A. Yield Investigation (APPENDIX A) /1. The site lithology is comprised primarily of moist sands, silty sands and silts from ground surface to a depth of approximately 82 feet. Soils from a depth of approximately 82 feet to 120 feet, the maximum depth explored, are comprised primarily of sandy silts, sandy clays and clayey sands interbedded with sands of fine to very coarse grains. 2. Petroleum constituents were detected in testholes B2 and B3 by field screening methods. Odors were detected in testhole B2 starting at a depth of 30.5 feet. 3. Soil discoloration associated with petroleum odor was noted at testhole B3 at 4 feet, and B2 between 26 and 30.5 feet just prior to odors being detected. Odors continued in testholes B2 and B3 to the maximum depths explored. 4. HNU 101 Photoionization (PI) meter readings were highest (approximately 200-320 ppm.) in boring B3 from 10 feet to 81.5 feet, the maximum depth explored. Boring B2, B3A and B4 measured 0 to 230 ppm at varying depths. B. Laboratory Analyses of Selected Samples (APPENDIX B) 1. Chemical analyses of soil samples collected during the November 1 to 9, 1989 tank removal project resulted in high levels of total petroleum hydrocarbons (TPH) ranging from 1719.31 ppm in soil sample P9 to 8843.63 ppm in soil sample P6. Benzene levels ranged from 2.4 ppm in soil sample P9 to 58.81 in soil sample P6. 1 e e 111-90 A.S.A 2. Chemical analyses of soil samples collected during the field investigation of July 9 and 10, 1990 verified the presence of petroleum constituents. TPH values of 4200 ppm (B3 at 31.5 feet), 2400 ppm (B3 at 51.5 feet), 4,700 ppm (B3 at 81.5 feet), and 5.2 ppm (B2 at 51.5 feet) were detected. 3. Test results from the west lateral boring B4 resulted in three non detectable levels of petroleum constituents from 110 to 120 feet. 4. Organic lead and Ethylene dibromide (EDB) were not detectable in the two samples tested for these chemicals. / l/3. CONCLUSIONS 1. Petroleum constituents of Benzene, Toluene, Xylene, Ethybenzenze (BTX&E) and Total Petroleum Hydrocarbons (TPH) have impacted the soil at the subject site. 2 . A plume of petroleum constituents in soil has been partiall y defined. Non detectabl e laboratory resul ts indicated that the plume does not extend west of B4 beyond a vertical depth of 110 feet, with minor detectable levels above 110 feet. Laboratory results of the northwest boring B3A indicated that minor detectable levels exist to 120 feet, the maximum depth explored. Boring B2 located south of B3A did not detect 1 eve 1 s above 26 feet, but minor levels were detected from 36.5 feet to 51.5 feet. Laboratory results and field findings do not precisely define the plume extent to the north, south or east. The vertical extent of the plume is not defined. However vertical variations in petroleum constituent have been identified. Laboratory results indicated high constituent levels at boring B3 from 11.5 to 81.5 feet. Soils encountered were predominately fine to coarse grained sands. Laboratory results of the boring B3A soil samples, from a depth of 90 to 120 feet, indicated minor detectable levels. Soils encountered were comprised of sandy s i 1 ts , sandy clays and clayey sands wi th interbedded coarse grained sands. These results seem to indicate that petroleum constituent were concentrated above 90 feet with light levels migrating to deeper depths. 4. Ground water was not encountered in the borings. 2 e e 111-90 A.S.A SCOPE OF WORK The scope of work for the investigation included the following tasks: 1. Researching geological soils maps, seismic maps, water supply maps and reports (APPENDIX C). 2. Drilling 4 exploratory borings in the vicinity of the removed gasoline tanks and fuel island (See FIGURE 3 ). 3. Visually classifying and continuously logging substrata encountered at each testhole boring location (APPENDIX A) . 4. Collecting soil samples at 5 foot intervals and preparing them for laboratory testing. 5. Field screening soil samples with HNU PI 101 meter (APPENDIX A). 6. Conducting laboratory tests on selected soil samples collected from testhole borings (APPENDIX B). 7. Analyzing and interpreting field and laboratory test results. SITE DESCRIPTION: The subject property formerly operated as Pence Automated Fuels is located at 901 E. 19th street also known as 901 E. Truxtun Ave, Bakersfield, California. The site is located east of Beale Avenue, between East Truxtun Avenue and East 18th Street. The Assessor's Parcel Number is 017-160-07, situated in Section 29, Township 29 South, Range 28 East, Mount Diablo Baseline and Meridian. The owner is Pence Petroleum Company. (FIGURE 2) 3 e e 111-90 A.S.A SITE HISTORY: The subject site was purchased by Pence Petroleum Company in 1986. Ownership of tile site prior to 1986 was held b~Davies Oil, -------...-.- --._~~-~ -~ - ~.,._-- Bakersfield, CA. Information regarding specific site history was unavailable. On November 1, 1989 three underground storage tanks (1-6000 gallon regular gasoline, 1-6,000 gallon premium unleaded gasoline, 1- 10,000 gallon unleaded gasoline) and one fuel island were excavated and removed from the subject property. Soil samples were obtained from two and six feet below the bottom of the tanks and fuel islands by MP Vacuum of Bakersfield. (FIGURE 3) The soil samples were analyzed by BC Laboratories Inc. for Benzene, Toluene, Xylene, Ethylbenzene (BTX&E) and Total Petroleum Hydrocarbons (TPH).

Benzene levels ranged from 2.4 ppm in soil sample P9 to 58.81 ppm in soil sample P6. TPH ranged from 1719.31 ppm in soil sample P9 to 8843.63 ppm in soil sample P6. Laboratory analyses of soil samples P1, P2, P3, P4, P8, P11, P12, P13 and P16 detected varying levels of the petroleum constituents, while P7, P14 and P15 levels were non detectable (APPENDIX B). As a result of the detection of petroleum constituents in the soil samples, Pence Petroleum Company was required to provide a site characterization work plan proposal pursuant to a March 2, 1990 request from the Resources Management Agency, Department of Environmental Services, County of Kern. Pursuant to the request, Pence Petroleum Company contracted Associated Soils Analysis for the site characterization activities. On April 30, 1990 a workplan proposal was submitted to County of Kern, Department of Environmental Health Services for review. On May 7, 1990 Flora Darling, Hazardous Materials Specialist, County of Kern, requested an addendum to the workplan inclusive of changing the proposed borehole location and decreasing the amount of boreholes from four to three (APPENDIX C). 6 e e 111-90 A.S.A On June 6, 1990 a revised Work Health and Safety Plan was prepared and submitted to the County of Kern for review. The workplan was accepted for the site characterization by the County of Kern on June 15, 1990 (APPENDIX C). Commencement of the site charac- terization began on July 9 and 10, with the drilling of only two boreholes due to conditions encountered during dri 11 ing. Subsequently, two additional boreholes were drilled on November 6 and 7, 1990 to further characterize the site. SITE CONDITIONS 1. The subject property is located east of Beale Avenue, between East Truxtun Avenue and East 18th Street. 2. The subject property is vacant. A drive way and parking area east of the property separates the site from a metal commercial building divided into multi purpose businesses. The businesses were occupied at the time of the field investigation. 3. The subject property is currently unpaved. 4. The site is surrounded on the south, along 18th Street by residences, west along Beale Avenue by grain silos, north along East Truxtun Avenue by a vacant lot, a single family residence and commercial buildings, and east by a commercial building. 5. The site is supplied by commercial utilities, sewer and water lines. 7 e e 111-90 A.S.A SOIL LITHOLOGY The soil types encountered at the site testhole borings consisted primari ly of most sands, si I ty sands and si Its to a depth of approximately 82 feet. An import sand backfill was encountered in the areas of the removed fuel tanks and fuel island. Soils from a depth of approximately 82 to 120 feet, the maximum depth explored, are comprised primarily of sandy silts, sandy clays and clayey sands with interbedded sands. Cementation of soils was observed from approximately 65 feet to 105 feet and again from 116 feet to 120 feet. Cemented sand pods were encountered in boring B4 at 84 feet to 88 feet and at 116 feet to 120 feet. Figure 4 details the location of the borings. A total of four soil boring were drilled. Boring B3 and B2 were drilled July 9 and 10, 1990 respectively. Boring B4 and B3A were drilled November 6 and 7, 1990 respectively. Soils encountered in testhole boring B2 consisted primarily of moist sands with alternating stratas of sandy silts and silts. Soil grains varied from very fine to very coarse. Soil discoloration was observed at 26 to 30.5 feet with odors detectable from approximately 30 to 51.5. Borehole B2 was terminated at 51.5 feet due to difficulties encountered during drilling. 8 e e 111-90 A.S.A Soils encountered in testhole boring B3 were similar in composition to B2. Soil discoloration was observed at four feet and odors were detectable throughout the entire depth of the boring. Light soil cementation was detected at 70 to 76 feet. Boring B3 was terminated at 81.5 feet due to auger refusal. Soils encountered in testhole boring B3A between the depths of 81.5 to 120 feet consisted of alternating strata of sandy clays, clayey sands, sandy s i 1 ts, s i 1 ty sands interbedded with fine to very coarse sand grains. Slight soil cementation was observed between 94 to 95 feet, and well indurated clays and partially cemented sands were observed between 116 to 120 feet. The soil boring was terminated at 120 feet and ground water was not encountered. Soils above 81.5 feet were not classified due to sluffing of soils within the borehole. Soils from boring B4 were classified between the depths of 61.5 to 120 feet. Soils encountered consisted of alternating stratas of s i 1 ty sands, clayey sands sandy s i 1 ts sandy clays and sands. Soil grains varied from very fine to very coarse. Soil cementation was observed the entire depth on the boring. Cemented sand pods were observed between the depths of 84 to 88 feet. In general soi 1 s consisted of sands ranging from coarse grains to a depth of approximately 75 feet. fine to very Soils below 9 e e 111-90 A.S.A this depth were comprised of alternating sandy clays to clayey sands, partially to well cemented and ranging from fine to very coarse sand grains. The following general description and Unified Classification System symbols were used throughout the boring logs. SW Sand: Varying shades of yellowish brown, moist, fine to very coarse, angular to subangular grains, well graded, medium to very dense SP Sand: Varying shades of yellowish brown to light olive grey, moist, fine to very coarse, angular to subangular grains, poorly graded, dense, light cementation SM Silty sand: reddish brown, moist, medium to coarse subangular sand grains, slightly cemented SM\ML . Sandy silt: Varying shades of yellowish brown, moist to very moist, very fine to coarse, subrounded to subangular grains, loose to medium ML Silt: Yellowish brown to reddish brown, moist, very fine grain, low to medium plasticity, cementation SC Clayey moist, sand: Yellowish brown to reddish fine to very cohesive, cementation brown, CL Sandy clay: brownish yellow to reddish brown, moist, medium to very coarse angular to subangular sand grains, low to medium cohesion, cemented CL Clay: reddish brown, plasticity moist, low to medium See the attached Testhole Boring Logs for detailed descriptions of subsurface soils (APPENDIX A). Cross section of the soil strata is presented in FIGURE 4. 10 e e 111-90 A.S.A GEOLOGIC CONDITIONS The study area is located in the southeast end of the San Joaquin Valley in a predominately urban area. The San Joaquin Valley is bounded by the Sierra Nevada Mountains on the east, Coastal Range on the west, and the Tehachapi and San Emigdo Mountains on the south. The San Joaquin Valley is joined on the north by the Sacramento Valley which is the northern extension of the Central Valley. Geologically the San Joaquin Valley is a structural trough filled with continental and marine sedimentary deposits. Bakersfield is built on quaternary alluvial plains and fans of the Kern River which overl ie tertiary continental deposits. These sedimentary layers are comprised of interbedded gravel, sand, silt and clay. Crystalline basement rock outcrops approximately 12 miles to the east of Bakersfield. The Kern County Soil Survey classified the site area as Urban Lànd soil which is not described in the soil survey. Soils in this area are similar to Kimberlina fine sandy loam, Cajon loamy sand and Wasco sandy loam. Permeability ranges from moderate to rapid. The topography of the land surface associated with these soils has 0 to 2% slopes. 