10. Ground Water Contro! and Monitoring <br />Reduction of ground water inflows into the mine during mining operations and after mine <br />closure will minimize the potential impacts to ground and surface water in the area. It <br />will also provide cost savings for Energy Fuels by limiting the volume of water that will <br />need to be pumped and treated. Monitoring and ground water characterization will be <br />conducted during and after mine operations, both within the mine and in the two closest <br />aquifers, to create a model of the Iocal ground water system and identify any impacts to <br />ground water that may occur as a result of mining activities. <br />10.1 Ground Water Control Measures <br />Reduction of ground water flows will be accomplished by: (1) implementing an inflow <br />source control program at the start of and during mining operations, and (2) constructing <br />hydraulic seals during closure and reclamation to further reduce ground water inflow <br />from point sources and non-point sources. Details of the proposed ground water control <br />program follow. <br />Point Source Control <br />During mining operations, Energy Fuels will identify those locations where ground water <br />is entering the mine. This will include both point sources and area where seepage occurs <br />over a broader area. Potential point sources consist primarily of historic mining features <br />such. as open exploration holes and un-grouted vent shags and declines. Non-point <br />sources include seepage from fracture systems and more permeable sandstone lenses. The <br />locations and estimated flow rates where ground water is entering the mine workings will <br />be identified and plotted on a map, where possible. <br />Each of the ground water inflow locations will be evaluated to determine whether the <br />inflow can be prevented or reduced in volume as part of active operations or at time of <br />mine closure. Point sources can be plugged or partially plugged by installing packers in <br />
