Black Obsidian Pit—Permit M-1987-026 <br /> 112c Conversion Application <br /> Rule 6.4.5 <br /> Exhibit E <br /> Reclamation Plan <br /> General—The site will be reclaimed as Rangeland, with slope gradients appropriate for livestock and <br /> wildlife, and revegetated to support this use. <br /> Reclamation in Phase I <br /> Reclamation will include concurrent reclamation wherever feasible; it will begin and proceed during <br /> Phase I mining operations, mainly involving the shaping of overburden disposal areas,followed by <br /> topsoil placement and revegetation. It will be carried out where there will be no further mining or other <br /> disturbance. <br /> Reclaimed surfaces will be 3H:1V or gentler, excluding quarry highwalls consisting of exposed obsidian. <br /> Overburden and Topsoil Handling, Revepetation <br /> Native topsoil is present throughout most of the undisturbed portions of the expanded permit area, <br /> though depths vary. All topsoil in disturbed areas will be stripped prior to disturbance, and will either be <br /> directly placed as a permanent surface layer to be revegetated during concurrent reclamation, or saved <br /> in temporary stockpiles for later use in final reclamation. (See Exhibit I for detailed soils information.) <br /> The places where the salvaged topsoil will be placed consist of the following areas: (a)as a cap on the <br /> permanent overburden disposal cells, (b) on the outslope of the expanded operations/staging and <br /> stockpile area, (c) on the surfaces of the sloped areas (such as the sloped overburden left in place above <br /> the expanded quarry highwall), (d) on finished quarry benches, or(e) placed in temporary stockpiles for <br /> later use in reclamation. <br /> There will be a surplus of topsoil at the conclusion of mining. Topsoil will be spread on reclaimed <br /> surfaces at a depth of 6 or more inches. All areas where topsoil is placed, including the topsoil <br /> stockpiles, will be seeded in a timely manner with the approved revegetation seed mix at the approved <br /> rates. <br /> Overburden is present throughout most of the permit area, and in some locations is many feet deep. <br /> After topsoil is stripped prior to disturbance, overburden will be moved to allow expansion of the mining <br /> to proceed. Initially, overburden will be used as fill to construct the expanded operations pad in the pit <br /> and for construction of the stormwater control berms. <br /> After all necessary overburden material is used for fill and shaping, the excess overburden will be hauled <br /> to permanent overburden disposal cells, where it will be shaped for stability and to blend with <br /> surrounding topography. All disposed overburden will be covered with topsoil and seeded. (Note:The <br /> overburden disposal cell will be set back from the powerline by 200 feet.) <br />
