Systems Environmental (ESE) .has been contracted by Kern Environmental Service (KES) representing Don Keith Transportation to prepare this report for the completion of the remediation activities which have been undertaken at the Don Keith's Asphalt and Diesel Transportation Company located at 2990 Pierce Road, Bakersfield, California (Figure 1). Don Keith Transportation 2 January 29, 1993 0 These activities include the excavation and bioremediation of approximately 4,500 cubic-yards of soils impacted with petroleum hydrocarbon compounds associated with three earthen elarifiers connected to a truck wash rack as well as excavation and use as dust control cover of approximately 2,500 cubic yards of an asphaltic petroleum hydrocarbon .impacted soil associated with the former operation of three tanker truck bottoms disposal pits which were documented by ESE in the above referenced reports. 1.0 EXECUTIVE SUMMARY Excavation at the site began on September 8, 1992 and initially concentrated on the two tanker truck bottoms disposal pits in the rear of the property (Figure 2). During excavation an additional pit was discovered. Due to this discovery, and the Kern County Resources Management Agency - Department of Environmental Health Services' (KCDEHS) request that the excavation be conducted to a depth of 20 feet below surface grade, the volume of soil excavated was increased to approximately 3,000 cubic yards over an area 100 feet north to south and 50 feet east to west. Laboratory analysis has verified no detectable concentrations beyond these limits. The excavation pit has subsequently been backfilled with import material, compacted to greater than 90% maximum density, and returned to surface grade. Approximately 1,500 cubic yards of the excavated material consists of asphaltic residue mixed with sandy soil. Similar material has been previously stockpiled on site which was determined by the Regional Water Quality Control Board - Central Valley Region to be suitable for use as a dust control material for the property. The KCDEHS has concurred that the newly excavated material is of a similar nature and is therefore also suitable for dust control following the same proscribed criteria of an application not to exceed three inches in thickness. The other 1,000 cubic yards were a low level petroleum hydrocarbon impacted silty sand material which has been successfully bioremediated on site. Bioremediation continued until the concentrations of total extractable petroleum hydrocarbons as diesel were less than 100 rog/kg. ESE recommends that the treated soil be used as grading fiIl material on site. -' EB-8228-3 9301-$030.RPT Don Keith Transportation 3 January 29, 1993 0 Upon completion of the excavation of the tank bottoms pits, focUs shifted to the wash water earthen elarifiers in the center of the property (Figure 2). Excavation preceded to the dimensions contained in the original work plan of 75 feet east to west by 40 feet north to south for a volume of petroleum hydrocarbons impacted sandy and silty sand soil of approximatelY 2,250 cubic yards. Soil sampling verified clean sidewalls for the clarifier excavation with the exception of the northeast corner of the excavation. In this location a 12 inch diameter pipe was observed leading to the northeast, and surrounded by a halo of petroleum impacted soil. Excavation was initiated on September 18, 1992 to expand the pit in this direction. It was soon discovered that a third chamber to the clarifier system was present to the north and east of the original two chamber clarifier (Figure 2). Excavation has continued in this area through September 22, 1992 to establish the dimensions of this third chamber. The third chamber appears to have been very similar in size to the original excavation, and also involves approximately 2,250 cubic yards of slightly impacted soil. Soil sampling has been conducted which verified clean sidewalls for the third clarifier excavation. The excavation pit has subsequently been backfilled with import material, compacted to greater than 90% maximum density, and returned to surface grade. The 4,500 cubic yards of petroleum hydrocarbon impacted soil from the three chambers has been bioremediated on site. Bioremediation continued until~ the concentrations of total extractable petroleum hydrocarbons as diesel were less than 100 mg/kg. ESE recommends that the treated soil be used as grading fill material on site. The soil undergoing bioremediated was placed as a one foot layer on the property. Treatment of the soil consisted of enhancing indigenous soil microbes through the oxygenation effects of mechanical cultivation, and accelerated through nutrient conditioning which consisted of the one time addition of a' time released nitrogen/phosphorous additive to establish a weight ratio of carbon:106, nitrogen:16, and phosphorous:l which has been shown to yield optimum biodegradation rates in similar petroleum hydrocarbon impacted soil. Application was in dry form using a spreader and tilling into the soil. This was followed by moisture conditioning using a water truck, and a second round of tilling. -- EB.8228.3 9301-5030.RPT Don Keith Transportation 4 January 29, 1993 Progress of the treatment cell has been monitored through field screening as well as periodic sampling of the soil and analysis for the presence of TEPH as diesel, and TRPH as oil and grease. The analytical results indicated that the treatment has been progressively successful in reducing the concentration of the diesel hydrocarbons. On January 8, 1993, ESE collected nine soil samples from the treatment cells, and analyzed these samples for petroleum hydrocarbons using a fuel fingerprint. The results of the analysis were non detected .for TEPH as diesel. However, heavier molecular weight hydrocarbons identified as crude oil remain to a maximum concentration of 2,000 mg/kg. The ehromatograms for each of the samples as well as an example of Kern County diesel and crude oil chromatograms are provided with the laboratory reports in Appendix A. They demonstrate how definitively the identification of the remaining petroleum hydrocarbons is crude oil, and not diesel. Therefore, the remaining hydrocarbons in the treated soil are similar to the material which was previously stockpiled on site and determined by the Regional Water Quality Control Board - Central Valley Region to be suitable for use as a dust control material for the property. ESE recommends that the soil be removed from the treatment cell, and spread as grading fill on the property, and that ~the site be considered by KCDEHS for closure. All methods employed by ESE for this remediation are in compliance with regulations and guidelines set forth in California Code of Regulations (CCR) Title 22, Article 11, and Title 23, Chapter 3, California Site Mitigation Decision Tree Manual, the Code of Federal Regulations (CFR) Title 29, Part 1910, Section 120, CFR Title 40, Parts 300-399, and San Joaquin Valley Unified Air Pollution Control District, Kern County Zone Rule 463.5, as well as accepted professional environmental/geoteehnieal engineering procedures and applicable local regulations. - - EB-8228-3' 9301-5030.RPT Don Keith Transportation 5 Janua~ 29, 1993 2.0 SITE BACKGROUND 2.1 Site Description The site is located at 2990 Pierce Road in the city of Bakersfield in Kern County,' California (Figure 1). The site is currently used as a parking area where the tanker trucks are parked. The site is situated within a developed industrial area. Nearby surrounding properties are primarily retail businesses, petroleum service companies, refineries, and actual oil producing properties. The overall site topography is essentially flat, with a very slight fall to the west. 2.2 Project History Based on conversations with Chris DeArmon at Kern Environmental Services (KES), two locations on the subject property had a potential for subsurface soil impacted with petroleum hydrocarbons and required assessment as part of a baseline environmental assessment at Don Keith's Asphalt and Diesel Transportation Company. The first area is that of a very large, two stage, earthen bottom clarifier system which formerly served the truck wash for the crude oil, asphalt, fuel oil and diesel fuel trucking firm. The clarifiers have been backfilled and no surface evidence remains. The property owner has provided a description of the size of each clarifier, and flagged their boundaries. The second area consists of two disposal pits in the rear of the property which received tanker truck bottoms. The surface of these has been covered with soil, however stained soil is visible at the surface in the location of the two pits. ESE has conducted an initial site characterization consisting of eleven soil borings and laboratory analysis of 27 soil samples to evaluate the extent of petroleum hydrocarbons impacted soil in the vicinity of both the former truck wash earthen elarifiers and tank bottom disposal pits. --- EB-8228-3 9301-5030.RPT Don Keith Transportation 6 January 29, 1993 0 2.2.1 Subsurface Investigation Drilling of four initial borings was conducted on July 13, 1992. Drilling of seven additional .borings to more fully assess the vertical and lateral extent of the impacted soils was conducted on August 6, 1992. A total of eleven soil borings were drilled within this phase of soil characterization (Figure 2). One soil boring, TH-1 was drilled on July 13, 1992 through the center of the western of the two former truck wash cIarifiers location to a depth of 31 feet below surface grade to assess the potential for petroleum hydrocarbons in the subsurface at that location. On August 6, 1992 this boring was twinned by boring TH-lA which was advanced to a depth of 46 feet to assess the vertical limit of the petroleum hydrocarbons encountered in boring TH-1. A soil boring, TH-2 was drilled on July 13, 1992 through the center of the eastern of the two former clarifiers to a depth of 36 feet below surface grade to assess the potential for petroleum hydrocarbons at that location. On August 6, 1992 this boring was twinned by boring TH~2A which was advanced to a depth of 48.5 feet to assess the vertical limit of the petroleum hydrocarbons encountered in boring TH-2. Soil borings TH-3A, TH-4 and TH-4A were advanced around the periphery of the two earthen clarifiers to assess the lateral limits of the petroleum hydrocarbons encountered in borings TH-1 and TH-2. Soil boring TH-3A was drilled drilled-35 feet southeast of TH-2 outside of the former eastern clarifier location to a depth of 29 feet to assess the the potential for lateral migration of petroleum hydrocarbons in that direction. Soil boring TH-4 was drilled drilled 20 feet north of TH-2 to a depth of 26 feet to assess the the potential for lateral migration of petroleum hydrocarbons in that direction. Soil boring TH-4A was drilled drilled 35 feet southwest of TH-I to a depth of 35 feet to assess the the potential for lateral migration of petroleum hydrocarbons in that direction. - ~' EB -8228-3 9301-5030.RPT Don Keith Transportation ? 1anuary 29, 1993 0 A soil boring, NP was drilled through the center of the northern tank bottom disposal pit location to a depth of 27 feet below surface grade to assess vertical migration of petroleum hydrocarbons at that location. Soil boring TH-3 was drilled drilled 25 feet northeast of NP to a depth of 31 feet to assess the the potential for lateral migration of petroleum hydrocarbons in that direction. A soil boring, SP was drilled through the center of the southern tank bottom disposal pit location to a depth of 36 feet below surface grade to assess vertical migration of petroleUm hydrocarbons at that loeati_on. Soil boring SPL was drilled drilled 35 feet east of SP to a depth of 21 feet to assess the the potential for lateral migration of petroleum hydrocarbons in that direction. To better define the limits of the two tank bottoms disposal pits a backhoe operated by Kern Environmental Service was used to excavate five foot deep trenches in the rear portion of the .property. Upon exposing the limits of the pits a composite soil sample was collected from the sludge within the two pits at a depth of three feet below surface grade. S0il Investigation Laboratory. Analysis Twenty-six soil samples and one sludge sample were submitted to B. C. Laboratories of Bakersfield, California for analysis. All twenty-seven samples were analyzed for Total Recoverable Petroleum Hydrocarbons (TRPH) as oil and grease using USEPA Test Method 418.1. Seven of the samples including the tank bottoms sludge were analyzed for California Title 22 metals. Six of the samples including four from the area of the earthen clarifiers, and two from the 'area of the tank bottoms disposal pits were analyzed for volatile and semi-volatile organics using USEPA Test Methods 8240 and 8270. Five samples _including the' sludge were analyzed for Total Extractable Petroleum Hydrocarbons as diesel (TEPHd) using the DOHS LUFT Manual Method. Four deeper soil samples beneath the earthen clarifiers were analyzed for total lead using the DOHS'LUFT Manual Method. The tank bottom pit sludge was also analyzed for fuel constituent volatile aromatics using USEPA Test Method 8020, and for pH. ~' EB-8228-3 9301-$030.RPT Don Keith Transportation 8 January 29, 1993 2.'2.2 Res~llts of the Investigation Geologic Setting Regional Geology: The site is located in the southern part of the Great Valley geomorphic province. The Great Valley is a north-south trending valley, approximately 400 miles long by 50 miles wide. Surface and groundwater in the San Joaquin Valley is derived predominantly from the Sierra Nevada mountain range to the east, and is transported by five major rivers, the southern most being the Kern River. The subject site is located approximately 1/2 mile northwest of the Kern River. The surface of the San Joaquin Valley is composed primarily of unconsolidated Pleistocene (1.6 million to 11,000 years ago) and Recent (11,000 years ago to the present) alluvial sediments. Beneath the alluvial sediments are older, predominantly lake bed deposits. These lie unconformably on Mio-Pliocene marine sediments which extend to crystalline basement at approximately 20,000 feet. Site Geology: Geologic deposits in the study area include Pleistocene alluvial sediments of the Kern River Formation, which form 'a homocline dipping gently to the west. The deposits are alluvium consisting of poorly indurated and dissected fan deposits (CDMG,1964). The depth to the regional unconfined aquifer was estimated prior to drilling to be approximaiely 50 feet below surface grade beneath the site (Kern County Water Agency, Improvement District No. 4, 1991 Report on Water Conditions, February 1992). Groundwater was not encountered in boring TH-2A which penetrated to a depth of 48.5 feet. The deepest samples in the borings were moist, but did not have an indication that the capillary fringe to groundwater was at that depth. Because of the six consecutive years of drought, and the discontinuance by the Kern County Water Agency of using several large water recharge percolation ponds 1/2 mile to the north, a drop in the elevation of groundwater by as much as 25 feet may have occurred in the area. - - EB -8228-3 9301-5030.RPT Don Keith Transportation 9 January 29, 1993 O The nearest known occurrence of perched groundwater is eight miles to the southeast at a depth of 20 feet in the abandoned Kern River channel to the ancient Kern Lake Bed (Kern County Water Agency, 1991 Water Supply Report, May 1992). No perched groundwater is known to exist beneath the subject site. Subsurface material encountered during drilling was alluvium to the total depth of each boring. The alluvium was characterized by unconsolidated, highly permeable, light brown, silty sand (SM) to a depth of approximately 7 feet, overlying unconsolidated, highly permeable, tan, well graded fine- to coarse- grained sand (SW) to a depth of approximately 23 feet. This is underlain by a sequence of unconsolidated, highly permeable, light tan, fine- to coarse- grained gravelly sand (SW/GW) to a depth of 38 feet. Beneath this is a sequence of unconsolidated, highly permeable, light tan, fine- to coarse- grained sand (SW) to a depth of 43, overlying unconsolidated, highly permeable, light tan, well graded fine- to coarse- grained moderately silty sand (SW/SM) to a depth of approximately 46 feet. This is underlain by a sequence of consolidated, moderate to Iow permeability, light tan, very clayey silt (ML/CL) to a depth of 48.5 which was the greatest depth investigated. Laboratory. Analytical Results - Soil Investigation Total Recoverable Petroleum Hydrocarbons (TRPH) as oil and grease were detected at a concentration of 7,900 mg/kg at 10 feet in boring TH-1 advanced through the center of the western clarifier location, but not at 20, 30, 40 and 45 feet in boring TH-lA advanced in the same location. TRPH was detected at a concentration of 10,000 mg/kg at 10 feet in boring TH-2 advanced through the center of the eastern clarifier location and 40 mg/kg at 20 feet in boring TH-2A, but not at 40 and 47 feet in boring TH-2A. TRPH was not detected at depths of 15 and 25 feet in boring TH-3A advanced 35 feet southeast of TH-2 on the outside of the former clarifier location, or at depths of 10 and 20 feet in boring TH-4 advanced 20 feet north of TH-2, or at depths of 10 and 25 feet in boring TH-4A advanced 35 feet southwest of TH-1. However, TRPH was detected at 20 mg/kg at a depth of 35 feet in boring TH-4A. Total Extractable Petroleum Hydrocarbons as diesel (TEPHd) were analyzed for in the soil samples at 20 feet in borings TH-IA and TH-2A at concentrations of 19 mg/kg, and 23 rog/kg, respectively. -' EB-8228-3 9301-5030.RPT Don Keith Transportation 10 January 29, 1993 O The fuel constituent volatile aromatics m- and p-xylenes were detected at a concentration of 0.006 mg/kg at 10 feet in boring TH-1. The fuel constituent volatile aromatics toluene was detected at a concentration of 0.022 rog/kg at 10 feet in boring TH-2. No other~ volatile organic hydrocarbons including those which constitute fuels and industrial solvents were detected at or above the minimum detection limit in the four soil samples collected from the clarifier area. No semi-volatile organic hydrocarbons (base neutral and acid extractables) were detected at or above the minimum detection limit in the four soil samples collected from the elarifier area. Lead was detected at an elevated concentration in one of eight samples from the clarifier area. Total lead was detected at a concentration of 27 mglkg at a depth of 10 feet in boring TH-2 advanced through the center of the eastern clarifier, but was not detected in boring TH-2A at 20 and 40 feet, at 10 and 20 feet in boring TI-I-4 position 20 feet north of TH-2, and at I0 feet in boring TH-1 or 20 feet in boring TH-lA both located in the center of the western elarifier. Total lead was detected at 2.7 rog/kg at 20 feet in boring TH-lA. The State of California Title 22 Total Threshold Limit Concentration (TTLC) for lead is 1,000 mg/kg. However, the Soluble Threshold Limit Concentration (STLC) for soluble lead is 5 rog/kg. Because of the 10:1 dilution that occurs during the wet extraction any total concentration less than 50 mg/kg will necessarily be-determined to have a soluble component less than the STLC of 5 rog/kg. Therefore, a soluble lead wet extract was not performed on the sample in this investigation with a concentration of total lead detected of 27 rog/kg. Arsenic, barium, chromium, cobalt, copper, nickel, vanadium, and zinc were detected in the four soil samples from the clarifier area at concentrations typical of the background concentrations for these metals in the soil in the area of the subject property. The other Title 22 metals were not detected in the four soil samples from the clarifier area. EB-8228-3 9301-5030.RPT Don Keith Transportation 1 1 ~anuary 29, 1993 0 Total Recoverable Petroleum Hydrocarbons (TRPH) as oil and grease was detected at a concentration of 45,000 mg/kg is the composite sample of the sludge from at depth of three, feet within the tank bottoms disposal pits. Total Extractable Petroleum Hydrocarbons as diesel (TEPHd) was detected at a concentration of 12,000 rog/kg in this sample. The fuel constituent volatile aromatics benzene, toluene, ethylbenzene, and total xylenes were detected at concentrations of 0.013 mg/kg, 0.038 mg/kg, 0.021 rog/kg, and 0.177 mg/kg, respectively. The pH of the sludge was measured at 7.17. TRPH was not detected in the north pit vertical assessing boring NP at depths of 10, 20 and 25 feet, and in the north pit lateral boring TH-3 at 15 and 25 feet. TRPH was detected in the south pit vertical assessing boring SP at I0 feet at a concentration of 20 mg/kg and 25 feet at a concentration of 60 mg/kg and in the south pit lateral boring SPL at 10 feet at a concentration of 160 mg/kg, but not in vertical assessing boring SP at a depth of 35 feet, or in the south pit lateral boring SPL at 20 feet. The semi-volatile organic hydrocarbon diethyl phthalate was detected at a concentration of 0.1 rog/kg at 15 feet in boring TH-3 advanced adjacent to the northern tank bottoms disposal pit. No other volatile organic hydrocarbons, or semi- volatile organic hydrocarbons were detected at or above the minimum detection limit in the two samples collected from the area of the tank bottoms disposal pits. Lead was detected at an elevated concentration in the sample of the sludge from the disposal pits. Total lead was detected at a concentration of 44 rog/kg. The State of California Title 22 TTLC for lead is 1,000 rog/kg. However, the STLC for soluble lead is 5 mg/kg. Because of the 10:1 dilution that occurs during the wet extraction any total concentration less than 50 rog/kg will necessarily be determined to have a soluble component tess than the STLC of 5 rog/kg. Therefore, a soluble lead wet extract was not performed on the sludge sample. "' EB-8228-3 9301-5030.RPT Don Keith Transportation 12 January 29, 1993 0 Cadmium was detected at 1.2 mg/kg in the sludge. Cadmium's TTLC is 100 rog/kg, and STLC is I mg/kg. Copper was detected at 66 rog/kg in the sludge. Copper's TTLC is 2,500 rog/kg, and STLC is 25 mg/kg. Mercury was detected at 0.39 rog/kg in the sludge. Mercury's TTLC is 20 me/kg, and STLC is 0.2 rog/kg. Nickel was detected at 61 mg/kg in the sludge. Nickel's TTLC is 2,000 rog/kg, and STLC is 20 mg/kg. Vanadium was detected at 87 mg/kg in the sludge.' Vanadium's TTLC is 2,400 mg/kg, and STLC is 24 rog/kg. Each of these concentrations are far below their respective regulatory limits. Therefore, the sludge is not classified as a hazardous material by RCRA and California Title 22 criteria. However, these concentrations are in excess of that which occurs in the native soil and indicates an accumulation from the petroleum products. There may be a minor amount of mobility for these metals from the sludge into the underlying soil, however this has not been observed in the investigation. The Regional Water Quality Control Board provides recommended guidelines for TRPH as oil and grease, TEPH as diesel, the fuel constituent volatile aromatics, benzene, toluene, ethylbenzene and total xylenes, and the semi-volatile organic hydrocarbon diethyl phthalate using the LUFT methodology by multiplying the most stringent current federal or state water quality standards by a factor of 100 to account for attenuation due to site-specific parameters including vertical separation to ground water, soil lithology, fractures in subsurfaces, annual average precipitation, and any direct conduits to groundwater. These recommended guidelines are 1,000 rog/kg for TRPH as oil and grease, 100 rog/kg for TEPH as diesel, 0.3 rog/kg for benzene, 1.0 rog/kg for toluene, 4.0 mg/kg for ethylbenzene, 3.0 rog/kg for total xylenes, and 50 mg/kg for diethyl phthalate. Laboratory analytical results for the twenty seven soil samples from the eleven soil borings are summarized in Table I. - - EB-8228-3 9301-5030.RPT Don Keith TransportatiOn. 13 January 29, 1993 O TABLE-I SUMMARY OF LABORATORY ANALYTICAL DATA values in milli Der kilo ..

