Reporting Illegal Discharges

"An illegal discharge is defined as any disposal into the storm drain system for which a person or business does not have a permit."

Federal and State laws currently prohibit the discharge of certain non-stormwaters to the storm drain system. The purpose of these regulations is to protect the quality of the nation's surface water resources by minimizing contamination associated with urban activities. Prohibited discharges include industrial process water, sanitary sewer flows, dumping of liquid waste, and other non-storm flows.

The following information is designed to assist you in recognizing potential illegal/illicit discharges into the storm drain system, and provide a method for reporting observations to the appropriate local authorities.


Illegal/illicit dumping and discharges (e.g., trash, oil, sewage, and chemicals) are a major cause of storm water pollution. Public witness complaints provide the most common source of information. Illegal/illicit dumping and discharges should be reported to the jurisdiction where the activity is taking place.
