D. Plans for topsoil segregation, preservation and replacement; for stabilization, <br />compaction, and grading of spoil; and for revegetation. <br />Topsoil shall be removed and segregated from other spoil. Please refer to the Mining <br />Plan Map in Exhibit C for specific location of stockpiles. For rec]amation, topsoil will be <br />replaced by a scraper and generally graded with a blade. All grading shall be done in a <br />manner that controls erosion and siltation of the affected land to protect areas outside the <br />affected land from slides and other damage. In addition, all backfilling and grading shall <br />be completed as soon as feasible after the mining process. <br />Final grading will create a final topography that is appropriate for the final land use. For <br />example, final grading of the ponds will replace material at a maximum 3:1 slope to meet <br />the grade at the top of the banks. Topsoil will be replaced on the slopes above the high <br />water line. Topsoil will be uniformly placed and spread on all areas disturbed by the <br />mining, above the anticipated high water line. The minimum thickness shall be to 6 <br />inches above the surrounding finished grade, consistent with the depth of topsoil at the <br />site prior to mining. The topsoil shall be keyed to the underlying and surrounding <br />material by the use of harrows, rollers or other equipment suitable for the purpose. <br />In those areas where revegetation is part of the reclamation plan, Hall-Irwin will <br />revegetate the land in such a manner so as to establish a diverse, effective, and long- <br />lasting vegetative cover that is capable of self-regeneration without continued <br />dependence on imgation or fertilizer and is at least equal in extent of cover to the natural <br />vegetation of the surrounding area. Seed will be drilled and mulched. <br />The revegetation seeding and plant list on the Reclamation Plan Map contains the <br />prefen•ed species of grass, legumes, forbs and shrubs to be planted, the hydraulic regime <br />and the approximate height of the plantings. <br />Seeding will take place once final grading and replacement of topsoil has been completed <br />for each phase. Timing of seeding will be consistent with standard horticultural practice <br />for dryland applications -generally between late September and the middle of April to <br />assure adequate moisture for germination. Additional plantings will be installed once the <br />ponds have filled with water and will be watered by hand for the first two growing <br />seasons. Long-term maintenance of the shoreline vegetation will be the responsibility of <br />the landowner. <br />E. A schedule indicating how and when reclamation will be implemented. The <br />schedule shall include: <br />1.
