During soft sampling for laboratory analysis of TPH, retrieved at a depth of 27 feet below surface grade (BSG) at the former dry well, groundwater entered the excavation. Laboratory analyses of the soft retrieved indicates the presence of TPH at 21 ppm. Since groundwater was present during the soft sampling, the issue of groundwater impaction by TPH must be addressed to the satisfaction of this Department and the Environmental Protection Agency (EPA). The Source Water Protection Section of EPA, Region 9, administers the Underground Injection Control (UIC) regulations. The UIC program is designed to protect groundwater from contaminants reaching the subsurface through class 5 disposal wells. In Region 9,' there is an emphasis on class 5 disposal wells because their disposal of fluids Poses a threat to underground sources of drinking water and the public health. The report of remedial action dated June 10, 1994, prepared by Holguind Fahan and Associates, Inc., is incomplete due to the lack of recommendations addressing the above issue. Investigation and remediation of groundwater affected by a release of petroleum hydrocarbons resulting from past use of the former dry well must be accomplished before closure of the site may be considered. Please contact your environmental consultant with directions to initiate groundwater investigation at Central California Kenworth within sixty (60) days of receipt of this notice. A workplan is required for review and approval before any work is started. Failure to comply with this notice will result in a referral of this site to the Environmental Protection Agency for follow-up and enforcement actions.

The excavation uncovered a 14-inch pipe leading from the building to the dry vault. The* residual material in the pipe was sampled for TPH. An inspection of thc building was undertaken to ascertain the origin of the pipe. Thc inspection included the vehicle wash bay, which contained a sump filled with water and an oily residue. The sump water had formerly entered the drainage pipe leading to the clarifiers abandoned by Holquin, Fahan and Associates on August 11, 1993. At the time of the abandonment, the inlet lines discharging wash water to the clarinets were plugged at the point of discharge and the ¢larifiers filled with cement. Prior to the time of the above clarifier abandonment, Central California Kenworth installed a recycling unit in the wash bay after disconnecting and plugging the sump discharge lines. The sump apparently was utilized as a portion of the recycling unit during the remainder of Kenworth's tenancy. The wash bay sump water has not been properly disposed, nor the complete abandonment of thc sump addressed at this time. The sump water must be sampled for TPH and properly disposed. The sump should be steam cleaned and inspected for integrity. If the sump integrity has not been compromised, it may be abandoned by filfiog with cement.

The laboratory report of soil sampled at test holes B-1 and B-3 was not significant; however, test hole B-2 located at the waste oil vault has revealed that a release of petroleum hydrocarbons has occurred to the surrounding soil. No further soil investigation is required at this time. However, remedial activities will be necessary. H.F.A. has recommended excavation at the waste oil vault and disposal of the vault's contents, plus the excavated soil' surrounding the vault, at an approved treatment facility. This office agrees with the proposal. The excavation may be brought to grade using clean fill and compacted after soil sampling has assured that all impacted soil has been removed. It is not clear what function the concrete vault present at test hole B-1 served; however, the report of laboratory analyses of soil sampled during the site investigation reveals no contamination. The concrete vault may either be removed or abandoned in. place by filling with cement sand slurry.

The drilling and soil sampling activities were conducted as the preliminary phase of a site investigation of the potential for hydrocarbon-containing soils two underground concrete waste oil vaults, and a storm water drain at the above referenced site. EXECUTIVE SUMMARY On September 14, 1993, HFA drilled three boreholes adjacent to the waste oil vaults and storm water drain in order to determine the potential for the presence of petroleum hydrocarbons in the soil. Borehole B-1 was drilled adjacent to the west side of the western waste oil vault to a depth of 30 feet below ground level (BGL) (see Figure 2 - Plot Plan). Borehole B-2 was drilled adjacent to the west side of the eastern waste oil vault to a depth of 2,5 feet BGL. Borehole B-3 was drilled through the center of the storm water drain to a depth of 22.5 feet BGL. Hydrocarbon- containing soils were detected in borehole B-2tat a depth of 10 feet BGL. The depth to the regional, unconfined aquifer is approximately 5,.._g feet B~L beneath the site and the groundwater gradient is to the west. However, a~perched"~,g, roundwater zone was observed in Borehole B-1 at 28 feet BGL. Boreholes B-2 and B-3 were terminated above that depth so as to not penetrate this groundwater zone. Based on the findings of this preliminary site assessment, concentrations of total petroleum hydrocarbons (TPH) as oil & grease were detected in the soil beneath the eastern waste oil tank at a depth of 10 feet BGL. This will likely result in the Kern County Resources Management Agency - Department of Environmental Health Services (KCRMA-DEHS) requiring mitigation measures to reduce the concentra'tion of petroleum hydrocarbons in the soil to below the recommended guidelines. SITE DESCRIPTION The site is located at 3012 Pierce Road in the unincorporated area west of the city of Bakersfield in Kern County, California (see Figure I - Site Location Map). The proiect site is bounded on the west by Pierce Road, on the south by Don Keith Trucking Company, on the east by the Office Depot store, and on fhe north by the Home Base store. [he property is currently operating as a large truck and bus maintenance facility, tine topography ot the site is relatively flat, with a slight tall to the west.

