between it's respective tank and fuel dispenser. Soil samples obtained beneath the gasoline tanks, gasoline dispenser, and both fuel lines were tested for Total Petroleum Hydrocarbons - Gasoline (TPH-G), and Volatile Hydrocarbons including Benzene, Toluene, Xylenes, Ethylbenzene (BTXE), and Isopropylbenzene. Samples collected beneath the diesel tank and it's dispenser were analyzed for Total Petroleum Hydrocarbons - Diesel (TPH-D), and Volatile Hydrocarbons. Test results (See Figure 3, Preliminary Test Results) indicate relatively high concentrations of gasoline in samples obtained from beneath the east end of the 8,000 gallon gasoline tank, and lower concentrations in samples collected from beneath the gasoline fuel line. Relatively high concentrations of diesel fuel were indicated in tests performed on samples obtained beneath the diesel tank. Some hydrocarbons were analyzed in samples collected beneath the diesel fuel line, however, those samples were inappropriately tested by SMC Laboratory for TPH-G rather than TPH-D which could alter test results if contamination present beneath that fuel line is diesel. Based on preliminary test results, the Kern County Environmental Health Services Department (KCEHSD) directed Griffith Company to perform a Characterization of Soil Contamination to assess the extent of contamination and to provide suitable remediation alternatives (including "no action"). SOIL CONDIDONS Soils in the vicinity of this site consist of interbedded lenses grading from sand to clay. Generally, the soil lenses are non-uniform and discontinuous. Permeabilities of the subsurface soils may be expected to be moderate to high. BSI( & Associates Characterization of Soil Contamination _., Gnmth Company Facility ~ Bakersfield, California Job B91090 May 15, 1991 Page 3 GROUNDWATER CONDffiONS The site is situated within the SW 1/4, SW 1/4 of the NW 1/4 of Section 8, T3OS1R28E, MDB&M Based on information contained within the Kern County Water Agency May 1989 Water Supply Report, published in May 1990, depth to groundwater beneath the site is reported to be about 165 feet. Shallower "perched" groundwater has not been known to be present beneath the site. SCOPE OF WORK The works cope of this Characterization of Soil Contamination is concerned with assessing the vertical and lateral extent of contamination resulting from leakage of the two 8,000 gallon underground fuel tanks and associated fuel lines, and providing recommendations regarding suitable remedial alternatives. The Characterization would comply with guidelines contained in the KCEHSD's Handbook #UT-35. Our proposed scope of work would include the following: 1. Drill a maximum of 6 test borings at the site to assess the extent of gasoline and diesel fuel contamination. Three test borings would be drilled in the vicinity of each 8,000 gallon tank. Borings would be positioned in a manner as to incorporate contamination resulting from the fuel lines, if that contamination is significantly extensive. The first test boring (B-1) would be drilled over the eastern end of the 8,000 gallon gasoline tank to determine the vertical extent of gasoline contamination. The second boring (B-2) would be drilled about 20 feet northeast from Boring B-1 and the third boring (B-3) would be drilled about 30 feet northward from Boring B-1 to assess the lateral extent of contamination. If field conditions encountered during drilling of B-2 indicate that contamination had not spread that far laterally, then Boring B-3 would be located 10 feet from Boring B-1. Test borings drilled around the diesel tank would be situated in a similar manner as those drilled around the gasoline tank. Boring B-4 would be located over the eastern edge of the diesel tank. Lateral Boring B-5 would be located 20 feet southeast of B-4. Boring B-6 would be situated either 10 or 30 feet southward of B-4 depending on observed field conditions. BSI( & Associates Characterization of Soil Contamination ~, GÍiffith Company Facility Bakersfield, California Job B91090 May 15, 1991 Page 4 " Test borings would be drilled to a maximum depth of 100 feet, or until the vertical extent of soil contamination has been preliminarily