The property was recently vacated by its former tenant, Central California Kenworth (Kenworth). SITE DESCRIPTION The subject site is located at 30t2 Pierce Road in the city of Bakersfield in Kern County, California (see Figure 1). The project site is bound on the west by Pierce Road, on the south by Don Keith Trucking Company, on the east by an Office Depot retail store, and on the north by a Home Base retail store (see Figure 2 - Plot Plan). The topography of the site is relatively flat, with a slight fall to the west. The property was recently a large truck and bus maintenance facility. Kenworth ceased operations at the site during the first quarter of 1994, and has since vacated the facility. BACKGROUND PREVIOUS WORK Kenworth operated a steam wash in a service bay at the property. The floor drain was previously connected to a pipeline that led to a four-chambered septic tank along the southern property line (see Figu'~e 2). On August 25, 1988, representatives of the EPA conducted an inspection of the property to determine whether any practices at the property presented a ENVIRONMENTAL PLANNERS · SCIENTISTS · GEOLOGISTS AND ENGINEERS Contaminated Site Assessments * Real Estate Audits * Site Remediation * Hazardous Waste Management HOLGUI Mr. Dan Starkey FAHAN KCDEHS &ASSOCIATES, INC. January 25,.1995 - Page 2 ENViRONMENtAL MANAGEMENT CONSULTANTS threat to groundwater resources. At that time, it was noted that the septic tank system cbnnected to the floor drain warranted further investigation as a potential Class V shallow disposal well. The Kern County Department of Environmental Health Services (KCDEHS) subsequently received funding through the EPA to conduct a pilot program for local enforcement of Class V shallow disposal wells. On January 8, 1993, a water sample was collected by the KCDEHS from the four-chambered septic tank. Kenworth was instructed to disconnect the piping leading from the floor drain to the septic tank and abandon the septic tank in place by filling it with a cement-sand slurry. Kenworth performed the first task by disconnecting the piping and installing a self-contained, aboveground, washwater recycling system. HFA completed the second task by abandoning the septic tank on August 11, 1993. During the septic tank abandonment, the KCDEHS representative observed the presence of a possible Class V shallow disposal well approximately 25 feet east of the septic tank; an underground, concrete, waste oil vault in the southeastern corner of the property; and a storm water drain approximately 25 feet north of the waste oil vault (see Figure 2). In a letter dated August 17, 1993, the KCDEHS requested that a site investigation be performed to assess the potential for hydrocarbon=containing soils associated with the dry well, waste oil vault, and storm drain. HFA performed the drilling and sampling on September 14, 1993. Soil boring B-1 was drilled adjacent to the western side of the dry well to a total depth of 30 feet below grade (fbg). Soil boring B-2 was drilled adjacent to the northwestern corner of the waste oil vault to a total depth of 25 fbg. Soil boring B-3 was drilled through the storm water drain to a total depth of · 22.5 fbg (see Figure 2 for soil boring locations). Since groundwater was encountered in soil boring B- 1 at a depth of 28 fbg, the other two soil borings were terminated above this depth. Soil samples collected from the soil borings were tested for a petroleum fingerprint consisting Of total petroleum hydrocarbons (TPH) as gasoline; TPH as diesel; TPH as motor oil; TPH as crude oil; benzene, toluene, ethylbenzene, and total xylenes (BTEX); and common solvents using EPA Method 8260. In addition, one sample from each soil boring was tested for the California Title 22 metals. Subsequently, samples of the liquids and sludge within the waste oil vault were collected on Se~otember 17, 1993, and analyzed for TPH as'gasoline, TPH as diesel, TPH as motor oil, and TPH as crude oil, BTEX, and common solvents using EPA Method 8260. These liquid and sludge samples were also tested for TPH as oil and grease using EPA Method 418.1 as well as the California Title 22 metals. Analysis of the soil samples collected from soil boring B-2 (advanced adjacent to the northwestern corner of the waste oil vault) indicated hydrocarbon-containing soils at a depth of 10 l:bg as indicated by the presence of TPH as motor oil at a concentration of 410 rog/kg. HOLGUINe Mr. Dan Starkey FAHAN KCDEHS & ~TES, INC. January 25, 1995 - Page 3 ENVIRONMENTAL MANAGEMENT CONSULTANTS Concentrations of TPH, BTEX, and common solvents were not detected in soil borings B-1 and B-3. The California Title 22 metals were detected at concentrations consistent with native concentrations in the area (see Table 1 - Summary of Soil Sample Analytical Results for Drilling). Analysis of liquid and sludge samples collected from the waste oil vault indicated the presence of hydrocarbon-containing liquids in the form of TPH as oil and grease at a concentration of 7,400 mg/I. Concentrations of TPH as gasoline, TPH as diesel, BTEX, and common solvents were not detected, with the exception of toluene at a concentration of 0.008 mg/I, 1,2,4-tdmethylbenzene at a concentration of 0.0016 rog/I, and naphthalene at a concentration of 0.001 mg/I. Lead was detected at concentrations of 189 rog/kg for total iead in the sludge and 2.2 mg/I for soluble lead (see Table 2 - Summary of Sludge Sample Analytical Results). Therefore, the liquid contents of the waste oil vault required disposal at one of several approved recycling facilities. After the KCDEHS reviewed HFA's October 11, 1993, site assessment report, it requested in a letter dated October 26, 1993, that the waste oil vault and dry well be abandoned,.and the associated hydrocarbon-containing soils be excavated. HFA subsequently excavated the soils between February 16, 1994, and March 23, 1994. Approximately 1,300 cubic yards of hydrocarbon-containing soils were excavated from beneath the location of the two waste oil vaults to a depth of 19 fbg, beneath the dry well to a depth of 27 fbg, and beneath the oil/water separator to a depth of 15 fbg (see Table 3 - Summary of Soil Sample Analytical Results for Excavation). The excavated hydrocarbon-containing soils were then transported to a road materials recycling facility for disposal. Groundwater was observed in the base of the dry well excavation at a depth of 27 fbg. The excavation pits were subsequently backfilled with import material to surface grade. During the course of the cleaning of the underground concrete waste oil vault, a second vault, which was entirely buried, was discovered to the east of the first vault. The two vaults were connected by an adjoining pipe and contained a significant amount of used oil filters and rags. These were segregated, containerized, anO disposed of at an appropriate recycling facility. Both vaults were cleaned, removed, and properly disposed. During the removal of the dry well, no piping was discovered connecting the dry well to the previously abandoned four-chambered septic tank. Instead, a pipe was discovered leading to the east, away from the septic tank. The KCDEHS requested that the pipe be exposed and removed. The course of the pipe was discovered to proceed east to the property line, north behind the two waste oil vaults, then northwest to the eastern end of the service bay building. The piping leading to the service bay building was discovered to be the effluent from a previously in-place abandoned two-chamber, wooden oil/water separator (see Figure 2). & I TES, INC. January 25.1~;x;~5- Page 4 ENVIRONMENTAL MANAGEMENT CONSULTANTS An inlet pipe was observed exiting from the western side of the wooden oil/water separator leading toward the floor drain of the steam wash. This newly identified system appears to have been a predecessor of the four-chambered septic tank system. Abandonment of the system was completed by removing the wooden oil/water separator and backfilling the steam wash floor drain with a cement grout. The KCDEHS representative aJso observed a metal plate, flush with the concrete floor, welded to the top of an 8-inch-diame.