The site is a. <br /> former Shell service station that previously included an underground storage tank (UST) <br /> complex that contained two gasoline USTs, one underground waste oil tank, and four dispenser <br /> islands. The vacant station building remains onsite(Figure 2). <br /> Site Background: The subject site is currently an active Leaking Underground Fuel Tank <br /> (LUFT) case with the SJCEHD acting as the Local Oversight Agency.