evaluated by field observations and instrumentation (photoionization detector), whichever is the lesser depth. Subsurface soils would be logged based on the Unified Soil Ç1assification System. Test drilling would be performed with a BSK truck-mounted continuous flight auger drill rig using 8" hollow stem augers. Augers and sampling equipment would be steam-cleaned prior to entering the site and between borings to prevent cross-contamination. Soil cuttings would be stockpiled on-site and covered with plastic sheeting for eventual disposal by the property owner. The drill crew would consist of a driller and a helper. The field investigation would be supervised by an engineer or a geologist who would be responsible for the field boring logs, recording of field conditions, soil sample handling and preservation, Chain-of-Custody documentation, and cleaning of field equipment. Prior to drilling, we would notify Underground Service Alert of our intention to drill so that underground improvements and utilities may be identified Boring locations would be approved by Griffith Company based on their knowledge of on-site underground improvements. BSK will not be responsible for damage to underground improvements at approved drill locations. 3. Obtain soil samples from the test borings 5 feet below the former tank bottom elevation and at 10 foot intervals thereafter, beginning at an approximate depth of 20 feet. Samples would be obtained by lowering a 2-inch inside diameter sampler containing stainless steel liners inside the hollow stem auger and driving it into undisturbed soils. The sampler would be cleaned with liquinox, a surgical grade biodegradable detergent, and rinsed with potable water between sampling activities. The retrieved sample liners would be capped with aluminum foil, then with pressure fitted plastic caps, and sealed with adhesive tape. Each sample would be affixed with an adhesive-backed label including boring designation, depth of sample, and initials of the individual preparing the sample. The samples would be stored in insulated chests with "Blue Ice" and delivered within 24 hours of sampling to BSK's California-certified Analytical Laboratory for testing.

Selected samples obtained near the diesel tank would be tested for TPH-D and BTXE. 4. Backfill borings to the surface with a sand/cement slurry. The slurry would consist of 7 sacks of Portland Cement per cubic yard of volume. 5. Prepare a Characterization of Soil Contamination Report for Kern County Environmental Health Services Department's review. The report would comply with guidelines contained in KCEHSD Handbook #UT-35. Included in the report would be a description of our field investigation, analytical test results, conclusions, and recommendations concerning remediation alternatives (including "no action"). The report would be prepared under the supervision of a California-registered Engineer or Geologist.

Attention: Mr. Michael Driggs SUBJECT: Characterization of Soil Contamination Workplan Griffith Company Facility (Permit #250003) Bakersfield, California Gentlemen: BSK & Associates has been retained by Griffith Company to perform a Characterization of Soil Contamination concerning leakage from underground fuel storage tanks at their facility. We are providing this Workplan and an accompanying Health & Safety Plan for County approval prior to commencing the field investigation. PROJECT INFORMATION The Griffith Company facility is located at 1898 South Union Avenue, situated near the northeast comer of South Union Avenue and Watts Drive in Bakersfield, California (See Figure 1, Vicinity Map). Three underground fuel storage tanks, associated fuel lines and dispensers were removed from the Griffith Company facility in mid-January of 1991. The storage containers consisted of one 8,000 gallon diesel fuel tank, and one 8,000 gallon tank and one 500 gallon tank used for gasoline. Two fuel dispensers, and two fuel lines were also removed. Tank removal and disposal were provided by MP Vacuum Service Company. Soil sampling beneath the tanks was performed by Mr. George Sweet, Environmental Contractor. Analytical testing of soil samples was conducted by SMC Laboratory.

