Reclamation Measures/Materials Handling <br />Backfilling will be done to provide stabilized shorelines around the reservoir and to minimize <br />erosion. The backfill material will consist of native bedrock claystone, overburden, and topsoil. <br />There will not be known toxic or hazardous materials in the backfill material. Additionally, it is <br />not likely that acid forming or toxic materials will be encountered during mining. The mining <br />will not leave high walls on the property. In addition, there will be no auger holes, excavations, <br />or shafts left on the property. <br />Top soiling <br />The top six 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 one to <br />two 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 />reservoir shoreline, and other areas disturbed by mining activities. Where required, topsoil will <br />be replaced to a depth of approximately four to six inches. <br />Reve etg~ ation <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 or channels will be constructed to divert excess water <br />and 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 Natural Resources <br />Conservation Service. Reservoir side slopes below the anticipated reservoir water level will not <br />be seeded. Based on the soils in the area, the following upland seed mixture is recommended: <br /> <br />Upland Grass Seed Area Cover <br />(%) Application Rate <br />(#PLS/acre) <br />Vaughn Side Oats Grama 30% 1.35#PLS/ac <br />Grenville Switchgrass 20% 0.5 #PLS/ac <br />Covington Blue Grama 20% 0.3 #PLS/ac <br />Barton Western Wheatgrass 30% 2.4 #PLS/ac <br />Application rate is for drilling the seed. If seed is to be broadcast, the <br />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 />.~eia~w a ~~.-. <br />DBMS 112 Permit <br />Page 8 <br />
