Box 5337 Bakersfield, California 93388 Attention: Mr. Chris DeArmon SUBJECT: PRELIMINARY SITE CHARACTERIZATION OF PETROLEUM IMPACTED SOILS DON KIETH TRANSPORTATION 2990 PIERCE ROAD BAKERSFIELD, CALIFORNIA 1.0 INTRODUCTION This report presents the results of a preliminary site characterization performed by Earth Systems Environmental, Inc. (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 rear 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 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. 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 f'trm. The clarifiers have been baekfilled 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 Transportatioff 4 August 12, 1992 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-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 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. EB-8228-I 9207-E081.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. Soil 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-E08 I.RPT Don Kieth 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 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. 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 1/2 mile northwest of the Kern River. EB-8228-1 9207-E08 i.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-E08 I.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 low permeability, light tan, very clayey silt (ML/CL) 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 l~lonitoring 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.

NR: No Recovery. As Table 1 indicates, significant soil vapor concentrations were detected in the soil samples obtained t¥om below the former truck wash clarifiers to a depth of less than 20 feet, and beneath the former 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 rog/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 rog/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 TI-I-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 TI-I-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 mg/kg at 10 feet in boring TH-1. 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 I0 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 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 mg/kg. 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 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 mg/kg. EB-8228-1 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 rog/kg, and 0.177 rog/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 rog/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 rog/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 -8228-1 . 9207-E081 .RPT Don Kieth Transportatio~ 1 2 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 rog/kg. Mercury was detected at 0.39 rog/kg in the sludge. Mercury's TTLC is 20 mg/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 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 product's. 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 from the eleven soil borings are summarized in Table 2 Summary of Analytical Results. Copies of the analytical reports and chain of custody documentation are presented in Appendix B - Laboratory 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 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- I 9207-E081 .RPT Don Kieth Transportation 15 August 12, 1992 5.0 RECOMMENDATIONS ESE recommends excavation and surface bioremediation of the soil beneath 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 stockpiIed. 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 MeKittrick 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 tbr 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.
