SITE HISTORY REVIEW Site history was established by review of reports and documents previously prepared for the site by other consultants, review of documents at the KCEHD and review of aerial photographs. Review of Previous Reports ENSR reviewed reports prepared by other consultants, including Kennedy Jenks Consultants (KJC), Park Environmental and Soils Engineering Consultants, to obtain results of previous 8727-049 I I I i I I I I I I I I I I I i I I I Mr. Todd Bartok Costco Wholesale March 5, 2001 Page 6 environmental assessments of the site. A summary of the information from these previous reports is presented below. Site History The Sparks parcel, addressed as 2800 Standard Street, was most recently occupied by Minyard Trucking and Larry's Truck Service. Past uses of the Sparks parcel include oil fields that operated as early as 1937, with a large sump in the northwest corner of the parcel, the Trico oil production well in the eastern section, two ASTs in the northeast section, several smaller ASTs in the southern section and a large warehouse in the middle section. Between 1952 and 1956, the large sump was removed, the Trico oil production well was abandoned, the ASTs were removed, two Phillip's oil wells were installed and an oil field service building was constructed on this parcel. Between 1956 and 1975, the large warehouse in the middle section of the parcel was removed and, in 1979, a 2.1 million gallon crude oil AST (referred to as Tank 50001 in previous documents) and a smaller crude oil AST were constructed on the western portion of the parcel. In 1981, the truck service building currently present on the eastern portion of the Sparks parcel was constructed and piping was installed between the two crude oil ASTs and the abutting refinery to the north. Between 1981 and 1990, the piping connecting the crude oil ASTs to the adjacent refinery and the small crude oil AST were removed. The large AST was left in place. The Rosedale Hotel is listed as the current property owner of the Rosedale Hotel/Maaco parcel. This parcel, addressed as 3650/3660 Rosedale Highway, was occupied by residential buildings prior to construction of the current on-site building in 1982. This building was occupied by Maaco Auto Paint from the time of its construction until several years ago. The parcel was used for residential housing as early as 1937, with more residential buildings constructed on the parcel between 1956 and 1981. By 1982, the residential buildings were demolished and the building that was used by Maaco Auto Paint was constructed on the parcel. A Class V shallow disposal welt located on the east side of the Maaco Auto Paint building was destroyed according to KCEHD standards on October 8, 1993. The Seaton parcel, located between the Rosedale Hotel/Maaco and Glen Rose parcels along the Rosedale Highway, has been vacant or used for truck parking since as early as 1937. The Glen Rose parcel, addressed 3800/3880 Rosedale Highway, was used to store oil field equipment prior to i964. The current on-site building was constructed in 1964 and was 8727-049 I I I I I I I I I I I I I I I I I Mr. Todd Bartok Costco Wholesale March 5, 2001 Page 7 occupied betWeen 1964 and 2000 by Glen Rose Engine Shop. A Class V shallow disposal well located on the north side of the building was destroyed according to KCEHSD standards on September 16, 1994. Previous Site Assessments/Investigations A Phase I environmental site assessment (ESA) report was prepared by KJC and dated · October 22, 1997. KJC prepared recommendations based upon findings from the Phase I ESA that included the following: · Completion of an asbestos survey of all on-site buildings; · Clearing/disposal of debris; · Removal of the five USTs on the Sparks parcel; · Sampling of stained soils across the site; · Sampling/characterization of the crude oil AST contents; · Abandonment of water supply wells; · Removal of septic systems; and · Removal of drains and sumps. I~lumerous sampling activities have been performed at the site, including collection and analysis of samples of the crude oil AST contents; collection and analysis of soil and groundwater samples from across the site; and collection and analysis of sludge samples from the shallow disposal well, steam cleaner sump and floor drains. In addition, an asbestos survey of the on-site buildings was performed by AKRI Corporation (AKRI). The results of the previous site assessments are