~er pipe within the westernmost service bay. HFA removed the plate and discovered a 100-foot-deep water well under the concrete foundation of the service bay. The well was sampled to determine that no hazardous materials were present in the groundwater and subsequently abandoned under permit with the KCDEHS by backfilling with a cement grout. A single soil boring was drilled on September 20, 1994, to a depth of 50 fbg, and was subsequently completed as a groundwater monitoring well in the location of the former dry well. The well was constructed with 20 feet of blank schedule 40 PVC well casing from the surface to a depth of 20 fbg and 30 feet of 0.02-inch perforated schedule 40 PVC well casing from a depth of 20 to 50 fbg On September 27, 1994, a representative groundwater sample was collected from on-site monitoring well MW-1 (see Figure 2 for monitoring well location). Before sampling, the monitoring well was checked for an immiscible layer, and none was found. Concentrations of TPH as gasoline, TPH as diesel,.TPH as oil and grease, and BTEX were not detected in the groundwater sample collected during the initial sampling event (see Table 4 - Summary of Groundwater Sample Analytical Results) SITE GEOLOGY The site is located in a relatively flat area at an elevation of approximately 500 feet above mean sea level (MSL). 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 Valle9 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 aIluvial sediments are older, predominantly lake bed deposits. These lie unconfa~'mably on Mio~Pliocene marine sediments, which extend to crystalline basement at a depth of approximately 30,000 fbg. Geologic deposits in the study FAHAN KCDEHS & ASSOCIATES, ING. January 25, 1995- Page 5 ENVIRONMENTAL MANAGEMENT CONSULTANTS 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 Division of Mines and Geology, 1964). This is an area at the foot of rolling hills with a maximum elevation of 900 feet above 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 non-marine Kern River Formation, non-marine Chanoc Formation, marine Santa Margarita Formation (possibly interfingering with Chanac Formation due to, the tentative correlation of a 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, and non-marine Walker Formation. Of these, only the Kern River, Chanac, and Santa Margarita formations are important to the hydrogeology of the site. The Tertiary, non-marine Kern River Formation is unconformably overlain by bouldery terrace deposits of Quaternary Older Alluvium. Two naturally occurring geologic units are present in the near surface at the site. The two natural units are the ~-e'rtiary (Miocene to Pliocene), non-marine Kern River Formation, and the Quaternary (Pleistocene), Older Alluvium. The Older Alluvium forms a thin terrace deposit lying unconformably on the Kern River Formation. 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 0.5 mile north of the Kern River. The depth to the regional unconfined aquifer has been measured at approximately 50 fbg beneath the site with the direction of groundwater flow to the west-northwest (Kern County Water Agency (KCWA), 1992 Report on Water Conditions, Improvement District #4, February 1993), However, due to the significant amount of precipitation during the winter of 1993, and the ongoing use of excess surface waters by the KCWA in nearby, groundwater recharge basins, groundwater was observed by HFA at a depth of 28 fbg during the September 1993, soils investigation; at a depth of 27 fbg during the OLGUI Mr. Dan Starkey IAHAN KCDEHS & A.SE,qOC_.IAT , ING. January 25, 1995- Page 6 ENVIRONMENTAL MANAGEMENT CONSULTANTS March 1994, soils excavation; and at a depth of 29 fbg during the current groundwater assessment activities. MONITORING METHODS On December 5, 1994, a representative groundwater sample was collected from on-site monitoring well MW-1 (see Figure 2 for monitoring well location). Prior to sampling, the monitoring well was checked for an immiscible layer, and none was found. The well was then purged prior to extracting a sample representative of the in-situ groundwater. During the purging process, the conductivity, temDerature, and pH of the groundwater was monitored and recorded on a water sample Iog. Purging continued until 5 casing volumes were produced and the measured parameters were at a relatively stable state. The groundwater sample was collected after the wet! had recharged to greater than 80 percent of its initial static water level (see Attachment 1 for groundwater well installation and monitoring procedures and Attachment 2 for the water sample log). A cfisposable TeflonTM bailer was used to sample monitoring well MW-1. The sample collected for analyses of TPH as gasoline, TPH as diesel, TPH as oil and grease, and BTEX was placed in a chilled, volatile organic analysis vial containing hydrochloric acid as a preservative. The sampl'e was labeled, sealed, and recordecJ on a chain-of-custody record in accordance with the procedures outlined in the KCDEHS guidance document. The groundwater sample contained no visible suspended matter, and no headspace was observed in the container. The sample was placed in a container filled with Blue-IceTM for cooling purposes and was transported to HFA Environmental Laboratories, a California state-certified laboratory, for analysis (see Attachment I for procedures). ANALYTICAL RESULTS OF GROUNDWATER SAMPLES The groundwater sample collected from monitoring well MW-1 was analyzed for concentrations of TPH os gasoline and TPH as diesel using DHS-TPH Method, TPH as oil and grease usin~ EPA Method 418.1, and BTEX using EPA Method 602. Concentrations of TPH as gas'aline, TPH as diesel, and BTEX were not detected in the groundwater sample. However, TPH as oil and grease was detected at a concentration of 3mg/I (see Table 4 and Attachment 3 for the laboratory report). HOLGUINe Mr. Dan.Starkey. FAHAN KCDEHS ~ &ASSOCIATES, INC. January 25, 1995- Page 7 ENVIRONMENTAL MANAGEMENT CONSULTANTS After two consecutive quarters of groundwater sampling wherein TPH as gasoline, TPH as diesel, and BTEX were not detected and a minor concentration of TPH as oil and grease was detected during the fourth quarter 1994, inland Industries, Inc., requests that the KCDEHS consider the site for a No Further Action (NFA) determination and permit the abandonment of the monitoring well. ACTIVITIES PLANNED FOR THE FIRST QUARTER OF 1995 If the KCDEHS concurs with a NFA determination for the Inland Industries, Ltd., property, the following activity will be completed during the first quarter of 1995: · abandonment of the groundwater monitoring well under permit with the KCDEHS. Holgu'in, Fahan & Associates, Inc., trusts that you will find, this fourth quarter 1994 groundwater assessment report to your satisfaction.

