• • <br /> with no difficulty after the reclamation has been completed. The creation of the lakes will create <br /> more opportunities for aquatic birds, mammals, and fish. <br /> Topsoiling <br /> The top six inches of soil is classified as topsoil. This laver includes the root zone of the grasses. <br /> It will be stripped and stockpiled separately. By using concurrent reclamation techniques, the <br /> topsoil in the stockpile should only remain for one to two years. If the stockpile remains more <br /> then one growing season, it will be seeded with Wheatgrass to prevent erosion. <br /> Topsoil will be replaced in reclaimed areas in the same six inch depth. <br /> Revegetation <br /> The purpose of revegetation is to re-establish the pasture grasses for cattle and horses in Phases 2 <br /> and 3. Slopes will be no greater than 3:1. The grasses were selected to be long lasting and <br /> regenerate themselves. The ground will be fine graded and prepared for seeding. Fertilizers will <br /> be used according to reconunendations from the Soil Conservation Services. The operator will <br /> contact the Soil Conservation Service periodically throughout reclamation for soil tests. <br /> In Phase 1, the 8:1 slopes on the east and west sides of the lake are to be planted with wetland <br /> vegetation as specified in the Corps permit. Other areas surrounding the lake will be planted <br /> with the grasses recommended within this permit. <br /> If a significant invasion of noxious weeds occurs,the area will be mowed periodically for <br /> control. Weeds will be mowed before they go to seed during the first growing season. <br /> Mechanical control will be used as a first priority. Chemical methods will only be used if no <br /> other alternative produces acceptable results. <br /> As mining operations are completed, the area will be graded and shaped. Runoff or excess water <br /> from adjacent areas will not be allowed to flow over any of the slopes. Berms will be <br /> constructed to divert this excess water and dispose of it in a safe and non-erosive manner. <br /> The seedbed will be worked up and be weed free and firm at the time of planting. 1f the seed is <br /> broadcast. the seeding rates will be doubled. <br /> Based on the soils in the area, the following seeding mixtures are recommended: <br /> Vaughn Side Oats Grama 30% 1.35 #PLS/ac. <br /> Grenville Switchgrass 20% 0.5 #PLS/ac. <br /> Lovington Blue Grama 20% 0.3 #PLS/ac. <br /> Barton Western Wheatgrass 30% 2.4 #PLS/ac. <br /> - OR - <br /> Barton Western Wheatgrass 30% 3.2 #PLS/ac. <br /> Luna Pubescent Wheatgrass 30% 3.6 #PLS/ac. <br /> Lincoln Smooth Bromegrass 40% 1.30 #PLS/ac. <br /> E-3 <br />
