Jimerson c/o Mr. John Ivy San Joaquin Bank 4600 California Avenue Bakersfield, CA 93309 1;2 Area Map: See Exhibit 1 1.3 Site Map: See Exhibit 2 l ~4 Results of Tank Tests and Other Initial Site Work Completed: Two x 12,000 gallon diesel and two x 10,000 gallon gasoline underground storage tanks were removed from the site on October 30, 2000. Diesel contamination was found beneath the middle and west ends of the two diesel tanks. One x 3,000 gallon waste oil tank was removed on December 7, 2000. Previous work performed in February 1998, found diesel and gasoline contaminated soil and groundwater between the northeast dispensers that were removed in October 2000, and diesel and gasoline contaminated soil beneath the southwest dispensers that had been abandoned in 1985. There is also a reported 12,000 gallon underground diesel storage tank located south of the truck scale. A magnetic geophysical survey run in February 1998 was unable to locate the tank after auger drilling. The questionable anomaly was excavated to a depth of eight feet in December 2000 and no tank was found. 1.5 Quantity and Composition of Liquid Leaked: There is no estimate of the quantity of diesel or gasoline released since there are no records of product loss by inventory or tank test. The composition of liquid lost was determined by laboratory analysis of the soil samples from two feet and six feet beneath the removed diesel tanks and previous work performed in 1998. AJ Local TopoRraph¥. Geolo_ay~ Nearby Streams and Groundwater Depth - The site is almost level and is covered by blacktop, buildings, and concrete. It is graded to direct drainage to the three bordering streets. The immediate area has a very gentle grade to the north, controlled by the raised bed of Highway 99 that borders the west side of the property. The property lies in the outwash fan of the Kern River on Quaternary, recent Great Valley Fan Deposits. The soils are sandy with minor clays and silts. Nearby recharge sites are the: Calloway Canal - 1,200 feet northeast Pond - 2,700 feet north-northeast Kern River - 3,000 feet to the southeast Depth to groundwater: Approximately 30 feet below ground surface in the publication Improvement District No. 4, 1999 Report on Water Conditions, published by the Kern County Water Agency. A review of previous editions for the period from 1976 to 1999 showed that the water depth at this location has ranged from 15 feet beneath ground level in 1986 and 1987 to 100 feet in 1993. The gradient has been consistently to the west- northwest. 1.7 Date of Tank Removal and Condition of Tanks: The two diesel and two gasoline underground storage tanks were removed from the site on October 30, 2000. They were in excellent condition. There were no holes or corrosion and the protective coating was intact. The badly corroded waste oil tank was removed on December 7, 2000. 1.8 History of Tank Repair: ' There tank records available. are no repair 1.9 Tank Testin.q and Inventory Methods: No records of tank tightness testing or inventory control are on file. 1.10 Unauthorized Release Report Form: An Unauthorized Release Report Form was not found on file. AJ 1.,11 Solids or Liquid Wastes Removed: Sludge from the waste oil tank was shipped to Chemical Waste Management, Inc., Kettleman City, CA. Rinsate from the gasoline and diesel tanks was shipped to McKittrick Waste, Highway 58, McKittrick, CA. The manifests can be found in Appendix I. 1.12 History of Leaks~ Spills or Accidents on Site: There is no history of leaks, spills, or accidents on site. t.13 Previous Subsurface On-Site Work: Previous work performed in February 1998, found diesel and gasoline contaminated soil and groundwater between the northeast dispensers that were subsequently removed in October 2000, and diesel and gasoline contaminated soil beneath the southwest dispensers that had been abandoned in 1985. Groundwater was found at a depth of 17' 6" beneath the ground surface. There were no unusual problems encountered. A table listing the results of that work can be foUnd in Appendix II. 1998 The results of the soil sampling and groundwater test in 1998 are summarized below: Number of Borings: Twenty-nine borings were drilled, testing beneath existing underground tanks, existing dispensers, previously removed surface tanks, previously removed tanks and removed underground previously dispensers. Borings with Analysis: Samples from eighteen of the borings were analyzed because of elevated PID readings, hydrocarbon odor, staining, or because we felt it was the best procedure in spite of no traces of hydrocarbons. Borings without Analysis: Eleven borings had no samples analyzed because of no elevated PID readings, odor or staining. ! Number of Samples and Constituents Analyzed: 1 water sample was analyzed for BTEX, TPH-G, and TPH-D. 31 soil samples were analyzed for BTEX, TPH-G, and TPH-D. 1 soil sample was analyzed for lead, oil & grease, TOX substances.

