Groundwater is generally found at River level in the permit area (or slightly above) and will not be <br />encountered in the gold mining operation in the areas shown on Map C -2. The water level in the <br />majority of the mining areas is expected to be encountered approximately 40 -60 feet from the surface. <br />No ground water will be exposed. <br />The water quality of the water in the alluvial gravel is good with acceptable pH, low dissolved solids <br />and virtually no suspended solids. The lode gold deposits and old mines upstream have not contributed <br />significant acid water and/or heavy metals or other ions of concern downstream. Past experience with <br />excavations in this area have shown that the gravel below. <br />There is a well within the permit area (owned by the Operator) called the Sullivan well, which is located <br />at the office/house area. There is one other well within 600 feet of the permit boundary, which is the <br />well adjacent to the residence southwest of the southwest portion of the permit area, as shown on Maps <br />C -1 and C -2. This well will not be affected since no groundwater will be disturbed for this operation. <br />The existing wells will be monitored and communication will be maintained with the landowner, Donald <br />and Jessie Petersen. <br />Section 6. Water Consumption for the Operation and Water Rights <br />The proposed gravel operation will use water for dust suppression on roads and in plants, raw gravel <br />crushing, screening and stockpiling as well as evaporation from the mine excavation pond, the plant <br />settling pond and the infiltration pond. Water will also be consumed in gravel sales. The Table D -2 <br />shows the consumptive uses predicted annually for the site. These uses are well within the 2.0 cfs water <br />right that the permittee has for the property. As shown in Table D -2, water consumptive use annually is <br />predicted to be 3.7 acre feet. <br />Sullivan Aggregate Pit March 2015 H -4 <br />