summarized below. For clarity, the results for the crude oil AST contents are discussed separately (and first) from the results of the soil, groundwater and sludge samples. Sampling of Crude Oil AST Contents Samples of the water, oil and sludge phases were collected in the past for analysis by CalNVestern Fuels, Park Environmental and KJC. These samples were analyzed for Title 22/CAM 17 metals, soluble lead and mercury, the aromatic hydrocarbons benzene, toluene, ethylbenzene and xylenes (BTEX); leachable benzene and leachable 1,2-dichloroethane (1,2- DCA); chromium and lead; organochlorinated pesticides and/or PCBs and reactive sulfide, reactive cyanide, pH', fish bioassay and flash point. 8727-049 I I I I I I I I I I I I I I Mr. Todd Bartok Costco Wholesale March 5, 2001 Page 8 Samples collected between 1989 and 1991 were analyzed for Title 22/CAM 17 metals using Total Threshold Limit Concentration (TTLC) and Soluble Threshold Limit Concentration (STLC) analytical methods, BTEX, 1,2-DCA and flash point. In addition, one sludge sample was analyzed for leachable lead using Toxicity Characteristic Leaching Potential (TCLP) analysis. Analytical results are summarized in the tables from previous reports presented Appendix A. These chemicals of concern (COCs) were not present in the samples analyzed at concentrations at or above their respective TTLCs, STLCs or TCLPs. In 1993, Park Environmental performed 'the first environmental assessment of the site which included collection and analysis of samples from the crude oil AST. Park Environmental collected two samples of the oil phase (designated T-1 and T-2) and two samples of the sludge phase (designated T-3 and T-4) from the crude oil AST. These four samples were analyzed for Total Recoverable Petroleum Hydrocarbons (TRPH), BTEX, leachable benzene using TCLP analysis and Title 22/CAM 17 metals. Petroleum hydrocarbons and BTEX were present in all of the samples. Leachable benzene was present in the sludge samples T-3 and T-4 at concentrations of 690 and 750 micrograms per kilogram (l~g/kg), respectively. These concentrations are above the TCLP of 500 micrograms per liter (IJg/L) for leachable benzene. The concentrations of metals were below their respective TTLCs. Additional samples of the tank contents were collected in 1997 by KJC and findings were reported in a waste classification information report dated March 1998. This work was performed in accordance with a California Department of Toxic Substances Control (DTSC) approved sampling workplan. These samples were analyzed for BTEX, 1,2-DCA, 2- methylnapthalene, fish bioassay, reactive sulfide, reactive cyanide, pH, flash point, Title 22/CAM 17 metals ('ITLC), soluble lead, mercury and barium using STLC analysis, PCBs, organochlorine pesticides, leachable benzene and 1,2-DCA using TCLP analysis, and leachable chromium and lead using TCLP analysis. DTSC reviewed the waste classification information report by KJC and requested additional analytical data for hexavalent chromium in the water phase, and lead and benzene in the sludge phase. In response to this request, KJC collected three water samples and eight sludge samples from the AST and reported the results in a waste classification information addendum dated March 21, 1998. Based on these analyses, the only COC above "action levels" was soluble lead detected in one sludge sample at a concentration above the STLC. Based on the analytical results and statistical analysis performed by KJC, the contents of the tank were characterized as non- 8727-049 Mr. Todd Bartok Costco Wholesale March 5, 2001 Page 9 hazardous. Results of the analysis are presented in the tables prepared by KJC and included in Appendix A. Additionally, KJC prepared a workplan for the removal and demolition of the crude oil AST (Tank 50001) dated March 12, 1998. The workplan was reviewed by the DTSC and the DTSC stated that they had no objections to the workplan in a letter dated .March 30, 1998. According to the workplan, an estimated 400,000 gallons of water would be removed from the AST, approximately 100,000 gallons of crude oil would be removed and recycled, approximately 420,000 gallons of sludge would be solidified and removed, the AST's interior would be decontaminated (with proper disposal of rinsate) and the AST would be cut into pieces and transported to a metal recycler. Based on the workplan by KJC and recent conversations between ENSR and DTSC