In Irvine, California, reporting illicit discharges to the storm drain system helps protect local waterways, public health, and comply with municipal stormwater rules. This guide explains what counts as an illicit discharge, who enforces the rules, how to report a spill or illegal connection, expected enforcement actions, and practical steps for residents and businesses.
