ATTACHMENT 3. <br /> EXHIBIT D. RECLAMATION PLAN <br /> Original Plan in standard case with additions (including clarification and explanation) underlined and <br /> deletions struck though: Numbering standardized. Minor spelling errors not called out. <br /> 1) After mining,the flattened area (final pit floor) will be graveled and used as a commercial site <br /> for my site and equipment storage. (And storage of materials used in his business, including <br /> scrap materials such as metal,tires,timber, concrete and asphalt rubble, earth and soil.) <br /> 2) The side slopes will be graded and seeded with range grasses and native trees, to achieve a <br /> natural appearance and provide wildlife habitat. The side slopes may also include variations in <br /> slope, including bench areas,to further improve the appearance of the site, and to take <br /> advantage of existing obiects (boulders, ledges) found during mining. <br /> 3) Side slopes are to be 1H:1V, to maximize the available space for the flattened area, while <br /> providing adequate safty and geotechnical stability (see Geotechnical Stability Exhibit). The <br /> slope will be offset from 10 to 20 feet from the permit boundary, as shown in maps. <br /> 4) As shown in Attachment 1 to Exhibit B, overburden and lenses of clay not suitable for <br /> construction materials, as well as additional soil and clean construction/demolition debris <br /> (concrete, rock, earth) brought from off-site, will be used for engineered backfill of highwalls. <br /> 5) Slopes will be completed within 12-18 months of the completion of mining in the lots which <br /> contain those slopes, including access roads at the top of the slope (for inspection and <br /> maintenance, necessary drainage features, and related work. <br /> 6) The "flattened area" in the floor of the pit will be reclaimed to provide development area for <br /> permanent commerical/light industrial use by the landowner. Reclamation includes final <br /> grading and compaction of the subgrade but does not include placement of the base course or <br /> metalling of the surface. Six (6) acres of the floor, including areas outside the permit boundary, <br /> will have a final grade of approximately 2% sloping down to the west, with a drainage swale <br /> around the north, east, and south perimeter, for stormwater management, erosion, and <br /> sediment control, in accordance with surface water/stormwater management plans (SWMP). <br /> 7) Sideslopes shall consist of the original highwalls, backfilled and buttressed with select, <br /> compacted, engineered fill using overburden (including clay lenses and subsoil from site and <br /> materials from off-site including concrete and asphalt construction debris and earth) to a 1:1 <br /> slope,followed by placement of soil (minimum 3 inches) with geofabric as necessary, seeding, <br /> and hydromulching. (See discussion in Geotechnical Stability Exhibit.) <br /> 8) Seeding will use one of the NRCS-recommended seed mixes with annual rye as a nurse crop. <br /> Native trees and shrubs from the immediate vicinity will be transplanted to the slope,to <br /> provide opportunity for self-seeding and browse for wildlife, although portions of the slope <br /> and its toe and head may be fenced off to reduce wildlife use until the vegetation is <br /> established. Irrigation is not proposed. <br /> Enclosures (All new to this revision): <br /> 1. NRCS seeding recommendations. <br /> 2. Seeding planting and weed control plan. <br /> 3.
