occur as mining approaches the toe of the interior slopes and will not be steeper than <br />3H:1V. Since the pit floors will be underwater, no grading or topsoil replacement will <br />occur. They operator may find it useful to dispose of some pit-run waste material to a <br />minimal extent. Such material will be non-toxic and non-hazardous when placed below <br />the expected pit water level. <br />Other topsoil replacement will be accomplished after mining has moved far enough away <br />from an active mining or construction area to protect the topsoil and make it practical for <br />seed bed preparation and seeding. Final seeding and seedbed preparation wiIl also be <br />governed by the time of year and weather conditions that are optimal for these activities. <br />(5) All refuse and acid-forming or toxic producing materials that have been mined shall <br />be handled and disposed of in a manner that will control unsightliness and protect <br />the drainage system from pollution: No refuse or toxic or hazardous material is <br />expected to be generated by this mining operation. Waste material may be produced as <br />part of the concrete and/or asphalt batch plants. Where such material is produced, it will <br />be handled in such a manner that conforms to local, State and Federal requirements for <br />disposal of such material. At present time the Operator does not intend to dispose of such <br />materials on the mine site. <br />(6) Any drill or auger holes that are part of the mining operation shall be plugged in <br />accordance with methods approved by the Division: No adits or shafts will be <br />employed in this operation. All drilled or auger holes will occur within the limits of the <br />slurry wall or area excavated by the mining operation, therefore ground water resources <br />will not be impacted. However, if any drill, backhoe pits or auger holes are required <br />outside the confines of the slurry wall, they will be constructed by trained crews and shall <br />be backfilled as soon as practicable. <br />(7) Maximum slopes and slope combination shall be compatible with the configuration <br />of the surrounding conditions and the selected post mining land use: The proposed <br />post mining land use will be developed water resource. The final interior pit slopes will <br />not be steeper than 3H:1 V. The constructed dams that will surround the excavated areas <br />will be according to site specific designs for earthen dams approved by the approving <br />authority. <br />(8) Not applicable <br />(9) Placement of inert structural fill imported from off-site: At this time the Operator <br />does not intend to import inert structural fill imported from off-site. If such material is <br />imported, the Operator will comply with the provision of Section 3.1.5{9) of the <br />Division's and Mined Land Reclamation Board's regulation. <br />