11 e e 111-90 A.S.A Kern County is classified as Zone IV seismic area of the Uniform Building Code. The nearest active faults are the San Andreas, Owens Valley, and White Wolf Faults at 40 miles, 105 miles and 20 miles, respectively, from Bakersfield. GROUND WATER CONDITIONS Ground Water occurs under both confined and unconfined conditions in the San Joaquin Valley. The degree of confinement varies widely because of the heterogeneity (variabi I i ty) of the continental deposits. The body of fresh ground water in the San Joaquin Valley is contained in principally unconsolidated continental deposits of Pliocene to Holocene Age (0-7 million years old) that extend to depths ranging from less than 100 feet to more than 3,500 feet. Along the eastern boundary of the valley at shallow depths, the base of fresh ground water occurs in more consolidated marine and continental sedimentary rocks of Tertiary Age (2-65 million years old) . The estimated depth to the regional groundwater aquifer in the general vicinity of the site is approximately 185 to 200 feet below ground surface. Groundwater was encountered at approximately 187 feet below ground surface, on February 24, 1989, at 920 East Truxtun Ave., a property located north of the subj ect site. Perched water is known to occur in Bakersfield. However, 12 e e 111-90 A.S.A hydrologist in the Kern County Water Agency are reinterpreting the perched water situation in the Bakersfield area. The aquifer in this area would best be described as semiconfined, according to Water Agency personnel. The nearest water wells in the area are located as follows: WELL LOCATION DEPTH TO WATER Between Baker and Kern street On Beale Avenue, north of California Blvd. Between Tulare street and Kern street 184 feet 186 feet 200 feet This information was provided by California Water Service on April 27, 1989. The regional groundwater is to the southwest, per information furnished by the Kern County Water Agency (Tom Hal s I ebacher) . Groundwater in Kern County is pumped for agriculture, industrial uses (primarily oil field operations), and domestic use. Water quality is fairly high in confined aquifers beneath the Corcoran clay, but is of poor quality in unconfined aquifers above the Corcoran clay. 13 e e 111-90 A.S.A FIELD INVESTIGATION The field investigation consisted of dri 11 ing, logging and sampl ing four (4) exploratory testhole borings in the vicinity of the previously removed underground fuel tanks and fuel island on July 9 & 10, 1990 and November 6 & 7, 1990. Initially, three borings were to be drilled, as requested by the County of Kern, to determine the presence and extent of petroleum constituents associated with the removed fuel tanks, island and associated piping. Observation and detection of odors associated with petroleum constituents were encountered at high levels during the drilling of the first two borings, B2 and B3. Borings B2 and B3 were terminated at 51.5 and 81.5 feet, respectively, due to conditions encountered with dense soils and auger refusal. The third boring, Bl, was not drilled to eliminate the duplication of sampling based on levels encountered in testhole boring B2 and B3 (FIGURE 3). On November 6 & 7, 1990, two additional testhole borings, B3A and B4, were drilled to further define the lateral and vertical extent of petroleum contamination. Due to soil conditions encountered during the previous drilling, a Mobile B 80 mud rotary drilling rig with a Christianson 94 mm wire core was uti 1 ized for the testhole borings. Boring B3A was initiated on November 6, 1990, but was terminated at a depth of approximately 40 feet due to a 14 e e 111-90 A.S.A loss of fluid circulation in the loose sand backfill of the tank excavation. The dri 11 ing rig was re located and boring B4 was drilled to a depth of 120 feet. On November 7, 1990, a 10 inch auger was drilled into the previous B3A boring location to a depth of 40 feet to serve as a conductor casing for the testhole. A 6- 5/8 inch auger was then utilized to complete the boring to a depth of 120 feet (FIGURE 3 ). The soils at each of the exploratory testhole borings were visually classified and continuously logged (APPENDIX A). Representative soil from each soil location depth were field screened using a HNU PI meter to determine the levels of petroleum constituent. Soil samples were collected at 5 foot depth intervals starting at 5 feet below ground level in borings B2 and B3, and terminating at 51.5 and 81.5 feet respectively. Soil samples in boring B3A and B4 were collected at 5 foot intervals, starting at 89.5 and 74.5 feet, respectively, and terminating at 120 feet in depth. PRIMARY SITE INVESTIGATION Underground utilities were located and marked at the site by Underground Services Alert (USA) prior to the drilling operations. Testhole boring location were probed to a depth of four feet to alleviate the possibility of damaging any underground utilities or obstruction. 15 e e 111-90 A.S.A TESTHOLE SOIL BORINGS AND FIELD SAMPLING GUIDELINES DRILLING METHODS A truck-mounted Mobile B-80 drill rig with 4 ~ inch inside diameter hollow stem auger (AASHTO Designation T25177) and 2 inch split spoon sampler was used to drill testhole borings B2 and B3. Due tc soil conditions encountered drilling B2 and B3, a Mobile B 80 muc rotary dri 11 ing rig with a Christianson 94 mm wire core wa~ utilized to drill borehole B3A and B4. Mud used while drilling tc a depth of 81.5 feet was flushed, barreled and replaced prior tc continuing boreholes B3A and B4 to prevent the cross contaminatior of petroleum constituents to soils of deeper depths. The drillinç equipment was pre-cleaned by steam prior to and between eacr borehole drilling. Drilling muds, soils and waste water producec during drilling procedures were contained in 55 gallon 17H stee: drums removed from the subject site by MP Vacuum Truck Service Inc, on December 13, 1990. FIELD SOIL SAMPLING AND LOGGING PROCEDURES Undisturbed soil samples were collected at five (5) foot interval~ from each of the testhole borings. Personnel involved ir collecting the soil samples and classifying the soil were under the 16 e e 111-90 A.S.A direct supervision of the project engineer and fully experienced in the field of environmental and geotechnical drilling. Soil samples from boreholes B2 and B3 were collected using a 2 inch inside diameter by 18 inch long split spoon sampler. Three, 2 inch outside diameter by 6 inch long brass tubes were inserted into the sampler prior to use. After each soil sample was collected, the sample tube from the bottom of the sampler was immediately sealed in the field by placing teflon covers over the open ends of the tube and covering the ends with plastic caps. An adhesive tape was placed around the plastic caps to ensure that the cap was secured and an airtight seal was maintained. The soil from the middle sampler tube or the sampler shoe was placed in foil covered glass container depending on odors encountered and other field conditions. After approximately ~ hour, a field reading was taken by inserting the HNU 101 PI meter probe through the foi 1 cover. The field readings were recorded and used to determine the levels of fuel contamination encountered in the testhole and to assist in selecting the soil samples to be analyzed by the laboratory (APPENDIX A). Soils encountered from the sampler shoe, ends of the bottom sample tube and remaining 2 sample tubes were used to log and classify soils in accordance with the Unified Soil Classification System 17 e e 111-90 A.S.A during dri 11 ing operations (APPENDIX A) . Standard penetration blow counts were recorded during soi 1 sampl ing. The standard penetration tests consisted of using a 140 pound drop hammer fall ing a distance of 30 inches to drive the sampler into the undisturbed soil and recording the number of blow counts required to drive the sampler each 6 inch increments. Soil samples from boreholes B3A and B4 were collected using a Christianson 94 mm wire core sampler obtained in five foot increments. Soil samples were obtained in 2 inch outside diameter by 6 inch long brass tubes from the bottom of the core sampler. After each soil sample was collected, the sample tube was immediately sealed in the field by placing teflon covers over the ends of the tube and covering the ends with plastic caps. An adhesive tape was placed around the plastic caps to ensure that the cap was secured and an airtight seal was maintained. Field reading procedures for odors and field conditions were similar to techniques used for boreholes B2 and B3. Soils encountered from the sampler shoe, ends of the bottom sample tube and remaining soil within the core sampler were used to log and classify soil in accordance with the Unified Soil Classification System during drilling operations (APPENDIX A). Lithologic descriptions that were included in the borehole log were: Soil type, color, moisture description, grain size and 18 e e 111-90 A.S.A shape, compactness or hardness, cohesiveness, grading, extent of weathering or fracturing, and sample odor. Drilling rates, standard penetration tests, HNU PI Meter readings, sample numbers and percent recovery of the samples were also noted in the borehole field log (APPENDIX A). The split spoon sampler, Christianson 94 mm well core sampler and sample tubes were precleaned by steam and Trisodium Phosphate (TSP) detergent wash and distilled water prior to use and between each sample interval. Equipment was stored in clean plastic bags when not in use. All soil samples were labeled appropriately in the field. Labels included: Sample location, depth, date, time, job number, and field identification number. Samples were placed immediately in an insulated storage container cooled by blue ice. The temperature inside the storage container was maintained at 4 degrees Celsiusj39.2 degrees Fahrenheit and monitored with a thermometer to ensure that the temperature remained constant. A chain of custody record (APPENDIX B) accompanied the samples. Chain of custody records include: Sample location, depth, date, time, job number, field identification number, temperature of the soil sample container, analysis required and personnel collecting samples. A field log book was maintained containing essentially 19 e e 111-90 A.S.A the same information as the chain of custody record with the addition of any field observations about the sample. Samples collected on July 9 & 10, 1990 were delivered to B.C Laboratories¡ Inc. within 24 hours of collection. Samples collected November 6 & 7, 1990 were delivered to Beckman Environmental Laboratory, within 48 hours of collection. Both laboratories are State Certified hazardous waste testing laboratories. Temperature of at least 4 degrees Celsius was maintained in the insulated storage container prior to and during transportation of the samples to the laboratory. Once the samples were delivered to the laboratory, the chain of custody was signed by the laboratory indicating that the possession of the samples had changed. The soil samples were analyzed within the required 14 day period following collection. TESTHOLE BORING CONTAINMENT AND ABANDONMENT The soil cuttings, and mud generated from the boreholes were placed in 55 gallon 17 H steel drums. The drums were removed from the subject site by MP Vacuum Truck Services Inc., on December 13, 1990 (APPENDIX C). After drilling was completed, testhole borings B2 and B3 were backfilled with Class B concrete. Borings B3A and B4 were 20 e e 111-90 A.S.A backfilled with 3/8 inch bentonite pellets. The boreholes were backfilled from the bottom of the borehole to the ground surface. FIELD INVESTIGATION RESULTS The field investigation included soil classification and logging, petroleum odor detection, and HNU 101 Photoionization meter measurements. The soil classification results are described in the section Soil Litholoqy and are graphically presented in Figure 4. The HNU PI meter was used to record levels of fuel contamination encountered in the testhole and to assist in selecting the soil samples to be analyzed by the laboratory (APPENDIX A ). The investigation resul ts invo I ving petro I eum constituent detection are described below. Testhole borings B2 and B3 were drilled on July 9 & 10, 1990. Testhole borings B3A and B4 were drilled on November 6 & 7, 1990. The testholes with the highest HNU readings were B2 and B3 which coincide with the laboratory analytical results. Testhole boring B2 was located at the north central half of the excavated 6000 gallon regular leaded fuel tank. Petroleum odors in B2 were detectable beginning at approximately 30 feet and continued through the depth of the boring. HNU readings, taken every 5 feet, ranged from 18 ppm at 30 feet and increased to 260 ppm at 51.5 21 e e 111-90 A.S.A feet. Petroleum odors were also detected from 30 to 51.5 feet. Soil discoloration was noted at approximately 30 feet below ground level. Testhole boring B3 was located 5 feet east of the excavated 10,000 gallon unleaded fuel tank and approximately 5 feet north of the prior fuel island. Petroleum odors were encountered throughout the entire depth of boring B3. HNU readings, taken every 5 feet, ranged from 70 ppm at approximately 5 feet and increased to 320 ppm at 81.5 feet. HNU reading decreased slightly between 55 to 75 feet where sandy soils were encountered. Soils described as silt were encountered above 55 feet and below 75 feet. Soil discoloration was noted at approximately 4 feet below ground level. HNU readings of testhole boring B3A began at 89 feet with detection of 50 ppm and decreased to 0 ppm at 120 feet, odors were not detected. Boring B3A was located 5 feet west of B3 and within the backfill of the 10,000 gallon underground tank excavation. Testhole boring B4 was located at the south west corner of the subject site. HNU readings of the testhole began at 62 feet with detection of 150 ppm and decreased to 7 ppm at 120 feet, odors were not detected. 22 e e 111-90 A.S.A LABORATORY ANALYTICAL RESULTS Soil samples collected from testholes B2 and B3 on July 9 & 10, 1990 were transported to B.C. Laboratories, Inc. of Bakersfield, CA. Soils samples collected from testholes B3A and B4 on November 6 & 7, 1990 were transported to Beckman Environmental Laboratory, Portervi11e, CA. Both laboratories are State Certified hazardous waste testing facilities. Selected samples collected from the borings were analyzed for the following constituents: BTX&E TPH (gasoline and diesel) EDB & DBCP Organic Lead EPA Method 8020/5030 D.O.H.S. L.U.F.T. Method Modified Method AB 1803 State Draft Analytical Laboratory results are summarized in Appendix B. Details of the results are described on the laboratory reporting forms (APPENDIX B). LABORATORY RESULTS November 1, 1989 Tank and Fuel Island Removal Samples Soil samples collected during the tank removal project were analyzed at BC Laboratories, Inc., of Bakersfield, CA. The results of the laboratory analysis indicated the presence of petroleum constituents concentrated at P5, P6, P9 and P10. Benzene levels ranged from 2.4 ppm in soil sample P9, to 58.81 ppm in soil sample 23 e e 111-90 A.S.A P6. TPH ranged from 1719.31 ppm in soil sample P9 to 8843.63 ppm in soil sample P6. Laboratory analyses of soil samples P1, P2, P3, P4, P8, P1!, P12, P13 and P16 detected varying levels of the petroleum constituents, while P7, P14 and P15 soil sample results were nondetectable. July 9 & 10, 1990 and November 6 & 7, 1990 Field Investigation Samples Laboratory analytical results of the soil samples collected from the site borings resulted in boring B3 having the highest values of BTX & E and TPH from 11 feet to 81.5 feet, the maximum boring depth explored due to soil conditions encountered. TPH (diesel) was detected in B3 at 71.5 feet and in B2 at 51.5 feet. Detection of TPH may result from past diesel fuel storage, dated fue 1 or organic matter. Petroleum constituents in B2 were detected from 36.5 feet to 51.5 feet, the maximum depth explored due to soil conditions, which coincided with detectable odors, HNU readings and soil discoloration noted at the time of the borehole drilling. Organic lead, EDB and DBCP were non-detectable in soil samples obtained from B2 at 16.5 and 26.5 feet. BTX&E and TPH were detected in B3A from 89.5 to 120 feet and in B4 from 74.5 to 104 feet. Soil 24 e e 111-90 A.B.A samples obtained from 109.5 to 120 feet in B4 had no detectable levels of petroleum constituents. No free standing groundwater was encountered at 120 feet, the maximum depth explored at the subject site. 25 e e 111-90 A.S.A ENGINEERS NOTE This report has been prepared for the Pence Petroleum Company, as it pertains to property located at 901 E. 19th street, Bakersfield, California. The findings and conclusions rendered in this report are opinions based on the field investigation and laboratory testing of soil samples collected during this study. This report does not reflect subsurface variations which may exist between sampl ing points. These variations cannot be anticipated, nor could they be entirely accounted for, in spite of exhaustive additional testing. Nor should this report be regarded as a guarantee that no further contamination, beyond that which could have been detected within the scope of this investigation, is present beneath the said property.

