Topsoil and Overburden <br />Topsoil will be segregated from subsoil and other materials during clearing of the mine <br />site. The topsoil will be stockpiled just outside of current mining operations and will be <br />replaced to a depth of 6" to 12" upon backfilled or unexcavated subsoil in a sloped <br />farmland or shoreline configuration. This replacement will be a continuing process <br />following the mining operation. The placement of topsoil and backfill of sloped areas and <br />shoreline will continue throughout each phase of mining to the greatest extent possible. <br />Stabilization and compaction of backfill materials will be accomplished by loading and/or <br />dozing of subsoil or waste materials first into the wet or dry mined area. The backfill will <br />then be loaded with the earth work equipment as backfilling continues, raising the backfill <br />farmland and shoreline elevations to final grade. Any areas of the shoreline showing <br />signs of instability, consolidation, or collapse will continue to be worked until compaction <br />and slope gradients achieve a stable configuration. <br />Grass Seedlna <br />The following grass seed mix will be used in reclamation for the areas between and <br />surrounding the shorelines. <br />Buffalograss <br />Blue grama grass <br />Alkali sacaton <br />Little bluestem <br />Sandberg bluegrass <br />Cicer milkvetch <br />Totsls <br />*Rate - <br />Ibs.
