Notes:
The combined mine and river values are weiahted by flow. NFG river flow = 11.220 apm. Mine outflow = 1,000 am.
North Fork of the Gunnison River 2007 AHR are operational values.
The significant increase in Nickel content is based on the B -1 value of 0.5 mq /I that may be a flyer.
Based upon the above calculations, the mine discharge into the North Fork of the Gunnison River will not have a significant impact.