Two samples were collected from depths of 2 and 6 feet below each dispenser, the 500 gallon tank, and beneath each fuel line at a location approximately midway between it's respective tank and fuel dispenser. Soil samples obtained beneath the gasoline tanks, gasoline dispenser, and both fuel lines were tested for Total Petroleum Hydrocarbons - Gasoline (TPH-G), and Volatile Hydrocarbons including Benzene, Toluene, Xylenes, Ethylbenzene (BTXE), and Isopropylbenzene. Samples collected beneath the diesel tank and it's dispenser were analyzed for Total Petroleum Hydrocarbons - Diesel (TPH-D), and Volatile Hydrocarbons. Test results (See Figure 3, Preliminary Test Results) indicate relatively high concentrations of gasoline in samples obtained from beneath the east end of the 8,000 gallon gasoline tank, and lower concentrations in samples collected from beneath the gasoline fuel line. Relatively high concentrations of diesel fuel were indicated in tests performed on samples obtained beneath the diesel tank. Some hydrocarbons were analyzed in samples collected beneath the diesel fuel line, however, those samples were inappropriately tested by SMC Laboratory for TPH-G rather than TPH-D which could alter test results if contamination present beneath that fuel line is diesel. Based on preliminary test results, the Kern County Environmental Health Services Department (KCEHSD) directed Griffith Company to perform a Characterization of Soil Contamination to assess the extent of contamination and to provide suitable remediation alternatives (including IIno actionll). SOIL CONDffiONS Soils in the vicinity of this site consist of interbedded lenses grading from sand to clay. Generally, the soil lenses are non-uniform and discontinuous. Permeabilities of the subsurface soils may be expected to be moderate to high. BSI( & Associates Characterization of Soil __tamination Griffith Company Facility Bakersfield, California e Job B91090 March 29, 1991 Page 3 GROUNDWATER CONDIDONS The site is situated within the SW 1/4, SW 1/4 of the NW 1/4 of Section 8, T30S/R28E, MDB&M Based on information contained within the Kern County Water Agency May 1989 Water Supply Report, published in May 1990, depth to groundwater beneath the site is reported to be about 165 feet. Shallower "perched" groundwater has not been known to be present beneath the site. SCOPE OF WORK The workscope of this Characterization of Soil Contamination is concerned with assessing the vertical and lateral extent of contamination resulting from leakage of the two 8,000 gallon underground fuel tanks and associated fuel lines, and providing recommendations regarding suitable remedial alternatives. The Characterization would comply with guidelines contained in the KCEHSD's Handbook #UT -35. Our proposed scope of work would include the following: 1. Drill a maximum of 6 test borings at the site to assess the extent of gasoline and diesel fuel contamination. Three test borings would be drilled in the vicinity of each 8,000 gallon tank. Borings would be positioned in a manner as to incorporate contamination resulting from the fuel lines, if that contamination is significantly extensive. The first test boring (B-1) would be drilled over the eastern end of the 8,000 gallon gasoline tank to determine the vertical extent of gasoline contamination. The second boring (B-2) would be drilled about 20 feet northeast from Boring B-1 and the third boring (B-3) would be drilled about 30 feet northward from Boring B-1 to assess the lateral extent of contamination. If field conditions encountered during drilling of B-2 indicate that contamination had not spread that far laterally, then Boring B-3 would be located 10 feet from Boring B-1. Test borings drilled around the diesel tank would be situated in a similar manner as those drilled around the gasoline tank. Boring B-4 would be located over the eastern edge of the diesel tank. Lateral Boring B-5 would be located 20 feet southeast of B-4. Boring B-6 would be situated either 10 or 30 feet southward of B-4 depending on observed field conditions. BSI( & Associates Characterization of Soil "tamination Griffith Company Facility Bakersfield, California . Job B91090 March 29, 1991 Page 4 Test borings would be drilled to a maximum depth of 100 feet, or until the vertical extent of soil contamination has been preliminarily evaluated by field observations and instrumentation (photoionization detector), whichever is the lesser depth. Subsurface soils would be logged based on the Unified Soil Qassification System. Test drilling would be performed with a BSK truck-mounted continuous flight auger drill rig using 8" hollow stem augers. Augers and sampling equipment would be steam-cleaned prior to entering the site and between borings to prevent cross-contamination. Soil cuttings would be stockpiled on-site and covered with plastic sheeting for eventual disposal by the property owner. The drill crew would consist of a driller and a helper. The field investigation would be supervised by an engineer or a geologist who would be responsible for the field boring logs, recording of field conditions, soil sample handling and preservation, Chain-of-Custody documentation, and cleaning of field equipment. Prior to drilling, we would notify Underground Service Alert of our intention to drill so that underground improvements and utilities may be identified Boring locations would be approved by Griffith Company based on their knowledge of on-site underground improvements.

