Mr. Anthony Olivieri of Olivieri Commercial Group, on behalf of Big O Tire Stores, provided written approval of Krazan & Associates, Inc. (Krazan) Proposal No. P98-277 dated July 30, 1998 to proceed with the Limited Phase II ESA. 2.0 BACKGROUND Krazan conducted a Phase I ESA for the subject site (report dated July 16, 1998), under the authorization of Big O Tire Stores. According to information reported in the Phase I ESA report, the subject site was developed in 1968 as a gasoline service station. Two 10,000-gallon gasoline underground storage tanks (USTs) were installed on the subject site in 1975. According to records on file with the City of Bakersfield Fire Department, Environmental Services. Department (CBESD), one 550-gallon waste oil UST (installed in 1968) and the two 10,000-gallon gasoline UST's (installed in 1975) were removed from the subject site in 1994. The former service station facilities and UST locations are shown on Figure 1. GeoResearch was contracted by Unocal Corporation (Unocal) to conduct the UST removal, additional investigations, and limited soil remediation at the subject site. 215 West Dakota Avenue · Clovis California 93612 · (209) 348-2200 · FAX (209) 348-2201 Offices Serving the Western United States 2498055.EA3 ! i I I i ! I I I I I ! I ! I ! I I I Project No. 024-98056 Page No. 2 Based on the results of the additional investigations and limited remediation conducted by GeoResearch at the subject site, the CBESD granted closure for the subject site in a letter dated October 5, 1994. However, no information regarding the fate of the late 1960s gasoline USTs (assumed to have been located on-site)} was presented by GeoResearch. The conclusions and recommendations of the Krazan Phase I ESA included the following: 3.0 Due to the lack of records for the installation and removal of gasoline USTs prior to 1975, it is necessary to confirm whether or not any prior UST generations exist beneath the subject site. A geophysical survey consisting of a magnetometer and a ground-penetrating radar reconnaissance survey of the subject site should be conducted to confirm that no other USTs exist beneath the subject site. Based on records reviewed at the CBESD, no sign~icant contamination exists beneath the subject site. Full closure for the demolition of the Unocal service station was issued by the CBESD on October 5, 1994. PURPOSE OF THE AUGUST 1998 LIMITED PHASE I1 ESA The purpose of the August 1998 assessment was to determine if the 1960s gasoline USTs remained on the subject site and if releases of petroleum hydrocarbon constituents (PHCs) are present in soils in the vicinity of the 1960s USTs. 4.0 SITE LOCATION AND DESCRIPTION The subject site is located on the northwest corner of Ming Avenue and Hughes Lane in Bakersfield, Kern County, California. According to the U.S. Geological Survey, 7.5 minute Gosford, California topographic map, the subject property is located in the southwest quarter of Section 1, in Township 30 South, Range 27 East, Mount Diablo Baseline and Meridian. The subject site is currently undeveloped vacant land. KRAZAN & ASSOCIATES, INC. Offices Serving the Western United States 2498058.EA3 I I 5.0 SCOPE OF WORK Project No. 024-98056 Page No. 3 I I I ! I I I I I The scope of Krazan's August 1998 Limited Phase II ESA included the following: On July 24, 1998, Krazan contracted with Maverick Environmental Services (Maverick) of Simi Valley, California to conduct a geophysical survey at the subject site. During the geophysical survey, Maverick identified the former (1994) UST excavation and an anomalous excavation (geophysical anomaly) at the subject site. The locations of the excavations identified by Maverick are shown on Figure 2. Based on the size and location of the anomalous excavation, it is anticipated that it may be a former location of the late 1960s USTs previously associated with the subject site. No existing USTs were identified by the July 24, 1998 geophysical survey at the subject site. Krazan prepared a Limited Phase II Environmental Site Assessment Workplan, 2502 Ming Avenue, Bakersfield, California, dated August 12, 1998, which was submitted to the CBESD for review and approval. In a letter dated August 13, 1998, Mr. Ralph Huey of the CBESD acknowledged the receipt of the work plan and indicated that Krazan may conduct the proposed work. Copies of the August 12, 1998 work plan and the August 13, 1998 CBESD letter are included in Appendix A. On August 18, 1998, two 20-foot soil borings (B-1 and B-2) were advanced within the limits of the geophysical anomaly. The locations of the soil borings are shown on Figure 2. Soil samples collected at 10 feet and 20 feet below ground surface (bgs) from these borings were submitted for chemical analysis. I I I The selected soil samples were analyzed for benzene, toluene, ethylbenzene, and xylenes (BTEX); methyl tertiary butyl ether (MTBE) by EPA Method 8020; and for total petroleum hydrocarbons as gasoline (TPH-G) by EPA Method 8015M. · Because no hydrocarbon odors, discolored soil or positive PID readings were noted during field operations, the soil borings were backfitled with drill cuttings. · Specific field methods employed are presented in Appendix B. I I I I 6.0 FINDINGS OF THE AUGUST 1998 LIMITED PHASE II ESA 6.1 Soil Profile and Field Observations Based on soil boring samples obtained at five foot intervals, the soil profile in the vicinity of the geophysical anomaly may be generalized as follows.

