not expected to remain in stockpiles for more than one to two yeazs. If the stockpile remains <br />more than one growing season, it will be seeded with a fast growing vegetative cover to prevent <br />erosion. All topsoil will be retained on-site to reclaim the backfilled mine cell and other areas <br />disturbed by mining activities. Where required, topsoil will be replaced to a depth of <br />approximately four to six inches. <br />When necessary, stripped topsoil will be stockpiled pazallel to potential flood flows to reduce the <br />risk of inhibiting the flow. Throughout the mining and reclamation phases, the amount of topsoil <br />stockpiled will be limited by continuously using it to cap backfilled azeas. <br />Reve etation <br />As mining operations are completed, azeas 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 backfilled or disturbed upland azeas, the reclamation plan includes <br />revegetating with appropriate seed mixes to minimize erosion and reestablish natural terrain. <br />The grass mixture below was selected to be long lasting and regenerating. The ground will be <br />fine graded prior to seeding and fertilizers will be applied according to recommendations from <br />the Soil Conservation Services. Groundwater lake side-slopes below the anticipated water level <br />will not be seeded. Based on the soils in the area, the following upland seed mixture is <br />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 ass 20% 0.5 #PLSIac <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 gals 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 />Mechanical control will be used as a first priority. Chemical methods will only be used if no <br />other alternative produces acceptable results. <br />Wetland Areas. The replacement wetland areas and azeas to be used for future wetland banking <br />will be planted and seeded with native wetland plants.