GROUNDWATER WELL INSTALLATION AND MONITORING PROCEDURES GROUNDWATER WELL INSTALLATION AND MONITORING PROCEDURES SITING The monitoring well was positioned as noted in the report. DRILLING PROCEDURES The soil boring for installation of the monitoring well was drilled with an 8-inch outside diameter, hollow-stem, flight auger to a depth of 20 feet below the top of the water table. Cuttings from the soil boring were logged by an experienced environmental geologist under the supervision of a state of California registered geologist. The soil was classified according to the standard Unified Soil Classification System. Observations regarding the types and quantities of waste materials encountered and any photoionization detector readings were logged. All data collected during the drilling of the soil boring was recorded on a soil boring log. CONSTRUCTION MATERIALS The monitoring well was constructed of 2-inch PVC casing with the blank casing extending from surface grade to 10 feet above the top of the groundwater. Slotted casing extends from 10 feet above to 20 feet below the top of the groundwater. The well was designed in accordance with Department of Health Services and State Water Resources Control Board guidance manuals. The specifications are listed in the table on the following page. :lwater Well Installation and Monitoring Procedures Page 2 MONITORING WELL SPECIFICATIONS Casing Size: Two-inch inside diameter. Casing Materials: Schedule 4[:] PVC. Filter Pack: Washed Monterey sand extending no more than 3 feet above the well screen. Sealant: Three feet of sodium bentonite immediately over the filter pack. Cement and bentonite mixture used as annular sealant from the top of the bentonite seal to the ground surface (2 to 5 percent bentonite by weight). Well Covers: Twelve-inch diameter locking aluminum access covers. Well Intake: Twenty feet of 0.02-inch slotted casing below the water table. Screen Length: Thirty feet of screen, 20 feet of which is below the water table. Ten feet of screen above the water table will allow for groundwater fluctuations during the wet seasons. Well Development: Reversal or surges in flow created either by surge blocks, bailers, or pumps, if bridging of the screen was indicated, if no bridging was indicated, wells were developed using a submersible pump, bladder pump, or bailer. DOCUMENTATION REQUIREMENTS All well design and construction completed during the investigation are documented with the following information: · Date/time of construction; · Drilling method and drilling fluid used; · Well location (+0.5 foot); · Well depth (+0.1 foot); · Drilling and lithologic logs; · Casing material; · Screen material and design; · Casing and screen joint size; · Type of protective cap; · Detailed drawing of well; · Well cap elevation (_+0.5 foot); · Top of casing elevation (_+0.01 foot); · Well development procedures; :lwater Well-Installation and Monitoring Procedures Page 3 · Screen slot size/length; · Filter pack material and size; · Filter pack placement method; · Sealant materials; · Sealant volume; · Sealant placement method; · Surface seal design/construction; · Soil boring diameter and well casing diameter; and · Relative ground surface elevations (_+0.0t foot). WATER LEVEL MEASUREMENTS, Water level measurements were collected from the monitoring well according to the following procedures: · The water level within the well was measured to an accuracy of +0.01 foot using an electric measuring device and referenced to the established datum; and · All measurements were reproduced to assure validity. WELL DEVELOPMENT Well development was conducted by simple pumping if bridging of the screen did not occur. If bridging occurred, well surging may have been necessary for adequate well production. Well surging was created by the use of either surge blocks, bailers, or pumps, whichever was most convenient at the time. Only formation water was used for surging the well if at all possible. If necessary, an outside source of water was used. Well development continued until non turbid groundwater was produced. All purged groundwater was held on site in covered holding barrels until laboratory analysis of the water was received. PURGING PROCEDURES During the purging process, groundwater was constantly monitored for temperature, pH, conductivity, turbidity, odor, and color. These parameters were recorded on a water sample log. Purging continued until all stagnant water within the well had been replaced by fresh formation water (this called for the removal of a minimum of at least 3 to 4 well casing volumes), the above outlined parameters had stabilized, and non-turbid groundwater was being produced. The monitoring well was purged using either a submersible pump, bailer, or bladder pump. A surge block was used if it became apparent during pumping that the well screen had become bridged with sediment or the produced groundwater was overly turbid. ~Groundwater Well Installation and Monitoring Procedures Page 4 Produced groundwater was stored on site in 55-gallon barrels until water sample analytical results were received from the laboratory. SAMPLE COLLECTION PROCEDURES Measurements collected in the field prior to sampling included water level, pH, conductivity, temperature, and turbidity, and were performed in conformance with EPA's publication "A Compendium of Supeffund Field Operations Methods." GROUNDWATER SAMPLE COLLECTION A groundwater sample was collected from the monitoring well. The sample collection procedures are described below. · ' A l-liter, disposable TeflonTM bailer was used to collect the groundwater sample. · Development of the well was accomplished prior to sampling of the well (see "Well Development" section). · Purging of the well was accomplished immediately prior 'to the sampling of the groundwater. Purging con',tinued until the parameters of temperature, conductivity, and/or pH had stabilized and a, minimum of 5 well casing volumes were excavated. Any applicable purging method was allowable to inciude bailing, gas pressure lift systems, submersible pumps, and bladder pumps. However, the use of a gas pressure lift system usually changes the dissolved gas content of the groundwater, pH, conductivity, or other analyses used to determine purge completion were conducted downhole. · Once the well was sufficiently purged, the actual sampling began as soon as the water level began to approach its pre-purged level. If recovery was very slow, it may have been necessary to wait several hours or even until the following day before sufficient volume was available for all the necessary analyses. In this instance, a volatile organics sample was collected. · The groundwater sample was collected in chilled, 40-milliliter VOA vials with TeflonTM-lined caps. Hydrochloric acid preservative was added to all vials by the laboratory to lower sample pH to 2. Samples were held at 4°C while in the field and in transport to the laboratory. Analysis was Performed by Holguin, Fahan & Associates, Inc., Environmental Laboratories, a California state-certified laboratory. HOLGUI ,N~~- ~--] FAHAN ~ & A.~qOCIATES, INC.

The property was recently vacated by its former tenant, Central California Kenworth (Kenworth). SITE DESCRIPTION The subject site is located at 3012 Pierce Road in the city of Bakersfield, Kern County, California. The topography of the site. Is relatively fiat, with a slight fall to the west (see Figure 1). The project site is bound on the west by Pierce Road, on the south by Don Keith Trucking Company, on the east by an Office Depot retail store, and on the north by a Home Base retail store (see Figure 2 - Plot Plan). The property was recently a large truck and bus maintenance facility. Kenworth ceased operations at the site during the first quader of 1994, and has since vacated the facility. BACKGROUND PREVIOUS WORK Kenworth operated a steam wash in a service bay at the property. The floor drain was previously connected to a pipeline that led to a four-chambered septic tank along the southern property line (see Figure 2). On August 25, 1988, representatives of the EPA conducted an inspection of the property to determine whether any practices at the properly presented a ENVIRONMENTAL PLANNERS · S(~IENTISTS · GEOLOGISTS AND ENGINEERS Contaminated Site Assessments * Real Estate Audits * Site Remediation * Hazardous waste Management HOLGUII~, Mr. Dan Stagey ~ FAHAN KCDEHS ~ & PxSSOCAATF_C,, INC. March 2, 1995- Poge 2 ENVIRONMENTAL MANAGEMENT CONSULTANTS threat to groundwater resources. At that time, it was noted that the septic tank system connected to the floor drain warranted further Investigation as a potential Class V shallow disposal well. The Kern County Department of Environmental Health Services (KCDEHS) subsequently received funding through the EPA to conduct a pilot program for local enforcement of Class V shallow disposal wells. On January 8, 1993, a water sample was collected by the KCDEHS from the four-chambered septic tank. Kenworth was instructed to disconnect the piping leading from the floor drain to the septic tank and abandon the septic tank in place by filling it with a cement-sand slurry. Kenworth performed the first task by disconnecting the piping and in'stalling a self-contained, aboveground, washwater recycling system. HFA completed the second task by abandoning the septic tank on