What counts as an illicit storm drain discharge

An illicit discharge is any discharge to the municipal separate storm sewer system (MS4) that is not composed entirely of stormwater, except as permitted by law. Typical examples include sanitary sewage leaks, motor oil or fuel, industrial washwater, and concentrated construction runoff. If you see colored liquids, oily sheens, persistent foam, or strong odors entering a curb inlet, these may be illicit discharges.

Report visible spills immediately to limit environmental harm.

How to report a suspected illicit discharge

Report concerns through the City of Grand Rapids service request system or contact Public Works/Stormwater staff. Provide location (nearest address or inlet), observed materials, time and duration, photos if safe to take, and any witness contact information. Use the city reporting portal or call the stormwater contact to file a complaint.Report a concern[2]
