The EPA defines an illicit discharge as “…any discharge to the municipal separate storm sewer system that is not composed entirely of storm water, except for discharges allowed under a NPDES permit or waters used for firefighting operations.” Illicit discharges result in contaminated/untreated wastewater entering into the storm sewer system. Examples of illicit discharges include failing septic systems and improper floor drain connections to the storm sewer system. Other examples of illicit discharges include the illegal dumping of paint, oil, and debris (including grass and leaves) that eventually make it to the storm system.

In order to detect and eliminate illicit discharges, the City is in the process of developing an inspection and monitoring program. To report an illicit discharge, please contact the Public Works Department at (816) 436-5442 or by e-mail at stormwater@gladstone.mo.us.
