Federal authorities have established 10-mile and 50-mile Emergency Planning Zones as the basis for planning to protect the public from exposure to radiation in the unlikely event of an accident at a nuclear power plant. For areas within 10 miles of a nuclear power plant the planning zone is called the Exposure Path Zone (EPZ), and for areas within 10 to 50 miles of a nuclear power plant the planning zone is called the Ingestion Path Zone (IPZ). The entire City of Haverhill is located within the 50-mile IPZ for Seabrook Nuclear Power Plant, which is located 12 miles north-east of Haverhill in Seabrook, New Hampshire. |

Planning for the 50-mile IPZ includes identifying and monitoring crops that may be consumed by humans or animals, and dairy and/or drinking water facilities or supplies that are located in an open environment that could be exposed to radioactive fallout.
An accident or incident at a nuclear power plant is classified in one of four ways:
- Unusual Event - minor incident such as severe weather.
- Alert - minor incident that could affect reactor safety.
- Site Area Emergency - more serious, reactor could be leaking.
- General Emergency - most severe, radiation release off site possible.
The public within these zones could be notified of such events by a variety of methods, including:
- Radio
- Television
- Door-to-door Notification
- Public Safety Vehicle
- Marine interests via Marine VHF radio
