Illicit Discharge and Detection Program
Illicit discharges are generally any discharge into a storm drain system this is not composed entirely of stormwater. The exceptions include water from fire fighting activities and discharges from facilities already under a Nation Pollution Discharge Elimination System (NPDES) permit. 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, surfactants, and various toxic pollutants.
The City of Willoughby has developed a program to detect and eliminate these illicit discharges. This primarily includes developing:
- A storm sewer system map
- An ordinance prohibiting illicit discharges
- A plan to detect and address these illicit discharges
- An education program on the hazards associated with illicit discharges.
