~ The ore pad will be sloped toward the sump described above. As shown on Map C-2, the ore pad <br />azea will be surrounded by a gradual sloping berm that will direct all runoff from the ore pad area to <br />the sump. These provisions aze designed to capture and allow for treatment of surface water runoff <br />that may have contacted the uranium ore. As shown in Appendix A, leaching of the ore has the <br />potential to generate elevated levels of uranium, radium, and trace metals. The ore will be stored <br />only temporarily on site and all ore will be removed prior to site reclamation as discussed in Exhibit <br />E. In addition, the top 18 inches of pad material below the ore will be removed and placed in a dry <br />portion of the mine prior to reclamation of the pad. <br />A front-end loader will load the ore into haul trucks. Fugitive dust will be minimal because the ore <br />will have a high moisture content and the loading azea will be treated with magnesium chloride to <br />seal the pad surface. The truck beds will be covered with tarps prior to leaving the mine site to <br />prevent the generation of fugitive dust during haulage. Initially, approximately twenty trucks per <br />week will be loaded and sent to the mill. As production increases to 200 tons per day, truck traffic <br />will increase to an average of about forty roundtrips per week. Weather conditions, haul truck <br />availability, mill demands, and other factors may result in periods of increased haulage of up to <br /> <br />•~ eighty roundtrips per week (i.e., sixteen trips per workday). The primary haulage route will be via <br />Mesa County roads to Colorado Highway 141 just south of Gateway. Three secondary routes via <br />Grand County, Utah roads to Utah highways may also be used, especially in the summer when <br />weather conditions aze more favorable. <br />Ore haulage will be performed by contractors who will be required to: obtain all necessary permits <br />and clearances, follow Department of Transportation regulations including establishment of spill <br />control plans, and obey Colorado and Utah traffic laws. <br />7. Soil Excavation and Stockpile Areas <br />Topsoil Stripping <br />Topsoil will be stripped from all azeas prior to conducting mining or construction activities. This <br />includes both previously reclaimed azeas and previously undisturbed azeas. Pinyon pine, juniper, <br />scrub oak, and any other small trees will be removed from previously undisturbed azeas prior to <br />~~ <br />Whirlwind Mine June 07 D-14 <br />
