The only <br />exception would be if any of the remaining ponds are identified as <br />beneficial relative to use as livestock or wildlife water sources <br />consistent with applicable provisions of Rule 4.05.9(13), and approved <br />for retention by the DMG. <br />Pond reclamation will typically involve removal and disposal of <br />discharge structures, grading of any embankment fill material into the <br />pond basin, and grading of the pond disturbance area to blend with the <br />surrounding terrain. Soil required for reclamation of sedimentation <br />pond sites has been stored in soil stockpiles adjacent to pond areas <br />as shown on Map 31a, Kerr Mine Area Soil Removal and Storage, until <br />such time as sedimentation pond reclamation occurs. The methods to be <br />implemented to prevent deterioration of soil during storage are fully <br />described under Section 780.18 and Sections 616.21 through 816.25 of <br />this application. Upon removal of each sedimentation pond, the <br />affected land will be regraded and revegetated in accordance with <br />• Sections 816.100-816.106 and 816.111-81 6.117. <br />Ponds A, B, D, and E are existing sedimentation ponds. They contain <br />water throughout all or most of the year and typically have some <br />established riparian vegetation. Kerr proposes to retain Ponds A, B, <br />D, and E as permanent impoundments. These ponds would be used as <br />stock ponds for livestock grazing and would continue to be used as <br />small impoundments for wildlife use and habitat as they have been <br />since 1979. Both livestock grazing and wildlife habitat are <br />components of the proposed and approved postmining land use. <br />Pond P. was created by constructing an embankment across an existing <br />natural drainage tc impound intermittent flows and disturbed area <br />runoff from the southern portion of the current permit area and <br />adjacent areas. <br />Fond B was created by excavating a depression in an existing ephemeral <br />drainage channel and constructing a low embankment of sufficient .size <br />• to retain the required volume of runoff from a portion of the <br />disturbed area. Originally this pond did not retain water year-round, <br />~~`~~ 780-1U Revised April 2009 <br />M 2-3q <br />
