These activities included the removal of five underground storage tanks (USTs) and two oil/water separators (OWSs); evaluation, sampling, and removal of impacted subsurface soil within the respective excavations; characterization, removal, and off-site disposal of residual fluids from the USTs and OWSs, and water; and backfilling excavations to grade and restoring the site surface. The UST and OWS systems which were removed were located in the area between the main shop/office building and the chassis dynamometer building (Figure 2). The systems consisted of the following components.' UST Basin · A 1,000-gallon steel lube oil UST (UST 1) located at the southwest corner of the main building. · A 1,000-gallon steel diesel UST (UST 2) located approximately 1 foot east of the lube oil UST. · A 1,000-gallon steel gasoline UST (UST 3) located approximately 1 foot east of the diesel UST. · A 550-gallon steel mineral spirit UST (UST 4) located approximately 1 foot east of the gasoline UST. · Two dispensers and underground piping associated with the lube oil, diesel, gasoline and mineral spirit USTs, located adjacent the outer south wall of the main building. · A 660-gallon steel used-oil UST (UST 5) located approximately 15 feet south of the used-oil filter drain. OWS System · A westward concrete 2,500-gallon OWS, located underground between the main building and the chassis dynamometer building. · An eastward concrete 2,000-gallon OWS located underground approximately 1 foot west of the used-oil UST. SECOR subcontracted the UST/OWS activities with Kern Environmental Service (KES) of Bakersfield, California. Clogure activities were conducted in accordance with guidelines established by the Bakersfield Fire Department (BFD), the California Regional Water Quality Control Board (RWQCB, 1990), and the Conditions Assessment Plan (CAP) dated May 24, 1995 (SECOR, 1995). The CAP was approved by Mr. Howard Wines of the Bakersfield Fire Department (BFD) on June 30, 1995. January 5, 1996 (DRAFT) SECOR International Incorporated 1 2.0 BACKGROUND 2.1 Site Location and Description The site is located in an industrial/residential area east of Union Avenue, at 301 East 4th Street, in the city of Bakersfield. The subject property is bordered by East 4th Street to the north, Wood Street to the west, and unimproved vacant lots to the south and east. During active operations, the site functioned as an engine repair and maintenance facility since at least 1958. Storage and wastewater treatment systems consisted of an underground storage tank (UST) basin, and an oil/water separator (OWS) system. The UST basin, consisting of the five USTs, was present on the subject property and located adjacent to the sotithwest building corner. The five USTs included a 550-gallon mineral spirits UST installed in 1984, a pre-1984 1,000-gallon diesel fuel UST (connected to the engine dynamometer), a pre-1984 1,000-gallon lubricating oil UST, a 1,000-gallon gasoline UST installed in 1985, and a 660-gallon used oil UST of unknown date. No reports or other evidence which would indicate the presence of additional USTs were discovered during SECOR's September 21, 1994 inspection and associated PSA. The OWS system, located on the western side of the main building, consisted of an eastward and westward separator. Initially, the eastward OWS served to clarify water discharged on site. At a later undetermined date, the westward OWS was constructed and connected to the eastward OWS to increase OWS capacity. 2.2 Regional Physiographic Conditions The subject property is situated at an elevation of approximately 405 feet above mean sea level (MSL). The topography in the vicinity of the subject site is generally flat, while the regional topography slopes to the south. The nearest surface water body to the site is the East Side Canal, located approximately 0.75 miles to the north (USGS, 1975). The average annual precipitation for the Bakersfield area, as measured at Meadows Field, is 5.74 inches (KCWA, 1995). 2.3 Regional Geology The site is located within the San Joaquin Valley, which constitutes the southern portion of the Great Valley geomorphic province. The Great Valley is a topographic and structural basin bounded on the east by the Sierra Nevada, a fault block dipping gently southwestward, and on the west by the Coast Range. The Sierra Nevada is composed of igneous and metamorphic rocks of pre-Tertiary age, which comprise the basement complex beneath the Valley. The Coast Range contains folded and faulted sedimentary rocks of Mesozoic and Cenozoic age, which are similar to the rocks that immediately underlie the Valley and noncomformably overlie the basement complex. In the Bakersfield area, the basement rocks are overlain by early to middle Tertiary age marine sedimentary rocks. The marine sediments are subsequently overlain by poorly consolidated, continental sediments that typically contain the regional groundwater reservoir. The continental sediments consist of alluvial fan and lacustrine deposits and reach an average depth of 2,000 feet below ground surface (bgs) in the study area. 2.4 Site Geology Based on stratigraphic conditions observed during CAP fieldwork, the site is underlain by silt, fine- grained sand, and silt-sand-clay mixtures With occasional clay lenses from the surface to approximately January 5, 1996 (DRAFT) SECOR International Incorporated 2 45 feet bgs. A deposit of clay and clayey silt/clayey sand mixtures, ranging from 5 to 10 feet in thickness, was encountered beneath the surficial alluvial deposits from approximately 45 to 55 feet bgs. Fine-grained to very fine-grained sand was encountered from approximately 55 to 75 feet bgs, the deepest borehole completion depth on site. No groundwater was detected in the soil borings. A summary of the site geology is illustrated as generalized geologic cross-sections in Figures 4 and 5. 2.5 Regional Hydrogeology The property is located in the San Joaquin Basin Hydrologic Study Area, which includes roughly two- thirds of the Great Valley. Within that area, a total of 39 groundwater basins and areas of potential storage have been identified. The inventory covers thirteen groundwater basins which have been identified as significant groundwater sources. The subject property is located within the Kern County groundwater basin. The Kern River flows in a southwesterly direction through Bakersfield and provides significant recharge to the area groundwater system. Water-bearing sediments beneath the site consist of late Tertiary and Quaternary age sand and gravel deposits derived from the Sierra Nevada Range. Regionally, these sediments are divided into upper and lower water bearing zones by an aquitard contemporaneous with the Corcoran Clay Formation. Water well data in the area suggests that a Corcoran Clay equivalent aquitard does not underlie the site (Dale, 1966) and the depth to regional unconfined groundwater beneath the site is estimated at 230 feet bgs. Data also suggests that the site is situated within a regional groundwater depression. As a result, regional groundwater flow direction is interpreted as being towards Bakersfield, and hence the subject property, from all directions (KCWA, 1994). 3.0 PREVIOUS INVESTIGATIONS Previous investigations at the site have included a 1994 Preliminary Site Assessment (PSA), a February 1995 Corrective Action Plan (CAP) investigation, and an additional soil boring investigation conducted in July 1995. The CAP field investigation was performed in February 1995 to evaluate potential petroleum-related sources adjacent to the UST basin and the OWSs. Based on data collected during the February 1995 CAP investigation, additional soil borings were drilled to further evaluate the lateral and vertical extent of soil impacted by petroleum-related sources adjacent to the UST basin and to provide data to facilitate the removal of the USTs and the OWSs and remediation of impacted soil. The additional assessment activity, as proposed in the amended CAP, was approved by the BFD on June 30, 1995, and was completed during July 1995. The results of February and July 1995 investigations in the UST and OWS areas are discussed below. 3.1 CONDITIONS ASSESSMENT CAP fieldwork was conducted on site in February and July 1995 to determine the potential vertical and lateral extent of impacted soil. The July 1995 fieldwork was implemented to delineate the lateral and vertical extent of impacted soil identified in the UST and OWS areas during performance of the February CAP. 3.1.1 Sampling Locations A total of nine soil borings were drilled and sampled during the February and July 1995 subsurface activities. S0il boring locations are illustrated in Figure 2. Six of the borings were drilled around the UST basin while the remaining three borings were drilled in the OWS areas. Following is a description of the soil boring locations: January 5, 1996 (DRAFT) SECOR International Incorporated 3 · Soil boring A-1 was completed at a 25 degree angle, west of the UST basin, to a depth of 40 feet below ground surface (bgs). This boring was completed during the CAP fieldwork in February 1995. · Soil boring A-2 was completed at a 25 degree angle, south of the UST basin, to a depth of 75 feet bgs. This boring was completed during the CAP fieldwork in February 1995. · Soil boring A-3 was completed vertically, east of the UST basin, to a depth of 30 feet bgs.

