Bakersfield, CA 93301 RE: Fuel System Removal Report 7-Eleven Store#16549 4647 Wilson Road Bakersfield, CA 93309 Stantec Project No.: 211502063.220.0521 Dear Mr. Wines: Stantec Consulting Corporation (Stantec) has prepared this report on behalf of 7-Eleven Inc. (7- Eleven) to document the removal of the fuel system and soil sample results obtained during the fuel system removal activities conducted at 7-Eleven Store Number 16549 located at 4647 Wilson Road in Bakersfield, California (Figures 1 and 2). This work was conducted on February 4, 2011 in accordance with the requirements of the Bakersfield Fire Department Prevention Services (BFDPS). INTRODUCTION The purpose of Stantec's project involvement was to observe and document the removal of the underground storage tanks (USTs) and dispenser fueling system by Wayne Perry, Inc. (Wayne Perry) and collect soil samples'to assess subsurface conditions beneath the former USTs and dispensers. Stantec's scope of work consisted of the following tasks: • Prepare a site-specific Health and Safety Plan for soil sampling; • Observe and document the removal and disposal of the UST rinsate, USTs, and product piping from the site; • Collect.soil samples beneath the USTs and dispensers under the direction of the BFDPS specialist; Submit the fuel-system-removal soil samples for laboratory analysis; Prepare a summary report documenting the USTs removal, waste disposal, soil sampling activities, and soil sample analytical results. Stantec March 25, 2011 Page 2 of 5 FUEL SYSTEM REMOVAL ACTIVIES Permitting Wayne Perry obtained permits to remove three 10,000-gallon capacity, double-walled steel USTs and associated product piping from the BFDPS (Attachment A). Site-Specific Health and Safety Plan Stantec prepared a site-specific Health and Safety Plan for sampling activities at the site, as required by the Occupational Health and Safety Administration (OSHA) Standard "Hazardous Waste Operations and Emergency Response" guidelines (29 CFR 1910.120). The document was reviewed and signed by Stantec personnel and subcontractors performing work at the site. Dispenser and Canopy Asbestos-Lead Survey On January 12, 2011, Stantec's field scientist performed a pre-demolition asbestos and lead- based paint survey for two fueling islands and a corrugated metal canopy. Prior to the demolition of the canopy, a licensed abatement contractor was hired by Wayne Perry to remove and dispose of any asbestos-containing materials. On January 31, 2011, the canopy was removed by Wayne Perry and was disposed of at Western Scrap Inc. of Bakersfield, California. Dispenser, Product Line and USTs Removal Activities On February 3, 2011, three 10,000-gallon double-walled steel USTs were exposed by Wayne Perry. In the year 2000, the premium grade UST located to the east side of the excavation was abandoned in place using slurry. In order for the formerly abandoned UST to be removed from the site, Wayne Perry cut open the secondary and primary walls.and removed the slurry using an excavator. The slurry was stockpiled and later disposed of offsite. Adams Services, Inc (Adams) then rinsed the middle and west side USTs. A total of 200-gallons of rinsate water was generated and transported by Adams to DeMenno/Kerdoon in Compton, California for treatment and disposal.,. On February 4, 2011, the dispenser islands, associated product lines, and USTs were exposed and removed. Adams inerted the middle and west side USTs with dry ice to reduce the Lower Explosive Limit (LEL) measurement. After confirmation by the BFDPS.specialist that the two USTs were_ properly inerted, Wayne Perry removed all three USTs from the excavation for inspection. All three 10,000-gallon, double-walled steel USTs appeared to be in good condition, with no apparent holes or cracks visually observed. The three USTs were disposed of at SA Recycling of Bakersfield, California. The fuel system product piping was disposed of at Waste Management of Carson, California. Mr. Dave Weirather of the BFDPS observed the USTs removal and directed the soil sample collection activities. UST, product piping and•rinsate water disposal documentation are included in Attachment B. Field notes detailing the fuel system removal activities are included in Attachment C. Dispenser and UST Excavation Soil Sample Collection On February 4, 2011, Stantec's field scientist collected a total of 16 soil samples in native soil. Two soil samples were collected from beneath each of the dispensers and two soil samples were collected from each end_ and .middle of the individual USTs (Figure 2). All soil samples were collected under the direct supervision of Mr. Dave Weirather, the BFDPS specialist. An excavator was used to retrieve native soil from underneath each dispenser and UST sample 16549 Fuel System Removal Report.docx stantec March 25,2011 Page 3 of 5 location. Soil samples were collected in clean, 2-inch-diameter by 6-inch long stainless-steel sample liners that were driven into the native soil held in the excavator bucket. Each soil sample was screened for hydrocarbon vapors using a portable photoionization detector (PID). The dispenser and UST soil samples,collected for analysis were retained in the stainless-steel liners, labeled, and capped with Teflon® sheets and plastic end caps. The samples were then sealed in a plastic bag, placed on ice, and transported to Kiff Analytical (Kill) laboratory located in Davis, California, accompanied by the appropriate Chain-of-Custody (COC) documentation. The soil samples were analyzed for benzene, toluene, ethylbenzene, xylenes (BTEX), total petroleum hydrocarbons