Please inform the Division how topsoil/overburden piles will be <br />protected from the mining operation. If the pit is to be mined adjacent <br />to the piles, the topsoil piles may become unstable and slop failure <br />may occur if an adjacent buffer distance is not established. <br />The County intends to relocate existing topsoil piles around the <br />existing pit to a location on the east end of the permitted property. This <br />location is best suited for this interim purpose as it will be the last area <br />to be mined. As mining operations on the west end of the property <br />occur and prior to extraction of material on the east end of the <br />property, it is the intent of the County to begin reclamation operations <br />on the West end utilizing topsoil stockpiles from the east. As mining <br />progresses westerly from the existing pit, the topsoil/overburden will be <br />striped back a minimum of 2 times the depth of the pit. And the <br />open/working face of the pit will be sloped down away from the <br />topsoil/overburden piles at a maximum of 4h:1v slope. <br />Topsoilloverburden will not be stripped off until mining progress <br />towards storage piles. Also as mining progresses Westerly, North and <br />South boundary lines will be utilized as topsoil/overburden storage <br />areas with a minimum 50 ft buffer zone along the property lines. <br />Lake County Half Moon Pit <br />#M-77-071 <br />Lake County, Colorado
