West Elk Mine 2.05.5 Post-Mining Land Uses The pre-mining and adjacent land use is rangeland and wildlife habitat. It is desired to provide final reclamation of the disturbed areas that is self-sustaining and provides habitat suitable for domestic livestock and wildlife. As a result of concentrating the refuse disposal to as few acres as possible, only minimal impact Will occur. The disposal areas will occupy a maximum of approximately 65 acres. Refuse disposal will occupy less than one percent of the total 40-year mine plan area (Exhibit 50, Exhibit 51 and Exhibit 52). Post-mining topography of the affected area is indicated on Map 58 and Map 59. Except within the landslide area (if the upper refuse disposal site is constructed) and the lower refuse disposal site described in Exhibit 51, the reclaimed slopes will be similar to the pre-mining topography or less, if necessary, to assure a 1.3 factor of safety after reclamation. Cut-and-fill terraces are not anticipated nor proposed at this time. Rangeland and wildlife habitat was selected as the post-mining land use for the refuse disposal areas because of the pre-mining conditions in the area. Reclamation at the West Elk Mine will provide grazing for livestock as well as develop cover, food, and nesting areas for wildlife. The surrounding heavily shrubbed areas and clusters of planted shrubs will provide adequate edge effect to assure. a diverse wildlife habitat within a rangeland meadow plant community. 2.05.6 Mitigation of Surface Coal Mining Operation Impacts Air Pollution Control Plan - 2.05.60) Air quality protection will be provided by the following measures: Conveyor Svstenis All conveyors outside the mine portal are designed to prevent particulate dispersion of coal by wind. That portion of the loadout conveyor over the North Fork of the Gunnison River is totally enclosed to prevent discharge of coal dust to the river. Water sprays, using surfactant if appropriate, have been mounted at key transfer points to minimize dust generation from conveyors, if needed. Loadout The loadout uses a telescoping chute to load railroad cars, to help prevent dust generation and eliminate spillage. Transfer Points All transfer points between conveyors, screens, crusher, rotary breaker, and silo(s) are designed to control particulate emissions from these sources, it needed. Fuzithi e Dust Water is applied to any active unpaved roadways, parking areas, and refuse disposal area to control io dust emissions from these areas, if required, on a seasonal basis. 2.05-101 Revised June 200.1 PRIG, Rev.
