IV. MINE SURFACE FACILITIES OPERATIONS PLAN <br />The Deserado underground coal mine in Rio Blanco County, Colorado provides fuel fora 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 far inclusion in the permit <br />application. Stone and Webster Engineering Company (S&W) was employed to prepare preliminary <br />design and drawings on the coal storage and transportation system. Maps, drawings and figures <br />were drawn by FBDU and S&W. Thus, some maps in the permit application contain two numbering <br />systems: (1) a continuous map numbering system, e.g., Map 24, Map 25, etc., and (2) the FBDU <br />and S&W numbering system shown on the drawings. Only the continuous map numbers are <br />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 the <br />current application is projected to produce approximately 3,200,000 tons of ROM coal per year or <br />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 wet <br />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 the <br />"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 />Permit Renewal #4 (1/2004) IV-1 <br />
