<br />Hall-Irwin will protect the existing and "reasonably potential" future uses of groundwater. <br />`y, We are in process of applying for a well permit and required temporary substitute supply <br />plan to augment evaporative loss from the ponds. We will forward copies of the appropriatt <br />documents once the State Engineer has completed review of the applications. <br />All aspects of the mining and reclamation plans shall take into account the safety and ~ <br />protection of wildlife on the mine site, at processing sites, and along all access roads to the <br />mine site with special attention given to critical periods in the life cycle of those species <br />which require special consideration. <br />Topsoil shall be removed and segregated from other spoil. Topsoil stockpiles shall be <br />stored in places and configurations to minimize erosion and located in areas where <br />disturbance by ongoing mining operations will be minimized. Once stockpiled, topsoil shall <br />be rehandled as little as possible. <br />[n those areas where revegetation is part of the reclamation plan, land shall be revegetated <br />in a way as to establish a diverse, effective, and long-lasting vegetative cover that is capable <br />ofself-regeneration without continued dependence on irrigation or fertilizer and is at least <br />equal in extent of cover to the natural vegetation of the surrounding area. <br />Hall-Irvin will post appropriate signage at the entrance to the mine site. <br />D. Plans for topsoil segregation, preservation and replacement; for stabilization, compaction, <br />and grading of spoil; and for revegetation. <br />Topsoil shall be removed and segregated from other spoil. Please refer to the Mining Plan Map <br />for specific location of stockpiles. For reclamation, topsoil will be replaced by a scraper and <br />generally graded with a blade. All grading shall be done in a manner that controls erosion and <br />siitation of the affected land to protect areas outside the affected land from slides and other <br />damage. In addition, all backfilling and grading shall be completed as soon as feasible after the <br />mining process. <br />Final grading will create a final topography that is appropriate for the final land use. For <br />example, final grading will replace topsoil at a maximum 4:l slope to meet the grade at the top <br />of the banks. Topsoil will be replaced on all slopes above the high water line. Bare mineral <br />soil along the shoreline wetland bench (below the high water line) will be scarified in mid-May <br />to late June to allow for Cottonwood and other wetland vegetation establishment. <br />Topsoil will be uniformly placed and spread on all areas disturbed by the mining, above the <br />anticipated high water line. The minimum thickness shall be to 12 inches above the <br />surrounding Yinished grade. 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 revegetate the <br />land in such a way as to establish a diverse, effective, and long-lasting vegetative cover that is <br />capable ofself-regeneration without continued dependence on irrigation or fertilizer and is at <br />least equal in extent of cover to the natural vegetation of the surrounding area. Seed will be <br />drilled and mulched. <br />Hal!-Irwin Mixing Proposal jor the Shores - MLRB I I2 Permit 21 <br />