August 11, 1998. During the septic tank abandonment, the KCDEHS representative observed the presence of a possible Class V shallow disposal well approximately 25 feet east of the septic tank; an underground, concrete, waste oil vault in the southeastern comer of the property; and a storm water drain approximately 25 feet north of the waste oil vault (see Figure 2). In a letter dated August 17, 1993, the KCDEHS requested that a site Investigation be performed to assess the potential for hydrocarbon-containing soils associated with the dry well, waste oil vault, and storm drain. HFA performed the drilling and sampling on September 14, 1993. Soil bodng B-1 was ddlled adjacent to the western side of the dry well to a total depth of 30 feet below grade (fbg). Soil boring B-2 was drilled adjacent to the northwestern corner of the waste oil vault to a total depth of 25 fbg. Soil bodng B-3 was ddlled through the storm water drain to a total depth of 22.5 fbg (see Figure 2 for soil boring locations). Since groundwater was encountered in soil bodng B-1 at a depth of 28 fbg, the other two soil borings were terminated above this depth. Soil samples collected from the soil borings were tested for a petroleum fingerprint consisting of total petroleum hydrocarbons (TPH) as gasoline; TPH as diesel; TPH as motor o11; TPH as crude oil; benzene, toluene, ethylbenzene, and total xylenes (BTEX); and common solvents using EPA Method 8260. In addition, one sample from each soil boring was tested for the California Title 22 metals. Subsequently, samples of the liquids and sludge within the waste oil vault were collected on September 17, 1993, and analyzed for TPH as gasoline, TPH as diesel, TPH as motor oil, TPH as crude oil, BTEX, and common solvents using EPA Method 8260. These liquid and sludge samples were also tested for TPH as oil and grease using EPA Method 418.1 as well as the California Title 22 metals. Analysis of the soil samples collected from soil boring B-2 (advanced adjacent to the northwestern corner of the waste oll vauff) indicated the presence of hydrocarbon-containing soils at a depth of 10 fbg as indicated by the presence of TPH as motor oll at a concentration of HOLGUIN , Mr: Dan,~tarke¥ ' FAHAN KCDEHS & TES, lNG. March 2, 1995 - Poge 3 ENVII:=IONMENTAL MANAGEMENT CONSULTANTS 410 rog/kg. Concentrations of I'PH, BTEX, and common solvents were not detected in soil borings B-1 and B-3. The California Title 22 metals were detected at concentrations consistent with native concentrations in the area (see Table 1 - Summary of Soil Sample Analytical Results for Drilling). Analysis of liquid and sludge samples collected from the waste oil vault Indicated the presence of hydrocarbon-containing liquids in the form of TPH as oll and grease at a concentration of 7A[X] mg/I. Concentrations of TPH as gasoline, TPH as diesel, BTEX, and common solvents were not detected, with the exception of toluene at a concentration of 0.008 rog/I, 1,2/l-trimethylbenzene at a concentration of 0.0016 mg/I, and naphthalene at a concentration of 0.001 mg/I. Lead was detected at concentrations of 189 rog/kg for total lead in the sludge and 2.2 mg/I for soluble lead (see Table 2 - Summary of Sludge Sample Analytical Results). Therefore, the liquid contents of the waste oil vault required disposal crt one of several approved recycling facilities. After the KCDEHS reviewed HFA's October 11, 1993, site assessment report, it requested in a letter dated October 26, 1993, that the waste oil vault and dry well be abandoned and the associated hydrocarbon-containing soils be excavated. HFA subsequently excavated the soils between February 16, 1994, and March 23, 1994. Approximately 1,300 cubic yards of hydrocarbon-containing soils were excavated from beneath the location of the two waste oil vaults to a depth of 19 fbg, beneath the dry well to a depth of 27 fl)g, and beneath the oil/water separator to a depth of 15 fbg (see Table 3 - Summary of Soil Sample Analytical Results for Excavation). The excavated hydrocarbon-containing soils were then transported to a road materials recycling facility for disposal. Groundwater was observed In the base of the dry well excavation at a depth of 27 fbg. The excavation pits were subsequently bockfllied with import material to surface grade. During the course of the cleaning of the underground, concrete waste oil vault, a second vault,. which was entirely buried, was discovered to the east of the first vault. The two vauffs were connected by an adjoining pipe and contained a significant amount of used oil riflers and rags. The contents of the waste oil vauffs were segregated, containerized, and disposed of at an appropriate recycling facility. Both vaults were cleaned, removed, and properly disposed. During the removal of the dry well, no piping was discovered connecting the dry well to the previously abandoned, four-chambered septic tank. Instead, a pipe was discovered leading to the east, away from the septic tank. The KCDEHS requested that the pipe be exposed and removed. The course of the pipe was discovered to proceed east to the property line, north behind the two waste oil vaults, then northwest to the eastern end of the service bay building. The piping leading to the service bay building was discovered to be the effluent from a previously in-place, abandoned, two-chamber, wooden oil/water separator (see Figure 2). 1HOLGUI~, Mr. Dan Starkey ~ FAHAN KCDEHS ~J & IATES, INC. Mca'ch 2, 1¢?5 -Poge 4 ENVIRONMENTAL MANAGEMENT CONSULTANTS An inlet pipe was observed exiting from the western side of tho wooden oil/water separator leading toward the floor drain of the steam wash. This newly identified system appears to hove been a predecessor of the four-chambered septic tank system. Abandonment of the system was completed by removing the wooden oil/water separator and backfilling the steam wash floor drain with a cement grout. The KCDEHS representative also observed a metal plate, flush with the concrete floor, welded to the top of an 8-Inch-diameter pipe within the westernmost service bay. HFA removed the plate and discovered a 10a-foot-deep water well under the concrete foundation of the service bay. The well was sampled to determine that no hazardous materials were present in the groundwater and subsequently abandoned under permit with the KCDEHS by backfilling with a cement grout. A single soil boring was ddlled on September 20, 1994, to a depth of 50 fbg and was subsequently completed as a groundwater monitoring well MW-1 in the location of the former dry well. The well was constructed with 20 feet of blank schedule 40 PVC well casing from the surface to a depth of 20 fbg and 30 feet of 0.02-inch perforated schedule 40 PVC well casing from a depth of 20 to 50 fbg. On September 27, 1994, and December 5, 1994, representative groundwater samples were collected from on-site monitoring well MW-1 (see Figure 2 for monitoring well location). Before sampling, the monitoring well was checked for an immiscible layer, and none was found. Concentrations of TPH as gasoline, TPH as diesel, TPH as oil and grease, and BTEX were not detected in the groundwater samples with the exception of TPH as oil and grease at a trace concentration of 3 mg/I in the December 5, 1994, sampling event (see Table 4 - Summary of Groundwater Sample Analytical Results]. SITE GEOLOGY The site is located in a relatively flat area at an elevation of approximately 500 feet above mean sea level (MSL). 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 HOLGUI Mr. Dan Starkey FAHAN KCDEHS ~ & ASSOCIATES, INC. March 2, 1995 - Po~e 5 ENVIRONMENTAL MANAGEMENT CONSULTANTS crystalline basement at a depth of approximately 30fl300 fbg. Geologic deposits in the study area Include Pleistocene-age, alluvial sealments of the Kern River Formation, which form a homocllne dipping gently to the southwest. The deposits are alluvium consisting of poorly indurated and dissected fan deposits (California Division of Mines and Geology, 1964). This Is an area at the foot of rolling hills with a maximum elevation of 900 feet above 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 non-marine Kern River Formation, non-marine Chanac Formation, marine Santa Margarita Formation (possibly interfingering with Chanac Formation due to the tentative correlation of a 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, and non-marine Walker Formation. Of these, only the Kern River, Chanac, and Santa Margarita formations are important to the hydrogeology of the site. The Tertiary, non-marine Kern River Formation is unconformably overlain by bouldery terrace deposits of Quaternary Older Alluvium. Two naturally-occurring geologic units ore present In the near surface at the site. The two natural units are the Tertiary (Miocene to Pliocene), non-marine Kern River Formation and the Quaternary (Pleistocene), Older Alluvium. The Older Alluvium forms a thin terrace deposit lying unconformably on the Kern River Formation. 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 0.5 mile north of the Kern River. The depth to the regional unconfined aquifer has been measured at approximately 50 fbg beneath the site with the direction of groundwater flow to the west-northwest (Kern County Water Agency (KCWA), 1992 Report on Water Conditions, Improvement District ,94, February 1993). However, due to the significant amount of precipitation during the winter of 1993, and the ongoing use of excess surface waters by the KCWA in nearby groundwater recharge basins, groundwater was observed by HFA at a 'HOLGUI Mr. Dan Starkey FAHAN KCDEHS & ASSOCIATES, INC. March 2, 1995- Poge 6 ENVIRONMENTAL MANAGEMENT CONSULTANTS depth of 28 fbg during the September 1993, soils investigation; at a depth of..'