TTLC: State of California Title 22 Total Threshold Limit Concentration- EB-8228-3 9301-5030.RPT Don Keith Transportation 1 4 January 29, 1993 2.2.3 Conclusions of the Subsurface Investigation The data obtained suggest that soil impacted beneath the former location of the truck wash earthen clarifiers has been impacted by petroleum hydrOcarbons at concentrations in excess RWQCB recommended guidelines to a depth of less than 20 feet below surface. The data does not indicate that fuel constituents, solvents, or heavy metals have impacted this soil. ESE concludes that the petroleum hydrocarbons detected represent heavier molecular weight crude oil and refined products devoid of known hazardous constituents. The lateral extent of this impacted soil does not extend laterally from the boundaries of the' former clarifiers. Therefore, ESE estimates that the soil between the base of the former clarifiers at a depth of 8 feet to a depth of 18 feet has concentrations of TRPH as oil in grease in excess of the recommended guidelines over an area 75 feet long by 40 feet wide for a volume of impacted soil of approximately 1,000 cubic yards. It was ESE's opinion that excavation of the soil to these dimensions would remove all of the impacted soil with concentrations of TRPH as oil and grease in excess of 100 mg/kg. The operation of the tank bottoms disposal pits appears to have impacted the soil to a depth of less than 10 feet at the location of the pits. The data does not indicate that fuel constituents, solvents, or heavy have impacted this soil. However, the sludge does contain slightly elevated concentrations of heavy metals, but remains classified as non-hazardous by RCRA'and California Title 22 criteria. ESE concludes that the petroleum hydrocarbons detected represent heavier molecular weight crude oil and refined products. The lateral extent of this impacted soil'does not extend laterally from the boundaries of the disposal pits. Therefore, ESE estimates that the soil within the northern pit to a depth of 10 feet has concentrations of TRPH as oil in grease in excess of the recommended guidelines over an area 30 feet long by 25 feet wide for a volume of impacted soil of approximately 140 cubic yards, and soil within the southern pit to a depth of 10 feet over an area 55 feet long by 15 feet wide for a volume of approximately 150 cubic yards. It was ESE's opinion that excavation of the soil to these dimensions would remove all of the impacted soil with concentrations of TRPH as oil and grease in excess of 100 rog/kg. EB-8228-3 9301-$030.RPT Don Koith Transpomttion 15 January 29, 1993 O 2.2.4 R¢commendatio.ns from. th~ Sllbsurface Investigation ESE recommended excavation and surface bioremediation of the soil beneath the former elarifiers, and excavation and use as dust inhibitor of the crude oil and asphalt sludge from the disposal pits. ESE recommended that the impacted soil from beneath the former clarifiers be excavated to a depth 18 feet and treating the soil to concentrations less than the RWQCB recommended guidelines through the process of bioremediation at the subject property. Surface bioremediation has been shown to be particularly successful in the San Joaquin Valley given the high temperature, and low relative humidity. This option was particularly viable at this site since the facility has available land to treat the soil. The impacted soil beneath the former clarifiers responded very well to surface bioremediation. Because the property is in a commercial/petroleum setting, there was only a slight risk of exposure of any off site population to volatilized petroleum hydrocarbons, and therefore very little health risk to the general public associated with the treatment. This option was particularly attractive since on site treatment alleviates the clients future liability for the soil. ESE recommended that the impacted soil from beneath the former disposal pits should be excavated to a depth of I0 feet where the site assessment indicates that the limits of concentrations in excess of the RWQCB recommended guidelines were reached. The soil would then be used as a dust inhibitor at the subject property. -- EB-8228-3 9301-5030.RPT Don Keith Transportation 16 January 29, 1993' 2.2.5 Soi! Excavation Kern Environmental Services provided front end loaders, and an excavator to remove the estimated 2,500 cubic yards of impacted soil and asphaltic sludge from the three tank bottoms disposal pit in the rear of the property, and 4,500 cubic yards of petroleum impacted soil from the three truck wash earthen elarifiers in the eemral portion of the property (Figure 2).' Excavation was conducted on the days of September 8 through September 21, 1992. Prior to excavation, Underground Service' Alert (USA) was notified 48 hours in advance. In addition, the excavation contractor obtained necessary excavation permits from California Occupational Safety and Health Administration (Cai OSHA). Petroleum impacted soils in the areas identified by the ESE Site Assessment Study dated August 12, 1992 were removed by eXcavating with from end loaders, and an excavator. The impacted soil was segregated into two stockpiles. One stockpile consisted of 1,500 cubic yards of soil and asphaltic sludge from the tank bottoms disposal pits. This material was thoroughly mixed with the solid asphaltic material pulverized using a Bomag Reclaimer so that no fragment 'exceeds 2 1/2 inches in diameter. This material will be applied for dust control to the rear two thirds of the property at a thickness not to exceed three inches (Figure 2). The second stockpile consists of 5,500 cubic yards of petroleum impacted soil generated from the peripheral edges of the tank bottoms disposal pits and the truck wash earthen clarifiers. This material was placed within a remediation cell covering the rear two thirds of the property using a rubber tire from end loader. Excavating proceeded at the location of the tank bottoms disposal pits to a depth of 20 feet below surface grade over an area 100 feet north to south and 50 feet east to west (Figure 2). Excavating proceeded at the location of the truck wash earthen elarifiers to a depth of 20 feet below surface grade over an area 75 feet east to west by 40 feet -- EB-8228-3 9301-5030.RPT Don Keith Transportation 17 Sanuary 29, 1993 north to south at the two southwestern clarifiers, and to a depth of 23 feet below surface grade over an area 75 feet east to west by 40 feet north to south at the northeastern clarifier (Figure 2). The excavation was performed so that sidewall slopes conformed to California and Federal OSHA code requirements. Excavation Pit .Field Screening During excavation soil samples were collected from the base and sidewalls of the excavation'pit and were visually screened, for the presence of petroleum' hydrocarbons. Excavation was continued until there was no evidence in the sidewalls and pit base of stained soils, or soils containing petroleum odors. Integration of the final dimensions of the excavated pit with data collected from the previous site characterization at the property indicated that no concentrations of TEPH as diesel or TRPH as oil and grease in excess of 100 mg/kg should be remaining in the subsurface. Confirmation soil samples have been collected under the direction of a KCDEHS representative from the boundaries of the excavations to verify satisfactory removal of the impacted soil. Soil S~mple Collection Six verification soil samples were collected from the base and sidewalls of the tank bottoms excavation 'pit at the locations shown on Figure 3. One soil sample was collected from each of the four sidewalls at a depth of 10 feet below surface grade, and two soil samples were collected from the base of the excavation. Ten verification soil samples were collected from the base and sidewalls of the southwestern truck wash earthen elarifier excavation pit at the locations shown on Figure 4. Two soil samples were collected from each of the four sidewalls at a depth of 10 feet below surface grade, and two soil samples were collected from the base of the excavation. EB-8228-3 9301-5030.RPT Don Keith Transportation 18 January 29, 1993 O Five verification soil samples were collected from the base and sidewalls of the northeastern truck wash earthen clarifier excavation pit at the locations shown on Figure 4. One soil sample was collected from each of the three sidewalls (no south sidewall is present due to adjacent clarifier excavation) at a depth of 10 feet below surface grade, and two soil samples were collected from the base of the excavation. Undisturbed soil samples were obtained by driving a modified Shelby Tube sampler containing stainless steel sleeves with a weighted sliding hammer. The soil samples were immediately sealed with Teflon® liners, capped, labeled, and placed on ice for transport to a California Department of Health Services (DOHS) certified laboratory. Strict chain of custody procedures were utilized for all samples collected to ensure sample integrity and to document sample possession from the time of collection to the final destination. Laboratory Analysis: Excavation Verifigati0n $oil Samples The soil samples were analyzed at BC Laboratories, a State of California certified laboratory for total recoverable petroleum hydrocarbons, as oil and grease using USEPA Test Method 418.1. Analytical Results - Excavation .Pits All of the six soil samples from the tank bottoms excavation were non detected for TRPH as oil and grease. Five of the soil samples from the southwestern track wash earthen clarifiers were non detected for TRPH as oil and grease. One of the samples detected TRPH as oil and grease at a concentration of 40 mg/kg. The samples from the northeastern portion of the excavation detected TRPH as oil and grease at a concentrations of 3,400 mg/kg, and 700 rog/kg. This corner was subsequently excavated when the northeastern clarifier was removed. Four of the five soil samples collected from the northeastern truck wash clarifier excavation were non detected for TRPH as oil and grease. One of the soil samples from the northeastern clarifier detected TRPH as oil and grease at a concentration of 20 rog/kg. --- EB-8228-3 ·. 9301-5030.RPT Don Keith Transportation 19 January 29, 1993 0 Table 2 presents a summary of the analytical results for TRPH as oil and grease from the base and sidewalls of the excavation pits: TABLE 2.

EB-8228-3 9301-5030.RPT Don Keith Transportation 20 January 29, 1993 0 Backfill and Compaction Upon review of the laboratory results,' and with the approval of the KCDEHS, the excavation pits resulting from soil removal were baekfilled from September 22 through October 8, 1992 with "clean" import soil to replace the removed impacted soil. The soil was compacted to 90% relative compaction in 12 inch lifts under the direction of an on-site soils engineer. Compaction tests were performed at one foot intervals from the base of the excavation to surface grade. Backfilling was accomplished using an 815 mechanical compacter, a 966 loader, and a water truck. A report was prepared by the Earth Systems' civil engineering division which certifies that the excavation was backfilled in such a way that the compaction exceeds 90%. This report was included as in ESE's "Report of Remedial Action", dated October 20, 1992. 3.0 BIOREMEDIATION DESIGN, MANAGEMENT, AND MONITORING The 5,500 cubic yards of petroleum impacted soil excavated from the site was placed as a one foot thick lift over the rear two thirds of the property. The bioremedial system utilized active mechanical cultivation by a tractor and plow combination on a biweekly basis. A significant decrease in the concentration of the petroleum hydrocarbons through aeration, and oxygenation was expected through the mechanical cultivation of petroleum hydrocarbons with the molecular weight of diesel. A recommended treatment guideline for TEPH as diesel of 100 rog/kg was established in conjunction with the KCDEHS. ESE recommended that the bioremediation process be accelerated through nutrient conditioning. This consisted of a one time application of a time released nitrogen/phosphorous additive to establish a weight ratio of carbon:106, nitrogen:16, and phosphorous:l which has been shown to yield optimum biodegradation rates in similar petroleum hydrocarbon impacted soil. On December 1, 1992, KES applied one pound of N:16/P:I nutrients per cubic yard of impacted soil. Application was in dry form using a spreader and tilling into the soil. This was followed by moisture conditioning using a water truck, and a second round of tilling. -" EB-8228-3 9301-5030.RPT Don Keith Transportation 21 January 29, 1993 The remaining 1,500 cubic yards of asphaltic residuals from the tank bottoms pits was thoroughly mixed with the solid asphaltic material pulverized using a Bomag Reclaimer so that no fragment exceeds 2 1/2 inches in diameter. This material has been stockpiled at the rear of the facility and will be applied for dust control to the rear two thirds of the property at a thickness not to exceed three inches. 4.0 PROGRESS SOIL SAMPLING The progress of the treatment has been monitored-periodically by field screening for visual signs of soil discoloration, staining, and diesel odors. Two soil samples were collected on September 23, 1992 from the initial bench scale treatment area west and southwest of the clarifier excavation' pit during the period when the excavation process was ongoing (Figure 5). Two soil samples were collected on October I, 1992 from the bench scale area to determine is aggressive daily mechanical cultivation had a significant effect on the bioremedial process (Figure 6). Upon completion of the backfilling of the excavation pits, all of the stoekpiled~soil was spread out over the rear two thirds of the property. On October 23, 1992, nine soil samples were collected from the entire treatment area after three weeks of weekly mechanical cultivation (Figure 7). After completing five additional weeks of treatment nine samples were collected on December 1, 1992, prior to the application of the nutrient additive (Figure 8). Mechanical cultivation and moisture conditioning continued for six additional weeks on a biweekly basis. On January 8, 1993, nine soil samples were again collected from the entire treatment area (Figure 9). For each sampling event, undisturbed soil samples were obtained by driving a modified Shelby Tube. sampler containing stainless steel sleeves with a weighted sliding hammer, immediately sealed with Teflon® liners capped, labeled, and placed on ice for transport to a California Department of Health Services (DOHS) certified laboratory. Strict chain of custody procedures were utilized for all samples collected to ensure sample integrity and to document sample possession from the time of collection to the final destination.

The nine January 8, 1993 soil samples were analyzed at BC Laboratories for a fuel fingerprint of the petroleum hydrocarbons by USEPA Test Method 8015 (modified for fuel fingerprint). The analytical reports for January 8, 1993 as well as the individual chromatograms and sample chromatograms for Kern County diesel and crude oil are included as Appendix E. 6.0 ANALYTICAL RESULTS - TREATED SOIL In the September 23, 1992 sampling event, TRPH as oil and grease was detected in one soil sample at 1,700 rog/kg while TEPH as diesel was detected at 1,100 mg/kg. In the second sample, TRPH as oil and grease was 380 rog/kg while TEPH as diesel was 200 mg/kg. Therefore, diesel hydrocarbons appeared to represent 60% of the total petroleum hydrocarbons. -' ' EB-8228-3 9301-5030.RPT Don Keith Transportation 23 January 29, 1993 0 In the October 1, 1992 sampling event, TRPH as oil and grease were detected in similar locations at 1,900 mg/kg and 500 mg/kg. This appeared to indicate that daily cultivation for one week had not significantly reduced the concentrations of total petroleum hydrocarbons. In the October 23, 1992 sampling event, TEPI-I as diesel was detected at concentrations ranging from 100 rog/kg to 1,200 rog/kg in the nine soil samples. This appeared to indicate that slow progress was being made toward reducing the concentration of petroleum hydrocarbons, but that a more aggressive treatment regime including nutrient and moisture conditioning was warranted. Prior to conducting the nutrient application, nine samples were collected on December 1, 1992 and detected TEPH as diesel from 400 mg/kg to 1,000 mg/kg. The confirmed slow progress, and supported the decision to proceed with more aggressive treatment. It should be noted that an internal consistency is present in the proceeding four sampling events. Areas of the treatment cell which were initially observed to have higher concentrations are consistently higher throughout the four sampling events (i.e. the southwest corner had TEPI-I as diesel at 1,100 rog/kg on September 23, 1992, TRPH as oil and grease at 1,900 mg/kg on October 1, 1992, TEPH as diesel at 1,100 rog/kg on October 23, 1992, and TEPH as diesel at 1,000 mg/kg on December 1, 1992). The same consistency is present in areas of the treatment cell which were initially observed to have lower concentrations and are consistently lower throughout the four sampling events (i.e. the southwest extension had TEPH as diesel at 200 rog/kg on September 23, 1992, TRPH as oil and grease at 500 rog/kg on October 1, 1992, TEPH as diesel at 400 mg/kg on October 23, 1992, and TEPH as diesel at 300 rog/kg on December 1, 1992). This consistent pattern indicates that a sampling frequency has been established which provides representative and repeatable results. EB-8228-3 9301-5030.RPT Don Keith Transportation 24 January 29, 1993 O Following six weeks of moisture conditioning after the single application of nutrients, it was decided that a more sophisticated analytical methodology was warranted. Field screening no longer indicated that lighter molecular weight hydrocarbons were present. Odors had diminished to being virtually imperceptible. No discoloration or staining of the soil could be observed. Therefore, the nine January $, 1993 samples were analyzed for a fuel fingerprint. The results confirmed our field observations. TEPH as diesel was not detected in any of the nine samples. What is detected are heavier molecular weight hydrocarbons which range /'rom 1,300 rog/kg to 2,000 rog/kg. Their chromatograms virtually overlay that of Kern County crude oil. A diesel chromatogram is a bell shaped curve with retention times ranging from 11 to 22 minutes, and dominated by hydrocarbons with retention times from 13 to 18 minutes. The chromatogams of the nine samples were virtually non detected at less than 15 minutes, extended to over 26 minutes, and had a dominant peak at 21 minutes. The determination that diesel hydrocarbons are not present is particularly strong in the interval from 11 to 15 minutes where diesel would have risen to its peak, but no hydrocarbons are detected during these retention times in the nine samples. Even more striking are the similarities of all nine chromatograms to each other, and to a typical Kern County crude oil. The base of the chromatogram have a similar slope. The chromatograms have two peaks, one at 17.3 minutes and the second at 21.4 minutes. The tails of the chromatograms from 21.4 to 26 minutes have similar concave shapes. The bulk of the hydrocarbons are observed between 16 and 23 minutes. There is a distinctive trough centered at approximately 20.5 minutes. Stuart Buttram who supervises the organic chemistry department at B C Laboratories states that the petroleum hydrocarbons detected in the nine samples are crude oil, and as such the presentation format of the fuel fingerprint laboratory reports are designed to provide a signed certification of this interpretation.

