Full Breakdown

Under MCL 324.9101 et seq., any earth change disturbing one or more acres or occurring within 500 feet of a lake or stream requires a soil-erosion permit issued by the local enforcing agency under state delegation. EGLE oversees county and municipal enforcement programs, sets minimum BMP standards, and can revoke local authority for non-performance. Permits must be obtained before earth-moving activity begins.

Violations & Penalties

Violations are civil infractions with fines up to $2,500 per day; willful violations may be misdemeanors.

Frequently Asked Questions

Does Part 91 apply to single-family home construction?

Single-family homes on lots smaller than one acre and outside the 500-foot waterway buffer are exempt, but local ordinances may still require sediment control plans.

Who issues the soil erosion permit?

Permits are issued by the county or municipal enforcing agency authorized by EGLE. Some counties delegate to townships; check with the local public works office.
