This is the compilation of the April 6, 2006 hearing on "Oversight of the Department of Energy's Waste Treatment Plant at Hanford," held before the U.S. House of Representatives Subcommittee on Energy and Water Development, and related agencies, of the Committee on Appropriations. From the testimony of Tom Hash: "The Hanford Waste Treatment Plant is a complex of facilities being designed and built to treat highly radioactive waste stored in 177 aging underground tanks. Some of the tanks date back to World War II and 67 have leaked an estimated one million gallons of waste. This waste, the legacy of 50 years of Cold War plutonium production for nuclear weapons, threatens the nearby Columbia River and the millions of people living downstream. The Waste Treatment Plant will immobilize this waste using a process known as vitrification, which mixes the solid and liquid waste with molten glass to create a sturdy waste form capable of safely isolating the waste from the environment." Statements, letters, and materials submitted for the record include those of the following: A.J. Eggenberger, Kim Callan, Tom Hash, and James A. Rispoli.
