Topsoiling <br /> The top 2 to 6 inches of soil on the property is classified as topsoil. This layer includes the root <br /> zone of grasses and crops, which will be stripped and stockpiled separately. By using concurrent <br /> reclamation techniques, the topsoil is not expected to remain in stockpiles for more than I to 2 <br /> years. If the stockpile remains more than one growing season, it will be seeded with a fast <br /> growing vegetative cover to prevent erosion. All topsoil will be retained on-site to reclaim the <br /> lake shoreline, replacement wetlands, and other areas disturbed by mining activities. Where <br /> required, topsoil will be replaced to a depth of approximately 4 to 6 inches. <br /> When necessary, stripped topsoil will be stockpiled parallel to potential flood flows to reduce the <br /> risk of inhibiting the flow. Throughout the mining phases, the amount of topsoil stockpiled will <br /> be limited by continuously using it to cap backfilled areas. <br /> Revegetation <br /> As mining operations are completed, areas for reclamation will be graded and shaped for <br /> revegetation. Runoff or excess water from adjacent areas will not be allowed to flow over slopes <br /> being graded and seeded. If needed, berms will be constructed to divert excess water and dispose <br /> of it in a safe and non-erosive manner. <br /> Upland Areas. The grass mixture below was selected to be long lasting and regenerating. The <br /> ground will be fine graded prior to seeding and fertilizers will be applied according to <br /> recommendations from the Natural Resource Conservation Service. Lake side slopes below the <br /> anticipated water level will not be seeded. Based on the soils in the area, the following upland <br /> seed mixture is recommended: <br /> Application Rate Area Cover <br /> Upland Grass Seed #PLS/acre <br /> Western Wheat grass 3.75 25 % <br /> Timothy 3.75 25 % <br /> Slender Wheat grass 1.5 10 % <br /> Smooth Brome rass 1.5 10 % <br /> Kentucky Bluegrass 1.5 10 % <br /> Redtop 0.75 5 % <br /> Meadow Foxtail 0.75 5 % <br /> Spreading Bent grass 0.75 5 % <br /> Reed Canarygrass 0.75 5 % <br /> Application rate is for drilling the seed. <br /> If seed is to be broadcast, the application rate will be doubled. <br /> Upland grass seed will be planted with a drill equipped with depth bands and press wheels. The <br /> seeded areas will then be covered with straw mulch at a rate of 2,000 pounds per acre. The straw <br /> will be crimped into the soil to control erosion until the grass becomes established. <br /> River Valley Resource <br /> DUG ll:Permit <br /> Page 9 <br />
