Columbia Generating Station

Energy Northwest Columbia Generating Station
Benton County Emergency Management, in coordination with Franklin and Grant Counties, the state of Washington and Energy Northwest, has developed plans to respond in the unlikely event of an accident at the Columbia Generating Station (CGS).  CGS is the Northwest's only commercial nuclear power plant and is owned and operated by Energy Northwest.  The plans are designed to help protect nearby residents, specifically those living within the Emergency Planning Zones (EPZ) around the nuclear plant.
Who Is At Risk?
An accident at the Columbia Generating Station involving the release of radioactive material into the surrounding community is very unlikely.  However, plans are in place to protect nearby residents.
Please refer to your calendar sent by Energy Northwest for a map showing the designated Emergency Planning Zones (EPZ) around the nuclear plant.  If you have any questions, please contact us at 509-628-2600.  An electronic version of the map is provided below.
