  • (800) 424-8802 – The National Response Center, if the release exceeds federal reportable quantities.
When reporting the incident, the following minimum information will be required as specified in the California Hazardous Materials Spill/Release Notification Guide:
  • The identity of caller;
  • The location, date and time of spill, release, or threatened release;
  • The location of threatened or involved waterway or storm drains;
