Support the development and implementation of approved Watershed Management Plans in the Michigan’s portion of the Western Lake Erie Basin

The Michigan Department of Environmental Quality will support the development and implementation of approved watershed management plans (WMPs) in Michigan’s portion of the Maumee River watershed and Michigan's watersheds that discharge directly into western Lake Erie.

Identify priority areas and actions in Michigan’s portion of the Maumee River Watershed for phosphorus reductions

Only a small portion (about 7 percent) of the Maumee watershed lies within Michigan’s borders. Michigan is partnering with Indiana, Ohio, the U.S. EPA, and the U.S. Geological Survey to ensure appropriate monitoring of the watershed. Though continued monitoring is needed, initial monitoring and analysis has revealed that certain parts of the Maumee watershed in Michigan have higher phosphorus concentrations than others.

Achieve and maintain phosphorus reductions at four key wastewater treatment facilities

There are four wastewater treatment plants (WWTPs) that will be addressed in the Michigan DAP, including the Great Lakes Water Authority Detroit Wastewater Recovery Facility, the Wayne County Downriver Wastewater Treatment Facility (WTF), the Ypsilanti Community Utilities Authority (YCUA) WWTP, and the Monroe Metro WTF. These facilities discharge over 90 percent of the total phosphorus point source load downstream of the beginning of the Detroit River to Lake Erie.