October - December 2000 Lutrell Trucking removed the existing underground storage tanks, dispensers, and product lines. In the course of the investigation, evidence of diesel contamination was discovered beneath the west half of the two diesel tanks. Number of Sample Locations: Twenty locations were sampled testing the soil beneath, existing underground tanks, existing dispensers, and product lines. The excavation to locate and remove a reported diesel tank did not find a tank in the reported location. Samples with Analysis: All samples were analyzed. !

I 4.03 - ND mg/kg beneath west diesel dispenser D-3. The sample at 2' beneath the waste oil tank had 1,900 mg/kg TPH-Diesel and at 6' it was non detect. 1.14 History of Site and Tank Use The site has been a truck stop since 1947. Four underground tanks: 1 x 8,000 gallon diesel, 1 x 10,000 gallon diesel, and two x 8,000 gallon gasoline were removed in 1985 and the site received a closure letter from the Kern County Environmental Health Services Department. Two x 10,000 gasoline and two x 12,000 gallon diesel underground tanks were installed in 1985. These four tanks were removed on October 30, 2000. An approximately 3,000 gallon waste oil tank was removed in December 2000, as a result of being located by a magnetic geophysical survey. The same magnetic survey indicated a possible location for an underground 12,000-gallon diesel tank. Historic maps and diagrams were found that purported the location of the tank in the same area. Hand auger drilling and later backhoe excavation of the probable site found no tank present. 2,0 SOIL INVESTIGATION 2.1 Proposed Sampling Locations: Three soil S-2, & will be drilled to determine the borings (S-l, S-3) depth and areal extent of the plume associated with the two removed diesel tanks. This work will be performed upon receiving approval to commence from Bakersfield Fire Office of Environmental operations the Department Services. Borehole S-1 will be drilled at the location of the west sampling point of the south tank. Borehole S-2 will be drilled approximately 20 feet northwest of Borehole S-1 (Mapped Groundwater Gradient). Borehole S-3 will be drilled approximately ten feet southeast of Borehole S-1. Soil AJ samples will be taken in Borehole S-1 at two foot intervals starting at a depth of fifteen feet below the ground surface. Soil samples will be taken in Boreholes S-2 & S-3 will be sampled at five foot intervals to a depth of fifteen feet. Subsequent samples will be taken at two foot intervals. Sampling will stop when two HNU Portable Hydrocarbon Photo Ionization Detector (PID) readings above background are non-detect. In the event that contamination is found to ground water, S-1 will be developed as a permanent groundwater monitoring well. Three soil borings (S-4, S-5, & S-6) will be drilled to determine the depth and areal extent of the plume associated with the leaking gasoline and diesel dispensers that were abandoned in 1985. Borehole S-4 will be drilled adjacent to the dispenser. Borehole S-5 will be drilled approximately 10 feet southwest of Borehole S-4. Borehole S-6 will be drilled approximately 20 feet away from S-4 and to the same or greater depth. Soil samples will be taken in Boreholes S-4 & S-5 and S-6 at two foot intervals starting at a depth of four feet below the ground surface. Sampling will stop when two HNU Portable Hydrocarbon Photo Ionization Detector (PID) readings above background are non-detect. In the event that contamination is found to groundwater, the first of the holes that encounters it will be developed as a permanent groundwater monitoring well. An eight foot deep trench will be excavated south of the truck scale and scale house in an attempt to find the reported 12,000 gallon underground diesel tank. Soil samples (S-7 & S-8) will be taken at the base of the trench to determine if there is any contamination present, in the event that the reported 12,000 gallon underground diesel tank is not found. If the tank is found it will be removed. 2,2 Borinq Methodolo_~v: Drilling rig borings will be done using a truck mounted rig with eight and one half inch hollow - stem augers. After drilling to each sampling depth, sampling apparatus will be inserted into the hollow-stem auger and driven into the undisturbed soil beneath the borehole. A 2~" split spoon sampler fitted with three - 6" long brass sample tubes will be used to collect samples. The auger head will be cleaned prior to sampling, between sampling intervals, and between borings to minimize the possibility of cross contamination. Each boring will be logged by an A J Environmental, Inc., State of California Registered Geologist. 