.27~fbg;during the March 1994, soils excavation; and at a depth of 29 fbg during the current groundwater assessment. MONITORING METHODS On February 3, 1995, a representative groundwater sample was collected from on-site monitoring well MW-1 (see Figure 2 for the monitoring well location). Prior to sampling, the monitoring well was checked for an immiSCible layer, and none was found. The well was then purged prior to extracting a sample representative of the In-sltu groundwater. During the purging process, the conductivity, temperature, and pH of the groundwater were monitored and recorded on a water sample log. Purging continued until 5 casing volumes were produced and the measured parameters were at a relatively stable state. The groundwater sample was collected after the well had recharged to greater than 80 percent of its Initial static water level (see Attachment 1 for the groundwater monitoring procedures and Attachment 2 for the water sample log). A disposable TeflonTM bailer was used to Sample monitoring well MW-1. The sample collected for analyses of TPH as gasoline, TPH as diesel, TPH as oil and grease, and BTEX was placed in a chilled, volatile organic analysis vial containing hydrochloric acid as a preservative. The sample was labeled, sealed, and recorded on a chain-of-custody record in accordance with the procedures outlined in the KCDEHS guidance document. The groundwater sample contained no visible suspended matter, and no headspace was observed in the container. The sample was placed in a container filled with Blue-IceTM for cooling purposes and was transported to HFA Environmental Laboratories, a California state-certified laboratory, for analysis (see Attachment 1 for the groundwater monitoring procedures). ANALYTICAL RESULTS OF GROUNDWATER SAMPLES The groundwater sample collected from monitoring well MW-1 was analyzed for concentrations of TPH as gasoline and TPH as diesel using the DHS-TPH Method, TPH as oil and grease using EPA Method 418.1, and BTEX using EPA Method 602. Concentrations of TPH as gasoline, TPH as diesel, TPH as oil and grease, and BTEX were not detected in the groundwater sample (see Table 4 and Attachment 3 for the laboratory report). KCDEHS & INC. March 2. 1995- Page 7 ENVIRONMENTAL MANAGEMENT CONSULTANTS After three consecutive quarters of groundwater sampling wherein TPH as gasoline, TPH as diesel, TPH as oil and grease, and BTEX were not detected with the exception of the detection of a trace concentration of TPH as oil and grease in a single monitoring event (fourth quarter 1994), Inland Industries, Inc., requests that the KCDEHS consider the site for a No Further Action (NFA) determination and permit the abandonment of the monitoring well. ACTIVITIES PLANNED FOR THE REMAINDER OF THE FIRST QUARTER OF 1995 If the KCDEHS concurs with an NFA determination for the Inland Industries, Ltd., property, the following activity will be completed during the remainder of the first quarter of 1995: · abandonment of the groundwater monitoring well under permit with the KCDEHS.

GROUNDWATER MONITORING PROCEDURES GROUNDWATER MONITORING ~ROCEDURES WATER LEVEL MEASUREMENTS Water level measurements were collected from the monitoring well according to the following procedures: · The water level within the well was measured to an accuracy of ~-0.01 foot using an electric measuring device and referenced to the established datum; and · All measurements were reproduced to assure validity. PURGING PROCEDURES During the purging process, groundwater was constantly monitored for temperature, pH, conductivity, turbidity, odor, and color. These parameters were recorded on a water sample Icg. Purging continued until all stagnant water within the well hod been replaced by fresh formation water (,his coiled for the removal of o minimum of at leas, 3 to 4 well casing volumes>, the above outlined parameters hod stobUized, and non-turbid groundwater was being produced. The monitoring well was purged using either a submersible pump, bailer, or bladder pump. A surge block was used if it became apparent during pumping that the well screen had become bridged with sediment or the produced groundwater was overly turbid. Produced groundwater was stored on site in 55-gallon barrels until water sample analytical results were received from the laboraton/. SAMPLE COLLECTION PROCEDURES Measurements collected in the field prior to sampling included water level, pH, conductivity, temperature, and turbidity, and were performed In conformance with EPA"s publication "A Compendium of Superfund Field Operations Methods." GROUNDWATER SAMPLE COLLECTION A groundwater sample was collected from the monitoring well. The sample collection procedures are described below. · A l-liter, disposable TeflonTM bailer was used to collect the groundwater sample. ·. Development of the well was accomplished prior to sampling of the well. Groui~water Monitoring Procedures. Page2 · Purging of the well was accomplished immediately prior to th® sampling of the groundwater. Purging continued until the parameters of temperature, conductivity° and/or pH had stabilized and a minimum of 5 well casing volumes were excavated. Any applicable purging method was allowable to Include bailing, gas pressure lift systems, submersible pumps, and bladder pumps. However, the use of a gas pressure lift system usually changes the dissolved gas content of the groundwater, pH, conductivily0 or other analyses used to determine purge completion were conducted downhole. · Once the well was sufficiently purged, the actual sampling began as soon as the water level began to approach its pre-purged level. If recovery was very slow, it may have been necessary to wait several hours or even until the following day before sufficient volume was available for all the necessary analyses. In this Instance, a volatile organics sample was collected. · The groundwater sample was collected In chilled, 40-milliliter VOA vials with Teflonm-Iined caps. Hydrochloric acid preservative was added to all vials by the laboratory to lower sample pH to 2. Samples were held at 4°C while in the field and in transport to the laboratory.

GROUNDWATER WELL INSTALLATION AND MONITORING PROCEDURES GROUNDWATER WELL INSTALLATION AND MONITORING PROCEDURES The objectives of the drilling program were to: 1. Characterize the geology and hydrogeology of the site during well installation; 2. Determine whether any soil contamination was present during soil boring installation; and 3. Adequately construct the monitoring well to provide all necessary samples and data required. SITING The monitoring well was positioned as noted in the report. DRILLING PROCEDURES The soil boring for installation of the monitoring well was drilled with an 8-inch outside diameter, hollow-stem, flight auger to a depth of 20 feet below the top of the water table. Cuttings from the soil boring were logged by an experienced environmental geologist under the supervision of a State of California Registered Geologist. The soil was classified according to the standard Unified Soil Classification System. Observations regarding the types and quantities of waste materials encountered and any photoionization detector readings were logged. All data collected during the drilling of the boring was recorded on individual soil boring logs. CONSTRUCTION MATERIALS The monitoring well was constructed of 2-inch PVC casing with the blank casing extending from grade to 10 feet above the top of the groundwater. Slotted casing extends from 10 feet above to 20 feet below the top of the groundwater. The well was designed in accordance with Department of Health Services and State Water Resources Control Board guidance manuals. The specifications are listed in the table on the following page. e~Groundwater Well:Installation and Monitoring Procedures Page 2 MONITORING WELL SPECIFICATIONS Casing Size: Two-inch inside diameter. Casing Materials: Schedule 40 PVC. Filter Pack: Washed Monterey sand extending no more than 3 feet above the well screen. Sealant: Three feet of sodium bentonite immediately over the filter pack. Cement and bentonite mixture used as annular sealant from the top of the bentonite seal to the ground surface (2 to 5 percent bentonite by weight). Well Covers: Twelve-inch diameter locking aluminum access covers. Well Intake: Twenty feet of 0.02-inch slotted casing below the water table. Screen Length: Thirty feet of screen, 20 feet of which is below the water table. Ten feet of screen above the water table will allow for groundwater fluctuations in the wet seasons. Well Development: Reversal or surges in flow created either by surge blocks, bailers, or pumps, if bridging of the screen was indicated. If no bridging was indicated, wells were developed using a submersible pump, bladder pump, or bailer. DOCUMENTATION REQUIREMENTS All well design and construction completed during the investigation are documented with the following information: · Date/time of construction: · Drilling method and