representatives, the waste oil is to be disposed of at a DTSC permitted facility. Sampling of Sludge, Soil and Groundwater Extensive environmental subsurface investigations have been conducted at the site over the past 7 years by various consultants (see Sample Location Map, Figure 3). Investigative tasks at the site have included advancement of 47 deep soil borings and 18 shallow soil borings, collection and analysis of 110 subsurface soil samples and 12 "reconnaissance" groundwater samples, installation of three groundwater monitoring wells and collection and analysis of groundwater samples from the three mOnitori'ng wells and two water supply wells. Reconnaissance groundwater samples are collected by lowering a bailer through the probes or augers of the sampling rig; after sampling, the borings are backfilled with cement. During Park EnVironmental's 1993 environmental assessment of the Sparks parcel, soil samples were collected at depths of 15 to 35 feet below ground surface (bgs) from four borings (designated borings 1 through 4) located near the USTs. Analysis of these samples for fuel fingerprint (gasoline, diesel, motor oil and crude oil) revealed no detectable concentrations of petroleum hydrocarbons in these samples (see table from Park's report in Appendix A). The soil samples collected at depths of 20 and 30 feet bgs from the boring (Boring 5) advanced by Park Environmental at the wash rack leach field were analyzed for fuel fingerprint. Analyses of these samples revealed Total Petroleum Hydrocarbons quantified as crude oil (TPH-CO) at a concentration of 53 mg/kg and Total Petroleum Hydrocarbons as diesel (TPH-d) at 14 mg/kg. Samples collected at a depth of 1 foot bgs from around the crude oil AST (sample locations S-1 through S-5) were analyzed for TRPH, BTEX and Title 22/CAM 17 metals. TRPH was detected at concentrations above 1,000 mg/kg in four of the five samples. Various metals were detected in each of the samples at concentration below their respective TTLCs. In addition, BTEX 8727-049 I I 1 i I I I I I I i I I I I I Mr. Todd Bartok Costco Wholesale March 5, 2001 Page 10 compounds were detected in concentrations below action levels in four of the five samples; the remaining sample did not contain BTEX compounds at concentrations at or above the laboratory reporting limits. Soils Engineering, Inc. (SEI) advanced 31 borings across the site in 1998. Three of the borings (B28, B29 and B-30) located on the Sparks parcel were converted to groundwater monitoring wells (MW-l, MW-2 and MW-3). A total of 64 soil samples and three groundwater samples were collected by SEI for analysis. Soil samples were analyzed for TRPH, TPH-g, TPH-d, BTEX, methyl tertiary butyl ether (MtBE), Volatile Organic Compounds (VOCs), semi-VOCs, metals, organochlorine pesticides and/or PCBs. Petroleum hydrocarbons were detected in two of the shallow soil samples (collected at the 1 foot depth) at concentrations above 1,000 mg/kg. These samples were collected from borings located on the Seaton parcel and designated B-15 and B-16. Analysis of the groundwater samples for TPH-g, TPH-d, TRPH, VOCs and/or metals revealed Iow levels of some petroleum hydrocarbon constituents. The concentrations of these compounds were below generally accepted "action levels" (MCLs and taste/odor threshold). 'Samples of liquid and sludge were also collected for analysis by SEI from the Class V shallow disposal well on the Sparks parcel, the septic tanks on the Sparks, Rosedale Hotel/Maaco and Glen Rose parcels, the steam cleaner sump on the Glen Rose parcel and two floor drains on the Rosedale Hotel/Maaco parcel. The liquid and sludge in the shallow disposal well were characterized as non-hazardous while the sludge in the steam cleaner sump and two floors were characterized as hazardous based on the soluble metals analyses. ENSR performed a subsurface investigation at the site during the summer of 2000 and early 2001. A total of 14 borings were advanced to groundwater for collection of soil and groundwater samples and 12 shallow borings were advanced for collection of soil samples. Twelve groundwater samples and 27 soil samples were analyzed for TPH-g, TPH-d, TPH-mo, Title 22/CAM 17 metals and/or VOCs. Petroleum hydrocarbons above 1,000 mg/kg were detected in soil samples collected from two locations on the Sparks parcel, including EB-1 located north of the service garage and ES-10 located north of the crude oil AST.

