6.4.7 Exhibit G <br />Water Information <br />Mining is expected to have no impact on the prevailing hydrologic balance. <br />Groundwater will not be exposed; therefore, a Substitute Water Supply Plan will not <br />be necessary. <br />Colorado Division of Water Resources database indicates wells in the vicinity <br />experience groundwater at an approximate depth of 30 feet or more. Russell Lake <br />is more than one mile downgradient from the site. Small surface water lakes are <br />located less than 1/2 mile downgradient from the site on ranch property (Exhibit C -4). <br />Runoff occurs as overland flow and snow melt. Stormwater best management <br />practices such as waddles, straw bales, and perimeter berms will be placed to <br />effectively manage stormwater. Historic flow will be maintained during mining. <br />Consumptive use of water may occur as dust suppression on the haul road <br />and working face. All Rite Paving & Redi -Mix Inc. will purchase the necessary volume <br />of water from an appropriate supplier. The amount required for dust suppression is <br />undetermined at this time. <br />The permittee will complete a stormwater management plan and file a <br />stormwater discharge application with Colorado Department of Public Health and <br />Environment, Water Quality Division. Diversionary berms and impoundments will be <br />constructed as recommended by the Water Quality Division. <br />Page 8 of 21 <br />
