All AST-petroleum storage tanks used by this facility are constructed of steel and some are <br /> concrete clad, in accordance with industry specifications as described above. The design and <br /> construction of all bulk storage containers are compatible with the characteristics of the oil <br /> product they contain, and with temperature and pressure conditions. Piping between fixed <br /> aboveground bulk storage tanks is made of steel and placed aboveground on appropriate <br /> supports designed to minimize erosion and stress. <br /> 3.19 Fault Analysis (40 CFR 112.71 (b) <br /> There is no reasonable expectation of equipment failure which would cause a spill, based on <br /> experience. However, in a tank container failure, a potential of 12,000 gals. (volume of 1 tank) <br /> could be released and ultimately flow east and south to adjacent property. An equipment <br /> failure resulting in a spill is unlikely but if it occurred, would flow in same direction as tank <br /> release. A forklift might release as much as 30 gallons of petroleum product. <br /> Table 3-7: Fuel Transfer Procedures <br /> Stage Tasks <br /> Prior to ❑ Visually check all hoses for leaks and wet spots. <br /> loading/ ❑ Verify that sufficient volume(ullage) is available in the storage tank or <br /> unloading truck. <br /> ❑ Lock in the closed position all drainage valves of the secondary <br /> containment structure. <br /> Secure the tank vehicle with wheel chocks and interlocks. <br /> Ensure that the vehicle's parking brakes are set. <br /> Verify proper alignment of valves and proper functioning of the <br /> pumping system. <br /> ❑ If filling a tank truck, inspect the lowermost drain and all outlets. <br /> ❑ Establish adequate bonding/grounding prior to connecting to the fuel <br /> transfer point. <br /> ❑ Turn off cell phone. <br /> During 1: Driver must stay with the vehicle at all times during loading/unloading <br /> loading/ activities. <br /> unloading ❑ Periodically inspect all systems, hoses and connections. <br /> ❑ When loading, keep internal and external valves on the receiving tank <br /> open along with the pressure relief valves. <br /> ❑ When making a connection, shut off the vehicle engine. When <br /> transferring Class 3 materials, shut off the vehicle engine unless it is <br /> used to operate a pump. <br /> ❑ Maintain communication with the pumping and receiving stations. <br /> ❑ Monitor the liquid level in the receiving tank to prevent overflow. <br /> ❑ Monitor flow meters to determine rate of flow. <br /> ❑ When topping off the tank, reduce flow rate to prevent overflow. <br /> 33 <br />
