Illicit Discharge Hotline
Onondaga County Stormwater Pollution Hotline
A "Stormwater Pollution Hotline" has been established for reporting illicit discharges to surface water collection systems within regulated Municipal Separate Storm Sewer Systems (MS4) in Onondaga County.
If you suspect someone has illicitly discharged contaminants such as chemicals, construction materials, paint, or petroleum products to a storm sewer or roadway, please contact the Onondaga County Stormwater Pollution Hotline at 435-3157. The hotline is manned 24-hours a day, seven days a week.
What is an Illicit Discharge?
Illicit discharges are generally any discharges into a storm drain system that are not composed entirely of stormwater. Illicit discharges are a problem because, unlike wastewater which flows to a wastewater treatment plant, stormwater generally flows to waterways without any additional treatment. Illicit discharges often include pathogens, nutrients, and various toxic pollutants.
Illicit discharges enter the system through either direct connections (i.e. wastewater piping either mistakenly or deliberately connected to the storm drain) or indirect connections (i.e. infiltration into the MS4 from cracked sanitary systems, spills collected by drain outlets, or paint or used oil dumped directly into a drain). Pollutant levels from illicit discharges have been shown in EPA studies to be high enough to significantly degrade receiving water quality and threaten aquatic, wildlife, and human health."
Sources of Illicit Discharges:
- Sanitary wastewater
- Effluent from septic tanks
- Improper oil disposal
- Radiator flushing disposal
- Laundry wastewaters
- Spills from roadway accidents
- Improper disposal of auto and Household toxics
Not all non-storm water discharges are considered illicit discharges. Examples of discharges not subject to enforcement actions include:
- Fire fighting activities and water line flushing
- Landscape irrigation and lawn watering
- Diverted stream flows
- Rising ground waters
- Uncontaminated ground water (infiltration or pumped)
- Discharges from potable water sources
- Foundation and footing drains
- Air conditioning condensation
- Water from crawl space pumps
- Individual residential car washing
- Flows from riparian habitats and wetlands
- Dechlorinated swimming pool discharges
- Street wash water.
