is declared when an event has occurred that could reduce the plant's level of
safety, but backup plant systems still work. Emergency agencies are notified and
kept informed, but no action by the public is necessary.

Site Area Emergency
is declared when an event involving major problems with the plant's safety
systems has progressed to the point that a release of some radioactivity into
the air or water is possible, but is not expected to exceed Environmental
Protection Agency Protective Action Guidelines (PAGs) beyond the site boundary.
Thus, no action by the public is necessary.

General Emergency
is the most serious of the four classifications and is declared when an event at
the plant has caused a loss of safety systems. If such an event occurs,
radiation could be released that would travel beyond the site boundary. State
and local authorities will take action to protect the residents living near the
plant. The alert and notification system will be sounded. People in the affected
areas could be advised to evacuate promptly or, in some situations, to shelter
in place. When the sirens are sounded, you should listen to your radio,
television and tone alert radios for site-specific information and instructions. |