The floor drain formerly connected to a pipelir~e which led to four septic tanks in series along the southern property line. On August 25, 1988, representatives of the U. S. Environmental Protection Agency (USEPA) conducted an inspection of the property to determine whether any practices at the property presented a threat to groundwater resources. At that time they noted that the septic tank system connected to the floor drain warranted further investigation as a potential Class V shallow disposal well, Subsequently, the KCRMA-DEHS received funding through the USEPA to conduct a pilot program for local enforcement of Class V shallow disposal wells. On January 8,, 1993 a water sample was collected by KCRMA-DEHS from the septic tanks. The sample was analyzed for Total Petroleum Hydrocarbons as gasoline, diesel and o!1 & grease, volatile organics, and California Title 22 metals. KCRMA-DEHS reviewed the analytical data, and determined that USEPA standards had not been exceeded. Kenworth was instructed to disconnect the piping leading from the floor drain to the septic tanks, and abandon the septic tanks in-place by filling with a cement-sand slurry. Kenworth performed the first task by disconnecting the piping. HFA completed the second task of septic tank abandonment on A~gust 11, 1993. / The septic tanks were abandoned by HFA on August 11, t993 by performing the following tasks: 1) the surface lids of the septic tanks were exposed and removed, 2) a vacuum truck removal any remaining liquid within the septic tanks, 3) a plug was placed in the inlet piping from the floor drain to the first septic tank, 4) the septic tanks were pressure washed to remove any residual substances from the walls of the tanks, 5) the vacuum truck removed the rinsate from the septic tanks, 6) the septic tanks was filled with a five sack cement-sand slurry to within one feet of the top of the necks, 7) a neat cement grout was used to fill the remaining one foot to the top of the tanks with the top surface domed to cause water to flow away from the tanks, and 8) the vacuum truck transported the liquid from the inside the tanks to Gibson Oil and Refining's Bakersfield facility where the liquict will be disposed of. During the septic tank abandonment at the property, the KCRMA-DEHS representative observed the presence of a possible Class V shallow disposal welt approximately 20 feet east of the septic tanks, an underground concrete waste oil vault, and a storm water drain in .the soufheast corner of the property (see Figure 2 - Plot Plan). The KCRMA-DEHS requested in their letter dated August 17, 1993, that a site investigation be performed to assess whether the former operation of lhese features has resulted in a release of hazardous materials to the subsurface. OL©UI Inland Kenworth Bakersfield, California Fz~J-J~i",~ October 11, 1993- Page 3 & IATES. INC. ENVIRONMENTAL M~,N~,GEMI=:NT CONSULT~,NTS SITE GEOLOGY The site is located in a relatively flat area at an elevation of approximately 500 feet above mean sea level. The site is located in the southern part ct the Great Valley geomorphic province. The Great Valley is a north-south trending valley, approximately 400 miles long by ,50 miles wide, the southern portion of which is known as the San Joaquin Valley. The surface ct the San Joaquin Valley is composed primarily ct unconsolidated Pleistocene- age (1.6 million to 11,000 years ago) and Recent-age (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 30,000 feet BGL. Geologic deposits in the study area include Pleistocene-age alluvial sediments of the Kern River Formation, which form a homocline dipping gently to the southwest. The deposits are alluvium consisting of poorly indurated and dissected fan deposits (California Department ct Mines and Geology, 1964). This is an area at the toot ct roiling hills with a maximum elevation of 900 feet MSL, located on the eastern flank of the San Joaquin Valley and west of the southern Sierra Nevada. The Kern River drains a large area of the southern Sierra Nevada, including the highest part of the range at Mount Whitney. The modern river has cut a channel southeast of the site and provides recharge for groundwater along its course. Sedimentary geologic formations, observed at the surface and underlying the site, were sourced by the Sierra Nevada and transported via the ancestral Kern River, In the region of the site, the Tertiary sedimentary sequence, from top to bottom, is nonmarine Kern River Formation, nonmarine Chanac Formation, marine Santa Margarita Formation (possibly intertingerJng with Chanac Formation due to tentative correlation of type Santa Margarita Formation section-west of the San Anareas fault), marine Round Mountain Silt, marine Olcese Sand, marine Freeman Silt, marine Jewett.Sand and Pyramid Hill member, marine Vedder Sand, nonmarJne Walker Formation, Of these, only the Kern River Formation, Chanac, and Santa Margarita are important to the hydrogeology ct the site. The Tertiary nonmarine Kern River Formation is unconformably overlain by bouldery terrace deposits ct Quaternary Older Alluvium. Two naturally occurring geologic units are present in the near surface at the site. The two natural units are the Tertiary (Miocene to Pliocene) nonmarine Kern River Formation, and Quaternary (Pleistocene) Older Alluvium. The Older Alluvium forms a th'in terrace deposit lying unconformably on the Kern River Formation. HOLGUIh Inland. Kenworth Bakersfield, CalifOrnia ~ FAHAN October 11, 1993- Page 4 & A&SOCIATF , INC. ENVIRONMENTAL MANAGEMENT CONSULTANTS Quaternary Older Alluvium is middle lo lower Pleistocene age (Qoa2 of Barrow, 1984). The Older Alluvium is a flat lying terrace deposit approximately 5 feet thick which overlies the erosional surface of the Kern River Formation. The Older Alluvium is comprised of very coarse material, with boulders to 50cm in diameter. Clastic material composition includes granitic and dioritic crystalline rocks characteristic of the Sierra Nevada batholiths, quartzite characteristic of pre-batholithic rocks, and volcanic and related rocks such as andesite and dark siliceous agate typical of Neogene deposits of the Moiave desert. In some locations caliche rims have developed between ctasts; Kern River Formation The age of the Kern River Formation includes upper Miocene and Pliocene, and possibly Pleistocene. The Kern River Formation is comprised of interstratified fanglomeratic deposits and silty claystones. Within the fanglomerates are conglomerate beds with cobbles to 20cra in diameter, and in some areas fanglomerate beds exhibit cross bedding 2.5 to 5 meters thick. The silty claystone beds, which would serve as Iow permeability barriers to vertical migration, are laterally continuous as much as several thousand feet, but are locally truncated by sandy fanglomerate units. Another important factor in considering the potential for migration is the lack of secondary permeability within the Kern River Formation as no secondary cracks, small faults or gypsum veins are observed. Chanac Formation The Chanac Formation of upper Miocene age, is not exposed on or near the site, but outcrops in the cliffs east of the site along the Kern River bluffs at Hart Park. It is a thinly bedded chalky siltstone exhibiting many secondary cracks and gypsum veins. Soil borings advanced by the consultant on an adioining property indicate that the alluvium is characterized by unconsolidated, moderate to g_good permeability silfiy sand to a depth of approximately 7 feet below ground level (BGL), overlying unconsolidated, highly permeable, fine-grained to coarse-.cjrained sand to a depth of approximately 23 feet BGL. Underlying this is a zone of unconsolidated, hi~Jy_, permeable,~to coarse-.qrained sand and gravel to a depth of approximately 38 feet BGL. This is underlain by unconsolic~"a~ed, highly pete, fine-grained to coarse-grained silty sand to a depth of 46 feet BGL. Underlying this is a zone of consolidated, Iow permeability, clayey silt to a depth of 48.5 feet BGL, which was the greatest depth drilling during that investigation. SITE HYDROGEOLOGY 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 southernmost being the Kern River. The subject site is located approximately one half mite north of the Kern River. The depth to th~ region(ti unconfined aquifer is approximately HOLGUIN, Inland Kenworth Bakersfield, California ~ FAHAN October 11. 1993- Page 5 ~ & ~IATES, INC. ENVIRONMENTAL MANAGEMENT CONSULTANTS 50 feet BGL beneath the site with the direction pt groundwater flow to the west-northwest (Kern County Water Agency, 1991 Report on Water Conditions, Improvement District No. 4, February 1992). 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, 199t Water Supply Report, May 1992). SITE EVALUATION METHODS The obiective of this phase of investigation was to assess the potential for hydrocarbon- containing soils associated with two underground waste oil vaults and a storm water drain at the site. A preliminary site assessment work plan to drill boreholes was approved by the KCRMA- DEHS, Borehole B~I was drilled adiacent to the west side of the western waste oil vault to a total depth of 30 feet BGL. Borehole B-2 was drilled adjacent to the west side of the eastern waste oil vault to a total depth of 25 feet BGL. Borehole B-3 was drilled through the storm water drain to a total depth of 22.5 feet BGL. SOILS INVESTIGATION AND SAMPLING RESULTS Prior to conducting the assessment, underground utilities such as water, electrical, and sewer were mapped by USA Underground Alert, The three soil borings were drilled at the site according to the borehote drilling and soil sampling procedures described in Attachment 2. HFA performed the drilling and sampling on September 14, 1993, using a Mobile B-53 drill rig operated by Melton Drilling of Bakersfield, California. Soils encountered while drilling included silty sand to a depth of approximately 7 feet BGL, overlying sandy silt to a depth of approximately 20 feet BGL, which is in turn underlain by coarse-grained sand to a depth of approximately 30 feet BGL which was the greatest depth penetrated during this investigation (see Attachment 3 for soil boring logs). Groundwater was encountered in borehole B-1 at'a depth of 28 feet BGL, Therefore, the other two borings were terminated a'~ove this depth. Undisturbed soil samples were collected at five-foot intervals and selectively tested for a petroleum fingerprint consisting of TPH as gasoline, diesel, motor oil and crude oil, the fuel constituent volatile aromatics benzene, toluene, ethylbenzene and total xylenes (BTEX), and common solvents using EPA Method 8260 as well as one sample from each borehole analyzed for the California Title 22 metals. In addition samples of the li..._~quids and sludge within the eastern waste oil vault were collected on September 17, 1993 and analyzed for TPH as gasoline, diesel, motor oil and crude oil, BTEX and common solvents using EPA Method 8260, TPH as oil and grease by EPA Method 418.1, and the Calitornia Title 22 metals (see Attachment 1, Tables 1.1 and 1.2, for a summary of the laboratory analysis results and Attachment 4 for the current laboratory analysis report). HOLGUINe Inland Kenworth Bakersfield, California FAHAN ~ October 11, 1993- Page 6 &ASSOCIATES, INC. ENVIRONMENTAL MANAGEMENT CONSULTANTS Analysis of soil samples collected from borehole B-2 (advanced adjacent to the west side of the eastern waste oil vault) showed hydrocarbon-containing soils at a depth ot 10 feet BGL as indicated by TPH as kerosene at 410 rog/kg (see Attachment 1, Table 1.1, and Attachments 3 and 4). TPH, BTEX and common solvents were not detected in boreholes B-1 and B-3. The California Title 22 metals were detected at concentrations consistent with native concentrations in the area. ~ ~ r ~, Analysis of liquid and sludge samples col!ected from the eastern waste oil vault showed hydrocarbon-containing liquids as indicated by TPH as oil & grease at 7,400 mg/i (see Attachment 1, Table 1.2, and Attachment 4). TPH as gasoline and diesel, BTEX and common solvents were not detected with the exception of toluene at 0.008 mg/I, 1,2,4-trimethylbenzene at 0.0016 rog/I, and naphthalene at 0.001 mg/I. The California Title 22 metal lead was detected at concentrations of 1,~,,~m_g/k~q for total lead in the sludge, and _2~2 mg/I for soluble lead. Therefore, the waste oil vault contains a liquid which will require disposal at one of several approved recycling facilities. 1~'~ CONCLUSIONS 1, Hydrocarbon-containing soils are detected in the soil adjacent to the eastern waste oil vault at a depth of 10 feet BGL. Hydrocarbon-containing soils were not detected in the soil adjacent to the western waste oil vault or the storm water drain. 2. Based on the findings of this preliminary site assessment, the KCRMA-DEHS may require remedial measures to reduce the concentration of petroleum hydrocarbons within the soil to below recommended guidelines adjacent to the eastern waste oil vault. RECOMMENDATIONS HFA recommends that the two waste oil vaults be abandoned under permit with the KCRMA-DEHS and that the hydrocarbon-containing soils associated with the eastern waste oil vault be excavated and eilher treated on-site through bioremedial technologies, or disposed of off-site at one of several approved road base materials recycling facilities.

