The existing mine access road connects county road DD-16 to the existing haul road and <br />stockpiles. The road is about 15 feet wide and 500 feet long. <br />Once operations at the mine are complete, a reclamation plan will be developed which is <br />consistent with CDPHE stormwater, DBMS, and BLM, requirements. <br />2) Materials handling and spill prevention: The temporary ore stockpile and loading area are <br />designed for total containment by returning precipitation from a 100-year 24-hour event back into <br />abandoned workings within the mine. Furthermore, the ore will be transported to the mill every <br />day so its exposure to the effects of weathering will be minimal. <br />Limited volumes of toxic chemicals (lubricants, anti-freeze, grease, etc.) for vehicles and <br />equipment will be stored in approved containers in the locked storage/office trailer. Mining <br />explosives will be stored in a MSHA approved underground "powder magazine". Nuvemco will <br />be responsible for obtaining permits and for proper management of these materials. All fuels and <br />lubricants used in vehicles on location will be transported to the site as needed by mine personnel. <br />c. Preventive Maintenance <br />Periodic inspections will reveal the need for preventive maintenance of stormwater BMPs. The <br />inspection schedule is discussed below in Section 5. <br />Silt fences and wattles must be inspected regularly and following significant rainfall events to <br />determine the need for repair or replacement. Accumulated sediment must be removed from <br />these devices to maintain their effectiveness during future stormwater runoff events. Periodic <br />removal of sediment from the sediment pond as well as sediment traps and check dams/rock <br />berms will also be required. <br />Diversion berms and ditches will need to be regularly inspected and repaired as needed so that <br />they continue to function effectively. <br />d Good Housekeeping <br />The following practices will be adopted to ensure that the site is maintained in a neat and orderly <br />condition: <br />• Vehicles and equipment will be inspected for drips and leaks and repaired as needed. <br />• Adequate closed containers will be provided for garbage which will be removed on a <br />regular basis to an approved landfill. Hazardous and petroleum wastes will be stored <br />separately and hauled to an approved facility as soon as possible. <br />• A portable toilet will be located near the office trailer. It will be maintained and emptied <br />on a regular schedule by a sanitary waste disposal company. <br />• Spilled materials will be cleaned up as soon as practical following their discovery. <br />Absorbent pads and booms will be kept on site for this purpose. Cleaned up substances <br />and materials used for clean up will be placed in a proper receptacle and hauled to an <br />approved disposal facility as soon as possible. <br />• No abandoned machinery or parts will be left at the site. <br />• Volumes of hazardous materials and petroleum products stored on site will be minimized <br />so that only those quantities needed are kept on site. <br />• Oil changes, lubrication, adding antifreeze and other repairs for haul buggies, a front-end <br />loader, and other equipment will be performed in a designated parking area adjacent to <br />the office trailer. Drip pans, tarps, and absorbent pads will be used to minimize the risk <br />5
