(yes <br /> /no <br /> The Eagle Mines are on Segment 136 of the Lower <br /> Yampa/Green River Sub-basin of the Lower Colorado River <br /> Basin. CWQCC lists numeric standards for Segment 13b in its <br /> regulation 3.7.0. The permittee monitors water in the Williams <br /> Fork River at a site upstream from Eagle's mining (WF-1), and <br /> a site downstream from mining (WF-2). Data from the upstream <br />L Instream CWQCC site indicate [he Williams Fork River naturally exceeds the iron <br />Numeric regulation yes numeric standard frequently, and the lead and manganese <br />Standards 3.3.0 standards occasionally. Comparison of the upstream and <br /> downstream data indicate mining and reclamation operations at <br /> the Eagle Mines do not cause the numeric standards to be <br /> exceeded. NPDES monitoring of mine pumping at outfalls 024 <br /> and 003 shows the quality and quantity of the pumped water <br /> would not cause an exceedance of Williams Fork River instream <br /> standards. <br />J.
