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