The purpose of this plan is to assign responsibilities, establish personal protection standards and safety procedures, and provide for contingencies that may arise during project operations at the site. This plan complies with, but does not replace, Federal Health and Safety regulations contained in 29 CFR 1910 and 1926, and California Health and Safety Regulations as set forth in Title 8, California Code of Regulations. The provisions of this plan are mandatory for onsite BSK & Associates employees engaged in hazardous material management activities. Changing or unanticipated site conditions may require modification of this site safety plan to maintain a safe work environment. The proposed Scope of Work for this project includes drilling and obtaining subsurface soil samples in the vicinity of a leaking underground fuel storage tank. Drilling would be performed with a truck-mounted hollow stem auger drill rig. Field personnel would include a driller, a driller's assistant, and a geologist or engineer. Prior to drilling, available site plans would be reviewed and Underground Service Alert would be contacted to identify underground improvements and utilities beneath the site. Based on reported results of the Preliminary Soil Contamination Assessment, substances that may be encountered during the field investigation include various hydrocarbon compounds. Concentrations of Total Petroleum Hydrocarbons and associated constituents, including Benzene, Toluene, Ethylbenzene and Xylene isomers, may be present. These hazardous petroleum compounds require that protective measures be taken by the field personnel to limit exposure. MEDICAL SCREENING BSK & Associates personnel working on this project must maintain the BSK medical screening program and undergo a medical evaluation on a six-month interval. The purpose of the medical examination is to monitor personnel health status for evidence of BSI( & Associates Health and Safety Plan Griffith Company Bakersfield, California e e JOB B91090 March 29, 1991 Page 2 adverse health effects from hazardous site work and for personnel suitability for future work assignments of similar activity. EMERGENCY REsPONSE PLAN In the event of an accident or emergency, the following numbers can be called for assistance: County Health Department Police, Fire, Ambulance (805) 861-3636 911 Field crews should be aware of the location and telephone number of the hospital closest to the site. Hospitals in Bakersfield are: Bakersfield Memorial Kern Medical Center Mercy Hospital 420 34th St. 1830 Flower 2215 Truxtun 327-1792 326-2000 327-3371 HEALTH AND SAFE1Y OFFICER (HSO) The HSO for this project shall be the onsite Project Geologist or Engineer directing the field investigation and operational efforts. The HSO for this project shall be Mark Milward. The HSO has primary responsibility for: 1. Maintaining that appropriate personal protective equipment is available and properly utilized by onsite personnel. 2. Advising personnel of these plan provisions, instructing them in the work practices necessary for safety, and familiarizing them with planned procedures for dealing with emergencies. 3. Advising personnel of the potential hazards associated with the operations. 4. Correcting work practices or conditions that may result in injury or exposure to hazardous substances. 5. Preparing accident/incident reports. 6. Halting site operations, if necessary, to correct unsafe work conditions. BSI( & Associates Health and Safety Plan Griffith Company Bakersfield, California e e JOB B91090 March 29, 1991 Page 3 GENERAL HEALTH AND SAFE'IY PRoCEDURES BSK & Associates employees working on this project must comply with the procedures set forth in this Health and Safety Plan and with procedures discussed by the HSO prior to start of work. It is virtually impossible to anticipate all conditions on the site and potential health hazards beforehand Field crews must accordingly exercise common sense and good judgement in their performance on the job and in the approach used in a given situation. This plan contains rules, guidelines and working procedures appropriate to the tasks at hand Field crews shall follow the Health and Safety procedures in this plan. If there are questions, then direction and advice should be sought from the HSO. Chemical hazards onsite include those associated