This boring was completed during the additional CAP fieldwork in July 1995. · Soil boring B-1 was completed vertically, north of the Oil/Water Separator (OWS) Area, to a depth of 20 feet bgs. This boring was completed during the CAP fieldwork in February 1995. · Soil boring B-2 was completed vertically, south of the OWS Area, to a depth of 20 feet bgs. This boring was completed during the CAP fieldwork in February 1995. · Soil boring C-1 was completed vertically, adjacent to used-oil UST Area, to a depth of 20 feet bgs. This boring was completed during the CAP fieldwork in February 1995. Groundwater was not encountered at the deepest boring completion depth. 3.1.2 Analytical Methods During the initial (February 1995) and additional (July 1995) CAP activities, soil samples were submitted for analysis to Zymax Envirotechnology of San Luis Obispo, California. Zymax is a California state-certified laboratory. Selected soil samples collected during the initial CAP fieldwork were analyzed for total petroleum hydrocarbons as gasoline (TPH-G) by EPA Method 8015 modified, total pe[roleum hydrocarbons as diesel (TPH-D) by EPA Method 8015 modified, volatile organic compounds (VOCs) by EPA Method 8260, total lead by EPA Method 7420, and cadmium and chromium by EPA Method 6010/7000. Soil samples collected during the additional CAP activities were analyzed for TPH-G, TPH-D, and/or BTEX by EPA Method 8260, and for the leaking underground fuel tank (LUFT) 5 heavy metals (cadmium, chromium, lead, nickel and zinc) by EPA Method 6010. January 5, 1996 (DRAFT) SECOR International Incorporated 4 3.1.3 CAP Results 3.1.3.1 Subsurface Soil Conditions A fine-grained unit, ranging from a clay to a clayey and sandy silt was encountered in the borings from grade to 15 feet bgs. A fine-to medium-grained sand was encountered from 15 feet bgs to the total depth of all the 20-foot borings and the 40-foot boring. A silty clay was encountered in boring A-2 from 55 to 60 feet bgs. At 60 feet bgs, a fine-grained sand interbedded with sandy clay was encountered to the total depth of boring A2, 75 feet bgs. Groundwater was not encountered and is reportedly greater than 200 feet bgs. 3.1.3.2 Soil Sample Analytical Results Following is a summary of the subsurface soil sampling and analytical results for each of the investigated areas. Analytical results of the soil samples collected from each area are summarized in Table 1 and illustrated in Figure 3. The laboratory data reports are included in Appendix B. UST Basin Seven soil borings, A-1 through A-6 and C-1 were drilled around the former UST basin. The results of these borings are presented below. Boring A-1 Boring A-1 was located west of the UST basin. The boring was drilled at an angle of approximately 25 degrees off center, toward the east and beneath the UST basin. Organic vapors were detected in angle boring A-1 at 20 feet bgs and the boring was extended to 40 feet bgs. The boring was terminated at 40 feet bgs, since the angled boring was crossing into the area that was previously sampled by boring A-2. Soil samples collected at 20 and 40 feet bgs were analyzed for TPH-D and did not exhibit concentrations at or above the MRL. The soil collected from 40 feet bgs was also analyzed for TPH-G, which was detected at a concentration of 5,200 mg/Kg. · The soil samples collected at 20 and 40 feet bgs were analyzed for VOCs. Toluene, ethylbenzene, and xylenes were detected in both soil samples at levels ranging from 3.27 mg/Kg (A-1 20) to 24.17 mg/Kg (A-1 40). Total chromium was detected at a concentration of 3.6 mg/Kg, and total lead and total cadmium were not detected at or above the MRL in samples collected from boring A-1 at 20 feet bgs. Boring A-2 Boring A-2 was located south of the UST basin. Boring A-2 was drilled at an angle of approximately 25 degrees off center, toward the north, under the UST basin. Organic vapors were detected in boring A-2 at 25 feet bgs. Because the OVM readings were elevated, the boring was extended. Elevated OVM readings were recorded from 25 to 55 feet bgs. At 55 feet bgs, a silty clay was encountered and organic vapors declined. From 70 to 75 feet bgs, two consecutive soil samples had OVM readings of below 10 parts per million (ppm) and the boring was terminated. January 5, 1996 (DRAFT) SECOR International Incorporated 5 concentration of 6,600 mg/Kg. Soil samples collected at 30 and 45 feet bgs were analyzed for VOCs. Benzene, toluene, ethylbenzene, and total xylenes were detected in both samples. Soil samples collected at 60 feet bgs were analyzed for TPH-G, TPH-D, and VOCs; of the analytes, none were detected above the MRL. Soil samples collected at 75 feet bgs were analyzed for TPH-D and VOCs. None of the analytes were detected above the MRL. Total lead, chromium, and cadmium were analyzed in the 30 and 75 foot samples. Total lead was detected at a concentration of 29 mg/Kg in the soil sample collected at 30 feet bgs and none were detected above the MRL in the 75-foot sample. Total chromium concentrations ranged from 1.9 mg/Kg at 75 feet bgs to 3.9 mg/Kg at 30 feet bgs. Total cadmium concentrations were not detected at or above the MRL at 30 and 75 feet bgs. Boring A-3 Boring A-3 was drilled vertically, east of the UST basin. Organic vapors were detected in boring A-3 at 20 feet bgs. Because OVM readings were encountered at the base of the boring and at the request of CECo, this boring was extended to 30 feet bgs. Soil samples collected at 20 and 30 feet bgs in boring A-3 were analyzed for TPH-G, TPH-D, and VOCs; none were detected above the EPA method reporting limit (MRL). The soil sample collected at 20 feet bgs was analyzed for total lead and total cadmium and the results did not indicate any analyte concentrations above the MRL. Total chromium was detected at a concentration of 2.8 milligrams per kilogram (mg/Kg) in the soil sample collected at 20 feet bgs. Borin~ A-4 Boring A-4 was located south of the UST basin, and was extended to a depth of 70 feet bgs. Field screening measurements of organic vapors using a PID were observed in a range of 2.8 ppm at 5 feet bgs, to 26 ppm at 35 feet bgs. Soil samples collected at 35, 50, 60, and 70 feet bgs were analyzed for TPH-G and BTEX. The soil sample collected from 70 feet bgs was also analyzed for TPH-D. The results did not indicate analyte concentrations at or above the MRL. Soil sample A-4 35 was analyzed for LUFT heavy metals. Chromium, nickel and zinc were detected in concentrations of 4.4 mg/Kg, 1.7 mg/Kg and 18 rog/Kg, respectively. Cadmium and lead were not detected in sample A-4 35. Borin~ A-5 Boring A-5 was located northwest of the UST basin, and was extended to a depth of 60 feet bgs. Field screening measurements of organic vapors using a PID were observed in a range of 0 ppm at 60 feet bgs to 2.4 ppm at 20 feet bgs. The 40, 50 and 60-foot soil samples were analyzed for TPH-G and BTEX. The results did not indicate analyte concentrations at or above the MRL. Soil sample A-5 30, collected at 30 feet bgs, was analyzed for LUFT heavy metals. Chromium, nickel, and zinc were detected in concentrations of 3.7 mg/Kg, 1.8 mg/Kg, and 18 mg/Kg, respectively. Cadmium and lead were not detected in sample A-5 30. Boring A-6 Boring A-6 was located southwest of the UST basin. Field screening measurements of organic vapors using a PID were observed in a range of 0.5 ppm at 20 feet bgs to 7.2 ppm at 55 feet bgs. January 5, 1996 (DRAFT) SECOR International Incorporated 6 Soil samples collected at 25, 40, 50 and 60-feet bgs in boring A-6 were analyzed for TPH-G and BTEX. The soil sample collected from 60 feet bgs was also analyzed for TPH-D. The results did not indicate analyte concentrations at or above the MRL. Soil sample A-6 25, collected at 25 feet bgs, was analyzed for LUFT heavy metals] Chromium, nickel, and zinc were detected in concentrations of 6.2 mg/Kg, 3.3 mg/Kg and 41 mg/Kg, respectively. Cadmium and lead were not detected in sample A-6 25. Boring C-1 Boring, C-I, was drilled adjacent to the used oil UST to a depth of 20 feet bgs. OVM readings were not detected in the soil boring. The soil samples from boring C-1 were analyzed for TPH-D at 10 feet bgs and for TPH-D, VOCs, total lead, and total cadmium at 20 feet bgs. The results did not indicate analyte concentrations at or above the MRL. A total chromium concentration of 2.9 mg/Kg was detected in the 20-foot soil sample. 3.1.4 Oil/Water Separator Area Two borings, B-1 and B-2, were drilled north and south, respectively, of the OWS. Boring B-1 Boring B-I, was drilled adjacent to and north of the OWS to a depth of 20 feet bgs. OVM readings were not detected in the soil boring. Soil samples from boring B-1 were analyzed for TPH-D at 10 feet bgs and for TPH-D and VOCs at 20 feet bgs. The analytical results did not indicate the presence of either TPH-D or VOCs at or above the laboratory MRL. Boring B-2 Boring B-2, was drilled adjacent to and south of the OWS to a depth of 20 feet bgs. OVM readings were not detected in the soil boring. Organic vapors were encountered during drilling in boring B-2 at 10 feet bgs. The vapors were not observed at 15 and 20 feet bgs and boring B-2 was terminated. Soil samples from boring B-2 were analyzed for TPH-D at 10 feet bgs and for TPH-D and VOCs at 20 feet bgs. The soil sample collected at 10 feet bgs exhibited TPH-D at a concentration of 380 mg/Kg. VOC's were not detected at or above the laboratory MRL in either sample. 