Our comments are as f 011 ows : 1. Gradient is not mentioned. Gradient is necessary to determine the most feasible boring locations. A U.S.G.S. map showing contours should be submitted for this location. The map may be 1 imited to the area undergoing site characterization. 2. Boring locations are spaced too far apart and are not located to best define the suspected contaminant plume. Bore holes shall be limited to three; four are excessive. 3. Soil sampling shall begin at grade and proceed at five foot intervals and at any change in lithology. 4. All underground utilites and above ground obstructions (power lines) shall be depicted on the plot plan. 5. Constituents to be analyzed shall include total petroleum hydrocarbons (gasoline) and BXTE. Analyses for the removed 6,000 gallon leaded gasoline tank shall include organic lead and E.O.B. Upon receipt of the above addendum information and a revised plot plan our office will continue the review. A consultation may be scheduled by appointment if necessary.

Truxtun Avenue, Bakersfield, California. 1.1 PURPOSE The soil investigation described in this workplan has the following objectives: * Further assess the vertical and lateral extent of fuel hydrocarbons in the sub-surface soils; * Install one vapor extraction well and possibly one vapor extraction/inlet well. 1.2 SCOPE OF SERVICES The scope of services described in this workplan includes: * Development of a site safety Plan; * Advancing two (2) soil borings after obtaining any necessary permits; * Collecting soil samples at approximately 5-foot intervals and preparing field boring logs; * Field screening soil samples for the presence of hydrocarbon vapor with a Photo-Ionization detector(PID); * Collection and submittal of representative soil samples to B.C. Laboratories, Inc. for fuel analysis of fuel hydrocarbons as gasoline, and the gasoline constituent volatile aromatics using the D.H.S L.U.F.T. Method and EPA Method 8020, respectively; * Installation in one of the borings of one (1) 4-inch diameter vapor extraction well; and possible completion of the second boring as a 4-inch diameter air inlet well; * Preparing a report summarizing methods and results of the soil investigation. 1.3 SCHEDULE AquaGeosciences, Inc. anticipates beginning work described in this workplan within one week pending approval from KCEHSD and authorization to proceed from Pence Petroleum. /sc" /C:WORKPLAN/PENCEINV.WKI' 1 e e In general the soil borings will be completed within one week of mobilization to the site depending upon the availability of a qualified drilling rig, the occurrence of good weather, and other factors including client needs and site-specific conditions. Installation of the vapor extraction/inlet wells in the soil borings will be completed concurrently. Upon completion of the investigation AquaGeosciences, Inc. will issue a Draft Report to our Client. Upon approval, and revision if necessary, AquaGeosciences, Inc. will submit a Report of Findings to KCEHDS that is stamped and certified by a Registered Geologist and/or civil Engineer (R.G. and/or R.C.E.). 2.0 BACKGROUND The site is located at 901 E. Truxtun Avenue, Bakersfield, California as shown on Exhibit 1. The subject property is located east of Beale Avenue, between East Truxtun Avenue and East 18th street. The assessor's Parcel Number is 017-160-07, situated in section 29, Township 29 South, Range 28 East, Mount Diablo Baseline and Meridian. 2.1 FACILITY DESCRIPTION The property is currently unoccupied and was formerly operated as Pence Automated Fuels by the Pence Petroleum Company. 2.2 PROJECT HISTORY On November 1, 1989, two (2) 6,000 gallon underground gasoline storage tanks, one (1) 10,000 gallon underground gasoline storage tank, one dispenser island and associated product lines were removed from Pence Petroleum's Automated Fuels Cardlock at 901 E. Truxtun Avenue, Bakersfield, California. Soil Samples collected at that time indicated that the soil had been impacted with gasoline, and that a site characterization study would be required. Subsequently, Associated Soils Analysis advanced four soil borings to a maximum depth of 120 feet below surface grade. Boring B-3, advanced through the location along the product line where the release is believed to have originated, detected gasoline at 24,000 mg/kg at 50 feet below surface grade. That boring was terminated at 80 feet below surface grade with TPH as gasoline detected at 4,700 mg/kg. Boring B-3A advanced ten feet to the west detected TPH as gasoline at 0.54 mg/kg at 90 feet below surface grade, and had indications of continued low levels of impaction to 120 feet below surface grade. The previous Phase I assessment work has partially delineated the vertical limit of soil impaction beneath the probable product line release, and the lateral limits of the plume to the north, east, and south. Upon review, the County requires that the plume be further assessed with an additional Phase II characterization. lac!: IC:WORKPLAN/PBlfCEIlfV.WKP 2 - - Borings will be advanced to further assess the lateral and vertical ex'tent of the plume, and then be completed as vapor extraction or inlet wells depending on the field results. 3 . 0 WORKPLAN AquaGeosciences, Inc. proposes to install one (1) 4-inch diameter vapor extraction well within the plume with subsequent manifolding to a vapor extraction unit and possibly one (1) 4" diameter air inlet well if the second soil boring is determined to be outside of the contaminated plume. 3.1 SOIL BORING AND VAPOR EXTRACTION WELL DEPTHS AND LOCATIONS Exhibit 2 shows the proposed location of the extraction well, as well as the proposed location of the new extraction/inlet well. The locations, depths and screened intervals have been selected to provide lateral and vertical coverage of the impacted plume as interpreted from prior assessment information. The vapor extraction well located in the center of the plume will most likely be screened from 65 feet to 100 feet in depth. After installation of the aforementioned Soil Borings and Vapor Extraction/Inlet Wells, AquaGeosciences, Inc. will reinterpret the lateral and vertical extent of the contamination plume. AquaGeosciences, Inc. will use existing chemical analytical data in conjunction with newly acquired chemical analytical data to provide a reinterpretation of plume definition. The reevaluation will be presented in report format and will include interpretive cross- sections. 3.2 BORING METHODS The borings will be advanced using a Mobile Drill B-80, or equivalent, equipped with a 8-inch or larger hollow stem continuous flight auger in accordance with ASTM Method D 1452-80 for soil investigations and sampling by auger borings. If the auger rig proves unsuccessful, a Failing 1250 air rotary drilling rig equipped with a wireline and hammer sampling device will be used. The auger and hammer will be steam cleaned prior to drilling each boring. The lithology and other pertinent data will be recorded on a field boring log in .J.ccordance ..vi th ASTM Method D 2488-84 for visual description and identification of soils. Borings will be logged by a California Registered Geologist and/or civil Engineer. Cuttings and other spoil from the borings will be placed on visquene and allowed to aerate or in 55 gallon DOT drums. /scr IC: ~()RKPLAN IPENCEINV. WKP 3 e e 3.3 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 EPA protocols, recorded on a Chain-of-Custody form, placed in a cooler at 4°C 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. 3.4 SOIL ANALYSES The soil samples will be analyzed by B.C. Laboratories, Inc., a California State Certified Laboratory in accordance with state guidelines and EPA protocols. The samples will be analyzed for fuel hydrocarbons, benzene, toluene, xylene, and ethylbenzene (BTXE) using the D.O.H.S. L.U.F.T. Method and EPA Method 8020, respectively. 3.5 FIELD SCREENING Soil samples will be collected using three six-inch brass tubes installed inside a spli tspoon 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 upon collection. 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, and stored for a period of 15 minutes. A standard heads pace reading will be collected at this time and noted on the boring log. 3.6 INSTALLATION OF VAPOR EXTRACTION WELLS AND MANIFOLDING FOR VES OPERATION The vapor extraction well will be completed as shown on Exhibit 3. The well casing will consist of Schedule 40, factory slotted (0.020 inch), four inch diameter (I.D.) hydrolock flush threaded PVC pipe. A flush threaded bottom cap will be provided. The slotted section will extend across the contaminated areas, and the annular filter pack will consist of Number 3 Monterey sand. The filter pack will /scr /C:~~RKPLAN/PENCErNV.WKP 4 e e be placed from total depth to 3 feet above slotted interval. One foot of bentonite pellets will be poured above the sand to form a seal. Cement grout will extend from the bentonite seal to the surface. Well cover boxes ("Christy Boxes") will be set in cement at surface grade. The air inlet well, if installed, will be completed as above and as depicted on Exhibit 4. 4-" 0 FINAL REPORT When the investigation process is deemed complete, a Phase II assessment report will be submitted to the Client. This report will include all field operations, analytical data, final conclusions, and recommendations. The report will also contain recommendations for the type of vapor extraction system best suited for this site. 5.0 OUALITY ASSURANCE PLAN This section describes field and analytical quality-assurance procedures to be followed during the soil investigation. 5.1 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 3.3 and 3.4. 5.2 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. A properly completed Chain of Custody document will be submitted to the analytical laboratory along with the sample. The laboratory's assigned number will be properly entered on the form. A quality control officer at the lab will verify integrity of samples /scr /C:WORKPLAN/PENCErNV.WKP 5 e e submitted, proper sample volume, correctness of containers used and properly executed Chain-of-Custody document. Pertinent information will be entered into a log book kept by the laboratory. 5.3 ANALYTICAL OUALITY ASSURANCE In addition to routine calibration of analytical 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. EPA 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 EPA reference standards; 4.) Verification of results with an alternative method. 6.0 SITE SAFETY PLAN Appendix A contains a Site Safety Plan which complies with the Worker Right to Know Regulations and CAC Title 26.

