replaced by a scraper, haul truck, or other suitable means, and generally graded with a <br /> blade. Grading shall be done in a manner that controls erosion and siltation of the affected <br /> land and protects areas outside the affected land from siltation and other damage. In <br /> addition, backfilling and grading shall be completed as soon as feasible after the mining <br /> process. <br /> Final grading will create a final topography that is appropriate for the final land use. For <br /> example, final grading of the reservoir below and above the high-water line will create <br /> slopes no steeper than 3:1 (horizontal to vertical) below the top of the banks. Topsoil will <br /> be placed and spread on areas disturbed by the mining, above the anticipated high-water <br /> line. The minimum top soil thickness shall be 6 inches. The topsoil shall be keyed to the <br /> underlying and surrounding material by the use of harrows, rollers or other equipment <br /> suitable for the purpose. <br /> In those areas where revegetation is part of the reclamation plan, the Operator will <br /> revegetate the land in such a manner as to establish a diverse, effective, and long-lasting <br /> vegetative cover that is capable of self-regeneration without continued dependence on <br /> irrigation or fertilizer and is at least equal in extent of cover to the natural vegetation of the <br /> surrounding area. Seed will be drilled and mulched. <br /> The revegetation seeding and plant list on the Reclamation Plan Map contains the <br /> preferred species of grasses, shrubs and trees to be planted. <br /> Seeding will take place once final grading and replacement of topsoil have been completed <br /> for each phase. Timing of seeding will be consistent with standard horticultural practice for <br /> dryland applications- generally between late September and the middle of April to ensure <br /> there is adequate moisture for germination. <br /> (e) A plan or schedule indicating how and when reclamation will be implemented. <br /> Include: <br /> i. An estimate of the periods of time which will be required for the various stages or <br /> phases of reclamation. <br /> Reclamation for any given stage of mining may take up to five years to allow for successful <br /> revegetation. Please refer to the Timetable for Mining and Reclamation in Section (e) of <br /> Exhibit D. <br /> ii. A description of the size and location of each area to be reclaimed during each <br /> phase. <br /> Please refer to the Reclamation Plan Map (Exhibit F). <br /> iii. Outlining the sequence in which each stage or phase of reclamation will be carried <br /> out. <br /> Please refer to the Timetable for Mining and Reclamation in Section (e) of Exhibit D. <br /> (fJ A description of: <br /> Martin Marietta Materials—Thunderbird Sand and Gravel—MLRB 112 Permit Application <br /> Exhibit E-5 <br />
