Throughout the conduct of operations within the permit area, the Colorado Division of Wildlife will be consulted to insure that the expectations of the wildlife plan are being realized. As necessary, modifications will be made, in cooperation with this agency to further minimize disturbances and adverse impact on fish and wildlife and related environmental values and to further enhance these resources, where practical. Protection of Hydrologic Balance Sunbelt intends to utilize a drainage and sediment control plan to minimize any changes to surface water quality and to the prevailing hydrologic balance in both the permit and adjacent areas. The primary method for erosion, sediment and drainage control will be to disturb no more area at the mine, by promptly reclaiming any disturbed areas, by promoting prompt vegetation, by trapping sediment and by detaining runoff as close to the disturbed areas as possible. Diversion • structures are planned at the locations shown on the Drainage and Sediment Control Plan Map (Map 6) and will serve to divert water from the disturbed areas into a sedimentation pond. Temporary structures are designed and will be maintained to handle the amount of runoff from a 10-year, 24-hour precipitation event and will be constructed using proper roughness characteristics, maintenance of appropriate gradients, revegetation, channeling or detention basins, or a combination of one or more of these measures. They will also be maintained to the extent possible to prevent contributions of suspended solids to runoff outside the permit area. The drainage control from such facilities as roads, parking lots, surface support facilities, coal handling facilities and other structures will be an important factor in minimizing contributions of sediment outside the permit area. All such facilities will be designed, built, and maintained to provide for proper handling of runoff. 2.05-46
