Reclamation Measures/Materials Handlinq <br />Backfilling will be done to provide stabilized shorelines around the reservoir and to <br />minimize erosion. The backfill material will consist of native bedrock claystone, gravel, <br />overburden, and topsoil. There will not be known toxic or hazardous materials in the <br />backfill material. Additionally, it is not likely that acid forming or toxic materials will be <br />encountered during mining. The mining will not leave high walls on the property. In <br />addition, there will be no auger holes, excavations, 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 <br />root zone of grasses and crops, which will be stripped and stockpiled separately. By <br />using concurrent reclamation techniques, the topsoil is not expected to remain in <br />stockpiles for more than one to five years. If the stockpile remains more than one <br />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 reservoir shoreline, and other <br />areas disturbed by mining activities. Where required, topsoil will be replaced to a depth <br />of approximately four to six inches. <br />Revegetation <br />As mining operations are completed, areas for reclamation will be graded and shaped <br />for revegetation. Runoff or excess water from adjacent areas will not be allowed to flow <br />over slopes being graded and seeded. If needed, berms or channels will be constructed <br />to divert excess water and dispose of it in a safe and non-erosive manner. <br />Upland Areas. For disturbed upland areas, the reclamation plan includes re-vegetating <br />with appropriate seed mixes to minimize erosion and reestablish natural terrain. The <br />grass mixture below was selected to be long lasting and regenerating, as recommended <br />by the Greeley NRCS field office. The ground will be fine graded prior to seeding and <br />fertilizers will be applied according to recommendations from the Natural Resource <br />Conservation Service. Reservoir side slopes below the anticipated reservoir water level <br />will not be seeded.
