A. Plans for topsoil segregation, preservation and replacement; for <br />stabilization, compaction and grading of spoil; and for revegetation. <br />Topsoil shall be removed and segregated from other spoil. Please refer to the <br />Mining Plan Map in Exhibit C for general locations of stockpiles. For <br />reclamation, topsoil will be replaced by a scraper and generally graded with a <br />blade. Grading shall be done in a manner that controls erosion and siltation of <br />the affected land to protect areas outside the affected land from slides and <br />other damage. In addition, backfilling and grading shall be completed as soon <br />as feasible after the mining process. <br />Final grading will create a final topography that is appropriate for the final land <br />use. For example, final grading of the reservoir will replace material at a <br />maximum 3:1 slope to meet the grade at the top of the banks. Topsoil will be <br />uniformly placed and spread on areas disturbed by the mining, above the <br />anticipated high water line. The minimum thickness shall be 6 inches above <br />the surrounding finished grade, consistent with existing topsoil depths on-site. <br />The topsoil shah be keyed to the underlying and surrounding material by the <br />use of harrows, rollers or other equipment suitable for the purpose. <br />In those areas where revegetation is part of the reclamation plan, the Operator <br />will revegetate the land in such a manner so as to establish a diverse, <br />effective, and long-lasting vegetative cover that is capable of self•regeneration <br />without continued dependence on irrigation or fertilizer and is at least equal in <br />extent of cover to the natural vegetation of the surrounding area. Seed will be <br />drilled and mulched. <br />The revegetation seeding and plant list on the Reclamation Plan Map contains <br />the preferred species of grasses, shrubs and trees to be planted. <br />Seeding will take place once final grading and replacement of topsoil have <br />been completed for each phase. Timing of seeding will be consistent with <br />standard horticultural practice for dryland applications -generally between late <br />September and the middle of April to ensure there is adequate moisture for <br />germination. <br />During the reclamation of Phase 1 and 2 (Parker Property), existing perimeter <br />fences will be restored to present pre-mining condition. The fence will be <br />consistent with existing construction: 32"high, 3 strand 12 Yz gage - 4" <br />spacing barbed wire, with a maximum of 10' between posts. <br />Hall-Irwin Corporation -Parker/Dersham Sand and Gravel Mine - MLRB 112 Permit Application <br />Exhibit E - 4 <br />
