b. Ore Stockpile <br />The ore stockpile will be located on the second tier of the waste rock pile <br />approximately 80 feet west of the portal. Currently there is no ore stored on site. <br />During active mining the ore will be piled up to a workable stockpile and hauled <br />to the mill using a first in, first out system. Ore will be stored onsite for no more <br />than 30 days after mining operations cease. <br />Design components (BMPs) will be employed to prevent cumulative collection <br />and infiltration of potential constituents of concern into the substrata. These <br />design components include a clay liner, limited contact time, and surface water <br />controls (ditches and berms). (For a description of the ore pad liner, see <br />Exhibit T - EPP). <br />A contractor will be used to haul the ore from the surface ore stockpile area to the <br />mill. The ore haulage contractor will be responsible for a spill control plan. <br />c. Soil Excavation and Stockpile Areas <br />Top soil will be borrowed from the toe of the hill located northwest of the mine <br />waste dump and spread over the waste and ore stockpiles at a thickness of 1 to 2 <br />inches. This site has already been successfully reclaimed previously using topsoil <br />spread to a thickness of less than 2 inches in places; it can be expected that the <br />same method will work again. <br />d. Surface Drainage Control Structures <br />Berms and ditches will be constructed around portions of the site perimeter of the <br />waste rock, ore and soil stockpiles to divert onsite runon away from these piles. <br />Runoff from these piles will be contained onsite. <br />For a detailed description of all stormwater diversion structures and maps, see <br />Appendix II - Drainage Design Plan. <br />e. Fuel and Oil Storage Areas <br />A 500 - gallon fuel storage tank will be brought onsite once mining resumes. A <br />lined secondary containment adequate to contain 120% of the tanks contents will <br />be constructed beneath the tank. <br />No large quantities of oil will be stored onsite. When mining activity resumes, it <br />may be necessary to store small quantities (5- gallon buckets) of antifreeze, motor <br />oil, gear oil, hydraulic oil, rock drill oil, etc. This will be stored in the compressor <br />shed. Used oil will be hauled off site and properly disposed. <br />C -5 <br />
