Displays data from the FCC National Broadband Map showing Mobile Voice Coverage within the 10 mile EPZs. This data layer shows outdoor cellular voice coverage from a mobile car (Mobile Coverage) or from a stationary location (Fringe Coverage). This is used as an approximation of IPAWS message delivery and coverage may vary due to several factors, including by not limited to topography and weather. Please note this does not account for indoor coverage, which may also vary depending on building material. Coverage is stored in hexagonal buckets.
This layer is valid as of June 2025 (uploaded on November 22, 2025 to the FCC National Broadband Map). Data updates are typically in May and November.

<div style='text-align:Left;'><div><div><p><span>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. </span></p><p><span>Background on the REPP</span></p><p><span>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.</span></p><p><span /></p></div></div></div>
