• <br />2.05.6 Mitigation of the Impacts of Mining Operations <br />A better indicator of the quality of water in the Cameo seam is the quality <br />of water discharged from the McClane Canyon Mine which is mining in the <br />same seam approximately four miles south of the Red Cliff Mine. <br />McClane Canyon Mine's discharge monitoring reports from 2002 to 2007 <br />show Electrical Conductance (EC) values ranging from 1,798 to 2030 with <br />a average of 1918 umhos/cm, TDS values ranged from 705 to 3250 with <br />and average of 1814 mg/I and pH ranged from 7.3 to 8.7 with an average <br />of 8.1. Based on the analysis of mine discharge presented in Volume III, <br />Exhibit 3, iron concentrations ranged from <0.01 to 0.07. Manganese <br />concentrations ranged from <0.01 to 0.057. <br />Based on the predicted quality of the mine water discussed above, mine <br />water seepage into the upper or lower perched water bear zones would <br />improve the water quality in both zones. <br />• <br />• <br />Permit Application <br />2.05-105 06/08
