Complied with? Comment <br /> (yes / no) <br /> The Eagle Mines are on Segment 13b of the Lower <br /> Yampa/Green River Sub-basin of the Lower <br /> Colorado River Basin. CWQCC lists numeric <br /> standards for Segment 13b in its regulation 3.7.0. <br /> The perminee 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 /> Data from the upstream site indicate the Williams <br /> Fork River naturally exceeds the iron numeric <br /> yes standard frequently, and the lead and manganese <br /> standards occasionally. Comparison 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 /> Eagle 5 and 9 aze not subject to the <br /> Antidegradation Rule because the receiving waters <br /> yes (Segment 13b of [he Lower Yampa/Green River <br /> Sub-basin of the Lower Colorado River Basin) are <br /> desi nated "Use-Protected". <br /> yes <br />~irouna warer 41.~.G6 <br />L.
