Don Keith Transportation 2 January 29, 1993 These activities include the excavation and bioremediation of 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 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 baekfilled 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 hydr6earbons as diesel were less than 100 mg/kg. ESE recommends that the treated soil be used as grading fill material on site. EB-8228-3 9301-5030.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 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 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 cominued 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 rog/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 rog/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.

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 fiat, 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 etude oil, asphalt, fuel oil and diesel fuel trucking firm. The elarifiers 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 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 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 7 january 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 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 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 9301-5030.RPT Don Keith Transportation 8 January 29, 1993 · 0 2.2.2Re~jlts 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'l 1,000 years ago) and Recent (I1,000 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 1t2 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 low 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 rog/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-IA 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 elarifier location and 40 rog/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 I0 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 0 The fuel constituent volatile aromatics m- and p-xylenes were detected at a concentration of 0.006 rog/kg at I0 feet in boring TH-I. The fuel constituent volatile -- aromatics toluene was detected at a concentration of 0.022 mg/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 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 elarifier, 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 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 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 rog/kg. Arsenic, barium, chromium, cobalt, copper, nickel, vanadium, and zinc were detected in the four soil samples from the elarifier 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. "- E1~-8228-3 9301-5030.RPT . Don Keith Transportation 1 1 January 29, 1993 Total Recoverable Petroleum Hydrocarbons (TRPH) as oil and grease was .detected at a concentration of 45,000 rog/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 rog/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 rog/kg and 25 feet at a concentration of 60 mg/kg and in the south pit lateral boring SPL at I0 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 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. -'- EB-8228-3 9301-$030.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 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 rog/kg in the -- sludge. Mercury's 'I'FLC 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 rog/kg, and STLC is 20 mg/kg. Vanadium was detected at 8'/ 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 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 mg/kg for benzene, 1.0 rog/kg for toluene, 4.0 mg/kg for ethylbenzene, 3.0 mg/kg for total xylenes, and 50 mg/kg for diethyl phthalate.

'- EB-8228-3 9301-5030.RPT Don Keith Transportation 14 January 29, 1993 0 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 ii 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 ali of the impacted soil with concentrations of TRPH as oil and grease in excess of 100 me/kg. EB-8228-3 9301-5030.RPT Don Keith Transportation 15 January 29, 1993 2.2.4 R~comm~ndations from the Subsurface Investigation ESE recommended excavation and surface bioremediation of the soil beneath the -- former clarifiers, 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 t6 January 29, 1993 2.2.5 S0il Excavation Kern Environmental Services provided fr°nt 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 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 (Cal 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 swekpiles. 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 Reelaimer 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 front 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 January 29, 1993 - north to south at the two southwestern clarifiers, and to a depth of 23 feet below surface grade °ver 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. Exeavatio~t Pit Fi~.l~l 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 KCDEI-IS representative from the boundaries of the excavations to verify satisfactory removal of the impacted soil. Soil Sample (~o!l.ection 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 ttmck 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 9301-5030.RPT Don Keith Transportation 18 January 29, I993 0 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. l_~boratory 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. Anlllytic~l 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 rog/kg, and 700 rog/kg. This corner was subsequently excavated when the northeastern elarifier was removed. Four of the five soil samples collected from the northeastern truck wash elarifier excavation were non detected for TRPH as oil and grease. One of the soil samples from the northeastern elarifier detected TRPH as oil and grease at a concentration of 20 mg/kg.

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:f06, 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 2 1 January 29, 1993 0 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 Boreas 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 stockpiled 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 $). 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. - ' EB-8228-3 9301-5030.RPT Don Keith Transportation 22 January 29, 1993 5.0 LABORATORY ANALYSIS OF TREATED SOIL The two September 23, 1992 soil samples were analyzed at BC Laboratories, a State of California certified laboratory for total recoverable petroleum hydrocarbons (TRPH) as oil and grease by USEPA Test Method 418.1, and total extractable petroleum hydrocarbons as diesel (TEPHd) by USEPA Test Method 8015 (modified for diesel).

In the second sample, TRPH as oil and grease was 380 mg/kg while TEPH as diesel was 200 mg/kg. Therefore, diesel hydrocarbons appeared to represent 60% of the total petroleum hydrocarbons. .... EB-8225-3 9301-5030.RPT Don Keith TranSpo~ation 23 January 29, 1993 0 . In the October I, 1992 sampling event, TRPH as oil and grease were detected in similar locations at 1,900 mg/kg and 500 rog/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, TEPH as diesel was detected at concentrations ranging from 100 mg/kg to 1,200 mg/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 TEPH as diesel at 1,100 mg/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 mg/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 fou~ sampling events (i.e. the southwest extension had TEPH as diesel at 200 mg/kg on September 23, 1992, TRPH as oil and grease at 500 mg/kg on October 1, 1992, TEPH as diesel at 400 rog/kg on October 23, 1992, and TEPH as diesel at 300 mg/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 0 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 8, 1993 samples were analyzed for a fuel fingerprint. The results eonfh'med 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 from 1,300 mg/kg to 2,000 mg/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 I5 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 ehromatogram 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.' Smart Butlxam 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.
