What is an Illicit Discharge?

An illicit discharge is anything other than stormwater. Pollutants that are intentionally dumped into stormwater are considered illicit and the polluter can be sited for a violation of the County Stormwater Ordinance if they are caught discharging in to the County Stormwater System.
Certain things are allowed. They are:
- Water line flushing
- Landscape irrigation
- Diverted stream flows or rising groundwater
- Infiltration of uncontaminated groundwater
- Public safety activities
- Pumping of uncontaminated groundwater from potable water sources, or foundation drains, irrigation waters, springs or water from crawl spaces or footing drains
- Air conditioning condensation
- Lawn watering
- Individual residential car washing
- Flows from riparian habitats or wetlands
- Dechlorinated swimming pool discharges
- Street flushing
- Those permitted by the State DEQ or DCR
