A requirement of ODOT’s Phase I and II storm water permits require the development and implementation of a Storm Water Management Plan (SWMP). A component of ODOT’s SWMP is the Illicit Discharge Detection and Elimination (IIDE) program. The purpose of ODOT’s IDDE Program is to identify and eliminate any discharge to a Municipal Separate Storm Sewer System (MS4). ODOT employees are the eyes of the program and we are relying on you to help us protect our rivers, streams, creeks and lakes.

Tips for reporting an illicit discharge:

  • Estimate the amount of discharge
  • Characteristics of the discharge like color or odor
  • Information on the vehicle or business dumping waste (if applicable)
  • Safety First! Keep your distance. Illicit discharges can be dangerous.