BOREHOLE DRILLING AND SOIL SAMPLING PROCEDURES HOLGUI ' ..,,, ' FAHAN :' ?'' ' & ASSOCIATF , INC. ENVIRONMENTAL MANAGI~ME~NT CONSULTANTS BOREHOLE DRILLING AND SOIL SAMPLING PROCEDURES SITING Soil borings were positioned as noted in the report. TRUCK-MOUNTED DRILLING AND SOIL SAMPLING PROCEDURES Each borehole was manually drilled for the first four feet in order to establish that the area was clear of subsurface structures. The borings were drilled with 8-inch outside diameter, hollow-stem, flight augers to the depths noted in the report. During the drilling process, soil cuttings were continuously monitored in conformance with the monitoring procedures, and data was recorded on soil boring logs by an experienced environmental geologist under the direct supervision of a State of California registered geologist. Soil samples were collected with a California split-spoon sampler at intervals consistent with the work plan, unless a change in lithology was noted, in which case an additional samp, le was collected. The sampler was outfitted with 2.5-inch by 6-inch stainless steel or brass sleeves. When the sample was withdrawn, the ends of the sleeve were covered with aluminum foil or TeflonTM tape followed by plastic caps. Sample preservation, handling, and transportation procedures was consistent with HFA's QA/QC procedures. BOREHOLE MONITORING PROCEDURES Cuttings from soil borings were continuously classified according to the Unified Soil Classification System (USCS) and logged by an experienced environmental geologist under the direct supervision of a State of California registered geologist. Specific geologic and hydrologic information that were collected include stratigraphy (i.e., layer thickness, unit correlation, aquifer thickness, depth to groundwater, and confining units, i~ any), relative permeability, observed porosity, plasticity, moisture content, soil type, structure, size, and other features that could affect contaminant transport. Specific geologic and hydrologic information that were obtained during borehole construction includes the following: · stratigraphic characteristics: thickness, correlation of units, extent (horizontal and vertical) of aquifers and confining units, if any; · observed porosity; · volatile organic content; · particle-size distribution; · moisture content; · plasticity; · strength; HOLGUI '- soil Boring Procedures FAHAN Page 2 & ASSOCIATF , INC. ENVIRONMENTAL MANAGEMENT CONSULTANTS · mineral composition; · depth to groundwater; · soil type, structure, size; and · distribution of soil type. The data was recorded on individual soil boring logs, including observations regarding the types and quantities of waste materials encountered and any photoionization detector readings. This data is recorded on a standardized log sheet in the Field Log Book. Specific information that were recorded is listed in Table 1, below. TABLE 1.

ENVI~:::IONMF:NTAL MANAGEMENT OONSULTANTS All field logs were typed and are presented verbatim in an appendix of the preliminary soil assessment report. The typed soil boring logs are on a form identical to that used in the field Icg book. Each soil boring Icg includes a graphic Icg in which a symbol for each USCS soil group is included for each soil interval. DATA REDUCTION The data compiled from the soil borings were summarized and analyzed. A narrative summary of the soil characteristics is also presented. The soil boring logs were checked for the following information: · correlation of stratigraphic units among boreholes; · identification of zones of potentially high hydraulic conductivity; * identification of the confining formation/layer; · indication of unusual/unpredicted geologic features,, (fault zones, fracture traces, facies changes, solution channels, buried stream deposits, cross-cutting structures, pinchout zones, etc.): and · continuity of petrographic features such as sorting, grain-size distribution, cementation, etc. Borehole locations were plotted on a properly scaled map. The purpose of each borehole/piezometer/monitoring well/pit/soil sample is indicated on the map. Depending on the results of this analysis, the soil stratigraphy of the site is presented in a scaled stratigraphic column (if soil stratigraphy is laterally homogeneous) or, more likely, in a scaled cross section or a fence diagram (if soil is laterally heterogeneous). Specific features that may impact contaminant migration, e.g., fault zones or impermeable layers, are discussed in narrative form and supplemented with graphical presentations as deemed appropriate. DECONTAMINATION PROCEDURES Prior to each sampling episode, the sampling equipment was decontaminated using a non-phosphate soap wash, a tap water rinse, and two deionized water rinses. The drill string was decontaminated with a steam cleaner between each well/boring. & TES, INC. ENVIRONMENTAL MANAGEMENT CONSULTANTS BOREHOLE ABANDONMENT The boreholes were abandoned with a 5% bentonite neat cement grout delivered by a grout pump through a tremmie pipe. WASTE MANAGEMENT AND DISPOSAL The cuttings from the boreholes were stored in 55-gallon, Department of Transportation drums. Each drum will be labeled with the date that the waste was generated and the numbers of the soil borings from which the waste was withdrawn. The drums were stored at the site of generation until sample analyses was obtainea. Sample analyses and an inventory of drums was given to Mr Jim Hubbard with Hubbard Enviromanagement, Inc., who will coordinate on-site treatment or proper disposal of the soil, according to Regional Water Quality Control Board requirements. ~ - .

