Understanding Illicit Discharges

An illicit discharge is any non-stormwater flow into the storm drain system unless explicitly authorized by permit or city rules. Typical examples include vehicle washwater, concrete washout, restaurant grease, industrial process water, and accidental chemical spills. Illicit discharges create public- and environmental-health risks and are subject to investigation and enforcement by city authorities.

How to Report an Illicit Discharge

If you observe a spill or suspect an illicit discharge, document what you see, contain the source if safe to do so, and report to the city. Use the official city stormwater reporting form or call the Public Works complaint line to notify the Stormwater Division. For city reporting and online submission see the City of Elk Grove Stormwater resources page https://www.elkgrovecity.org/services/public-works/stormwater-quality[1]. For code and ordinance references consult the Elk Grove Municipal Code https://library.municode.com/ca/elk_grove/codes/code_of_ordinances[2].

  • Note the date and time of the discharge.
  • Call the Public Works stormwater hotline or use the online reporting tool immediately.
  • Take photos or video showing the source, flow path, and any identifying marks or business activities.
  • If it is an emergency that threatens public safety, call 911 and then notify the city stormwater contact.
