At its Hanford Site in Washington State, the Department of Energy (DOE) is responsible for one of the world's biggest cleanup projects: the treatment and disposal of about 56 million gallons of radioactive and hazardous waste, stored in 177 underground tanks. Two decades and several halted efforts later, none of this waste has yet been treated, cleanup costs have grown steadily, and prospective cleanup time frames have lengthened. GAO was asked to assess (1) DOE's current tank waste cleanup strategy and key technical, legal, and other uncertainties; (2) the extent to which DOE has analyzed whether this strategy is commensurate with risks from the wastes; and (3) opportunities to reduce tank waste cleanup costs. GAO reviewed pertinent documents, visited the site, and interviewed officials and independent experts. GAO is recommending that, for Hanford, DOE (1) improve its lifecycle cost and schedule estimates, (2) adopt a risk assessment framework that considers available guidance, (3) consider seeking congressional clarification about reclassifying its high-level tank waste, and (4) work with regulators