Ms, Flora Darling Kern County Resources Management Agency Department of Environmental Health Services 2700 M Street, Suite 300 Bakersfield, California 93301 SUBJECT: ADDENDUM TO THE WORK PLAN FOR PRELIMINARY SITE ASSESSMENT INLAND KENWORTH, 3012 PIERCE ROAD, BAKERSFIELD, CALIFORNIA Dear Ms. Darling: The following addendum to the site assessment work plan outlines Holguin, Fahan & Associates, Inc.'s (HFA) proposed methodology for the preliminary assessment of possible hydrocarbon-containing soils associated with the former operation of a USEPA Class V shallow disposal well, an underground concrete waste oil vault, and a storm water drain at the above referenced site. HFA proposes to advance three boreholes to a depth of 30 feet below ground level (BGL) and analyze six soil samples for the presence of total petroleum hydrocarbons (TPH), the volatile aromatics benzene, toluene, ethylbenzene, and total xylenes (BTEX), and halogenated hydrocarbons (solvents), as well as one sample from each boring analyzed for the California Title 22 Metals. The additional assessment activities to the original work plan is the third soil boring adjacent to the storm water drain. 1. SITE INFORMATION: Background information about the site is described below. Site Description The site is located at 3012 Pierce Road in the unincorporated area west of the city of Bakersfield in Kern County, California (see Figure 1 - Site Location Map). The project site is bounded on the west by Pierce Road, on the south by Don Keith Trucking Company, on the east by the Office Depot store, and on the north by the Home Base store. The property is currently operating as a large truck and bus maintenance facility. The topography of the site is relatively flat, with a slight fall to the west. Site History During the septic tank abandonment at the property, lhe Kern County Resources Management Agency - Department of Environmental Health Services (KCRMA-DEHS) representative observed the presence of a possible Class V shallow disposal well approximately 20 feet east of the septic tanks, an underground concrete waste oil vault, ENVIRONMENTAL PLANNERS · SCIENTISTS · GEOLOGISTS AND ENGINEERS Contaminated Site Assessments * Real Estate Audils * Site Remediation * Hazardous waste Management ~ ] HOLGUI Ms..Roro, Darling' ~ FAHAN KCRM'A-DEHS ~ & ~TES, INC. September 2. 1993- Page 2 ENVIRONMENTAL MANAGEMENT CONSULTANTS and a storm water drain In the southeast corner of the property (see Figure 2 - Plot Plan). The KCRM^-DEHS requested in their letter dated August 17, 1993, that a site investigation be performed to if the former operation of these features has resulted in a release of hazardous materials to the subsurface. 2. SOIL INVESTIGATION Drilling _~,~ A total of three boreholes will be drilled during this preliminary soil investigation (Figure 2). Borehole B-1 will be drilled to a depth of 30 feet BGL adjacent to the north side of the Class V o,,ow w,,, 0r,,, 0,oo t,~,,~/' ,~,..~est side of the underground waste oil vault. Borehole B-3 will be drilled to a depth ot ~-~.",,,~',0'~' 30 tee~BGL adjacent to the west side of the storm water drain Soil sampling will be i ' ~j~ performed at five-foot intervals in each of the boreholes. Laboratory analysis will be performed on two soil samples from the boreholes based upon field screening, as well as analyzing the sample from immediately beneath the bottom of the two features. Chemical Analysis of Soil Samples Soil samples will be sent to BC Laboratories, a California state-certified laboratory, for chemical analysis. Based on field observations, approximately slx soil samples will be selected for laboratory analysis. Soil samples will be analyzed for TPH, BTEX, and halogenated hydrocarbons (solvents) by EPA Method 8260. Additionally, one sample from each borehole having the highest PID reading observed during drilling will be analyzed for the California Title 22 metals. Report Preparation Upon successful completion of the drilling activities, HFA will provide a preliminary soil assessment report that details the field activities, sample collection, analytical results, data analysis, conclusions, and HFA's recommendation for further assessment or remedial activities, if required. Certified laboratory reports and chain-of-custody documents will be included. Schedule and Conditions upon approval of the work plan by KCRMA-DEHS and with the authorization of the property owner, HFA will conduct the drilling activities within tiMe working days. Laboratory turnaround wilt be ten working days, and the preliminary soil assessment report will be provided to the client within two weeks of receipt of the laboratory analysis results.

Darling ~ Kern County Resources Management Agency Department of Environmental Health Services 2700 M Street, Suite 300 Bakersfield, California 93301 SUBJECT: WORK PLAN FOR PRELIMINARY SITE ASSESSMENT INLAND KENWORTH, 3012 PIERCE ROAD, BAKERSFIELD, CALIFORNIA Dear Ms, Darling: The following work plan outlines Holguin, Fahan & Associates, Inc.'s (HFA) proposed O methodology for the preliminary assessment of possible hydrocarbon-containing soils associated with the former operation ota USEPA Class V shallow disposal well, and an underground concrete waste oil vault at the above referenced site. HFA proposes to advance two boreholes to a depth of 30 feet below ground level (BGL) and analyze 4 soil samples for the pre'sence of total petroleum hydrocarbons (TPH), the volatile aromatics benzene, toluene, ethylbenzene, and total xylenes (BTEX), and halogenated hydrocarbons (solvents), as well as one sample from each boring analyzed for the California Title 22 Metals. 1. PURPOSE AND SCOPE The purpose of this work plan is to outline the methodology to be followed for the assessment of the possible hydrocarbon-containing soils at the subject site. The proposed scope of work for this project includes the following major tasks: · develop a work plan and site specific health and safety plan for the assessment of possible hydrocarbon-containing soils associated the former operation of the Class V shallow disposal well, and underground waste oil vault at the Inland Kenworth facility; · advance two boreholes to a depth of 30 feet BGL; · analyze 4 samples for the presence of TPH, BTEX and solvents, as well as one sample from each borehole for the California Title 22 metals; and · prepare a preliminary site assessment report documenting the drilling activities, sample results data analysis, conclusions, and recommendations for any further action that may be necessary.

