,S <br />,~~ <br />r <br /> <br /> <br /> <br />Reclamation Schedule <br />Alternative Reclamation Plan <br />SHB AGRA Project E92-7075 <br />Page 8 <br />Reclamation will occur concurrently with mining (except for the first three years of pit <br />excavation, during which period the stored waste will be revegetated until it is again moved as <br />pit backfill). Mining will proceed, generally, from south to north. Where possible, topsoil will <br />be immediately hauled directly to graded sites and placed prior to revegetation. For the first <br />three years, topsoil will need to be stored in the areas indicated on Exhibit E. <br />~' Reclamation Procedures <br />' Regrading <br />Through the course of mining, stored wasterock from the first three years' mining area will be <br />used in the backfill of the advancing pit. The regraded surface can be replaced within <br />approximately six feet of the original surface elevation, except in the northeast corner where a <br />depression will accompany the development of approximately 20 acres of wetland. A visual <br />screen approximately six feet in height will be constructed along the relocated county road. This <br />screen will have sideslopes no steeper than 4(h):1(v). <br />' In the regraded areas where wasterock was used as fill, fine overburden will be placed to depths <br />from 2 to 5 feet prior to topsoil placement to provide subsoil for revegetation. <br />' Topsoil Salvage <br />Topsoil will be salvaged to a depth of 12 inches. Soil will be transported to the storage pile <br />' indicated on Map E, or placed directly on a graded surface in preparation for seeding/planting. <br />' Topsoil Storage <br />Topsoil will be stored in piles with slopes no steeper than 4(h):1(v). An interceptor berm will <br />' be constructed around each pile. The stored material will be stabilized as indicated under <br />Temporary Surface Stabilization, below. <br />' Topsoil Placement <br />Topsoil will be replaced on graded slopes at depths of 4 to 8 inches. Prior to placement, the <br />graded slopes will be left rough to facilitate adhesion of the topsoil layer. Topsoil depth will <br />be monitored during placement by reclamation personnel to verify that it is within the specified <br />range of depths. <br />AGRA <br />' Eerth &Enviionmentel Group <br />
