NR 104.02 NoteNote: The application of this classification system is not dependent on the navigability properties of the watercourse, but is dependent upon the quantity-quality relationships of the surface water.
NR 104.02(2)(a)(a) Whenever the goals as specified in s. 283.001 (1) (b), Stats., cannot be attained because of conditions enumerated in s. NR 104.01 (1), a variance may be provided. Variances from a specific water quality criteria may be given in s. NR 104.05 et. seq. or a variance under one of the categories provided in this chapter may be specified. NR 104.02(2)(b)(b) Practices attributable to municipal, industrial, commercial, domestic, agricultural, land development, or other activities shall be controlled so that waters regardless of their hydrologic and water quality classifications meet the general aesthetic and acute toxicity conditions in s. NR 102.04 (1). NR 104.02(3)(a)(a) Limited forage fish communities (intermediate surface waters). NR 104.02(3)(a)1.1. ‘Applicability.’ This category of variance may be applied to either the continuous or noncontinuous stream hydrologic classification. NR 104.02(3)(a)2.2. ‘Surface water criteria.’ The following water quality criteria shall be met in all surface waters included in this variance category: NR 104.02(3)(a)2.d.d. All other substances shall meet the acute and chronic toxicity criteria for limited forage fish communities specified in or developed pursuant to ss. NR 105.05 and 105.06. NR 104.02(3)(a)3.a.a. The effluent limitations determined necessary to meet the surface water criteria listed above are enumerated in table 1. NR 104.02(3)(a)3.b.b. Unless otherwise specified in table 1 above, effluent limitations for sewage treatment works shall be as adopted in ch. NR 210. NR 104.02(3)(a)3.c.c. In addition to the effluent limitations enumerated in table 1, effluent limitations for these and any other substance necessary to protect assigned uses shall be met, including water quality based effluent limitations necessary to meet the criteria specified in or developed pursuant to ss. NR 105.05 and 105.06 for limited forage fish communities. NR 104.02(3)(b)(b) Limited aquatic life subcategory (marginal surface waters). NR 104.02(3)(b)1.1. ‘Applicability.’ This variance category may be applied to the continuous or noncontinuous stream hydrologic classification, except that it shall be applied to all surface waters classified as effluent channel, wetland or diffuse surface water. NR 104.02(3)(b)2.2. ‘Surface water criteria.’ The following surface water quality criteria shall be met in all surface waters included in this variance category: NR 104.02(3)(b)2.c.c. All other substances shall meet the acute and chronic toxicity criteria for the limited aquatic life subcategory specified in or developed pursuant to ss. NR 105.05 and 105.06. NR 104.02(3)(b)3.a.a. The effluent limitations determined necessary to meet the surface water criteria listed above are enumerated in table 2. NR 104.02(3)(b)3.b.b. Unless otherwise specified in table 2 above, effluent limitations for sewage treatment works shall be as adopted in ch. NR 210. NR 104.02(3)(b)3.c.c. In addition to the effluent limitations enumerated in table 2, effluent limitations for these and any other substance necessary to protect assigned uses shall be met, including water quality based limitations necessary to meet the criteria for limited aquatic life surface water specified in or developed pursuant to ss. NR 105.05 and 105.06. NR 104.02(4)(4) Other classifications and effluent criteria. NR 104.02(4)(a)(a) Surface waters significant to the environmental integrity of the state or region. Under all hydrologic categories, the department reserves the right to require other effluent limitations, including allocation of wasteloads for organic material, toxicants and chlorine residuals if it is determined that the specified surface water is important to the overall environmental integrity of the area. In waters identified as trout streams, located in scientific areas or wild and scenic areas, providing endangered species habitat or of high recreational potential, effluent criteria will be evaluated on a case-by-case basis. NR 104.02(4)(b)1.1. ‘Streams.’ Where flowing streams or rivers are specified to achieve fish and aquatic life criteria, wasteload allocation for organic material, toxicants and chlorine residuals shall determine effluent criteria necessary to achieve that standard.
