(Fluor Daniel GTI) was contracted by Texaco Refining and Marketing Inc. (TRMI) to witness the removal of four underground storage tanks (USTs) at their facility No. 61-058-0988. The facility is located at 3621 California Avenue in Bakersfield, California (Figures I and 2). K.E. Curtis was the general contractor for the project and Mr. Steve Underwood represented Bakersfield City Fire Department Environmental Services (BCFDES). Soil samples were collected following UST removal activities to determine if hydrocarbons were present in soil beneath the USTs. This report presents site background, assessment procedures, sampling protocol, and the findings of the assessment. 2.0 BACKGROUND In 1983 four steel USTs (three 12,000-gallon gasoline USTs, and one 8,000-gallon diesel UST) were installed (Figure 2 and Table 1). On September 17, 1989, hydrocarbon impacted soil was encountered during excavation of the UST vent lines. On September 18, 1989, Groundwater Technology collected 7 soil samples from within the excavation. The samples were analyzed for benzene, toluene, ethylbenzene, and total xylenes (BTEX), and total petroleum hydrocarbons as gasoline (TPHG). Concentrations of BTEX and TPHG were detected in two samples in the vicinity of the northernmost gasoline UST (regular tank). On September 20, 1989, approximately 60 cubic yards of soil was removed from the vent line excavation and between the unleaded and supreme unleaded USTs. Two confirmation samples were collected. TPHG was detected at an approximate depth of 15 feet (between the unleaded and supreme unleaded USTs) at a concentration of 8,600 mg/kg. All excavated soil removed and with clean backfill. was replaced On January 22 through 23, 1990, five soil borings were drilled to determine the lateral and vertical extent of hydrocarbon contamination beneath the USTs. One boring (B1) was drilled between the unleaded and supreme unleaded USTs, and the other four borings (B2 through B5) were drilled around the USTs to a total depth of 40 feet. The 20 and 40 foot sample from each boring was analyzed for BTE× and TPHG. No hydrocarbons were detected. 3.0 GEOGRAPHY/HYDROGEOLOGY The is located in the north/central of Bakersfield. The elevation of the is facility portion approximate facilrty 390 feet above sea level and topography in the region is essentially fiat (Figure 1). The Kern River is present approximately %-mile to the north. The facility is located in a commercial area. The facility is located on the alluvial plain of the Kern River. Sediments underlying the region consist of fluvial deposits including silt, sand and gravel (CDMG, 1964). Sediments encountered during the ! UST Removal Report Page 2 I TRMI Facilit~ No. 61-058-0988 June 4, 1997 excavation consist pdmadly of fine- to coarse-grained sand and sandy silt. An unconfined aquifer is present below the site at a depth of approximately 155 feet. The gradient is toward the southeast (KCWA, 1996). 4.0 EXCAVATION AND UST REMOVAL ACTIVITIES On May 20, 1997, K.E. Construction prepared the four USTs for removal. The USTs were rinsed and degassed by Adams Service, Inc. of Gardena, California. UST rinsate was transported, accompanied by a state Uniform Hazardous Waste Manifest, to DeMenno-Kerdoon in Compton, California for recycling. A copy of the rinsate manifest is provided in Appendix A. After dry ice was placed in the USTs readings of the lower explosive limit (LEL) and oxygen (02) were taken from each tank periodically. When LEL and O2 readings sufficiently decreased to BCFDES requirements (LEL <4% and O2 <10%), Mr. Underwood of BCFDES removal of the USTs. Table 1 summarizes UST information details. approved Upon removal, the USTs were visually inspected to determine their external condition and structural integrity. The gasoline USTs were intact and no holes were observed. The diesel UST had two holes visible on the south side near the fill-end of the tank. These holes were only visible after the UST was subjected to several blows from a sledge-hammer during the removal of soil on the UST. The USTs were removed and loaded onto flatbed trailers for transportation to Adams Steel located in Anaheim, California for destruction. UST Certificate of Destruction is included in Appendix A. Following tank removal, a trac-hoe was used to retrieve soil samples from a depth of 2 and 6 feet beneath the former USTs (Figure 2). Due to the close proximity of the piping to the excavation, BCFDES waived the required sampling beneath the product piping. After overlying soil was removed to the target depth, the back-hoe bucket was used to retrieve a relatively undisturbed soil sample. Soil samples were then collected by driving a stainless-steel sample tube into the soil near the digging teeth of the bucket. The sample tube was filled such that no significant headspace was left at either end of the tube. Each sample tube was sealed at each end with a teflon sheet, a plastic cap, and tape to secure the plastic cap. The samples were labeled to indicate date and time of sample collection, sample location and depth of the sample, project location, and the sampler's name. They were then placed on ice in an ice chest and hand- delivered to Transglobal Environmental Geochemistry (TEG), an onsite mobile lababoratory. The sample locations were approved by Mr. Underwood of BCFDES. $.0 SOIL SAMPLE ANALYTICAL RESULTS The samples collected beneath the gasoline USTs were analyzed for benzene, toluene, ethylbenzene, and total xylenes (BTEX), and total petroleum hydrocarbons as gasoline (TPHG), using EPA method 8020 and 8015-modified, respectively (Table 2). Soil samples collected beneath the diesel UST were analyzed for BTEX and total petroleum hydrocarbons as diesel (TPHD), using EPA method 8020 and 8015-modified, UST Removal Report Page 3 TRMI Facility No. 61-O58-0988 June 4~ 1997 respectively. BTEX, TPHG, and TPHD were not detected. Complete laboratory reports and chain-of- custody documents are presented in Appendix B. 6.0 WASTE MANAGEMENT Four samples (SP1 through SP4) were collected for waste profiling purposes from approximately 200 yd3 of excavated soil and analyzed for BTEX, TPHG, and TPHD. No hydrocarbons were detected. The analytical results are provided in Table 2. According to Mr. Tim DeVusser of K.E. Curtis the approximate 200 yd3 of clean excavated soil was transported to a vacant lot located at 3264 California Avenue. 7.0 CONCLUSIONS No hydrocarbons were detected beneath the former USTs. Therefore, there is no threat to the environment or underlying unconfined aquifer. TRMI respectfully requests confirmation from BCFDES that no further action is necessary with respect to the UST removal at this facility.

