erosion. Backfilling and grading will be completed as soon as feasible after the mining <br />process is complete. <br />Maximum slopes and slope combinations will be compatible with the configuration of <br />surrounding conditions and selected land use. Mining will occur at a slope that is stable. <br />The site will be reclaimed to grades consistent with pre -mining elevations. <br />The operator will backfill using fill material generated on-site, or imported inert fill <br />generated outside the permit area. If any inert off-site material is used as backfill, a <br />notarized letter will be submitted to the Division as required by Section 3.1.5(9) of the <br />MLRB Construction Material Rules and Regulations. <br />It is not anticipated that mining will uncover any refuse or acid-forming or toxic producing <br />materials, however if any such materials are encountered the operator will take precaution <br />to handle the materials in a manner that will control unsightliness and protect the drainage <br />system. <br />Drill or auger holes that are part of the mining operation shall be plugged with non- <br />combustible material, which shall prevent harmful or polluting drainage. Any test pits, soils <br />boring holes, or monitoring wells not located within the mine excavation limits will be <br />plugged as soon as it can be confirmed that they are no longer needed for the operation. <br />Mined material to be disposed of within the affected area will be handled in such a manner <br />so as to prevent any unauthorized release of pollutants to the surface drainage system. <br />No unauthorized release of pollutants to groundwater shall occur from any materials <br />mined, handled or disposed of within the permit area. <br />Section 3. L& Water -General Requirements The Operator will comply with applicable <br />Colorado water laws goveming injury to existing water rights and with applicable state and <br />federal water quality and dredge and fill laws and regulations. <br />The operator will develop and comply with a stormwater management plan and will use <br />best management practices (BMPs) to ensure groundwater and surface water are <br />protected to the greatest possible extent. BMPs include schedules of activities, <br />prohibitions of practices, maintenance procedures and other management practices to <br />prevent or reduce the pollution in runoff from the site. <br />Section 3.1.7 Groundwater - Specific Requirements The Operator will comply with the <br />applicable standards and conditions for classified and unclassified groundwater. <br />Section 3. L8 Wildlife. The mining and reclamation plans have been designed to account <br />for the safety and protection of wildlife on the mine site. The Operator will use concurrent <br />reclamation methods to minimize the impact on wildlife. The proposed reclamation plan <br />may improve wildlife habitat. The proposed seed mix and plantings will create improved <br />cover, foraging, roosting, and nesting areas for wildlife. The water area within the reservoir <br />will serve as habitat for waterfowl and other bird species and the fringes of the reservoir <br />will be used by mammal, bird, reptile and amphibian species.
