r <br /> 09 December 1996 <br /> AGE Project No. 96-0263 <br /> Page 2 of 3 <br /> Inc. of Silver Springs, Nevada (State Manifest Document No. 96414882) by Norcal Oil of <br /> Turlock, California. <br /> Inspector William Robinson of the City of Tracy Fire Department was on hand to oversee the <br /> tank removal activities. <br /> After being removed, the tanks were visually inspected and appeared to be intact, with no holes <br /> or extensive corrosion noted. The tanks were subsequently transported to 'West Coast Equipment <br /> Company of Turlock for disposal. <br /> SOIL SAMPLING <br /> Following removal of the tank, a backhoe was used to collect a soil sample from 2.feet below th4 <br /> ends of the formef USTI (Figure 2). One soil sample was collected from the area of the former, <br /> dispenser and one soil sample was collected from the mid-section of the dispenser lines. Soil <br /> samples were collected from the soil stockpile to be composited. Each soil sample was collected <br /> with metric soil sampling hammer. loaded .vith a pre-cleaned brass sleeve. The ends of the brass <br /> sleeves were sealed with a Teflon plastic and end caps were tapped over the ends of each sample <br /> sleeve. <br /> Samples were collected by a representative of McCampbell Analytical Inc. (MAI) of Pacheco, <br /> California, a state-certified analytical laboratory. The samples were labeled and placed in a <br /> chilled container for subsequent transport to MAI. The date and time soil samples were taken <br /> were noted on the chain-of custody form included with the attached laboratory report and quality <br /> control data. <br /> The samples associated with the UST, dispenser and the soil spoils pile were analyzed for total <br /> petroleum hydrocarbons quantified as gasoline (TPH-g), purgeable aromatics (benzene, toluene, <br /> ethylbenzene and total xylenes: BTE&X) and methyl tertiary butyl ether (MTBE) in accordance <br /> with EPA methods 8015-modified for gasoline and 8020 for BTE&X and MTBE. Each soil <br /> sample was analyzed of total lead in accordance with EPA methods 6010 for soils. In addition, <br /> the sample collected from the mid-dispenser line was analyzed by EPA method 8240 to <br /> determine if chlorinated hydrocarbons were present. <br /> RESULTS <br /> TPH-g, BTE&X and MTBE were present in each of the samples analyzed in concentrations <br /> exceeding the method detection limits. TPH-g was detected in the soil samples has high as 3,400 <br />
