The Department of Energy has agreed to hold a 30-day review and comment period on a draft environmental analysis associated with a proposed plan for retrieving, grouting, and transporting some of Hanford’s low-activity tank waste for out-of-state disposal.

The U.S. Department of Energy, Washington State Department of Ecology, and U.S. Environmental Protection Agency have reached an agreement on revised plans for managing millions of gallons of radioactive and chemical liquid waste stored in 177 underground tanks at the Hanford Site near Richland, Wash.
