GENERAL GUIDELINE FOR RECLAMATION FROM THE LOCAL NRCS <br />OFFICE <br />1.) Topsoil should be removed and stockpiled during mining. When <br />mining is completed, the topsoil should be placed, in areas in <br />need of reclamation (such as road banks and side slopes), so <br />that at least six inches of topsoil material is covering the subsoil <br />material. Topsoil amounts exceeding six inches in depth will <br />result in increased seeding success. <br />If the topsoil will not be used within one year, then it should be <br />seeded with the seed mixture listed in step #5 to protect it from <br />erosion and keep it biologically active. <br />2.) Prior to revegetation, the area should be banksloped so that no <br />slope exceeds a 3:1 slope. Slopes greater than 3:1 will need to <br />have a rolled erosion control product (RECP) applied after <br />seeding to reduce erosion and increase seeding success. Roads <br />and other similarly disturbed areas should be graded or <br />reworked so as to blend into or approximate the surrounding <br />landscape as closely as possible. Rough areas should be <br />smoothed to permit easier seeding and mulching. At least <br />eighteen inches of subsoil material should remain on -site prior to <br />spreading the topsoil. The subsoil material should not be over - <br />compacted. Plant roots will not be able to grow in heavily <br />compacted subsoils. Also, compaction reduces the amount of <br />water available to the plant. Additional soil material, topsoil or <br />subsoil, will increase the success of the seeding. When <br />banksloping and shaping of the subsoil is complete, scarify the <br />area to a depth of six inches to permit better bonding between <br />the subsoil and the topsoil. After scarification, the topsoil should <br />be uniformly spread over the area. <br />3.) The seedbed should be well settled and firm, but friable enough <br />so that seed can be placed at the recommended seeding depth. <br />The ideal firmness is when a one -half inch boot print remains <br />after walking across the soil surface. <br />If the topsoil is over - compacted by traffic or equipment, three <br />steps are required to prepare the seedbed. First, the soil should <br />be tilled to break up root restricting layers. Second, it should be <br />harrowed. Third, the soil should be rolled or packed. These <br />steps establish the necessary firm seedbed. <br />