with petroleum compounds. Physical hazards include those from drill rig operation, heat stress, and utilities (underground and overhead), if present. DRILL RIG IlAzARDs Safe work practices for drill rig operation include, but are not limited to: When moving a rig off-road, pay particular attention to obstacles in the route of travel. Have an assistant guide the driver when in close proximity to hazards or if clearance is at a minimum. Set the brakes and/or block the wheels when the derrick (mast) is set up. The derrick must be lowered when traveling off-road. Be certain concerning utility locations and status (energized, charged, etc.) in the area of the rig. Call Underground Service Alert at least 48 hours in advance of performing field work and review available plans in locating utilities. Do not operate a rig within 15 feet of overhead lines. Clear the site of obstructions, debris, etc., prior to setting up the rig. Maintain proper "housekeeping" around and on the rig at all times. Tools should be stored in a manner that permits convenient access yet also provides for personal safety. BSI( & Associates Health and Safety Plan Griffith Company Bakersfield, California e e JOB B91090 March 29, 1991 Page 4 Store flammable fuels only in approved containers. Unattended boreholes must be adequately covered Avoid drilling during an electrical storm. HEAT STRESS AND CONTROL Heat stress is caused by a number of interacting factors, including environmental conditions, clothing, work load, and the individual characteristics of the worker. Because heat stress is one of the most common (and potentially serious) illnesses at work sites, regular monitoring and other preventive precautions are vital. CHEMICAL IlAzARDs It is anticipated that the potential chemical exposure to site personnel should be for short periods of time (intermittent for several days) and the expected levels of gasoline and constituents are not considered a major concern. However, the site is not fully characterized and the potential for exposure to elevated levels of these contaminants may exist. Hydrocarbon compounds are eye and throat irritants at levels around 300 parts per million, and may cause narcotic effects (with symptoms including headache, nausea and fatigue) at higher levels. Long term exposure can affect liver and kidney functions. The following potential exposures may exist at the site: 1. Skin contact with contaminated soil or water. Skin contact will be minimized by wearing appropriate clothing. 2. Inhalation of vapors. Inhalation of vapors will be minimized by air monitoring, and the use of respiratory protection if action levels are exceeded. 3. Ingestion of contaminated soil dusts. Ingestion of soil materials will be minimized by good personal hygiene (washing face and hands with soap and water). An organic vapor analyzer or photoionization detector will be used to monitor for gasoline vapors. The analyzer will be used on a regular basis to monitor ambient air BS( & Associates Health and Safety Plan Griffith Company Bakersfield, California e e JOB B91090 March 29, 1991 Page 5 quality in the vicinity of the borehole. If excessive hazardous levels are encountered, personnel will don protective clothing and exit the area if required PERsONAL PROTECTIVE EQUIPMENT Minimum Protective Equipment for Site Personnel: - Hardhat - Steel-toed boots - Eye protection (face shield or safety glasses) - Ear protection in the vicinity of the drilling - Work gloves - Coveralls, or long-sleeved shirt and long pants The following equipment would be donned at the discretion of the HSO: - Tyvek coveralls - Chemical resistant steel-toed boots - Nitrile, latex or vinyl gloves, as appropriate - Respirator with organic vapor cartridges DECONTAMINATION PROCEDURES A high-pressure steam cleaner will be used for decontamination. Tools, sampling and drilling equipment can be decontaminated by brushing them under a water rinse and/or steam cleaning. Personal protective equipment will be cleaned with brush, soap and water, and discarded if necessary. OPERATION SHUTDOWN Under certain extreme hazardous situations the onsite geologist, engineer or HSO may request that drilling or sampling procedures be temporarily suspended while the hazard is corrected or controlled The HSO will have ultimate authority for operations shutdown and restart.