8 AJ 2.3 Sample Methodoloqy: All samples will be field checked for contamination using an HNU Portable Hydrocarbon Photo Ionization Detector (PID) prior to transporting them to the laboratory. The PID is an organic vapor analyzer that responds to hydrocarbons at very Iow concentration levels. It provides a continuous, direct readout of total organic vapor concentrations and does not respond to ambient gases such as carbon monoxide or carbon dioxide. Measurements are recorded in parts per million (ppm). It is also used as a screening tool to ensure the health and safety of field personnel. Prior to the collection of each soil sample, sample tubes will be washed with a non-phosphate detergent solution; triple rinsed with distilled water and air- dried. Immediately after sampling the tubes will be sealed with Teflon, capped with plastic end caps, sealed with duct tape, labeled and placed in a cooler containing ice and kept at a temperature of four degrees Celsius or less. Chain-of-Custody forms will be completed when the sample is collected and maintained with each transfer of the samples. The soil samples collected in the brass tubes will be capped, taped, labeled, and placed in cold storage of four degrees Celsius or less for transport to a State Certified Laboratory. A continuous soil description will be made of each boring. ,2,4 Laboratory Analysis: Selected samples will be analyzed by the laboratory for BTEXM (Benzene, Toluene, Ethyl-Benzene, Xylenes, MTBE), TPH-Gasoline and TPH-Diesel (Total Petroleum Hydrocarbons) (8020/8015) from Borings S-1, S-2, S-3, S-7 & S-8. 2.5 Soil Classification System All samples will be described using the Unified (ASTM) soil textural classification system. 2.6 Subcontractors Melton Drilling Company will perform the drilling operations. BC Laboratories, a state certified laboratory will perform the laboratory analysis. 2_.7 Soils Disposal and Borinq Destruction All contaminated soil not preserved for laboratory analysis will be placed in 55 gallon EPA approved drums that will be sealed, labeled, and temporarily AJ stored at the site. Upon receipt of laboratory analysis, the fate of the soil will be determined. All borings with contamination will be backfilled with bentonite pellets and cement. 2.8 Quality Assurance/Quality Control Procedures: This study has been undertaken to determine the horizontal and vertical extent of soil and groundwater contamination associated with the underground storage tanks and dispensers at Holden Truck Stop. Field procedures will follow the guidelines contained in the State Water Resources Control Board LUFT Field Manual dated October 18, 1989. The depth of each boring will be determined in the field by the project geologist. The locations of the drill holes will be determined by measurement from known facilities and elevations will be estimated from a topographic map. The locations and elevations should be considered accurate only to the degree implied by the method used. Drilling rig borings will be done using an eight and one half inch hollow-stem auger. After drilling to each sampling depth, sampling apparatus will be inserted into the hollow-stem auger and driven into the undisturbed soil beneath the borehole. A 2W' split spoon sampler fitted with three - 6" long brass sample tubes will be used to collect samples. The split spoon sampler will be cleaned prior to sampling, between sampling intervals, and between borings to minimize the possibility of cross contamination. Each boring will be logged by an A J Environmental, Inc., State of California Registered Geologist. Drill cuttings will be monitored for organic concentrations with an HNU meter. 3.0 GROUNDWATER INVESTIGATION The wells labeled GW-1 and GW-2 (Ground Water) will be drilled in the northwest and northeast corners of the property, sites not associated with known contaminated soils and will be developed as permanent groundwater wells. A third GW-3 will be drilled monitoring permanent monitoring well, into groundwater adjacent to the gasoline dispenser that showed evidence of leakage in the 1998 report. These wells will not only be used for soils and water testing but to establish a local groundwater gradient. Two temporary groundwater wells (GW 4 & 5) will be drilled ten and twenty feet away from GW-3 to establish a water level, test groundwater chemistry and determine the aereal extent of the plume. They will be sealed and abandoned after sampling. AJE 3.1 Nearby Groundwater Monitorinq Wells: Nearby Groundwater Monitoring Wells are shown in Exhibit 3. Kern County Water Improvement District 4 records show that the water gradient, to the west-northwest, has not changed since 1976. 