WILLIAMS FORK MINING COMPANY <br /> SAND AND GRAVEL SITE <br /> Exhibit G.......... Water Information <br /> 1.0 Water <br /> All applicable water laws will be upheld. If necessary NPDES monitoring for the site will be <br /> conducted as stated in the NPDES permit(No. CO-G500062). It is anticipated, however, that all <br /> runoff will be contained in existing reclaimed ponds and no discharges to the river will occur. If in <br /> the unlikely event discharge does occur, it is expected that NPDES standards can be met without <br /> a settling pond. However, if this is not the case, then a settling pond will be constructed. The <br /> gravel pit will be constructed in alluvial material from the Yampa River. As a consequence, <br /> tributary ground water from the river will be continually moving in and out of the pit. This interme- <br /> diate containment of water will have a negligible effect on the quantity of water in the Yampa <br /> River. <br /> Some use of water will occur due to fugitive dust control activities required by the Colorado <br /> Department of Public Health and Environment fugitive dust emission permits. Williams Fork <br /> Mining Company holds sufficient water rights to cover these activities if it should be necessary to <br /> use them. Williams Fork Mining Company holds well permit 033422-F from the Office of the <br /> State Engineer for an open pit well which makes beneficial use of non-tributary ground waters. <br /> Total consumptive use will be for fugitive dust control for haul roads, yard area, and product han- <br /> dling. Table G-1 documents the approximately number of acre-feet of water needed annually for <br /> the above losses. According to available data, a total of.66 acre-feet of water will be consumed <br /> annually. <br /> FVL/tsh 4/19 <br /> [s9permit] <br /> Revision: -T e--0 q <br /> Approved: - _- <br />
