Emergency Planning Zones
There are two Emergency Planning Zones (EPZ) surrounding PVNGS 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
PVNGS where protective actions could be required to protect the public
from the effects of exposure to radioactive materials. This 10-mile radius
has been divided into 16 sectors designated with the letters A through
R. The letters “I” and “O” have been omitted to
prevent confusion with numbers. The radius is also divided into mile rings
from 1 through 10. This map allows people to determine what sector and
mile ring they are in and their proximity to the plant. The entire area
is roughly bounded by 299th Avenue to the East, Saddle Mountain to the
West, three miles north of Indian School Road to the North and 1 mile
south of Agua Caliente Road to the South. People living within this area
are sent a public information calendar containing an evacuation route
map and emergency information on an annual basis.
To find your location on the EPZ map, first find your sector letter.
Look at the outer ring and choose the section that contains the area where
your home is located. Second, find your mile ring. Count the number of
rings from the center of the diagram. For example, if your home is close
to Baseline and 331st Avenue, you are located in sector E - 6. Once you
locate your sector and mile ring, be sure to make note of it as official
will use sector locations when describing protective measures.

Ingestion Exposure Pathway EPZ
The Ingestion Exposure Pathway is defined as a radius of approximately
50 miles surrounding PVNGS where food or potable water could become contaminated
as a result of a release of radioactive materials into the atmosphere.
The “Radiological Emergency Information for Farmers, Dairy Farmers,
Ranchers, Food Processors, and Distributors” pamphlet is prepared
by the Arizona Division of Emergency Management (ADEM) and distributed to the agricultural community in the 50-mile zone.
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.
