Topsoil will be stripped to a depth of at least 12" and will be stockpiled around the perimeter of the pit. <br />Topsoil will be seeded with native grass species to help preserve the soil's viability and to protect it from <br />wind and water erosion. Grass, shrubs, and small trees will be stripped and incorporated into the topsoil <br />piles of will be stockpiled separately for later use as a mulch. <br />The pit area receives approximately 11' -14' of precipitation per yeaz. Surface water is generally not <br />present in the permit area. The mining operation will not intersect any sources of goundwater. During <br />operations, the pit will be termed with material piles or topsoil piles to contain any overland flow from <br />stone events. <br />The mine life is approximately ten to fifteen (10-15) years. No mining will occur from November 15 to <br />April I S to avoid conflict with wildlife on their wintering areas. Due to the small staging area and pit area <br />there will be limited sequential reclamation during operations. As mining progresses to the south, the <br />staging area will also shift toward the south. Reclamation work will begin at the north end of the project <br />area and will progress toward the south as mining progresses and as space allows. <br />Mining equipment will consist of two crushing units, one pre crushing jaw crusher and one final cone <br />crushing unit, one front end loader, one crawler tractor and three support van trailers. Crushed materials <br />will be stockpiled at the northwest end of the pit. Typically gravel hauling from pit will be done with a <br />fleet of 5 belly dumps, hauling from 7:00 A.M. to 5:00 P.M. Monday thru Friday. Most years will see a <br />two week steady haul per season with occasional hauling during summer months for general maintenance <br />A steel gate with warning signs will be placed at the entranced to the pit to restrict access to unauthorized <br />personnel. The pit will be patrolled on regulaz bases to inspect for damage and to remove litter and illegal <br />dumping. All noxious weeds will be controlled by Grand County through an authorization with the BLM. <br />No inoperable equipment or equipment not related to the mining operation will be stored at the site. <br />Grand County is submitting the above amended Mining Plan For your comments and review. No change <br />in mining operations will be implemented without the approval of both the BLM and the Division of <br />Mineral and Geology. We await your decision. <br />Sincerely, <br />Billy L./Clark, Assistant Superintendent <br />
