What is an illicit discharge?
Illicit discharge means any intentional discharge to the municipal storm sewer system that is not composed entirely of stormwater, except discharges pursuant to any National Pollutant Discharge Elimination System (NPDES) permit, or discharges resulting from fire fighting activities. Examples of illicit discharges are overflowing sanitary sewers, draining a swimming pool into the street, or dumping used motor oil into a storm drain.
