Water Information <br />Exhibit G <br />Further discussions on the relationships of aquifers with respect to the mining <br />operations are presented in Exhibit U, Section 6.4.21(8). A geologic cross section <br />is shown as Figure U -3. <br />(c) Water management and monitoring <br />(i) Stormwater management <br />Water runon/runoff will be managed to protect surface water and <br />groundwater resources under a CDPS General Permit for Stormwater <br />Discharges (see Section 6.4.7(5)). <br />(ii) Surface water and groundwater monitoring <br />Monitoring activities are planned to be conducted in the following phases <br />and in accordance with the Joint Stipulations and Rules 6.4.21(9) and <br />6.4.21(11). <br />Wildcat proposes to mobilize a drill rig to the site to drill two wells for the <br />purpose of groundwater quality sampling, monitoring, and as a point of <br />compliance (Figure G -1). <br />Ambient groundwater quality data will be collected from the point of <br />compliance well and other monitoring points. The point of compliance <br />monitoring well (WW -2) is located on the May Day No. 2 bench. Other <br />groundwater monitoring points include the monitoring well WW -1 north <br />of Idaho No. 1 spring and a proposed groundwater production well at the <br />May Day No. 1. The wells are located to determine the depths to <br />groundwater, flow direction and gradient, and provide samples for <br />baseline and on -going groundwater quality characteristics. Quarterly adit <br />water samples will also be if discharges are observed. <br />The wells will be drilled to first water or to a depth not to exceed 300 feet <br />below the elevation of the La Plata River. If water is encountered a 4 to 6 <br />inch well will be completed and tested for production yields and water <br />quality. Wildcat will continue groundwater monitoring on a quarterly <br />basis to characterize and monitor seasonal groundwater quality, flow <br />direction, and rate. Wildcat may seek a determination after two quarters <br />of groundwater monitoring, in the event it confirms that ground water <br />quality is the same as surface water and spring water sampled during the <br />past five quarters, that baseline groundwater quality has been adequately <br />Wildcat Mining Corporation <br />May Day Idaho Mine Complex — 112d Permit Application <br />Revised August, 2011 <br />Exhibit G — Rule 6.4.7 <br />Page 4 of 6 <br />
