WHAT IS A TMDL?

A Total Maximum Daily Load (TMDL) is the maximum amount of a pollutant a water body can receive and still meet water quality standards. A TMDL analysis is required by the U. S. Environmental Protection Agency for all impaired water bodies. The result of a TMDL is the load and wasteload allocations by pollutant source that must be met to achieve water quality standards and targets for a pollutant. That is, TMDLs establish the pollutant reductions needed from each pollutant source to meet water quality goals.

MMSD is developing TMDLs as a third party on behalf of the Wisconsin Department of Natural Resources for the Menomonee River, Kinnickinnic River, and Milwaukee River Watersheds, and for the Milwaukee Harbor Estuary. The pollutants of interest are fecal coliform bacteria, phosphorous, and sediment.

     

     

     

     

     

     

     

     

     

     

     

     

     

     

     

     

     

     

     

     

     

     

     

     

     

     

     

     

     

  2020/Water Quality Initiative

MMSD's 2020 Facilities Plan (2020 FP) identifies the facilities, programs, operational improvements, and policies (FPOPs) required by the year 2020 to meet the existing regulatory framework and permitting requirements.
