(a) Agriculture; (b) Protection and propagation of fish and wildlife; (c) Industry; (d) Human consumption; (e) Recreation;
(f) Scenic value;
and, to achieve the goal of the federal act, which is to achieve, wherever attainable, surface water quality which provides for the protection and propagation of fish, shellfish, wildlife, and recreation in and on the water.
Section 4. Surface Water Classes and Uses. There are four classes of surface water in Wyoming (see Appendix A for listing):
(a) Class 1 - Those surface waters in which no further water quality degradation by point source discharges other than from dams will be allowed. Nonpoint sources of pollution shall be controlled through implementation of appropriate best management practices. In designating Class 1 waters, the Environmental Quality Council shall consider water quality, aesthetic, scenic, recreational, ecological, agricultural, botanical, zoological, municipal, industrial, historical, geological, cultural, archaeological, fish and wildlife, the presence of significant quantities of developable water and other values of present and future benefit to the people.
(b) Class 2 - Those surface waters, other than those classified as Class 1, which are determined to:
(i) Be presently supporting game fish; or
(ii) Have the hydrologic and natural water quality potential to support game fish; or
(iii) Include nursery areas or food sources for game fish.
(c) Class 3 - Those surface waters, other than those classified as Class 1, which are determined to:
(i) Be presently supporting nongame fish only; or
(ii) Have the hydrologic and natural water quality potential to support nongame fish only; or
(iii) Include nursery areas or food sources for nongame fish only.
(d) Class 4 - Those surface waters, other than those classified as Class 1, which are determined to not have the hydrologic or natural water quality potential to support fish and include all intermittent and ephemeral streams. Class 4 waters shall receive protection for agriculture uses and wildlife watering.
(e) Prior to proposing any changes in water classifications, the Department of Environmental Quality shall notify in writing local water users including the water commissioner, soil conservation committee, irrigation districts, county commissioners, and county ASCS. In addition, the Department of Environmental Quality shall notify in writing the Wyoming State Engineer, the Wyoming Water Development Commission, and the Wyoming Game and Fish Department.
All Class 1 and 2 waters are designated as coldwater game fisheries unless identified as a warmwater game fishery by a 'ww' notation in Appendix A.
Section 5. Standards Enforcement. The numerical and narrative standards contained within these regulations shall be used to establish effluent limitations for those discharges requiring control via permits to discharge in the case of point sources and best management practices in the case of nonpoint sources. If no permit or best management practice has been issued or implemented for a pollution source the state may, in addition to other appropriate legal action, take direct action to enforce these standards.
The processes used to implement the standards are described in various implementation documents adopted by the department. Such documents are adopted with full public participation and include, but are not limited to, the antidegradation policy, the Wyoming Continuing Planning Process (CPP), the wasteload allocation manual, best management practices, and the toxics control strategy.
Compliance with the conditions of these regulations does not exempt any discharger from the penalty provisions of W.S. 35-11-901.
Section 6. Interstate Compacts, Court Decrees and Water Rights. The department shall, after review and conference with the State Engineer, make recommendations to the State Engineer concerning proposed new diversions which could cause violations of these regulations.
(a) Except as authorized in paragraph (b), no new point sources other than dams, may discharge, and no existing point sources, other than dams, may increase their quantity of pollution discharge, to any water designated as Class 1.
(b) Storm water and construction-related discharges of pollution to Class 1 waters may be authorized and shall be controlled through applicable water quality permits, Section 401 certifications and/or by the application of best management practices. Such discharges shall not degrade the quality of any Class 1 water below its existing quality or adversely affect any existing use of the water. Temporary increases in turbidity that are within the limits established in Section 23 and that do not negatively affect existing uses can be permitted. For purposes of this section, temporary increases in turbidity shall not exceed the actual construction period. The Department shall impose whatever controls and monitoring are necessary on point source discharges to Class 1 waters and their tributaries to ensure that the existing quality and uses of the Class 1 water are protected and maintained.
(c) Nonpoint source discharges of pollution to Class 1 waters or tributaries of Class 1 waters shall be controlled by application of best management practices adopted in accordance with the Wyoming continuing planning process. For Class 1 waters, best management practices will maintain existing quality and water uses.
Section 8. Antidegradation. Water uses in existence on June 27, 1979 and the level of water quality necessary to protect those uses shall be maintained and protected. Those surface waters not designated as Class 1, but whose quality is better than these standards, shall be maintained at that higher quality. However, after full intergovernmental coordination and public participation the Wyoming Department of Environmental Quality may issue a permit for or allow any project or development which would constitute a new source of pollution, or an increased source of pollution, to these waters as long as the following conditions are met:
(a) The quality is not lowered below these standards;
(b) All existing water uses are fully maintained and protected;
(c) The highest statutory and regulatory requirements for all new and existing point sources and all cost effective and reasonable best management practices for nonpoint sources have been achieved; and
(d) The lowered water quality is necessary to accommodate important economic or social development in the area in which the waters are located.
