I. West Elk Mine 2.05.5 Post-Mining Land Uses ~ \~ _ o The pre-mining and adjacent land use is rangeland and wildlife habitat. It is desired to provide final reclamation of the disturbed azeas 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 azeas will occupy a maximum of approximately 65 acres. Refuse disposal will occupy less than one percent of the tota140 yeaz mine plan azea (Exhibit 50, Exhibit 51 and Exhibit 52). Post-mining topography of the affected azea is indicated on Map 58 and Map 59. Except within the landslide azea (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 azea. 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 iadequate edge effect to insure a diverse wildlife habitat within a rangeland meadow plant community. 2.05.6 Mitigation of Surface Coal Mining Operation Impacts Air Pollution Control Plan - 2.05.6(1) Air quality protection will be provided by the following measures: Convevor S st`/ ems -All conveyors outside the mine portal are idesigned to prevent particulate dispersion of coal by wind. That portion of the loadout conveyor over the North Fork is totally enclosed to prevent contamination of the stream. Water sprays, usirig surfactant if appropriate, have been mounted as necessary at transfer points so as to minimize dust generation from conveyors, if needed. Loadout -The loadout uses a telescoping chute to load railroad cars, which will help prevent dust generation and eliminate spillage. Transfer Points -All transfer points between conveyors, screen, crusher, rotary breaker, and silo(s) aze designed to control particulate emissions from these sources, if rieeded. Fu¢itive Dust - Water is applied to any active unpaved roadways, parking azeas, and refuse disposal azea to control dust emissions from these azeas, if required, on a seasonal basis. Onen Coal Stockpiles -The stockpiles aze compacted and may be sprayed as necessary to eliminate particulate emissions created during coal handling. 2.05.95 Revised Jun. 7995 PR06
