Illicit Discharge Detection and Elimination Program

Per the City of Staunton’s General Permit for Discharges of Stormwater from Small Municipal Separate Storm Sewer Systems (MS4s), the City is required to effectively prohibit, through ordinance or other legal mechanism, any discharge into the City’s storm sewer system and local waterways not composed entirely of stormwater (illicit discharge). Accordingly, the City has developed an Illicit Discharge Detection and Elimination (IDDE) Program to detect, identify and address unauthorized non-stormwater discharges, including illegal dumping.



The City's Illicit Discharge Detection and Elimination Program (IDDE) is our continuing effort to seek out and/or respond to any unlawful act of disposing, dumping, spilling, or other discharge of any substance other than stormwater into the City's storm drain system which would cause an impact to our streams and tributaries. The IDDE program consists of the following:

  • Annual screenings of storm sewer outfalls to detect illicit discharges. If an illicit discharge is found, it will be investigated to determine the source, and procedures will be followed to eliminate the discharge.
  • We have created an email - , and hotline - (540) 213-6517, for citizens to report any suspected (non emergency) illicit discharge so that it may be investigated.
  • The City has adopted an illicit discharge ordinance (Staunton City Code Title 13 - Environmental) . This ordinance defines what an illicit discharge is and provides staff enforcement methods (including legal action) to help eliminate discharges found.
