General Overview of the Reclamation Plan <br /> Reclamation of the proposed permit area will include backfilling, compacting, grading, and <br /> stabilization of areas to be further developed following release from the MLRB reclamation <br /> permit. Backfilling has been, and will continue to be, completed with appropriate common fill <br /> materials with compaction that accommodates development of future structures. Grading of <br /> backfilled areas will occur in anticipation of future street, utility, and stormwater sewer design <br /> and construction. Surface areas disturbed by mining activities will be stabilized with erosion <br /> resistant materials. If the area is planned for development shortly after MLRB reclamation permit <br /> release, temporary stabilizers such as soil tackifier or rock may be used. If development is not <br /> planned until after at least one growing season, the area may be surfaced with topsoil and <br /> revegetated with a fast-growing cover-crop grass mixture during reclamation. If used, the <br /> revegetation will generate a blend of fast growing, stabilizing, grass species and, given suitable <br /> precipitation, should produce good grass cover to minimize erosion and excessive weed growth. <br /> In general, level and shallower reclaimed slopes will provide easier and safer access during <br /> reclamation and be more compatibility with future development plans. Shallower slopes will <br /> also aid in stabilizing soils, establishing vegetation growth, and minimizing erosion. Although <br /> slopes created by mining activities will be backfilled and graded to create topography necessary <br /> for future development, no slopes will be reclaimed any steeper than 3H:1 V. <br /> Reclamation Measures/Materials Handling <br /> Available topsoil, overburden, and clay materials have been stockpiled or previously used for <br /> reclamation. Similar to mining, earth moving equipment may include, but is not limited to <br /> dozers, loaders, scrapers, and excavators. Farm equipment for grading and seeding may be used <br /> for revegetation activities. <br /> Materials Handling - Backfilling <br /> The below-grade reservoir location is the only area of the existing mine pit site that will not be <br /> backfilled. Side slopes of the reservoir shall be formed by placing and compacting appropriate <br /> backfill material to create the reservoir clay liner. However, the interior of the reservoir shall <br /> remain excavated to bedrock. Final reservoir side slopes may be as steep as 3H:1 V. <br /> Most areas of the site being backfilled will be used for future building and associated <br /> infrastructure development. Therefore, material used for backfill in these areas is sorted, placed, <br /> and compacted according to meet future development requirements. These mined areas remain <br /> dewatered until the desired backfilling and grading is complete. Since backfilling of the mining <br /> areas and other reclamation activities have been, and shall continue be, concurrent with mining, <br /> topsoil, overburden, and non-marketable material excavated during mining is used almost <br /> immediately. The only exception has been the existing landscape/floodway diversion berms <br /> created on the south side of the site during initial mining activities. <br /> Scrapers or haul trucks used during mining are also used to transport acceptable backfill material <br /> from the source location to the mining area ready for backfilling. Small temporary stockpiles <br /> may be created within or along the edge of the mining area and, when sufficient material is <br /> Timnath Connell Ptt <br /> DRMS 112 Permit Amendment Application Page 11 <br />