These costs are recovered by Kern County Environmental Health Services Department in one of the two methods described below. It is your responsibility to select the method of oversight cost recovery under the terms of (A) State contract or (B) County of Kern Local Agreement Option. These options pertain only to costs associated with oversight. (A) STATE CONTRACT The State Leaking Underground Storage Tank Pilot Program provides a mechanism for the State to reimburse the County for County oversight. The County will conduct the necessary oversight and bill the State Water Resources Control Board under this State contract. The State will then charge you, a responsible party, for the costs incurred by both the County and the State, pertaining to your site, under the State terms explained below: Whereas the federal Petroleum Leaking Underground Storage Tank Trust Fund provides funding to pay the local and state agency administrative and oversight costs associated with the cleanup of releases from underground storage tanks; and Whereas the Legislature has authorized funds to pay the local and state agency administrative and oversight costs associated with the cleanup of releases from underground storage tanks; and Whereas the direct and indirect costs of overseeing removal or remedial action at the above site are funded, in whole or in part, from the federal Trust Fund; and Whereas the above individual(s) or entity(ies) have been identified as the party or parties responsible for investigation and cleanup of the above site; YOU ARE HEREBY NOTIFIED that pursuant to Title 42 of the United States Code, Section 6991b(h)(6) and Section 25360 of the Health and Safety Code, the above Responsible Party or Parties shall reimburse the State Water Resources Control Board not more than 150 percent of the total amount of site-specific oversight costs actually incurred while overseeing the cleanup of the above underground storage tank site, and the above Responsible Party or Parties shall make full payment of such costs within 30 days of receipt of a detailed invoice from the State Water Resources Control Board. (B) COUNTY OF KERN LOCAL AGREEMENT OPTION Kern County Environmental Health Services Department is providing this option for those who prefer to pay the County directly and avoid the addition of State costs. Prior to the County's performance of services, this option requires your deposit of $1,000.00 (one thousand dollars) with the County to be held in the Local Option Trust Account. Charges for County oversight are made against this account. In this option, a responsible party must enter into a County agreement, Attachment "B". The environmental sensitivity (Attachment "C") of this site has been reviewed by Environmental Health Services Department to determine the potential threat for groundwater contamination. Only sites determined to be non-environmentally sensitive may e e Bill Cotton March 8, 1991 Page 3 enroll in the Local Option Agreement. The site described above is not in an environmentally sensitive area and may be enrolled in the Local Agreement Option; however, the County of Kern reseIVes the right to cancel any Local Agreement Option should it be discovered that groundwater contamination or a unique, complex hydrogeological condition exists. In such cases, Environmental Health will utilizë the State contract to pay for County oversight activities. The County of Kern reserves this right for any site even when the site is located in a non-environmentally sensitive area. It is necessary for you to respond, in writing, within ten (10) calendar days of receipt of this letter to advise Kern County Environmental Health Services Department of your choice: either the State contract or the County's Local Agreement Option. If you select the County's Local Agreement, please complete and sign the Local Agreement (Attachment B), and return it with your check for $1,000,00 (one thousand dollars) made payable to the County of Kern, addressed to Kern County Environmental Health Services Department, 2700 M Street, Suite 300, Bakersfield, CA 93301, Attention: Accounting - Local Agreement Option. If you select the State contract, please indicate, in writing, that you have made this selection and that you have read the above official notification. Failure to respond within ten (10) calendar days to this notice will automatically result in oversight cost recovery for your site(s) to be placed under the terms of the State contract for Leaking Underground Storage Tanks. If you should have any questions regarding this matter, please contact Susan Gonzales at (805) 861-3636, Extension 510.

Representatives from this department respond to job sites during tank removals to ensure tbat the tanks are safe to remove/close and that the ova-aJ1 job performance is consistent witb permit requirements, applicable laws and safety standards. The following guidelines are offered to clarify tbe inten:sts and cspedations for this department ... 1. Job site safety is one of our primaly concerns. Excavations are inherently dangerous. It is the contractor's respoDSibility to know and abide by CA[..()SHA regulations. The job foreman is responsible for tbe crew and any subcontractors on the job. As a general rule, workers are Dot permitted in improperly sloped excavations or when unsafe conditions exist in the hole. Tools and equipment are to be used only for tbeir designed function. For example, backhoe buckets are never substituted for ladders. 2. 'Properly licensed contractors are assumed to understand the requirements of the permit issued. The job foreman is responsible for knowing and abiding by the conditions of the permit Deviation from tbe permit conditions may result in a stop-work order. 3. Individual contractors will be beld responsible for tbeir post-removal paperwork. Tracking forms,. hazardous waste manifests and analyses documentation are necessary for each site in order to close a case file or move it into mitigation. When contractors do not fonow through on necessaty paperwork, an unmanageabl cldo of incomplete ults. If this continues, processing time for completing new closures will increase.
