Topsoiling <br />The top two to six inches of soil on the property is classified as topsoil. This layer includes the <br />root zone of grasses and crops, which will be stripped and stockpiled sepazately. By using <br />concurrent reclamation techniques, the topsoil is not expected to remain in stockpiles for more <br />than one to two yeazs. If the stockpile remains more than one growing season, it will be seeded <br />with a fast growing vegetative cover to prevent erosion. All topsoil will be retained on-site to <br />reclaim the reservoir shoreline, replacement wetlands, and other areas disturbed by mining <br />activities. Where required, topsoil will be replaced to a minimum depth of approximately six <br />inches. <br />When necessary, shipped 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 />Reveeetation <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 <br />dispose of it in a safe and non-erosive manner. <br />Upland Areas. For disturbed upland areas, the reclamation plan includes re-vegetating with <br />appropriate seed mixes to minimize erosion and reestablish natural terrain. The grass mixture <br />below was selected to be long lasting and regenerating. The ground will be fine graded prior to <br />seeding and fertilizers will be applied according to recommendations from the Soil Conservation <br />Services. Reservoir side slopes below the anticipated reservoir water level will not be seeded. <br />Based on the soils in the area, the following upland seed mixture is recommended: <br /> <br />U land Grass Seed Area Cover <br />(% Application Rate <br />#PLS/acre <br />Vau Side Oats Grama 30% 1.35#PLS/ac. <br />Grenville Switch ss 20% 0.5 #PLS/ac <br />Lovin on Blue Grama 20% 0.3 #PLS/ac <br />Barton Western Wheat ass 30% 2.4 #PLS/ac <br />Application rate is for drilling the seed. If seed is to be broadcast, <br />the a lication 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 />If a significant invasion of noxious weeds occurs after seeding, the weeds will be mowed before <br />they can go to seed. The areas will be mowed periodically for additional control as needed. <br />fl onenberg Lakes <br />DMG 1 /1 Pennir <br />Page 1 <br />
