What is an illicit storm drain discharge?

An illicit discharge is any non-stormwater flow into the storm drain system or receiving waters, including untreated wastewater, industrial runoff, fuels, oils, sewage, and concentrated wash water. Even small, repeated releases can harm fish, contaminate recreational waters, and violate municipal and state water-quality rules.
