be from the mine, so Whole E®uent Toxicity (W.E.T.) tests would be required when the <br />discharge contains water received from the mine. <br />In summary, MCC proposes combining three dischazges into one outfall, as these discharges are <br />currently physically combined (in a mutual spillway, culverts, piping, and ditches downstream of <br />the individual dischazges) prior to reaching the North Fork of the Gunnison River. As such, <br />sampling from only one outfall would be required. This would reduce the sampling redundancy <br />for each discharge point and reduce the escalating costs of water quality analyses, particularly <br />W.E.T. testing. MCC anticipates that the standard parameters of flow, pH, electrical conductivity, <br />total dissolved solids, total suspended solids, and 'von would continue to be applicable to this <br />new, combined discharge point. <br />Should you have any questions or need additional information concerning this amendment <br />request, please contact me at (970) 929-2238. <br />SI ~ j~~~'c'LV`C~ <br />A. be V <br />Environm al Coordinator <br />xc: D.