4.0 REMEDIAL CLOSURE ACTIVITIES Remedial closure activities were conducted at the site during September 1995. These activities are described below. 4.1 UST Basin 4.1.1 Excavation and UST Decommissioning On September 13, 1995, groundbreaking activities commenced within the UST basin. These activities included disconnection of the dispensers from the product distribution lines and removal of the concrete and/or asphalt pavement and surface soil overlying the USTs using a backhoe- operated impact hammer and bucket. Removal of the overlying material to a depth of 4 feet below ground surface (bgs) revealed that the orientation of UST Nos. 1 through 4 extended beneath the south wall of the building, as shown on Figure 2. In addition, approximately January 5, 1996 (DRAFT) SECOR International b~corporated 7 10 square feet of visibly impacted soil was observed adjacent to the mineral spirits UST No. 4, at an inaccessible location beneath the building. The used oil UST No. 5 was observed to be positioned within the basin but beyond the building foundation. Visually used-oil impacted soil was removed to a depth of 11 feet bgs in the area between the UST No. 5 and the adjacent steam-cleaning area and stockpiled on site for later disposal. An estimated 2 cubic yards of visually used-oil impacted soil was left in place beneath the steam-cleaning area pad to minimize the risk of compromising the structural integrity of the building foundation. The vertical limit of the used-oil impacted soil left in place was approximately 4 feet bgs based on visual observations conducted subsequent to excavation of the accessible impacted soil. Subsequent to exposing the USTs, residual product from each UST was sampled, characterized, and removed using a vacuum truck and each UST was inerted using a circulation-washing process which facilitated removal of all interior product and hydrocarbon vapors to concentrations below the lower explosive limits (LEL). Product volumes removed from the USTs included approximately 20 gallons of lube oil from UST No. 1, 152 gallons of diesel fuel from UST No. 2, 2 gallons of unidentified liquid from UST No. 4, and 288 gallons of used oil from UST No. 5. Impacted and non-impacted soil, concrete, and asphalt derived from the basin were temporarily stockpiled on site. Impacted soil was separately stockpiled on site for later disposal at Liquid Waste Management (LWM) in McKittrick, California. Unimpacted soil was stockpiled adjacent to the western boundary of the UST basin excavation and used as backfill material. Separation of impacted and non-impacted soil was conducted using visual and photoionization detector (PID) field screening techniques. On September 14, 1995, Mr. Ralph Huey of the BFD, conducted an inspection of the site. Based on the risk of potential building foundation damage that would result from removal of UST Nos. 1 through 4, Mr. Huey verbally approved the in-place decommissioning of the four USTs by backfilling with a cement-sand slurry and off-site decommissioning and disposal of the used-oil tank. As a result, a cement-sand slurry, mixed in a ratio of 2 sacks of Portland cement per cubic yard of sand, was pumped through a tremie pipe until slurry was displaced through the uppermost opening of USTs 1 through 4. Slurry was then manually placed into piping connected to floor access ports inside the building. The used-oil UST No. 5 was removed and transported off site for disposal at Gibson Oil Company in Bakersfield, California (Gibson). Prior to backfilling the excavation, Mr. Huey of the BFD also requested that confirmation soil sampling be performed beyond the position of the used-oil UST to determine the potential extent of impacted soil and within the areas of used-oil impacted soil removal to facilitate BFD consideration of final site closure. Used-oil impacted soil was removed based on visual observations as approved by the BFD. Subsequent to the confirmation soil sampling, the UST excavation was backfilled with approximately 10 cubic yards of unimpacted excavated soil. Confirmation soil sampling and characterization is discussed below. 4.1.2 Confirmation Soil Sampling/Analysis Confirmation soil sampling was performed prior to and subsequent to removal of the used-oil UST. The sample locations are illustrated in Figure 2. Soil samples were coll.ected using a truck-mounted hollow-stem auger drilling rig and split-spoon sampling techniques from depths of 10 and 20 feet bgs, respectively. Samples C1-10 and C1-20 were collected from approximately one foot from the southeastern edge of the waste-oil UST and samples DI-10 and D1-20 were collected from approximately 12 feet northeast of the UST (oil filter drain area). Soil borehole logs are included as Appendix A. January 5, 1996 (DRAFT) SECOR International Incorporated 8 Following removal of the waste-oil UST, soil samples WO1 and WO2 were collected from within the confines of the UST footprint at depths of 8.5 and 14.5 feet bgs, respectively. Samples WO3 and WO4 were respectively collected from the center of the used-oil impacted soil remaining in place at a depth of 3 feet bgs and from 2 feet south of WO3 at a depth of 6 feet bgs. In addition, to assess the depth of visually used-oil impacted soil left in place, sample WO5 was collected from a small area approximately 2 feet south of sample WO3 at a depth of approximately 13 feet bgs, where no further soil discoloration was observed. These samples were collected by inserting brass sleeves into excavated soil contained within the backhoe bucket. The brass sleeves were sealed with Teflon sheets, polyethylene end caps, and sealed with electrical tape. Each tube was subsequently labelled, stored on ice in an insulated cooler, and transported under chain-of-custody procedures to B.C. Labs in Bakersfield, California (B.C. Labs) for analysis. Used-oil UST removal and soil sampling activities were witnessed and approved by the BFD. Soil samples Ci-10, C1-20, DI-10, and D1-20 were analyzed for total petroleum hydrocarbons as diesel (TPH-D) by EPA Method 8015 Modified. Samples WO1, WO2, and WO5 were analyzed for TPH by EPA Method 418.1. In addition, samples C1-20 and D1-20 were analyzed for volatile organic compounds (VOCs) by EPA Method 8260. Samples C1-20, D1-20, WO1, WO2, and WO5 were also analyzed for cadmium, chromium, and lead by EPA Methods 6000/7000. Samples WO3 and WO4 were archived for possible analysis. 4.1.3 Confirmation Sample Analytical Results The organic analytical results did not indicate the presence of TPH-D or VOCs at or above the laboratory method reporting limits in the analyzed samples. TPH was detected at concentrations of 41 milligrams per kilogram (mg/Kg) and 50 mg/Kg in samples WO1 and WO2, respectively. The inorganic results indicated only the presence of chromium in each of the analyzed samples ranging from 2.9 mg/Kg (CI-20) to 18 mg/Kg (WO2). Sample analytical results are summarized in Table 1. The laboratory data reports are included in Appendix B. 4.2 Oil/Water Separators 4.2.1 Removal and Disposal Prior to OWS removal, liquid/sludge samples were collected from the western OWS chambers on September 6, 1995, for hazardous waste characterization and selection of disposal options. On September 20, 1995, the eastern and western OWSs were emptied and cleaned using a vacuum truck and a circulation washing process, as described in Section 3.1. Recovered product volumes included approximately 675 gallons (eastern OWS) and !,500 gallons (western OWS). Approximately 4,500 gallons of product and rinsate were removed and transported to Gibson for disposal. During OWS demolition and removal, the piping system configuration was documented and is illustrated on Figure 2. Observations indicated the western OWS was connected to the eastern OWS by a 4-inch cast iron pipe. In addition, a 4-inch cast iron pipe was connected to the southernmost end of the eastern OWS and apparently served as the OWS system discharge conduit to the city sewer system through a 4-inch cast iron pipe extending north beneath the steam-cleaning area. No additional OWS piping was observed which suggested the presence of an alternate discharge. Subsequent to liquid removal and concrete washing, the OWS's were demolished with a backhoe- mounted impact hammer and bucket. Concrete rubble and visually impacted soil were removed January 5, 1996 (DRAFT) SECOR International b~corporated 9 and separately stockpiled on site for later disposal at LWM. The maximum depths of excavation in the eastern and western OWS cavities were approximately 12 and 10.5 feet bgs, respectively. The limits of excavation within each cavity were based on a lack of visibly impacted soil at depth, as determined by the on-site SECOR field geologist and approved by the BFD. After collection of soil confirmation samples from the areas excavated beyond the impacted soil, each cavity was backfilled with clean imported soil, using a backhoe and compactor. 