A list of Wisconsin impaired waterbodies may be found on the department website at: https://dnr.wisconsin.gov/topic/SurfaceWater/ConditionLists.html
US EPA-approved TMDL.
If the permittee is subject to a US EPA-approved TMDL, the permittee shall evaluate its compliance with the applicable wasteload allocation consistent with the assumptions and requirements outlined in the TMDL. If the permittee cannot demonstrate compliance with the wasteload allocation within the first permit term, then the department may allow a permittee to develop a TMDL implementation plan that extends beyond one permit term for attaining the wasteload allocation. The implementation plan shall include estimated cost, schedules, assumptions, and levels of anticipated pollution control for each action. The TMDL implementation plan shall demonstrate continued progress leading to the attainment of the wasteload allocation as soon as possible. The department may establish numeric and narrative benchmarks within each permit term to ensure continued reduction of the pollutant of concern. In determining the length of time allowed under the TMDL implementation plan, the department shall consider all of the following factors:
Whether there is a need for the installation of both structural best management practices and the implementation of operation and maintenance programs to attain the wasteload allocation, and if so, how long it will take to implement taking into account factors including the need to acquire property, the need to remove or replace existing infrastructure, and the ability to obtain the necessary financing.
The length of time the permittee has had to attain the wasteload allocation under prior permits.
The extent to which the permittee has made good faith efforts to attain the wasteload allocation and other requirements in prior permits, if applicable.
The extent to which existing best management practices have proven to be effective in addressing the pollutant of concern covered by the wasteload allocation.
Whether the TMDL implementation plan is appropriate and necessary because the permittee cannot attain the wasteload load allocations within the existing permit term.
A permittee shall conduct an assessment of the actions required to be taken under this subsection. The assessment shall include a pollutant-loading analysis using an urban water quality model that uses small storm hydrology or equivalent methodology that is approved by the department, or monitoring, trend analysis, or other appropriate qualitative or quantitative evaluation methods approved by the department. At a minimum, a pollutant-loading analysis shall be conducted for total suspended solids, phosphorus, any applicable pollutants of concern covered under an applicable US EPA-approved TMDL, and pollutants of concern discharged by the permittee to a listed impaired waterbody, ERW, or ORW.
NR 216.07 Note
The department believes that computer modeling provides an efficient and cost-effective method for calculating pollutant loads. Pollutant loading models such as WinSLAMM, P8, or equivalent methodology may be used to evaluate the efficiency of the design in reducing total suspended solids. Information on how to access WinSLAMM and P8 is available at https://dnr.wi.gov/topic/stormwater/standards/slamm.html