No additional soil mitigation is deemed to be necessary in these locations. The bioremediation of the impacted soil through mechanical cultivation and nutrient conditioning, has reduced the concentration of diesel hydrocarbons in the soil to less than the RWQCB recommended guideline of 100 rog/kg. The remaining hydrocarbons in the treated soil are similar to the material which was previously stockpiled on site and determined by the Regional Water Quality Control Board Central Valley Region to be suitable for use as a dust control material for the property. -' EB-8228-3 9301-5030.RPT Don Keith Transportation 27 January 29, 1993 8.0 RECOMMENDATIONS ESE recommends that the soil be removed from the treatment cell, and spread as grading fill on the property, and that the KCDEHS considered the site for closure. 9.0 CLOSURE This report has been prepared for the exclusive use of KES, HEI, and Don Keith Transportation as it pertains to the location of the former truck wash earthen clarifiers, and tank bottoms disposal pits at 2990 Pierce Road, Bakersfield, California. The results contained in each verbal or written report are based upon the information acquired during the assessment. It is possible that variations could exist beyond points explored during the course of the investigation. Also, changes in conditions found could occur at some time in the future due to contaminant migration, variations in rainfall, temperature, and/or other factors not apparent at the time of the field investigation. This report should not be regarded as a guarantee that no further contamination, beyond that which may have been detected within the scope of this study, is present on or beneath the site. If additional information regarding the possible presence or past use of hazardous materials at the site becomes available, then the need for further field investigation should be re-evaluated. Similarly, ·if suspected contamination is encountered during earthwork or construction activities, a qualified engineer or geologist should be on-site to monitor the soils and collect samples for laboratory analysis. The services performed by ESE were conducted in a manner consistent with the level of care and skill ordinarily exercised by members of our profession currently practicing under similar conditions in the state of California. No other warranty is expressed or implied. .... EB-8228-3 9301-5030.RPT Don Keith Transportation 28 January 29, 1993 O Thank you for this opportunity to be of service.

These activities include the excavation and bioremediation approximately 4,500 cubic-yards of soils impacted with petroleum hydrocarbon compounds associated with three earthen clarifiers connected to a truck wash rack as well as excavation and use as dust control cover of approximately 2,500 cubic yards of an asphaltic petroleum hydrocarbon impacted soil associated with the former operation of three tanker truck bottoms disposal pits recently documented by ESE in the above referenced report. Don Kieth Transportation 2 October 20, 1992 1.0 Introduction Excavation at the site began on September 8, 1992 and initially concentrated on the two tanker truck bottoms disposal pits in the rear of the property (Figure 2). During excavation an additional pit was discovered. Due to this discovery, and the Kern County Resources Management Agency - Department of Environmental health Services' (KCDEHS) request that the excavation be conducted to a depth of 20 feet below surface grade, the volume of soil excavated was increased to approximately 3,000 cubic yards over an area 100 feet north to south and 50 feet east to~ west. Laboratory analysis has verified no detectable concentrations beyond these limits (see Appendix A). The excavation pit has subsequently been backfilled with import material, compacted to greater than 90% maximum density, and returned to surface grade. Approximately 1,500 cubic yards of the excavated material consists of asphaltic residue mixed with sandy soil. Similar material has been previously stockpiled on site which was determined by the Regional Water Quality Control Board Central Valley Region to be suitable for use as a dust control material for the property. The KCDEHS has concurred that the newly excavated material is of a similar nature and is therefore also suitable tbr dust control following the same proscribed criteria of an application not to exceed three inches in thickness. The other 1,000 cubic yards is a low level petroleum hydrocarbon impacted silty sand material which is being successfully bioremediated on site. Bioremediation will continue until the concentrations are less than 100 rog/kg for total extractable petroleum hydrocarbons as diesel. The treated soil will then be used as grading fill material on site. Upon completion of the excavation of the tank bottoms pits, focus shifted to the wash water earthen clarifiers in the center of the property (Figure 2). Excavation preceded to the dimensions contained in the original work plan of 75 feet east to west by 40 feet north to south for a volume of petroleum hydrocarbons, impacted sandy EB-8228-3 9210-E015.RPT Don Kieth Transportation 3 October 20, 1992 and silty sand soil of approximately 2,250 cubic yards. Soil sampling verified clean sidewalls for the clarifier excavation with the exception of the northeast comer of the excavation (see Appendix B). In this location a 12 inch diameter pipe was observed leading to the northeast, and surrounded by a halo of petroleum impacted soil. Excavation was initiated on September 18, 1992 to expand the pit in this direction. It was soon discovered that a third chamber to the clarifier system was present to the north and east of the original two chamber clarifier (Figure 2). Excavation has continued in this area through September 22, 1992 to establish the dimensions of this third chamber. The third chamber appears to have been very similar in size to the original excavation, and also involves approximately 2,250 cubic yards of slightly impacted soil. Soil sampling has been conducted which verified clean sidewalls for the third clarifier excavation (see Appendix B). The excavation pit has subsequently been backfilled with import material, compacted to greater than 90% maximum density, and returned to surface grade. The 4,500 cubic yards of petroleum hydrocarbon impacted soil from the three chambers is being bioremediated on site. Bioremediation will continue until the concentrations are less than 100 mg/kg for total extractable petroleum hydrocarbons as diesel. The treated soil will then be used as grading fill material on site. The soil undergoing bioremediated has been placed as a one foot layer on the property. Treatment of the soil has consisted of enhancing indigenous soil microbes through the oxygenation effects of mechanical cultivation. Three soil samples have been collected from treatment cell and analyzed for the presence of TEPH as diesel, and TRPH as oil and grease. The analytical results indicate that the mechanical cultivation has been moderately successful in reducing the concentration of these petroleum hydrocarbons. /~ESE is currently r~ecommending that this process be accelerated through nutrient conditioning. This will consist of the addition of a time released nitrogen/phosphorous application to establish a weight ratio of carbon: 106, nitrogen: 16, and phosphorous:l which has been shown to yield optimum EB-8228-3 9210-E015.RPT Don Kieth Transportation 4 October 20, 1992 biodegradation rates in similar petroleum hydrocarbon impacted soil. The carbon weight is based on the concentration of hydrocarbons in the soil. ESE recommends the application of two pounds of N:16/P:I nutrients per cubic yard of impacted soil. Application will be in dry form using a spreader and tilling into the soil. This will be followed by moisture conditioning using, a water truck, and a second round of tilling. ds that the treatm_eenl in _the form of mechanical cultivation and periodic_g~mniqure cnm~g using a water truck should then continue for a period of two to three months. During this time frame samples will be collected from the treatment celI'"T6 monitor the progress of reducing TEPH as diesel to below 100 mg/kg_~ When the concentrations have been reduced to below this recommended guideline, con~firmation sampl~ing will be conducted in the presence of the KCDEHS representative. ESE recommends that a grid be established so that a sample is collected for each 50 cubic yards of impacted soil and that these samples then be composited in the laboratory at a 4:1 ratio and analyzed for the presence of TEPH as diesel. This will result in an estimated 25 samples for laboratory analysis. Upon verification of successful treatment, ESE will recommend that the soil be removed from the treatment cell, and spread as grading fill on the property. ESE will subsequently recommend that the site be considered for closure. All methods employed by ESE for this remediation are in compliance with regulations and guidelines set forth in California Code of Regulations (CCR) Title 22, Article 11, and Title 23, Chapter 3, California Site Mitigation Decision Tree Manual, the Code of Federal Regulations (CFR) Title 29, Part 1910, Section 120, CFR Title 40, Parts 300-399, and San Joaquin Valley Unified Air Pollution Control District, Kern County Zone Rule 463.5, as well as accepted professional environmental/geotechnical engineering procedures and applicable local regulations. EB-8228-3 9210-E015.RPT Don Kieth Transportation 5 October 20, 1992 The work plan employed by ESE to date to excavate and treat the petroleum impacted soils has included: · Preparation of a site Health and Safety Plan in accordance with regulations set forth in Federal OSHA CFR 29 1910.120, as well as California OSHA regulations. · Excavation of approximately 4,500 cubic yards of impacted soil beneath the location of the former truck wash clarifiers. · Excavation of approximately 2,500 cubic yards of soil and sludge materials within the former tanker truck bottoms disposal pits. · Confirmatory sampling and analysis of the excavation pit bases and sidewalls. · Backfilling the pits with "clean" import fill material, compacting, and returning to surface grade. · Stockpiling the tank bottoms soil and sludge on site for later application as a three inch dust control cover. · Placement of the clarifier impacted soil in a twelve inch lift over the rear portion of the property. · Mechanical cultivation increasing oxygenation and enhancing indigenous soil microbes to reduce the concentrations of the petroleum hydrocarbons to beneath RWQCB recommended guidelines. · Progress monitoring and sampling. · Preparation of this report documenting ongoing remediation activities. 2.0 Health & Safety Plan A written Health and Safety plan was implemented for site work conducted during the mitigation phase of this project. The purpose of the plan was to provide specific safety procedures to be implemented during the handling of petroleum hydrocarbon contaminated materials. The Health and Safety Plan was required under regulations set forth in Federal OSHA CFR 29 1910.120, since the referenced reports documented the presence of potentially hazardous materials at the site. EB-8228-3 9210-E015.RPT Don Kieth Transportation 6 October 20, 1992 3.0 Soil EXcavation Kern Environmental Services provided front end loaders, and an excavator to remove the estimated 2,500 cubic yards of impacted soil and asphaltic sludge from the three tank bottoms disposal pit 'in the rear of the property, and 4,500 cubic yards of petroleum impacted soil from the three truck wash earthen clarifiers in the central portion of the property (Figure 2). Excavation was conducted on the days of September 8 through September 21, 1992. Prior to excavation, Underground Service Alert (USA) was notified 48 hours in advance.' In addition, the excavation contractor obtained necessary excavation permits from California Occupational Safety and Health. Administration (Cai OSHA). Petroleum impacted soils in the areas identified by the ESE Site Assessment Study dated August 12, 1992 were removed by excavating with front end loaders, and an excavator. The impacted soil has been segregated into' two stockpiles. One stockpile consists of 1,500 cubic yards of soil and asphaltic sludge from the tank bottoms disposal pits. This material has been thoroughly mixed with the solid asphaltic material pulverized using a Bomag Reclaimer so that no fragment exceeds 2 1/2 inches in diameter. This material will eventually be applied for dust control to the rear two thirds of the property at a thickness not to exceed three inches (Figure 2). The second stockpile consists of 5,500 cubic yards of petroleum impacted soil generated from the peripheral edges of the tank bottoms disposal pits and the truck wash earthen clarifiers. This material has been placed within a remediation cell covering the rear two thirds of the property using a rubber tire front end loader. Excavating proceeded at the location of~qL__f___f___f___~tank bottoms disposal pits~..~ ,~opth of '2_0 '"'feet beiow surface grade over an are..a. 100 feet north to south and 50 feet east to.._.~st (Figure 2). Excavating proceeded at the location of the truck wash earthen clarifiers to a depth of 20 feet below surface grade over an area 75 feet east to west by '40 feet ' ' EB -8228-3 9210-E015.RPT Don Kieth Transportation 7 October 20, 1992 O north to south at the two southwestern clarifiers, and to a depth of 23 feet below surface grade over an area 75 feet east to west by 40 feet north to south at the northeastern clarifier (Figure 2). The excavation was performed so that sidewall slopes conformed to California and Federal OSHA code requirements. 4.0 Excavation Pit Field Screenine During excavation soil samples were collected from the base and sidewalls of the excavation pit and were visually screened for the presence of petroleum hydrocarbons. Excavation was continued until there was no evidence in the sidewalls and pit base of stained soils, or soils containing petroleum odors. Integration of the final dimensions of the excavated pit with data collected from the previous site characterization at the property indicated that no concentrations of TEPH as diesel or TRPH as oil and grease in excess of 100 mg/kg should be remaining in the subsurface. Confirmation soil samples have been collected under the direction of a KCDEHS representative from the boundaries of the excavations to verify satisfactory removal of the impacted soil. 5.0 Soil Sample Collection Six verification soil samples were collected from the base and sidewalls of the tank bottoms excavation pit at the locations shown on Figure 3. One soil sample was collected from each of. the four sidewalls at a depth of I0 feet below surface grade, and two soil samples were collected from the base of the excavation. Ten verification soil samples were collected from the base and sidewalls of the southwestern truck wash earthen clarifier excavation pit at the locations shown on Figure 4. Two soil samples were collected from each of the four sidewalls at a depth of 10 feet below surface grade, and two soil samples were collected from the base of the excavation. EB-8228-3 9210-E015.RPT Don Kieth Transportation 8 October 20, 1992 Five verification soil samples were collected from the base and sidewalls of the northeastern truck wash earthen clarifier excavation .pit at the locations shown on Figure 4. One soil sample was collected from each of the three sidewalls (no south sidewall is present due to adjacent clarifier excavation) at a depth of 10 feet below surface grade, and two soil samples were collected from the base of the excavation. Undisturbed soil samples were obtained by driving a modified Shelby Tube sampler containing stainless steel sleeves with a weighted sliding hammer. The soil samples were immediately sealed with Teflon® liners, capped, labeled, and placed on ice for transport to a California Department of Health Services (DOHS) certified laboratory. Strict chain of custody procedures were utilized for all samples collected to ensure sample integrity .and to document sample possession from the time of collection to the final destination. 6.0 Laboratory Analysis: Excavation Verification Soil Samples The soil samples were analyzed at BC Laboratories, a State of California certified laboratory for total recoverable petroleum hydrocarbons as oil and grease using USEPA Test Method 418.1. The analytical reports for the tank bottoms excavation are included as Appendix A, the southwestern truck wash clarifiers as Appendix B, and the northeastern truck wash clarifier as Appendix C. 7.0 Analytical Results - Excavation Pits All of the six soil samples from the tank bottoms excavation were non detected for TRPH as oil and grease. Five of the soil samples from the southwestern truck wash earthen clarifiers were non detected for TRPH as oil and grease. One of the samples detected TRPH as .oil and grease at a concentration of 40 mg/kg. The samples from the northeastern portion of the excavation detected TRPH as oil and grease at a concentrations of 3,400 mg/kg, and 700 mg/kg. This corner was subsequently excavated when the northeastern clarifier was removed. Four of the five soil samples collected from the northeastern truck wash clarifier excavation were non detected for TRPH as oil and grease. One of 'the soil samples from the northeastern clarifier detected TRPH as oil and grease at a concentration of 20 mg/kg.

Note: The soil in excess of the RWQCB recommended guidelines indicated in the samples from the eastern and northeastern sidewalls of the southwestern clarifiers (8287-8 & 9) was removed with the excavation of the northeastern clarifier. --- EB-8228-3 9210-E015.RPT Don Kieth Transportation 1 0 October 20, 1992 8.0 Backfill and Compaction Upon review of the laboratory results, and with the approval of the KCDEHS, the excavation pits resulting from soil removal was backfilled from September 22 '. through October 8, 1992 with "clean" import soil to replace the removed impacted soil. The soil was compacted to 90% relative compaction in 12 inch lifts under the direction of an on-site so'ils engineer. Compaction tests were performed at one foot intervals from the base of the excavation to surface grade. Backfilling was accomplished using an 815 mechanical compacter, a 966 loader, and a water truck. A report was prepared by the Earth Systems' civil engineering division which certifies that the excavation was backfilled in such a way that the compaction exceeds 90%. This report is included as Appendix D, and provides the compaction test reports as documentation. 9.0 Bioremediation Design, Management, and Monitorine The 5,500 cubic yards of petroleum impacted soil excavated from the site was placed as a one foot thick lift over the rear two thirds of the property. The bioremedial system utilizes active mechanical cultivation by a tractor and plow combination On a___a da~ily ~ A significant decrease in the concentration of the petroleum hydrocarbons through aeration, and oxygenation can be expected through the mechanical cultivation of petroleum hydrocarbons with the molecular weight of diesel. However, the heavier molecular weight asphaltic hydrocarbons will not achieve significant decreases without aggressive enhancement of the biological degradation process. A recommended treatment guideline of 100 mg/kg has been established in conjunction with the KCDEI-IS. It is ESE's opinion that to obtain these cleanup concentrations without nutrient conditioning to enhance the biological processes will require a time frame in excess of four months. Upon completion of the treatment, receipt of confirmation laboratory analysis, and the approval of KCDEI-IS, the treated soil will be used as grading fill on the property. EB-8228-3 9210-E015.RPT Don Kieth Transportation 1 1 October 20, 1992 The remaining 1,500 cubic yards of asphaltic residuals from the tank bottoms pits has been thoroughly mixed with the solid asphaltic material pulverized using a Bomag Reclaimer so that no fragment exceeds 2 1/2 inches in diameter. This material has been stockpiled at the rear of the facility and will eventually be applied for dust control to the rear two thirds of the property at a thickness not to exceed three inches. 10.0 Progress Soil Sampling The progress of the treatment has been monitored periodically by field screening for visual signs of staining, and diesel odors. Five composite soil samples have been collected from locations within the treatment cell, each representing a portion Of the soil which has been exposed to mechanical cultivation for a different time interval. Undisturbed soil samples were obtained by driving a modified Shelby Tube sampler containing stainless steel sleeves with a weighted Sliding hammer, immediately sealed with Teflon® liners capped, labeled, and placed on ice for transport to a California Department of Health Services (DOHS) certified laboratory. Strict chain of custody procedures were utilized for all samples collected to ensure sample integrity and to document sample possession from the time . of collection to the final destination. I 1.0 Laboratory Analysis of Treated Soil The five soil samples were analyzed at BC Laboratories, a State of California certified laboratory for total recoverable petroleum hydrocarbons as oil and grease by USEPA Test Method 418.1. Three of the soil samples have also been analyzed for the presence of total extractable petroleum hydrocarbons as diesel by USEPA Test Method 8015 (modified for diesel). The analytical reports are included as Appendix E. EB - $228-3 9210-E015.RPT Don Kieth Transportation 1 2 October 20, 1992~ 12.0 Analytical Results Treated Soil // All five of the soil samples detected the presence of TRPH as oil and grease, and the three samples analyzed for TEPH as diesel detected those hydrocarbons. TRPH as oil and grease was detected at a concentration of 1,900 mg/kg in the soil which has been treated the shortest durationl and decreased to 380 mg/kg in the soil which has been treated the longest duration. TEPH as diesel was detected at a concentration of 2,000 mg/kg in the soil which has been treated the shortest duration, and decreased to 200 mg/kg in the soil which has been treated the longest duration.

