MI — Stormwater Compliance
Michigan Construction
Stormwater Inspections
Michigan uses a unique dual-permitting approach through EGLE, requiring both a Part 91 Soil Erosion and Sedimentation Control permit and NPDES stormwater authorization. Sites disturbing 1-5 acres receive automatic coverage under Permit-by-Rule, while sites of 5+ acres require a separate NPDES application. Michigan's extensive Great Lakes shoreline and inland waterways demand rigorous construction stormwater management.