4.2.2 Confirmation Soil Sampling/Analysis Subsequent to removal of the western OWS concrete rubble from the excavation, confirmation soil samples OWSA and OWSB were collected from the excavation bottom at a depth of 10 feet bgs to verify the reliability of visual cleanup depths, as approved by the BFD. The sample locations are illustrated in Figure 2. Confirmation samples were not collected from the eastern OWS excavation as western OWS samples were considered representative. These samples were collected by inserting brass sleeves into excavated soil from the confirmation sample depth contained within the backhoe bucket. The brass sleeves were sealed with Teflon sheets, polyethylene end caps, and sealed with electrical tape. Each tube was subsequently labelled, stored on ice in an insulated cooler, and transported under chain-of-custody procedures to B.C. Labs for analysis. The confirmation samples were composited into one sample, OWSA/OWSB at the project laboratory. Confirmation soil sample OWSA/OWSB was analyzed for TPH by EPA Method 418.1 and for cadmium, chromium, and lead by EPA Methods 6000/7000. 4.2.3 Confirmation Soil Sample Analytical Results Analytical results for the OWSA/OWSB composite soil sample did not exhibit TPH and total cadmium at or above the laboratory MRL. Total lead and chromium were detected at concentrations of 4.1 mg/Kg and 22 mg/Kg. Based on a 10-fold dilution (the dilution of the STLC method) of the detected total metal values, the respective theoretical STLC extract concentrations were below the respective lead and chromium regulatory levels of 5 mg/L and 560 mg/L. Sample analytical results are summarized in Table 1. The laboratory data reports are included in Appendix B. 5.0 SITE RESTORATION On September 22 and 25, 1995, the site surface in the remediated areas were restored to grade with approximately 160 cubic yards of clean, imported soil, using a front-end loader and a vibrating compactor. From October 16-19, the backfilled areas of the site were resurfaced with a concrete layer approximately 6 inches thick. January 5, 1996 (DRAFT) SECOR International Incorporated 10 6.0 CONTAMINANT FATE AND TRANSPORT 6.1 Potential Contaminant Sources Based on visual observations and confirmation soil sample data collected during remedial activities at the site, native soil beneath the former used-oil UST does not contain TPH or benzene, toluene, ethylbenzene and xylenes (BTEX) concentrations exceeding LUFT manual guidelines. Based on the February 1995 CAP fieldwork and July 1995 additional investigation, an estimated volume of 190 cubic yards of impacted soil containing TPH-G at concentrations exceeding 1,000 mg/Kg remains in place at a maximum estimated depth of 55 feet bgs beneath decommissioned UST No. 3. The approximate configuration of the impacted soil volume is conical, with a base diameter of 22 feet and height of approximately 40 feet, and is illustrated in Figures 4 and 5. The impacted soil appears to be separated from groundwater by an estimated 175 feet of unimpacted soil. The non-impacted soil contains a low-permeability clayey deposit as shown on Figure 5, at approximately 52 to 57 feet bgs, which underlines and may extend laterally beyond the impacted soil. Approximately 10 percent (19 cubic yards) of the soil remaining in place and containing TPH-G in concentrations greater than 1,000 mg/Kg is estimated to contain BTEX in excess of LUFT manual guidelines of l, 50, 50, and 50 mg/Kg, respectively. This estimate is based on the following comparison between TPH-G and BTEX concentrations detected in the two soil samples with the greatest concentrations of TPH-G: · Soil sample A2-40, collected at 40 feet bgs in Boring A2, contained TPH-G at a concentration of 5,200 mg/Kg, and BTEX at concentrations of < 1.0, 54, 24, and 170 mg/Kg, respectively. The concentrations exceed LUFT manual guidelines for toluene and xylenes, and are below LUFT guidelines for benzene and ethylbenzene, · Soil sample A2-45, collected at 45 feet bgs in Boring A2, contained TPHg at a concentration of 6,600 rog/Kg, and BTEX at concentrations of 1.2, 100, 30, and 280 rog/Kg, respectively. The concentrations exceed LUFT manual guidelines for benzene, toluene and xylenes, and are below LUFT manual guidelines for ethylbenzene. Based on these data, SECOR performed a fate and transport analysis on TPH-G and BTEX utilizing the U.S. EPA Seasonal Soil Compartment Model (SESOIL). The model was selected to evaluate the likelihood of residual TPH-G and BTEX in on-site soil impacting groundwater in the vicinity of the site as a result of natural precipitation and infiltration processes. The potential for groundwater impact was assessed through consideration of three model pathways including a) simulation of the movement of chemicals within the unsaturated zone; b) determination of the impact of surface or subsurface contamination of soil, in terms of mass or concentration, to groundwater; and c) estimation of the time required by the contaminants to travel within the unsaturated zone to groundwater. The model results are discussed below. Model selection and description, development, methodologies, and assumptions are presented in Appendix C. The model results and conclusions are presented below. 6.2 Model Results and Conclusions The results of the SESOIL model scenarios are summarized in Table 2. The results from each scenario predict no future impact to groundwater for a period of 100 years from residual benzene concentrations present in the soil. The worst-case scenario 4, where the entire soil compartment was assumed to consist of sand layer intrinsic permeabilities, exhibited a maximum vertical migration depth for benzene of January 5, 1996 (DRAFT) SECOR laternational b~corporated 11 approximately 167 feet (5106 cm) bgs at a predicted maximum concentration of 0.307 ppm. Based on the input parameters, the results from scenarios 2 and 5 are likely the most representative of actual fate and transport. In scenarios 3 and 6, higher benzene concentrations, including 0.751 ppm and 1.7 ppm, exist at maximum depths of 97 feet bgs. The magnitude of these values may be artificially elevated based on the fact that the SESOIL model is extremely sensitive to large changes in permeability values between adjoining layers and the effects of interpermeability variations may not be accounted for by the model while estimating the chemical concentrations. As an example, scenarios 3 and 6 exhibit intrinsic permeabilities for Layer 3 at two orders of magnitude less than the permeabilities for Layers 2 and 4. This most likely accounts for the high benzene concentrations at depth. In addition, based on the fact that the site surface is sealed with a concrete and asphalt surface, recharge due to infiltration of rainfall would be considerably less than the values currently assumed. As such, benzene concentrations predicted by the model at its maximum vertical depth and time period are overly conservative. The concrete surface layer and underlying sandy silt were not included in the soil compartment due to the effects of its negligible permeability and resulting inaccurate model output. Instead, the model scenarios assume the initial 20 feet of unsaturated zone at the site consists of a sandy soil layer for purposes of conservative estimation and evaluation. Incorporating the obvious effect of a concrete surface seal at the site, benzene migration would be significantly reduced for the 99-year period. This phenomenon was noticeable when the permeability of the silty clay layer (Layer 3) was decreased to the existing literature values as shown in scenarios 2 and 6. Furthermore, no solute degradation was assumed for any of the model scenarios based on the randomness of the process. Nonetheless, residual benzene remaining in the soil would naturally degrade and attenuate with time, further limiting its migration and reducing its concentration. In conclusion, the SESOIL model conservatively predicts no future impact to groundwater from the residual benzene present in the soil for a period of 99 years. 7.0 CONCLUSIONS AND RECOMMENDATIONS Based on the results of previous site assessment activities, the findings presented in this report, and the State Water Resources Control Board LUFT Field Manual (1989), SECOR recommends that no further remedial action be required for TPH-G-impacted soil at the site. This recommendation is based on the limited depth (less than 45 feet bgs) of concentrations exceeding action levels for TPH-G-impacted soil remaining in place, the SESOIL model results, the depth to underlying groundwater (approximately 230 feet), and the presence 6f a concrete/asphalt surface seal which would significantly limit potential vertical migration of identified petroleum constituents in soil.

