lifts will be compacted with a sheepsfoot roller to tie lifts together. The upland areas will be <br /> reclaimed to grades consistent with pre-mining drainage patterns. <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 /> to prevent any unauthorized release of pollutants to the surface drainage system. No <br /> unauthorized release of pollutants to groundwater shall occur from any materials mined, <br /> handled or disposed of within the permit area. <br /> Section 3.1.6 Water-General Requirements: <br /> The Operator will comply with applicable Colorado water laws governing injury to existing <br /> water rights and with applicable state and federal water quality and dredge and fill laws <br /> 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 practical 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: <br /> The Operator will comply with the applicable standards and conditions for groundwater. <br /> Section 3.1.8 Wildlife: <br /> The mining and reclamation plans have been designed to account for the safety and <br /> protection of wildlife on the mine site. The Operator will mine the site in phases and use <br /> concurrent reclamation methods to minimize the impact on wildlife. The proposed <br /> reclamation plan may improve wildlife habitat. The proposed seed mix and plantings will <br /> create improved cover, foraging, and roosting areas for wildlife. The water area within the <br /> reservoirs will serve as habitat for waterfowl and other bird species and the fringes of the <br /> Martin Marietta Materials—Thunderbird Sand and Gravel—MLRB 112 Permit Application <br /> Exhibit E-3 <br />