KRAZAN & ASSOCIATES, INC. Offices Serving the Western United States 2498058.EA3 7.0 DISCUSSION OF FINDINGS Project No. 024-98056 Page No. 5 During the July 24, 1998 geophysical survey conducted at the subject site, a geophysical anomaly was identified in the northwestern portion of the subject site. Based on the size and location of the geophysical anomaly, it is anticipated that it may be a former location of the late 1960s USTs previously associated with the subject site. No existing USTs were identified by the July 24, 1998 geophysical survey at the subject site. Based on the soil sample analytical results of the August 1998 Limited Phase II ESA, no detectable concentrations of BTEX, MTBE, or TPH-G were present in the samples. Additionally, no soil discoloration, hydrocar, bon odors, or positive PID readings were noted in any of the soil samples collected. · 8.0 CONCLUSIONS AND RECOMMENDATIONS Based on the findings of the Limited Phase II ESA, there are no indications that PHCs have impacted soils in the vicinity of the geophysical anomaly which is located within the northwestern portion of the subject site. It is Krazan's opinion that further assessment of the issuer related to the 1960s UST is not warranted. Krazan recommends that a copy of this report be submitted to the following: Mr. Howard Wines City of Bakersfield Environmental Services Department 1715 Chester Avenue, 3rd Floor Bakersfield, California 93301 9.0 LIMITATIONS The findings of this report were based upon the results of field and laboratory investigations, coupled with the interpretation of subsurface conditions associated with our soil borings. Therefore, the data are accurate only to the degree implied by review of the data obtained and by professional interpretation. The exploratory soil borings locations were located in the field by review of available maps and by tape measurement from, existing landmarks. Therefore, the soil borings locations should be considered KRAZAN & ASSOCIATES, INC. Offices Serving the Western United States 2498058,EA3 I I I I I I I I I I I I I I I I I I I Project No. 024-98056 Page No. 6 accurate only to the degree implied by the methods used to locate them. The conclusions presented in this report are based upon site conditions as they existed at the time of our field investigation. Additionally, it is assumed that the soil borings advanced on the subject site are representative of subsurface conditions everywhere on the site; that is, subsurface conditions on the subject site do not vary significantly from those disclosed by the soil borings. Chemical testing was conducted by laboratories certified by the State of California Department of Health Services. The results of the chemical testing are accurate only to the degree of the care of ensuring the testing accuracy and the representative nature of the soils obtained. The findings presented herewith are based upon professional interpretation using state-of-the art methods and equipment and a degree of conservatism deemed proper as of this report date. It is not warranted that such data cannot be superseded by future geotechnical, environmental, or technical developments.

(Krazan) is requesting that the City of Bakersfield Fire Department, Environmental Services Department (CBESD) approve of this workplan for a Limited Phase II Environmental Site Assessment (ESA). Information related to the subject project is summarized below. Krazan conducted a Phase I ESA (report dated July 16, 1998) for the subject site in July 1988. According to information noted during Krazan's Phase ! ESA, the subject site was developed in 1968 as a gasoline service station. The only records of underground storage tanks (USTs) initially associated with the subject site was a letter reference tO a 550-gal10n waste oil UST. It is anticipated that a gasoline UST system was associated with the subject site during the late 1960s; however, the location of these features and whether associated subsurface structures still exist on the subject site was not known. According to records on file with the CBESD, one 550-gallon waste-oil UST (installed in 1968) and two 10,000-gallon gasoline USTs were removed from the subject site in 1994. The approximate locations of I 215 West Dakota Avenue · Clovis California 93612 · (209) 348-2200 · FAX (209) 348-2201 Offices Serving the Western United States 2498058,EA2 I I I I I i I I i I I I ! I I I I I Project No. 024-98058 Page No. 2 the former USTs and associated service station are shown on Figure 1. Regulatory records indicated that the two 10,000-gallon USTs removed in 1994 were installed in 1975. GeoResearch of Fresno California was contracted by Unocal Corporation to document the removal of the two 10,000-gallon gasoline USTs, one 520-gallon waste oil UST (it is anticipated that this UST corresponds to the previously mentioned waste oil UST), three dispenser islands, two service bays with hydraulic lifts, and a septic system. According to a Tank Closure Report prepared bY GeoResearch, dated July 11, 1994, "all observed and monitored soil with field indication of petroleum hydrocarbons was excavated." Stockpiled soil from the waste oil UST excavation was disposed of off site. Analysis of soil collected associated with stockpiled soil from the dispenser islands detected low concentrations of petroleum hydrocarbon constituents were present. These soils were aerated on-site. Analysis of soil samples collected from adjacent to the hydraulic lift locations did not detect concentrations of total recoverable petroleum hydrocarbons. Additionally, according to a Subsurface Site Investigation report prepared by GeoResearch, dated June 7, 1993, "information pertaining to the removal of the old USTs or the installation of the new USTs is