These criteria include the following: · Accounts for the partitioning of chemical load between three media-soil pore space (air), liquid (water), and solids (soil). · Simulates and evaluates the relationship between different physical and chemical processes occurring within the system that determine the movement of the chemicals within the vadose zone to groundwater. These processes typically include volatilization, evapotranspiration, infiltration, exfiltration, diffusion, leaching, absorption, desorption, recharge, and capillarity. · Exhibits the ability to simulate the on-site conditions and long-term chemical fate in the vadose zone. · Determines the vertical distance traveled by a chemical within the vadose zone at any given time. · Predicts the potential for impact of contaminants to groundwater. · Proven through extensive validation studies and readily acceptable by federal and state regulatory agencies. SESOIL is a one-dimensional seasonal compartmental model that simulates chemical transport for a period of 99 years within the vadose zone and is used to evaluate and assess the possible migration and magnitude of future impact of petroleum hydrocarbon constituents to groundwater. The SESOIL model estimates the rate of vertical chemical transport and transformation in a soil compartment in terms of mass and concentration distribution among the different phases (dissolved, adsorbed, vapor, and pure). The soil compartment is defined as a cell extending from ground surface through the unsaturated zone to the groundwater table. The major input components for the model include climactic data for the site area; soil compartment geometry in terms of layer thicknesses and area; physical soil data including porosity, intrinsic permeability, and organic carbon content; and the source chemical properties. Model output includes the mass and concentrations of the source chemical in the unsaturated zone and the mass contribution to groundwater. Model Development The model was developed based on site-specific criteria. These criteria included selection of the chemical of concern, development of a site stratigraphy model, selection of chemical load distribution for the soil compartment, and development of various fate and transport scenarios. These criteria are discussed below. Selection of the chemicals of concern is based on risk assessment, sample analytical results, and the physical properties of the chemicals detected at the site. This selection process includes an evaluation of physical properties such as Henry's Law Constant, water solubility, solubility in organic solvents, specific density, vapor density, maximum chemical concentrations, and the potential health impact based on the maximum contaminant levels for the underlying aquifer. Based on these factors, benzene was selected as the compound of concern for the worst-case fate and transport scenario. CUMBAK.SRP (DRAFT) SECOR International Incorporated C-I January 5, 1996 The site stratigraphy model was developed by utilizing soil borehole log data and sample analytical results from boreholes A1 and A2 to represent the physical characteristics and depths of the specific subsurface 'formations encountered. Based on the site stratigraphy, similarities in soil characteristics, and the distribution of benzene, the former tank pit area and underlying unsaturated zone was modeled as a conceptual soil compartment consisting of four layers having a total thickness of 230 feet. Layer 1, which consists of predominantly sandy silt with a silty sand layer, extended from ground surface to 42 feet bgs; Layer 2, a primarily sandy layer, extended from 42 feet bgs to the top of the silty clay layer at 52 feet bgs; Layer 3, a primarily silty clay layer, extended from 52 feet bgs to 62 feet bgs; and, Layer 4, a primarily fine sand layer, extended from 62 feet bgs to the top of the groundwater table at 230 feet bgs. Each of the four layers were further divided into sublayers to facilitate accurate resolution of the model. Layers 1 and 4 were divided into ten equal sublayers, while Layers 2 and 3 were respectively divided into two and five sublayers. Subsequent to selection of the chemical of concern and development of the site stratigraphic model, the chemical load distribution, in units of micrograms per square centimeter (/xg/cm2) was estimated for the soil compartment. Chemical load is calculated by multiplying the concentration of the contaminant of concern (benzene), in rog/Kg, the thickness of the layer in centimeters (cm), and the bulk density of the soil in gram per cubic centimeter (gm/cm3). Based on the sample analytical results from Borings A1 and A2, the maximum benzene concentration was determined to be 1.2 mg/Kg from A2-45 and the chemical load was assumed to be applied in the top sublayer of Layer 2 (from 42 feet bgs to 47 feet bgs). In addition, the chemical load was also applied for the entire area of the soil compartment. The thickness of the sublayer was 5 feet (152.4 cm) and the bulk density of the soil was assumed to be 1.5 gm/cm3, which lies within the range of values that are specified for sandy soils. Based on these values, a chemical load of 275 ttg/cm2 was applied in the top sublayer of Layer 2. Three scenarios were initially modeled for the site. In scenario 1, Layers 1 through 4 were given an intrinsic permeability value of 1 x 10.8 cm2. This value is was selected based on the recommendation in the SESOIL manual for sand layers. Other soil properties used for scenario 1 are summarized in Table 2. For scenario 2, Layers 1, 2, and 4 were assigned an intrinsic permeability of 1 x 10.8 cm2, while Layer 3 was assigned a conservative intrinsic permeability of 1 x 10-9 cm:. This value was higher than the value suggested in the SESOIL manual for silty clay soils (5 x 10-n cm2). The area of application was 100,000 cm2, which approximately represents the impacted southwestern area of the tank pit. Climatic data was based on the average seasonal climate data for the Bakersfield area. Detailed printouts of the model input parameters are included in Table AC-1. Sensitivity analysis was performed on the site model using different chemical load distributions. While the chemical load was still applied in Layer 2, the load was increased to account for a residual benzene concentration of 1.2 mg/Kg to be uniformly distributed over the entire 10-foot thickness of the layer. Hence, a chemical load of 660/xg/cm2 was applied in Layer 2. The additional parameters remained the same in the previous three scenarios. The "worst-case" scenario was best represented by Scenario 4, where the intrinsic permeabilities for the four layers were assumed to be equivalent to 1 x 10-8 cm:. As a result, this scenario was represented by a soil compartment entirely composed of a sandy soil colunm, with no silty clay layer occurring between 52 feet bgs to 62 feet bgs.

(SECOR), consultant for the Cummins Engine Company (CECO) and Cummins West, Inc. (CWI), on September 14, 1995: · Preliminary drilling activities conducted at the subject property prior to initiation of underground storage tank (UST) activities identified the presence of petroleum hydrocarbons as gasoline in soils in the UST basin area. · Excavation conducted at UST locations indicated in our Conditions Assessment Workplan dated May 24, 1995 (Workplan) revealed that the four USTs in the UST basin area, identified as a lube oil tank, a diesel fuel tank, a gasoline tank, and a mineral spirits tank; were located partially beneath a building. Due to the risk of structural damage to the building which would be created by UST removal, Mr. Huey approved the in-place decommissioning of the four USTs by removal of tank contents, internal pressure-washing of the USTs, removal of rinseate, and filling of the empty USTs with a 2-sack cement/sand slurry. · The waste oil UST identified in our Workplan was removed and disposed by Kern Environmental Service in accordance with regulatory requirements. Aassociated impacted soil which was accessible without risking structural damage to the building was also 5401 CaliJbrnia Avetlue, Suite 300, Bakersfield. C4 93309-0702 (805) 634-9541 (805) 634-9604 E-LY removed. Confirmation samples collected from in-place soil beneath the waste oil UST, and from the excavated soil stockpiled on site are being analyzed for the presence of petroleum hydrocarbon constituents. · Prior to approving closure of the USTs, it is our understanding that BFD will require a report documenting the UST decommissioning and removal activities and characterization of the gasoline impacted soil remaining in place. Additionally, the report should recommend site closure, remediation, or additional characterization, as appropriate. · SECOR will submit the report to BFD under separate cover, after completion of the UST decommissioning and removal activities and review and approval by CECO and CWI. We appreciate BFD's cooperation in expediting the investigation by providing timely field review and verbal approval of Workplan changes. If you have questions, or would like to discuss this letter in further detail, please call me or Mr. Mark Pishinsky at (805) 634-9541.

As discussed in our phone conversation, on June 13, 1995, we understand that this letter will meet your request for a response within 14 days. The following work has or is being performed by SECOR for Cummins Engine Company at the subject site. On March 3, 1995, SECOR notified the Kern County Department of Environmental Health of a release at the subject site. On June 12, SECOR submitted a work plan, dated May 24, 1995, to the Fire Department for approval. SECOR proposes to perform the work outlined in the plan to further assess the subject site prior to removal of the underground storage tanks (USTs). The subsurface characterization will enable SECOR and Cummins Engine Company to evaluate whether over-excavation of impacted soil is warranted prior to removing the USTs. SECOR is currently evaluating subcontractors and obtaining estimates to abandon and remove the USTs. We anticipate submitting the permit application for removal of the USTs to the Department after completion of the activities outlined in the work plan. 7730 &lie 3lobawk St., PO.