Section 9. Mixing Zones. Except for Sections 14, 15, 16, 17 and 28 of these regulations, compliance with water quality standards shall be determined after allowing reasonable time for mixing. Except for the zone of initial dilution, which is the initial 10% of the mixing zone, the mixing zone shall not contain pollutant concentrations that exceed the acute aquatic life values (see Appendix B). In addition, there shall be a zone of passage around the mixing zone which shall not contain pollutant concentrations that exceed the chronic aquatic life values (see Appendix B).
Section 10. Testing Procedures. For determination of the parameters involved in the standards, analyses will be in accord with test procedures defined pursuant to: Title 40, Code of Federal Regulations, Part 136, or any modifications thereto. For test procedures not listed in the Code of Federal Regulations, test procedures outlined in the latest editions of: EPA Methods for Chemical Analysis of Water and Wastes; or, Standard Methods for the Examination of Water and Wastewaters; or, ASTM Standards, Part 31, Water shall be used.
The analytical technique for total uranium (as U) shall be the fluorometric method as referenced in Methods for Determination of Radioactive Substances in Water and Fluvial Sediments, Techniques of Water - Resource Investigations of the U.S. Geological Survey, Book 5, Chapter A-5, pp. 83 - 92.
Where standard methods of testing have not been established, the suitability of testing procedures shall be determined by the department and the EPA using defensible scientific methods.
(a) Water quality standards shall apply at all times except during periods of low flow. Low flow can be determined by: 1) using the 7Q10 (the minimum 7 consecutive day flow which has the probability of occurring once in 10 years) for acute exposures, 2) the EPA's biologically based flow method which determines a 4 day, 3 year low flow for chronic exposures and a 1 day, 3 year low flow for acute exposures (ref: Technical Guidance Manual For Performing Waste Load Allocation: Book VI, Design Conditions: Chapter 1, Stream Design Flow for Steady-State Modeling, August 1986, US EPA), or 3) other defensible scientific methods. Whatever method is selected for a specific situation, application of the standards will conform to the magnitude, frequency, and duration provisions as described in these standards.
(b) During periods when stream flows are less than the minimums described above, the department may, in consultation with the Wyoming Game and Fish Department, require dischargers to institute operational modifications as necessary to insure the protection of aquatic life.
(c) Sections 14, 15, 16, 17, and 28 shall apply at all stream-flow conditions.
Point or nonpoint sources of pollution shall not cause the destruction, damage, or impairment of naturally occurring wetlands except when mitigated through an authorized wetlands mitigation process. However, this section does not apply to wetlands created by point or nonpoint sources; nor are such wetlands required to be maintained through continuation of such discharges.
Except for those substances referenced in Sections 21 (e) and (f), toxic materials attributable to or influenced by the activities of man shall not be present in any Wyoming surface water in concentrations or combinations which constitute "Pollution" as that term is defined in W.S. 35-11-103 (C) (i).
Section 14. Dead Animals and Solid Waste. In no case shall dead animals of any description be placed or allowed to remain in Wyoming surface waters or be placed or allowed to remain in any location which would result in contamination or threaten contamination of Wyoming surface water.
Except as authorized through a "404 permit", solid waste shall not be placed or allowed to remain in surface waters of the state, nor shall solid wastes be placed or allowed to remain in any location which would cause or threaten contamination of Wyoming surface waters.
Section 15. Settleable Solids. In all Wyoming surface waters, substances attributable to or influenced by the activities of man that will settle to form sludge, bank or bottom deposits shall not be present in quantities which could result in significant aesthetic degradation, significant degradation of habitat for aquatic life or adversely affect public water supplies, agricultural or industrial water use, plant life or wildlife.
Section 16. Floating and Suspended Solids.

In certain waters, the criteria listed in Appendix B may not be appropriate due to unique physical or chemical conditions. In such cases, human health values may be determined by use of the site-specific procedures outlined in the references listed in Appendix E.
Section 19. Industrial Water Supply. All Wyoming surface waters which have the natural water quality potential for use as an industrial water supply shall be maintained at a quality which allows continued use of such waters for industrial purposes.
Degradation of such waters shall not be of such an extent to cause a measurable increase in raw water treatment costs to the industrial user(s).
Unless otherwise demonstrated, all Wyoming surface waters have the natural water quality potential for use as an industrial water supply.
Section 20. Agricultural Water Supply. All Wyoming surface waters which have the natural water quality potential for use as an agricultural water supply shall be maintained at a quality which allows continued use of such waters for agricultural purposes.
Degradation of such waters shall not be of such an extent to cause a measurable decrease in crop or livestock production.
Unless otherwise demonstrated, all Wyoming surface waters have the natural water quality potential for use as an agricultural water supply.
(a) Ammonia - The toxicity of ammonia varies with pH and temperature and the applicable limitations are included in the charts in Appendix C.
(b) Specific numeric standards for a number of toxicants are listed in the aquatic life 'acute value' and 'chronic value' columns in Appendix B. These standards apply to all Class 1, 2, and 3 waters. For these pollutants, the chronic value (four day average concentration) and the acute value (one hour average concentration) shall not be exceeded more than once every three years.
(c) Others - For those pollutants not listed in Appendix B or C, maximum allowable concentrations shall be determined through the bioassay procedures outlined in the references listed in Appendix E.

