disturbed site. Sediment control of the disturbed area will be maintained duringrevegetation <br />according to the measures described above. Drill site seed mix, shown in Tablet/-10, is broadcast <br />seeded and raked in. Access to the hole is necessary to monitor the success of the de-gassing <br />effort. Access roads used during drilling and monitoring of vent holes will be scarified and <br />reseeded next fall after such access is no longer required. <br />III.A.9 Underground Transaortation Rubber tired vehicles are used to carry personnel and <br />supplies from the surface to the underground mining area. <br />Coal is transported from the working areas by belt conveyors. The slope conveyor delivers the <br />coal to the surface coal handling facilities. <br />III.B Surface Support Facilities <br />Before the run-of-mine (ROM) coal can be shipped to the power plant, all or part of it is processed <br />in a preparation plant to remove some of the impurities. Coal handling and preparation facilities <br />have been constructed in the SE1/4, Sec. 4, T2N, R101 W (Maps 1 and 2). <br />• 111.6.1 Coal Handling and Storage The ROM coal is transported out of the mine portal on a <br />54-inch conveyor belt. A series of conveyors then transports the coal through the various storage <br />and preparation facilities. All conveyors are partially covered or totally enclosed to reduce dust <br />emissions and protect the belt from the weather. ROM coal is delivered directly to the rotary <br />breaker. <br />In the rotary breaker, large rocks and foreign material are removed from the ROM coal. The raw <br />coal is then placed on a conveyor and transported to twin 10,000-ton raw-coal silos from which <br />the coal is delivered via conveyor either to the coal preparation plant for cleaning or, quality <br />permitting, directly to the 25,000-ton slot storage. <br />After processing in the preparation plant, the clean coal is transported by conveyor to the <br />25,000-ton slot storage facility to await shipment to the power plant. A sampling system and scale <br />are provided between the preparation plant and the slot storage. <br />III.B.2 Coal Preaaration Plant The preparation plant processes the ROM or raw coal through a <br />mechanical gravity separation process. A fine coal froth floatation circuit is available to increase <br />Permit Renewal #3 (Rev, 8/99) III-29 <br />
