Emergency Planning Zones

There are 2 Emergency Planning Zones (EPZ) surrounding PVGS and they are defined as the Plume Exposure Pathway EPZ and the Ingestion Exposure Pathway EPZ.

Plume Exposure Pathway EPZ

The Plume Exposure Pathway is defined as a radius of 10 miles surrounding PVGS where protective actions (shelter-in-place and/or evacuation) could be required to protect the public from the effects of exposure to radiation. The entire area is roughly bounded by 299th Avenue to the East, Saddle Mountain to the West, 3 miles north of Indian School Road to the North and 1 mile south of Agua Caliente Road to the South.

Ingestion Exposure Pathway EPZ

The Ingestion Exposure Pathway is defined as a radius of approximately 50 miles surrounding PVGS where food or potable water could become contaminated as a result of a release of radioactive materials into the atmosphere. Contamination control measures would be implemented to protect the public from ingesting any contaminated food or water. State and County governments are prepared to quickly notify and advise on what actions to take in the event of a radiological emergency.