drilling fluid used; · Well location (_+0.5 feet); · Well depth (+0.1 foot); · Drilling and lithologic logs; · Casing material; · Screen material and design; · Casing and screen joint size; · Type of protective cap; · Detailed drawing of well; · Well cap elevation (+0.5 feet); · Top of casing elevation (+0.01 foot); · Well development procedures; eGrounclwater Well, Installation, and Monitoring Procedures Page 3 · Screen slot size/length; · Filter pack material and size; · Filter pack placement method; · Sealant materials; · Sealant volume; · Sealant placement method; · Surface seal design/construction; · Borehole diameter and well casing diameter; and · Relative ground surface elevations (_+0.01 foot). WATER LEVEL MEASUREMENTS Water level measurements were collected from the monitoring well according to the following procedures: · The water level within the well was measured to an accuracy of_+0.01 foot using an electric measuring device and referenced to the established datum; and · All measurements were reproduced to assure validity. WELL DEVELOPMENT Well development was conducted by simple pumping if bridging of the screen did not occur. If bridging occurred, well surging may have been necessary for adequate well production. Well surging was created by the use of either surge blocks, bailers, or pumps, whichever was most convenient at the time. Only formation water was used for surging the well if at all possible. if necessary, an outside source of water was used. Well development continued until non turbid groundwater was produced. All purged groundwater was held on site in covered holding barrels until laboratory analysis of the water was received. PURGING PROCEDURES During the purging process, groundwater was constantly monitored for temperature, pH, conductivity, turbidity, odor, and color. These parameters were recorded on a water sample Icg. Purging continued until all stagnant water within the well had been replaced by fresh formation water (this called for removal of a minimum of at least three to four well casing volumes), the above outlined parameters had stabilized, and non-turbid groundwater was being produced. The monitoring well was purged using either a submersible pump, bailer, or bladder pump. A surge block was used if it became apparent during pumping that the well screen had become bridged with sediment or the produced groundwater was overly turbid. eGroundwater Well:Installation and Monitoring Procedures Page 4 Produced groundwater was stored on site in 55-gallon barrels until water sample analysis was received from the laboratory. SAMPLE COLLECTION PROCEDURES Measurements collected in the field prior to sampling included water level, pH, conductivity, temperature, and turbidity, and were performed in conformance with EPA's publication "A Compendium of Superfund Field Operations Methods." GROUNDWATER SAMPLE COLLECTION A groundwater sample was collected from the monitoring well. The sample collection procedures are described below. · A l-liter, disposable TeflonTM bailer was used to collect groundwater samples. · Development of the well was accomplished prior to .sampling of the well (see "Well Development" section). · Purging of the well was accomplished immediately prior to sampling of the groundwater. Purging continued until the parameters of temperature, conductivity, and/or pH stabilized and a minimum of five well casing volumes were excavated. Any applicable purging method was allowable to include bailing, gas pressure lift systems, submersible pumps, and bladder pumps. However, if a gas pressure lift system was used, as this method usually changes the dissolved gas content of the groundwater, pH, conductivity, or other analyses used to determine purge completion were conducted down hole. · Once the well was sufficiently purged, the actual sampling began as soon as the water level began to approach its pre-purged level. If recovery was very slow, it may have been necessary to wait several hours or even until the. following day before sufficient volume was available for all the necessary analyses. In this instance, a volatile organics sample was collected. · Groundwater samples were collected in chilled 40-milliliter VOA vials with TeflonTM lined caps. Hydrochloric acid preservative was added to all vials by the laboratory to lower sample pH to two. Samples Were held at 4°C while in the field and in transport to the laboratory. Analysis was performed by HFA's California state-certified laboratory. ENVIRONMENTAL MANAGEMENT CONSULTANTS ATTACHMENT 2.

PROPERTY, 3012 PIERCE ROAD, BAKERSFIELD, CALIFORNIA Dear Ms. Darling: Holguin, Fahan & Associates, Inc., (HFA) is pleased to present the following preliminary groundwater assessment report for the Inland Industries, Ltd., property located at 3012 Pierce ROad in the city of Bakersfield, Kern County, California (see Figure 1 - Site Location Map). The property was recently vacated by its former tenant, Central California Kenworth (Kenworth). SITE DESCRIPTION The site is located at 3012 Pierce Road in the city of Bakersfield in Kern County, California (see Figure 1). The project site is bound on the west by Pierce Road; on the south by Don Keith Trucking Company; on the east by an Office Depot retail store; and on the north by a Home Base retail store (see Figure 2 - Plot Plan). The topography of the site is relatively flat, with a slight fall to the west. The property was recently operated as a large truck and bus maintenance facility. However, Kenworth ceased operations at the site during the first quarter of 1994, and has since vacated the facility. BACKGROUND PREVIOUS WORK Kenworth operated a steam wash in a service bay at the property. The floor drain was formerly connected to a pipeline that led to a four-chambered septic tank along the southern property line (see Figure 2). On August 25, 1988, representatives of the EPA conducted an inspection of the property to determine whether any practices at the property presented a threat to ENVIRONMENTAL PLANNERS.. · S(CIENTtSTS · GEOLOGISTS AND ENGINEERS Contaminated Site Assessment~eal Estate Audits · Site Remediation * lrdous Waste. Management HOLGUIN, Ms?Flora:Darling FAHAN KCDEHS ~ &~TES, INC. November2, 1994 - Page 2 ENVIRONMENTAL MANAGEMENT CONSULTANTS 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. The Kern County Depadment of Environmental Health Services (KCDEHS) subsequently received funding through the EPA to conduct a pilot program for local enforcement of Class V shallow disposal wells. On January 8, 1993, a water sample was collected by the KCDEHS from the four-chambered septic tank. Kenwodh was instructed to disconnect .the piping leading from the floor drain to the septic tank and to abandon the septic tank in place by filling it with a cement-sand slurry. Kenwodh performed the first task by disconnecting the piping'and installing a self-contained, aboveground, wash water recycling system. HFA completed the second task of septic tank abandonment on August 11, 1993. During the septic tank abandonment, the KCDEHS representative observed the presence of a possible Class V shallow disposal well approximately 25 feet east of the septic tank; an underground, concrete, waste oil vault in the southeastern corner of the property; and a storm water drain approximately 25 feet nodh of the waste oil vault (see Figure 2). In a letter dated August 17, 1993, the KCDEHS requested that a site investigation be performed to assess the potential for hydrocarbon-containing soils associated with the dry well, waste vault, and storm drain. HFA performed the drilling and sampling on September 14, 1993. Soil boring B-1 was drilled adjacent to the western side of the dry well to a total depth of 30 feet below grade (fbg). Soil boring B-2 was drilled adjacent to the nodhwestern corner of the waste oil vault to a total depth of 25 fbg. Soil boring B-3 was drilledthrough the storm water drain to a total depth of 22.5 fbg (see Figure 2 for soil boring locations). Since groundwater was encountered in soil boring B-1 at a depth of 28 fbg, the other two soil borings were terminated above this depth. Soil samples from the borings were tested for a petroleum fingerprint consisting of total petroleum hydrocarbons (TPH) as gasoline, diesel, motor oil, and crude oil; benzene, toluene, ethylbenzene, and total xylenes (BTEX); and common solvents using EPA Method 8260. In addition, one sample from each soil boring was tested for the California Title 22 metals. Subsequently, samples of the liquids and sludge within the 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. These liquid and sludge samples were also tested for TPH as oil and grease using EPA Method 418.1, and the California Title 22 metals. Analysis of soil samples collected from soil boring B-2 (advanced adjacent to the nodhwestern corner of the waste oil vault) indicated hydrocarbon-containing soils at a depth of 10 fbg as indicated by the presence of TPH as motor oil at a concentration of 410 mg/kg. Concentrations of TPH, BTEX, and common solvents were not detected in soil borings B-1 and B-3. The & ASSOCIATES, INC. Novem~r 2,.1~4: Page: 3 ENVIRONMENTAL MANAGEMENT CONSULTANTS California Title 22 metals were detected at concentrations consistent with native concentrations in the area (see Table 1 - Summary of Soil Sample Analytical Results). Analysis of liquid