Wyoming, MI Environmental Rules: Erosion Control (2026)

Section 68-35 of the Stormwater Ordinance requires any person who causes, in whole or in part, an earth change in Wyoming, Michigan to provide soil erosion and sedimentation control adequate to keep soil from eroding onto adjacent properties or discharging into a stormwater drainage system, public right-of-way, wetland, creek, stream, water body or floodplain. The section lists specific duties during any earth change that exposes soil to erosion risk: obtain and comply with any required soil erosion and sedimentation control permit, protect public utilities and travel routes within the work area, prevent damage to nearby water bodies and adjoining land, and follow the approved plans and the city's Stormwater Standards Manual.

Track-out and spills must be addressed quickly. Removing soil, sediment or debris tracked onto streets or rights-of-way within 24 hours counts as prima facie compliance, unless the material poses an immediate hazard to public health and safety, in which case it must come off sooner. Grading near a property line cannot proceed without adequate support or other protective measures for adjoining land, streets or sidewalks. The property owner must have the erosion and sediment control measures inspected weekly and again within 24 hours of any rain event heavy enough to cause runoff; for sites of one acre or more, that inspection must be conducted by a construction site stormwater operator certified by Michigan's Department of Environment, Great Lakes, and Energy (EGLE), with written logs kept and made available to the city engineer on request.

This section works with Section 68-25, which requires any earth change on a regulated development site to get a soil erosion permit under NREPA Part 91 before work starts.
