Department of Energy Releases Hanford 300 Area Cleanup Plan
HANFORD, WA - The U.S. Department of Energy has issued its final cleanup plan for the Hanford 300 Area.
The plan released Wednesday is the first of six plans that will cover more than 200 square miles along the Columbia River near the Tri-Cities of Richland, Kennewick, and Pasco.
The plan proposes digging up contaminated soil and waste sites, treating the waste as needed, and disposing of most of it in a Hanford landfill. It also addresses a uranium groundwater plume beneath the 300 Area which allows contaminated water to flow into the Columbia River.
Cleanup of the 300 Area has actually been under way since the 1990s and is expected to be completed by fall 2015.
The waste is left from production of plutonium for nuclear weapons.