Site Description The site is located at 3012 Pierce Road in the unincorporated area west of the city of Bakersfield in Kern County, California (see Figure 1 - Site Location Map). The project site is bounded on the west by Pierce Road, on the south by Don Keith Trucking Company, on the east by the Office Depot store, and on the north by the Home Base store. The property is currently operating as a large truck and bus maintenance facility. The topography of the site is relatively flat, with a slight fall to the west. The owner contact is James Hubbard with Hubbard Enviromanagement, Inc., 541 Powell Terrace, Visalia, California, 93291, (209) 635-8030. The consultant contact is Mark Magargee, Holguin, Fahan & Associates, Inc., 2820 Pegasus Drive, Bakersfield, California, 93308, (805) 391-0517. Site History Central California Kenworth operates a steam wash in a service bay at the property (see Figure 2 - Plot Plan). The floor drain formerly connected to a pipeline which led to four septic tanks in series along the southern property line. On August 25, 1988, representatives of the U. S. Environmental Protection Agency (USEPA) conducted an inspection of the property to determine whether any practices at the property presented a threat ta groundwater resources. At that time they noted that the septic tank system connected to the floor drain warranted further investigation as a potential Class V shallow disposal well. Subsequently, the KCRMA-DEHS received funaing through the USEPA to conduct a pilot program for local enforcement of Class V shallow disposal wells. On January 8, 1993 a water sample was collected by KCRMA-DEHS from the septic tanks. The sample was analyzed for Total Petroleum Hydrocarbons as gasoline, diesel and oil & grease, volatile organics, and California Title 22 metals. KCRMA-DEHS reviewed the analytical data, and determined that USEPA standards had not been exceeded. Kenworth was instructed to disconnect the piping leading from the floor drain to the septic tanks, and abandon the septic tanks in- place by filling with a cement-sand slurry. Kenworth performed the first task by disconnecting the piping. HFA completed the second task of septic tank abandonment on August 11, 1993. HOLGUI Inland Kenworth ~ FAHAN Bakersfield, California August 25, 1993 - Page 3 & A SOCJATES, INC. ENVIRONMENTAL MANAGEMENT CONSULTANTS The septic tanks were abandoned by HFA on August 11, 1993 by gerforming the following tasks: 1) the surface lids of the septic tanks were exposed and removed, 2) a vacuum truck removal any remaining liquid within the septic tanks, 3) a plug was placed in the inlet piping from the floor drain to the first septic tank, 4) the septic tanks were pressure washed to remove any residual substances from the walls of the tanks, 5) the vacuum truck removed the rinsate from the septic tanks, 6) the septic tanks was filled with a five sack cement-sand slurry to within one feet of the top of the necks, 7) a neat cement grout was used to fill the' remaining one foot to the top of the tanks with the top surface domed to cause water to flow away from the tanks, and 8) the.vacuum truck transported the liquid from the inside the tanks to Gibson Oil and Refining's Bakersfield facility where the liquid will be disposed of. During the septic tank abandonment, the KCRMA-DEHS observed the presence of a · possible Class V shallow disposal well approximately 20 feet east of the septic tanks, as well as an underground concrete waste oil vault in the southeast corner of the property (see Figure 2). The KCRMA-DEHS requested in their letter dated August 17, 1993, that a site investigation be performed to if the former operation of these features has resulted in a release of hazardous materials to the subsurface. 3. GEOLOGY AND HYDROGEOLOGY The site is located in a relatively flat area at an elevation of approximately 500 feet above mean sea level. 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, the southern portion of which is known as the San Joaquin Valley. The surface of the San JoaquJn Valley is composed primarily of unconsolidated Pleistocene-age (1.6 million to 11,000 years ago) and Recent-age (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 30,000 feet. Geologic deposits in the study area include Pleistocene-age alluvial sediments of the Kern River Formation, which form a homocline dipping gently to the southwest. The deposits are alluvium consisting of poorly indurated and dissected fan deposits (California Department of Mines and Geology, 1964). ~J HOLGUI ,N~ Inland Kenworth ~ FAHAN Bakersfield, California ~ 8,. TES, INC. August 25, 1993- Page 4 ENVIRONMENTAL MAN~,GEMENT CONSULTANTS This is an area at the foot of rolling hills with a maximum elevation of 900 feet MSL, located on the eastern flank of the San Joaquin Valley and west of the southern Sierra Nevada. The Kern River drains a large area of the southern Sierra Nevada, including the highest part of the range at Mount Whitney. The modern river has cut a channel southeast of the site and provides recharge for groundwater along its course. Sedimentary geologic formations, observed at the surface and underlying the site, were sourced by the Sierra Nevada and transported via the ancestral Kern River. In the region of the site, the Tertiary sedimentary sequence, from top to bottom, is nonmarine Kern River Formation (Tkr), nonmarine Chanac Formation (Tch), marine "Santa Margarita" Formation (possibly interfingering with Chanac Formation due to tentative correlation of type Santa Margarita Formation section west of the San Andreas fault), marine Round Mountain Silt, marine Olcese Sand, marine Freeman Silt, marine Jewett Sand and Pyramid Hill member, marine Vedder Sand, nonmarine Walker Formation. Of these, only the Kern River Formation, Chanac, and "Santa Margarita" are important to the hydrogeology of the site. The Tertiary nonmarine Kern River Formation (TkO is unconformably overlain by bouldery terrace deposits of Quaternary Older Alluvium (Qoa). Two naturally occurring geologic units are present in the near surface at the site. The two natural units are the Tertiary (Miocene to Pliocene) nonmarine Kern River Formation, and Quaternary (Pleistocene) Older Alluvium (Qoa). The Qoa forms a thin terrace deposit lying unconformably on the Kern River Formation. Quaternary Older Alluvium(Qoa) is middle to lower Pleistocene age (Qoa2 of Bartow, 1984). Qoa is a flat lying terrace deposit approximately 5 feet thick which overlies the erosional surface of the Kern River Formation. Qoa is comprised of very coarse material, with boulders to 50cra in diameter. Clastic material composition includes granitic and dioritic crystalline rocks characteristic of the Sierra Nevada batholiths, quartzite characteristic of pre-batholithic rocks, and volcanic and related rocks such as andeslte and dark siliceous agate typical of Neogene deposits of the Mojave desert. In some locations caliche rims have developed between clasts, Kern River Formation (Tkr) The age of the Kern River Formation includes upper Miocene and Pliocene, and possibly Pleistocene. The Kern River Formation is comprised of interstratified fanglomeratic deposits and silty claystones. Within the fanglomerates are conglomerate beds with cobbles to 20cra in diameter, and in some areas fanglomerate ~~--~ HOLGUINe 'Inland Kenworth ~ FAHAN Bakersfield; California ~ & ASSOC T , lNG. August 25, 1993- Page 5 ENVIF::tONMENTAL MANAGEMENT CONSULTANTS beds exhibit cross bedding 2.5 to 5 meters thick. The silty claystone beds, which would serve as Iow permeability barriers to vertical migration, are laterally continuous as much as several thousand feet, but are locally truncated by sandy fanglomerate units. Another important factor in considering the potential for migration is the lack of secondary permeability within the Kern River Formation as no secondary cracks, small faults or gypsum veins are observed. Chanac Formation ~'Tch) The Chanac Formation of upper Miocene age, is not exposed on or near the site, but outcrops in the cliffs east of the site along the Kern River bluffs at Hart Park. It is a thinly bedded chalky siltstone exhibiting many secondary cracks and gypsum veins. Soil borings advanced by the consultant on an adjoining property indicate that the alluvium is characterized by unconsolidated, moderate to good permeability silty sand to a depth of approximately 7 feet below ground level (BGL), overlying unconsolidated, highly permeable, fine-grained to coarse-grained sand to a depth of approximately 23 feet BGL. Underlying this is a zone of unconsolidated, highly permeable, fine-grained to coarse- grained sand and gravel to a depth of approximately 38 feet BGL. This is underlain by unconsolidated, highly permeable, fine-grained to coarse-grained silty sand to a depth of 46 feet BGL. Underlying this is a zone of consolidated, Iow permeability, clayey silt to a depth of 48.5 feet BGL, which was the greatest depth drilling during that investigation. 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 southernmost being the Kern River. The subject site Is located approximately one half mile north of the Kern River. The depth to the regional unconfined aquifer is approximately .50 feet BGL beneath the site with the direction of groundwater flow to the west-northwest (Kern County Water Agency, 1991 Report on Water Conditions, Improvement District No. 4, February 1992). 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 Ker'n Lake bed (Kern County Water Agency, 1991 Water Supply Report, May 1992). No perched groundwater is known to exist beneath the subject site. 4.