No additional soil mitigation is deemed to be necessary in these locations. The bioremediation of the impacted soil through mechanical cultivation enhancing oxygenation has reduced the concentration of diesel hydrocarbons in the soil. 14.0 Recommendations ESE recommends that the bioremediation process be accelerated through nutrient conditioning. ~his will consist of the addition a time released nitrogen/phosphorous application .to establish a weight ratio of carbon:106, nitrogen:16, and phosphorous:l which has been shown to yield optimum biodegradation rates in similar petroleum hydrocarbon impacted soil. The carbon weight is based on the concentration of hydrocarbons in the soil. ESE recommends the application of two pounds of N:16/P:I nutrients per cubic yard of impacted soil. Application will be in dry form using a spreader and tilling into the soil. This will be followed by moisture conditioning using a water truck, and a second round of tilling. ESE recommends that the treatment in the form of mechanical cultivation and periodic moisture conditioning using a water truck should then continue for a pe~riod of two to three months. During this time frame samples will be collected from the treatment cell to monitor the progress of reducing TEPH as diesel to below 100 mg/kg. When the concentrations have been reduced to below this recommended guideline, confirmation sampling will be conducted in the presence of the KCDEI-IS representative. ESE recommends that a grid be established so that a sample is collected for each 50 cubic yards of impacted soil and that these samples then be composited in the laboratory at a 4:1 ratio and analyzed for the presence of TEPH as diesel. This will result in an estimated 25 samples for laboratory analysis. Upon verification of successful treatment, ESE will recommend that the soil be removed from the treatment cell, and spread as grading fill on the property. EB-8228-3 9210-E015.RPT Don Kieth Transportation 1 4 October 20, 1992 O The remaining 1,500 cubic yards of asphaltic residuals from the tank bottoms pits has been thoroughly mixed with the solid asphaltic material pulverized using a Bomag Reclaimer so that no fragment exceeds 2 1/2 inches in diameter. This material has been stockpiled at the rear of the facility and will eventually be applied for dust control to the rear two thirds of the' property at a thickness not to exceed three inches. ESE will subsequently recommend that the site be considered for closure. 15.0 Closure This report has been prepared for the exclusive use of KES, HEI, and Don Keith Transportation as it pertains to the location of the former truck wash earthen clarifiers, and tank bottoms disposal pits at 2990 Pierce Road, Bakersfield, California. The results contained in each verbal or written report are based upo.n the information acquired during the assessment. It is possible that variations could exist beyond points explored during the course of the investigation. Also, changes in conditions found could occur at some time in the future due to contaminant migration, variations in rainfall, temperature, and/or other factors not apparent at the time of the field investigation. This report should not be regarded as a guarantee that no further contamination, beyond that which may have been detected within the scope of this study, is present on or beneath the site. If additional information regarding the possible presence or past use of hazardous materials at the site becomes available, then the need for further field investigation should be re- evaluated. Similarly, if suspected contamination is encountered during earthwork or construction activities, a. qualified engineer or geologist should' be on-site to monitor the soils and collect samples for laboratory analysis. The services performed by ESE were conducted in a manner consistent with the level of care and skill ordinarily exercised by members of our profession currently practicing under similar conditions in the state of California. No other warranty is expressed or implied. EB-8228-3 92 lO-E015.RPT Don Kieth Transportation 15 October 20, 1992 Thank you for this opportunity to be of service.

O. Box 5337 Bakersfield, CA 93388 Project: Don Keith Trucking Subject: Report of Observation and Testing During Excavation Backfill Submitted herewith is the final report of testing and continuous observations performed during the backfill at the above referenced project. Backfill operations were performed by Kern Environmental Service using conventional heavy equipment Testing was performed per the authorization of Chris DeArmon, KP-q Operation Supervisor. Test results and locations are presented on the attached test report summary sheets. Compaction tests were performed in accordance with ASTM D 2922-81 and ASTM D 3017-88, Nuclear Der~ty Test Method. The maximum density and optimum moistures were determined in the laboratory in accordance with ASTM D 1557-78, Method A. Tes~ results are as follows: Soil Description USC~ Maximum Density-Optimum Moisture Tan slightly clayey, SC 124.0 11.0 (not used) silty medium to coarse sand. Tan slightly silty sand SM 123.0 9.5 Light tan clean fine sand 111.0 $.0 Discussion: 1. The scope of our work was to test the compaction of the backfill material being placed in the previously excavated oily sump areas. 2. The project is located at 2990 Pierce Road, Bakersfield, California. Kern Environmental Service Job No. S-20430-B01 ~r20,1992 3.. The proposed use of the site will be for parking area. 4. Areas to receive f'dl Were processed by scarification, moisture conditioning and recompaction. 5. Soils previously removed from the excavated areas were not used in the backfill operation. 6. Fill materials consisting of import soils were placed in thin layers and compacted into place. 7. Fill materials were compacted using conventional heavy equipment. 8. Areas not achieving minimum density requirements were reworked and retested until the desired densities were obtained. 9. Fill placed on slopes were keyed and benched into firm natural ground. The keyways were banked into the slope. 10. A total of sixty-four (64) density tests were performed. 11. Test results indicate that a minimum of ninety (90) percent of maximum dry density has been obtained in the areas tested. 12. Locations and elevations of in-situ tests were determined in accordance with their importance and accuracy and proximity of provided survey control. Unless otherwise noted, their locations and elevations were determined by pacing and visual sighting. 13. Based upon continuous observations and testing during the backfill operations from September 28 1992 through October 7, 1992 on this project, it is our opinion that the job requirements have been met. 14. We make no warranty expressed or implied, except that our services were performed in accordance with engineering principles generally accepted at this time and location. 15. As used herein, the term "observation" applies only that we observed the progress of work we agreed to be involved with, and performed tests on which we based our opinion as to whether the work essentially complies with the job requirements. 16. With any manufactured product, there are statistical variations in its uniformity, and in the accuracy of tests used to measure its qualities. As compared with other manufactured products, field construction usually has wider fluctuations in both product and test results. Thus, even with very careful observation and testing, it cannot be said that all parts of the product EARTH SYSTEMS CONSULTANTS Kern Environmental Service Job No. S-20430-B01 Octo~r 20,1992 comply with the job requirements. Therefore, our opinion, based on observing and testing the work, means only that we performed our services in such a manner as tn have reasonable certainty that the work essentially complies with the job requirements. If there are any questions concern/ng this report, please do not hes/tate to contact this office. Respectfully submitted, EARTH ~ SOUTHERN CAT.TI~DRNIA APPROVED: · Pdchard M.

ESE had originally proposed to excavate and bioremediate approximately 1,000 cubic-yards of soils impacted with petroleum hydrocarbon compounds associated with two earthen elarifiers connected to a truck wash rack as well as excavating and disposing of approximately 300 cubic yards of an asphaltic petroleum hydrocarbon sludge associated with the former operation of two tanker truck bottoms disposal pits recently documented by ESE in the above referenced report. Upon initiating excavation activities, the volumes of impacted soils were determined to be in excess of the original estimates. Therefore, ESE is proposing modifications to the original work plan which are described in Section 3 of this document. Don Keith Transportation 2 September 22, 1992 2.0 PROJECT PROGRESS REPORT Excavation at the site began .on September 8, 1992 and initially concentrated on the two tanker truck bottoms disposal pits in the rear of the property (Figure 2). During excavation an additional pit was discovered. Due to this discovery, and the Kern County Resources Management Agency Department of Environmental health Services' (KCDEHS) request that the excavation be conducted to a depth of 20 feet below surface grade, the volume of soil excavated was increased to approximately 3,000 cubic yards over an area 100 feet north to south and 50 feet east to west. Laboratory analysis has verified no detectable concentrations beyond these limits (see Appendix A). Approximately 1,500 cubic yards of the excavated material consists of asphaltic residue mixed with sandy soil. Similar material has been previously stockpiled on site which was determined by the Regional Water Quality Control Board Central Valley Region to be suitable for use as a dust control material for the property. The KCDEHS has concurred that the newly excavated material is of a similar nature and is therefore also suitable for dust control following the same proscribed criteria of an application not to exceed three inches in' thickness./ The other 1,500 cubic yards is a low level petroleum hydrocarbon impacted silty sand material which is being successfully bioremediated on site. Bioremediation will continue until the concentrations are less than 100 mg/kg for petroleum hydrocarbons. The treate__~d~s, oi~L_wili then--be.-used as backfill material on site. ~ I Upon completion of the excavation of the tank bottoms pits, focus shifted to the wash water earthen clarifiers in the center of the property (Figure 2). Excavation preceded to the dimensions contained in the original work plan of 75 feet east to west by 40 feet north to South for a volume of moderately petroleum hydrocarbons impacted sandy soil of approximately 1,000 cubic yards, and 1,250 cubic yards of slightly petroleum hydrocarbons impacted sandy and silty sand soil. The 1,000 cubic yards of moderately impacted soil will be added to the 1,500 cubic yards of asphaltic materials from the tank bottoms pits to be used for dust control material. The 1,250 cubic yards of slightly impacted soil are being successfully bioremediated on site. Bioremediation will continue until the concentrations are less than 100 mg/kg for petroleum hydrocarbons. The treated soil will then be used as backfill material on EB-8228-3 9209-E057.WP Don Keith Transportation 3 September 22, 1992 Soil sampling verified clean sidewalls for the clarifier excavation with the exception of the northeast corner of the excavation (see Appendix B). In this location a 12 inch diameter pipe was observed leading to the northeast, and surrounded by a halo of petroleum impacted soil. Excavation was initiated on September 18, 1992 to expand the pit in this direction. It was soon discovered that a third chamber to the clarifier system was present to the north and east of the original two chamber clarifier (Figure 2). Excavation has continued in this area through September 22, 1992 to establish the dimensions of this third chamber. The third chamber appears to be very similar in size to the original excavation, and also involves approximately 1,000 cubic yards of moderately impacted soil, and 1,250 cubic yards of slightly impacted soil. The 1,000 cubic yards of moderately impacted soil will be added to the 1,500 cubic yards of asphaltic materials from the tank bottoms pits, and the other 1,000 cubic yards of moderately petroleum hydrocarbon impacted soil from the first two' chambers to be used for dust control material. The 1,250 cubic yards of slightly impacted soil are being successfully bioremediated on site. Bioremediation will continue until the concentrations are less than 100 mg/kg for petroleum hydrocarbo The treated soil will then' be used as backfill material on site. "--'~ ! 3.0 PROPOSED REMEDIAL ACTIONS Excavation will continue in the location of the third chamber to .the clarifier system until clean sidewalls are established through field screening. At that time approximately eight soil samples will be collected in the presence of the KCDEHS representative to verify that no addition excavation is required. The tank bottoms excavation pit in the rear of the property will then be backfilled with imported fill material, to make room for the ongoing bioremediation of the slightly petroleum hydrocarbons impacted soil. The bioremediation of this soil consists of daily turning of the 12 inch lift of the soil for a period anticipated to be three weeks. ESE does not envision that supplemental nutrients will be required to obtain the cleanup levels given that a substantial decrease in concentrations are currently being observing during daily field screening. Upon completion of this bioremediation, verification soil samples will be collected to confirm that concentrations of petroleum hydrocarbons within the soil' are less than 100 rog/kg. EB -8228 -3 9209-E057.WP Don Keith Transportation 4 September 22, 1992 This 4,000 cubic yards of soil will then be used to backfill the three chamber clarifier system excavation pit along with enough imported fill to return the excavation to surface grade. The remaining 3,500 cubic yards of asphaltic residuals from the tank bottoms pits and moderately petroleum hydrocarbons impacted soil from the truck wash earthen clarifiers will be thoroughly mixed with the solid asphaltic material pulverized using a Bomag Reclaimer so that no fragment exceeds 2 1/2 inches in diameter. This material will then be applied for dust control to the rear two thirds of the property at a thickness not to exceed three inches (Figure 2).

