Threatened and Endangered Species. Since no state or federally listed • threatened or endangered animal species have been reported to occupy the area of surface operations and facilities within the permit area, impacts on such species from mining will not occur. Aquatic Biota. Because of the small extent of surface disturbance to be used by the Coal Gulch Mine, any impact of the activities on downstream aquatic communities will be minimal or non-existent. As set forth in Section 2.05.3, a detailed sediment and drainage control plan will be implemented so that any discharge from the disturbed area will meet the applicable effluent limitations prescribed by the Colorado Department of Health, Water Quality Division. Given the installation of sedimentation control structures, the employment of such control devices pursuant to this application will result in the enhancement of aquatic biology both within the permit and adjacent areas. Implementation of the 30 milligrams per liter standard required by the NPDES permit should result in no increase in total suspended solids to the downstream waters. • Wildlife Protection Procedures. Although underground mining and its related surface disturbance are not expected to impact upon the wildlife in any significant manner in this area, several protection procedures will be initiated during future mining to protect any wildlife that might be found within the area adjacent to the surface support facilities. No surface blasting will be conducted as part of the operations. Off-road vehicle use of the permit area will be kept to a minimum. Only authorized travel in the area will be permitted, and no unauthorized vehicles will be allowed on the site. Human pets, such as dogs, will be kept under control on the permit area to decrease the disruption to wildlife. Because of the steep slopes surrounding the planned surface support facilities, human travel by foot • in the area is highly unlikely. 2.05-42
