What is a spill?

A spill differs from an illicit discharge in that it is an unintentional release of something other than stormwater and related to a singular event. Often times spills are associated with an emergency situation such as an automobile crash. The best way to prevent a spill from becoming an illicit discharge is to control the spill to the scene by blocking off all inlets and preventing any materials from leaving the site.

We encourage all spills to be reported so that we can properly clean and follow up to ensure that no illicit discharge has occurred that needs to be addressed so that we can prevent further harm from being done.
