6.4.7 Exhibit G <br />Water Information <br />Mining is expected to have no impact on the prevailing hydrologic balance. <br />Colorado Division of Water Resources database indicated no water resources in the <br />area. Groundwater will not be exposed; therefore, a Substitute Water Supply Plan <br />will not be necessary. Wells do not exist within 200 feet of the proposed permit <br />area. <br />Runoff occurs as overland flow to natural drainage ravines in the vicinity. <br />Stormwater best management practices such as waddles, straw bales, sandstone <br />slaps and perimeter berms will be placed to effectively manage stormwater. Historic <br />flow will be maintained during mining. <br />Consumptive use of water may occur as dust suppression on the haul road <br />and working face. Minimal working face dust will be created since the target <br />material will be extracted as large pieces and no crushing or screening will occur on <br />site. KrauthCo, Inc. will purchase the necessary volume of water from an <br />appropriate supplier. The amount required for dust suppression is undetermined at <br />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 9 of 25 <br />Revised 3/14/2011
