Mining is expected to have no impact on the prevailing <br />hydrologic balance. Colorado Division of Water Resources database <br />indicated no water resources in the area. Groundwater will not be <br />exposed; therefore, a Substitute Water Supply Plan will not be <br />necessary. Wells do not exist within 200 feet of the proposed permit <br />area. <br />Runoff occurs as overland flow to vegetated dry creek beds or <br />drainage ravines in the vicinity. <br />Consumptive use of water will be as dust suppression on the <br />haul road, stockpiles and working face. GCC Rio Grande, Inc. will <br />purchase the necessary volume of water from an appropriate supplier. <br />The amount required for dust suppression is undetermined at this <br />time. <br />The permittee will complete a stormwater management plan and <br />file a stormwater discharge application with Colorado Department of <br />Public Health and Environment, Water Quality Division. Diversionary <br />berms and impoundments will be constructed as recommended by the <br />Water Quality Division. <br />Page 13 of 34