CUM-BKFD.CAW (DRAFT) SECOR International Incorporated May 24,1995 1.0 INTRODUCTION 1.1 Background SECOR International Incorporated (SECOR) has prepared this Conditions Assessment Workrplan (CAW) for Cummins Engine Company (CECO) and Cummins West Inc. (CWI) as part of the continued environmental assessment for the Bakersfield distributorship. The Bakersfield distributorship is located at 301 East 4th Street in Bakersfield, California (Figure 1). The Conditions Assessment (CA) field work, conducted on February 13 through 15, 1995, identified impacted soil in the area of the underground storage tank (UST) basin and the oil/water separator (OWS). The initial Conditions Assessment Plan (CAP) for the Bakersfield facility, dated January 26, 1995, allowed for the extension of three soil borings to evaluate the impacted soil. Although three borings were extended to 30, 40, and 75 feet below ground surface (bgs), the lateral and vertical extent of impacted soil was not delineated at that time. Based on the initial site assessment results, a CAW is required by the Kern County Environmental Health Services Department (KCEHSD) to delineate the lateral and vertical extent of impacted soil. The objective of this CAW is to evaluate the lateral and vertical extent of impacted soil, and evaluate the potential to impact groundwater conditions at the facility. The CAW has been prepared from information compiled as part of the initial CA phase of an environmental assessment for distributor transfer (EADT) at the Cummins West facility. This CAW has been prepared in accordance with the guidelines presented in KCEHSD's Handbook UT-35, Site Characterization and Remediation. 1.2 Regional Physiographic Conditions The subject property is at an elevation of approximately 405 feet above mean sea level (MSL). The topography in the vicinity of the subject site is generally flat, while the regional topography slopes to the south. The nearest surface water body is the East Side Canal, located approximately 0.75 mile north of the subject property. The average annual precipitation for the Bakersfield area, as measured at Meadows Field, is 5.74 inches. 1.3 Regional Geology The project site is located within the San Joaquin Valley, which constitutes the southern portion of the Great Valley geomorphic province. The Great Valley is a topographic and structural basin bounded on the east by the Sierra Nevada, a fault block dipping gently southwestward, and on the west by the Coast Range. The Sierra Nevada is composed of igneous and metamorphic rocks of pre-Tertiary age, which comprise the basement complex beneath the Valley. The Coast Range contains folded and faulted sedimentary rocks of Mesozoic and Cenozoic age, which are similar to the rocks that immediately underlie the Valley and noncomformably overlie the basement complex. In the Bakersfield area, the basement rocks are overlain by early to middle Tertiary age marine sedimentary rocks. The marine sediments are overlain by poorly consolidated, continental sediments that typically contain the regional groundwater reservoir. The continental sediments consist of alluvial fan and lacustrine deposits and reach an average depth of 2,000 feet bgs in the study area. May 24, 1995 (DRAFT) SECOR International Incorporated 1-1 1.4 Regional Hydrogeology The property is located in the San Joaquin Basin Hydrologic Study Area, which includes roughly two- thirds of the Great Valley. Within that area, a total of 39 groundwater basins and areas of potential storage have been identified. The inventory covers thirteen groundwater basins which have been identified as significant groundwater sources. The subject property is located within the Kern County groundwater basin. The Kern River flows in a southwesterly direction through Bakersfield and provides significant recharge to the area groundwater system. Water-bearing sediments beneath the site consist of late Tertiary and Quaternary age sand and gravel deposits of Sierran origin. Lacustrine deposits contemporaneous with the Corcoran Clay Formation are known to separate the upper and lower confined aquifers. Well data, as interpreted by Dale in the publication entitled "Ground Water Geology and Hydrology of the Kern River Alluvial Fan Area, California, 1966," suggests that a Corcoran Clay equivalent aquitard does not underlie the site. Data contained within the report entitled "1987 Report on Water Conditions," published by the Kern County Water Agency in February 1988, suggests the depth to water is approximately 200 feet bgs. The Kern County publication also suggests that the site is situated east of a regional groundwater depression. As a result, regional groundwater flow is interpreted as being towards the west in the vicinity of the subject property. 1.5 Historical Underground Storage Tank (UST) Usage Five USTs are located on the subject property and adjacent to the southwest building corner. The five USTs include a 1984 1,000-gallon mineral spirits UST, a pre-1984 1,000-gallon diesel fuel UST (connected to the dynamometer), a pre-1984 1,000-gallon lubricatingoil UST, a 1985 550-gallon gasoline UST, and a waste oil UST of unknown date and volume. No reports or other evidence which would indicate the presence of additional USTs were discovered during SECOR's September 21, 1994 inspection and associated Preliminary Site Assessment. The usage patterns and integrity status of the USTs were not determined. May 24, 1995 (DRAFT) SECOR International Incorporated 1-2 2.0 DESCRIPTION OF PREVIOUS FIELD INVESTIGATION 2.1 Health and Safety Plan A site-specific Health and Safety Plan (HASP) was generated for the facility site as part of the project. The HASP established personnel protection standards and mandatory safety practices and procedures for use during the field investigation. The HASP also included: · Information on suspected chemical compounds to be encountered. · List of monitoring equipment. · Required protective clothing and equipment. · . Map and directions to nearest hospital. · List of emergency telephone numbers. A copy of the site-specific HASP was presented to all SECOR field personnel and their subcontractors for review and signature. 2.2 Underground Utility Locations Prior to initiating the field investigation, a request was placed with Underground Service Alert notification center to conduct an underground utility survey in the vicinity of the site. In addition, SECOR subcontracted with Strata Geophysical, Inc. of Bakersfield, California (Strata) to perform a line location survey. Prior to the survey, SECOR marked the proposed locations of the soil borings. Strata then verified that the locations were clear of metal lines or piping. Prior to initiating field work, SECOR personnel verified the marking of nearby underground utilities and marked the final boring locations, based on the utility and line location survey. 2.3 Soil Boring Locations A total of five soil borings were drilled and sampled to evaluate potential petroleum-related sources adjacent to the UST basin and the OWS. Boring locations were selected based on data collected during the Preliminary Site Assessment (PSA) and are illustrated in Figure 2. 2.4 Installation of Soil Borings The soil borings were drilled from February 13 through 15, 1995. The borings were drilled by SBS Drilling, of Fresno, California (SBS), using a truck-mounted drill rig equipped with hollow-stem augers. SBS used 6-inch diameter augers that were decontaminated before and after drilling, and between each drilling location, with a hot water pressure wash. Wash water was captured and transferred into 55- gallon Department of Transportation (DOT) drums for later disposal by CWI. 2.5 Soil Sampling Soil samples in each boring were collected at 5-foot intervals using a California modified, split-spoon sampler fitted with 2-inch inside-diameter by 6-inch-long brass sampling tubes. The top sample was used for field screening and to characterize soil lithology. Field screening methods included visual observation of soil color changes and measurement of headspace vapor concentrations using a portable photo- ionization detector (PID). A RAE Systems, Inc. model PGM-35 PID was used for headspace vapor testing. Prior to use, this instrument was calibrated to a known isobutylene calibrant. May 24, 1995 (DRAFT) SECOR International Incorporated 2-1 Soil lithology was classified based on the Unified Soil Classification System and logged along with descriptions on a boring log. The bottom sample from each interval was retained for possible laboratory analysis. The soil sample with the highest PID reading or one from the base of each boring was submitted for analysis. In addition, based on field screening results, a second sample from each 20-foot boring and additional samples from the 30-, 40-, and 75-foot borings were also submitted for analyses. The borings were backfilled with an Enviroplug grout to grade. The top of the borings were capped with a concrete patch. 2.6 Analytical Methods Soil samples were collected in the field and were preserved as necessary. Based on soil boring location, sample depth, PID concentrations, and the CAP, soil samples were submitted for analysis to Zymax Envirotechnology (Zymax) of San Luis Obispo, California, a California state-certified laboratory. Selected soil sample analyses were chosen based on the material contents that may have been released from the point source(s) as outlined in the CAP. Selected soil samples collected from the borings were analyzed for total petroleum hydrocarbons as gasoline (TPH-G) by EPA Method 8015 modified, total petroleum hydrocarbons as diesel (TPH-D) by EPA Method 8015 modified, aromatic volatile organic (AVO) and halogenated volatile organic (HVO) compounds by EPA Method 8260, total lead by EPA Method 7420, and cadmium and chromium (Cd/Cr) by EPA Method 6010/7000. May 24, 1995 (DRAFT) SECOR International Incorporated 2-2 3.0 RESULTS OF PREVIOUS FIELD INVESTIGATION 3.1 Subsurface Soils Encountered A fine-grained unit, ranging from a clay to a clayey silt to a sandy silt, was encountered in the borings from grade to 15 feet. A fine- to medium-grained sand was encountered from 15 feet to the total depth of all the 20-foot borings and the 40-foot boring. The sand was underlain by silty clay encountered in boring A2 from 55 to 60 feet. At 60 feet, a fine-grained sand was encountered to the total depth of boring A2 (75 feet). Groundwater was not encountered, but the soil at the base of boring A2 was very moist. Depth to groundwater is estimated at approximately 80 to 100 feet bgs. 3.2 Field and Analytical Results Following is a summary of the subsurface soil sampling and analytical results for each of the investigated areas. Analytical results of the soil samples collected from each area are summarized in Table 1. 