EPCRA Emergency Release Notifications

Emergency Planning and Community Right-to-Know Act Section 304

If a release of an Extremely Hazardous Substance is at or above its applicable Reportable Quantity, the facility must notify the State or Tribal Emergency Response Commission (SERC or TERC) and the Local or Tribal Emergency Planning Committee (LEPC or TEPC) for any area(s) likely to be affected by the release. If it is an accidental release of a hazardous substance listed under the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA), the facility must notify the National Response Center, as well as the State or Tribal Emergency Response Commission (SERC or TERC) and the Local or Tribal Emergency Planning Committee (LEPC or TEPC).

  • Find your State Emergency Release Contacts.
  • The National Response Center can be reached at 1 (800) 424-8802 and in Washington, DC at (202) 267-2675.

The facility must also provide a detailed follow-up written report as soon as practicable after the release. State or Tribal Emergency Response Commissions (SERCs or TERCs) and Local or Tribal Emergency Planning Committees (LEPCs or TEPCs) are required to make these reports available to the public.
