impacts to local or off-site locations are expected. All <br />excavations will be made in areas physically separated from <br />flowing water by streambed material or temporary isolation <br />dikes built after spring runoff, thus preventing disturbed <br />sediment from entering the river. Individual mining <br />operations will typically encompass areas of approximately <br />13 acres at any one time, and would be performed utilizing <br />a variety of equipment, including front-end loaders, <br />scrapers, bulldozers, draglines, trucks, conveyor belts, <br />etc., as necessary. Haul roads built on high sand and <br />gravel bars within the river channel would involve an <br />additional area which would vary, depending upon the mining <br />location. No haul road wculd be routed through flowing <br />water, and to further reduce possible water quality impact, <br />all excavated materials will to hauled to the stockpile and <br />processing area shown in Exhibit "C". As soon as feasible <br />after each annual mining operation, and prier to high water <br />floras, all isolation dikes a.nd haul roads will be removed <br />to conform with the existing streambed, thus producing no <br />more impact than normal streambed movement during high <br />water periods. Every reascnable effort will be made to <br />prevent pollution and disturbe.nce of the hydrologic balance <br />of the river system. Further, every effort will be taken <br />to assure the safety and protection of wildlife at the site <br />and recommendations of the Colorado Division of Sildlife <br />will be observed. <br />3 <br />~i <br />