Photograph dated July 1, 1946 In this photograph, the eastern portion of the Sparks parcel is disturbed with what appears to be small containers. Also noted in this photograph were a small structure that appears to be an AST at northeast corner of the Sparks parcel and a small structure, likely the warehouse noted by KJC, on the south central area of the Sparks parcel. The remainder of the Sparks parcel is undeveloped land in this photograph and appeared to have been mown (possibly for weed control). In this photograph, what appeared to be residential structures were present on the northern and central portions of the Rosedale Hotel/Maaco parcel. A number of trees were located on the central portion of this parcel at this time. This parcel was undeveloped land in this photograph. The Glen Rose parcel appeared as undeveloped land. Photograph dated October 21, 1952 The AST was not present on the northeast corner of the Sparks parcel in this photograph; however, the east portion of this parcel was still disturbed and occupied by what appeared to be containers located near the southeast corner. A square shaped feature was noted along the northern border to the east of Standard Street in this photograph. This feature may have been the sump noted, by KJC which was associated with the Trico oil well. Several trees were noted in the central area of the parcel and what appeared to be a drill rig was present on western portion (in area of Phillips Well No. 1) of the Sparks parcel.

SUBSURFACE INVESTIGATION A subsurface investigation was performed by ENSR at the site between June and December 2000 and in February 2001. This investigation included collection and analysis of soil and groundwater samples from borings located across the site. The site investigation is summarized below. Field Activities Prior to advancement of borings at the site, Strata Geophysical, a company specializing in geophysical services, surveyed the proposed sampling areas for underground utilities using various geophysical instruments. Underground Service Alert was also notified to arrange for utility marking within pertinent public rights-of-way and utility easements prior to commencement of field sampling activities. Due to access constraints and other delays, fieldwork was completed in phases between June 26, 2000 and February 6, 2001, as noted in the table below. Boring ID Number Drilling Date ES-l, ES-2, EB-1 and EB-2 June 26, 2000 ES-3, EB-3 through EB-5, EB-10 and EB-11 June 27, 2000 ES-7 through ES-10 and EB-7 through EB-9 July 11,2000 ES-11 through ES-13 and EB-12 July 21, 2000 ES-4 through ES-6 and EB-6 December 7, 2000 EB-13 and EB-14 February 6, 2001 8727-049 I I 1 I i' I I I ! ! Mr. Todd Bartok Costco Wholesale March 5, 2001 Page 15 No KCEHD permits were requi~d for the proposed sampling; however, KCEHD was notified of our schedule for fieldwork. ~' The borings were advanced by Vironex of Long Beach, California under ENSR's supervision with the exception of the sampling event in February 2001. In February 2001, borings EB-13 and EB-14 were advanced using a hollow stem drill rig which was under the supervision of Kleinfelder, Inc., the geotechnical engineer for the project. ENSR's role at that time was to collect soil and groundwater samples from the borings advanced by Kleinfelder. The remaining borings were advanced by ENSR using a direct-push Geoprobe TM sampling rig. The boring locations are shown on the Sample Location Map, Figure 3. The shallow borings were advanced to depths of approximately 4 feet bgs and the deep borings were advanced to depths of approximately 25 to 35 feet. The sampling equipment was washed in AlconoxTM detergent and water, and rinsed with distilled water or steam cleaned prior to use at each sampling location and prior to leaving the site. After the soil and groundwater samples were collected, the borings were backfilled with cement grout. S°il samples were generally collected from the deeper borings at intervals of five feet bgs to the soil/groundwater interface and from the surface to the 4-foot depth in the shallow borings. Groundwater samples were collected from each of the deeper borings. Sampling depths varied based on soil conditions and groundwater encountered in the borings consisted of sand, silt and silty sand. encountered during drilling at depths .of 24 to 35 feet bgs. depths. Materials Groundwater was The soil samples were collected in acetate tubes cut in 6-inch lengths. The tubes were' capped with TeflonTM tape and plastic end caps, labeled, and placed into an ice-cooled chest. Groundwater samples were collected using new disposable bailers lowered through the probe. Since this sampling was preliminary in nature, no purging or groundwater quality monitoring was conducted prior to sample collection. Each groundwater sample was decanted into laboratory supplied containers, appropriately labeled and placed into an ice- cooled chest. No.evidence of staining or discoloration was noted in the soils during our drilling activities. Soil vapor monitoring with a photoionization detector (PID) for total volatile organic compounds in soil samples collected from the borings detected only natural background concentrations. 