ESE proposes excavation and bio- reclamation of approximately 1,000 cubic-yards of soils impacted with petroleum based compounds associated with two earthen clarifiers connected to a truck wash rack as well as excavating and disposing of approximately petroleum.r:based~'%l~'d'ge~:~fi~'s'6~:iati~d with the former operation of two tanker truck bottoms disposal pits recently documented by ESE in the above referenced report. After review of the available data, ESE believes the 1,000 cubic yards of impacted soil from beneath the former clarifiers can be treated on-site utilizing biological degradation technologies. The advantages of bio-reclamation is the permanent destruction of the petroleum hydrocarbons, thus minimizing the potential long term liabilities associated with off-site disposal at a hazardous waste facility. The final by- products of biologic degradation of the petroleum hydrocarbons consist primarily of carbon dioxide (CO2) and water. Don Keith Transportation 2 August 14, 1992 We propose the construction of a bio-reclamation treatment system on-site as the most suitable method tbr mitigating the semi-volatile petroleum based compounds and reducing the concentrations of petroleum hydrocarbons within the soils at the above mentioned site to levels considered to be non-hazardous by Regional Water Quality Control Board Central Valley District, and Kern County Resources Management Agency, Department of Environmental Health Services' criteria. Following approval by Kern County Department of Environmental Health Services a biological treatment system will be implemented to treat impacted soils at the site. Upon successful completion of the biological treatment (reduct.ion of total petroleum hydrocarbon concentration to below the acceptable limits), and with the permission of the local governing regulatory agency, we will request that the treated soil be on-site as as grading fill.'~ We anticipate the minimum time frame for spread successful treatment utilizing biological degradation capabilities to be on the order of 2 months. Based on our past experience with similar sites, we believe that the construction of an above ground treatment cell would present the most cost effective and efficient method for remediating the impacted soil. The treatment system is based on enhancing indigenous soil microbes and/or the introduction of cultured specific strains of common microbes suited for the biological degradation of semi-volatile petroleum based hydrocarbons. All methods employed are in compliance with regulations and guidelines set forth in California Code of Regulations (CCR) Title 22, Article 11, and Title 23, Chapter 3, California Site Mitigation Decision Tree Manual, the Code of Federal Regulations (CFR) Title 29, Part 1910, Section 120, CFR Title 40, Parts 300-399, and the San Joaquin Valley Unified Air Pollution Control District, Kern County Zone Rules 463.5 as well as accepted professional environmental/geotechnical engineering procedures and applicable local regulations. EB-8228~3 9208-EO28.WP Don Keith Transportation 3 August 14, 1992 Subject to your acceptance of this work plan, our plan to excavated the soils beneath the former clarifiers and treat the soils with bio-reclamation technology as well as excavating and disposing of the tank bottoms includes: · Preparation of a site Health and Safety Plan in accordance with regulations set forth in Federal OSHA CFR 29 1910.120, as well as California OSHA regulations. · Excavation of approximately 1,000 cubic yards of impacted soil beneath the location of the former truck wash clarifiers. · Excavation of approximately 300 cubic yards of sludge materials within the former tanker truck bottoms disposal pits. · Confirmatory sampling and analysis of the three excavation pit bases and sidewalls. · Backfilling pit with "clean" import fill material, compacting, and returning to surface grade. · Loading and transporting the tank bottoms sludge to an appropriate petroleum waste disposal facility.- . Placement of the clarifier impacted soil in a six inch lift over the rear portion of the property. · Mechanical cultivation increasing oxygenation and enhancing i,ndigenous soil microbes to reduce the concentrations of the petroleum hydrocarbons to beneath RWQCB recommended guidelines. · Progress monitoring and sampling. · Verification sampling and preparation of a final report documenting remediation activities. Subsequently we have developed the following scope of work: Site . Description The site is located at 2990 Pierce Road in the city of Bakersfield in Kern County, California (Figure 1). The site is currently used as a parking area where the tanker trucks are parked. · . EB -8228-3 9208-EO28.WP Don Keith Transportation 4 August 14, 1992 The site is situated within a developed industrial area. Nearby surrounding properties are primarily retail businesses, petroleum service companies, refineries, and actual oil producing properties. The overall site topography is essentially flat, with a very slight fall to the west. BackgroUnd Based on conversations with Chris DeArmon,' two locations on 'the subject property had a potential for subsurface soil impacted with petroleum hydrocarbons and required assessment as part of a baseline environmental assessment at Don Keith's Asphalt and Diesel Transportation Company. The first area is that of a very large, two stage, earthen bottom clarifler system which formerly served the truck wash for the crude oil, asphalt, fuel oil and diesel fuel trucking firm. The clarifiers have been backfilled and no surface evidence remains. The property owner has provided a description of the size of each clarifier, and flagged their boundaries. The second area consists of two disposal pits in the rear of the property which received tanker truck bottoms. The surface of these has been covered with soil, however stained soil is visible at the surface in the location of the two pits. ESE has conducted an initial site characterization consisting of eleven soil borings and laboratory analysis of 27 soil samples to evaluate the extent of petroleum hydrocarbons impacted soil in the vicinity of both the former truck wash earthen clarifiers and tank bottom disposal pits. Subsurface Investigation Drilling of four initial borings was conducted on July 13, 1992. Drilling of seven additional borings to more fully assess the vertical and lateral extent of the impacted soils was conducted on August 6, 1992. A total~ of eleven soil borings were drilled within this phase of soil characterization (Figure 2). One soil boring, TH-1 was drilled on July 13, 1992 through the center of the western of the two former truck wash clarifiers location to a depth of 31 feet below surface grade to assess the potential for petroleum hydrocarbons in the subsurface at that location. On August 6, 1992 this boring was twinned by boring TH-IA which was advanced to a depth of 46 feet to assess the vertical limit of the petroleum hydrocarbons encountered in boring TH-I. A soil boring, TH-2 was drilled on July 13, 1992 through the center of the - ~ EB-8228- 3 9208-E028.WP Don Keith Transportation 5 August 14, 1992 eastern of the two former clarifiers to a depth of 36 feet below surface grade to assess the potential for petroleum hydrocarbons at that location. On August 6, 1992 this boring was twinned by boring TH-2A which was advanced to a depth of 48.5 feet to assess the vertical limit of the petroleum hydrocarbons encountered in boring TH-2. Soil borings TH-3A, TH-4 and TH-4A were advanced around the periphery of the two earthen clarifiers to assess the lateral limits of the petroleum hydrocarbons encountered in borings TH-I and TH-2. Soil boring TH-3A was drilled drilled 35 feet southeast of TH-2 outside of the former eastern clarifier location to a depth_ Of 29,~f&~t~ to assess the the potential for lateral migration of petroleum hydrocarbons in that direction. Soil boring TH-4 was drilled drilled 20 feet north of TH-2 to a dap/J3...~,.~..L~..~6~. feet to assess the the potential for lateral migration of petroleum hydrocarbons in that direction. Soil boring TH-4A was drilled drilled 35 feet southwest of TH-I to a depth of 35 feet~,~o~,,.~assess:.~.,the~.~,,the,:~.potential for lateral migration of petroleum hydrocarbons in that direction. A soil boring, NP was drilled through the center of the northern tank bottom disposal pit location to a depth of 27 feet below surface grade to assess vertical migration of petroleum hydrocarbons at that location. Soil boring TH-3 was drilled drilled 25 feet northeast of NP to a depth of 31 feet to assess the the potential for lateral migration of petroleum hydrocarbons in that direction. A soil boring, SP was drilled through the center of the southern tank bottom disposal pit location to a depth of 36 feet below surface grade to assess vertical migration of petroleum hydrocarbons at that location. Soil boring SPL was drilled drilled 35 feet east of SP to a depth of 21 feet to assess the the potential for lateral migration of petroleum hydrocarbons in that direction. To better define the limits of the two tank bottoms disposal pits a backhoe operated by Kern Environmental Service was used to excavate five foot deep trenches in the rear portion of the property. Upon exposing the limits of the pits a composite soil sample was collected from the sludge within the two pit's at a depth of three feet below surface grade. Laboratory 'Analysis Twenty-six soil samples and one sludge sample were submitted to B. C. Laboratories of Bakersfield, Califorinia for analysis. All twenty-seven samples were analyzed for Total Recoverable Petroleum Hydrocarbons (TRPH) as oil and grease using USEPA Test Method 418.1. Seven of the samples including the tank bottoms sludge were analyzed EB-8228-3 9208-E028.WP Don Keith Transportation 6 August 14, 1992 for California Title 22 metals. Six of the samples including four from the area of the earthen clarifiers, and two from the area of the tank bottoms disposal pits were analyzed for volatile and semi-volatile organics using USEPA Test Methods 8240 and 8270. Five samples including the sludge were analyzed for Total Extractable Petroleum Hydrocarbons as diesel (TEPHd) using the DOHS LUFT Manual Method. Four deeper soil samples beneath the earthen clarifiers were analyzed for total lead using the DOHS LUFT Manual Method. The tank bottom .pit sludge was also analyzed for fuel constituent volatile aromatics using USEPA Test Method 8020, and for pH. Results of the Investigation Geologic Setting Regional Geology: The site is located in the southern part of the Great Valley geomorphic province. The Great Valley is a north-south trending valley, approximately 400 miles long by 50 miles wide. Surface and groundwater in the San Ioaquin Valley is derived predominantly from the Sierra Nevada mountain range to the east, and is transported by five major rivers, the southern most being the Kern River. The subject site is located approximately 1/2 mile northwest of the Kern River. The surface of the San Joaquin Valley is composed primarily of unconsolidated Pleistocene (1.6 million to 11,000 years ago) and Recent (11,000 years ago to the present) alluvial sediments. Beneath the alluvial sediments are older, predominantly lake bed deposits. These lie unconformably on Mio-Pliocene marine sediments which extend to crystalline basement at approximately 20,000 feet. Site Geology: Geologic deposits in the study area include Pleistocene alluvial sediments of the Kern River Formation, which form a homocline dipping gently to the west. The deposits are alluvium consisting of poorly indurated and dissected fan deposits (CDMG, 1964). The depth to the regional unconfined aquifer was estimated prior to drilling to be approximately- 50 feet below surface grade beneath the :rite (Kern County Water Agency, Improvement District No. 4, 1991 Report on Water Conditions, February EB-822'8-3 9208-E028.WP Don Keith Transportation 7 August 14, 1992 1992). .~C,0:oundwater was not encountered in boring TH-2A which~ penetrated to a 9~e~th of 48.5 feet. The deepest samples in the borings were moist, but did not have an indication that the capillary fringe to groundwater was at that depth. Because of the six consecutive years of drought, and the discontinuance by the Kern County Water Agency of using several large water recharge percolation ponds 1/2 mile to the north, a drop in the elevation of groundwater by as ~uch as 25 feet may have occurred in the area. The nearest known occurrence of perched groundwater is 8 miles to the southeast at a depth of 20 feet in the abandoned Kern River channel to the ancient Kern Lake Bed (Kern County Water Agency, 1'991 Water Supply Report, May 1992). No perched groundwater is known to exist beneath the subject site. Subsurface material encountered during drilling was alluvium to the total depth of each boring. The alluvium was characterized by unconsolidated, highly permeable, light brown, silty sand (SM) to a depth of approximately 7 feet, overlying unconsolidated, highly permeable, tan, well graded fine- to coarse- grained sand (SW) to a depth of approximately 23 feet. This is underlain by a sequence of unconsolidated, highly permeable, light tan, fine- to coarse- grained gravelly sand (SW/GW) to a depth of 38. Beneath this is a sequence of unconsolidated, highly permeable, light tan, fine- to coarse- grained sand (SW) to a depth of 43, overlying unconsolidated, highly permeable, light tan, well graded fine- to coarse- grained moderately silty sand (SW/SM) to a depth of approximately 46 feet. This is underlain by a sequence of consolidated, moderate to low permeability, light tan, very clayey silt (ML/CL) to a depth of 48.5 which was the greatest depth~ investigated. Laboratory Analytical Results Total Recoverable Petroleum Hydrocarbons (TRPH) as oil and grease were detected at a concentration of 7,900 mg/kg at 10 feet in boring TH-I advanced through the center of the western clarifier location, but not at 20, 30, 40 and 45 feet in boring TH-lA advanced in the same location. TRPI-I was detected a~t a concentration of 10,000 mg/kg at 10 feet in boring TH-2 advanced through the cenlter of the eastern clarifier location and 40 mg/kg at 20 feet in boring TH-2A, but not a~t 40 and 47 feet in boring TH-2A. TRPH was not detected at depths of 15 and 25 feet in boring TH-3A advanced 35 feet southeast of TH-2 on the outside of the former clarifier location, or at depths of EB -8228 -3 9208-E028.WP Don Keith Transportation 8 August 14, 1992 10 and 20 feet in boring TH-4 advanced 20 feet north of TH-2, or at depths of 10 and 25 feet in boring TH-4A advanced 35 feet southwest of TH-I. However, TRPH was detected at 20 mg/kg at a depth of 35 feet in boring TH-4A. Total Extractable Petroleum Hydrocarbons as diesel. (TEPHd) were analyzed for in the soil samples at. 20 feet in borings TH-IA and TH-2A at concentrations of 19 mg/kg, and 23 mg/kg, respectively. The fuel constituent volatile aromatics m- and p-xylenes were detected at a concentration of 0.006 mg/kg at 10 feet in boring TH-I. The fuel constituent volatile aromatics toluene was detected at a concentration of 0.022 rng/kg at 10 feet in boring TH-2. No other volatile organic hydrocarbons including those which constitute fuels and industrial solvents were detected at or above the minimum detection limit in the four soil samples collected from the clarifier area. No semi-volatile organic hydrocarbons (base neutral and acid extractables) were detected at or above the minimum detection limit in the tour soil samples collected from the clarifier area. Lead was detected at an elevated concentration in one of eight samples from the clarifier area. Total lead was detected at a concentration of 27 mg/kg at a depth of 10 feet in boring TH-2 advanced through the center of the eastern clarifier, but was not detected in boring TH-2A at 20 and 40 feet, at 10 and 20 feet in boring TH-4 position 20 feet north of TH-2, and at 10 feet in boring TH-I or 20 feet in boring TH-lA both located in the center of the western clarifier. Total lead was detected at 2.7 rog/kg at 20 feet in boring TH-lA. The State of California Title 22 Total Threshold Limit Concentration (TTLC) for lead is 1,000 mg/kg. However, thte Soluble Threshold Limit Concentration (STLC) for soluble lead is 5 mg/kg. Because of the 10:1 dilution that occurs during the wet extraction any total concentration less than 50 mg/kg will necessarily be determined to have a soluble component less than the STLC of 5 mg/kg. Therefore, a soluble lead wet extract was not performed on the sample in this investigation with a concentration of total lead detected of 27 rog/kg. ' - EB-8228-3 9208-E028.WP Don 'Keith Transportation 9 August 14, 1992 Arsenic, barium, chromium, cobalt, copper, nickel, vanadium, and zinc were detected in the four soil samples tYom the clarifier area at concentrations typical of the background concentrations for these metals in the soil in the area of the subject property. The other Title 22 metals were not detected in the four soil samples t¥om the clarifier area. Total Recoverable Petroleum Hydrocarbons (TRPH) as oil and grease was detected at a concentration of 45,000 mg/kg is the composite sample of the sludge from at depth of three feet within the tank bottoms disposal pits. Total Extractable Petroleum Hydrocarbons as diesel (TEPHd~was detected at a concentration of 12,000 mg/kg in this sample. The fuel constituent volatile aromatics benzene, toluene, ethylbenzene, and total xylenes were detected at concentrations of 0.013 mg/kg, 0.038 mg/kg, 0.021 mg/kg, and 0.177 mg/kg, respectively. The pH of the sludge was measured at 7.17. TRPH was not detected in the north pit vertical, assessing boring NP at depths of 10, 20 and 25 feet, and in the north pit lateral boring TH-3 at 15 and 25 feet. TRPH was detected in the south pit vertical assessing boring SP at l0 feet at a concentration of 20 mg/kg and 25 feet at a concentration of 60 mg/kg and in the south pit lateral boring SPL at 10 feet at a concentration of 160 mg/kg, but not in vertical assessing boring SP at a depth of 35 feet, or in the south pit lateral boring SPL at 20 feet. The semi-volatile organic hydrocarbon diethyl phthalate was detected at a concentration of 0.1 mg/kg at 15 feet in boring TH-3 advanced adjacent to the northern tank bottoms disposal pit. No other volatile organic hydrocarbons, or semi- volatile organic hydrocarbons were detected at or above the minimum detection limit in the two samples collected from the area of the tank bottoms disposal pits. Lead was detected at an elevated concentration in the sample of the sludge from the disposal pits. Total lead was detected at a concentration of 44 mg/kg. The State of California Title' 22 TTLC for lead is 1,000 mg/kg. However, the STLC for soluble lead is 5 mg/kg. Because of the 10:1 dilution that occurs during the wet extraction any total concentration less than 50 mg/kg will necessarily be determined to have a soluble component less than the STLC of 5 mg/kg. Therefore, a soluble lead wet extract was not performed on the sludge sample. Cadmium was detected at 1.2 mg/kg in the EB-8228-3 9208-EO28.WP Don Keith Transportation 10 August 14, 1992 sludge. Cadmium's TTLC is 100 mg/kg, and STLC is I mg/kg. Copper was detected at 66 rog/kg in the sludge. Copper's TTLC is 2,500 mg/kg, and STLC is 25 mg/kg. Mercury was detected at 0.39 mg/kg in the sludge. Mercury's TTLC is 20 mg/kg, and STLC is 0.2 mg/kg. Nickel was detected at 61 mg/kg in the sludge. Nickel's TTLC is 2,000 mg/kg, and STLC is 20 mg/kg. Vanadium was detected at 87 mg/kg in the sludge. Vanadium's TTLC is 2,400 mg/kg, and STLC is 24 mg/kg. Each of these concentrations are far below their respective regulatory, limits. Therefore, the sludge is not classified as a hazardous material by RCRA and California Title 22 criteria. However, these concentrations are in excess of that which occurs in the native soil and indicates an accumulation from the petroleum products. There may be a minor amount of mobility for these metals t¥om the sludge into the underlying soil, however this has not been observed in the investigation. The Regional Water Quality Control Board provides recommended guidelines for TRPH as oil and grease, TEPH as diesel, the fuel constituent volatile aromatics, benzene, toluene, ethylbenzene and total xylenes, and the semi-volatile organic hydrocarbon diethyl phthalate using the LUFT methodology by multiplying the most stringent current federal or state water quality standards by a factor of 100 to account for attenuation due to site-specific parameters including vertical separation to ground water, soil lithology, fractures in subsurfaces, annual average precipitation, and any direct conduits to groundwater.

EB-8228-3 9208-E028.WP Don Keith Transportation 12 August 14, 1992 Conclusions of the Investigation The data obtained suggest that soil impacted beneath the former location of the truck wash earthen clarifiers has been impacted by petroleum hydrocarbons, at concentrations in excess RWQCB recommended guidelines to a depth of less than 20 feet below surface. The data does not indicate that fuel constituents, solvents, or heavy metals have impacted this soil. ESE concludes that the petroleum hydrocarbons detected represent heavier molecular weight crude oil and refined products devoid of known hazardous constituents. The lateral extent of this impacted soil does not extend laterally from the 'boundaries of the former clarifiers. Therefore, ESE estimates that the soil between the base of the former clarifiers at a depth of 8 feet to a depth of 18 feet has concentrations of TRPH as oil in grease in excess'of the recommended guidelines over an area 75 feet long by 40 feet wide for a volume of impacted soil of approximately 1,000 cubic yards. It is ESE's oppinion that excavation of the soil to these dimensions will removal all of the impacted soil with concentrations of TRPH as oil and grease in excess of 100 mg/kg. The operation of the tank bottoms disposal pits appears to have impacted the soil to a depth of less than 5 feet at the location of the pits. The data does not indicate that fuel constituents, solvents, or heavy have impacted this soil. However, the sludge does contain slightly elevated concentrations of heavy metals, but remains classified as non-hazardous by RCRA and California Title 22 criteria. ESE concludes that the petroleum hydrocarbons detected represent heavier molecular weight crude oil and refined products. The lateral extent of this impacted soil does not extend laterally from the boundaries of the disposal pits. Theretbre, ESE estimates that the soil within the northern pit to a depth of 5 feet has concentrations of TRPH as oil in grease in excess of the recommended guidelines over an area 30 feet long by 25 feet wide for a volume of impacted soil of approximately 140 cubic yards, and soil within the southern pit to a depth of 5 feet over an area 55 feet long by 15 feet wide for a volume of approximately 150 cubic yards. It is ESE's oppinion that excavation of the soil to these dimensions will removal all of the impacted Soil with concentrations of TRPH as oil and grease in excess of 100 mg/kg. EB-8228-3 9208-E028.WP Don Keith Transportation 1 3 August 14, 1992 Recommen~lations of the Investigation ESE recommends excavation and surface bioremediation of the soil beneath the former clarifiers, and excavation and off-site disposal of the sludge from the disposal pits. The impacted soil t¥om beneath the former clarifiers should be excavated to a depth 18 feet and treating~ the soil to concentrations less than the RWQCB recommended guidelines through the process of bioremediation at the subject property. Surface bioremediation has been shown to be particularly successful in the San Joaquin Valley given the high temperature, and low relative humidity. This option is particularly viable at this site since the facility has available land to treat the soil., The impacted soil beneath the former clarifiers will respond very well to surface bioremediation. Because the property is in a commercial/petroleum setting, there is only a slight risk of exposure of any off site population to volatilized petroleum hydrocarbons, and therefore very little health risk to the general public associated with the treatment. This option can be particularly attractive since on site treatment alleviates the clients future liability for the soil. On-site treatment is not recommended for the sludge from the disposal pits because it will require an inordinate amount of time and effort for bioremediation to reduce the concentrations to below the RWQCB recommended guidelines· The impacted soil from beneath the former disposal pits should be excavated to a depth of 5 feet where the site assessment indicates that the limits of concentrations ...... ia--e~e~.~.~f the RWQCB recommended guidelines will have been reached~ Selection of / ....... an appropriate recycling or disposal facility depends on the concentration of I contaminants in the soil after it is' stockpiled. Judging from the findings of this study, it appears likely that the semi-solid/semi-liquid state of the sludge from the ~ disposal pits makes that material unacceptable to solid waste recycling facilities. It is \,, ESE,s opinion that the appropriate classification for this material is as a designated ~ atPetroleum waste, and that the sludge materials may be disposed of as non-hazardous a petroleum waste landfill such as the McKittrick Waste Disposal Site. · , O~/L~ 9208 E028 WP Don Keith Transportation 14 August 14, 1992 HEALTH & SAFETY PLAN A written Health and Safety plan will be implemented for site work conducted during the mitigation phase of this project. The purpose of the plan is to provide specific safety procedures to be implemented during the handling of petroleum hydrocarbon contaminated materials. The Health and Safety Plan is required under regulations set forth in Federal OSHA CFR 29 1910.120, since the referenced report documented the presence of potentially hazardous materials at the site. This Health and Safety plan is included as Appendix A to the work plan. REMEDIAL ACTION PLAN Soil Excavation Kern Environmental Services will provide front/?:~n~-~.ers,/? ~? ' and a self-elevating paddle wheel scraper to excavate the estimated(l,00~cub~c2 yards of impacted soil beneath the the two former clarifiers, and the 300 "etrb% yards of tank bottoms within the former disposal pits. Based upon Regional Water Quality Control Board Recommended Guidelines, and Kern County policy, ESE proposes an action level of 1,000 ma/kg for the maximum concentration of Total Recoverable Petroleum Hydrocarbons (TRPH) as oil and grease. Subsequent to the Kern County Resources Management Agency, Department of Environmental Health Services approval, soils will be excavated until the soils remaining in-place are believed to have concentrations of TRPH as oil and grease'less than 1,000 ma/kg. However, the additional excavation required to remove all impacted soil with concentrations of TRPH as oil and grease in excess of 100 ma/kg is relatively insignificant. It is ESE's opinion that the proposed excavation dimensions will remove all impacted soil with concentrations in excess of 100 ma/kg. Prior to excavation, Underground Service Alert (USA) will be notified 48 hours in advance. In addition, the excavation contractor will obtain any necessary excavation permits from California Occupational Safety and Health Administration (Cal OSHA). The excavation will be performed so that sidewall slopes conform to California and Federal OSHA code requirements. ~1 EB-8228-3 9208-E028.WP Don Keith Transportation 15 August 14, 1992 Mitigation of dust is an important concern during the excavation and positioning of soil during this project. Water trucks will be on-site to wet traffic paths to control all dust emissions. Excavation Air Emissions Volatile aromatic hydrocarbons may b'e emitted during the excavation and placement of the semi-volatile petroleum impacted soil at the site. However, a review of the available analytical data indicates that the profile of petroleum hydrocarbons impacting the soil qualifies for an exemption to air emissions permitting as described in the San Joaquin Valley Unified Air Pollution Control District Kern County Zone Rule 463.5. The fuel constituent volatile aromatic benzene has been detected in only one of the soils samples during the investigation. Benzene was detected in that sample at a trace concentration of 0.013 rog/kg. Assuming that the entire mass of benzene within the impacted 'will volatilize in the first day of aeration, then less than 0.05 pounds of benzene will be emitted in that day. This is an overly conservative approach, since excavation will likely require several working days. Because the emission of benzene for that day will be less than 0.05 pounds per day, the site qualifies for an exemption as described in Rule 463.5. The methodology of the California Air Pollution Control Officers Association (CAPCOA) "Screening Level Risk Assessment" indicates that the maximum potential emission of benzene over the duration of the project does not present a public health risk. The soil was impacted with heavier molecular weight petroleum hydrocarbons including crude oil, asphalt fuel oil and diesel, all of which have a boiling point greater than 400°F. Since the boiling point is greater than 302°F, the project qualifies for an exemption under Rule 463.5 Therefore the entire 1,000 cubic yards of impacted soil may be excavated and placed onto the uncovered treatment pad during one continuous time period. EB -8228 -3 9208-E028.WP Don Keith Transportation 16 August 14, 1992 Excavation Pit Field Screening During excavation soil samples will be collected from the base and sidewalls of the three proposed excavation pits, and will be screened for total organic vapors with a portable photoionization detector (PID). Headspace vapor analysis will be performed by filling a mason jar to 50% capacity to produce a head space allowing volatilization for a period of 15 minutes, and protruding the probe of the PID through the cap and into the headspace for analysis. The PID readings will be recorded on the dai!y lo_g~ When field screening indicates concentrations less than 100 ppm,~he excavation Will be discontinued. Otherwise excavation will continue until field screening indicates (i') concentrations less than 100 ppm. ~_L/.J-~' /(~,~c.-~ "~0() Soil Sample Collection Following excavation twelve verification soil samples will be collected from the base and sidewalls of the excavation pit at the location of the former truck was clarifiers. At this time ESE estimates that given the final excavation dimensions required to excavate the approximate 75 toot by 40 foot by 20 toot plume of impacted soil will require at least two samples from each of the four sidewalls, and four samples from the excavation base so that each sample represents less than 200 square feet of surface area. ESE also estimates the five soil samples will be required at the location of both of the former tank bottoms disposal pits with a sample from the center of the base of the excavation at each pit , and a sample from each of the four sidewalls at both pits. The soil samples will be collected in brass sleeves filled in such a way that no headspace remains, immediately sealed with Teflon® film, capped, security taped, labeled, and placed on ice for transport to a California Department of Health Services (DOHS) certified laboratory at less than 4°C. Strict chain of custody procedures will be utilized for all samples collected to ensure sample integrity and to document sample possession t¥om the time of collection to the final destination. All sampling equipment will be washed with TSP (tri-sodium phosphate) cleanser, and rinsed with tap water and de-ionized water prior to sampling, between sample intervals to minimize the possibility of cross-contamination.

