22 March 1999 <br /> AGE-NC Project No. 99-0559 <br /> Page 2 of 3 <br /> Prior to removal of the USTs the tanks were inspected and prepared for removal by Oil <br /> Equipment Service. The liquid contents of the USTs were removed. Approximately 3,100 <br /> gallons of water was pumped from tank #6 and shipped under manifest to Industrial Services Oil <br /> Company in Los Angeles, California (State Manifest Document No. 98891849, 98891851) by <br /> Nor Cal Oil of Turlock, California. <br /> An inspector from the SFP was on site to oversee the tank removal activities. After removal, the <br /> tanks were visually inspected and appeared to be intact, with no holes or extensive corrosion <br /> noted. <br /> An excavator was used to excavate the USTs, and was used to lift the USTs onto a waiting <br /> transportation vehicle to be delivered for treatment and disposal. The tanks were subsequently <br /> transported to West Coast Equipment Company of Turlock for disposal. <br /> Soil removed to uncover the tanks was backfilled and compacted in the UST excavation. Pea <br /> gravel was also used for backfill. <br /> SOIL SAMPLING <br /> Following removal of the tanks, an excavator was used to collect soil samples from 2 feet below <br /> the ends of the former USTs (Figure 2). A total of four soil samples were collected from the base <br /> of the USTs. Two soil samples were collected from the soil stockpile. Each soil sample was <br /> collected by physically pushing a new brass sleeve, pre-capped on one end, into the specified <br /> soil. The ends of the soil-filled brass sleeves were sealed with Teflon sheets and plastic end caps <br /> and were taped to preserve sample integrity. <br /> The samples were collected by AGE personnel and were labeled and placed in a chilled <br /> container. The samples were transported by California Overnight under chain-of-custody to <br /> McCampbell Analytical Inc. of Pacheco, California, a State of California Department of Health <br /> Services (DHS)-certified laboratory. The date and time the soil samples were collected were <br /> noted on the chain-of-custody form included with the attached laboratory report and quality <br /> control data. <br /> The soil samples were analyzed for: <br /> • Total petroleum hydrocarbons quantified as gasoline (TPH-g) in accordance with EPA <br /> Method 8015 Modified, <br /> Advanced GeoEnvironmental,Inc. <br />
