.... <br />EXHIBIT C - h1INING PLAN <br />1. Mining will begin March 1, 1987 and end in 1992. <br />2. Topsoil material will be removed to a depth of 6 to 8 inches <br />or deeper where found in pockets. On the west half of the <br />proposed site little or no topsoil will be found. However, <br />where found it will be removed by self-propelled scrapers and <br />stockpiled in an orderly berm along the west boundary. The <br />stockpile will be seeded to the same grass seed mixture as <br />described in the Reclamation Plan if the stockpile is to <br />remain more than one growing season. <br />3. There is no overburden or waste material expected on the site. <br />4. The deposit is expected to be about 3 feet deep on the west <br />and about 15 feet deep as mining proceeds into the hillside to <br />the east. <br />5. The only equipment on site will be the self-propelled scrapers, <br />a dozer, wheeled front-end loaders, the crusher and screen, and <br />necessazy conveyors. Material will be hauled from the site on <br />trucks. <br />6. The ~;ite demensions are generally 480 feet by 900 feet. The <br />excavation will encompass virtually all of the site. The mine <br />floor will be generally level and side slopes will be graded to <br />2:1 or flatter in the course of mining. <br />7. The :;ite will be accessed via an existing farm road used for <br />farm machinery and to service the windmill and pasture beyond the <br />site. No additional haul roads will be constructed. <br />8. No wzcter will be used on site and all mining will halt well <br />above ttie water table. <br />9. The 7.ittle surface water that might occur on-site will most <br />likely t>e immediately absorbed into the exposed gravel floor. <br />Any pos:;ible runoff will be contained on the west boundary by <br />the topsoil berm and/or' the shallow excavation (about aft. deep) <br />along the west side of the pit. <br />10. N.A.. <br />11. As doted in 5 above, the material will be crushed if needed, <br />screened and stockpiled. The limited size of this operation <br />required no additional controls. <br />
