Radiological Hazards

Nuclear Power Plant Emergency Planning

Nuclear power plants are required to have detailed emergency plans to protect the public in the event of an accident that could result in the release of radioactivity. Maine Emergency Management Agency is responsible for maintaining Maine's nuclear plant emergency plans. Those plans are reviewed and updated annually.

Emergency plans for nuclear power plants are regulated by the Nuclear Regulatory Commission and the Federal Emergency Management Agency, which supervise graded exercises of those plans.

An important State partner in nuclear plant emergency planning is the which coordinates nuclear safety and makes public health protective action recommendations for the State.

Maine does not have any nuclear power plants within its own borders. However two nuclear power plants may have an impact in Maine within an area known as the Ingestion Exposure Pathway Zone (IPZ).  These plants are located in Seabrook New Hampshire and Point LePreau, New Brunswick.

The IPZ is a 50 mile area around a nuclear power plant where planning occurs to protect the food chain and environment. Human health is also a consideration but direct exposure from radiation is not expected beyond the 10 mile Emergency Planning Zone (EPZ). No portion of Maine falls within the EPZ of either facility.

The Seabrook IPZ includes the majority of towns in York County, Maine. The Point LePreau IPZ covers approximately half of the Washington County towns.
