Mission | About Us

Washington Closure Hanford manages the $2.3 billion, 10-year River Corridor Closure Project for the U.S. Department of Energy.

Located on the 586-square-mile Hanford Site in southeastern Washington state, the 220-square-mile River Corridor comprises the outer edge of the Hanford Site, including major portions of the Hanford Reach National Monument.

Washington Closure was selected by DOE to manage the project in August 2005. The contract runs through September 2015.

Our mission:  Remove the environmental risk and hazards near the Columbia River Corridor through efficient, safe and compliant procedures while safeguarding people and the environment.

River Corridor Cleanup Project Work Scope

The scope of work for the River Corridor Closure Project team is to safely demolish 329 buildings, clean up an estimated 555 waste sites and burial grounds, place the H and N reactors and the 109-N Heat Exchange Building in interim safe storage, and operate the Environmental Restoration Disposal Facility and expand it as necessary.

Cleanup of the Columbia River corridor helps protect the river by removing contaminants that could enter the river. It also supports the U.S. Department of Energy's vision for cleaning up the river corridor and reducing the footprint of active cleanup at Hanford by 2015.

The River Corridor includes the land bordering the Columbia River. Within it, cleanup projects are located in:

• The 100 Area, where plutonium was produced in nine nuclear reactors
• The 300 Area, where uranium was fabricated, manufacturing and waste disposal processes were developed and research was conducted
• The 400 Area, where Fast Flux Test Facility and support facilities are located
• The 600 Area, where two challenging and highly radioactive burial grounds, 618-10 and 618-11, are located.

Washington Closure is a limited liability company owned by URS, Bechtel and CH2M HILL.
