What is illicit discharge?

Any non-stormwater discharge of a solid, semi-solid or liquid substance into or adjacent to the Stormwater drainage system. Examples include fluids from vehicles, chemicals from drums or storage tanks, oil, grass clippings and yard debris, chlorinated swimming pool water, and fertilizer.
