Mayday Mine and Mill Site, Wildcat Mining Corporation, Original 110(2) Permit <br />Exhibit D <br />If acid - forming or toxic - producing materials are encountered during mining or reclamation activities, <br />Wildcat will isolate the material above the water table, within the old mine workings or encapsulate the <br />material. The material will be capped with two feet of suitable material, top soiled and revegetated as <br />outlined above. (Rule 3.1.5(5)) <br />Topsoil from historical mining activities was not salvaged because the topsoil is thin and because of the <br />inability to effectively utilize topsoil salvaging equipment on the steep slope. Disturbed areas will be <br />reclaimed and to the extent possible scarified, mulched, top soiled and revegetated). Available topsoil or <br />suitable subsoil will be applied at a depth of six inches when available. Soil tests will be conducted <br />before seeding to confirm that fertilizers are not required to meet reclamation obligations. It is not <br />anticipated that any soil amendments or fertilizer will be required. (Rule 6.3.4 (1) (c)) <br />United States Department of Agriculture (USDA) recommends (Rule 3.1.10 (1)) 6.5 pounds (lbs) pure <br />live seed pounds per acre for reclamation purposes (Attachment D -1). (Rule 3.1.10) As broadcast seeding <br />methods will be used due of the steepness of the site, the seeding rate will be doubled to 13.0 pure live <br />seed pounds per acre. (Rule 3.1.10(5)) The most desirable time for seeding is very late fall so the <br />anticipated seeding will occur in October of each year. Mulching will be used per requirements of the <br />USDA due to the steepness of the area. The area seeded will be mulched with 4,000 lb /acre of native <br />grass, hay or straw. Access by wildlife and people will be limited until new vegetation is established. <br />Irrigation and soil amendments will not be applied to reclaimed areas not specifically identified within <br />the Mayday reclamation permit. Noxious weeds will be eradicated from the revegetated area using <br />approved NRCS methods and certified personnel as approved by the Division. (Rule 6.3.4 (1)(2) and Rule <br />3.1.10(6)) Engleman spruce, Ponderosa Pine and Lodgepole Pine seedlings will be planted at 10 foot <br />centers on appropriate locations with the terraces on the mine and mill site. <br />Measures taken to minimize disturbance to the hydrologic balance, to prevent off -site impacts, to provide <br />for stable configuration consistent with the proposed future land use have been incorporated into the <br />scoping and design of reclamation activities. The anticipated future land use for the Mine and Mill site is <br />grazing (domestic and wildlife) and/ or recreational use (Rule 3.1.1). <br />Reclamation Costs (Rule 6.3.4(2) <br />The estimated costs to reclaim the Mayday and Mill site and the pre- existing access road are summarized <br />in Attachment D -2. <br />
