MS4 Permits
Public entities in urbanized areas that own and operate a municipal separate stormwater system (MS4) must have a permit to discharge stormwater into Waters of the State. In Michigan, the state permitting authority is the Michigan Department of Environment, Great Lakes and Energy.
Several communities in the Macatawa Watershed are MS4 operators that must comply with stormwater permit requirements. They include the City of Holland, City of Zeeland, Ottawa County, Allegan County, the Ottawa County Road Commission, and the Allegan County Road Commission. These six entities work cooperatively with the MACC to maintain compliance with their stormwater permits.
One key component of the MS4 permit is to provide the public an opportunity to review and provide comments on the Stormwater Management Plan (SMP). The SMPs for the currently active permits are provided below.
The MACC provides compliance assistance to the six MS4 entities through a contract with the ODC Network. For questions about the MS4 permits, contact Kelly Goward, ODC Network Land & Water Director at kelly@outdoordiscovery.org

Stormwater BMP Operation and
Maintenance Planning
All new or redevelopment projects subject to site plan review are required to have a plan for how they will manage stormwater. An important component of any plan is to ensure proper operation and maintenance by proactively inspecting and maintaining the stormwater controls on site. In 2020, the MACC developed a Stormwater BMP Operation and Maintenance Planning Guide to assist developers in writing a plan. The guide and supplemental documents are provided below.