3.2.1 UST Basin Three soil borings, Al, A2, and A3, were drilled around the UST basin. Boring A1 Boring A1 was located west of the UST basin. The boring was drilled at an angle of approximately 25 degrees off center, toward the east and beneath the UST basin. Organic vapors were detected in angle boring A1 at 20 feet, and the boring was extended to 40 feet. The boring was terminated at 40 feet, since the angled boring was crossing into the area that was sampled by boring A2. Soil samples collected at 20 and 40 feet were analyzed for TPH-D and were nondetect. The soil collected from 40 feet was also analyzed for TPH-G, which was detected at a concentration of 5,200 milligrams per kilogram (mg/Kg). The soil samples collected at 20 and 40 feet were analyzed for HVOs. Toluene, ethylbenzene, and xylenes were detected in both soil samples. Total chromium was detected at a concentration of 3.6 mg/Kg. Total lead and total cadmium were not detected in samples collected from boring A1 at 20 feet. Boring A2 Boring A2 was located south of the UST basin. Boring A2 was drilled at an angle of approximately 25 degrees off center, toward the north, under the UST basin. Organic vapors were detected in boring A2 at 25 feet. Because the OVM readings were elevated, the boring was extended. Elevated OVM readings were recorded from 25 to 55 feet. At 55 feet, a silty clay was encountered and organic vapors declined. From 70 to 75 feet, two consecutive soil samples had OVM readings of below 10 parts per million (ppm), and the boring was terminated. The 30-foot soil sample was analyzed for TPH-D and was nondetect. The 45-foot soil sample was analyzed for TPH-G, which was detected at a concentration of 6,600 mg/Kg. Soil samples collected at 30 and 45 feet were analyzed for HVOs, and benzene, toluene, ethylbenzene, and total xylenes (BTEX) were detected in both samples. Soil samples collected at 60 feet were analyzed for TPH-G, TPH-D, HVOs May 24, 1995 (DRAFT) SECOR International Incorporated 3-1 (including BTEX), and AVOs, and were nondetect. Soil samples collected at 75 feet were analyzed for TPH-D, HVOs (including BTEX), and AVOs, and were nondetect. Total lead, total chromium, and total cadmium were analyzed in the 30- and 75-foot samples. Total lead was detected at a concentration of 29 mg/Kg in the soil sample collected at 30 feet and was not detected in the 75-foot sample. Total chromium concentrations ranged from 1.9 mg/Kg at 75 feet to 3.9 mg/Kg at 30 feet. Cadmium was not detected at 30 and 75 feet. Boring A3 Boring A3'was drilled vertically, east of the UST basin. Organic vapors were detected in boring A3 at 20 feet. Based on organic vapor readings at the base of the boring, and on the request of CECO and CWI, this boring was extended to 30 feet. Soil samples collected at 20 and 30 feet in boring A3 were analyzed for TPH-G, TPH-D, AVOs, and HVOs, and were nondetect. The soil sample collected at 20 feet was analyzed for total lead and total cadmium. No lead or cadmium was detected. Total chromium was detected at a concentration of 2.8 mg/Kg in the soil sample collected at 20 feet. Based on the field observations and analytical results, there appears to have been a gasoline release to the subsurface, beneath the UST basin. At the request of CECO and CWI, the KCEHSD was notified of the release on March 6, 1995. The California Leaking Underground Fuel Tank (LUFT) maximum allowable levels for gasoline in soil range from 10 ppm to 1,000 ppm, depending on site features. The TPH-G concentrations of 5,200 mg/Kg at 40 feet in boring A1 and 6,400 rog/Kg at 45 feet in boring A2 exceed the LUFT maximum allowable levels. In addition, total xylene and toluene concentrations in the soil samples collected at 40 feet in boring Al, and at 30 and 45 feet in boring A2, also exceed the LUFT maximum levels for those constituents. Total lead was detected at a concentration of 29 mg/Kg, from the soil sample collected at 30 feet in boring A2. No total lead was reported in any other sample. This concentration appeared to be above a background concentration of less than 10 mg/Kg. However, all detected lead concentrations were below the federal Total Threshold Level Concentration (TTLC) for lead in soil of 1,000 ppm. All other metal concentrations detected appear to be background concentrations. The lateral and vertical extent of impact to soil beneath the USTs has not been assessed. Organic vapors were detected in boring A2 from 25 to 55 feet. At 55 to 60 feet, a silty clay was encountered in boring A2. Beneath the silty clay, OVM readings declined significantly but were still present. Soil samples collected from beneath the clay at 60 and 75 feet contained no detectable TPH-G. Because boring A2 was drilled at an angle, these soil samples were collected approximately 10 to 20 feet north, laterally, relative to the 40-foot soil sample and the center of the UST basin. Based on the field observations and analytical results from soil samples collected from borings Al, A2, and A3, the lateral extent toward the south and west and the vertical extent of the hydrocarbon plume beneath the UST basin in soil have not been evaluated. SECOR recommends further evaluating the extent of impact to soil and groundwater from around the UST basin at the site. May 24, 1995 (DRAFT) SECOR International Incorporated 3-2 3.2.2 Oil/Water Separator Area Two borings, B1 and B2, were drilled north and south, respectively, of the OWS. Organic vapors were encountered during drilling in boring B2, located adjacent to the OWS, at 10 feet bgs. The organic vapors were not observed at 15 and 20 feet bgs, and boring B2 was terminated. Soil samples from boring BI were analyzed for TPH-D at 10 feet bgs and for TPH-G, HVOs, and AVOs at 20 feet bgs, and were nondetect in both samples. Soil samples collected at 10 feet bgs were analyzed for TPH-D, which was detected at a concentration of 380 mg/Kg. No TPH-D concentrations were detected in the sample at 20 feet bgs in boring B2. Based on the field observations and analytical results, there appears to have been a heavy-end hydrocarbon release to the subsurface, beneath the OWS. The TPH-D analytical result was nondetect at the base of boring B2. In addition, the TPH-D results were nondetect in borings A3, BI, C1, El, and Gl. As a result, the lateral and vertical extent of the impact to soil appears to be limited to the immediate vicinity of boring B2. Based on these results, SECOR does not recommend further evaluating the extent of impacted soil beneath the OWS until the time of OWS decommissioning. May 24, 1995 (DRAFT) SECOR International Incorporated 3-3 4.0 PROPOSED SCOPE OF WORK 4.1 Soil Borings SECOR proposes that three soil borings (A4, A5 and A6) be installed to further evaluate both the vertical and lateral extent of impact to the subsurface in the UST area, and the lateral extent of a low-permeability deposit encountered in boring A2. The three borings would be located northwest, southwest, and near the center of the UST basin, as shown on Figure 2. Prior to drilling at the site, the following tasks, notifications, and arrangements will be completed: · KCEHS will be notified of proposed field activities at least 72 hours prior to initiating any field work. · Drilling locations will be pre-marked, and underground Service Alert (USA) will be notified at least 48 hours prior to drilling to mark underground utilities near each drilling location. · The uppermost 5 feet of each boring will be excavated using a hand auger to check for buried utilities. The proposed borings would be drilled to a depth of 50 to 100 feet bgs. The soil borings will be sampled at 5-foot intervals using the split-spoon sampling procedure with a truck-mounted drill rig. Ali sampling equipment will be cleaned in an aqueous solution of trisodium phosphate or equivalent, rinsed with tap water, and rinsed a second time with deionized water to prevent cross-contamination between borings and sample intervals. Soil cuttings generated during drilling activities will be placed in DOT-approved 55- gallon steel drums and stored on site pending receipt of the analytical results. Soil cuttings will be properly disposed of by' CWI after receipt of analytical results. Soil samples will be evaluated using hydrocarbon vapors and appearance as criteria, and a headspace analysis will be quantitatively measured using a PID. Soil samples for potential chemical an. alysis will be immediately sealed with Teflon film and capped to avoid possible loss of volatile hydrocarbons. The sample sleeves will be labeled denoting the sample identification, date, and job description, and placed in a chilled cooler for delivery to a California state- certified analytical laboratory under chain-of-custody protocol. Remaining soil samples will be visually classified in accordance with the Unified Soil Classification System. All drilling will be completed by an experienced geologist working under the direct supervision of a California Registered Geologist. Boring A4 will be advanced to the low-permeability silty clay deposit, or to the depth of groundwater, whichever is encountered first. The lower extent of impacted soil will be tentatively identified when PID measurements indicate that two consecutive soil samples collected at 5-foot intervals have no detectable organic vapor concentrations. Selected soil samples may be analyzed on a rush turnaround basis to further evaluate the lower extent of impacted soil. If impacted soil is observed to persist beneath low- permeability deposits, or if no Iow permeability deposit is encountered, groundwater monitoring wells are proposed for installation in the borings in order to evaluate groundwater conditions. Completed soil borings not developed as wells will be abandoned in accordance with local regulatory guidance. Auger' flights will be progressively removed, and bentonite chips will be tremied through the augers and hydrated with potable water. Each boring will be sealed from total depth to finished surface grade. May 24, 1995 (DRAFT) SECOR International Incorporated 4-1 4.2 Groundwater Monitoring Wells Groundwater is estimated to be between 80 and 100 feet bgs at the subject site. Because the vertical extent of impact has been observed to be limited t6 soil overlying a silty clay encountered at 55 to 60 feet bgs in boring A2, no groundwater wells are proposed for installation at the site if chemical analytical and lithologic results for borings A4, A5, and A6 confirm that the low-permeability deposit is extensive and underlying impacted soil. If a groundwater investigation is required, the installation of up to five groundwater monitoring wells in two phases is proposed as discussed below. Prior to the installation of monitoring wells, permits for monitoring well installation will be obtained from KCEHSD. Groundwater is estimated to flow toward the west, based on topography and regional groundwater reports. At least three groundwater monitoring wells are required to evaluate the on-site groundwater gradient and flow direction. Monitoring wells will be installed in borings A4, A5 (cross-gradient to upgradient), and A6 (downgradient), as shown on Figure 2. If appropriate, based on data obtained from the three initial wells, two additional wells will be installed (see Section 4.3). Prior to installation, a soil boring will be drilled and sampled using procedures discussed in Section 4.1. 4.2.1 Casing Type, Diameter, Screened Interval, Filter Pack, and Slot Size Selection Twenty-foot sections of schedule 40 PVC 2-inch-diameter factory-slotted screen (0.020-inch slot size) will be capped by a PVC threaded bottom cap and placed at the base of each boring. Blank 2-inch diameter PVC casing will extend from the top of the screened interval to the ground surface. The top of the well casing will be covered with a locking, vented cap. The wells will screen the uppermost zone of saturation. The top of the well screens will be located at 10 feet above the estimated static water level. Lithologies encountered during drilling of previous borings indicate that a slot size of 0.020 inch will be appropriate for the construction of wells that yield samples with low levels of turbidity. Independent references indicate that a 0.020-inch slot size is recommended in formation material consisting predominantly of silts and sands (ASTM, 1988, and Gass, date unknown). A clean, standard graded (Monterey No. 3 or equivalent) sand filter pack will be placed in the annular space between the boring wall and the slotted screen section. The sand pack will extend from the base of the well screen to a height of approximately 1 to 2 feet above the top of the well screen, to allow proper sealing from the surface and adequate screen above the water table. 