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.