November 12, 2003 DELTA Project No. PA3621C-G Mr. Steve Underwood. City of Bakersfield Fire Department Preventative Services 1715 Chester Avenue, 3ra Floor Bakersfield, California 93301 Re: GRASP SITE ASSESSMENT REPORT Texaco Service Station 3621 California Avenue Bakersfield, California Dear Mr. steve UnderwoOd: Delta Environmental Consultants, Inc. (DELTA) [formerly KHM Environmental Management, Inc.] on behalf of Equilon Enterprises LLC dba Shell Oil Products US (SHELL) has prepared this GRASP Site Assessment Report for the above referenced site (Figure 1). The Groundwater Assessment Program (GRASP) activities initiated at the above referenced site on September 15, 2003, revealed no detectable concentrations of petroleum hydrocarbons in the subsurface groundwater, which are detailed in this report. .BAcKGRoUND GRASP is a voluntary initiative by SHELL to install groundwater monitoring wells at numerous retail service stations nationwide that do not have any active release cases but have been identified to be in close proximity to one or more public water supply wells. The purpose ofth/s program is to proactively monitor the groundwater beneath these sites and, in the event of a subsurface release, to respond quickly to protect public wells from this impact. On January 27, 2003, DELTA supervised the drilling of one exploratory soil boring (SB-1). Groundwater was encountered at 95.5 feet below ground surface (bgs)and drilling was terminated at 100 feet bgs. No groundwater monitoring well was installed. GRASP WELL INSTALLATION On September 15, 16 and 17, 2003, DELTA supervised the drill'ing and installation of three groundwater monitor/ng _wells (MW-I, MW-2 and MW-3). DELTA obtained a well permit from the Kern County Environmental Health Services Department (Appen~x A). Well construction details are displayed in the boring logs presented in Appendix B: Well development sheets are included in Appendix C. Site survey data is included in Appe_ndix D _ac..d_ ~e_wa~te inventory record sheet_ i.s included in Appendix E..Amemberofi November 12, 2003 ~ Page 2 . ANALYTICAL FINDINGS Soil samples were Collected but not analyzed during the drilling of these groundwater monitoring wells due to low PID (photo-ionization gas detector) headspace reading (below 10 parts per million by volume). On September 25, 2003 the groundwater monitoring wells were developed. On September 30, 2003 the groundwater monitoring wells were sampled and analyzed for chemical impacts. Groundwater analytical data is summarized in Tablel and presented on Figure 2. Well monitoring data sheets are included in Appendix F. Certified analytical results and chain-of-custody documentation for groundwater are presented in Appendix G. The recommendations contained in this report represent Delta's professional opinions based upon the currently available information and are arrived at in accordance with currently acceptable professional standards. This report is based upon a specific scope of work requested by the client. The Contract between Delta and its client outlines the scope of work, and only those tasks specifically authorized by that contract or outlined in this report were performed. This report is intended only for the use of Delta's Client and anyone else specifically listed on this report. Delta will not and cannot be liable for unauthorized reliance by any other third party.

April 28, 2003' KHM Project D81-3'621 Mr. Steve Underwood City' of Bakersfield Fire Department Preventative Services 1715 Chester Avenue, 3ra Floor Bakersfield, California 93301 Re: GRASP SITE ASSESSMENT REPORT Texaco Service StatiOn 3621 California Avenue Bakersfield, California Dear Mr. Steve Underwood: KHM Environmental Management, Inc. (KHM) on behalf of Equilon Enterprises LLC dba Shell Oil Products LIs (SHELL) has prepared this GtlASP Site Assessment Report for the above referenced site (Figure 1). The Groundwater Assessment Program (GRASP) activities · initiated at the above referenced site on January 27, 2003, revealed no detectable ..concentrations of petroleum hydrocarbons in the subsurface groundwater, which are detailed in this report. i BACKGROHND GRASP is a voluntary initiative by SHELL to install groUndwater monitoring wells at numerous retail service stations nationwide that do nol} ha;~e any active.release cases but have been identified to be in close proximity to one or more public water supply Wells. The purpose of this program is to proactively monitor the groundwater beneath these sites and, I in the event of a subsurface release, to respond quickly to protect public wells from this impact. i GRASP ASSESSMENT On January 27, 2003, KHM supervised the drilling of one exploratory soil boring (SB- 1). Groundwater was encountered at 95.5 feet below ground surface (bgs) and drilling was terminated at 100 feet bgs. KHM obtained a well permit from the Kern County . Environmental Health Services Department for this exploratory soil boring (Appendix A). Exploratory boring lithology and field observations are documented in a boring log - 911 S.

The waste inventory and disposal record sheet is included as Appendix C. ANALYTICAL FINDINGS Soil samples were not ~:aken for analysis during.the drilling of this boring due to low PID (photo-ionization gas detector) headspace reading (below 10 parts per million by volume). KHM collected grab groundwater samples from this exploratory soil boring (SB- 1). Grab groundwater analytical results are summarized in Table 1 and presented in Figure 2. Certified analytical results and chain-of-custody documentation for groundwater are presented in Appendix D.
