Project Detail

Develop Multiple TMDLs for the Milwaukee Estuary AOC

Purpose

The Milwaukee Metropolitan Sewerage District proposes to develop third-party pathogen, phosphorus, and sediment TMDLs for the Milwaukee Estuary in Southeastern Wisconsin. The TMDLS will result in pollutant load and wasteload allocations that must be met to meet water quality standards and targets and in implementation plans that will identify the steps needed to achieve the load and wasteload allocations.

Objective

This projects scope of work will be to develop a third-party TMDL for each of these watersheds. This will be done by performing water quality computer modeling of the watersheds to determine the quantity and quality of pollutants reaching the receiving waterbody. The results of the third-party TMDLs will be the load allocations and waste load allocations by pollutant source that must be met to meet the watersheds water quality standards for that pollutant. Additionally, implementation plans will be developed to identify the steps needed to reach the load allocations and waste load allocations. The work product from this effort will be unique to the watersheds but the implementation plans for this work will be carried out by/for all of the pollutant sources. No permits are required to perform this work.

Outcome

This project will address the following beneficial use impairments: degradation of fish and wildlife populations; eutrophication or undesirable algae; beach closings; degradiation of phytoplankton and zooplankton populations; degradation of aesthetics; and loss of fish and wildlife habitat.