One borehole (B-l) will be drilled to a depth of 30 feet BGL adjacent to the north side of the Class V shallow disposal well. The other boreholes (B-2) will be drilled to a depth of 30 feet BGL adjacent to the west side of the underground waste oil Vault. Soil sampling will be performed at five-foot intervals in each of the boreholes. See Attachment 2 for HFA's soil sampling protocols. Laboratory analysis will be performed on two soil samples from the boreholes based upon field screening, as welt as analyzing the sample from immediately beneath the bottom of the two features. Chemical Analysis of Soil Samples Soil samples will be sent to BC Laboratories, a California state-certified laboratory, 'for chemical analysis. Based on field observations, approximately 4 soil samples will be selected for laboratory analysis. Soil samples will be analyzed for TPH, BTEX, and halogenated hydrocarbons (solvents) by EPA Method 8260. Additionally, one sample from each borehole having the highest PID reading observed during drilling will be analyzed for the California Title 22 metals. Report Preparation Upon successful completion of the drilling activities, HFA will provide a preliminary soil assessment report that details the field activities, sample collection, analytical results, data analysis, conclusions, and HFA's recommendation for 'further assessment or remedial activities, if required. Certified laboratory reports and chain-of-custody documents will be included. schedule and Conditions Upon approval of the work plan by KCRMA-DEHS and with the authorization of the property owner, HFA will conduct the drilling activities within rive working days. Laboratory turnaround will be ten working aays, and the preliminary soil assessment report will be provided to the client within two weeks at receipt of the laboratory analysis results. All work will be accomplished in accordance with the regulatory requirements defined by the State Water Resources Control Board Leaking Underground Fuel Tank manual, SDW-100 "Closure of Shallow Disposal Wells", and the KCRMA-DEHS guidance documents for report preparation. .~~~~ HOLGUIN, - · Inland Kenworth FAHAN Bakersfield, California & ~_'~OCI~T~, INC.

ENVIRONMENTAL MANAGEMENT CONSULTANTS HEALTH AND SAFETY PLAN FOR UNDERGROUND STORAGE TANK SITE RENIEDIATIONS This document outlines Holguin, Fahan & Associates, Inc.'s (HFA) health and safety plan for Kern County site assessments. Site-specific information is provided on the cover page to this document. This health' and safety plan was developed by HFA's industrial hygienist through consultation of the following documents: · OSHA29CFR 1910 - "Hazardous Waste Operations and Emergency Response, Final Ruling," March 1989; · NIOSH/OSHA/USCG/EPA "Occupational Safety and Health Guidance Manual for Hazardous Waste Site Activities," October 1985; and · HFA's Corporate Standard Safety Program. This health and safety plan is divided into the following categories: 1. Job Hazard Assessment 2. Exposure Monitoring Plan 3. Personal Protective Equipment 4. Work Zones and Security Measures 5. Decontamination and Disposal 6. Worker Training 7. Emergency Procedures 1. JOB HAZARD ASSESSMENT Immediate tasks at any site assessment include an evaluation of any present or potential threat to public safety. Questions need to be answered regarding the dangers of significant vapor exposures and potential explosion hazards. POTENTIAL CHEMICAL HAZARDS The chemical components of petroleum hydrocarbons that are the most dangerous to site workers are the volatile aromatics benzene, toluene, ethylbenzene, xylene, and potentially, organic lead. Additionally, solvents such as 1,2-dichlorobenzene and 1,2-dichloroethane may also be used as cleaning solutions at service stations. The primary health risks associated with each of these chemicals are described below. Benzene - Suspected human carcinogen, A TLV of 10 ppm or 30 mg/m3 has been assigned to benzene, Benzene has a Iow odor threshold limit of 1,4 ppm. Low level inhalation exposure to benzene can cause irritation to the eyes, nose and respiratory system, headache, and nausea. Ne Health and Safety Plan HOLGUIFAHAN Page2 & ASSOCIATES, INC. ENVIRONMENTAL MANAGEMENT CONSULTANTS Toluene - A TLV OF 100 ppm or 375 mg/m3 has been assigned to toluene. Toluene has a Iow odor threshold limit of 2.1 ppm. Low level inhalation exposure to toluene can cause fatigue, weakness, confusion, and euphoria. Ethylbenzene - A TLV of 100 ppm or 435 mg/m3 has been assigned to ethylbenzene. Ethylbenzene has a Iow odor threshold limit of 2 ppm, Low level inhalation exposure to ethylbenzene can cause irritation to the eyes and mucous membranes. Xylene - A TLV of 100 ppm or 435 mg/m3 has been assigned to xylene. No Iow odor threshold limit has been established for xylene. Low level inhalation exposure to xylene can cause dizziness, excitement, and drowsiness. 1,2-Dichlorobenzene A TLV of 50 ppm or 306 mg/m3 has been assigned to 1,2-dichlorobenzene. 1,2-dichlorobenzene has a Iow odor threshold limit of 4,0 ppm. Acute vapor exposure can cause coughing, dizziness, and drowsiness. It may cause skin irritation. 1,2-Dichloroethane - A TLV of 200 ppm has been assigned to 1,2:dichloroethane, No data is available concerning odor threshold. Acute vapor exposure can cause coughing, dizziness, and drowsiness. It may cause skin irritation. Tetraethyl Lead - A TLV of 0.1 mg/m3 has been assigned to tetraethyl lead. Tetraethyl lead is a colorless or red-dyed liquid at atmospheric conditions. No data is available concerning odor threshold. Acute vapor exposure can cause insomnia, delirium, coma, and skin irritation. POTENTIAL PHYSICAL HAZARDS Trenchin.q - Dangerously high fuel vapor levels will be monitored using a lower explosive limit (LEL) meter. The presence of underground utilities also are of concern and the Underground Service Alert will be notified in advance of any drilling work for identification of all underground utilities in the immediate area. Drilling - Dangerously high fuel vapor levels will be monitored using an LEL meter. The presence of underground utilities also are of concern and Underground Service Alert will be notified in advance of any drilling work for identification of all underground utilities in the immediate area. Samplin.g Use of personal protective equipment will minimize the exPosure of site investigations. Heat stress will be monitored by each individual and controlled through regular work breaks as outlined in the American Conference of Governmental Industrial Hygienists' TLV's for heat stress conditions.

ATI'ACHMENT 2. SOIL SAMPLING PROTOCOLS BOREHOLE DRILLING AND SOIL SAMPLING PROCEDURES SITING Soil borings will be positioned as noted in th'e work plan. TRUCK-MOUNTED DRILLING AND SOIL SAMPLING PROCEDURES Each borehole will be manually drilled for the first four feet in order to establish that the area was clear of subsurface structures. The borings will be drilled with 8-inch outside diameter, hollow-stem, flight augers to the depths noted in the work plan. During the drilling process, soil cuttings will be continuously monitored in conformance with the monitoring procedures, and data will be recorded'on soil boring logs by an experienced environmental geologist under the direct supervision of a State of California registered geologist. Soil samples will be collected with a California split-spoon sampler at intervals consistent with the work plan, unless a change in lithology was noted, in which case an additional sample will be collected. The sampler will be outfitted with 2.5-inch by 6-inch stainless steel or brass sleeves. When the sample is withdrawn, the ends of the sleeve are covered with aluminum foil or TeflonTM tape followed by plastic caps. Sample preservation, handling, and transportation procedures will be consistent with HFA's QA/QC procedures. BOREHOLE MONITORING PROCEDURES Cuttings from soil borings will be continuously classified according to the Unified Soil Classification System (USCS) and logged by an experienced environmental geologist under the direct supervision of a State of California registered geologist. Specific geologic and hydrologic information that will be collected include stratigraphy ri.e,, layer thickness, unit correlation, aquifer thickness, depth to groundwater, and confining units, if any), relative permeability, observed porosity, plasticity, moisture content, soil type, structure, size, and other features that could affect contaminant transport. Specific geologic and hydrologic information that will be obtained during borehole construction includes the following: · stratigraphic characteristics: thickness, correlation of units, extent (horizontal and vertical) of aquifers and confining units, if any; · observed porosity; · volatile organic content; · particle-size distribution; · moisture content; · plasticity; · strength; Soil' BOri~~ ~ .e~_~lres~ ' ~ F~N .... =?'~r:'?"

