FACILITY LAYOUT DIAGRAM - 40 CFR 112.7(a)(3) <br /> Figure 1 shows the general location of the Facility on a U.S. Geological Survey <br /> topographic map. Figure 2 presents a layout of the Facility and the location of storage <br /> tanks and drums. The diagram also shows the direction of surface water runoff. As <br /> required under 40 CFR 112.7(a)(3), the Facility diagram indicates the location and content <br /> of ASTs, transfer stations and connecting piping. <br /> 3.3. SPILL REPORTING - 40 CFR 112.7(a)(4) <br /> The discharge notification form included in Appendix D is completed upon immediate <br /> detection of a discharge and prior to reporting a spill to the proper notification contacts <br /> after evaluation by Facility Management and as applicable to limits described in <br /> Section 1.4.4. <br /> 3.4. POTENTIAL DISCHARGE VOLUMES AND DIRECTION OF FLOW - 40 CFR <br /> 112.7(b) <br /> Table 5 presents expected volume, discharge rate, general direction of flow in the event <br /> of equipment failure and means of secondary containment for different parts of the Facility <br /> where oil and/or petroleum fuel is stored, used, or handled. <br /> 3.5. CONTAINMENT AND DIVERSIONARY STRUCTURES - 40 CFR 112.7(c) <br /> Methods of secondary containment at the Facility include a combination of structures <br /> (e.g., berm and built-in secondary containment) and land-based spill response (e.g., <br /> booms and absorbents) to prevent oil and/or petroleum fuel from reaching navigable <br /> waters or adjoining shorelines. <br /> 3.5.1. Spill Pallets <br /> 55-gallon drums are kept on spill pallets. Each spill pallet, if employed, has a minimum <br /> 110% containment capacity, which can effectively contain the volume of any single <br /> 55-gallon drum or equivalent for a two drums spill pallet. <br />
