On July 1, 2026, the U.S. Department of Energy’s Hanford Field Office released an update on its ongoing plans for where and how to treat, transport, and dispose of millions of gallons of radioactive and chemically hazardous tank waste from the west-area tank farms at Hanford. In its letter, U.S. DOE reports that it has decided to not, at this time, construct the facilities necessary to solidify and grout tank waste at the Hanford site. This decision leaves open the option for U.S. DOE to ship radioactive tank waste in liquid form through Oregon. We reiterate Oregon’s long-held position that it is unacceptable for liquid radioactive Hanford tank waste to be transported through our state.
