Illicit Discharge

Illicit discharge is any discharge to the Municipal Separate Stormwater Sewer System (MS4) that is not composed entirely of stormwater except discharges pursuant to a National Pollutant Discharge Elimination System (NPDES) permit (other than the NPDES permit for discharges from the MS4) and discharges from fire fighting and emergency management activities. Other exceptions are listed in the Stormwater Ordinance.
