Concord FAQ
What counts as an illicit discharge?
Anything other than rain water going into the storm drain - wash water, paint, oil, pool water, pet waste, sediment, chemicals. Exempt items include residential car wash runoff and AC condensate.
What if I accidentally spilled something into the gutter?
Stop the source, contain with absorbent materials, and call Concord Public Works or the CCCWP hotline. Prompt cleanup reduces penalties.
