CWQCC lists numeric standards for Segment 136 in its <br /> regulation 3.7.0. The permittee monitors water in [he Williams <br />L. Instream CWQCC Fork River at a site upstream from :Eagle's mining (WF-1), and <br />Numeric regulation es a site downstream from mining (W:F-2). Data from the upstream <br />Standards 3.3.0 y site indicate the Williams Fork River naturally exceeds the iron <br /> numeric standard frequently, and the lead and manganese <br /> standards occasionally. Comparison of the upstream and <br /> downstream data indicate mining and reclamation operations at <br /> the Eagle Mines do no[ cause [he numeric standards to be <br /> exceeded. <br />M.
