<br />• Following the removal of the structures and the foundations, dozers or <br />graders will be used, where necessary, to reshape the area to produce a <br />surface similar to the pre-mining topography. Equipment will leave the <br />surface in a rough or furrowed condition along the contour. Smooth <br />compacted surfaces will be avoided to reduce the erosion and subsequent <br />sedimentation problems. <br />The final grading before topsoil placement will be done along the <br />contour by dozers and motor graders. The final surface grade will match <br />the overall approximate pre-mining grade. The proposed final surface <br />configuration is shown on the Post-14ining Topography Map (Map 12). <br />Topsoil Redistribution Plan <br />Prior to the reapplication of the topsoil, the area will be graded, <br />where necessary, along the contour to minimize erasion, assure stability <br />and minimize slippage. The topsoil will be applied in a uniform and <br />• stable thickness that is capable of supporting the post-mining land <br />uses. Following reapplication of the topsoil and the final grading of <br />that material, the topsoil will be scarified with a chisel plow to <br />alleviate compaction caused by machinery. This treatment will promote <br />root penetration of the planted vegetation. <br />Wind and water erosion will be controlled prior to seeding by leaving <br />the reapplied topsoil in a rough condition. Because of the sandy soils <br />found in this area, the area will be seeded after straw mulch has been <br />applied. If the seed is drilled first followed by the application and <br />crimping of the mulch, then the seed will be buried so deep that none of <br />the seed will be able to grow. Therefore, the entire retopsoiled area <br />will be mulched as soon as possible after it has been prepared for <br />seeding. Immediately following mulching and seeding, any slope areas <br />will be furrowed or treated with a tactifier or netting to reduce <br />erosion potential and maintain site stability until such time as the <br />. vegetation is sufficiently established. <br />REVISED <br />2.05-39 NOVEMBER 1983 <br />