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 the property previously described for the purpose of further site characterization, installation of one (1) Vapor Extraction Well and possible installation of an air inlet well. Soil samples will be collected at five-foot intervals during exploratory drilling using California modified split-spoon sampler through hollow-stem auger. All possible efforts will be made to collect undisturbed samples. Each sample that is to be chemically analyzed will be collected in a brass sleeve, capped with lined plastic lids, sealed with tape, and placed on ice in a cooler immediately. All Chain-of-custody protocol will be followed. Drilling equipment will be brought to the site and operated by a subcontractor: Melton Drilling Company 1701 Downing Avenue Bakersfield, California 93308 (805)589-0521 C-57 License #508270 The SSP describes the means for protecting all on-site personnel from deleterious contamination or personal injury while conducting on-site activities. As described below AGI will meet all requirements promulgated by the California Department of Health Services. SITE BACKGROUND This property, located at 901 E. Truxtun Avenue, Bakersfield, California, is currently unoccupied, but was formerly operated as Pence Petroleum Automated Fuels. On November 1, 1989, all gasoline tanks, dispenser islands, and associated piping were removed from the site. Subsequently, soil borings were advanced and samples were collected and analyzed. This previous Phase I assessment work /scr ¡C:WORKPLAN¡PENCEXNV.WKP 8 e e has partially delineated the plume, upon review the County is requiring additional Phase II characterization. RESPONSIBILITY OF KEY PERSONNEL: All personnel on-site will have assigned responsibilities. Mr. Phil Goalwin, R.G. of AquaGeosciences, Inc. will serve as Project Manager and On-Site Geologist. He will also serve as site Safety Officer (SSO). As SSO, Mr. Goalwin will ensure that on-site personnel have received a copy of the 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 SSO. Appropriate personal protective equipment, listed below, will be used. The SSO 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 ensuring sample integrity by adherence to Chain-of-Custody protocol. On-site employees will take reasonable precautions to avoid unforseen 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 wi th 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 Iser. IC: liJORKPLAN IPENCErNV. WKP 9 e e action levels as determined using PID. Action levels requ1r1ng 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 as they are moderately to extremely toxic and most are highly flammable. Threshold Limit Values (TLV'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 100 150 5000 Xylene 100 150 4300 Benzene is considered an extreme cancer hazard. EXPOSURE MONITORING PLAN: A Photo-Ionization Detector (PID) will be used to monitor vapor concentrations around site. Should concentrations exceed TLV'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 EOUIPMENT: 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. A set of cones, placards, or wide yellow tape, surrounding the site will define perimeter. The Project Manager will be responsible for site security. DECONTAMINATION 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. Isor IC:WORKPLAH/PENCErNV.WKP 10 e e All personnel will be advised to wash their hands, neck, and face wi th 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. 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 steam-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 REOUIREMENTS: The SSO will conduct a pre-site training session which will include all points of MSDS forms, contaminant properties, warning signs, health hazard data, risk for exposure, and emergency first aid. All chemicals expected to be encountered will be covered and the SSO will ensure 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 Iser IC:WORKPLAN/PENCEXNV.WKP 11 e e 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 numbers of employees, medical evaluations, on-the-job logs from entry to exit, first aid administered, visits on-site by outside persons, and personal air monitoring records. CONTINGENCY PLANS: In the event of accident, injury, or other emergency, the Project Director, Senior project Manager, or other person will notify appropriate government agencies or individuals as follows: 1.

Trux~on Avenue, Bakersfield, California (Figure 1). The si~e is loca~ed eas~ of Beale Avenue, be~ween Eas~ Trux~on Avenue and Eas~ 18~h S~ree~ and is si~ua~ed in Sec~ion 29, Township 29 Sou~h, Range 28 Eas~, Moun~ Diablo Baseline and Meridian. A.P.N. 017-160-07. SITE HISTORY: The subjec~ parcel is owned by Pence Pe~roleum Company and was previously opera~ed as Pence Au~oma~ed Fuels. On November 1, 1989, soil samples were ~aken under three underground fuel s~orage ~anks and service pump island (Figure 2) in the following manner: The sou~h ~ank was a 600 gallon leaded regular gasolinø s~orage ~ank. Sample number P1, P2, P3, and P4 were taken a~ the loca~ion shown on the tes~hole boring loca~ion map (Figure 2). The center tank was a 600 gallon premium unleaded gasoline storage tank. Sample numbers PS, P6, P7, and pa were taken a~ the loca~ion shown on the tes~hole boring location map (Figure 2). The nor~h ~ank was a 10,000 gallon unleaded gasoline s~orage tank. Sample numbers P9, P10, P11, and P12 were taken a~ the locations shown on the ~es~hole boring location map (Figure 2). 1 e e The service pump island was sampled in two locations (Figure 2). The alpha numeric designations for these soil samples are P13, P14, P15, and P16. Each location beneath the underground fuel tanks and dispenser island was sampled at depth of 2 feet and 6 feet. The sampling was conducted by MP Vacuum of Bakersfield, California. Laboratory analysis on soil samples was conducted by BC Laboratories, Inc. of Bakersfield, California from November 2, 1989, to November 9, 1989, when the soil sample analysis was completed. The results of the laboratory analysis indicated the presence of petroleum constituents concentrated at the P5, P6, P9, and PIO soil sample locations (Figure 2). Benzene levels ranged from 2.4 ppm in soil sample P9 to 58.81 ppm in soil sample P6. Benzene levels of .28 ppm and .38 ppm were found to be in soil sample PI and P2 respectively. Benzene levels were found to be non-detectable in all other soil samples. Total Petroleum Hydrocarbons (T.P.H.) levels in soil samples ranged from non-detectable to 8,843.63 ppm. Again the higher levels of T.P.H. were found to be concentrated in the area of soil samples P5, P6, P9, and P10. As a resul t of these 1 eve 1 s of petro 1 eum constituents in soi 1 samples, Pence Petroleum Company was required to provide a site characterization work plan proposal pursuant to a letter sent from e e the Resource Management Agency, Departmen~ of Environmental Services on March 2, 1990, to Pence Petroleum Company. SCOPE OF WORK: The work to be provided will be conducted in accordance with the California LUFT Manual Recommendations, E.P.A. Regulations, A.S.T.M. Test Methods and Kern County Health Department Requirements. Work specified at the site involves soil boring and soil sampling. Additional water information will be collected if it is determined that ground water may have been impacted by petroleum constituents originating from this site as a result of our field investigation. FIELD INVESTIGATION PREPARATION: -J Underground utility locations will be located and marked at the site by Underground Services Alert (USA) prior to drilling operations. Testhole borings will be probed to a depth of four (4) feet to further alleviate the possibility of damaging any underground utilities or obstructions. Any obstructions that may interfere with access to testhole boring locations will be moved or relocated, if necessary, prior to the field investigation. GROUND WATER: The estimated depth to grÞùnd· wate~, below the site, is approximately H18.5 to 200 feet ~elow ground surface. The nearest e e water wells in the area are located as follows: one well between Baker street and Kern street with the depth to water 184'; one well on Beale Avenue, north of California Blvd. with the depth to water 186'; and one well between Tulare Street and Kern Street in the Truxton area with the depth to water 200'. This information was provided by California Water Services on April 27, 1989. The regional ground water gradient is to the southwest, per information furnished by the Kern County Water Agency (Tom Haslebacher). SUMMARY OF FIELD INVESTIGATION: Number of testhole borings '-~e propose to drill 3 testhole borings located in the immediate area of the three (3) previously removed fuel tanks and fuel dispenser island. See attached testhole boring location map for proposed testhole boring locations (Figure 2). One testhole boring (B1) will be located in the vicinity where the highest levels of petroleum constituents were indicated as a result of laboratory analysis of P5 and P6. The remaining 2 testholes will be situated around the perimeter as follows: Testhole boring B2 will be positioned to indicate the levels of petroleum constituents southwest of Testhole Boring Bl. Soil samples taken under the 600 gallon leaded regular gasoline tank indicated levels of T.P.H. to be substantially dropping in samples taken at 2 feet to samples taken at 6 feet below the bottom of the 4 e e tank. The Benzene levels, as well as other petroleum constituents, were also dropping or non-detectable. This would indicate this area was impacted by petroleum constituents as a result of overspilling during the tank filling process. This testhole boring is located to determine the boundaries of the petroleum constituents concentrated around Testhole Boring Bl and serve as a check for petroleum constituents at greater depths originating ('L.. I from the south 600 gallon underground fuel tank. Testhole Boring B3 is located northeast of Testhole Boring Bl and is positoned to serve two purposes in the same manner as Testhole Boring B2. Laboratory analysis of soil samples P13, P14, P15, and P16 indicated non-detectable levels of Benzene with T.P.H. levels being relatively low with respect to levels at Testhole Boring Bl. These levels could indicate that petroleum constituents impacted these so i 1 samp 1 es as a resul t of site wash-down or gaso 1 ine spi llage during service pump maintenance (fi 1 ter changes). The primary purposes of this testhole boring would be to determine if a leak occurred in the area of the fuel dispenser island near the east end. Soil sample P6 indicated a T.P.H. level of 65.55 with a non-detectable Benzene level. The secondary purpose would be to determine if the petroleum constituent concentrated at Testhole Boring Bl extend in this easterly direction at greater depths. 5 e e DRILLING METHOD: TESTHOLE SOIL BORINGS AND FIELD SAMPLING GUIDELINES ,.I '/ " '. \ :Ì'... "-~4"~ We propose to use a truck-moun1;ed Mobile B-80 drill rig with 8 1/2" outside diameter, 4 1/4" I.D. hollow stem augers AASHTO Designation· T251-77. The augers will be steam cleaned prior to drilling each testhole at the site. Total Depth of Testhole Borings The total depth will not extend through the first aquifer encountered. The upper most aquifer is expected to be at approximately 180 to 200 feet below ground surface. Field Soil Samplinq Procedures and Soil Classification Soi 1 samples wi 11 be collected at ~ foot de~interva..ls, as field conditions warrant, starting at 5 f~~~_~~l~w the ground surface. --------_.-_.~-- - ---~.---_. - --------------- The soil samples will be collected using a 2" inside diameter by 18" long split spoon sampler. Two inch outside diameter by 6" long brass sample tubes will be inserted into the sampler prior to use. The sample tubes will be pre-cleaned by steam and Trisodium Phosphate (T.S.P.) detergent wash and distilled water prior to use and stored in clean plastic bags before inserting into the sampler. The split spoon sampler will also be cleaned using the same methods, as previously described, between each sample interval. 6 e e After the soil sample is collected, the sample tube from the bottom of the sampler will be immediately sealed in the field by placing I I, teflon covers over the open end of the tube and placing a plastic cap over the teflon cover. An adhesive tape will be placed around the plastic cap to insure that the cap is secured and an airtight seal is maintained. All soil samples will be labeled appropriately in the field. Labels will include: sample location; depth; date; time; job number; and field identification number. Samples will be placed ,:s -"=",{ '=Y' . immediately in an insulated storage container containing blue ice. The temperature inside the storage container will be maintained at 4 degrees Celsiusj39.2 degrees Fahrenheit and monitored with a thermometer to insure that the temperature remains constant. A chain of custody record will accompany the samples. Chain of custody records will include: sample location; depth; date; time; job number; and field identification number, analysis required and personnel collecting samples. A field log book will be maintained containing essentially the same information as the chain of custody record with the addition of any field observations about the sample. The middle tube sample from the split spoon sampler or the soil from the sampler shoe will be placed in sealed glass containers. After approximately one half hour, a field reading will be ~aken using the H.N.U. 101 Photoionization Meter. The field readings will be recorded and used to determine the levels of fuel 7 e e contamination encountered in the testhole and also assist in selecting the soil samples to be analyzed in the laboratory. Soil samples will be delivered to B.C. Laboratories, Inc., a State Certified hazardous waste testing laboratory, within 24 hours after the sample is collected. The temperature will be maintained at 4 degrees Celsius in the insulated storage container prior to delivering to the laboratory. Once the samples are delivered to the laboratory, the chain of custody will be signed by the laboratory indicating that possession of the samples has changed. The soil samples will be analyzed within the required 14-day period following collection, unless a 24 hour or 48 hour rush is required. Soils encountered at testhole borings will be logged and classified in accordance with the Unified Soil Classification System during drilling operations. Standard penetration blow counts will be recorded during soil sampling. The standard penetration test would consist of using a 140 pound drop hammer falling a distance of 30 inches to drive the sampler into the undisturbed soil and recording the number of blow counts required to drive the sampler each 6 inch increment. Personnel involved in collecting the soil samples and classifying the soils will be under the direct supervision of the project engineer and fully experienced in the field of environmental and geotechnical drilling. 8 e e Lithologic descriptions to be included in the borehole log are: Soil type; color; moisture description; grain size and shape; compactness or hardness; cohesiveness; grading; extent of weathering or fracturing; and sample odor. Drilling rates, standard penetration tests, HNU P.I. Meter readings, sample numbers and percent recovery of the samples wi 11 also by noted in the borehole field log. Testhole Boring Soil Containment and Abandonment During drilling operations, the soil cuttings will be placed on and covered with 4 mil. black plastic. ~~ ~=- The soi 1 cuttings wi 11 remain on-site in an area that is not accessible to the public. The soil cuttings will be labeled indicating the boring number and estimated depth of soil cuttings. After the augers are removed, the testho 1 e boreho 1 es wi 11 be backfilled with a 7-sack sand cement slurry. The soil cuttings will remain on-site until laboratory test results on soil samples are available. After review of the laboratory test results, appropriate disposal of the soil in each, barrel can be determined. Our field investigation will be conducted in accordance with approved State of California LUFT Manual Recommendations, E.P.A. and Kern County Health Department Regulations and A.S.T.H. Test Methods. 9 e e GRAB GROUND WATER SAMPLING PROCEDURES If it is determined that ground water has been impacted by gasoline, a grab sample will be collected through the hollow stem augers. A 1.7 x 3.0 acrylic bailer will be used to collect the sample. The augers will be raised approximately 5 feet to allow water to enter the borehole prior to collecting the water sample. The water sample will be transferred into 2 sterilized glass, 40 mI. V.O.A. sample containers. The sample will be immediately sealed in the field insuring that no air bubbles occur after the container lid is placed over the sample containers. The samples will be labeled appropriately in the field. Labels will include: Sample location; depth; date; time; job number; and field identification number. Samples will be placed immediately in an insulated storage container containing blue ice. The temperature inside the storage container wi 11 be maintained at 4 degrees Ce 1 s ius /39.2 degrees Fahrenheit and monitored with a thermometer to insure that the temperature remains constant. The storage container wi 11 al so include a laboratory prepared travel blank to insure that cross contamination does not occur. The travel blank will be placed in with the sample containers and will be analyzed if the water samples indicate detectable levels of gasoline fuel constituents. A chain of custody record will accompany the samples. Chain of custody records will include: Sample location; depth; date; time; job number; field identification number; analysis required and 1n e e personnel collecting samples. A field log book wilJ be maintained containing essentially the same information as the chain of custody record with the addition of any field observations about the sample. Q Water samples will be delivered to a state Certified hazardous ¡ . waste testing laboratory wi thin 24 hours after the sample is collected. The temperature will maintained 4 degrees at be Celsiusj39.2 degrees Fahrenheit in the insulated storage container prior to delivery to the laboratory. Once the samples are delivered to the laboratory, the chain of custody will be signed by the laboratory indicating that possession of the samples has changed.