apparently not available". Based on the absence of information regarding the fate of the late 1960s gasoline USTs (assumed to have been located on-site), it is possible that the late 1960s USTs remained at the subject site. Based on the unknown status of the late 1960s USTs, Krazan recommended that additional investigation be conducted. On July 24, 1998, Krazan contracted with Maverick Environmental Services (Maverick) of Simi Valley, California to conduct a geophysical survey at the subject site. During the geophysical survey, Maverick identified the former (1994) UST excavation and an anamolous excavation at the subject site. The locations of the excavations identified by Maverick are shown on Figure 2. Based on the size and location of the anomalous excavation, it is anticipated that it may be a former location of the late 1960s USTs previously associated with the subject site. No existing USTs were identified by the July 24, 1998 geophysical survey at the subject site. Based 'on the fact that an anamolous excavation is currently located on the subject site, Krazan recommended that a Limited Phase II ESA' be conducted for property transaction purposes. Information' regarding the Limited Phase II ESA is listed below. KRAZAN & ASSOCIATES, INC. Offices Serving the Western United States 2498058.EA2 I I I I I I I I I I i I I I I I I I Project No. 024-98058 Page No. 3 The property is owned by Unocal Corporation, located at 2000 Crow Canyon Place, Suite 400, San Ramon, California 94583. The contact person is Mr. Bob Links of Unocal Corporation. Mr. Links' telephone number is (602) 200-4561. The project manager for this investigation will be Mr. Arthur H. Morrill, RG No. 5383. The address of the site is 2502 Ming Avenue, Bakersfield, California. The Assessor's Parcel Number is 148-230-40. The site is located in the southwest quarter of Section 1, Township 30 South, Range 27 East, Mount Diablo Baseline and Meridian. · The site is. currently undeveloped and is unpaved. According to information provided by the California Water Service, the estimated depth to groundwater is approximately 188 feet below ground surface (bgs). The proposed depth of the soil borings is 20 feet bgs. It is not the intention of this project to advance the soil borings into saturated subsurface materials after penetrating contaminated soil. Sample depths are summarized below. Purpose of Assessment The purpose of this assessment is to determine if PHCs associated with the former 1960s gasoline USTs (anamolous excavation) are present in soils beneath the subject site. This assessment is not being conducted to characterize and define the extent of impact of PHCs associated with the former USTs. It is possible that additional soil borings and sample analyses will be required to fully assess the extent of PHCs in the soil. In addition, findings from this investigation, or subsequent investigations, may indicate the need for a groundwater assessment including the installation and sampling of groundwater monitoring wells. KRAZAN & ASSOCIATES, INC. Offices Serving the Western United States 2498058.EA2 I l I I I I I I I I I I I I I I I I I Scope of the Assessment Project No. 024-98058 Page No. 4 I~azan understands that no drilling permits will be required by the CBESD. Before the commencement of drilling activities, Underground Services Alert (USA) would be contacted to locate public underground utilities associated with USA subscribers. Two soil borings will be advanced to approximately 20 feet bgs within the limits of the anamolous excavation. The proposed soil boring locations are shown on Figure 2. The soil borings will be drilled with a truck-mounted drill rig. Soil samples will be obtained for logging purposes in the borings at five foot intervals, beginning at five feet bgs. Soils would be logged in accordance with the Unified Soil Classification System. Sampling will be conducted by means of a split-spoon sampler containing three 6-inch long by 2-inch diameter brass sleeves. Two soil samples from each soil boring will be submitted for analysis of PHCs. Soil samples obtained from the borings will be analyzed for benzene, toluene, ethylbenzene, xylenes (BTEX) and methyl tertiary butyl ether (MTBE) by EPA Method 8020, total petroleum hydrocarbons as gasoline (TPH-G) by EPA Method 8015M. Documentation related to precision and accuracy of analytical methodology will be provided. During the boring process, soil samples will be subjectively analyzed for odor and discoloration. Additionally, the soil would be field screened with a portable photoionization detector (PID). The PID reading would be recorded on the soil boring log. The PID is a direct reading real-time analyzer that can detect most of the volatile hydrocarbon constituents present in the vapor phase of petroleum-affected soils. If no positive PID readings are noted during the drilling process, the boreholes will be backfilled with drill cuttings. In the event positive PID readings, petroleum hydrocarbon odors, or apparent petroleum discoloration are observed during drilling, the drill cuttings (soil) will be temporarily contained in DOT-approved steel 55-gallon drums. The borings would then be backfilled with bentonite chips or sand/cement slugry. Field work would be conducted by individuals meeting the Occupational Safety and Health Administration requirements for hazardous waste work including 40-hour health and safety tr~aining and medical monitoring. The work would be completed under standards set forth by industry and deemed acceptable by various regulatory agencies. Hard hats, protective eyewear, steel-toe boots, protective clothing, and respiratory devices will be worn by field personnel when deemed appropriate 'by the field engineer or geologist present.