4.2.2 Depth and Type of Seal Approximately 1 foot of bentonite pellets will be placed above the filter pack, and hydrated with potable water. Cement grout containing three to five percent bentonite powder by weight will be placed above the bentonite pellet seal in each well. The wells will be constructed to allow placement of a minimum of 2.5 to 3 feet of surface seal, to allow for variation in well construction as described above. The wells will be completed at grade with locking steel covers and flush-mounted well housing enclosures. A schematic diagram of the proposed groundwater monitoring well construction design is presented on ~:~?~. 4.2.3 Monitoring Well Development Upon completion of monitoring well construction and after adequate time (a minimum of 24 hours) has been allowed for the cement well seals to set, the wells will be developed. Well May 24, 1995 (DRAFT) SECOR International Incorporated 4-2 development will involve pumping and mechanical surging (with a vented surge block) until groundwater is observed to be generally free of suspended sediments. A minimum of 5 wetted well casing volumes will be removed from each monitoring well during the development process. 4,2.4 Monitoring Well Sampling A minimum of 24 hours following well development, all of the wells will be checked for the presence of free, floating hydrocarbon product. If present, the thickness of the floating product will be measured to the nearest 0.0! foot. All water removed from the well will be inspected in the field for signs of sheen and/or odor. If floating product is present, the groundwater will not be sampled. However, any product will be bailed from the monitoring well. Initial measurements of depth to static water level and total casing depth will be made prior to groundwater sampling. The total well volume of water will be calculated for purge volumes. At the beginning of purging, and periodically thereafter, samples of purged groundwater will be collected in a clean container and the following field parameters/observations will be recorded: · Purge volume and time · Temperature · pH · Specific conductance · Depth to water · Turbidity · Color · Other observations as appropriate (drawdown in well during purge, presence of oil, odors, etc.) For wells providing sufficient yield, purging will be continued until field parameters stabilize and at least three casing volumes are removed. Wells providing insufficient yield will be purged dry once, allowed to recover to near original water levels, and purged dry again and then sampled when the water level has recovered. Wells with extremely low yields will be purged dry only once prior to sampling. Following purging, wells will be allowed to recover to near original water levels and will then be sampled. Samples will be collected using precleaned disposable bailers. During sampling, field parameters/observations will be recorded as previously described. Labels will be affixed to sample containers documenting the sample identification, date and time of collection, and collector(s). Chain-of-custody records will be completed and included with the samples, which will be transported at 4°C in insulated containers to the laboratory. Travel blanks prepared in the laboratory will be transported to the field and returned to the laboratory unopened. Specific conductance and pH meters will be calibrated daily. 4.2.5 Well Survey Following well construction, the ground surface elevation,, elevation of the well housing enclosure, and the elevation of the well casing (north side) will be surveyed to the nearest 0.01 foot. Well elevations will also be tied to a benchmark, which will be established for the site. Horizontal locations of the three new monitoring wells and the site benchmark will be surveyed to a local coordinate system established by the surveyor. May 24, 1995 (DRAFT) SECOR International Incorporated 4-3 4.3 Additional Investigation Two additional soil borings/monitoring wells are proposed as a contingency to further evaluate the lateral and/or vertical extent of impact to soil and/or groundwater, based on the results obtained from the first three soil borings and monitoring wells. The locations of the two additional borings/wells will be selected, based on soil and groundwater analytical results and the groundwater flow direction and gradient. Installation details would be in accordance with those described in Section 4.2. CECO, CWI, and KCEHSD will be contacted for approval prior to drilling the additional two soil borings/wells. 4.4 Analytical Program Selected soil samples will be collected in the field, preserved as necessary, and shipped to a California state-certified laboratory for analysis. A minimum of three soil samples from each boring will be submitted for analysis. The soil sample with the highest PID reading, or one from the base of each boring, will be submitted for analysis. In addition, two soil samples from between 30 and 60 feet bgs will also be submitted for analyses, based on field observations. Selected soil samples collected from the borings will be analyzed for BTEX by EPA Method 8020 and TPH-G by EPA Method 8015 modified. The soil sample with the highest TPH-G concentration, or one based on field observations, will also be analyzed for total lead, cadmium, and chromium (Pb/Cd/Cr) by EPA Method 6010/7000. The results of these tests will be used to characterize soil conditions and will assist in assessing the need and cost for remedial action. One groundwater sample from each monitoring well, if installed, will be analyzed for TPH-G by EPA Method 8015 modified, VOCs by EPA Method 8240, and Pb, Cd, and Cr by EPA Method 6010/7000. 4.5 Reporting Upon completion of field activities, a report will be prepared by SECOR that presents the results of the subsurface investigation outlined in this workplan. The report will be submitted to CECO and CWI for review and approval. The subsurface investigation report will be submitted to the KCEHSD within 60 days of completion of field activities.

One of the conditions provided on that page specified that "the owner and operator ensure that the facility have adequate financial responsibility coverage, as mandated for all underground storage tanks containing petroleum, and supply proof of such coverage when requested by the permitting agency." Federal regulations which went into effect in December 1988 required that all underground storage tank facilities obtain financial responsibility coverage, using an approved mechanism to pay for the costs of cleanup and any third party liability, in case of a leak from the tank system, and provide evidence of that coverage to the local imple- menting agency by deadlines established in law. The amount of coverage required and the mecha- nisms which could be utilized were also specified in law. In an attempt to assist underground storage tank facilities comply with thc financial responsibility requirements, the state developed a clean up fund, which was approved by the Federal EPA as a mechanism for meeting a portion of the Federal financial responsibility requirements. The state has prepared a summary of the clean up fund, how you pay into the fund, and the financial responsibility requirements. That summary has been enclosed with this letter. The Certificate of Financial Responsibility enclosed is the proof that this Department needs for the underground storage facility cited above. As shown by the example provided, you can utilize one statement for all underground storage tanks that you own or operate. Please review all information provided, complete the Certificate of Financial Responsibility enclosed, and return it by March 31, 1994.

All tanks shall be tested annually utilizing a tank integrity test which has been certified as being capable of detecting a leak of 0.1 gallon per hour with a probability of detection of 95 percent and a probability of false alarm of $ percent. The first test shall be completed before December 31, 1991, and subsequent tests completed each calendar year thereafter. All tank integrity tests completed after September 16, 1991, shall be completed under a valid, unexpired Permit to Test 'issued by the Environmental Health Services Department. 2. If present, all pressurized piping systems shall install pressurized piping leak detection 'systems and ensure that they are capable of functioning as specified by the manufacturer. The mechanical leak detection systems must be capable of alerting the owner/operator of a leak by restricting or shutting off the flow of hazardous substances through the piping, or by triggering an audible or visual alarm, detecting three gallons or more per hour, per square inch, line pressure within one hour. 3. If present, all pressurized piping systems shall be tested annually unless the facility has installed the following: a. A continuous monitoring system within secondary containment. b. The continuous monitor is connected to an audible and visual alarm system and the pumping system. c. The continuous monitor shuts down the pump and activates the alarm system when a release is detected. d. The pumping system shuts down automatically if the continuous monitor fails or is disconnected. The first test shall be completed before December 31, 1991, and subsequent tests completed each calendar year thereafter. 4. All underground storage tanks shall be retrofitted with overspill containers which have a minimum capacity of 5 gallons; be protected from galvanic corrosion, if made of metal; and be equipped with a drain valve to allow the drainage of liquid back into the tank by December 1998, or as specified by the Environmental Health Services Department. 5. All equipment installed for leak detection shall be operated and maintained in accordance with manufacturer's instructions, including routine maintenance and service checks (at least once per year) for operability or running condition. 6. An annual report shall be submitted to the Kern County Environmental Health Services Department each year after monitoring has been initiated. The owner/operator shall use the form provided within the Handbook UT-15. 7. ff present, all suction piping shall be monitored for the presence of air in the pipeline by observing the suction pumping system for the following indicators: a. The cost/quantity display wheels on the meter suction pump skip or jump during operation; b. The suction pump is operating, but no motor vehicle fuel is being pumped; c. The suction pump seems to overspeed when first turned on and then slows down as it begins to pump liquid; and d. A rattling sound in the suction pump and erratic flow, indicating an air and liquid mixture. 4 ~IEQUEST/ORDER FORMS i~h UT MONITORING MANUALS The Kern County Environmental Health Services Department will need to provide some underground storage facilities updated manuals which describe the methods which must be utilized to monitor underground storage tanks.
