NR 212Subchapter III — Development of Total Maximum Daily Loads and Effluent Limitations Developed Through Wasteload Allocations NR 212.71NR 212.71 Applicability. This subchapter establishes the procedures, methodologies, and requirements to be used for determining total maximum daily loads and water quality-based effluent limitations developed through wasteload allocations for pollutants except as provided in subch. II. NR 212.71 HistoryHistory: CR 15-085: cr. Register August 2016 No. 728, eff. 9-1-16. NR 212.72NR 212.72 Definitions. In addition to the definitions and abbreviations in ss. NR 205.03 and 205.04 the following definitions are applicable to the terms of this subchapter: NR 212.72(1)(1) “EPA” means the United States environmental protection agency. NR 212.72(3)(3) “Increased discharge” means any increase in the concentration or mass loading of a pollutant of concern that exceeds an effluent limitation that is in effect in a current permit. NR 212.72(5)(5) “Loading capacity” means the greatest amount of loading that a water can receive without violating water quality standards. NR 212.72(6)(6) “Margin of safety” means a required component of the TMDL that accounts for the uncertainty in the response of the waterbody to loading reductions. NR 212.72(7)(7) “Natural background load” means loads emanating from natural sources, including but not limited to forested and undeveloped lands and from natural processes such as weathering and dissolution, which would exist in the absence of measurable impacts from human activity or influence. NR 212.72(8)(8) “New discharge” means a point source that discharges the pollutant of concern that commenced operation after the TMDL was approved by EPA and was not given a wasteload allocation in the TMDL. NR 212.72(9)(9) “Pollutant of concern” means any pollutant discharged that has an applicable TBEL, a wasteload allocation from a TMDL or watershed analysis, or is identified as needing a WQBEL to meet water quality standards. NR 212.72(10)(10) “TBEL” means technology-based effluent limitation. NR 212.72(11)(11) “TMDL” means total maximum daily load and is the sum of the individual wasteload allocations for point sources, load allocations for nonpoint sources, natural background, and a margin of safety. TMDLs can be expressed in terms of mass per time, toxicity, or other appropriate measures that relate to a state water quality standard. NR 212.72(13)(13) “WQBEL” means water quality-based effluent limitation. NR 212.72 HistoryHistory: CR 15-085: cr. Register August 2016 No. 728, eff. 9-1-16. NR 212.73NR 212.73 TMDL development requirements for impaired waters. NR 212.73(1)(1) Purpose. This section establishes the procedure, methodologies, and requirements to be used for developing TMDLs. NR 212.73(2)(2) Prioritization. The department shall create and maintain an impaired waters list of waters that fail to meet water quality standards and, therefore, require the development of TMDLs or alternative remediation plans. The impaired waters list shall include a priority ranking for the development of a TMDL for all listed waters. The priority ranking shall consider the severity of the pollution, the uses to be made of such waters, and whether implementing existing TBELs and WQBELs in permits are sufficient to achieve water quality standards. By April 1 of each even-numbered year, the Department shall submit to the EPA a prioritized ranking of waters on the impaired waters list targeted for TMDL development for a two-year period. Impaired waters addressed by alternative remediation plans may be assigned a low priority for TMDL development on the impaired waters list. NR 212.73 NoteNote: The impaired waters listing and priority setting process is specified in the Wisconsin Consolidated Assessment and Listing Methodology (WisCALM).
NR 212.73 NoteNote: Examples of remediation plans include, but are not limited to, lake protection and restoration plans, remedial action plans, environmental accountability projects, area-wide water quality management plans, adaptive management plans, and nine key element watershed plans.
NR 212.73(3)(a)(a) The department shall establish TMDLs for impaired waters in accordance with the prioritization in sub. (1). TMDLs shall be established at levels necessary to attain and maintain applicable numeric and narrative water quality standards with seasonal variations and a margin of safety that takes into account any lack of knowledge concerning the relationship between effluent limitations and water quality. TMDLs shall take into account critical conditions for stream flow, loading, and water quality parameters. NR 212.73(3)(b)(b) TMDLs shall be established to ensure attainment of all designated uses and applicable numeric and narrative water quality standards for the pollutant of concern including applicable numeric and narrative criteria under chs. NR 102 and 105. NR 212.73(3)(c)(c) TMDLs may be established using a pollutant-by-pollutant or biomonitoring approach. In many cases both techniques may be needed. Site specific information should be used whenever possible.