and sludge samples collected from the waste oil vault indicated hydrocarbon-containing liquids as indicated by the presence of TPH as oil and grease at a concentration of 7,400 mg/I. Concentrations of TPH as gasoline, TPH as diesel, BTEX, and common solvents were not detected, with the exception of toluene at a concentration of 0.008 mg/I, 1,2,4-trimethylbenzene at a concentration of 0.0016 mg/I, and naphthalene at a concentration of 0.001 mg/I. Lead was detected at concentrations of 189 mg/kg for total lead in the sludge, and 2.2 mg/I for soluble, lead. Therefore, the liquid contents of the waste oil Vault required disposal at one of several approved recycling facilities (see Table 2 - Summary of Sludge Sample Analytical Results). The KCDEHS reviewed HFA's October 11, 1993, site assessment report and requested in a letter dated October 26, 1993, that the waste oil vault and dry well be abandoned, and that the associated hydrocarbon-containing soils be excavated. HFA subsequently excavated the soils between the dates of February 16, 1994, and March 23, 1994. Approximately 1,300 cubic yards of hydrocarbon-containing soils were excavated from beneath the location of the two waste oil vaults to a depth of 19 fbg, beneath the dry well to a depth of 27 fbg, and beneath the oil/water separator to a depth of 15 fbg (see Table 3 - Summary of Soil Sample Analytical Results). The excavated hydrocarbon-containing soils were then transported to a road materials recycling facility for disposal. Groundwater was observed in the base of the dry well excavation at a depth of 27 fbg. The excavation pits were subsequently backfilled with import material to surface grade. During the course of the cleaning of the underground concrete waste oil vault, a second vault, which was entirely buried, was discovered to the east of the first vault. The two vaults were connected by an adjoining pipe, and contained a significant amount of used oil filters and rags. These were segregated, containerized, and disposed of at an appropriate recycling facility. Both vaults were cleaned, removed, and properly disposed. During the removal of the dry well, no piping was discovered connecting the dry well to the previously abandoned four-chambered septic tank. Instead, a pipe Was discovered leading to the east, away from the septic tank. The KCDEHS requested that the pipe be exposed and removed. The course of the pipe was discovered to proceed east to the property line, north behind the two waste oil vaults, then nodhwest to the eastern end of the service bay building. However, this end was discovered to be the effluent from a previously in-place abandoned two-chamber, wooden oil/water separator (see Figure 2). ~ & ~_.q.~OCJ~T~, INC. Novembor 2; 1~4- Poge 4 ENVIRONMENTAL MANAGEMENT CONSULTANTS An inlet pipe was observed exiting from the western side of the wooden oil/water separator toward the floor drain of the steam wash. This newly identified system appears to have been a predecessor of the four-chambered septic tank system. Abandonment of the system was completed by removing the wooden oil/water separator and backfilling the steam wash floor drain with a cement grout. The KCDEHS representative also observed a metal plate, flush with the concrete floor, welded to the top of an 8-inch diameter pipe within the westernmost service bay. HFA removed the plate and discovered a 100-foot-deep water well under the concrete foundation of the seivice bay. The well was sampled to determine that no hazardous materials were present in the groundwater, and was subsequently abandoned under permit with the KCDEHS by backfilling with a cement grout. SITE GEOLOGY The site is located in a relatively flat area at an elevation of approximately 500 feet above mean sea level (MSL). The site is located in the southern part of the Great Valley Geomorphic Province. The Great Valley is a nodh-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 a depth of approximately 30,000 fbg. 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 Division of Mines and Geology, 1964). This is an area at the foot of rolling hills with a maximum elevation of 900 feet above 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. & A.&SOCIATES, INC. November2; lgg ;;Page';5 ENVIRONMENTAL MANAGEMENT CONSULTANTS ' In the region of the site, the Tediary sedimentary sequence, from top to bottom, is non-marine Kern River Formation, non-marine Chanac Formation, marine Santa Margarita Formation (possibly interfingering with Chanac Formation due to the tentative correlation of a 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, and non-marine Walker Formation. Of these, only the Kern River Formation, Chanac, and Santa Margarita are important to the hydrogeology of the site. The Tertiary non-marine Kern River Formation is unconformably overlain by bouldery terrace deposits of 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), non-marine Kern River Formation, and the Quaternary (Pleistocene), Older Alluvium. The Older Alluvium fOrms a thin terrace deposit lying unconformably on the Kern River Formation. 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 1/2 mile north of the Kern River. The depth to the regional unconfined aquifer has been measured at approximately 50 fbg beneath the site with the direction of groundwater flow to the west-northwest (Kern County Water Agency (KCWA), 1992 Report on Water Conditions, Improvement District #4, February 1993). However, due to the significant amount of precipitation during the winter of 1993, and the ongoing use of excess surface waters by the KCWA in nearby groundwater recharge basins, groundwater was observed by HFA at a depth of 28 fbg during the September 1993 soils investigation, at a depth of 27 fbg during the March 1994 soils excavation, and at a depth of 29 fbg during the current groundwater assessment activities. WELL INSTALLATION AND MONITORING METHODS The intent of this phase of remedial action was to install and sample a single groundwater well positioned in the location of the former dry well. A single soil boring was drilled on~r 20,. 1994;to a depth of 50 fbg and, subsequently was completed as a groundwater monitoring well. The well was constructed with 20 feet of blank schedule 40 PVC well casing from the surface to a depth of 2[] fbg and 30 feet of 0.02-inch I"' F,,a- N ': '; '':~ .f MS[; F!0ra:~.'D~flihg~' ,, KCDEHS~' -'~"~a~'~l & ASSOC~TF_~, INC. Novembor 2. 1994 - Page 6 ENVII~IONMENTAL MANAGEMENT CONSULTANTS perforated schedule 40 PVC from a depth of 20 to 50 fbg (see Attachment 1 for groundwater well installation and monitoring procedures, Attachment 2 for the monitorir)g well construction details, and Attachment 3 for a copy of the KCDEHS groundwater monitoring well installation permit). On September 27, 1994, a representative groundwater sample was collected from on-site monitoring well MW-1 (see Figure 2 for monitoring well location). Before sampling; the monitoring well was checked for an immiscible layer, and none was found. The well was then purged prior to extracting a sample representative of the in-situ groundwater. During the purging process, the conductivity, temperature, and pH of the groundwater was monitored and recorded on a groundwater sample log. Purging continued until 5 casing volumes were produced and the measured parameters were at a relatively stable state. The groundwater sample was collected after the well had recharged to greater than 80 percent of its initial static water level (see Attachment 4 for the water sample log). A disposable TeflonTM bailer was used to sample the well. The sample collected for TPH as oil and grease and BTEX analyses was placed in a chilled, volatile organic analysis vial containing hydrochloric acid as a preservative. The sample was labeled,' sealed, and recorded on a chain-of-custody record in accordance with the procedures outlined in the KCDEHS guidance document. The groundwater sample contained no visible suspended matter, and no headspace was observed in the container. The sample was placed in a container filled with Blue-IceTM for cooling purposes and was transported to HFA's California state-certified laboratory for analysis (see Attachment 1 for the groundwater sample collection procedures). ANALYTICAL RESULTS OF GROUNDWATER SAMPLES The groundwater sample collected from well MW-1 was analyzed for concentrations of TPH as gasoline and TPH as diesel using DHS-TPH Method; TPH as oil and grease using EPA Method 418.1; and BTEX using EPA Method 602. No TPH or BTEX concentrations were detected in the groundwater sample (see Table 4 - Summary of Groundwater Sample Analytical Results and Attachment 5 for the laboratory report). FAHAN & INC. Novem~r 2, 1~4 - Page ENVIRONMENTAL MANAGEMENT CONSULTANTS ACTIVITIES PLANNED FOR THE FOURTH QUARTER OF 1994 The following activities will be completed during the foudh quarter of 1994: · groundwater monitoring and sampling will be conducted dudng the fourth quaffer of 1994. In accordance with the KCDEHS request for 1 year of groundwater well monitoring, if the three subsequent monitoring events also do not detect petroleum hydrocarbons in the groundwater, HFA will request on behalf of the property owner, Inland Industries, Inc., that the KCDEHS concur with a NFA determination for the subject site and permit the abandonment of the monitoring well.

