The environmental quality of surface waters, consistent with uses applied in these standards, shall be maintained and protected. Hater quality degradation which would adversely affect existing uses will not be allowed. 2. State Resource Haters - Class A - These are surface waters which constitute an outstanding State or Nat- ional resource, such as waters within national or state parks, national forests or wildlife refuges, and waters of exceptional recreational or ecological significance. Haters which provide a unique habitat for federally designated endangered or threatened species and rivers designated under the Hild and Scenic Rivers Act are also included. The quality of these waters shall be maintained and protected. 3. State Resource Haters - Class B - These are surface waters which possess an existing quality which exceeds levels necessary to maintain recreational and/or aquatic life uses. The existing water quality of these surface waters shall be maintained and protected. However, the State may choose, in accordance with Neb. Rev. Stat. 81-1513 (Reissue 1981), to allow lower water quality as a result of important econoaic or social devel- opsefit. There shall be achieved the highest statutory and regulatory requirements for all new or existing point sources and all cost effective and reasonable best management practices for nonpoint source control. In cases where potential water quality impairment associated with a thermal discharge is involved, the method of Upleaentation of this antidegradation policy shall be consistent with Section 316 of the Clean Hater Act of 1977, 33 U.S.C. 1251 et seq. (the "Act'). 4, In iaplesenting this policy, the Department will follow the procedures outlined in the State's Continuing Planning Process. State Narrative Language For: Toxics Hastes or toxic substances introduced directly or indirectly by human activity in concentrations that would degrade the use shall not be allowed. Surface waters of the State shall be free from toxic substances in toxic amounts. No toxic substances alone or in coibination with other substances in concentrations rendering the receiving water unsafe or unsuitable for aquatic life will be allowed. (In iaplementing these criteria, the Department will follow procedures outlined in the State's Continuing Planning Process which comply with the federal water quality standards, 40 C.F.R. 131.11 (1986)). Surface waters shall be free of radionuclides or toxic substances in concentrations or combinations which may produce undesirable physiological responses in huians. State Narrative Language For: Free From No toxic substances alone or in combination with other substances in concentrations rendering the receiving water unsafe or unsuitable for aquatic life will be allowed. Haters shall be free from human induced pollution which cause: 1, noxious odors; 2. floating, suspended, colloidal, or settleable materials that produce objectionable films, colors, turbidity, or deposits; and NE-1 ------- NEBRASKA 3i the occurrence of undesirable or nuisance aquatic life. State Narrative Language For: Low Flow These standards, except criteria associated with aesthetics and public health (Chapter 4-005), will not apply to: . i. Waters during periods when the flow is less than 0.1 cfs or the 7-day, 10-year low flow, unless an assigned beneficial use still exists under these conditions. Flow conditions apply to rivers and streais and not to lakes and reservoirs. , 2. Effluent dotinated streets during periods when the daily flow is totally composed of effluent, excluding ainor aicunts of bank seepage. State Narrative Language For: Mixing Zones The Hater Quality Standards shall apply at and beyond the tixing zone boundaries. The tixing rone exception does not apply to fecal coliforai criteria in waters designated a priiary contact recreational use. The boundary liiits of the lixing zone shall be a specified linear distance, volute, or area, and should ieet the conditions listed below unless the physical characteristics of the receiving waters require special consider- ations. In the latter case the Departtent will establish iixing zones applicable to the physical characteris- tic of the receiving waters in such a tanner that will not affect the assigned beneficial uses. (a) The tixing zone should be kept as stall as possible and shall not be of a size or shape that would itpair or contribute to the itpainent of water use. (b) The eixing zone shall allow for a continuous zone of passage for aquatic life. (c) The iixing zone shall not overlap other tixing zones if beneficial uses are adversely affected. NE-2 ------- NEBRASKA Classifications Prisary Contact Recreation Class A / Secondary Contact Recreation Class 6 Coldwater Habitat Class A Coldwater Habitat Class B Harmwater Habitat Class A Narswater Habitat Class B Hater Supply Public Drinking Hater Agricultural Class A Agricultural Class B Industrial Aesthetics and Public Health Priaary contact recreation includes activities where the body lay coie into prolonged or intiiate contact with the Hater, such that water lay be accidentally ingested, it is not intended to be used as a potable water supply unless acceptable treatient is applied. These waters lay be used for swiiiing, water skiing, canoeing, and similar activities. Secondary contact recreation includes activities where the body usually does not coie into prolonged or intiiate contact with the water. It is very unlikely that the water will be ingested nor will sensitive body organs (e.g., eyes, ears, nose, etc.) be exposed. The waters may be used for fishing, hunting, and siiilar activities. These waters provide, or could provide, water quality and habitat conditions (e.g., flow, substrate, cover) which support a significant salionid (trout) population. All waters which support a naturally reproducing trout population are included. These are waters where coldwater aquatic life (including salionid populations) is liiited by natural water quality or habitat conditions. These waters will not support salionid spawning, but lay support a salionid population if periodically stocked. Haters which serve as seasonal pathways for salnonid . ligration are included. These waters provide, or could provide, water quality and habitat conditions (e.g. flow, substrate, cover) which maintain a wide variety of warmwater biota. These waters will support fish populations of recreational importance or populations of threatened species. These are waters where the potential variety of life fons is presently liiited fay degraded water quality (natural or irretrievable human-induced conditions) or habitat conditions. These waters will support fish populations consisting of nonsensitive forage species. These are surface waters which serve as a potable water supply. These waters iust be treated (e.g. coagulation, sedimentation, filtration, chlorination) before the water is suitable for huian consumption. After treatment, these waters are suitable for human domestic drinking water, food processing, and similar uses. These are waters used for general agricultural purposes (e.g. irrigation and livestock watering) without treatment. These are waters where the natural background water quality limits its use for agricultural purposes. These waters are potentially suitable for commercial or industrial use as cooling or processing (nonfood) water. Hater quality criteria necessary to protect this use will vary depending on the type of industrial process involved. Where actual uses are identified, site specific criteria will be developed to protect the use when necessary. This use applies to all surface waters of the state. To be aesthetically acceptable, waters shall be free from human induced pollution which causes: 1) noxious odor; 2) floating, suspended, colloidal, or settleable materials that NE-3 ------- NEBRASKA produce objectionable fills, colors, turbidity, or deposits; and 3) the occurence of undesirable nuisance aquatic life (e.g., algal bloots). Surface Ťaters shall be free of radionuclides or toxic substances in concentrations or coibinations which nay produce undesirable physiological responses in huians. Surface Maters shall also be free of junk.
