• include keeping ditches, culverts, spillways, and other outflow <br />structures free of debris. All combustible material, other than mulch <br />or other material needed for erosion control and surface stability, will <br />be removed. <br />Plans for any modification o~ the sedimentation impoundment or dam will <br />be submitted to the Colorado Mined Land Reclamation Division, and no <br />modification will begin until the approval of the plans has been granted <br />unless such modification is necessary upon an emergency basis for public <br />health or safety, or if the environment is endangered. <br />4.05.10 Underground Mine Entry and Access Discharges <br />No gravity discharge of water from the mining operation is anticipated <br />to occur. Sunbelt currently does not discharge water from the Peacock <br />Coal Mine. In addition, no water has ever been discharged from the <br />abandoned workings of the Peacock Coal Mine. <br />• If groundwater is encountered, it will be routed to an underground sump, <br />where it will be used for dust control in the underground mining. <br />4.05.11 Groundwater Protection <br />As noted earlier in Section 2.04.7, there is no presence of any <br />groundwater in or above the area to be mined by the underground <br />operations. Likewise, no acid-forming or toxic-forming materials have <br />been found to exist. <br />4.05.12 Protection of Groundwater Recharge Capacity <br />The reclamation plan, as described in Section 2.05.4, will return the <br />disturbed land to approximately the pre-mining condition; therefore, <br />groundwater recharge capability is expected to remain essentially the <br />same as the pre-mining condition. Also, because of the lack of <br />• groundwater in the permit area, the mining operation and subsequent <br />reclamation and sealing of the portals should have no adverse affect on <br />the existing groundwater recharge capabilities. <br />4.05-7 <br />
