1 <br /> . Based on the results of the soil samples collected from the angled sod boring D-2, the vertical <br />' extent of impacted sod appeared limited to shallow subsurface soil The soil sample collected at <br /> 14 fleet bgs from D-2 only contained a concentration of MTBE of 0 0054 mg/kg The sod sample <br />' collected at 23 feet bgs from D-2 did not contain detectable concentrations of MTBE, BTEX or <br /> TPH-as-gasoline TPH-as-gasoline and BTEX were not detected in either soil sample collected <br /> from D-2 Only a concentration of 0 016 mg/kg of MTBE was detected in the sod sample collected <br />' at 20 feet bgs from D-1 TPH-as-gasoline and BTEX were not detected in either of the soil <br /> samples collected from D-1 <br />' On February 12, 1998, under PHS/EHD observation, L&M Construction excavated approximately <br /> 60 cubic yards of impacted sod from the vicinity of the west dispenser island The depth of the <br /> excavation ranged from approximately 7 feet near the former dispenser to approximately 12 feet <br /> beneath the former underground product distribution piping The excavated sod was stockpiled <br />' on site and remediated by passive aeration Sod sampling and analysis to confirm the excavation <br /> limits were not recorded in the regulatory case file <br /> On October 1, 1998, under PHS/EHD observation, FGL Environmental re-sampled the soil <br /> stockpile Two soil samples were collected from the accumulated soil stockpile for laboratory <br />'. composite and analysis The composite soil sample was analyzed for TPH-as-gasoline and <br /> BTEX by Modified EPA Method 8020/8015 and for oxygenates by EPA Method 8260 Based on <br /> the results of the soil sample analyses, PHS/EHD allowed the soil stockpile to be spread on-site <br />' On October 1, 1998, under PHS/EHD observation, FGL Environmental also sampled the on-site <br /> domestic well The groundwater sample was analyzed for TPH-as-gasoline and BTEX by <br />' Modified EPA Method 8020/8015 and for oxygenates by EPA Method 8260 None of these <br /> compounds were detected in the water sample Well construction details were not available The <br /> results of the domestic well groundwater analyses are summarized in Table 2 <br />' On March 25, 1999 Ramage Environmental published Underground Storage Tank Environmental <br />' Corrective Action Summary Report documenting the tank removal and subsequent corrective <br /> actions completed at the site Based on the analytical results from the sod samples collected from <br /> beneath the north end of the middle former UST, Ramage Environmental recommended that a <br />' work plan be developed to evaluate the extent of impacted soil and groundwater <br /> 5 <br /> 1 <br />
