pits, a portion of the reclaimed area will be fields for recreation made with artificial turf. For <br /> industrial/commercial areas within the soil storage area, the ground will be covered with a six- <br /> inch thick gravel layer screened from material onsite. Topsoil will be stored into the temporary <br /> stockpile area as shown on Map C-2 for rangeland reclamation. <br /> 6.1. Topsoil and Overburden Handling <br /> It is not anticipated that any topsoil will need to be imported for the reclamation process, even at <br /> the point of greatest disturbance. The soil profile is such that sufficient topsoil will always be <br /> available to topsoil all required areas to rangeland. Topsoil stripped during mining and not <br /> required for reclamation will either be sold or stored in the temporary stockpile area. Topsoil and <br /> overburden will be maintained in separate stockpiles in the temporary stockpile area. Table E-2 <br /> outlines the topsoil material balance calculations during reclamation and during the greatest <br /> disturbance area scenario. Topsoil stripping and replacement volumes are based on a 12 <br /> inches depth of topsoil. Table E-2 details the volumes produced form the Soil Storage Area and <br /> Pits 1-4. <br /> Table E-2.
