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, clay, and topsoil from on-site <br /> materials. There will not be known toxic or hazardous materials in the backfill material. <br /> Additionally, it is not likely that acid forming or toxic materials will be encountered during mining. <br /> The mining will not leave high walls on the property. In addition, there will be no auger holes, <br /> excavations, or shafts left on the property. The auger holes for the gravel investigation were <br /> backfilled with native gravel and soil cuttings from the drilling. The auger holes that were not <br /> backfilled were the four monitor wells that were constructed and permitted as permanent <br /> monitoring wells to monitor groundwater at the north, east, west, and south sides of the permit <br /> boundary. Monitor wells will remain on the property so the end user may continue to monitor <br /> levels of the groundwater elevations. <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 /> Topsoilinq <br /> Approximately the top six 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 /> Topsoil will be re-handled as little as possible and a Technical Revision will be submitted prior to <br /> re-locating topsoil stockpiles. By using concurrent reclamation techniques, the topsoil is not <br /> expected to remain in stockpiles for more than one to five years. If the stockpile remains more <br /> 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 reservoir shoreline, and other areas <br /> disturbed by mining activities. Where required, topsoil will be replaced to a depth of twelve <br /> inches. Prior to placing topsoil uneven areas and low spots will be graded to subgrade <br /> elevation, in addition debris, roots, branches, stones, in excess of 2 inch in size will be removed. <br /> Scarify surface to depth of 8 inches where topsoil is to be placed for a roughened condition to <br /> assist in eliminating erosion. Scarify/cultivate in areas where equipment used for hauling and <br /> spreading topsoil has compacted subsoil. Place topsoil during dry weather and on dry unfrozen <br /> subgrade. Remove vegetable matter and foreign non-organic material from topsoil while <br /> spreading. Grade topsoil to eliminate rough, low or soft areas. <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. A proper seedbed is firm and free of <br /> competing vegetation. Correct firmness is when an adult footprint is only slightly visible on the <br /> prepared bed prior to the seeding operation. The seedbed can be firmed, if needed, by pulling a <br /> commercial or homemade packer or roller. A firm seedbed is essential for proper seeding depth <br /> J&T Consulting,Inc.
