ATC SITE SAFETY PLAN <br /> FACILITY BACKGROUND <br /> Prior to July 1984, one 550-gallon waste oil UST, identified as Tank #4, was emptied of <br /> product, filled with sand, and capped with concrete. In November 1986, one 1,000-gallon <br /> regular gasoline UST, identified as Tank #3, was removed and disposed of. Soil sample <br /> collected during the removal of Tank #3 contained elevated concentrations of petroleum <br /> hydrocarbons. In May 1989, one 1,000-gallon unleaded UST, identified as Tank #1 was <br /> filled with five cubic yards of concrete. Currently two USTs, identified as Tanks #2 and #5, <br /> remain in place and are in operation. <br /> WORK PLAN <br /> Task One: <br /> Supervise the installation of one soil boring to an estimated depth of approximately <br /> 80 feet. The boring will be advanced until three consecutive soil samples that <br /> contain no physical evidence (odor, PID readings, etc.) of petroleum hydrocarbons <br /> are collected. At least two soil samples and possibly one groundwater sample will be <br /> collected from the boring from areas which exhibit physical indications of <br /> contamination or significant changes in lithology. Samples will be analyzed for <br /> BTEX (EPA Method 8020), TPHg (EPA Method 8015 Modified), oxygenate fuel <br /> additives (EPA Method 8260), and total lead. <br /> PACE 4 <br />
