<br />-3- <br />• Impacts <br />~~ <br />The following table shows the volume of water which was discharged to <br />North Thompson Creek from the No. 1 and No. 3 mines: <br />Total Mine Discharge 10/84 to 9/85 <br />No. 1 Mine <br />No. 3 Mine <br />Treatment Plant (Consumptive) <br />Washer Plant (Consumptive) <br />Dust Suppression (Consumptive) <br />Total Discharge <br />262.80 acre-feet <br />100.79 acre-feet <br />1.02 acre-feet <br />-0- <br />-0- <br />362.57 acre-feet <br />As can tie seen, most of the water being pumped from the mines is dis- <br />charged into North Thompson Creek. Because of the good quality of this dis- <br />charged water the impacts to the river and downstream user have been ben- <br />eficial. <br />Mine Water Quality <br />Appendix VI contains water quality data for the discharges from the No. 1 <br />and No. 3 mines. The water from these mines continues to show a lack of <br />• heavy metals. During the period between October, 1984 to September, 1985 <br />none of the NPDES levels for Oil and Grease, Total Iron, Dissolved Solids <br />or Suspended Solids were exceeded. <br />Anticipated Impacts <br />The future outlook for Snowmass is to continue as is for quite some <br />time. Therefore, no impacts to the hydrological balance in the North Thomp- <br />son Creek area are anticipated. <br /> <br />,, <br />