Harris R.C.E. 15342, Exp. 3-31-93 13 e e REVISED HEALTH AND SAFETY PLAN FOR PENCE PETROLEUM COMPANY N.E. CORNER OF BEALE AVENUE AND EAST TRUXTUN BAKERSFIELD, CALIFORNIA GENERAL STATEMENT The site characterization for Pence Petroleum Company, 901 E. Truxtun, Bakersfield, California is being conducted to assess the vertical and latereal limits of on-site soil contamination. For preliminary assessment of contamination, three (3) testhole borings will be drilled. The soil sampling program will include soil cores, chemical analyses, grab samples, soil moisture measurements, and field screening by photoionization detector (PID). Detailed descriptions of borehole and drilling information will also be maintained. Decontamination procedures and heal th and safety measures conforming to Leve 1 D will be followed. Results from data analyses will be the basis of planning the subsequent investigation phase. 14 e e HAZARD EVALUATION This hazard evaluation is directed toward those volatile organic compounds which based on data gathered to date, are known or suspected to be present at sampling locations, they being: Benzene, Ethylbenzene, Toluene, Total Xylenes, Isopropylbenzene, Total Petroleum Hydrocarbons, Organic Lead, and Ethylene Dibromide. The U.S. Environmental Protection Agency (EPA) (1985) had defined levels of protection in order to provide a standard vocabulary to describe personal protection equipment. The four levels afford varying degrees of respiratory protection, dermal protection, and protection from traumatic injury. The four levels are summarized as follows: Level A consists of a totally encapsulated, chemically protective suit with self-contained breathing apparatus. Level B provides maximal respiratory protection through use of supplied air or self-contained breathing apparatus; the level of dermal protection is selected on the basis of anticipated hazards. Level C incorporates an air-purifying respirator which is specific to the contaminant(s) of concern; the degree of dermal protection depends on anticipated dermal hazards. Level D is basically a work uniform including hard hats, gloves and safety boots. 15 e e If the Safety Supervisor determines that hazardous or potentially hazardous conditions exist they may require upgrading of the protection level from Level D to Level C. The Safety Supervisor also has the authority to stop. all sampling-related work until adequate protection is provided for all workers, or until site hazards are mitigated. Safety equipment required for Leve 1 C includes air purifying respirators, chemical resistant clothing, gloves, boot covers, and hard hats. The Safety Supervisor may require the use of portable field monitoring equipment such as an organic vapor analyzer in order to determine whether respiratory protection is necessary. The fo 11 owing sections of the Heal th and Safety P Ian describe safety equipment, decontamination procedures, and work limitations for sampl ing operations under Protection Leve I D. Emergency procedures in the event of personal exposure, injury, or explosion are also included for all operations, regardless of protection level. A separate section is provided describing Protection Level C safety equipment, decontamination procedures, personal precautions and site access. Protection Level C procedures will be followed if the Safety Supervisor determines that site hazards or potential site hazards warrant this level of protection. 16 e e SAFETY EQUIPMENT Safety equipment required for Protection Level D includes hard hats and boots. Hard hats will be worn during all drilling operations. Additional equipment available to the investigative team includes earplugs, disposable coveralls and boots, chemical-resistant gloves, and safety goggles. Use of this additional equipment shall be determined by the Safety Supervisor based on site conditions. EQUIPMENT The following equipment will be available for Protection Level D work: Protective Clothing AF-15 Pioneer nitrile gloves Tyvek coveralls, hoods, and boots Visual Uvex #9300 dust & chemical goggles Hearing Moldex pura-foam ear plugs Miscellaneous 16 unit first aid kit Barrier cream Hard hats· . Hard hats are mandatory during all drilling operations. 17 e e DECONTAMINATION AND DISPOSAL Although the hazard evaluation indicated that harmful exposure to hazardous compounds in soils or groundwater is not likely to occur during the investigation, personnel decontamination accomplished by good personal hygiene practices should be followed to limit potential exposure to contaminants. Personnel decontamination is required prior to all breaks and meals, and at the end of the day. Decontamination of individuals will be accomplished by soap and water washing followed by a clean water rinse. When used, protective clothing, gloves, or goggles will be removed and stored in plastic bags prior to all breaks and meals. At the end of the day, disposable gloves, coveralls, and boots will be collected in plastic bags for disposal, and non-disposable protective equipment such as safety goggles will be decontaminated by soap and water washing followed by a clean water rinse. Procedures for disposal of investigation-derived materials have been established in accordance with federal and state hazardous waste regulations. Investigation-derived materials include soil cuttings and development water from monitor well drilling operations. If waste derived from investigation activities are determined by laboratory analysis to be hazardous, then disposal of those wastes will be conducted in compliance with EPA's interim policy "Procedure for Planning and Impl ementing Off-s i te Response Actions" (Federal Register, 1985), as follows: 18 e e Trea tment . .}Î " t) of-=- . Treatment, reuse, or recycling of hazardous wastes will be considered in the removal of investigation-derived hazardous materials. Selection of Off-site Treatment or Disposal Facility Selection of an appropriate facility for off-site management of investigation-derived hazardous wastes will be based on the following requirements: 1. The owner or operator of any hazardous waste management facility under consideration must have a RCRA permit applicable to specific wastes and specific storage, treatment, or disposal processes. 2. A RCRA compliance inspection must be performed at the off-site fac i 1 i ty to receive investigation-derived hazardous wastes not more than six months before receiving such wastes. 3. Any land disposal facility receiving investigation-derived hazardous wastes must meet RCRA minimum technical requirements per the Hazardous and Solid Waste Amendments of 1984. These technical requirements include ground water monitoring and liner and leachate collection system standards. 19 e e Manifest Requirements. r;L! ,:.;' i'!' .z:;;:;Y 11'@ Investigation-derived hazardous material transported to an off-site storage, treatment, or disposal site wi 11 be accompanied by a Uniform Hazardous Waste Manifest, in compliance with requirements in the Code of Federal Regulations, 40 CFR 262. 20 e e PERSONAL PRECAUTIONS Eating, drinking, chewing gum or tobacco, smoking, or any practice that increases the probabi 1 i ty of hand-to-mouth transfer and ingestion of material should be avoided during drilling and soil sampling activities. Hands and face should be thoroughly washed upon leaving the work area. Contact with contaminated or suspected contaminated surfaces should be avoided. Whenever possible, do not walk through puddles, leachate, or discolored surfaces; kneel on ground; or lean, sit, or place equipment on drums, containers, or the ground. Medicine and alcohol can magnify the effects from exposure to toxic chemicals. Prescribed drugs should not be taken by personnel unless specifically approved by a qualified physician. 21 e e EMERGENCY PROCEDURES IN THE EVENT OF PERSONAL EXPOSURE Call the Safety Supervisor to the scene immediately. Immediately remove any clothing that becomes contaminated. Promptly wash with soap and flush with clean water. Determine the material involved. Don't expose self or others to the materials unnecessarily. Stay upwind, control access to the area, and wear the appropriate protective equipment. Remove people from the contaminated area. Wear the appropriate protective equipment and don't charge in blindly. Administer first. aid, in necessary. If the incident warrants, the Safety Supervisor must call the appropriate emergency services. See the list of emergency phone numbers in the next section. The emergency care facilities are indicated on Figure lA. Record information on the exposure. IN THE EVENT OF PERSONAL INJURY Call the Safety Supervisor to the scene immediately. Remove people from dangerous area or eqùipment. Administer first aid, if necessary. 22 e e If ~he inciden~ warran~s, ~he Safe~y Supervisor mus~ call ~he appropria~e emergency services. See ~he lis~ of emergency phone numbers in ~he next sec~ion. The emergency care facili~ies are indica~ed on Figure lA. IN THE EVENT OF FIRE OR EXPLOSION Evacua~e personnel from area of danger. Call ~he Safe~y Supervisor ~o ~he scene immedia~ely. Adminis~er firs~ aid if necessary. The Safe~y Supervisor shall: No~ify the Fire Department. Con~ac~ the local hospital immediately when a major fire s~arts, advising ~hem of the chemicals involved and the Poison Control Cen~er to be contacted. Keep personnel out of the smoke or mist created by the fire and hose streams. Immediately evacuate areas in the path of smoke.

