Instream Numeric Standards for segments 2 and 6 are set forth in Rule 35 of CWQCD <br /> regulation 5 CCR 1002. Calculated Table Value Standards for instream metal concentrations are <br /> shown in Tables A-4 and A-5 of West Elk's discharge permit (CDPS permit CO-0038776). West <br /> Elk discharges surface runoff and/or mine water to segments 2 and 6 via CDPS outfalls. CWQCD <br /> based effluent limitations at these outfalls on values that would not cause exceedances of instream <br /> standards. West Elk's compliance with its effluent limitations in 2006 indicates the instream <br />G. Instream CWQCC standards probably were not exceeded as a result of surface water discharges.
