Illicit Discharge 

Reporting Directory

An illicit discharge is defined as any discharge to the storm sewer system that is not composed entirely of stormwater, except for discharges allowed under an NPDES permit or waters used for firefighting operations.  An illicit connection is a physical connection to an MS4 that primarily conveys non-stormwater discharges other than uncontaminated groundwater into the MS4.

Report illicit discharges, connections, and illegal dumping into storm drains, streams and other water bodies to your community.  Links and phone numbers to GLRC communities are located here:
