The notice required by section 304 of EPCRA is to be given by the owner or operator of a facility (by telephone, radio, or in person) immediately after the release of a CERCLA hazardous substance or of an EHS at or above the RQ. Notice is to be given to:
- both the community emergency coordinator for each LEPC for any area likely to be affected by the release and
- to the SERC of any State likely to be affected by the release.
Notice requirements for transportation-related releases are satisfied by dialing 911 or, in the absence of a 911 number, calling the operator and providing the release information.
