Service Description: Displays relative cartographic information displaying approximate locations of Emergency Preparedness Zones (EPZ)s for operating commercial nuclear power facilities. The licensee, in coordination with local and state offsite response organizations, develop these zones, taking into account unique geographic features of the area and demographic information, to assign protective actions to the population in the event of an emergency incident at a nuclear power facility. This layer displays the plume exposure pathway emergency preparedness zones, which are typically contained within a 10-mile radius of a nuclear reactor site. These Emergency Preparedness Zones were digitized from state and local plans and public information brochures. For more information on a particular plan, refer to the linked public information material or contact the appropriate state, local, or facility emergency manager.
Information is current as of March 7, 2025.
Updates:
- Population updated for St. Lucie EPZs
- Maryland Zones for Peach Bottom updated based on updates from state and local stakeholders.

Description: Technological Hazards Division (THD) leads the national effort to build and sustain capabilities in local jurisdictions to address technological threats and hazards. THD is a recognized national leader, working alongside our Federal and state, local, tribal, and territorial (SLTT) partners in building capabilities to respond to and recover from technological hazards as they exist now and may evolve in the future. The Radiological Emergency Preparedness Program (REPP) ensures the health and safety of citizens living around commercial nuclear power plants would be adequately protected in the event of a nuclear power plant accident.
Background on the REPP
On December 7, 1979, following the Three Mile Island nuclear power plant accident in Pennsylvania, President Carter transferred the federal lead role in offsite radiological emergency planning and preparedness activities from the U.S. Nuclear Regulatory Commission to the FEMA. FEMA established the Radiological Emergency Preparedness Program to (1) ensure the health and safety of citizens living around commercial nuclear power plants would be adequately protected in the event of a nuclear power plant accident and (2) inform and educate the public about radiological emergency preparedness. REP Program responsibilities encompass only “offsite” activities, that is, state, tribal and local government emergency planning and preparedness activities that take place beyond the nuclear power plant boundaries. Onsite activities continue to be the responsibility of the NRC.
