West Elk Mine <br />2.05.5 Post-Mining Land Uses <br />The pre-mining and adjacent land use is rangeland and wildlife habitat. It is desired to provide final <br />reclamation of the disturbed areas that is self-sustaining and provides habitat suitable for domestic <br />livestock and wildlife. <br />As a result of concentrating the refuse disposal to as few acres as possible, only minimal impact will <br />occur. The disposal areas will occupy a maximum of approximately 65 acres. Refuse disposal will <br />occupy less than one percent of the total life-of-mine plan area (see Exhibits 50, 51 and 52). Post- <br />mining topography of the affected area is indicated on Map 58 and Map 59. Except within the <br />landslide area (if the upper refuse disposal site is constructed) and the lower refuse disposal site <br />described in Exhibit 51, the reclaimed slopes will be similar to the pre-mining topography or less, if <br />necessary, to assure a 1.3 factor of safety after reclamation. Cut-and-fill terraces are not anticipated nor <br />proposed at this time. <br />Rangeland and wildlife habitat was selected as the post-mining land use for the refuse disposal areas <br />because of the pre-mining conditions in the area. Reclamation at the West Elk Mine will provide <br />grazing for livestock as well as develop cover, food, and nesting areas for wildlife. The surrounding <br />heavily shrubbed areas and clusters of planted shrubs will provide adequate edge effect to assure a <br />diverse wildlife habitat within a rangeland meadow plant community. <br />2.05.6 Mitigation of Surface Coal Mining Operation Impacts <br />Air Pollution Control Plan - 2.05.60) <br />Air quality protection will be provided by the following measures: <br />Conveyor Systems <br />All conveyors outside the mine portal are designed to prevent particulate dispersion of coal by wind. <br />That portion of the loadout conveyor over the North Fork of the Gunnison River is totally enclosed <br />to prevent discharge of coal dust to the river. Water sprays, using surfactant if appropriate, have <br />been mounted at key transfer points to minimize dust generation from conveyors, if needed. <br />Loadout <br />The loadout uses a telescoping chute to load railroad cars, to help prevent dust generation and eliminate <br />spillage. <br />Transfer Points <br />All transfer points between conveyors, screens, crusher, rotary breaker, and silo(s) are designed to <br />control particulate emissions from these sources, if needed. <br />Fuzitive Dust <br />Water is applied to any active unpaved roadways, parking areas, and refuse disposal area to control <br />dust emissions from these areas, if required, on a seasonal basis. <br />2.05-101 Revised 06/05, 03106,04106 & 05106- PR70;1 ]/06- TR107; 09107& 02108-PR12; 04109- TR117
