EXHIBIT "G" <br />6.4.7 Water Information: <br />(1) Impact to ground water: <br />The proposed mining operation will result in a pond as the primary post mining land use. <br />Since this is an unlined pond, once reclamation is complete, the operation will not affect <br />the ground water flow regime. (Ground water will flow into the pond up-gradient and <br />exit the pond down-gradient.) During mining, reclamation and post reclamation, the <br />operation will not affect ground water quality or have unauthorized uses of ground water, <br />i.e. water rights. <br />As is currently the case, there is some impact to the ground water now regime. The <br />Hogue River Pit must dewater (pump) ground water to its water treatment pond to <br />remove sediment prior to its approved discharge back to the Yampa River. There is some <br />loss of ground water due to evaporation from product piles and product processing. <br />These losses are accounted for in the Operations approved water rights secured through <br />agreements with HRLP. <br />The ground water dewatering system currently in use is as follows. A trench and sump <br />station (electric submersible pump) is located near the eastern permit boundary. Water <br />• from this pump station is used in the wash plant. The wash water is then directed to a <br />settling pond to remove sediment and then recycled back to the pump for reuse. <br />A second pump is located near the northeast corner of the mining area. This pump pulls <br />water from a trench running east to west on the pit floor. This trench dewaters in situ <br />water from the sand and gravel resource. <br />A third pump located in the southwest corner of the mining area is also used to dewater <br />the gravel resource. Dewatering prior to mining will lower the water table in the mining <br />area and dewatering the gravel in its natural, undisturbed condition. This method <br />provides for cleaner water and minimizing the production of suspended sediments. <br />Captured ground water not needed for product processing or for dust control is <br />discharged into the Hogue Ranch irrigation system or the Duquette Ditch, which then <br />flows into the Yampa River, Colorado Wastewater Discharge Permit Number COG- <br />500243. (The Duquette Ditch runs along the eastern edge of the permit boundary.) <br />(2)(a) If the operation is expected to directly affect surface or ground water <br />systems, then locate water structures facilities, etc. on Exhibit "C": <br />All such structures and facilities have been placed on Exhibit "C" to the best of the <br />Operator's knowledge. <br />Page 29
