t. <br /> L. <br /> 18 November 1998 <br /> AGE-NC Project No. 98-0483 <br /> Page 2 of 7 <br /> j (Figure 2). A domestic well is located near the southeast corner of the property, along South <br /> Lr Highway 99 Frontage Road(Figure 2). The domestic well is located approximately 200 feet east of <br /> the former UST excavation location'. <br /> Lo - <br /> 2.2. UNDERGROUND STORAGE TANK REMOVAL <br /> On 01 May 1998, one 10,000-gallon diesel UST and one 1,000-gallon diesel UST were removed <br /> from the property by.Thorpe Oil. The approximate locations of the former UST excavations are <br /> shown of Figure 2. The former 10,000-gallon UST (Tank 1) was located east of the former <br /> LW 1,000-gallon UST(Tank 2). The former fuel dispenser was located between the two USTs. During <br /> the UST removal activities,representatives of Thome Oi1,,collected a total of five soil samples from <br /> beneath the USTs and dispenser area. Soil samples were collected-from beneath each end of each <br /> UST and one soil sample was collected beneath the fuel dispenser. In addition, three soil samples <br /> were collected from the excavated soil. The soil samples were transported under chain-of-custody <br /> to GeoAnalytical Laboratories, Inc. of Modesto, California, and analyzed for total petroleum <br /> hydrocarbons quantified as diesel (TPH-d), total petroleum hydrocarbons quantified as motor oil <br /> (TPH-mo)and purgeable aromatic hydrocarbons(benzene,toluene, ethylbenzene and total xylenes <br /> [BTEX]) in accordance with EPA methods 3350(LUFT) and 8020, respectively. <br /> Table 1 <br /> � Summary of Soil Analytical Detections <br /> Underground Storage Tank Removal Samples' <br /> 01 May 1998 <br /> L. <br /> Sample D TPH Diesel.
