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 indicate water resources and <br />structures are present within the permit area. The three Jackson permit numbers <br />are incorrectly located with correct locations in the quarter section directly east of <br />the subject property. Mr. Treat, the landowner, owns a well on site. Exhibit S <br />contains a damage compensation agreement for the structure. <br />Runoff occurs as overland flow to vegetated drainage ravines in the vicinity <br />and eventually the Arkansas River. The mine is a pit below natural elevations <br />therefore containing any runoff that comes in contact with the mine operation. The <br />pit floor grade naturally dips to the northeast where stormwater may collect and <br />percolate within 72 hours. Final reclamation will maintain the pit formation. <br />Perimeter berms may be constructed as necessary along the top ridge of the mining <br />face using reject material or overburden. <br />Consumptive use of water will be as dust suppression on the stockpiles and <br />working face. The amount required for dust suppression is expected. to be less than <br />2000 gallons per year due to the low volume of production. The water will be <br />purchased from an appropriate water source and distributed with a water truck as <br />needed. <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 />Revised January 5, 2011 <br />Page 10 of 24
