normally be reapplied by hauling, in trucks, from topsoil stockpiles or from areas where <br />topsoil has been removed for mining advance, to the regraded spoil areas and then <br />redistributed with dozers. Alternate methods may also include placing topsoil on slopes with <br />a dragline followed by redistribution with dozer, or using a scraper to redistribute the topsoil. <br />When necessary to ensure replacement to the required depths, replacement depths will be <br />staked on the regraded spoil <br />Reapplied topsoil will be left in a rough condition to control wind and water erosion prior to <br />seeding. Seedbed preparation, other surface manipulation practices and seeding will be <br />completed primarily during the fall months.. Contour furrows, approximately 4-6 inches deep <br />at the deepest point and 20-25 inches wide, which have been used on slope areas very <br />successfully during the past 13 years, will be used to reduce erosion potential, conserve <br />moisture, and maintain site stability until vegetation is sufficiently established. The size of <br />the furrows may be increased if necessary to control erosion, and the distance between the <br />furrows will vary, but will be approximately 10 to 20 feet along the slope. Small rock check <br />dams may also be used where appropriate to aid in control of erosion both prior to seeding <br />and ifnecessary, after an area has been seeded. <br />Revegetation Plan <br />Following the retopsoiling of an area, any necessary fertilization, chiseling, construction of <br />contour furrows, and seeding of the reclamation will take place. <br />• The approved reclamation seed mixture, as shown in Table 7, Reclamation Seed Mixture, <br />contains sufficient diversity for ecological stability. The seed mixture contains a variety of <br />grasses, forbs and shrub species well adapted to the soil and moisture conditions found at <br />Colowyo. The diverse seed mixture is capable of self selection for each reclaimed micro- <br />habitat encountered in the reclaimed areas. The diverse seed mixture is required to ensure <br />quick erosion control for the first few years of reclamation as well as obtaining the desired <br />post-mining vegetative community with the same seasonal variety and lifeform of the <br />premined area. <br /> <br />2.05-42 Revision Date: 6/i 8/02 <br />Revision No.: MR-57 <br />