Truxton Avenue, Bakersfield, California (Figure 1). The site is located east of Beale Avenue, between East Truxton Avenue and East 18th Street and is situated in Section 29, Township 29 South, Range 28 East, Mount Diablo Baseline and Meridian. A.P.N. 017-160-07. SITE HISTORY: The subject parcel is owned by Pence Petroleum Company and was previously operated as Pence Automated Fuels. On November 1, 1989, soil samples were taken under three underground fuel storage tanks and service pump island (Figure 2) in the following manner: The south tank was a 600 gallOn~regUlar gasoline storage tank. Sample number P1, P2, P3, and P4 were taken at the location shown on the testhole boring location map (Figure 2). The center tank was a 600 gallon premium,~n~ded gasoline storage tank. Sample numbers P5, P6, P7, and P8 were taken at the location shown on the testhole boring location map (Figure 2). The north tank was a 10,000 gallon unleaded gasoline storage tank. ~ Sample numbers P9, P10, P11, and P12 were taken at the locations shown on the testhole boring location map (Figure 2). 1 e e The service pump island was sampled in two locations (Figure 2). The alpha numeric designations for these soil samples are P13, P14, P15, and P16. Each location beneath the underground fuel tanks and dispenser island was sampled at depth of 2 feet and 6 feet. The sampling was conducted by MP Vacuum of Bakersfield, California. Laboratory analysis on soil samples was conducted by BC Laboratories, Inc. of Bakersfield, California from November 2, 1989, to November 9, 1989, when the soil sample analysis was completed. The results of the laboratory analysis indicated the presence of petroleum constituents concentrated at the P5, P6, P9, and P10 soil sample locations (Figure 2). Benzene levels ranged from 2.4 ppm in soil sample P9 to 58.81 ppm in soil sample P6. Benzene levels of .28 ppm and .38 ppm were found to be in soil sample P1 and P2 respectively. Benzene levels were found to be non-detectable in all other soil samples. Total Petroleum Hydrocarbons (T.P.H.) levels in soil samples ranged from non-detectable to 8,843.63 ppm. Again the higher levels of T.P.H. were found to be concentrated in the area of soil samples P5, P6, P9, and P10. As a result of these levels of petroleum constituents in soil samples, Pence Petroleum Company was required to provide a site characterization work plan proposal pursuant to a letter sent from .. e e the Resource Management Agency, Department of Environmental Services on March 2, 1990, to Pence Petroleum Company. SCOPE OF WORK: The work to be provided will be conducted in accordance with the California LUFT Manual Recommendations, E.P.A. Regulations, A. S . T. M. Test Methods and Kern County Health Department Requirements. Work specified at the site involves soil boring and soil sampling. Additional water information will be collected if it is determined that ground water may have been impacted by petroleum constituents originating from this site as a result of our field investigation. FIELD INVESTIGATION PREPARATION: Underground utility locations ~ill be located and marked at the site by Underground Services Alert (USA) prior to drilling operations. Testhole borings will be probed to a depth of four (4) feet to further alleviate the possibility of damaging any underground utilities or obstructions. Any obstructions that may interfere with access to testhole boring locations will be moved or relocated, if necessary, prior to the field investigation. GROUND WATER: The estimated depth to ground water, below the approximately 185 to 200 feet below ground surface. site, is The nearest e e water wells in the area are located as follows: one well between Baker street and Kern street with the depth to water 184'; one well on Beale Avenue, north of California Blvd. with the depth to water 186'; and one well between Tulare street and Kern street in the Truxton area with the depth to water 200'. This information was provided by California Water Services on April 27, 1989. SUMMARY OF FIELD INVESTIGATION: Number of testhole borings We propose to drill 4 testhole borings located in the immediate area of the three (3) previously removed fuel tanks and fuel dispenser island. See attached testhole boring location map for proposed testhole boring locations (Figure 2). One testhole boring (B1) will be located in the vicinity where the highest levels of petroleum constituents were indicated as a result of laboratory analysis of P5 and P6. The remaining 3 testholes will be situated around the perimeter as follows: Testhole boring B2 will be positioned to indicate the levels of petroleum constituents southwest of Testhole Boring B1. Soil samples taken under the 600 gallon leade~regular gasoline tank indicated levels of T.P.H. to be substantially dropping in samples taken at 2 feet to samples taken at 6 feet below the bottom of the -1 tank. ~ The Benzene levels, as well as other petroleum constituents, were also dropping or non-detectable. This would indicate this area was impacted by petroleum constituents as a result of ì overspilling during the tank filling process'4 This testhole boring ,~v~ e e is located to determine the boundaries of the petroleum constituents concentrated around Testhole Boring Bl and serve as a check for petroleum constituents at greater depths originating from the south 600 gallon underground fuel tank. Testhole Boring B3 is located to serve two purposes in the same manner as Testhole Boring B2. Laboratory analysis of soil samples P13, P14, P15, and P16 indicated non-detectable levels of Benzene with T.P.H. levels being relatively low with respect to levels at Testhole Boring Bl. These levels could indicate that petroleum constituents impacted these soil samples as a result of site wash-down or gasoline spillage during service pump maintenance (filter changes). The primary purposes of this testhole boring would be to determine if a leak occurred in the area of the fuel dispenser island near the east end. Soil sample P6 indicated a T.P.H. level of 65.55 with a non-detectable Benzene level. The secondary purpose would be to determine if the petro 1 eum constituent concentrated at Testho 1 e '{ '-6kt '7 Boring Bl extend in this easterly direction at greater depths.~ ~' ~~ ' 1"~ _ .¡...'fJ <:- '")1'-,' Testhole Boring B4 is located to the north of Testhole Boring Bl is positioned to serve two purposes in the same manner as Testhole Borings B2 and B3. Laboratory analysis on soil samples Pll and P12 indicate non-detectable levels of Benzene and T.P.H., therefore, it can be assumed that a gasoline leak in this area has not occurred. However, petroleum constituent levels increase from 2.4 ¡ - I <¡ e e \ \ /VJJ/ 3491.08 ppm of ppm to 10.63 ppm of Benzene, and 1719.31 ppm to T.P.H as you go from 2 feet to 6 feet below ground surface. The primary purpose of Testhole Boring B4 is to determine if the petroleum constituents in the vicinity of sample locations P? and P10 have extended this far to the north. The secondary purpose of Testhole Boring B4 is to determine if the petroleum constituents concentrated in the vicinity of Testhole Boring Bl have extended this far to the north at greater depths. It may become necessary to modify the location of testhole borings in the field to expand the assessment study area if HNU 101 Photoionization Meter levels on soil samples indicate the petroleum constituent plume limits are not being defined. The study area will be expanded by relocating the testhole borings outward from Testhole Boring B1 to 10 foot increments. .......... ~~'-...,. .~ i ',.../ --. \ v-" -\ \V-) ",,\ //'" ::y'" ,. -, .. ., ./ .~ ,~ -- '.Ì e e TESTHOLE SOIL BORINGS AND FIELD SAMPLING GUIDELINES DRILLING METHOD: We propose to use a truck-mounted Mobile B-80 drill rig with 8 1/2" outside diameter, 4 1/4" I.D. hollow stem augers AASHTO Designation T251-77. The augers will be steam cleaned prior to drilling each testhole at the site. Total Depth of Testho1e Borings The total depth will not extend through the first aquifer encountered. The upper most aquifer is expected to be at approximately 180 to 200 feet below ground surface. Field Soil Sampling Procedures and Soil Classification Soil samples will be collected at 5 foot and 10 foot depth intervals, as field conditions warrant, starting at 10 feet below '-- , the ground surface. The sQi1 sample.~ will be collected using a 2" --- __ ,~ r~Cj\()-~ inside diameter by 18~ong split spoon sampler. Two inch outside diameter by 6" long brass sample tubes will be inserted into the sampler prior to use. The sample tubes will be pre-cleaned by steam and Trisodium Phosphate (T.S.P.) detergent wash and distilled water prior to use and stored in clean plastic bags before inserting into the sampler. The split spoon sampler will also be cleaned using the same methods, as previously described, between each sample interval. I - 7 I~ / e e After the soil sample is collected, the sample tube from the bottom of the sampler will be immediately sealed in the field by placing teflon covers over the open end of the tube and placing a plastic cap over the teflon cover. An adhesive tape will be placed around the plastic cap to insure that the cap is secured and an airtight seal is maintained. All soil samples will be labeled appropriately in the field. Labels will include: sample location; depth; date; time; job number; and field identification number. Samples will be placed immediately in an insulated storage container containing blue ice. The temperature inside the storage container will be maintained at 4 degrees Celsiusj39.2 degrees Fahrenheit and monitored with a thermometer to insure that the temperature remains constant. A chain of custody record wi 11 accompany the sampl es. Chain of custody records will include: sample location; depth; date; time; job number; and field identification number, analysis required and personnel collecting samples. A field log book will be maintained containing essentially the same information as the chain of custody record with the addition of any fie Id observations about the sample. The middle tube sample from the split spoon sampler or the soil from the sampler shoe will be placed in sealed glass containers. After approximately one half hour, a field reading will be taken using the R.N.V. 101 Photoionization Meter. The field readings will be recorded and used to determine the levels of fuel e e contamination encountered in the testhole and also assist in selecting the soil samples to be analyzed in the laboratory. Soil samples will be delivered to B.C. Laboratories, Inc., a State ------ -' Certified hazardous waste testing laboratory, within 24 hours after the sample is collected. The temperature will be maintained at 4 degrees Celsius in the insulated storage container prior to delivering to the laboratory. Once the samples are delivered to the laboratory, the chain of custody will be signed by the laboratory indicating that possession of the samples has changed. The soil samples will be analyzed within the required 14-day period following collection, unless a 24 hour or 48 hour rush is required. Soils encountered at testhole borings will be logged and classified in accordance with the Unified Soil Classification System during drilling operations. Standard penetration blow counts wi 11 be recorded during soil sampling. The standard penetration test would consist of using a 140 pound drop hammer falling a distance of 30 inches to drive the sampler into the undisturbed soil and recording the number of blow counts required to drive the sampler each 6 inch increment. Personnel involved in collecting the soil samples and classifying the soils will be under the direct supervision of the project engineer and fully experienced in the field of environmental and geotechnical drilling. e e Lithologic descriptions to be included in the borehole log are: Soil type; color; moisture description; grain size and shape; compactness or hardness; cohesiveness; grading; extent of weathering or fracturing; and sample odor. Drilling rates, standard penetration tests, HNU P.I. Meter readings, sample numbers and percent recovery of the samples will also by noted in the borehole field log.

A 1.7 x 3.0 acrylic bailer will be used to collect the sample. The augers will be raised approximately 5 feet to allow water to enter the borehole prior to collecting the water sample. The water sample will be transferred into 2 sterilized glass, 40 mI. V.O.A. sample containers. The sample will be immediately sealed in the field insuring that no air bubbles occur after the container lid is placed over the sample containers. The samples will be labeled appropriately in the field. Labels will include: Sample location; depth; date; time; job number; and field identification number. Samples will be placed immediately in an insulated storage container containing blue ice. The temperature inside the storage container will be maintained at 4 degrees Celsius/39.2 degrees Fahrenhei t and monitored with a thermometer to insure that the temperature remains constant. The storage container wi 11 al so include a laboratory prepared travel blank to insure that cross contamination does not occur. The travel blank will be placed in with the sample containers and will be analyzed if the water samples indicate detectable levels of gasoline fuel constituents. A chain of custody record will accompany the samples. Chain of custody records will include: Sample location; depth; date; time; job number; field identification number; analysis required and 11 e e personnel collecting samples. A field log book will be maintained containing essentially the same information as the chain of custody record with the addition of any fie ld observations about the sample. Water samples will be delivered to a state Certified hazardous waste testing laboratory wi thin 24 hours after the sample is collected. The temperature will be maintained at 4 degrees Celsius/39.2 degrees Fahrenheit in the insulated storage container prior to delivery to the laboratory. Once the samples are delivered to the laboratory, the chain of custody will be signed by the laboratory indicating that possession of the samples has changed. The water samples will be analyzed with the required 7-day period following collection unless a 24 hour or 48 hour rush is required. I - e e LABORATORY ANALYSIS: Soil and water samples collected from the testholes/ground water grab samples will be transferred to a State Certified Laboratory to perform the analysis required. Selected soil samples will be analyzed by B.C. Laboratories, Inc., of Bakersfield, CA.

