limitations occurred in the 2010 <br />water year. <br />Based on a Memorandum of <br />Understanding between the <br />Division of Reclamation, Mining <br />and Safety and the Water Quality <br />Control Division (WQCD), the <br />WQCD will be responsible for <br />enforcing CDPS permit conditions. <br /> The manganese standard was <br />8. Basic Standards for CWQCC regulations YES exceeded 23 times at eleven sites <br />Surface Water 31.1.11 including springs. Based on <br /> CWQCC reg. 31, the standard of <br /> 0.2 mg/I, applies to plants grown <br /> in acidic soils (<6.0 pH). In alkaline <br /> soils, as found on the PSCM site, <br /> the EPA standard would be 10 <br /> mg/I. The maximum manganese <br /> value observed at any surface site <br /> was 0.836 mg/I at NPDES 003. <br /> Spoil spring 6 exceeded the <br /> cadmium, nickel and manganese <br /> agricultural standards. The <br /> discharge of this spring flows into <br /> NPDES Pond 002, which did not <br /> exceed any of these parameters. <br />9. Instream Numeric CWQCC regulation 33.0 YES Two PSCM monitoring sites exist <br />Standards within the Fish Creek Drainage: <br /> The 004 outfall and SSC10 are on <br /> Cow Camp Creek and discharge <br /> into Fish Creek which is on <br /> Segment 13b of the Yampa River <br /> basin. The stream standards for <br /> Fish Creek are based on aquatic <br /> life standards. The sulfide <br /> standard (0.002 mg/I un-ionized) <br /> was exceeded at site 004 with a <br /> value of 0.0109 mg/I in <br /> September. <br /> Two PSCM monitoring sites exist <br /> within the Little Grassy Creek <br /> drainage: The 002 outfall and <br /> SSLGS. SSLG5 drains the upper <br /> portion of Little Grassy Creek <br /> which are undisturbed by mining.
