Minrec, Incorporated Water Quality Assessment CO- 0048233 <br />III. Water Quality Standards <br />Narrative Standards <br />Narrative Statewide Basic Standards have been developed in Section 31.11(1) of the regulations, and <br />apply to any pollutant of concern, even where there is no numeric standard for that pollutant. Waters of <br />the state shall be free from substances attributable to human - caused point source or nonpoint source <br />discharges in amounts, concentrations or combinations which: <br />for all surface waters except wetlands; <br />(i) can settle to form bottom deposits detrimental to the beneficial uses. Depositions are stream bottom <br />buildup of materials which include but are not limited to anaerobic sludge, mine slurry or tailings, silt, <br />or mud; or <br />(ii) form floating debris, scum, or other surface materials sufficient to harm existing beneficial uses; or <br />(iii) produce color, odor, or other conditions in such a degree as to create a nuisance or harm existing <br />beneficial uses or impart any undesirable taste to significant edible aquatic species or to the water; or <br />(iv) are harmful to the beneficial uses or toxic to humans, animals, plants, or aquatic life; or <br />(v) produce a predominance of undesirable aquatic life; or <br />(vi) cause a film on the surface or produce a deposit on shorelines; and <br />for surface waters in wetlands; <br />(i) produce color, odor, changes in pH, or other conditions in such a degree as to create a nuisance or <br />harm water quality dependent functions or impart any undesirable taste to significant edible aquatic <br />species of the wetland; or <br />(ii) are toxic to humans, animals, plants, or aquatic life of the wetland. <br />In order to protect the Basic Standards in waters of the state, effluent limitations and /or monitoring <br />requirements for any parameter of concern could be put in CDPS discharge permits. <br />Standards for Organic Parameters and Radionuclides <br />Radionuclides: Statewide Basic Standards have been developed in Section 31.11(2) and (3) of The <br />Basic Standards and Methodologies for Surface Water to protect the waters of the state from <br />radionuclides and organic chemicals. <br />In no case shall radioactive materials in surface waters be increased by any cause attributable to <br />municipal, industrial, or agricultural practices or discharges to as to exceed the following levels, unless <br />alternative site - specific standards have been adopted. Standards for radionuclides are shown in Table <br />A -2. <br />Table A -2 <br />Radionuclide Standards <br />Appendix A wQa v 7.0 Page 4 of 25 Last Revised Sept 14, 2009 /ES <br />