ENVIRONMENTAL MANAGEMENT CONSULTANTS All field logs will be typed and presented verbatim in an appendix of the preliminary soil assessment report. The typed soil boring logs will be on a form identical to that used in the field log book. Each soil boring log includes a graphic log in which a symbol for each USCS soil group is included for each soil interval. DATA REDUCTION The data compiled from the soil borings will be summarized and analyzed. A narrative summary of the soil characteristics will also presented. The soil boring logs are checked for the following information: · correlation of stratigraphic units among boreholes; · identification of zones of potentially high hydraulic conductivity; · identification of the confining formation/layer; · indication of unusual/unpredicted geologic features (fault zones, fracture traces, facies changes, solution channels, buried stream deposits, cross-cutting structures, pinchout zones, etc.); and · continuity of petrographic features such as sorting, grain-size distribution, cementation, etc. Borehole locations will be plotted on a properly scaled map. The purpose of each borehole/piezometer/monitoring well/pit/soil sample is indicated on the map. Depending on the results of this analysis, the soil stratigraphy of the site is presented in a scaled stratigraphic column (if soil stratigraphy is laterally homogeneous) or, more likely, in a scaled cross section or a fence diagram (if soil is laterally heterogeneous). Specific features that may impact contaminant migration, e.g., fault zones or impermeable layers, will be discussed in narrative form and supplemented with graphical presentations as deemed appropriate. DECONTAMINATION PROCEDURES Prior to each sampling episode, the sampling equipment will be decontaminated using a non-phosphate soap wash, a tap water rinse, and two deionized water rinses. The drill string will be decontaminated with a steam cleaner between each well/boring. & INC. ENVIRONMENTAL MANAGEMENT CONSULTANTS BOREHOLE ABANDONMENT The boreholes will be abandoned with a 5% bentonite neat cement grout delivered by a grout pump through a tremmie pipe. WASTE MANAGEMENT AND DISPOSAL The cuttings trom the boreholes will be stored in 55-gallon, Department of Transportation drums. Each drum will be labeled with the date that the waste was generated and the numbers of the soil borings from which the waste was withdrawn. The drums will be stored at the site of generation until sample analyses were obtained. Sample analyses and an inventory of drums wilt be then given to Mr Jim Hubbard, who will coordinate on-site treatment or proper disposal of the soil, according to Regional Water Quality Control Board requirements.

The areas include the concrete vault located southeast of the septic tanks. The steel cover was removed, and a visual inspection was performed. The vault contains oily sludge. Sampling of the contents must be performed. Between the vault and the abandor3ed septic tanks there is a steel pipe extending to subsurface, which appears to be an injection well. Also noted is a grated drain, positioned to the north of the concrete vault. It is not clear at this time if the former septic tanks were connected to the injection well, or if there is a connection extending from the concrete vault to the injection well. All of these areas must be investigated by the methods described in guidance document SDW-100, "Closure of Shallow Disposal Wells." Please contact your environmental contractor with instructions to provide this office with an addendum workplan addressing the above items. The workplan must reach this office within fourteen (14) days of receipt of this letter. Any questions you may have regarding this notice should be directed to me at (805) 861-3636, Extension 549.

S, INC. Bakersfield, California ENVIRONMENTAL MANAGEMENT CONSULTANTS August 16, 1993 - Page 2 TOPOGRAPHY, GEOLOGY, AND HYDROGEOLOGY The site is located in a relatively flat area at an elevation of approximately 500 feet above mean sea level. 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, the southern portion of which is known as the San Joaquin Valley. The surface of the San Joaquin Valley is composed primarily of unconsolidated Pleistocene- age (1.6 million to 11,000 years ago) and Recent-age (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 30;000 feet. Geologic deposits in the study area include Pleistocene-age alluvial sediments of the Kern River Formation, which form a homocline dipping gently to the southwest. The deposits are alluvium consisting of poorly indurated and dissected fan deposits (California Depaffrment of Mines and Geology, 1964). This is an area at the foot of rolling hills with a maximum elevation of 900 feet MSL, located on the eastern flank of the SanJoaquin Valleyand west of the southern Sierra Nevada. The Kern River drains a large area of the southern Sierra Nevada, including the highest part of the range at Mount Whitney. The modern river has cut a channel southeast of the site and provides recharge for groundwater along its course. Sedimentary geologic formations, observed at the surface and underlying the site, were sourced by the Sierra Nevada and transported via the ancestral Kern River. In the region of the site, the Tertiary sedimentary sequence, from top to bottom, is nonmarine Kern River Formation (Tkr), nonmarine Chanac Formation (Tch), marine "Santa Margarita" Formation (possibly interfingering with Chanac Formation due to tentative correlation of type Santa Margarita Formation section west of the San Andreas fault), marine Round Mountain Silt, marine Olcese Sand, marine Freeman Silt. marine Jewett Sand and Pyramid Hill member, marine Vedder Sand, nonmarine Walker Formation. Of these, only the Kern River Formation, Chanac, and "Santa Margarita" are important to the hydrogeology of the site. The Tertiary nonmarine Kern River Formation (Tkr) is unconformably overlain by boulderyterrace deposits of Quaternary Older Alluvium (Qoa). Two naturally occurring geologic units are present in the near surface at the site. The two natural units are the Tertiary (.Miocene to Ptiocene) nonmarine Kern River Formation, and Quaternary (Pleistocene) Older Alluvium (Qoa). The Qoa forms a thin terrace deposit lying unconformably on the Kern River Formation. FAHAN Central California K~nWorth "'~ & h~I~'~T~, lNG. Bakersfield. California ENVIF::IONMENTAL MANAGEMENT CONSULTANTS * --/~UgUST 16, 1993 - Hage.3 Quaternary Older AlluvJum(Qoa) is middle to lower Pleistocene age (Qoa2 of Bartow, 1984). Qoa is a flat lying terrace deposit approximately 5 feet thick which overlies the erosional surface of the Kern River Formation. Qoa is comprised of very coarse material, with boulders to 50cm in diameter. Clastic material composition includes granitic and dioritic crystalline rocks characteristic of the Sierra Nevada batholiths, quartzite characteristic of pre-batholithic rocks, and volcanic and related rocks such as andesite and dark siliceous agate typical of Neogene deposits of the Mojave desert. In some locations caliche rims have developed between clasts. Kern River Formation (TkO The age of the Kern River Formation includes upper Miocene and Pliocene, and possibly Pleistocene. The Kern River Formation is comprised of interstratified fanglomeratic deposits and silty claystones. Within the fanglomerates are conglomerate beds with cobbles to 20cm in diameter, and in some areas fanglomerate beds exhibit cross bedding 2.5 to 5 meters thick. The silty claystone beds, which would serve as Iow permeability barriers to vertical migration, are laterally continuous as much as several thousand feet, but are Iocalty truncated by sandy fanglomerate unh's. Another important factor in considering the potential for migration is the lack of secondary permeability within the Kern River Formation as no secondary cracks, small faults oi gypsum veins are observed. Chanac Formation (1'ch) The Chanac Formation of upper Miocene age, is not exposed on or near the site, but outcrops in the cliffs east of the site along the Kern River bluffs at Hart Park. It is a thinly bedded chalky siffstone exhibiting many secondary cracks and gypsum veins. Soil borings advanced by the consultant on an adjoining property indicate that the alluvium is characterized by unconsolidated, moderate to good permeability silty sand to a depth of approximately 7 feet below ground level (BGL), overlying unconsolidated, highly permeable, fine-grained to coarse-grained sand to a depth of approximately 23 feet BGL. Underlying this is a zone of unconsolidated, highly permeable, fine-grained to coarse-grained sand and gravel to a depth of approximately 38 feet BGL. This is underlain by unconsolidated, highly permeable, fine-grained to coarse-grained silty sand to a depth of 46 feet BGL. Underlying this is a zone of consolidated, Iow permeability, clayey silt to a depth of 48.5 feet BGL, which was the greatest depth drilling during that investigation. 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 southernmost being the Kern River. The subject site is located approximately one halt mile northofthe Kern River. The depth to the ~egional unconfined aquifer is approximately 50 feet ~ FAHAN CentraICalifornia Kenworth & ASSOCIATe, INC. Bakersfield, California ENVII=tONMENT~,I- IVL~N~.I~EMENT CONSULT.,~NTS Au(~Just 16, 1993 - Page 4 below ground level (BGL) beneath the site with the direction of groundwater flow to the west- northwest (Kern County Water Agency, 1991 Report on Water Conditions, Improvement District No. 4, February 1992). 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. SEPTIC TANK HISTORY Central California Kenworth operates a steam wash in a service bay at the property (see Figure 2 - Pict Plan). The floor drain formerly connected to a pipeline which led to four septic tanks in series along the southern property line. PREVIOUS WORK On August 25, 1988, representatives of the U. S. Environmental Protection Agency (USEPA) conducted an inspection of the property to determine whether any practices at the property presented a threat to groundwater resources. At that time they noted that the septic tank system connected to the floor drain warranted further investigation as a potential Class V shallow disposal well. Subsequently, the KCRMA-DEHS received funding through the USEPA to conduct a pilot program for local enforcement of Class V shallow disposal wells. On January 8, 1993 a water sample was collected by KCRMA-DEHS from the septic tanks. The sample was analyzed for Total Petroleum Hydrocarbons as gasoline, diesel and oil & grease, volatile organics, and California'Title 22 metals. KCRMA-DEHS reviewed the analytical data, and determined that USEPA standards had not been exceeded. Kenworth was instructed to disconnect the piping leading from the floor drain to the septic tanks, and abandon the septic tanks in-place by filling with a cement-sand slurry, Kenworth performed the first task by disconnecting the piping. HFA completed the second task of septic tank abandonment on August 1 t, 1993. FAHAN Central California.KenwOrth & INC. Bakersfield; California ENVii=iONMENT~,L MANAGEMENT CON~;ULT,~,NTS August ]6, 1,993- Pages PROCEDURES FOR SEPTIC TANK ABANDONMENT The septic tanks were abandoned by HFA on August 11, 1993 by performing the following tasks: 1) the surface lids of the septic tanks were exposed and removed, 2) a vacuum truck removal any remaining liquid within the septic tanks, 3) a plug was placed in the inlet piping from the floor drain to the first septic tank, 4) the septic tanks were pressure washed to remove any residual substances from the walls of the tanks, 5) the ~acuum truck removed the rinsate from the septic tanks, 6) the septic tanks was filled with a five sack cement-sand slurry to within one feet of the top of the necks, 7) a neat cement grout was used to fill the remaining one foot to the top of the tanks with the top surface domed to cause water to flow away from the tanks, and 8) the vacuum truck transported the liquid from the inside the tanks to Gibson Oil and Refining's Bakersfield facility where the liquid will be disposed off as a California Waste Code 223 - miscellaneous petroleum liquid waste (See Attachment 1. for a copy of the Non-RCRA Hazardous Waste Liquid Manifest).