Backfill and Compaction The excavation pits resulting from soil removal will be backfilled with the "clean", over excavated soil, and enough import soil to replace the removed impacted soil. The soil will be compacted to 90% relative compaction in 12 inch lifts under the direction of an on-site soils engineer. Compaction tests will be performed on each lift from the base of the excavations to the surface. Backfilling will be accomplished using an 815 mechanical compacter, a 966 loader, and a water truck. A report will be prepared by the Earth Systems Consultants which certifies that the excavation was backfilled in such a way that the compaction exceeds 90%, and provide the compaction test reports as documentation. Soil Loading and Transportation KES will provide a front end loader to load the estimated 300 cubic yards of tank bottoms sludge at the site into approximately sixteen 20 yard end dump trucks operated by KES's affiliated company, KVS Transportation, Inc. Non-hazardous Wastes Manifests will be prepared by/. KES and signed by Don Keith Transportation's authorized representative at the site..'xf Each of the 20 yard end dump trucks will be lined with visqueen plastic sheeting and covered with a tarpaulin prior to leaving the site location. Upon leaving the site, the trucks will enter the right hand lane of south bound Pierce, and proceed I/8 mile south to the intersection of Pierce Road and Rosedale Highway. The trucks will then proceed west on Rosedale Highway to Highway 33 were they will proceed south to the entrance of the Mckittrick Waste.,,..~. Disposal Site. ESE will provide supervision of the loading 'and transportation process. The ESE supervisor will assure that all of the stockpiled tank bottoms sludge is removed from the site. The stockpiled soil will be removed in such a way that a one inch' layer of "clean" soil from beneath the removed visqueen plastic sheeting will also scraped up and included with the sludge, for disposal. The native soil base will then observed for --- EB-8228-3 9208-E028.WP Don Keith Transportation 18 August 14, 1992 any evidence of discoloration, or odor. If none is observed, then it will be determined that all of the soil which had been stockpiled has been removed~ Remediation of Petroleum Impacted Soil The 1,000 cubic yards, of soil excavated from beneath the former truck wash clarifiers will be spread out over the rear portion .of the property in a six inch lift. A berm will be constructed surrounding the treatment area to a minimum height of 2 feet and width of 3 feet at the toe of slope. Once soils have been placed within the treatment area mechanical cultivation will be initialed to increase the oxygenation of the hydrocarbons, ~nd enhance the indigenous microbes. , The final by-products of biologic degradation of the petroleum hydrocarbons will consist primarily of carbon dioxide (CO2) and water. We estimate the placement of the soil within the treatment area can be performed within the time frame of approximately three days with- obtainment of the proscribed RWQCB clean up levels within a two month period. The bioremedial system will utilize active mechanical cultivation by a tractor and plow or dozer and ripper combination. Tilling of the stockpiled material would be conducted on a weekly basis. Treatment Cell:. Interim and Verification Soil Sampling The progress of the treatment will be monitored periodically by an assistant geologist or engineer using a OVM photo-ionization detector (PID) or a Foxboro® OVA (organic vapor analyzer) 108 flame-ionization meter. Approximately two interim soil sampling events will be conducted and soil samples analyzed to evaluate the progress of the treatment process. Verification soil sampling will be accomplished with a 2.5-inch diameter hand held ring sampler equipped with stainless steel liners for soil retention. Soil samples will be collected upon setup of the system to obtain initial concentrations and at periodic intervals, as well as for final verification of treatment. When contaminant levels are thought to be acceptably low (to specified clean-up level or less), the soil stockpile will be sampled in the presence of a representative of the Kern County Department of Environmental Health Services. Soil samples will be sealed with Teflon® film, EB-8228-3 9208-E028.WP Don Keith Transportation t9 August 14, 1992 capped, and placed on ice for transport to a California Department of Health Services (DOHS) certified laboratory. Strict chain of custody procedures will be utilized for all samples collected to ensure sample integrity and to document sample possession from the time of collection to the final destination. All sampling equipment will be washed with TSP (tri-sodium phosphate) cleanser, and rinsed with tap water and de-ionized water prior to sampling, between sample intervals to minimize the possibility of cross-contamination. Laboratory Analysis of Soil Samples We anticipate a total of 4 to 5 soil samples will be collected during each sampling interval. We anticipate the final verification sampling may require at least 10 soil samples. Soil samples will be sent to a state-certified laboratory for chemical analysis. Soil samples will be analyzed for Total Recoverable Petroleum Hydrocarbons as oil and grease by USEPA Test Method 418.1. Treated Soil Disposition The clean treated soil will be used as grading fill on the subject property. The treated soil will be spread at a thickness of no greater than two inches over the property. Report Preparation The project manager will prepare a final report documenting the results of the soil treatment which will be sent to the client. The final report will be signed by a Registered Geologist and will contain a summary of the installation and treatment activities, required permits, a site map showing soil sample locations, description of methodologies used, certified laboratory reports and chain of custody documents. A request will be made for closure of the case at this time. Schedule and Conditions It is expected that the excavation and backfilling of the excavation pits, transportation and disposal of the tank bottoms sludge, and placement of impacted soil in the treatment area will be completed within two weeks of approval from the Kern County Department of Environmental Health Services to proceed. EB-8228-3' 9208-E028.WP Don Keith Transportation 20 August 14, 1992 We anticipate that-the soil will be monitored once every two weeks with a OVA, with the first interim sampling to be conducted approximately 3 weeks from the initial construction. Verification sampling will be conducted in the presence of the Kern County Department of Environmental Health Services representative ~e. Jy 45 days after initiating soil treatment. A final report will be submitted to the client and the Kern County Department of Environmental Health Services upon verification that clean up levels have been obtained. With approval of the Kern County Department of Environmental Health Services the remediated soils will be used as grading fill on- site. Thank you for your consideration of this work plan.

Sure B APPENDIX A SITE ttEALTH AND SAFETY PLAN SITE HEALTH AND SAFETY PLAN SITE DESCRIPTION The site is located at 2990 Pierce Road in the city of Bakersfield in Kern County, California (Figure 1). The site is currently used as a parking area where the tanker trucks are parked. The site is situated within a developed industrial area. Nearby surrounding properties are primarily retail businesses, petroleum service companies, refineries, and actual oil producing properties. The overall site topography is essentially t'lat, with a very slight fall to the west. BACKGROUND Two areas have been identified on the subject property where soil has been impacted by petroleum hydrocarbons in excess of RWQCB guidelines. Remedial actions are planed including the excavation and on-site surface bioremediation of approximately 1,000 cubic yards of soil from beneath two former earthen clarifiers associated with a truck wash rack, and the excavation and disposal of approximately 300 cubic yards of tank bottoms sludge from two former disposal pits. PURPOSE The purpose of this plan, which was developed specifically for operations at the referenced site, is to assign responsibilities, establish personnel protection standards and mandatory safety procedures, and provide for contingencies that may arise while removal, and bioremediation of the diesel impacted soil are being conducted at' the site. This plan complies with, but does not replace, Federal Health and Safety Regulations as set forth in 29 CFR 1910 and 1926, California Health and Safety Regulations set forth in Title 8, California Code of Regulations, and guidance established by the California Department of Health Services. This plan is to be used by ESE as a supplement to such rules, regulations, and guidance. Don Keith Transportati°n 2 August 14, 1992 APPLICABILITY The provisions of the plan are mandatory for all on-site ESE employees engaged in activities known to be or potentially associated with the presence of hazardous materials. These activities may include, but are not limited to, mobilization, project operations, and demobilization. Changes and/or unanticipated site conditions may require modification of this Site Health and Safety Plan (SHSP) in order to maintain a safe work environment. Any proposed changes to this plan should be reviewed by the Corporate Health and Safety Officer of ESE, prior to their implementation. If this is not feasible, the project team leader may modify the plan' and record all changes in the field log book. Under no circumstances will the plan modifications conflict with Federal, state, or local health and safety regulations. Under 29 CFR 1910.120 (b) (15) ESE is required to notify each subcontractor of the hazardous materials identified by ESE. The acceptance of such responsibility does not and shall not be deemed an acceptance of responsibility for any other health and safety requirements, such as those related to excavating, trenching, drilling or backfilling. Each subcontractor shall perform all work in accordance with a Site Health and Safety Plan for its employees, which covers any exposure to hazardous materials which may be present on site. The subcontractor shall hold ESE harmless t¥om, and indemnify it against, all liability in the case of any injury or injury of its own employees. ESE reserves~ the right to review the subcontractor's Site Health and Safety Plan at any time._ ESE reserves the right 'to suspend the subcontractor's si'te work and ask the subcontractor's personnel to evacuate the hazard area in the event of grossly inadequate health and safety precautions on the part of the subcontractor or the belief that the subcontractor's personnel are or may be exposed to an immediate health hazard. EB-80228-3 9208-E0328.WP Don Keith Transportation 3 August 14, I992 KEY PERSONNEL AND RESPONSIBILITIES The key personnel and their responsibilities for this project are as follows: Corporate Health and Safety Officer The ESE Corporate Health and Safety Officer (CHSO) for this project is Mr. Robert Mohle. It is his responsibility for developing and coordinating the ESE health and safety programs.

SITE INFORMATION All field activities will take place on the Don Kieth Transportation Company, 2990 Pierce Road property. All excavation activities will take place in the daylight hours between 7:00 A.M. and 7:00 P.M. The presence and location of potentially hazardous materials, which are hydrocarbon compounds, has been confirmed through previous investigation. If needed, three blasts of a horn will be sounded for site evacuation. This site information is current and has been verified through analytical testing. EB-80228-3 9208-EO328.WP Don Keith Transportation 5 August 14, 1992 HAZARD ASSESSMENT Hazardous Materials Hazardous materials may be a health hazard to site personnel via ingestion, skin absorption, or inhalation. Biohazards or accidental ingestion of contaminants may occur via hand-to-mouth actions. Dust inhalation may also contribute to ingestion of chemical contaminants. During excavation, soil sample collection, and sample preparation, inhalation of contaminant vapors could occur. Skin absorption may occur via contact with contaminated soil and/or ground water. The degree of hazard depends upon the adverse characteristics and toxicity of the chemical contamination, the amount of potential contact, and the exposure time. The greatest potential for chemical hazard to site personnel is during excavation activities. The following substance is potentially a chemical hazard at the subject site: Substances Involved Physical State Characteristics Petroleum Compounds Liquid/Absorbed Irritant The following materials potentially present at this project site are specified by California Health and Safety Code 25249.5 as recognized and confirmed by the State of California as carcinogenic and/or mutagenic: l. Petroleum Compounds containing benzene. Potential Worker Hazards With hydrocarbon-based liquids, contact may result in dermal irritation due to desiccation. Respiration of air laden with hydrocarbon vapors may result in oxygen deficiency and/or mucous membrane irritation. Mixtures of air and hydrocarbon fuels exhibit an explosive range thus presenting an explosion hazard. Petroleum compounds may contain minor amounts of benzene, a proven human carcinogen. Potential exposure values and limits for benzene are listed in the table below. EB-80228-3 9208-E0328.WP Don Keith Transportation 6 August 14, 1992 TABLE I - POTENTIAL EXPOSURE VALUES Chemical Highest Conc. IpI TLV2 IDLH3 Flammable Detected in (electron (ppm) Level Range Samples (p.pm) volts) (percent) Benzene 0.013 0.9245 10 Carcinogen~ 1.3 - 7.1 l lomzation Potential in electron volts (eV) 2Threshold Limit Value as the time-weighted average (TWA) published by the American Conference of Governmental Industrial Hygienists (ACGIH) 3Immediately dangerous to life and health (IDLH) level as published by National Institute of Occupational Safety and Health (NIOSH), Publication Number 85-114, September 1985. NA: not available Benzene is a colorless liquid with an aromatic odor. It is incompatible with strong oxidizers like chlorine or bromine with iron. The routes of exposure tbr benzene include inhalation, skin absorption, ingestion, and skin and/or eye contact. Symptoms of exposure to benzene include irritation to the eyes, nose, and respiratory system, giddiness, headache, nausea, staggering gait, fatigue, anorexia, lassitude, dermatitis, and abdominal pain. The potential health hazard from benzene exposure is very slight at' this site. Conditions for Suspension of Operations Site monitoring equipment will include a Photo-ionization detector (PID) or a Flame- ionization detector (FID) during drilling and trenching. Field activities at Level D will be suspended when the continuous FID or PID level in the breathing zone increases to ten times background levels (assuming an ambient range of five to ten ppm). Level of Protectiola The level of Personal Protection Equipment (PPE) needed for this investigation is Level D. Level D PPE includes coveralls, leather boots with steel toes and shanks, eye protection, safety helmet and gloves. If warranted, this Site Safety Plan can be EB-80228-3 9208-E0328.WP Don Keith Transportation 7 August 14, 1992 modified tbr use of Level C situations. Modification to Level B or Level A is beyond the scope for this Site Safety Plan and is not permitted. The criteria for upgrading to Level C PPE is the detection of unknown gasses or vapors in concentrations greater than 10 times background levels or unknown liquids present within the work area. Level C PPE includes Tyvek suits, nitrile gloves and rubber boots, eye protection, hard hat, and a full-face air-purifying respirator with Scott 642-OA-H cartridge-filters or equivalent. Physical Hazards Excavation equipment will be working near petroleum pipelines. All workers will be positioned upwind t¥om operating equipment at all times. Excavation Sloping Contaminated soils in the areas identified by ESE will be removed by excavating with a backhoe. Excavating will proceed to the maximum depth of 20 feet below grade, if necessary. It is recommended that all open excavations be fenced. The sidewalls for all excavations will be designed to protect employees working in excavations from cave-ins and be in accordance with Federal OSHA requirements in 29-CFR Part I926, Appendix B to Subpart P. The maximum allowable slope for each excavation will depend on the soil type and shall be determined from Table B-1 in 29 CFR Part 1926. The actual slope of the excavations will be less than the maximum slope, when there are signs of distress. If this situation occurs, the slope will be cut back to an actual slope which is at least one-half horizontal to one vertical (1/2 H: 1 V) less steep than the maximum allowable 'slope. Slips, Trips and Falls All field personnel shall become familiar with the general terrain and potential physical hazards (ravines, potholes, and loose gravel) which would be associated with accidental risk to slips, trips and/or falls. EB -80228 -3 9208-E0328.WP Don Keith Transportation 8 August 14, 1992 Splashes and Spills All field personnel shall wear appropriate chemical resistant gloves and goggles to prevent potential dermal exposure to accident splashes and spills that may occur during excavation of contaminated soil and soil sampling. Sunburn Working outdoors on sunny days for extended periods of time can cause sunburn to the skin. Excessive exposure to sunlight is associated with the development of skin cancer. Field staff should take precautions to prevent sunburn by using sun-screen lotion and/or wearing hats and long-sleeved garments. Heat Stress Heat stress can be a major hazard, especially for workers donning personnel protective equipment (PPE). The same protective materials that shield the body from chemical exposure also limit the dissipation of body heat and moisture. Heat stress can occur very quickly, depending on the work being performed, the ambient weather conditions, clothing, and the individual characteristics of the worker. Because heat stress is probably one of the most common (and potentially serious) illness at hazardous waste sites, regular monitoring and other preventive precautions'are vital. Heat stress monitoring should commence when personnel are wearing PPE, including Tyvek-type coveralls, and the ambient temperature exceeds 70°F. If impermeable garments are not worn, monitoring should start when the temperature reaches 85°F. The . following monitoring program is for workers wearing semipermeable or impermeable encapsulating ensembles when the temperature in the Work area is above 70°F: Heart Rate should be measured by the radial pulse during a 30 second period as early as possible in the rest period. The next work cycle should be shortened by one-third while the rest period is kept the same, if the heart rate exceeds 110 beats per minute. If the heart rate still exceeds 110 beats per minute at the beginning of the next rest period, shorten the following work cycle by one- third. EB-80228-3 9208-E0328.WP Don Keith Transportation 9 August 14, 1992 Preventing heat stress is particularly important because once someone suffers from heat stroke or heat exhaustion, that person may be predisposed to additional heat injuries. To avoid heat stress, the following steps may be taken: · Modify work/rest schedules according to monitoring requirements, and mandate slowdowns as needed. · Alternate .personnel assigned to particular tasks to minimize over stress at one job function. · Add additional persons to work team, and work during cooler hours, if possible. · Provide shelter or shaded areas, to protect personnel during rest periods. · Maintain workers body fluids to ensure that the cardiovascular system functions adequately by having workers drink 16 ounces of fluid (preferably water) before beginning work, and urge workers to drink at least 16 ounces of fluid during each rest period. · Encourage workers to maintain an optimal level of physical fitness. An initial work/rest cycle on one hour work and fifteen minutes rest is recommended for protection of staff when the heat stress hazard is high. The recommended cycle will be adjusted up or down based upon worker monitoring, environmental conditions, and the judgement of the site safety officer. At any time field team members recognize the signs or symptoms of heat stress prior to a scheduled rest period, they will notify the site safety officer immediately in order that a rest period can be called. Some of the signs and Symptoms of heat stress are heat rash, heat cramps, heat exhaustion, and heat stroke. Heat rash is characterized by a decreasing ability to tolerate heat and skin irritation and may result from exposure to heat or humid air. Skin cleanliness and treatment with mild drying lotions are necessary to prevent infection. Heat cramps are caused by heavy sweating with inadequate electrolyte replacement and are characterized by muscle spasms and pain in the hands, feet, and abdomen. Treatment of this disability consists of administering salted liquids orally. EB-80228-3 9208-E0328.WP Don Keith Transportation 10 August 14, 1992 Heat exhaustion may result form physical exertion in a hot environment when cardiac output is inadequate to meet increased flow of blood that results from dilation of peripheral blood vessels or dehydration. It is distinguished by pale, cool, moist skin, heavy sweating, dizziness, nausea, and fainting. First aid for heat exhaustion is as follows: I. Immediately remove victim' to support area, or if you are the victim, proceed to the support area. 2. Decontaminate, if practical, before entering' support area. 3. Start cooling, but be careful not to cause a chill. 4. If conscious and not in shock, give water to drink slowly. 5. If vomiting, and/or signs and symptoms are not lessening within an hour, call for emergency help and/or transport victim to emergency room. 6. If person is a victim of heat exhaustion, they should not work the remainder of the day. The most serious form of heat stress is heat stroke. This is caused when the temperature regulation fails and the body temperature rises to critical levels. Immediate action must be taken to cool the body before serious injury and death occur. Red, hot, usually dry skin, lack of reduced perspiration, nausea, dizziness and confusion, strong, rapid pulse, and coma are the signs and symptoms of heat stroke. First aid for heat stroke is as tbllows: 1. Immediately move victim to cool, uncontaminated area, the support area, and remove and dispose of victim's chemical-resistant clothing, if wearing any. 2. Cool the victim rapidly using whatever means necessary. This can include, but may not be limited to, removing clothing, fanning, and placing in water. 3. Do not give drinking water to victim. 4. Treat for shock, if needed. 5. Transport the victim to a medical facility immediately for further cooling and monitoring of body functions. EB -80228 -3 9208 -E0328.WP Don Keith Transportation 1 1 August 14, 1992 Cold Stress Cold stress is a particular concern when field activities are performed while the air temperatures at the site are below 40°F. If winds are blowing at 5 mph or grater and/or the weather is damp or wet, cold stress is even more of a potential hazard. Donning of appropriate clothing, having warm shelter readily available, carefully scheduling work and rest periods, and monitoring workers' physical conditions are precautions that will be taken to prevent cold stress. Cold injury (frostbite and hypothermia) may occur if cold stress is not prevented. As a preventive measure, the body core temperature must not drop below 96.8°F. Pain in the extremities is the first early sign of cold stress. Severe shivering sets in when the body core temperature drops below 95°F. If this occurs, work will stop immediately and the affected worker(s) will take a warming break of sufficient duration that the signs and symptoms of cold stress go away. Noise Heavy equipment, such as excavators, may produce loud noise.. The effects of noise can include, but may not be limited to: · Distracted, annoyed, or startled workers. · Physical damage to the ear, pain, and temporary and./or permanent hearing loss. · Communication interference that may increase potential hazards due to the inability to warn of dangers and the proper safety precautions to be taken. OSHA regulation 29 CFR Part 1910.95 describes an effective hearing conservation program that must be administered whenever noise exposures equal or exceed an 8- hour, time-weighted average sound level of 85 dBA (decibels on the A-weighted scale). In addition, if workers are subjected to noise exceeding an 8-hour, time- weighted average sound level of 90 dBA, feasible administrative or engineering controls must be utilized. EB-80228-3. 9208-E0328.WP Don Keith Transportation 12 August 14, 1992 Heavy Equipment and Excavating Before beginning any site work, the excavator subcontractor will pertbrm a safety inspection of the excavation equipment. Personnel shall not work with equipment that they judge to be unsafe because of deterioration, missing parts, obvious defects, or improper use for site conditions. All equipment shall be bonded and grounded, sparkproof, and explosion-resistant, as appropriate. Operation of excavators or other heavy equipment in areas with steep embankments or 'unstable ground will be avoided, if possible. The subcontractor will make appropriate provisions to ensure safe operation of equipment, if it is necessary to operate equipment in these areas. ANSI-approved hardhats must be worn at and near the excavator or any other heavy equipmem. Since heavy pieces of equipment will be used during excavation, steel- toed boots/shoes are required during drilling operations, as well as during operation of other heavy equipment. The excavator must maintain a safe clearance (at least 10 feet) between overhead utility lines and the excavation machinery at all times. Underground Utilities The general engineering contractor will locate all underground utility locations prior to the starting of excavation activities. Resources used include site plans, utility companies, and Underground Services Alert (USA). In California, USA must be contacted at least two, but not more than fourteen, days prior' to excavating on public property. MEDICAL MONITORING All Earth Systems Environmental, Inc. (ESE) employees assigned to the sampling operations must be active participants in ESE Employee Medical Surveillance Program, which meets the requirements of 29 CFR 1910.120. ESE's program requires employees assigned to hazardous waste site investigations and remediation to take pre-assignment, annual, and exit medical examinations. The CHSO will maintain - - EB-80228-3 9208-E0328-WP 'Don K¢ith .Transportation 13 August 14, 1992 current copies of training certificates and statements of medical program participation for all site personnel. Work-Rest Schedule. Depending on the prevailing temperature and humidity, a work-rest schedule may be necessary. Duration and frequency will be at the discretion of the excavator and/or site supervisor. A supply of potable water will be kept available near the site. Safety Training. Field personnel must receive 40-hour basic health and safety training, designed to comply with the OSHA/EPA requirements for hazardous waste operations and eight hours of annual refresher as set forth in 29 CFR 1910.120, and attend a site-specific safety orientation conducted by the project supervisor. The briefing shall include the following: 1) A briefing on the work to be performed and the work schedule 2) A discussion of the potential chemical and physical hazards associated with the work to be performed 3 ) Hazard identification 4) Purpose and limitations of personal protective equipment 5) Decontamination and emergency response procedures 6) Proper on-site conduct. EMERGENCY CONTACT AND PROCEDURES Contacts Should any situation or unplanned occurrence require outside or support services, the appropriate contact from the following should be made: Agency Person to Contact Telephone Ambulance disPatcher 911 County Fire Department dispatcher 911 Police dispatcher 91'1 Mercy Hospital dispatcher (805) 326-2620 Dept. of Environ.

