1 <br />Banks and Gessa, LLC <br />approxi~~~ately 740,000 cubic yards of topseil and overburden d!~ring the mining <br />' process. in addition, approximately 470,000 cubic yards of clay material within <br />' the alluvium will be salvaged frcrn the new mining areas. Approximately 640,000 <br />cubic yards of backfill will be required to slope the near-vertically mined pit walls. <br />' The topsoil requirement as plant-growth medium for the disturbed surface <br />' acreage will be approximately 110,000 cubic yards to cover the perimeter of the <br />reservoir and other disturbed areas at 12 inches deep. The amount of topsoil <br />required for surface reclamation as plant-growth medium is minimal compared to <br />' the amount that is available. <br />' Topsoil Preservation <br />The location of the topsoil stockpiles will be within the permit area and located <br />along the western property boundaries. Typical topsoil berm locations can be <br />seen on Exhibit C-3. These locations will minimize impacts to the floodplain, as <br />well as reduce noise and visual impacts to the neighbors. <br />Topsoil stockpiled in berms for later use in revegetation will be placed on a stable <br />surface within the permit area and will be clearly marked. These topsoil <br />stockpiles will be protected with temporary revegetation from disturbances <br />associated with the mining operation and from wind and water erosion, <br />compaction and other disturbances that would reduce its capability to support <br />permanent reclamation vegetafio~ ~.
