• Comment <br />3-10 - Report stated that seepage from the earthen dams was checked <br />by testing Ralston Creek water from paints opposite each <br />pond. These do not appear to be satisfactory sampling points <br />to check the seepage. Monitoring wells are planned to be <br />drilled to check for seepage from the ponds. <br />Response <br />This pertains to the NP DES permit which is outside of the <br />scope of this application. <br />Comment <br />3-14 - The Colorado Department of Health Air Pollution Control <br />Division should evaluate the air pollution aspects. <br />Response <br />An emissions permit for the ore sorter was issued by the AP(:D <br />on March 22, 1979. <br />Comment <br />• 6-1 - More detailed information is needed concerning decontamina- <br />tion and disposal of waste material and equipment which is See Sec. 6.1 <br />shipped to the mill. Capacity of the tailing ponds and <br />method of disposal at the mill site should be included in <br />the application. <br />Response <br />There will be approximately 1200 tons of waste. This is thEa <br />equivalent of 3 days' output from the mine and can be easily <br />accommodated by the mill. The tailings impoundment has a <br />design volume of 7,550 acre feet. <br />Comunent <br />As mining progresses and more mine water is discharged, <br />what are the plans for handling this increased volume of <br />water? <br />Response <br />No response necessary, as it pertains to the discharge permit <br />for the mine. The assumption that more mine water will be <br />produced as mining progresses is invalid; no significant <br />• change in the water volume discharged into Ralston Creek is <br />anticipated for the remaining mine life. <br />JC-3 <br />