Proceed one mile south on Oak Street to Truxtun Avenue,. and turn left. Proceed east on Truxtun Avenue following the signs to the emergency entrance of the hospital at 2215 Truxtun Avenue which will be on the right (south side of Truxtun Avenue in Bakersfield). Paramedics should be summoned in the event of a serious injury; they will arrange to transport the victim to the nearest appropriate facility. A first aid kit will be available at the site for use in case of minor injuries. If anyone receives a splash or particle in the eye, the portable eyewash will be used to irrigate the eye for 15 minutes. If direct contact with contaminants occurs, affected skin areas should be washed immediately with soap and water. At least one person at the site will have current certification in First Aid and CPR. SITE LAYOUT The level of hazard associated with the work to be performed does not require dividing the site into formal exclusion, contamination reduction, and support zones. However, care will be taken to avoid breathing vaporized petroleum hydrocarbons. CONTAMINATION MONITORING Organic vapor monitoring of the ambient air shall be conducted at reasonable intervals as determined by project personnel. The purpose of monitoring is to determine if vapor levels in the work area are high enOugh to warrant personal protection measures or evacuation of the site. Organic vapor levels should be monitored using an OVM photoionization meter with an 11.7 eV lamp (probe), calibrated to benzene or a Foxboro® OVA (organic vapor analyzer) 108 flame-ionization detector calibrated for non-methane hydrocarbons. Background should be determined by taking readings before sampling begins. All readings, background and others, must be recorded. If any continuous measurement EB.80228_3 9208-E0328.WP Don Keith Transportation 15 August 14, 1992 is observed to be I0 times over background levels in the work area, respiratory protective action will be required. Lesser protective measures are at the field geologists or engineers discretion. DECONTAMINATION Before leaving the site/work area, personnel must remove all protective equipment and wash their hands, faces and necks. These washing procedures shall be observed before all work breaks. To minimize the potential for cross-contamination, all excavation equipment shall be decontaminated before the start of drilling, between borings, and before removal from the site. Sampling equipment shall be decontaminated before sampling and between sampling with washing with laboratory-grade detergent, a water rinse and a contaminant-free distilled water rinse. EMERGENCY PROCEDURES Emergency conditions are considered to exist if: * Any member of the field crew is involved in an accident, experiences any adverse effects or symptoms of exposure while on-site; or * A condition is discovered that suggests the existence of a situation more hazardous than anticipated. In the event of an on-site emergency, the procedures described below are to be immediately followed. 1. Personnel on-site should use the "buddy system" (stay in pairs). In the event of a communication breakdown, i.e. radio malfunction or if radios are not available, "buddies" should use prearranged hand signals or other means of emergency signals as follows: * Hand gripping throat - out of air, can't breath. * Grip partner's wrist or place both hands around waist - leave area immediately, no debate! EB -80228 -3 · 9208 -E0328.WP Don Keith Transportation 16 August 14, 1992 * Hands on top of head - need assistance * Thumbs down no, negative. 2. The field engineer or geologist will establish emergency evacuation routes and will make all project personnel aware of these routes prior to the first on-site activities. In the event of an emergency, selection other escape route will be based on the nature of the emergency and wind direction. 3. Visual contact should be maintained between "buddies" on-site, with the team remaining in close proximity in order to assist each other in case of emergencies. 4. In the event that any member of the field crew experiences any adverse effects of symptoms of exposure while on site, the entire field crew should immediately halt work and follow the instructions provided the project supervisor. 5. Wind indicators visible to all on-site personnel should be provided by the project supervisor to indicate possible routes for upwind escape. 6. The discovery of any condition that would suggest the existence of a situation more hazardous than anticipated should result in the evacuation of the field team 'and re-evaluation of the hazard and the level of protection required. 7. In the event an should accident occur, it will be necessary to complete an Accident Report Form with the company Safety Officer. STANDARD SAFE-WORK PRACTICES General I. Eating, drinking, chewing tobacco and smoking are prohibited in the contaminated or potentially contaminated area of where the possibility for the transfer of contamination exists. EB-80228-3 9208-E0328.WP Don Keith Transportation 17 August 14, 1992 2. Avoid contact with potentially contaminated substances. Do not walk through puddles, pools, mud, etc. Avoid, whenever possible, kneeling on the ground, leaning or sitting on equipment or ground. Do not place monitoring equipment on potentially contaminated surfaces (i.e., ground, etc.). 3. All field crew members should be alert to the presence of strong, irritating or nauseating odors that could indicate a potentially dangerous situation. Other senses should be kept alert to possible hazards as well. 4. Precaution should be taken to prevent spillage. In the event a spillage should occur, the liquid should be contained. 5. Prevent splashing of the contaminated liquids. 6. Field crew members shall be familiar with the physical characteristics of investigations, including the following: * Wind direction in relation to ground-zero area. * Accessibility. to associates, equipment, and vehicles. * Communications. * Hot Zone (areas of known or suspected contamination). * Site access. * Nearest water sources. 7.

(ESE) at the above referenced site. The purpose of the characterization was to assess the potential for petroleum impacted soil at two locations on the subject property as part of a baseline environmental assessment performed in conjunction with the marketing of the rea/ parking area at Don Kieth's Asphalt and Diesel Transportation Company. The first area is that of a very large, two stage, earthen bottom clarifier system which formerly served the truck wash for the crude oil, asPhalt, fuel oil and diesel fuel trucking firm. The clarifiers have been backfilled and no surface evidence remains. The property owner has provided a description of the size of each clarifier, and flagged their boundaries. The second area consists of two disposal pits in the rear of the property which received tanker truck bottoms. The surface of these has been covered with soil, however stained soil is visable at the surface in the location of the two pits. ESE has conducted an initial site characterization consisting of eleven soil borings and laboratory analysis of 27 soil samples to evaluate the extent of petroleum hydrocarbons impacted soil in the vicinity of both the former truck wash earthen clarifiers and tank bottom disposal pits. Don Kieth Transportation 2 August 12, 1992 All methods to be employed are in compliance with regulations and guidelines set forth in California Code of Regulations (CCR) Title 22, Article 11, and Title 23, Chapter 3, California Site Mitigation Decision Tree Manual, the' Code of Federal Regulations (CFR) Title 29, Part 1910, Section 120, CFR Title 40, Parts 300-39, and Kern County regulations as well as accepted professional environmental/geotechnical engineering procedures. The scope of work for this project was developed in conjunction with Mr. Chris DeArmon of KES and Mr. James Hubbard of Hubbard Environmental, Inc. (HEI) representing Don Kieth Transportation. In addition, remedial action alternatives are presented. Work performed to date includes the following: · Development of site health and safety plan. · Drilling and sampling of eleven exploratory soil borings to a maximum depth of 48.5 feet below surface grade. · Laboratory analysis of twenty-seven soil samples for Total Recoverable Petroleum Hydrocarbons (TRPH) as oil and grease, seven samples for California Title 22 metals, six samples for volatile and semi-volatile · organics, five samples for Total Extractable Petroleum Hydrocarbons as diesel (TEPHd), and four soil samples for total lead. These samples included a sample of the tank bottom pit sludge which was also analyzed for fuel constituent volatile aromatics and pH. · Preparation of this report presenting our results, conclusions, and remedial action alternatives for the site. 1.1 Site Description. The site is located at 2990 Pierce Road in the city of Bakersfield in Kern County, California (Figure l). The site is currently used as a parking area where the tanker trucks are parked. The site is situated within a developed industrial area. Nearby surrounding properties are primarily retail businesses, petroleum service companies, refineries, and actual oil producing properties. The overall site topography is essentially flat, with a very slight fall to the west. - -- EB-8228-1 9207-E081.RPT Don Kieth Transportation 3 August 12, 1992 1.2 Background Based on conversations with Chris DeArmon, two locations on the subject property had a potential for subsurface soil impacted with petroleum hydrocarbons and required assessment as part of a baseline environmental assessment at Don Kieth's Asphalt and Diesel Transportation Company. The first area is that of a very large, two stage, earthen bottom clarifier system which formerly served the truck wash for the crude oil, asphalt, fuel oil and diesel fuel trucking firm. The clarifiers have been backfilled and no surface evidence remains. The property owner has provided a description of the size of each clarifier, and flagged their boundaries. The second area consists of two disposal pits in the rear of the property which received tanker truck bottoms. The surface of these has been covered with soil, however stained soil is visable at the surface in the location of the two pits. ESE has conducted an initial site characterization consisting of eleven soil borings and laboratory analysis of 27 soil samples to evaluate the extent of petroleum hydrocarbons impacted soil in the 'vicinity of both the former truck wash earthen clarifiers and tank bottom disposal pits. 2.0 METHODS OF INVESTIGATION 2.1 Drilling and Soil Sampling Drilling of four initial borings was conducted on July 13, 1992 using a CMETM 55 truck mounted drill rig, operated by Earth Systems Consultants, and equipped with 6-inch diameter hollow-stem augers. Drilling of seven additional borings to more fully assess the vertical and lateral extent of the impacted soils was conducted on August 6, 1992 using a MobileTM B-53 truck mounted drill rig, operated by Melton Drilling, and equipped with 6-inch diameter hollow-stem augers. The augers were steam cleaned prior to use to minimize the possibility of cross-contamination. Prior to commencing field operations, UndergroUnd Service Alert was notified 48 hours in advance of the site activities. A total of eleven soil borings were drilled within this phase of soil characterization (Figure 2). One soil boring, TH-1 was drilled on July 13, 1992 through the center of the western of the two former truck wash clarifiers location to a depth of 31 feet below surface grade to assess the potential for petroleum hydrocarbons in the · - EB-8228-1 9207-E081.RPT Don Kieth Transportation 4 August 12, 1992 subsurface at that location. On August 6, 1992 this boring was twinned by boring TH-IA which was advanced to a depth of 46 feet to assess the vertical limit of the petroleum hydrocarbons encountered in boring TH-I. A soil boring, TH-2 was drilled on July 13, 1992 through the center of the eastern of the two former clarifiers to a depth of 36 feet below surface grade to assess the potential for petroleum hydrocarbons at that location. On August 6, 1992 this boring was twinned by boring TH-2A which was advanced to a depth of 48.5 feet to assess the vertical limit of the petroleUm hydrocarbons encountered in boring TH-2. Soil borings TH-3A, TH-4 and TH-4A were advanced around the periphery of the two earthen clarifiers to assess the lateral limits of the petroleum hydrocarbons encountered in borings TH-I and TH-2. Soil boring TH-3A was drilled drilled 35 feet southeast of TH-2 outside of the former eastern clarifier location to a depth of 29 feet to assess the the potential for lateral migration of petroleum hydrocarbons in that direction. Soil boring TH-4 was drilled drilled 20 feet north of TH-2 to a depth of 26 feet to assess the the potential for lateral migration of petroleum hydrocarbons in that direction. Soil boring TH-4A was drilled drilled 35 feet southwest of TH-1 to a depth of 35 feet to assess the the potential for lateral migration of petroleum hydrocarbons in that direction. A soil boring, NP was drilled through the center of the northern tank bottom disposal pit location to a depth of 27 feet below surface grade to assess vertical migration of petroleum hydrocarbons at that location. Soil boring TH-3 was drilled drilled 25 feet northeast of NP to a depth of 31 feet to assess the the-potential for lateral migration of petroleum hydrocarbons in that direction. A soil boring, SP was drilled through the center of the southern tank bottom disposal pit location to a depth of 36 feet below surface grade to assess vertical migration of petroleum hydrocarbons at that location. Soil .boring SPL was drilled drilled 35 feet east of SP to a depth of 21 feet to assess the the potential tbr lateral migration of petroleum hydrocarbons in that direction. To better define the limits of the two tank bottoms disposal pits a backhoe operated by Kern Environmental Service was used to excavate five foot deep trenches in the rear portion of the property. Upon exposing the limits of the pits a composite soil sample was collected from the sludge within the two pits at a depth of three feet below surface grade. EB-8228-1 9207-E08 I.RPT Don Kieth Transportation 5 AUgust 12, 1992 Soil samples in the eleven borings were collected at five foot intervals of depth beginning at five feet below surface grade. S0il sampling was accomplished using a split-spoon sampler (ASTM D 3550 with shoe similar to ASTM D 1586) equipped with three 6-inch by 2.5-inch diameter stainless steel sleeves for soil retention. The soil samples were obtained by driving the sampler with a one hundred and forty pound hammer dropping thirty inches in accordance with ASTM D 1586. The lowermost sleeve at each sample interval (corresponding to approximately 18 inches below the actual sample interval) was screened for total organic vapors with a portable 'photoionization detector (PID). Headspace vapor analysis was performed by first discarding a portion of the soil retained at one end of the sleeve to produce a headspace. The sleeve was then capped and the probe of the PID protruded through a hole in the cap and into the headspace for analysis. The PID readings were recorded on the boring logs. The lowermost and uppermost sleeves were then be observed for lithology. The middle sample sleeve was immediately sealed with Teflon® film, capped, security taped, labeled, and placed on ice for transportation to a California Department of Health Services (DOHS) certified laboratory. Strict chain of custody procedures were utilized for all samples collected to ensure sample integrity and to document sample possession from the time of collection to the final destination. The soil samples selected for laboratory analysis included the sample from each boring which was field screened as having the highest concentration of volatile hydrocarbons, and the sample in a "clean" soil boring from the appropriate depth to verify that no hydrocarbons were present. All sampling equipment was washed with TSP (tri-sodium phosphate) cleanser, and rinsed with tap water and de-ionized water prior to sampling, between sample intervals, and between borings to minimize the possibility of cross-contamination. The drill auger was steam cleaned between borings, also to minimize the possibility of cross-contamination. Drill cuttings and soil sample spoils were added to a soil/tank bottoms stockpile which is present along the northern property line as shown in Figure 2. EB-8228-1 9207-E081 .RPT Don Kicth Transportation 6 August 12, 1992 · An environmental geologist under the direct Supervision of a California Registered Geologist was on site to log the borings, monitor soils during drilling for contamination, and collect soil samples. Boring logs are presented in Appendix A. 2.2 Laboratory Analysis Twenty-six soil samples and one sludge sample were submitted to B. C. Laboratories of Bakersfield, Califorinia tbr analysis. All twenty-seven samples were analyzed for Total Recoverable Petroleum Hydrocarbons (TRPH) as oil and grease using USEPA Test Method 418.1. Seven of the samples including the tank bottoms sludge were analyzed for California Title 22 metals. Six of the samples including four t¥om the area of the earthen clarifiers, and two from the area of the tank bottoms disposal pits were analyzed for Volatile and semi-volatile organics using USEPA Test Methods 8240 and 8270. Five samples including the sludge were analyzed for Total Extractable Petroleum Hydrocarbons as diesel (TEPHd) using the DOHS LUFT Manual Method. Four deeper soil samples beneath the earthen clarifiers were analyzed for total lead using the DOHS LUFT Manual Method. The tank bottom pit sludge was also analyzed for fuel constituent volatile aromatics using USEPA Test Method 8020, and for pH. 3.0 RESULTS OF ENVIRONMENTAL ASSESSMENT 3.1 Geologic Conditions Regional Geology: The site is located in the southern part of the Great Valley geomorphic province. The Great Valley is a north-south trending valley, approximately 400 miles long by 50 miles wide. Surface and groundwater in the San Joaquin Valley is derived predominantly from the Sierra Nevada mountain range to the east, and is transported by five major rivers, the southern most being the Kern River. The subject site is located approximately I/2 mile northwest of the Kern River. - ' EB-8228-1 9207-E081 .RPT Don Kieth Transportation 7 August 12, 1992 The surface of the San Joaquin Valley is composed primarily of Unconsolidated Pleistocene (1.6 million to 11,000 years ago) and Recent (11,000 years ago to the present) alluvial sediments. Beneath the alluvial sediments are older, predominantly lake bed deposits. These lie unconformably on Mio-Pliocene marine sediments which extend to crystalline basement at approximately 20,000 feet. Site Geology: Geologic deposits in the study area include Pleistocene alluvial sediments of the Kern River Formation, which form a homocline dipping gently to the west. The deposits are alluvium consisting of poorly indurated and dissected fan deposits (CDMG, 1964). The depth to the regional unconfined aquifer was estimated prior to drilling to be aPproximately 50 feet below surface grade beneath the site (Kern County Water Agency, Improvement District No. 4, 1991 Report on Water Conditions, February 1992). Groundwater was not encountered in boring TH-2A which penetrated to a depth of 48.5 feet. The deepest samples in the borings were moist, 'but did not have an indication that the capillary fringe to groundwater was at that depth. Because of the six consecutive years of drought, and the discontinuance by the Kern County Water Agency of using several large water recharge percolation ponds 1/2 mile to the north, a drop in the elevation of groundwater by as much as 25 feet may have occurred in the area. The nearest known occurrence of perched groundwater is 8 miles to the southeast at a depth of 20 feet in the abandoned Kern River channel to the ancient Kern Lake Bed (Kern County Water Agency, 1991 Water Supply Report, May 1992). No perched groundwater is known to exist beneath the subject site. 3.2 Subsurface Conditions Subsurface material encountered during drilling was alluvium to the total depth of each boring. The alluvium was characterized by unconsolidated, highly permeable, light brown, silty sand (SM) to a depth of approximately 7 feet, overlying unconsolidated, highly permeable, tan, well graded fine- to coarse- grained sand (SW) to a depth of approximately 23 feet. This is underlain by a sequence of unconsolidated, highly permeable, light tan, fine- to coarse- grained gravelly sand (SW/GW) to a depth of 38. Beneath this is a sequence of unconsolidated, highly ~ - EB-8228-1 9207-E081 .RPT Don Kieth Transportation 8 August 12, 1992 permeable, light tan, fine- to coarse- grained sand (SW) to a depth of 43, overlying unconsolidated, highly permeable, light tan, well graded fine- to coarse- grained moderately silty sand (SW/SM) to a depth of approximately 46 feet. This is underlain by a sequence of consolidated, .moderate to Iow permeability, light tan, very clayey silt (MI_JCL) to a depth of 48.5 which was the greatest depth investigated. 3.3 Hydrogeology Groundwater was not encountered in any of the borings drilled during this project. However, the depth to the regional unconfined aquifer was estimated prior to drilling to be approximately 50 feet below surface grade beneath the site (Kern County Water Agency, Improvement District No. 4, 1991 Report on Water Conditions, February 1992). Groundwater was not encountered in boring TH-2A which penetrated to a depth of 48.5 feet. 'The deepest samples in the borings were moist, but did not have an indication that the capillary fringe to groundwater was at that depth. Because of the six consecutive years of drought, and the discontinuance by the Kern County Water Agency of using several large water recharge percolation ponds 1/2 mile to the north, a drop in the elevation of groundwater by as much as 25 feet may have occurred in the area. The nearest known occurrence of perched groundwater is 8 miles to the southeast at a depth of 20 feet in the abandoned Kern River channel to the ancient Kern Lake Bed (Kern County Water Agency, 1991 Water Supply Report, May 1992). No perched groundwater is known to exist beneath the subject site. 3.4 Soil Vapor Monitoring Soil samples collected during drilling were monitored with a photo-ionization detector (PID) to evaluate organic vapor concentrations. The PID was calibrated with an isobutylene standard of 100 parts per million (ppm) and contained an 11.8 electron volt (eV) lamp, capable of detecting benzene (9.25 eV). Table 1- Soil Organic Vapor Concentrations, graphically, presents the PID readings. Appendix A - Boring Logs, presents the PID readings as they were recorded in the field.