8727-049 I I I I I I I I I I i i I i ,I I I Mr. Todd Bartok Costco Wholesale March 5, 2001 Page 16 Following collection of the soil samples, each boring was backfilled with neat cement. The soil cuttings from the borings and decontamination rinsate fluids were placed into labeled, 5-gallon containers and left on site fbr future disposal. Chemical Analyses and Results The soil and groundwater samples collected from the site were submitted to SunStar Laboratories, Inc. of Tustin, California. Zalco Laboratories, Inc. of Bakersfield, California and McCampbell Analytical, Inc. of Pacheco, California. These laboratories are certified by the State of California to perform the requested analyses. The analyses performed on selected soil and groundwater samples and the results are presented in Table 1 and Table 2; analytical methods utilized are summarized below. · Total petroleum hydrocarbons quantified as gasoline (TPH-g), TPH as diesel (TPH-d) and TPH as motor oil (TPH-mo) using modified EPA Test Method 8015, · Volatile organic compounds, including benzene, toluene, ethylbenzene and total xylenes (BTE×), using EPA Test Method 8010, 8021B or 8260; and · Title 22 Metals using the EPA Test Method 6010/7000 Series. The analyses performed for each sample are summarized in Tables 1 and 2. Copies of the chain-of-custody forms certified analytical laboratory reports are presented in Appendix' B. Soil Samples: Soil analytical results are summarized in Tables 3 and 4; analytical results for petroleum hydrocarbons are also shown on Plate 3. Please note that Table 4 presents only those samples in which petroleum hydrocarbons were detected at concentrations at or above the laboratory reporting limits. As shown in Table 3, various metals were detected in a number of the soil samples. The concentrations of metals detected were below their respective Total Threshold Limit Concentration (TTLC), residential Preliminary Remediation Goal (PRG) established by the EPA Region IX, and ten times the Soluble Threshold Limit Concentration (STLC) with the exception of arsenic, barium, lead and thallium. Generally, samples with total metals concentrations ten times the STLC are 'analyzed for soluble metals to establish if the soils would be considered hazardous waste if excavated during site development. 8727-049 !

The arsenic concentrations are above the cancer endpoint residential PRG of 0.39 mg/kg but below the non-cancer endpoint residential PRG of 22 mg/kg. Natural background concentrations of arsenic in the western United States range from less than 0.10 rog/kg to 97 rog/kg with an estimated arithmetic mean if 7.0 mg/kg. In ENSR's opinion, the concentrations of arsenic detected in the on-site soils appear to be consistent with natural background conditions and do not appear to represent a significant environmental concern. Total barium was detected in one soil sample,.ES-4-2, at a concentration of 2,100 mg/kg, which is below the TTLC of 10,000 mg/kg and the residential PRG of 5,400 mg/kg for barium but more than ten times the STLC of 100 mg/L. This sample was analyzed for soluble barium using soluble (STLC) analysis due to' the total barium concentration. Soluble barium was detected at a concentration of 2.4 mg/L, which is less than the STLC for barium, which suggests that barium concentrations in the area of sample ES-4 do not appear to present an environmental concern, and would not require disposal as hazardous waste. Total lead was detected in one soil sample, EB-6-0.5, at a concentration of 96 mg/kg, which is below the TTLC of 350 mg/kg and the residential PRG of 400 mg/kg for lead but more than ten times the STLC of 5 mg/L. This sample was analyzed for soluble lead using soluble analysis. Soluble lead was detected at a concentration of 0.41 rog/L, which is below the STLC for lead. Based on the Iow soluble concentration of