1. Counties are mandated by statute to administer and enforce Part 91. Each County will have a County Enforcing Agency (CEA), whose responsibility it is to review soil erosion and sedimentation control plans, issue permits, and take enforcement actions when necessary to ensure compliance with Part 91.

2. Some cities, villages, charter townships, and some general law townships have elected to enforce Part 91 through adoption of a soil erosion and sedimentation control ordinance. These agencies are called Municipal Enforcing Agencies (MEAs).  MEAs will  review soil erosion and sedimentation control plans, issue permits, and take enforcement actions when necessary to ensure compliance with Part 91 within their jurisdiction. 

3. Authorized Public Agencies (APAs) are state, county, or municipal agencies, such as the Michigan Department of Transportation, county road commissions, and city street departments, that have been designated by the DEQ to undertake earth change activities without having to obtain soil erosion and sedimentation control permits from the county or municipal enforcing agencies.  APAs can not issue SESC permits.

4. The DEQ, Water Resource Division (WRD) has oversight responsibility over all Part 91 agencies.
