EXHIBIT G <br />Water Information <br />The River Valley Resource site is located in Routt County north and east of the Yampa River, <br />just south of the City of Steamboat Springs. The consumptive use of groundwater from proposed <br />mining activities will only have a minor impact on the Yampa River. The impacts can be <br />mitigated without injury to senior water rights. <br />The Pre-Mining/Mining Plan Map (Exhibit C) illustrates water resources on the site. The Yampa <br />River is located to the south and west of the site. The site does not contain any other active <br />irrigation structures that convey water outside of the site boundary. <br />Mining of the River Valley Resource site will occur in 6 mining phases and last approximately <br />13 to 15 years. Reclamation will occur concurrent with mining operations. Reclamation of the <br />site will include the construction of mitigation wetlands and the resultant groundwater lakes area <br />of approximately 91 acres. <br />The deposit will be dry mined. Dewatering trenches and pumps will be used to dewater the <br />deposit prior to mining below the water table. Dewatering trenches will be excavated around the <br />perimeter of each phase prior to mining and pumps will be used to remove the water that drains <br />from the deposit and surrounding alluvium into the trench. If necessary, water from the trenches <br />will be circulated through a settling basin prior to it being discharged into the Yampa River. <br />As each of the 6 phases will be dry mined, groundwater will be exposed in dewatering trenches <br />and collection basins. Groundwater and stormwater will flow along trenches by gravity to the <br />collection basins. Prior to discharge into the Yampa River, the collected groundwater and/or <br />stormwater will be evaluated for the presence of contaminants. <br />Some of the excavated material will be processed on-site. Once material is recovered, some will <br />be transported to a crushing and screening plant to be prepared for use in a concrete or asphalt <br />plant. The rest will be used as pit run material. <br />The mining operation will impact groundwater systems hydrologically connected to the Yampa <br />River. The depth to groundwater ranges from approximately 0 to 5 feet across the proposed site <br />and, therefore, the operation will extract sand and gravel deposits from the Yampa River alluvial <br />aquifer. This reach of the Yampa River is not fully appropriated at this time. <br />River dal/ey Resource <br />DMG 1(2 Permi(Amendmen( <br />Pnge R <br />