Harris R.C.E. 15342, Exp. 3-31-93 e e HEALTH AND SAFETY PLAN FOR PENCE PETROLEUM COMPANY N.E. CORNER OF BEALE AVENUE AND EAST TRUXTON BAKERSFIELD, CA GENERAL STATEMENT The site characterization for Pence Petroleum Company, 901 E. Truxton, Bakersfield, California is being conducted to assess the vertical and lateral limits of on-site soil contamination. For preliminary assessment of contamination, four ~es~bOringS will be drilled. The soil sampling program will include soil cores, chemical analyses, grab samples, soil moisture measurements, and field screening by photoionization detector (PID). Detailed descriptions of borehole and drilling information will also be maintained. Decontamination procedures and heal th and safety measures conforming to Level D will be followed. Results from data analyses will be the basis of planning the subsequent investigation phase. I . 15 e e HAZARD EVALUATION This hazard evaluation is directed toward those volatile organic compounds which based on data gathered to date, are known or suspected to be present at sampling locations, they being: Benzene, Ethylbenzene, Toluene, Total Xylenes, Isopropylbenzene, Total Petroleum Hydrocarbons, Organic Lead, and Ethylene Dibromide. The U.S. Environmental Protection Agency (EPA) (1985) had defined levels of protection in order to provide a standard vocabulary to describe personal protection equipment. The four I eve I safford varying degrees of respiratory protection, dermal protection, and protection from traumatic injury. The four levels are summarized as follows: Level A consists of a totally encapsulated, chemically protective suit with self-contained breathing apparatus. Level B provides maximal respiratory protection through use of supplied air or self-contained breathing apparatus; the level of dermal protection is selected on the basis of anticipated hazards. Level C incorporates an air-purifying respirator which is specific to the contaminant(s) of concern; the degree of dermal protection depends on anticipated dermal hazards. Level D is basically a work uniform including hard hats, gloves and safety boots. 16 e e If the Safety Supervisor determines that hazardous or potentially hazardous conditions exist, they may require upgrading of the protection level from Level D to Level C. The Safety Supervisor al so has the authority to stop all sampl ing-related work unti 1 adequate protection is provided for all workers, or until site hazards are mitigated. Safety. equipment required for Level C includes air purifying respirators, chemical resistant clothing, gloves, boot covers, and hard hats. The Safety Supervisor may require the use of portable field monitoring equipment such as an organic vapor analyzer in order to determine whether respiratory protection is necessary. The following sections of the Heal th and Safety Plan describe safety equipment, decontamination procedures, and work limitations for sampl ing operations under Protection Level D. Emergency procedures in the event of personal exposure, injury, or explosion are also included for all operations, regardless of protection level. A separate section is provided describing Protection Level C safety equipment, decontamination procedures, personal precautions and site access. Protection Level C procedures will be followed if the Safety Supervisor determines that site hazards or potential site hazards warrant this level of protection. e e SAFETY EQUIPMENT Safety equipment required for Protection Lev~l D includes hard hats and boots. Hard hats will be worn during all drilling operations. Additional equipment available to the investigative team includes earplugs, disposable coveralls and boots, chemical-resistant gloves, and safety goggles. Use df this additional equipment shall be determined by the Safety Supervisor based on site conditions. EQUIPMENT The following equipment will be available for Protection Level D work: Protective Clothing AF-15 Pioneer nitrile gloves Tyvek coveralls, hoods, and boots Visual Uvex #9300 dust & chemical goggles Hearing Moldex pura-foam ear plugs Miscellaneous 16 unit first aid kit Barrier cream Hard hats~ ~ Hard hats are mandatory during all drilling operations. e e DECONTAMINATION AND DISPOSAL Although the hazard evaluation indicated that harmful exposure to hazardous compounds in soils or groundwater is not likely to occur during the investigation, personnel decontamination accomplished by good personal hygiene practices should be followed to I imi t poten"tial exposure to contaminants. Personnel decontamination is required prior to all breaks and meals, and at the end o~ the day. Decontamination of individuals will be accomplished by soap and water washing followed by a clean water rinse. When used, protective clothing, gloves, or goggles will be removed and stored in plastic bags prior to all breaks and meals. At the end of the day, disposable gloves, coveralls, and boots will be collected in plastic bags for disposal, and non-disposable protective equipment such as safety goggles will be decontaminated by soap and water washing followed by a clean water rinse. Procedures for disposal of investigation-derived materials have been established in accordance with federal and state hazardous waste regulations. Investigation-derived materials include soil cuttings and development water from monitor well drilling operations. If waste derived from investigation activities are determined by laboratory analysis to be hazardous, then disposal of those wastes will be conducted in compliance with EPA's interim policy "Procedure for Planning and Implementing Off-site Response Actions" (Federal Register, 1985), as follows: e e Treatment Treatment, reuse, or recycling of hazardous wastes will be considered in the removal of investigation-derived hazardous materials. Selection of Off-site Treatment or Disposal Facility Selection of an appropriate facility for off-site management of investigation-derived hazardous wastes will be based on the following requirements: 1. The owner or operator of any hazardous waste management facility under consideration must have a RCRA permit applicable to specific wastes and specific storage, treatment, or disposal processes. 2. A RCRA compliance inspection must be performed at the off-site facility to receive investigation-derived hazardous wastes not more than six months before receiving such wastes. 3. Any land disposal faci 1 i ty receiving investigation-derived hazardous wastes must meet RCRA minimum technical requirements per the Hazardous and Solid Waste Amendments of 1984. These technical requirements include ground water monitoring and liner and leachate collection system standards. e e Manifest Requirements Investigation-derived hazardous material transported to an off-site storage, treatment, or disposal site wi 11 be accompanied by a Uniform Hazardous Waste Manifest, in compliance with requirements in the Code of Federal Regulations, 40 CFR 262. e e PERSONAL PRECAUTIONS Eating, drinking, chewing gum or tobacco, smoking, or any practice that increases the probability of hand-to-mouth transfer and ingestion of material should be avoided during drilling and soil sampling activities. Hands and face should be thoroughly washed upon leaving the work area. Contact with contaminated or suspected contaminated surfaces should be avoided. Whenever possible, do not walk through puddles, leachate, or discolored surfaces; kneel on ground; or lean, sit, or place equipment on drums, containers, or the ground. Medicine and alcohol can magnify the effects from exposure to toxic chemicals. Prescribed drugs should not be taken by personnel unless specifically approved by a qualified physician. e - EMERGENCY PROCEDURES IN THE EVENT OF PERSONAL EXPOSURE Call the Safety Supervisor to the scene immediately. Immediately remove any clothing that becomes contaminated. Promptly wash with soap and flush with clean water. Determine the material involved. Don't expose self or others to the materials unnecessarily. stay upwind, control access to the area, and wear the appropriate protective equipment. Remove people from the contaminated area. Wear the appropriate protective equipment and don't charge in blindly. Administer first aid, in necessary. If the incident warrants, the Safety Supervisor must call the appropriate emergency services. See the I ist of emergency phone numbers in the next section. The emergency care facilities are indicated on Figure lA. Record information on the exposure. IN THE EVENT OF PERSONAL INJURY Call the Safety Supervisor to the scene immediately. Remove people from dangerous area or equipment. Administer first aid, if nec~ssary. e e If the incident warrants, the Safety Supervisor must call the appropriate emergency services. See the list of emergency phone numbers in the next section. The emergency care facilities are indicated on Figure lA. IN THE EVENT OF FIRE OR EXPLOSION Evacuate personnel from area of danger. Call the Safety Supervisor to the scene immediately. Administer first aid if necessary. The Safety Supervisor shall: Notify the Fire Department. Contact the local hospital immediately when a major fire starts, advising them of the chemicals involved and the Poison Control Center to be contacted. Keep personnel out of the smoke or mist created by the fire and hose streams. Immediately evacuate areas in the path of smoke.

Truxton Avenue, Bakersfield, California (Figure 1). The site is located east of Beale Avenue, between East Truxton Avenue and East 18th Street and is situated in Section 29, Township 29 South, Range 28 East, Mount Diablo Baseline and Meridian. A.P.N. 017-160-07. SITE HISTORY: The subject parcel i~ owned by Pence Petroleum Company and was previously operated as Pence Automated Fuels. On November 1, 1989, soil samples were taken under three underground fuel storage tanks and service pump island (Figure 2) in the following manner: The south tank was a 600 gallon leaded regular gasoline storage tank. Sample number P1, P2, P3, and P4 were taken at the location shown on the testhole boring location map (Figure 2). The center tank was a 600 gallon premium unleaded gasoline storage tank. Sample numbers PS, P6, P7, and P8 were taken at the location shown on the testhole boring location map (Figure 2). The north tank was a 10,000 gallon unleaded gasoline storage tank. Sample numbers P9, P10, Pll, and P12 were taken at the locations shown on the testhole boring location map (Figure 2). 1 e e The service pump island was sampled in two locations (Figure 2). I The alpha numeric designations for these soil samples are PI3, PI4, PIS, and P16. Each location beneath the underground fuel tanks and dispenser island was sampled at depth of 2 feet and 6 feet. The sampling was conducted by MP Vacuum of Bakersfield, California. Laboratory analysis on soil samples was conducted by BC Laboratories, Inc. of Bakersfield, California from November 2, 1989, to November 9, 1989, when the soil sample analysis was completed. The results of the laboratory analysis indicated the presence of petroleum constituents concentrated at the PS, P6, P9, and PI0 soil sample locations (Figure 2). Benzene levels ranged from 2.4 ppm in soil sample P9 to 58.81 ppm in soil sample P6. Benzene levels of .28 ppm and .38 ppm were found to be in soil sample PI and P2 respectively. Benzene levels were found to be non-detectable in all other soil samples. Total Petroleum Hydrocarbons (T.P.H.) levels in soil samples ranged from non-detectable to 8,843.63 ppm. Again the higher levels of T.P.H. were found to be concentrated in the area of soil samples PS, P6, P9, and P10. As a resul t of these levels of petroleum constituents in soi 1 samples, Pence Petroleum Company was required to provide a site characterization work plan proposal pursuant to a letter sent from e e '~he Resource Managemen~ Agency, Depar~men~ of Environmen~al Services on March 2, 1990, ~o Pence Pe~roleum Company. SCOPE OF WORK: The work ~o be provided will be conduc~ed in accordance wi~h ~he California LUFT Manual Recommenda~ions, E.P.A. Regula~ions, A. S . T. M. Tes~ Me~hods and Kern Coun~y Heal ~h Depar~men~ Requiremen~s. Work specified a~ ~he si~e involves soil boring and soil sampling. Addi~ional wa~er information will be collected if it is determined that ground wa~er may have been impacted by pe~roleum constituents originating from this site as a result of our field investiga~ion. FIELD INVESTIGATION PREPARATION: Underground utility locations will be located and marked at the site by Underground Services Alert (USA) prior to drilling operations. Testhole borings will be probed to a depth of four (4) feet to further alleviate the possibility of damaging any underground utilities or obstructions. Any obstructions that may interfere with access to testhole boring locations will be moved or relocated, if necessary, prior to the field investigation. GROUND WATER: The estimated depth to ground water, below the site, is approximately 185 to 200 fee~ below ground surface. The nearest e e water wells in the area are located as follows: one well between Baker street and Kern street with the depth to water 184'; onè well on Beale Avenue, north of California Blvd. with the depth to water 186'; and one well between Tulare street and Kern street in the Truxton area with the depth to water 200'. This information was provided by California Water Services on April 27, 1989. The regional ground water gradient is to the southwest, per information furnished by the Kern County Water Agency (Tom Haslebacher). SUMMARY OF FIELD INVESTIGATION: Number of testhole borings We propose to drill 3 testhole borings located in the immediate area 0 f the three ( 3 ) previ ous 1 y removed fue 1 tanks and fue 1 dispenser island. See attached testhole boring location map for proposed testhole boring locations (Figure 2). One testhole boring (B1) will be located in the vicinity where the highest levels of petroleum constituents were indicated as a result of laboratory analysis of P5 and P6. The remaining 2 testholes will be situated around the perimeter as follows: Testhole boring B2 will be positioned to indicate the levels of petroleum constituents southwest of Testhole Boring B1. Soil samples taken under the 600 gallon leaded regular gasoline tank indicated levels of T.P.H. to be substantially dropping in samples taken at 2 feet to samples taken at 6 feet below the bottom of the 4 e e tank. The Benzene levels, as well as other petroleum constituents, were also dropping or non-detectable. This would indicate this area was impacted by petroleum constituents as a result of overspilling during the tank filling process. This testhole boring is located to determine the boundaries of the petroleum constituents concentrated around Testhole Boring Bl and serve as a check for petroleum constituents at greater depths originating from the south 600 gallon underground fuel tank. Testhole Boring B3 is located northeast of Testhole Boring BI and is positoned to serve two purposes in the same manner as Testhole Boring B2. Laboratory analysis of soil samples PI3, PI4, PIS, and P16 indicated non-detectable levels of Benzene with T.P.H. levels being relatively low with respect to levels at Testhole Boring Bl. These levels could indicate that petroleum constituents impacted these soil samples as a result of site wash-down or gasoline spi llage during service pump maintenance (fi 1 ter changes). The primary purposes of this testhole boring would be to determine if a leak occurred in the area of the fuel dispenser island near the east end. Soil sample P6 indicated a T.P.H. level of 65.55 with a non-detectable Benzene level. The secondary purpose would be to determine if the petroleum constituent concentrated at Testhole Boring Bl extend in this easterly direction at greater depths. 