6 6 <br /> F. Spill Potential: <br /> The oil filled equipment, storage containers, spill prevention techniques <br /> currently utilized and the potential for ail spills are described in this <br /> section. Small spills occurring during normal operation will be contained <br /> and cleaned up in accordance with Section 5H, of this Emergency Plan. <br /> 1) Underground Waste-Oil Storage Tank <br /> a) The facility has one 1,000-gallon underground tank used for <br /> storing waste oil from garage maintenance operations, and it is <br /> located southwest of the Garage Building. The tank is a <br /> double-walled fiberglass-clad steel tank which is compatible <br /> with the stored fluid. The tank and associated piping have a <br /> continuous leak monitoring system, one located in the tank's <br /> annular space and one in the pipeline collection sump, which <br /> activates an audible and light alarm in the Garage Building. <br /> If an alarm is activated, an assessment to determine the cause <br /> will begin and may include leak testing. The waste oil in the <br /> tank is pumped out by a licensed recycler every 90 days, or <br /> before it gets full. The Garage Foreman is responsible for the <br /> tank and its contents. <br /> Possible Spill Occurrence: <br /> i) Overfilling: The waste oil tank inlet is located inside <br /> the Garage Building. No more than 5 gallons <br /> could be spilled, and spilled oil would stay <br /> confined within the building. <br /> ii) Oil Removal: There is an overfill box at the tank removal <br /> pipe which is product-tight to contain <br /> spills during this process. The possibility <br /> of a spill during the oil removal process <br /> would be minimal. Constant supervision <br /> during the removal process and inspection of <br /> oil removal equipment minimize the <br /> possibility of a spill. The maximum <br /> potential spill would be the volume of the <br /> hose which would not exceed 6 gallons. <br /> 3-2 <br />