TOPOGRAPHY, GEOLOGY, AND HYDROGEOLOGY: The site is located in a relatively flat area at an elevation of approximately 500 feet above mean sea level (MSL). 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 below ground level (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 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 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 non-marine Kern River Formation, non-marine Chanac Formation, marine Santa Margarita Formation (possibly interfingering with Chanac Formation due to the tentative correlation of a 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, non-marine Walker Formation. Of these, only the Kern River Formation, Chanac, and Santa Margarita are important to the hydrogeology of the site. The Tertiary non-marine Kern River Formation is unconformably overlain by bouldery terrace deposits of 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) non-marine Kern River Formation, and Quaternary (Pleistocene) Older Alluvium. The Older Alluvium forms a thin terrace deposit lying unconformably on the Kern River Formation. HOLGUIN , FAHAN Inland Kenworth & ASSOCIATES, INC: Bakersfield, California ENVIRONMENTAL MANAGEMENT CONSULTANTS January 26. i ~4 - Page 3 ©uotemory Older Alluvium is middle to lower Pleistocene age (Qoa2 of Bartow, 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 50 cm 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 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 20 cm in diameter. 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. Chanoc 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 adjoining property indicate that the alluvium is characterized by unconsolidated, moderate to good permeability, silty sand to a depth of approximately 7 feet 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 1/2 mile north of the Kern River. The depth to the regional unconfined aquifer is approximately 50 feet BGL 'HOLGUIN , FAHAN Inland Kenworth &ASSOCIATe, INC. Bakersfield, California ENVIRONMENTAL MANAGEMENT CONSULTANTS January 26, 1994 - Page 4 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 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). 4. PREVIOUS WORK: Inland Kenworth operates a steam wash in a service bay at the property. The floor drain formerly connected to a pipeline that led to four septic tanks along the southern property line (see Figure 2 - Plot Plan). On August 25, 1988, representatives of the Environmental Protection Agency (EPA) 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. The KCDEHS subsequently received funding through the EPA to conduct a pilot program for local enforcement of Class V shallow disposal wells. On January 8, 1993, a water sample was collected by the KCDEHS from the septic tanks. The sample was analyzed for total petroleum hydrocar'bons (TPH) as gasoline, diesel, and oil and grease; volatile organics; and the California Title 22 metals. The KCDEHS reviewed the analytical data and determined that EPA standards had not been exceeded. Inland 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 them with a cement-sand slurry. Inland Kenworth performed the first task by disconnecting the piping. HFA completed the second task of septic tank abandonment on August 11, 1993. The septic tanks were abandoned by HFA on August 11, 1993, and the following tasks were performed: · the surface lids of the septic tanks were exposed and removed; · a vacuum truck removed any remaining liquid within the septic tanks; · a plug was placed in the inlet piping from the floor drain to the first septic tank; · the septic tanks were pressure washed to remove any residual substances from the walls of the tanks; · the vacuum truck removed the rinsate from the septic tanks; · the septic tanks were filled with a five-sack, cement-sand slurry to within 1 foot of the top of the necks; FAHAN Inland Kenworth & tSSOClhTFS, INC. Bakersfield, California ENVIRONMENTAL MANAGEMENT CONSULTANTS Janualy 26, 1994 - Page fi · a neat cement grout was used to fill the remaining 1 foot to the top of the tanks with the top surface domed to cause water to flow away from the tanks; and · the vacuum truck transported the liquid from inside the tanks to Gibson Environmental, Inc.'s (Gibson Environmental's) Bakersfield facility where the liquid will be disposed of. During the septic tank abandonment at the property, the KCDEHS 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, and a storm water drain in' the southeastern corner of the property (see Figure 2). The KCDEHS requested in a letter dated August 17, 1993, that a site investigation be performed to assess whether the former operation of these features has resulted in a release of hazardous materials to the subsurface. The objective 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. HFA performed the drilling and sampling on September 14, 1993, using a Mobile B-53 drill rig operated by Melton Drilling Company of Bakersfield, California. Borehole B-1 was drilled adjacent 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. Borelnole B-3 was drilled through the storm water drain to a total depth of 22.5 feet BGL (see Figure 2). Soils encountered white 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. Groundwater was encountered in borehole B-1 at a depth o~ 28 Ceet BGL; theretore, the other two boreholes were terminated above this depth. Undisturbed soil samples were collected at 5-foot intervals and selectively tested for a petroleum fingerprint consisting of TPH as gasoline, diesel, motor oil, and crude oil; benzene, toluene, ethylbenzene, and total xylenes (BTEX); and common solvents using EPA Method 8260, as well as one sample from each borehole for the California Title 22 metals. In addition, samples of the liquids 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 using EPA Method 418.1; and the California Title 22 metals. FAHAN Inland Kenworth 8, ASSOCIATES, INC. Bakersfield, California ENVIRONMENTAL MANAGEMENT CONSULTANTS January 26, 1994 - Page 6 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 of 10 feet BGL as indicated by TPH as motor oil at a concentration of 410 mg/kg. 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 (see Attachment 1, Table 1.1 for a summary of the laboratory analysis results). Analysis of liquid and sludge samples collected from the eastern waste oil vault showed hydrocarbon-containing liquids as indicated by TPH as oil and grease at a concentration of 7,400 mg/I. TPH as gasoline and diesel, BTEX, and common solvents were not detected, with the exception of toluene at a concentration of 0. ,CK]8 rog/I, 1,2,4-trimethylbenzene at a concentration of 0.0016 mg/I, and naphthalene at a concentration of 0.001 mg/I. Lead was detected at concentrations of 189 mg/kg for total lead in the sludge, and 2.2 mg/I for soluble lead. Therefore, the liquid contents of the waste oil vault will require disposal at one of several approved recycling facilities (see Attachment 1, Table 1.2, for a summary of the laboratory analysis results). The KCDEHS reviewed HFA's October 11, 1993, site assessment report and requested in a letter dated October 26, 1993, that the two waste oil vaults be abandoned under permit and that the hydrocarbon-containing soils associated with the eastern waste oil vault be excavated and disposed of off site at an approved road-base materials recycling facility. The KCRMA-DEHS is requiring removal of the eastern vault, while the western vault may be abandoned in place by filling with a concrete grout. HFA recommends that the two waste oil vaults be abandoned and that the hydrocarbon-containing soils associated with the eastern waste oil vault be excavated and disposed of off-site at one of several approved road base materials recycling facilities. 5. PROCEDURES FOR WASTE OIL VAULT ABANDONMENT: The waste oil vaults will be abandoned by performing the following tasks: 1. The surface lids of the vaults will be exposed and removed. 2. A vacuum truck will remove any remaining liquid within the vaults. HOLGUIi . FAHAN n ond Kenworth · & ASSOCIATe, INC.