5 e e TESTHOLE SOIL BORINGS AND FIELD SAMPLING GUIDELINES DRILLING METHOD: We propose to use a truck-mounted Mobile B-80 drill rig with 8 1/2" outside diameter, 4 1/4" I.D. hollow stem augers AASHTO Designation T251-77. The augers will be steam cleaned prior to drilling each testhole at the site. Total Depth of Testhole Borings The total depth will not extend through the first aquifer encountered. The upper most aquifer is expected to be at approximately 180 to 200 feet below ground surface. Field Soil Samplinq Procedures and Soil Classification Soil samples will be collected at 5 foot depth intervals, as field conditions warrant, starting at 5 feet below the ground surface. The soil samples will be collected using a 2" inside diameter by 18" long split spoon sampler. Two inch outside diameter by 6" long brass sample tubes will be inserted into the sampler prior to use. The sample tubes will be pre-cleaned by steam and Trisodium Phosphate (T.S.P.) detergent wash and distilled water prior to use and stored in clean plastic bags before inserting into the sampler. The split spoon sampler will also be cleaned using the same methods, as previously described, between each sample interval. 6 e e After the soil sample is collected, the sample tube from the bottom of the sampler will be immediately sealed in the field by placing teflon covers over the open end of the tube and placing a plastic cap over the tefloncover. An adhesive tape will be placed around the plastic cap to insure that the cap is secured and an airtight seal is maintained. All soil samples will be labeled appropriately in the field. Labels will include: sample location; depth; date; time; job number; and field identification number. Samples will be placed immediately in an insulated storage container containing blue ice. The temperature inside the storage container will be maintained at 4 degrees Celsiusj39.2 degrees Fahrenheit and monitored with a thermometer to insure that the temperature remains constant. A chain of custody record will accompany the samples. Chain of custody records will include: sample location; depth; date; time; job number; and field identification number, analysis required and personnel collecting samples. A field log book will be maintained containing essentially the same information as the chain of custody record with the addition of any field observations about the sample. The middle tube sample from the split spoon sampler or the soil from the sampler shoe will be placed in sealed glass containers. After approximately one half hour, a field reading will be taken using the H.N.U. 101 Photoionization Meter. The field readings will be recorded and used to determine the levels of fuel 7 e e contamination encountered in the testhole and alsò assist in selecting the soil samples to be analyzed in the laboratory. Soil samples will be delivered to B.C. Laboratories, Inc., a State Certified hazardous waste testing laboratory, within 24 hours after the sample is collected. The temperature will be maintained at 4 degrees Celsius in the insulated storage container prior to delivering to the laboratory. Once the samples are delivered to the laboratory, the chain of custody will be signed by the laboratory indicating that possession of the sampl es has changed. The soi 1 samp 1 es wi 11 be analyzed within the required 14-day period following collection, unless a 24 hour or 48 hour rush is required. Soils encountered at testhole borings will be logged and classified in accordance with the Unified Soil Classification System during drilling operations. Standard penetration blow counts will be recorded during soil sampling. The standard penetration test would consist of using a 140 pound drop hammer falling a distance of 30 inches to drive the sampler into the undisturbed soil and recording the number of blow counts required to drive the sampler each 6 inch increment. Personnel involved in collecting the soil samples and classifying the soi 1 s wi 11 be under the direct supervision of the proj ect engineer and fully experienced in the field of environmental and geotechnical drilling. 8 It It Lithologic descriptions to be included in the borehole log are: Soil type; color; moisture description; grain size and shape; compactness or hardness; cohesiveness; grading; extent of weathering or fracturing; and sample odor. Drilling rates, standard penetration tests, HNU P.I. Meter readings, sample numbers and percent recovery of the samples wi 11 al so by noted in the borehole field log. Testhole Boring Soil Containment and Abandonment During drilling operations, the soil cuttings will be placed on and covered with 4 mil. black plastic. The soi 1 cuttings wi 11 remain on-site in an area that is not accessible to the public. The soil cuttings will be labeled indicating the boring number and estimated depth of soil cuttings. After the augers are removed, the testho 1 e boreho 1 es wi 11 be backfilled with a 7-sack sand cement slurry. The soil cuttings will remain on-site until laboratory test results on soil samples are available. After review of the laboratory test results, appropriate disposal of the soil in each barrel can be determined. Our field investigation will be conducted in accordance with approved State of California LUFT Manual Recommendations, E.P.A. and Kern County Health Department Regulations and A.S.T.M. Test Methods. 9 e e , GRAB GROUND WATER SAMPLING PROCEDURES If it is determined that ground water has been impacted by gasoline, a grab sample will be collected through the hollow stem augers. A 1.7 x 3.0 acrylic bailer will be used to collect the sample. The augers will be raised approximately 5 feet to allow water to enter the borehole prior to collecting the water sample. The w~ter sample will be transferred into 2 sterilized glass, 40 mI. V.O.A. sample containers. The sample will be immediately sealed in the field insuring that no air bubbles occur after the container lid is placed over the sample containers. The samples will be labeled appropriately in the field. Labels will include: Sample location; depth; date; time; job number; and field identification number. Samples will be placed immediately in an insulated storage container containing blue ice. The temperature inside the storage container wi 11 be maintained at 4 degrees Ce 1 s ius /39.2 degrees Fahrenheit and monitored with a thermometer to insure that the temperature remains constant. The storage container wi 11 al so include a laboratory prepared travel blank to insure that cross contamination does not occur. The travel blank will be placed in with the sample containers and will be analyzed if the water samples indicate detectable levels of gasoline fuel constituents. A chain of custody record will accompany the samples. Chain of custody records will include: Sample location; depth; date; time; job number; field identification number; analysis required and ,n e e p~rsonnel collecting samples. A field log book will be maintained containing essentially the same information as the chain of custody record with the addition of any field observations about the sample. Water samples will be delivered to a state Certified hazardous waste testing laboratory wi thin 24 hours after the sample is co 11 ected. The temperature wi 11 be maintained at 4 degrees Celsiusj39.2 degrees Fahrenheit in the insulated storage container prior to delivery to the laboratory. Once the samples are delivered to the laboratory, the chain of custody will be signed by the laboratory indicating that possession of the samples has changed. The water samples will be analyzed with the required 7-day period following collection unless a 24 hour or 48 hour rush is required. 11 e e LABORATORY ANALYSIS: Soil and water samples collected from the testholes/ground water grab samples will be transferred to a State Certified Laboratory to perform the analysis required. Selected soil samples will be analyzed by B.C. Laboratories, Inc., of Bakersfield, CA.

Harris R.C.E. 15342, Exp. 3-31-93 13 e e REVISED HEALTH AND SAFETY PLAN FOR PENCE PETROLEUM COMPANY N.E. CORNER OF BEALE AVENUE AND EAST TRUXTUN BAKERSFIELD, CALIFORNIA GENERAL STATEMENT The site characterization for Pence Petroleum Company, 901 E. Truxtun, Bakersfield, California is being conducted to assess the vertical and latereal limits of on-site soil contamination. For preliminary assessment of contamination, three (3) testhole borings will be drilled. The soil sampling program will include soil cores, chemical analyses, grab samples, soil moisture measurements, and field screening by photoionization detector (PID). Detailed descriptions of borehole and drilling information will also be maintained. Decontamination procedures and health and safety measures conforming to Level D will be followed. Results from data analyses will be the basis of planning the subsequent investigation phase. 14 e e HAZARD EVALUATION This hazard evaluation is directed toward those volatile organic compounds which based on data gathered to date, are known or suspected to be present at sampling locations, they being: Benzene, Ethylbenzene, Toluene, Total Xylenes, Isopropylbenzene, Total Petroleum Hydrocarbons, Organic Lead, and Ethylene Dibromide. The U.S. Environmental Protection Agency (EPA) (1985) had defined levels of protection in order to provide a standard vocabulary to describe personal protection equipment. The four levels afford varying degrees of respiratory protection, dermal protection, and protection from traumatic injury. The four levels are summarized as follows: Level A consists of a totally encapsulated, chemically protective suit with self-contained breathing apparatus. Level B provides maximal respiratory protection through use of suppl ied air or sel f-contained breathing apparatus; the level of dermal protection is selected on the basis of anticipated hazards. Level C incorporates an air-purifying respirator which is specific to the contaminant(s) of concern; the degree of dermal protection depends on anticipated dermal hazards. Level D is basically a work uniform including hard hats, gloves and safety boots. 15 e e If the Safety Supervisor determines that hazardous or potentially hazardous conditions exist, they may require upgrading of the protection level from Level D to Level C. The Safety Supervisor also has the authority to stop all sampling-related work until adequate protection is provided for all workers, or until site hazards are mitigated. Safety equipment required for Level C includes air purifying respirators, chemical resistant clothing, gloves, boot covers, and hard hats. The Safety Supervisor may require the use of portable field monitoring equipment such as an organic vapor analyzer in order to determine whether respiratory protection is necessary. The following sections of the Health and Safety Plan describe safety equipment, decontamination procedures, and work limitations for sampling operations under Protection Level D. Emergency procedures in the event of personal exposure, injury, or explosion are also included for all operations, regardless of protection level. A separate section is provided describing Protection Level C safety equipment, decontamination procedures, personal precautions and site access. Protection Level C procedures will be followed if the Safety Supervisor determines that site hazards or potential site hazards warrant this level of protection. 16 e e SAFETY EQUIPMENT Safety equipment required for Protection Level D includes hard hats and boots. Hard hats will be worn during all drilling operations. Additional equipment available to the investigative team includes earplugs, disposable coveralls and boots, chemical-resistant gloves, and safety goggles. Use of this additional equipment shall be determined by the Safety Supervisor based on site conditions. EQUIPMENT The following equipment will be available for Protection Level D work: Protective Clothing AF-15 Pioneer nitrile gloves Tyvek coveralls, hoods, and boots Visual Uvex *9300 dust & chemical goggles Hearing Moldex pura-foam ear plugs Miscellaneous 16 unit first aid kit Barrier cream Hard hats~ ~ Hard hats are mandatory during all drilling operations. 17 e e DECONTAMINATION AND DISPOSAL Although the hazard evaluation indicated that harmful exposure to hazardous compounds in soils or groundwater is not likely to occur during the investigation, personnel decontamination accomplished by good personal hygiene practices should be followed to limit potential exposure to contaminants. Personnel decontamination is required prior to all breaks and meals, and at the end of the day. Decontamination of individuals will be accomplished by soap and water washing followed by a clean water rinse. When used, protective clothing, gloves, or goggles will be removed and stored in plastic bags prior to all breaks and meals. At the end of the day, disposable gloves, coveralls, and boots will be collected in plastic bags for disposal, and non-disposable protective equipment such as safety goggles will be decontaminated by soap and water washing followed by a clean water rinse. Procedures for disposal of investigation-derived materials have been established in accordance with federal and state hazardous waste regulations. Investigation-derived materials include soil cuttings and development water from monitor well drilling operations. If waste derived from investigation activities are determined by laboratory analysis to be hazardous, then disposal of those wastes will be conducted in compliance with EPA'g interim policy "Procedure for Planning and Implementing Off-site Response Actions" (Federal Register, 1985), as follows: 18 - e Treatment Treatment, reuse, or recycling of hazardous wastes will be considered in the removal of investigation-derived hazardous materials. Selection of Off-site Treatment or Disposal Facility Selection of an appropriate facility for off-site management of investigation-derived hazardous wastes will be based on the following requirements: 1. The owner or operator of any hazardous waste management facility under consideration must have a RCRA permit applicable to specific wastes and specific storage, treatment, or disposal processes. 2. A RCRA compliance inspection must be performed at the off-site facility to receive investigation-derived hazardous wastes not more than six months before receiving such wastes. 3. Any land disposal facility receiving investigation-derived hazardous wastes must meet RCRA minimum technical requirements per the Hazardous and Solid Waste Amendments of 1984. These technical requirements include ground water monitoring and liner and leachate collection system standards. 19 e Manifest Requirements e Investigation-derived hazardous material transported to an off-site storage, treatment, or disposal site will be accompanied by a Uniform Hazardous Waste Manifest, in compliance with requirements in the Code of Federal Regulations, 40 CFR 262. 20 e e PERSONAL PRECAUTIONS Eating, drinking, chewing gum or tobacco, smoking, or any practice that increases the probabi 1 i ty of hand-to-mouth transfer and ingestion of material should be avoided during drilling and soil sampling activities. Hands and face should be thoroughly washed upon leaving the work area. Contact with contaminated or suspected contaminated surfaces should be avoided. Whenever possible, do not walk through puddles, leachate, or discolored surfaces; kneel on ground; or lean, sit, or place equipment on drums, containers, or the ground. Medicine and alcohol can magnify the effects from exposure to toxic chemicals. Prescribed drugs should not be taken by personnel unless specifically approved by a qualified physician. 21 e e EMERGENCY PROCEDURES IN THE EVENT OF PERSONAL EXPOSURE Call the Safety Supervisor to the scene immediately. Immediately remove any clothing that becomes contaminated. Promptly wash with soap and flush with clean water. Determine the material involved.
