Storm Water Quality Reporting

What is an Illicit Discharge?

An illicit discharge is any discharge to a MS4 conveyance that is not composed entirely of stormwater, except naturally introduced floatables, such as leaves or tree limbs.  The stormwater drainage system includes street curbs and gutters, ditches, catch basins, yard inlets, and underground storm pipes.

Examples of an Illicit Discharge include:

  • Pouring paint or other chemicals into or near the storm drainage system.
  • Changing oil or antifreeze over or near a storm structure and allowing the liquid to flow into the storm drainage system.
  • Washing vehicles where the runoff could drain into the storm drainage system.
  • Washing dumpster pads and allowing the runoff to drain into the storm drainage system.
  • Dumping grass clippings into a stormwater basin or inlet or into the street.

Illicit discharges cause water pollution by sending pollutants directly into creeks, streams, ponds, and lakes. Be sure you know what illicit discharges are so you can help prevent water pollution and keep our streams clean!

Illicit discharges and stormwater quality issues should be reported to the City at (260) 624-2663. See more information and examples in this short video.