lead, the soil in the area of sample EB-6 does not appear to present an environmental concern and would not require disposal as hazardous waste, in ENSR's opinion. Thallium was detected in two soil samples, EB-3-1 and EB-4-1, at concentrations of 9 and 8 mg/kg, respectively. These concentrations are slightly above the residential PRG of 6.3 rog/kg but are below the TTLC of 700 mg/kg, ten times the STLC of 5 mg/L and the PRG for industrial soils of 160 mg/kg. In ENSR's opinion, the concentrations of thallium detected in the on-site soils do not appear to present an environmental concern as they are below the PRG for industrial soils. No concentrations of TPH-g, BTEX or VOCs were detected above the laboratory reporting limits in the soil samples. Laboratory analyses of the soil samples revealed TPH-d and/or TPH-mo in the five of the soil samples (see Table 4). TPH-d and TPHomo were detected at concentrations of up. to 2,600 mg/kg and 1,000 mg/kg, respectively. According to the Leaking Underground Fuel Tank (LUFT) Field Manual, vadose zone soils would require remediation if 8727-049 I I I I ! i ! I i ,i I I I '1 ! Mr. Todd Bartok Costco Wholesale March 5, 2001 Page 18 TPH-d or TPH-mo are detected at concentrations ranging from 100 to 10,000 mg/kg (Leaking Underground Fuel Tank Task Force, 1989). TPH-d and TPH-mo were present in two of the soil samples, EB-I-1 and ES-10-4, at concentrations that would most likely require remediation. Remediation goals for TPH-d and TPH-mo are evaluated on a case-by-case basis using criteria such as depth to water, beneficial uses, land use, and proximity of sensitive receptors. Groundwater Samples: Groundwater analytical results are summarized in Tables 5 and 6. Please note that Table 6 presents only the sample in which petroleum hydrocarbons were detected at concentrations at or above the laboratory reporting limits. As shown on Table 5, the concentrations of metals were below their Maximum Contaminant Level (MCL) for drinking water in California. VOCs were not present in the groundwater samples collected from the site. Petroleum hydrocarbons were not detected in the groundwater samples with the exception of samples from boring EB-14. TPH-d and TPH-mo were detected in the groundwater samples from this boring at concentrations of 120 and 280 micrograms per liter (p.g/L), respectively. CONCLUSIONS AND RECOMMENDATIONS Our site history review indicated that a number of issues will need to be addressed at the site. ENSR has prepared a draft Removal Action Workplan (RAW) for the site which presents the scope of work for removal of the crude oil AST, the USTs, impacted soils, sumps, septic systems and the Class V shallow injection well and destruction of water wells and former oil wells. Two areas (EB-1 and ES-10) which would likely require remediation were identified based on the analytical results of this inveStigation. Removal of soil from these two areas is discussed in our RAW. Petroleum hydrocarbons were detected in the groundwater sample collected from boring EB- 14, advanced near the southeast corner of the site. TPH-d and TPH-mo were detected in this groundwater samples from this boring at concentrations of 120 and 280 I~g/L, respectively. The 8727-049 I I I i I I I ! I I I ! I I i I I I Mr. Todd Bartok Costco Wholesale March 5, 2001 Page 19 source of petroleum hydrocarbon impacts is unknown at this time. According to information obtained during our Phase I ESA, no USTs are currently or were previously located in this area of the site. The septic tank/leachfield and former hazardous materials storage areas at the former Maaco facility are located in an up-gradient direction; however, analysis of soil samples collected in the past by previous consultants from these areas did not reveal petroleum hydrocarbons at concentrations at or above the laboratory reporting limits. ENSR recommends that Costco notify the City of Bakersfield Fire Department of the findings of this investigation. It is our understanding that Costco's plans include construction of a gasoline station on the site. ENSR recommends that the USTs associated with this station be constructed in compliance with applicable codes and laws so that Costco is not identified by the RWQCB as a contributing party to the presence of petroleum hydrocarbons in the groundwater beneath the site and vicinity. Documentation that no leakage from USTs at the gasoline station has occurred should be maintained by Costco for future reference. Sincerely, ENSR Corporation Lita D. Freeman, R.E.A.
