CWQCC lists numeric <br /> standards for Segment 13b in its regulation 3.7.0. <br /> The permittee monitors water in the Williams Fork <br /> River at a site upstream from Eagle's mining (WF- <br /> 1), and a site downstream from mining (WF-2). <br /> CWQCC Data from the upstream site indicate the Williams <br />I.

Compazison of the <br /> upstream and downstream data indicate mining <br /> and reclamation operations at the Eagle Mines do <br /> not cause the numeric standards to be exceeded. <br /> NPDES monitoring of mine pumping at outfalls <br /> 024 and 003 shows the quality and quantity of the <br /> pumped water would not cause an exceedance of <br /> Williams Fork River Instream standards. <br /> C WCC Eagle 5 and 9 are not subject to the <br />J.
