• end of the stockpile. The berm and ditch design calculations are <br />shown in Attachment F, <br />Finally, an incised sedimentation pond will be constructed and <br />maintained to provide storage for the runoff from the disturbed <br />area resulting from a 10-year, 24-hour precipitation event as <br />we 11 as for sediment storage. Sediment will be removed as <br />necessary to maintain adequate flood storage capacity. While it <br />is anticipated that this will be a non-discharging pond, a modi- <br />fication to Mt. Gunnison's NPDES Permit will be made to allow for <br />any infrequent spi}}way discharge of water from the pond into the <br />North Fork of the Gunnison River. Design calculations are <br />presented in Attachment F, cross-sections in Attachment G. <br />Sediment control for that portion of Bear Coal Company's 5-year <br />permit area not included in this proposed operation will not be <br />impacted. <br />• <br />Reclamation <br />Reclamation of the disturbed area, including the roads and stock- <br />pile area, will 6e reclaimed upon elimination of the stockpile <br />and in accordance with Section 4 of, the Mt. Gunnison MbR Plan. <br />The area will be restored to its pre-mining land use ofi rangeland <br />and wildlife habitat. If the stockpiled material is determined <br />to be~of seed-bed quality, a sufficient quantity of material will <br />be retained to reclaim the area in accordance with Section 4.4,2 <br />of the Mt. Gunnison MbR Plan. The area will be revegetated using <br />the Permanent Seed Mix described in Table 4.4,5.A of the Mt. <br />Gunnison MbR Plan. If the material is not of sufficient quality <br />to be considered seed-bed quality material suitable material will <br />be purchased from an outside source to satisfactorily retoosoil <br />the disturbed area. <br />• <br />-4- <br />