It is anticipated that the field work will be completed in one day depending on subsurface conditions encountered. Analysis of soil samples will be completed in approximately ten working days following submittal to the laboratory. A report will be completed and submitted to Big "O" Tire Company and the CBESD in approximately ten working days following receipt of the analytical results from the laboratory. Limitations This workplan was prepared in accordance with generally accepted stmxdards of environmental practice in Kern County at this time. The sampling and testing will be conducted solely for the purpose of evaluating environmental conditions of the soil with respect to the presence of petroleum constituents at the depths and locations sampled. No soil engineering or geotechnical implications are stated or should be implied. Evaluation of site conditions for the purpose of sampling and testing will be made from a limited number of observation and sampling points. Subsurface conditions may vary beyond the data points available and it is not possible to account for these variations, despite exhaustive additional testing.

Dear Mr. Berg: Thank you for submitting the work plan for the limited Phase II Environmental Site Assessment to be performed at 2502 Ming Avenue, Bakersfield. This site assessment is being accomplished as part of an overall property evaluation, as we understand it, at the request of Big "O" Tire Company. This site assessment therefore, is not the result of a regulatory action. This office does appreciate a copy of the work plan for information purposes, however, we are not currently overseeing this project. This office would oversee environmental projects within the city, if the investigation or clean up were conducted as part of a regulatory action. Since this office is not overseeing the project, it would not be appropriate to approve the work plan. We must therefore respectfully decline your request to approve the work plan for project number 02498058. This in no way limits your ability to complete the work described in your work plan, or any other investigatory work associated with this site. If in your investigation, you do discover contamination, then, there is a requirement to notify this office. At that point, a regulatory action could be initiated which would then involve this office. Thank you again for submitting your work plan. Sincerely, REH/dln cc: H.

I i I i I Project No. 024-980 l 6 Appendix B Page No. 1 METHODOLOGIES Soil borings were advanced by a truck-mounted drill rig utilizing hollow-stem auger. Drilling fluids were not used while advancing the borings. Soil boring samples were obtained for logging purposes at five foot intervals, beginning at 5 feet bgs. Soils were logged in accordance with the Unified Soil Classification System. Sampling was conducted by means of a split-spoon sampler containing three 2- inch diameter brass sleeves. During the drilling process, soil samples were subjectively analyzed for odor and discoloration. Additionally, soils were field screened with a portable photoionization detector (PID). The PID readings were recorded on soil boring logs. The PID is a direct reading real-time analyzer capable of detecting most of the volatile hydrocarbon constituents present in the vapor phase of petroleum- affected soils. Following sample retrieval from the soil borings, Teflon® film was placed over both ends of each sleeve. Each sleeve was sealed with tight fitting plastic caps that were secured with adhesiveless tape. Samples were labeled with the project number, the sampler's initials, the boring number, and the time and depth at which the sample was obtained. Following sample labeling, each sample was placed into an ice chest and maintained at a temperature of approximately 4° Celsius with synthetic ice, to limit the volatilization of any PHCs present. Equipment used for the advancing of soil borings and the sampling of soils was decontaminated (steam-cleaned, TSP, lab-grade detergents, etc.) before arriving on-site, between each boring and/or smnpling, and before leaving the site each day, or as necessary to minimize the chances of cross-contamination. Field work was conducted by individuals meeting the Occupational Safety and Health Administration (OSHA) requirements for hazardous waste work including 40-hour health and safety training and medical monitoring. The work was completed under standards set forth by the industry and deemed acceptable by various regulatory agencies. Hard hats, protective eye wear, steel-toe boots, protective clothing, and respiratory devices were worn by field personnel when deemed appropriate by the field engineer or geologist present.