As Table I indicates, significant soil vapor concentrations were detected in the soil samples obtained from below the former truck wash clarifiers to a depth of less than 20 feet, and beneath the tbrmer tank bottoms pits to a depth of less than 10 feet. These field'readings are collaborated by the analytical results presented below. 3.5 Laboratory Analytical Results Total Recoverable Petroleum Hydrocarbons (TRPH) as oil and grease were detected at a concentration of 7,900 mg/kg at 10 feet in boring TH-1 advanced through the center of the western clarifier location, but not at 20, 30, 40 and 45 feet in boring TH-lA advanced in the same location. TRPH was detected at a concentration of 10,000 mg/kg at 10 feet in boring TH-2 advanced through the center of the eastern clarifier location and 40 mg/kg at 20 feet in boring TH-2A, but not at 40 and 47 feet in boring T/q-2A. TRPH was not detected at depths of 15 and 25 feet in boring TH-3A advanced 35 feet southeast of TH-2 on the outside of the former clarifier location, or at depths of - EB-8228-1 9207-E081 .RPT Don Kieth Transportation 10 August 12, 1992 10 and 20 feet in boring TH-4 advanced 20 feet north of TH-2, or at depths of i0 and 25 feet in boring TH-4A advanced 35 feet southwest of TH-I. However, TRPH was detected at 20 mg/kg at a depth of 35 feet in boring TH-4A. Total Extractable Petroleum Hydrocarbons as diesel (TEPHd) were analyzed for in the soil samples at 20 feet in borings TH-lA and TH-2A at concentrations of 19 mg/kg, and 23 mg/kg, respectively. The fuel constituent volatile aromatics m- and p-xylenes were detected at a concentration of 0.006 rog/kg at 10 feet in boring TH-1. The fuel constituent volatile aromatics toluene was detected at a concentration of 0.022 rog/kg at 10 feet in boring TH-2. No other volatile organic hydrocarbons including those which constitute fuels and. industrial solvents were detected at or above the minimum detection limit in the four soil samples collected from the clarifier area. No semi-volatile organic hydrocarbons (base neutral and acid extractables) were detected at or above the minimum detection limit in the tour soil samples collected from the clarifier area. Lead was detected at an elevated concentration in one of eight samples from the clarifier area. Total lead was detected at a concentration of 27 mg/kg at a depth of 10 feet in boring TH-2 advanced through the center of the Yastern clarifier, but was not detected in boring.TH-2A at 20 and 40 feet, at 10 and 20 feet in boring TH-4 position 20. feet north of TH-2, and at 10 feet in boring TH~"I or 20 feet in boring TH-IA both located in the center of the western clarifier. Total lead was detected at 2.7 mg/kg at 20 feet in boring TH-lA. The State of California Title 22 Total Threshold Limit Concentration (TTLC) for lead is 1,000 mglkg. However, the. Soluble Threshold Limit Concentration (STLC) for soluble lead is 5 mg/kg. Because of the 10:1 dilution that occurs during the wet extraction any total concentration less than 50 rog/kg will necessarily be determined to have a soluble component less than the STLC of 5 mg/kg. Therefore, a soluble lead wet extract was not performed on the sample in this investigation with a concentration of total lead detected of 27 mg/kg. · - EB-8228- i 9207-E081.RPT Don Kieth Transportation 1 1 August 12, 1992 Arsenic, barium, chromium, cobalt, copper, nickel, vanadium, and zinc were detected in the four soil samples from the clarifier area at concentrations typical of the background concentrations for these metals in the soil in the area of the subject property. The other Title 22 metals were not detected in the four soil samples from the clarifier area. Total Recoverable Petroleum Hydrocarbons (TRPH) as oil and grease was detected at a concentration of 45,000 mg/kg is the composite sample of the sludge from at depth of three feet within the tank bottoms disposal pits. Total Extractable Petroleum Hydrocarbons as diesel (TEPHd) was detected at a concentration of 12,000 mg/kg in this sample. The fuel constituent volatile aromatics benzene, toluene, ethylbenzene, and total xylenes were detected at concentrations of 0.013 rog/kg, 0.038 mg/kg, 0.021 mg/kg, and 0.177 mg/kg, respectively. The pH of the sludge was measured at 7.17. TRPH was not detected in the north pit vertical assessing boring NP at depths of 10, 20 and 25 feet, and in the north pit lateral boring TH-3 at 15 and 25 feet. TRPH was detected in the south pit vertical assessing boring SP at 10 feet at a concentration of 20 mg/kg and 25 feet at a concentration of 60 mg/kg and in the south pit lateral. boring SPL at 10 feet at a concentration of 160 mg/kg, but not in 'vertical assessing boring SP at a depth of 35 feet, or in the south pit lateral boring SPL at 20 feet. The semi-volatile organic hydrocarbon diethyl phthalate was detected at a concentration of 0.1 mg/kg at 15 feet in boring TH-3 advanced adjacent to the northern tank bottoms disposal pit. No other volatile organic hydrocarbons, or semi- volatile organic hydrocarbons were detected at or above the minimum detection limit in the two samples' collected from the area of the tank bottoms disposal pits. Lead was detected at an elevated concentration in the sample of the sludge from the disposal pits. Total lead was detected at a concentration of 44 mg/kg. The State of California Title 22 TTLC for lead is 1,000 mg/kg. However, the STLC for soluble lead is 5 mg/kg. Because of the 10:1 dilution that occurs during the wet extraction any total concentration less than 50 mg/kg will necessarily be determined to have a soluble component le~s than the STLC of 5 mg/kg. Therefore, a soluble lead wet extract was not performed on the sludge sample. Cadmium was detected at 1.2 mg/kg in the EB-8228-1 9207-E081.RPT Don Kieth Transportation 12 August t2, 1992 Cadmium's TTLC is 100 mg/kg, and STLC is 1 mg/kg. Copper was detected at 66 mg/kg in the sludge. Copper's TTLC is 2,500 mg/kg, and STLC is 25 mg/kg. Mercury. was detected at 0.39. mg/kg in the sludge. Mercury's TTLC is 20 mg/kg, and STLC is 0.2 mg/kg. Nickel was detected at 61 mg/kg in the sludge. Nickel's TTLC is 2,000 mg/kg, and STLC is 20 mg/kg. Vanadium was detected at 87 mg/kg in the sludge. Vanadium's TTLC is 2,400 mg/kg, and STLC is 24 mg/kg. Each of these concentrations are far below their respective regulatory limits. Therefore, the sludge is not classified as a. hazardous material by RCRA and California Title 22 criteria. However, these concentrations are in excess of that which occurs in the native soil and indicates an accumulation t¥om the petroleum products. There may be a minor amount of mobility for these metals from the sludge into the underlying soil, however this has not been observed in the investigation. The Regional Water Quality Control Board provides recommended guidelines for TRPH as oil and grease, TEPH as diesel, the fuel constituent volatile aromatics, benzene, toluene? ethylbenzene and total xylenes, and the semi-volatile organic hydrocarbon diethyl phthalate using the LUFT methodology by multiplying the most stringent current federal or state water quality standards by a factor of 100 to account for attenuation due to site-specific parameters including vertical separation to ground water, soil lithology, fractures in subsurfaces, annual average precipitation, and any' direct conduits to groundwater. These recommended guidelines are 1,000 mg/kg for TRPH as oil and grease, 100 mg/kg for TEPH as diesel, 0.3 mg/kg for benzene, 1.0 mg/kg for toluene, 4.0 mg/kg for ethylbenzene, 3.0 mg/kg for total xylenes, and 50 mg/kg for diethyl phthalate. Laboratory analytical results for the twenty seven' soil samples t¥om the eleven soil borings, are summarized in Table 2 - Summary of Analytical Results.

EB-8228-1 9207-E081 .RPT Don Kieth Transportation 14 August 12, 1992 4.0 CONCLUSIONS The data obtained suggest that soil impacted beneath the former location of the truck wash earthen clarifiers has been impacted by petroleum hydrocarbons at concentrations in excess RWQCB recommended guidelines to a depth of less than 20 feet below surface. The data does not indicate that fuel constituents, solvents, or heavy metals have impacted this 'soil. ESE concludes that the petroleum hydrocarbons detected represent heavier molecular weight crude oil and refined products devoid of known hazardous constituents. The lateral extent of this impacted soil does not extend laterally from the boundaries of the former clarifiers. Therefore, ESE estimates that the soil between the base of the former clarifiers at a depth of 8 feet to a depth of 18 feet has concentrations of TRPH as oil in grease in excess of the recommended guidelines over an area 75 feet long by 40 feet wide for a volume of impacted soil of approximately 1,000 cubic yards. It is ESE's oppinion that excavation of the soil to these dimensions will removal all of the impacted, soil with concentrations of TRPH as oil and grease in excess of 100 mg/kg. The operation of the tank bottoms disposal pits appears to have impacted the soil to a depth of less than 5 feet at the location of the pits. The data does not indicate that fuel constituents, solvents, or heavy have impacted this soil. However, the sludge does contain slightly elevated concentrations of heavy metals, but remains classified as non-hazardous by RCRA and California Title '22 criteria. ESE concludes that the petroleum hydrocarbons detected represent heavier molecular weight crude oil and refined products. The lateral extent of this impacted soil does not extend laterally from the boundaries of the disposal pits. Therefore, ESE estimates that the soil within the northern pit to a depth of 5 feet has concentrations of TRPH as oil in grease in eXcess of the recommended guidelines over an area 30 feet long by 25 feet wide for a volume of impacted soil of approximately 14(} cubic yards, and soil within the southern pit to a depth of 5 feet over an area 55 feet long by 15 feet wide for a volume of approximately 150 cubic yards. It is ESE's oppinion that excavation of the soil to these dimensions will removal all of the impacted soil with concentrations of TRPH as oil and grease in excess of 100 rog/kg. EB-8228-1 9207-E081 .RPT Don Kieth Transportation 15 August 12, 1992 5.0 RECOMMENDATIONS ESE recommends excavation and surface bioremediation of the soil beneath the former clarifiers, and excavation and off-site disposal of the sludge from the disposal pits. The impacted soil from beneath the former clarifiers should be excavated to a depth 18 feet and treating the soil to concentrations less than the RWQCB recommended guidelines through the process of bioremediation at the subject property. Surface bioremediation has been shown to be particularly successful in the San Joaquin Valley given the high temperature, and low relative humidity. This option is particularly viable at this site since the facility has available land to treat the soil. The impacted soil beneath the former clarifiers will respond very well to surface bioremediation. Because the property is in a commercial/petroleum setting, there is only a slight risk of exposure of any off site population to volatilized petroleum hydrocarbons, and therefore very little health risk to the general' public associated with the treatment. This option can be particularly attractive since on site treatment alleviates the clients future liability for the soil. On-site treatment is not recommended for the sludge from the disposal pits because it will require an inordinate amount of time and effort for bioremediation to reduce the concentrations to below the RWQCB recommended guidelines. The impacted soil from beneath the former disposal pits should be excavated to a depth of 5 feet where the site assessment indicates that the limits of concentrations in excess of'the RWQCB recommended guidelines will have been reached. Selection of an appropriate recycling or disposal facility depends on the concentration of contaminants in the soil after it is stockpiled. Judging from the findings of this study, it appears likely that the semi-solid/semi-liquid state of the sludge from the disposal pits makes that material unacceptable to solid waste recycling facilities. It is ESE,s opinion that the appropriate classification for this material is as a designated petroleum waste, and that the sludge materials may be disposed of as non-hazardous at a petroleum waste landfill such as the McKittrick disposal facility. EB-8228-1 9207-E081.RPT Don Kieth Transportation 16 August 12, 1992 6.0 CLOSURE This report has been prepared for the exclusive use of KES, HEI, and Don Kieth Transportation'as it pertains to the location of the former truck wash earthen clarifiers, and tank bottoms disposal pits at 2990 Pierce Road, Bakersfield, California. The results contained in each verbal or written report are based upon the information acquired during the assessment. It is possible that variations could exist beyond points explored during the course of the investigation. Also, changes in conditions found could occur at some time in the future due to contaminant migration, variations in rainfall, temperature, and/or other factors not apparent at the time of the field investigation. This report should not be regarded as a guarantee that no further contamination, beyond that which may have been detected within the scope of this study, is present on or beneath the site. If additional information regarding the possible presence or past use of hazardous materials at the site becomes available, then the need for further field investigation should be re- evaluated. Similarly, if suspected contamination is encountered during earthwork or construction activities, a qualified engineer or geologist should be on-site to monitor the soils and collect, samples for laboratory analysis. The services performed by ESE were conducted in a manner consistent with the level of care and skill ordinarily exercised by members of our profession currently practicing under similar conditions in the state of California. No other warranty is expressed or implied. Thank you for this opportunity to be of service.
