All other sections of the current permit <br />remain unchanged. <br />Exhibit B / Site Description: <br />The permitted area would expand to the south by 1.280 acres for a total of 9.958 acres. <br />A wash plant, water pump, and recirculation- settling pond would be located in the north end of <br />the permitted area. <br />Exhibit C / Mining Plan: <br />See Exhibit E — Mining Plan Map <br />Add gravel washing operations. Water rights for this operation were acquired on 23 October <br />2012 in the District Court, Water Division 4 under Case Number 12CW36. <br />The material to be washed is estimated to be 10,000 tons annually. Wash water would be initially <br />taken from the Uncompahgre River into a 70,000 -f1 (1.61 acre -foot) recirculation - settling pond. <br />The pond dimensions will be approximately 100 ft by 100 ft by 10 ft deep with a 2:1 inside slope <br />(average depth 7 ft). The owner /operator will need to form a protective berm between the river <br />and pond to mitigate damage to the pond and any gravel crushing or washing equipment. <br />The pond will be lined with a 24 -mil (0.61mm) liner designed for long -term, non - hazardous use. <br />Water from the pond will then be used to wash gravel product with the effluent from the wash <br />plan returning to the pond for reuse. No soaps or chemicals will be used to <br />wash product. The pond would be recharged as necessary from the river. <br />