as gasoline (TPHg), methyl-tert-butyl ether (MtBE), tert-butyl alcohol (TBA), diisopropyl ether (DIPE), ethyl-tert-butyl ether (EtBE), and tert-amyl-methyl ether (TAME) by Environmental Protection Agency (EPA) Method 82608. Copies of the field notes are included in Attachment C and the soil sample locations are shown on Figure 2. Stockpiled Excavation Pea Gravel Sample Collection . On February 3, 2011, Wayne Perry began stockpiling pea gravel backfill overlaying the top of the USTs and the dispenser excavation. The stockpiled pea gravel .backfill was deemed suitable by the BFDPS specialist for reuse as backfill and compaction material in the existing dispenser and UST excavation pending laboratory analysis. On February 4, 2011, Stantec's field scientist collected a total of three composite stockpile soil samples. Composite stockpile samples SP1(ABCD), SP1(EFGH), and SP1(IJKL), were collected by advancing 2-inch diameter by 3-inch long stainless-steel sample liners into the pea gravel stockpile, after removing approximately 6 inches to 1 foot of surface material in the sample location. Each stainless-steel sleeve was labeled and capped with Teflon® sheets and plastic end caps. The samples were then sealed in plastic bags, placed on ice, and transported to Kiff, accompanied by the appropriate COC documentation. The composite samples were combined in the laboratory. The four-point-composite soil samples SP1(ABCD), SP1(EFGH), and SP1(IJKL) were analyzed for BTEX, TPHg, and MtBE by EPA Method 82608. In addition the composite samples were also analyzed for total lead by EPA Method 6010B. Copies of the field notes are included in Attachment C. Dispenser and UST Excavation Backfill and Compaction On February 9, 2011, Wayne Perry performed backfilling and compaction of the dispenser and UST excavation under the direction and supervision of Korbmacher Engineering, Inc. (Korbmacher) of Livermore, California. To complete the backfill and compaction of the excavation, approximately 250 tons of original excavation pea gravel and approximately 250 tons of new imported backfill pea gravel and aggregate base (as structural backfill)were used. On February 12, 2010, Wayne Perry supervised as Bowman Asphalt of Bakersfield, California paved the site with asphaltic concrete to match the existing grade. Copies of the compaction test report are included in Attachment D. 16549 Fuel-System Removal Report.docx Alec March 25, 2011 Page 4 of 5 ANALYTICAL RESULTS Dispenser and UST Excavation Soil Sample Analytical Results The dispenser and UST soil sample analytical results are presented on Figure 2 and summarized in Table 1.

Stockpiled Excavation Backfill Sample Analytical Results The stockpiled excavation pea gravel analytical results are summarized in Table 1. TPHg, BTEX, and MtBE, were not detected at concentrations above laboratory reporting limits in the stockpile composite soil samples collected during this investigation. Total lead was reported at concentrations ranging between 1.4 mg/kg and 2.2 mg/kg in composite stockpile samples SP1(ABCD), SP1(EFGH), and SP1(IJKL). _Copies of the certified analytical reports and COC documentation are presented in Attachment E. WASTE DISPOSAL ACTIVITIES Stockpiled Concrete Slurry Disposal On February 4, 2011, approximately 115 cubic-yards of slurry generated from the removal of the formerly abandoned UST was transported by A&B Trucking and disposed of at the Bowman Asphalt Plant located in Bakersfield, California. . Copies of the waste disposal documentation for the slurry are presented in Attachment B. SUMMARY AND CONCLUSION On January 12, 2011, Stantec's field scientist performed a pre-demolition asbestos and lead- based paint survey for two fueling islands and a corrugated metal canopy. On February 4, 2011, three 10,000-gallon double-walled steel USTs and associated product piping from the site were successfully removed and disposed. No holes or cracks were observed in the piping or USTs removed from the site. The removal,of the USTs, and collection of soil samples was completed under the direction and supervision of the BFDPS specialist: On February 4, 2011, a total of 16 soil samples were collected in native soil from underneath the dispenser and UST excavations. Two soil samples were collected beneath each dispenser and two soil samples from each end and middle of'the individual USTs. Xylene was reported exclusively in soil. samples D1-1-5.0 and T3-3=20 at,concentrations of 0.0058 mg/kg and 0.076 mg/kg, respectively. Benzene, toluene, ethylbenzene, TPHg, MtBE, TBA, DIPE, ETBE, and TAME were not detected at concentrations above the laboratory reporting limits in any of the soil samples collected during this investigation. On February 4, 2011, three composite stockpile confirmation soil samples were collected from the excavated backfill material. The composite stockpile confirmation soil samples SP1(ABCD), SP1(EFGH), and SP1(IJKL) collected during this investigation did not contain detectable 16549 Fuel System Removal Report.docx Rantec March 25,2011 Page 5 of 5 concentrations above laboratory reporting limits for BTEX, TPHg, and MtBE. The composite stockpile samples contained total lead concentrations ranging between 1.4 mg/kg and 2.2 mg/kg. On February 9, 2011, Wayne Perry performed backfilling and compaction of the dispenser and UST excavation under the direction and supervision of Korbmacher. To complete the backfill and compaction of the excavation, approximately 250 tons of original excavation pea gravel and approximately 250 tons of new backfill pea gravel and aggregate base (as structural backfill) were used.
