It will be utilized to perform maintenance on the <br />larges surface equipment. As-built descriptions of the surface shop facilities are provided in Exhibit 68. <br /> <br />Materials Storage Bench Building <br /> <br />Construction of the Materials Storage Bench Building was completed in March 1996. The <br />building is utilized to store materials that will be used in the mine. The 3,900 square foot <br />building has six bays. The as-built description is provided in Exhibit 68. <br /> <br />Bulk Fuel, Barrel, and Hydraulic Component Storage Areas <br /> <br />MCC stores bulk petroleum products within a covered, concrete bunker capable of containing <br />approximately 31,000 gallons. Barrels containing petroleum products or waste materials are stored <br />within a separate covered containment area of approximately 1,840 square feet located between the <br />bulk fuel area and the Maintenance Shop. These storage areas are enclosed by three walls and a <br />roof to reduce the accumulation of precipitation within the concrete bunkers. The material stored in <br />this area includes products, recyclables, and hazardous wastes. <br /> <br />Petroleum products, as well as propane, are stored for ongoing operations and maintenance usage. <br />Recyclables are collected and transported off-site and hazardous waste is also transported off-site. <br />See the Spill Prevention, Control and Countermeasure Plan in Exhibit 8 for more detailed <br />information regarding storage of these products. The bulk fuel storage area also includes a <br />heated, enclosed storage bay for a total storage area of approximately 3,500 square feet. To the <br />west of the heated, enclosed bay is the hydraulic components storage building. This 450 square <br />foot, steel structure provides containment and cover for hydraulic components, motors, etc. being <br />stored prior to return to vendors. Dimensions of buildings and tanks are provided in Exhibit 68. <br /> <br />Oil Separation Skimming System <br /> <br />The oil separation system consists of an oil skimming pit and an oil skimmer. The skimming pit is <br />contained in the shop building and receives water from wash down bays and the shop. An oil <br />skimmer pipe allows the floating oils to be directed to oil/water separators below the shop and near <br />the silos. The remaining water is drained to the mine site sediment ponds and/or is pumped and <br />hauled to an authorized disposal facility. <br /> <br />Bulk Rockdust Bin and Compressor Building <br /> <br />MCC utilizes a bulk rockdust storage and distribution system at West Elk Mine. The #1 bulk rock <br />dust bin has a capacity of approximately 142 tons and contains the baghouse. Dust from #1 tank is <br />transferred underground. Bulk Rock dust tank #2 has a capacity of approximately 150 tons and is <br />used for additional storage only. The compressor, distribution tank and controls are contained in a <br />416 square foot building at the base of the bulk storage bin. An as-built construction description is <br />provided in Exhibit 68. <br /> <br />Water Treatment Plant <br />
