Several other out buildings are also present on <br /> the site. <br /> On March 17, 1999, three gasoline UST's were removed under permit from the site. Soil <br /> samples collected at the tithe of removal showed low concentrations of Toluene, Ethyl <br /> Benzene, Xylene and gasoline range hydrocarbons are present in the soil at the south egad of <br /> the center tank CM-2 S)• All other samples collected were non-detect. None of the <br /> oxygenated fuel compounds were detected. <br /> 2.0 PROPOSED 11qWSTIGATION <br /> Soil Disposal&E cAvation Backfill <br /> Prior to begitzt g any investigation work at the sito,the excavation for the USTs need to be <br /> backfilled. The work will be performed as follows: <br /> 1. The stockpiled soil that samples SP-3A'& SP-3$ were collected from should be <br /> transported to an appropriate facility to be disposed of <br /> 2. The other stockpiled soil from the excavation can be used to back fill that excavation <br /> sine bath the stockpiled:soil samples tested non-detect for pelroleurn hydrocarbons. <br /> Some additional clean fill will need to be brought in. <br /> Soil &Grvundwater Investigation <br /> The purpose of this investigation is to determine if the soil contamilkation is high enouo and <br /> extends to a depth to warrant further work. <br /> To accomplish this goal, GTI proposes to install one borehole at the site to a depth of f60 <br /> feet below grade. This boring will be named SB-1 and will be located immediately south of <br />
