IV. MINE SURFACE FACILITIES OPERATIONS PLAN <br />The Deserado underground coal mine in Rio Blanco County, Colorado provides fuel for a440-MW <br />power plant located near Bonanza, Utah. The coal is sized and washed at the mine site. <br />Ford, Bacon 8 Davis Utah (FBDU) conducted preliminary engineering for the mine's surface facilities <br />and prepare drawings, narratives, schedules and cost estimates for inclusion in the permit application. <br />Stone and Webster Engineering Company (S&W) was employed to prepare preliminary design and <br />drawings on the coal storage and transportation system. Maps, drawings and figures were drawn by <br />FBDU and SRW. Thus, some maps in the permit application contain two numbering systems: (1) a <br />continuous map numbering system, e.g., Map 24, Map 25, etc., and (2) the FBDU and S8W numbering <br />system shown on the drawings. Only the continuous map numbers are referenced in the written <br />narratives. <br />The designs had to accommodate construction and operations feasibility and environmental effects. <br />Specific attention in the environmental area was directed toward minimizing both the amount of area <br />disturbed and changes to natural drainage channels. <br />IV.A General Description <br />The surface facilities at the Deserado Mine handle and process run-of-mine (ROM) coal for use at the <br />• Bonanza power plant in Utah. The surface facilities described herein also provide support functions for <br />the mining and preparation activities. The portion of the mine to be permitted under the current <br />application is projected to produce approximately 2,600,000 tons of ROM coal per year or 13,131 tons <br />per day (based on an average of 198 working days per year). The coal preparation facility is sized to <br />produce 1,900,000 tons of clean coal per year. Approximately 700,000 tons of wet coal processing <br />waste and mine development waste may be generated annually. <br />The location and layout of the various surface facilities is indicated on Map 1. <br />Coal will be produced from the "D" seam and the "B" seam. See Section II-B, Geology. The "D" seam <br />portal area (also referred to as the West Portal Area and D Portal Area} is where the majority of the <br />surface facilities are located. The "B" Portal is also located in the same facility complex as the "D" Portal <br />and is shown on Map 15. <br />East Portals which have been developed at the east end of Scullion Gulch is used for ventilation return. <br />This area is shown on Map 139. <br />Major surface facilities designated as support facilities include the following: <br />• Mine Permit Renewal #3 (Rev. 8/99) IV-1 <br />