Section 28. Undesirable Aquatic Life. All Wyoming surface waters shall be free from substances and conditions or combinations thereof which are attributable to municipal, industrial or other dischargers or agricultural practices, in concentrations which produce undesirable aquatic life.
Section 29. Oil and Grease. In all Wyoming surface waters, substances attributable to or influenced by the activities of man shall not be present in amounts which would cause: The oil and grease content to exceed 10 mg/l; or formation of a visible sheen; or visible deposits on the bottom or shoreline; or, damage or impairment of the normal growth, function or reproduction of human, animal, plant or aquatic life.
Section 30. Total Dissolved Gases. In all Class 1, 2 and 3 waters, the total dissolved gas concentration below man-made dams shall not exceed 110 percent of the saturation value for gases at the existing atmospheric and hydrostatic pressures.
Section 31. Salinity. The State of Wyoming is a member of the Colorado River Basin Salinity Control Forum, which includes all states in the Colorado River Basin. This forum has adopted a salinity control program for the basin which has been adopted as Chapter 6 of the Wyoming Water Quality Rules and Regulations.
Waters are listed within each drainage in upstream order. An indented entry is tributary to the previous entry.
All surface waters located within the boundaries of national parks and congressionally designated wilderness areas are Class 1 waters. Such Class 1 designation always takes precedence over the classification given in the listing. For example, Dinwoody Creek is shown as a Class 2 water; however, the upper portions are within a wilderness area and those portions are Class 1. The portion below the wilderness boundary is Class 2.
Except for waters in wilderness areas and waters listed in this Appendix, all waters within the boundaries of national forests are designated as Class 2.
All surface waters located within the Great Divide Basin are designated as Class 4.
The waters listed are all waters which are named on the USGS 1:500,000 hydrologic map of Wyoming and those previously classified by the department. Unless there is other information available, any unlisted water shall have the same classification as the first listed water to which it is a tributary.
All Class 1 and 2 waters are designated as coldwater game fisheries unless identified with a 'ww' notation.

values for metals, the values refer to the acid soluble portion which is derived as the fraction that passes through a .45 μm membrane filter after the sample is acidified to pH 1.5-2.0 with nitric acid.
(2) Based on two routes of exposure - Ingestion of contaminated aquatic organisms and drinking water.
(3) Substance classified as a carcinogen with the value based on an incremental risk of one additional instance of cancer in one million persons.
(4) Hardness dependent criteria. Value given is an example only and is based on a CaCO₃ hardness of 100 mg/l. Criteria for each case must be calculated using the formula in Appendix F.
(5) pH dependent criteria. Value given is an example only and is based on a pH of 7.8. Criteria for each case must be calculated using the formula in Appendix G.
(6) Chemicals which are not individually classified as carcinogens but which are contained within a class of chemicals with carcinogenicity as the basis for the criteria derivation for that class of chemicals; an individual carcinogenicity assessment for these chemicals is pending.
(7) Value is based on organoleptic (taste and odor) effects and is more stringent than if based solely on toxic or carcinogenic effects.
(8) EPA Section 304(a) human health criteria recommendation assuming consumption of contaminated aquatic organisms at a rate of 6.5 grams per day.
(9) The criterion is based on an EPA drinking water standard (Maximum Contaminant Level or MCL).
(10) The chronic aquatic life value for mercury (0.012) represents the Total Recoverable amount. This value cannot be converted to dissolved.
(11) The iron and manganese criteria are based on Safe Drinking Water Act secondary standards and are intended to prevent undesirable aesthetic effects. These values represent the dissolved amount of each substance rather than the total amount.
(12) Value is based on the dissolved amount which is the amount that will pass through a 0.45 μm membrane filter prior to acidification to pH 1.5-2.0 with nitric acid.
(13) Aquatic life values for manganese apply only on Class 2 waters where the numeric human health criterion does not apply. These waters are listed in Appendix B - Site Specific Criteria.
The criteria in this section is applicable only to the waters and/or locations specified and replaces similar criteria expressed elsewhere in Chapter 1.
The numeric human health criteria for iron and manganese shall not apply to Class 2 waters in the Belle Fourche River Drainage above the confluence of Donkey Creek and the main stem of the Belle Fourche River (including Donkey Creek);
The numeric human health criteria for iron and manganese shall not apply to main stem of the Belle Fourche River below the confluence of Donkey Creek.
The numeric human health criteria for iron and manganese shall not apply to Antelope Creek and all of its Class 2 tributaries;
The numeric human health criteria for iron and manganese shall not apply to Little Thunder Creek and all of its Class 2 tributaries below the confluence of North Prong.
The numeric human health criteria for iron and manganese shall not apply to Class 2 waters in the Little Powder River Drainage.
The numeric human health criteria for iron and manganese shall not apply to Class 2 waters in the Powder River Drainage except on the following waters:
The main stem of Clear Creek and its Class 2 tributaries upstream of Clearmont, Wyoming;
The main stem of Crazy Woman Creek and its Class 2 tributaries;
The North Fork of the Powder River and all its Class 2 tributaries; and
The Middle Fork of the Powder River and all its Class 2 tributaries.
