1 <br />2.0 Facility Discussion <br />This section discusses the two areas relevant to SPCC requirements at the Roaring Fork <br />Resources Mamm Creek Sand and Gravel Pit: the in pit fuel storage and the vehicle <br />maintenance shop. <br />' 2.1 In Pit Fuel and Used Oil Facilities <br />' This section discusses the in pit fueling and used oil storage facilities and potential spill <br />scenarios. This plan addresses a typical in pit scenario because the mine plan projects <br />mining one area completely prior to moving to a new pit. The fuel storage and used oil <br />facilities will therefore follow the mining sequence from pit to pit. This plan will be <br />implemented prior to placing the fuel and used oil storage facilities into service in the <br />new pit location. <br />' 2.1a In Pit Fuel Storage <br />' In pit fuel storage is provided for the following applications: <br />Description Capacity (gallons) Contents <br />' Off Road Trucks 10.000 #Z Diesel <br />Off Road Equipment 10,000 Red Diesel <br />Crusher Operations 10,000 Red Diesel <br />' Wash Plant Operatious 10,000 Red Diesel <br />These storage tanks are above ground and are single-walled steel tanks made specifically <br />' for the storage of fuel. The tanks are eight (8) feet in diameter and twenty-seven (27) feet <br />in length and manufactured by Eaton Metal. The tanks are filled through a screened <br />opening on the top. A second aperture on the top of the tanks is used as a vent and as an <br />' opening for a stick gage. <br />' The diesel tank is surrounded by a steel container that is 5 feet high, l0 feet wide, and 30 <br />feet long. The volume inside of the wall is 11,220 gallons. This vessel is constructed out <br />of steel plate, H beams and tubular sections. The components are welded together. The <br />' joints on the inside of the tank are continuously welded, thereby providing a leak proof <br />seal. Four saddles are provided for tank support. The containment vessel has an open <br />top. A valve is located in the bottom of one corner to drain the contairunent vessel of <br />' stormwater or spilled diesel fuel. <br />2.1a.1 Information Required by 40 CFR Part 112 <br />' 1. The fuel tank is contained within a steel containment vessel that is designated <br />to contain a maximum spill from the tank. The capacity of the fuel tank is <br />' 10,000 gallons and the capacity of the steel containment vessel is 11,220 <br />gallons. Thus, no prediction of direction, rate of flow, or total quantity of oil <br />is necessary as a maximum spill would be fully contained. <br />1 <br />7 <br />1 <br />
