State Narrative Language For: Toxics Substances in concentrations or combinations which are toxic or harmful to humans shall not be present in aaounts found to be of public health significance, nor shall substances be present in amounts which are acutely harmful to aniial, plant or aquatic life. Unauthorized concentrations of substances are not permitted that alone or in combination with other materials present are toxic to fish or other aquatic life. The determination of the toxicity of a substance shall be based upon the available scientific data base. References to be used in determining the toxicity of a substance shall include, but not be United to: 1. 'Quality Criteria for Hater'. EPA-440/9-76-003. United States Environmental Protection Agency, Washington, DiC., 1976, and 2, "Water Quality Criteria 1972'. EPA-R3-73-033. National Academy of Sciences, National Academy of Engineering, United States Sovernient Printing Office, Washington, D.C., 1974. 3. Questions concerning the permissible levels, or changes in the same, of a'substance, or combination of substances, of undefined toxicity to fish and other biota shall be resolved in accordance with the methods specified in "Hater Quality Criteria 1972', "Standard Methods for the Examination of Water and Wastewater", 14th Edition, 1975 (American Public Health Association, New York) or other methods approved by the department of natural resources. The intake water supply will be such that by appropriate treatment and adequate safeguards it will meet the Public Health Service Drinking Water Standards, 1962, Concentrations of other constituents mist not be hazardous to health. State Narrative Language For: Free From Practices attributable to aunicipal, industrial, conercial, domestic, agricultural, land development or other activities shall be controlled so that all waters including the nixing zone and the effluent channel meet the following conditions at all times and under all flow conditions: A, Substances that will cause objectionable deposits, on the shore or in the bed of a body of water, shall not be present in such aeounts as to interfere with public rights in waters of the state. 8. Floating or subaerged debris, oil, scui or other material shall not be present in such amounts as to interfere with public rights in waters of the state. C. Materials producing color, odor, taste or unsightliness shall not be present in such amounts as to interfere with public rights in waters of the state. D, Substances in concentrations or conbinations which are toxic or harmful to humans shall not be present in aaounts found to be of public health significance, nor shall substances be present in amounts which are WI-1 ------- WISCONSIN acutely hanful to aniial, plant or aquatic life. State Narrative Language For: Low Flow Water quality standards Mill not be laintained under all natural occurrences of flow, teiperature or other Mater quality characteristics. The design of Mater quality related effluent liiitations or other aanageient: practices shall be based upon: a. The average tiniiut 7-day low streaa flow which occurs once in 10 years (7-day 010); or b. In the case of dissolved oxygen and wherever sufficient data on streai flow and teiperature are available, by application of a 0.274! level of nonattainient. This is equivalent to an expected nonattaintent of the dissolved oxygen criterion of one day per year. State Narrative Language For: Mixing Zones Hater quality standards lust be let at every point outside of a lixing zone. The size shall be based on such factors as effluent quality and quantity, available dilution, teiperature, current, type of outfall, channel configuration and restrictions to fish loveient. As a guide to the delineation of a lixing zone, the follow- ing shall be taken into consideration: (a) Liiiting lixing zones to as stall an area as practicable, and conforming to the tiie exposure responses of aquatic life. (b) Providing passageways in rivers for fish and other labile aquatic organists. (c) Where possible, lixing zones being no larger than 25 percent of the cross-sectional area or voluie of floH of the streai and not extending tore than 50 percent of the width. (d) For contaiinants other than heat, the 96-hour TLi to indigenous fish and fish food organists not being exceeded at any point in the lixing zone. (e) (fixing zones not exceeding 10 percent of a lake's total surface area. (f) Nixing zones not interfering with spawning or nursery areas, ligratory routes, nor louths of tributaries. (g) Mixing zones not overlapping, but where they do, taking measures to prevent adverse synergistic effects. (h) Restricting the pH to values greater than 4.0 s.u. and to values less than 11.0 s.u. at any point in the •ixing zone for the protection of indigenous fish and food organists. The theraal tixing zone provisions of this chapter are not applicable to lunicipal waste and water treatment plants, to vessels, or to discharges to enclosed harbors. Application of chenicals for water resource lanagetent purposes in accordance with statutory provisions is not subject to the requirements of the standards except in case of water used for public water supply.
