An illicit discharge is any discharge to the storm sewer system that is not composed entirely of stormwater. A few exceptions to this rule include: firefighting activities, landscape irrigation, foundation drains, and water from crawl space pumps.
Sources of illicit discharge include but are not limited to:
• Sanitary wastewater
• Failing septic systems
• Improper oil disposal
• Radiator flushing disposal
• Spills from roadway accidents
• Improper disposal of toxics
• Improper use of pesticides and herbicides
Illicit discharges enter the system either through direct connections (deliberate pipe hookups to the storm drain system) or indirect connections (spills collected by drain outlets, or deliberate dumping down the storm drain). These illicit discharges drain directly to the creeks and streams and may be loaded with large amounts of harmful and toxic substances. If you notice illicit discharges, please report them to Plainfield Township at 610-759-6944 or the Northeast Regional Office of the Commonwealth of Pennsylvania Department of Environmental Protection (DEP) at 570-826-2511.