3.2 Well Construction Dia,qram: See Exhibit 4 3.3 Drillin_cl Method and Decontamination between DrillinRs: All of the ground water monitoring wells will be drilled and completed by a truck mounted rig, using hollow - stem augers. All equipment used for the drilling, installation, development, and sampling will be decontaminated prior to use. All drilling equipment will be steam cleaned and air dried cleaned between holes. Prior to the collection of each soil sample, sample tubes will be washed with a non-phosphate detergent solution; triple rinsed with distilled water and air- dried. Immediately after sampling the tubes will be sealed with Teflon, capped with plastic end caps, sealed with duct tape, labeled and placed in a cooler containing ice and kept at a temperature of four degrees Celsius or less. Chain-of-Custody forms will be completed when the sample is collected and maintained with each transfer of the samples. The soil samples collected in the brass tubes will be capped, taped, labeled, and placed in cold storage of four degrees Celsius or less for transport to a State Certified Laboratory. A continuous soil description will be made of each boring. 3.4 Well Construction and Development: Each hole will be 8% inches in diameter. a. b. The casing will be 4" diameter, Schedule 40 PVC. The blank portion will extend from the surface to 10 feet below the ground surface. The 0.020 inch slotted portion will extend from 10 feet to fifty feet below the ground surface and be capped on bottom. c. The slotted liner will be surrounded with a #3 Monterey sand pack to a height of 18 to 24 inches above the slots. The liner will be placed so that the slots will be above and below the groundwater level in each well. The casing will be sealed for two feet with bentonite above the sand pack. The annulus will be filled with cement grout from the top of the bentonite seal to the surface. A locking well cap will be placed on top of the casing and a traffic box and cover will be installed around the well head. AJ d. The wells will be developed at least 24 hours after the grout has been installed. Water will be removed from the casings by air lift until the water is sediment free (three borehole volumes or the well blows dry). e. Contaminated soils encountered during drilling activities and contaminated water from well development operations will be placed in 55 gallon drums and stored on-site pending receipt of laboratory analysis. They will then be properly disposed of. f. A licensed land surveyor will survey all of the wells. A mark will be placed on the north side of each casing and be surveyed with an accuracy of 0.01 feet. They will also be surveyed in relation to existing benchmarks at the site. This data will be used to prepare a site map and calculate the groundwater flow direction and gradient. 3.5 Water Samplin.q After the groundwater levels have stabilized from development activities, water samples will be collected. They will be collected using disposable polyethylene bailers. The samples will be transferred to sample bottles provided by the laboratory. They will be labeled with the date, time, location, and sampler's name. After labeling, the samples will be placed in a chilled ice chest for delivery to a California Certified laboratory. Water levels and free product levels (if present) will be measured using an electric tape. Each well will be purged by removing three casing volumes and then measured and sampled when the original (static) water level has recovered. Wells will be sampled on a quarterly basis and the gradient will be determined each time. All samples will be analyzed for TPH- Diesel, TPH-Gasoline, and BTEXM. 3.6 Quality Assurance/Quality Control Quality Assurance/Quality Control will be attained during sampling activities by utilization of a travel blank. This blank will be unopened and will be submitted to the laboratory with the other samples. Chain-of- Custody forms will be completed when the sample is collected and maintained with each transfer of the samples.
