RULE 4 PERFORMANCE STANDARDS <br />4.13 Contemporaneous Reclamation <br />All reclamation actives, including but not limited to backfilling, grading, topsoil, replacement and <br />revegetation, will be carried out as contemporaneously as practicable with mining operations. <br />Implementation of the reclamation plan, as described in Section 2.05.4, will assure that each step in the <br />reclamation process is completed in a timely manner. <br />Because of the multi-seam nature of the mining operation described in Section 2.05, backfilling and <br />grading cannot be completed within 180 days following the coal removal. Backflling and grading will be <br />completed in variance of the 180 day requirement in a manner previously approved and described below, <br />and in Sections 2.05 and 4.14.1. As shown on the mining Range Diagram (Map 24), mining will be <br />carried out in any one area for a considerable length of time. A series of benches will be necessary in the <br />operation to recover the lower coal seams, and an additional series of benches will be necessary to dump <br />the shovel/truck overburden material in a configuration that achieves the topography shown on the post- <br />mining Topography Map (Map 19). When multi-seams are mined, backfilling and rough grading cannot <br />begin until the lower-most seam is mined. See Spoil Grading Map (Map 29), which shows the time <br />frames in which grading will occur in relation to the time of removal of "X" seam coal, which is shown <br />on the Mine Plan Map (Map 23). <br />Topsoil will be removed prior to the mining disturbance according to the timetable established on the <br />Topsoil Handling - South Map (Map 28). As can be observed from this map, the initial topsoil removed <br />at the operation must be stockpiled; however, as the operation progresses, topsoil can. be immediately <br />redistributed rather than stockpiled. <br />Revegetation will commence as soon as the topsoil has been redistributed and prepared for seeding as <br />described in Section 2.05.4. The area will be seeded with the seed mixture described in Section 2.05.4 as <br />quickly as possible. <br />Rule 4 Performance Standards 4.13-1 Revision Date: 6/23/08 <br />Revision No.: MR-91
