IV. MINE SURFACE FACILITIES OPERATIONS PLAN <br /> The Deserado underground coal mine in Rio Blanco County, Colorado provides fuel for a 458-MW <br /> power plant located near Bonanza, Utah. The coal is sized and washed at the mine site. <br /> Ford, Bacon & Davis Utah (FBDU) conducted preliminary engineering for the mine's surface <br /> facilities and prepare drawings, narratives, schedules and cost estimates for inclusion in the permit <br /> application. Stone and Webster Engineering Company (S&W) was employed to prepare <br /> preliminary design and drawings on the coal storage and transportation system. Maps, drawings <br /> and figures were drawn by FBDU and S&W. Thus, some maps in the permit application contain <br /> two numbering systems: (1) a continuous map numbering system, e.g., Map 24, Map 25, etc., and <br /> (2) the FBDU and S&W numbering system shown on the drawings. Only the continuous map <br /> numbers are referenced in the written 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 <br /> area 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 <br /> the Bonanza power plant in Utah. The surface facilities described herein also provide support <br /> functions for the mining and preparation activities. The portion of the mine to be permitted under <br /> the current application is projected to produce approximately 3,200,000 tons of ROM coal per year <br /> or 16,162 tons per day (based on an average of 198 working days per year). The coal preparation <br /> facility is sized to produce 1,900,000 tons of clean coal per year. Approximately 900,000 tons of <br /> wet coal processing 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" <br /> seam portal area (also referred to as the West Portal Area and D Portal Area) is where the majority <br /> of the surface facilities are located. The "B" Portal is also located in the same facility complex as <br /> the "D" Portal and is shown on Map 15. <br /> The East Portals were developed at the east end of Scullion Gulch for ventilation. They were <br /> sealed and reclaimed in 2000 and 2001. This area is shown on Map 139. <br /> Major surface facilities designated as support facilities include the following: <br /> TR-72 (7/2019) IV-1 <br />
