6.4.7 Exhibit G <br /> Water Information <br /> Mining is expected to have no impact on the prevailing hydrologic balance. <br /> Groundwater will not be exposed, and stormwater will not leave the site. The site will not <br /> discharge stormwater or process water drainage. Water depth is anticipated to be greater than <br /> the 20 feet mining depth, as noted below with a nearby depth recorded at 381 feet. <br /> COLORADO'S <br /> Decision Support Systems Map Viewer <br /> r 3 wCt,!MN <br /> < Quick Tools <br /> Structure(Admin/Decreed) Well Constructed 284993- x <br /> 993 <br /> Y <br /> Structure(Points of Interest) - • <br /> Q Well Application •• .. <br /> Final Permit <br /> • Ground Water <br /> Surface Water Current Conditions <br /> Surface Water Station(Historic) <br /> ,1009, <br /> Livestock Water Tank/Erosion <br /> Runoff occurs as overland flow to natural drainage ravines in the vicinity. Stormwater <br /> best management practices such as waddles, straw bales, and perimeter berms will be placed <br /> to effectively manage stormwater. Historic flow will be maintained during mining. <br /> Consumptive use of water may occur as dust suppression on the haul road and affected <br /> areas. The operator will purchase the necessary volume of water from an appropriate supplier <br /> and transport to the site for use. It is anticipated that the site could use up to 10,000 gallons <br /> per day. <br /> The permittee will complete a stormwater management plan. Diversionary berms and <br /> impoundments will be constructed as recommended by the Water Quality Division. <br /> Page 9 of 17 <br />
