Revised, September 12, 1995 <br />normally be reapplied by hauling, in trucks, from topsoil <br />stockpiles or from areas where topsoil has been removed for mining <br />advance, to the regraded spoil areas and then redistributed with <br />dozers. Alternate methods may also include placing topsoil on <br />slopes with a dragline followed by redistribution with dozer, or <br />using a scraper to redistribute the topsoil. When necessary to <br />ensure replacement to the required depths, replacement depths will <br />be staked on the regraded spoil. <br />Reapplied topsoil will be left in a rough condition to control wind <br />and water erosion prior to seeding. Seedbed preparation, other <br />surface manipulation practices and seeding will be completed <br />primarily during the fall months. Contour furrows, approximately <br />4-6 inches deep at the deepest point and 20-25 inches wide, which <br />have been used on slope areas very successfully during the past 13 <br />years, will be used to reduce erosion potential, conserve moisture, <br />and maintain site stability until vegetation is sufficiently <br />established. The size of the furrows may be increased if necessary <br />to control erosion, and the distance between the furrows will vary, <br />but will be approximately 10 to 20 feet along the slope. Small <br />rock check dams may also be used where appropriate to aid in <br />control of erosion both prior to seeding and if necessary, after an <br />area has been seeded. <br />ReveQetation Plan <br />Following the retopsoiling of an area, any necessary fertilization, <br />chiseling, construction of contour furrows and seeding of the <br />reclamation will take place. <br />The approved reclamation seed mixture, as shown in Table 7, <br />Reclamation Seed Mixture, contains sufficient diversity for <br />ecological stability. The seed mixture contains a variety of <br />grasses, forbs and shrub species well adapted to the soil and <br />moisture conditions found at Colowyo. The diverse seed mixture is <br />capable of self selection for each reclaimed micro-habitat <br />encountered in the reclaimed areas. The diverse seed mixture is <br />required to ensure quick erosion control for the first few years of <br />reclamation as well as obtaining the desired post-mining vegetative <br />community with the same seasonal variety and lifeform of the pre- <br />mined area. <br />.~ <br />2.05-42 <br />
