no visible signs of slope failure are detected during mining, reducing visual inspections to once <br /> every six months after mining completion, or after every major precipitation event. <br /> During reclamation activities, inlet and outlet facilities for the reservoir will be designed and <br /> installed once the operational criteria of the proposed reservoir have been identified by an end <br /> user. <br /> 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 gravel, overburden, and topsoil. There will not be <br /> known toxic or hazardous materials in the backfill material. Additionally, it is not likely that acid <br /> forming or toxic materials will be encountered during mining. The mining will not leave high walls <br /> on the property. In addition, there will be no auger holes, excavations, or shafts left on the <br /> property. <br /> Topsoil will be placed to finalize the grading such that seeding can occur. The topsoil will be <br /> placed at all disturbed areas and on the mining slope to an elevation matching the expected <br /> reservoir water level. <br /> Topsoiling <br /> Approximately the top twelve inches of soil on the property is classified as topsoil. This layer <br /> includes the root zone of grasses and crops, which will be stripped and stockpiled separately. <br /> By using concurrent reclamation techniques, the topsoil is not expected to remain in stockpiles <br /> for more than one to five years. If the stockpile remains more than one growing season, it will be <br /> seeded with a fast-growing vegetative cover to prevent erosion. All topsoil will be retained on- <br /> site to reclaim the reservoir shoreline, and other areas disturbed by mining activities. Where <br /> required, topsoil will be replaced to a depth of twelve inches. <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 or channels will be constructed to divert excess <br /> water and convey it in a safe and non-erosive manner. <br /> For disturbed areas, the reclamation plan includes re-vegetating with appropriate seed mixes to <br /> minimize erosion and re-establish natural terrain. The seed mixture below was selected to be <br /> long lasting and regenerating, as recommended by the Greeley Natural Resource Conservation <br /> Service Office (see attached recommendation). The ground will be fine graded prior to seeding <br /> and mulch will be applied according to recommendations from the NRCS. Reservoir side slopes <br /> below the anticipated reservoir water level will not be seeded.
