An augmentation plan will also be promptly filed for the water use. No mining <br />will take place below the water table until the substitution plan has been obtained or the site's <br />bond will be increased to cover the backfilling of the pit at the end of mining. <br />Due to the pit being neaz the City of Rifle water intake, a watershed permit issued by the City <br />of Rifle maybe needed. Issues involving this permit will be addressed prior to work beginning <br />in the pit. No wells other than the three Chambers' wells are located in the surrounding vicinity <br />which can be affected by the water drawdown from pumping. <br />11/7/2005 Page G2 <br />