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. 4. SEPTIC TANK HISTORY: Central California Kenworth operates a steam wash in a service bay at the property (see Figure 2 - Plot Plan). The floor drain connected to a pipeline which led to four septic tanks in series along the southern property line. 5. IDENTIFICATION AND ESTIMATED QUANTITY OF MATERIAL RELEASED: Oily wash water: the quantity released is unknown. 6. PREVIOUS WORK: On August 25, 1988, representatives of the U. S. Environmental Protection Agency (USEPA) conducted an inspection of the property to determine whether any practices at the property presented a threat to groundwater resources. At that time they noted .that the septic tank system connected to the floor drain warranted further investigation as a potential Class V shallow disposal well. Subsequently, the KCRMA-DEHS received funding through the USEPA to conduct a pilot program for local enforcement of Class V shallow disposal wells. On January 8, 1993 a water sample was collected by KCRMA-DEHS from the septic tanks. The sample was analyzed for Total Petroleum Hydrocarbons as gasoline, diesel and oil & grease, volatile organics, and California Title 22 metals. KCRMA-DEHS reviewed the analytical data, and determined that USEPA standards had not been exceeded. Kenworth was instructed to disconnect the piping leading from the floor drain to the septic tanks, and abandon the septic tanks in- place by filling with a cement-sand slurry. Kenworth has performed the first task by disconnecting the piping. HFA proposes, to complete the second task of septic tank abandonment. 1~1-0~-~ .. :~:'~:?~-~;~-:." .- FA N Central Cal~ornla~Kenworth ~ ~ ~T~, I~.

PROCEDURES FOR SEPTIC TANK ABANDONMENT: The septic tanks will be abandoned by performing the following tasks: 1) the surface lids of the septic tanks wilt be exposed and removed, 2) a vacuum truck will removal any remaining liquid within the septic tanks, 3) a plug will be placed in the inlet piping from the floor drain to the first septic tank, 4) the septic tanks will be pressure washed to remove any residual substances from the walls of the tanks, 5) the vacuum truck will .remove the rinsate from the septic tanks, 6) the septic tanks will be filled with a 3 sack cement-sand slurry to within one feet of the top of the necks, 7) a neat cement grout will be used to fill the remaining one foot to the top of the tanks with the top surface domed to cause water to flow away from the tanks, and 8) the vacuum truCk will transport the liquid from the inside the tanks to Gibson Oil and Refining's Bakersfield facility where the liquid will be disposed off as a California Waste Code 223 - miscellaneous petroleum liquid waste. 8. WORK SCHEDULE: Work will begin within two days subsequent to acceptance of this work plan by the KCRMA-DEHS. The KCRMA-DEHS will be notified at least 48 hours before any on- site work commences. A report documenting the septic system abandonment will be submitted to the KCRMA-DEHS approximately two weeks after commencement of the work. All work will be accomplished in accordance with all regulatory requirements as defined by KCRMA-DEHS guidance documents. Holguin, Fahan & Associates, Inc., trusts that this work plan provides you with the information you require.

Dear Mr. Parker: This office has reviewed the laboratory reports of analyses performed on samples retrieved January 8, 1993, .by B.C. Laboratories at the address noted above. Our review has determined that hazardous waste toxicity criteria and the E.P.A. drinking water regulations/health advisories have not been exceeded in the liquid sampled in the septic tank. A telephone conference with Gary M. inner of the Bakersfield Kenworth office has confirmed that discharge lines from the building to the tanks have been sealed; however, the septic tanks formerly receiving fluids generated by steam cleaning activities are still in place. It is the opinion of this office that complete abandonment of the septic tanks by filling with a cement sand slurry would be prudent and would prevent future questions regarding the former steam cleaning discharges t° the system. A licensed contractor may provide the above service for you. Please notify this office 48 hours prior to initiating the abandonment activities in order that a hazardous materials specialist may be present. Upon proper abandonment of the tanks, a closure letter will be issued by this Department. Work should begin within 30 days of receipt of this letter. Any questions you may have should be directed to me at (805) 861-3636, Extension 549. Sincerely, ~--By~.'
