Under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), who is responsible for reporting releases and when must the report be made?

Section 103 of CERCLA requires the person in charge of a facility or vessel, as soon as he or she has knowledge of a release of a hazardous substance in an amount equal to or greater than an RQ, to report the release immediately to the National Response Center (NRC). The NRC number is 1-800-424-8802, or (202) 267-2675 in the Washington, DC area.
