the surface facility area. In addition, erosion control measures will be used to prevent stockpiled <br />topsoil from being washed away into the ephemeral stream to the west of the surface facilities <br />area. <br />Specifically, topsoil stockpiles will be contoured, furrowed, and broadcast seeded in late fall with <br />a crested wheatgrass seed mixture. Efforts to establish vegetation on the topsoil stockpile will <br />continua until vegetation is established equivalent to the existing vegetation conditions in the <br />area. Current vegetation in undisturbed areas of the Topaz Mine is sparse and is further described <br />in Exhibit J. <br />Sediment controls (i.e. grass buffer areas, earthen berms, straw bales, etc.) will be installed and <br />maintained, as necessary, to prevent surface runoff from mine operational areas and roads from <br />running onto the topsoil piles within the surface facilities area. Vegetation success on the <br />stockpiles will be monitored and stockpiles will be reseeded where vegetation is sparse. Best <br />Management Practices (BMP) for preserving soil quality and enhancing soil material for later <br />reclamation and post-mine bond release success will be incorporated into interim topsoil <br />management as they become available during the life of the operation. <br />Ore Stockpile Area -Ore will Typically be end-dumped directly into ore stockpiles in the ore <br />stockpile area, located in front of the portal entrance. The ore will be loaded for transport to the <br />mill when 1,000 to 4,000 tons of ore are available in the ore stockpiles. As such, long-term ore <br />storage will not occur at the Topaz Mine. The ore will be loaded, using a front end loader, into <br />22-ton, over-the-road haul trucks for transportation to the mill. Ore transportation is expected to <br />be primarily limited to weekdays with no ore being shipped on weekends or holidays per the San <br />Miguel County Special Use Permit; however, extreme circumstances, such as weather, may <br />require transportation on the weekend. Should transportation occur on a weekend, Denison will <br />notify the BLM, Colorado Division of Reclamation, Mining and Safety (DBMS), and the San <br />Miguel County Road and Bridge Department. The truck beds will be covered with tarps to <br />prevent fugitive dust emissions. In addition to the land management requirements of BLM, the <br />Sunday Mine Complex meets the extensive and comprehensive regulatory requirements of the <br />CDPHE, the Department of Transportation (DOT), and the Mine Safety and Health <br />Administration (MSHA). More specifically, all aspects of environmental protection, public <br />health and employee safety are regulated by means of separate regulatory venues as it relates to <br />the mining, handling, and transportation of uranium and vanadium ore. Denison has implemented <br />a variety of monitoring and material control programs that are responsive to these regulatory <br />S-IS-2007 Exhibit D Mining Plan D-$ <br />
