Nuclear Waste: Pretreatment Modifications at DOE Hanford's B Plant Should Be Stopped
RCED-91-165: Published: Jun 12, 1991. Publicly Released: Jul 17, 1991.
Pursuant to a congressional request, GAO reviewed the Department of Energy's (DOE) plans to modify its Hanford Site B Plant in Washington to pretreat mixed high-level radioactive waste before the vitrification process to turn it into glass.GAO found that: (1) although DOE was aware that the plant had not met specific federal or DOE regulations since 1987, it failed to timely discuss the compliance...
Hazardous Waste: Data Management Problems Delay EPA's Assessment of Minimization Efforts
RCED-91-131: Published: Jun 13, 1991. Publicly Released: Jul 16, 1991.
Pursuant to a congressional request, GAO reviewed the Environmental Protection Agency's (EPA) efforts to develop baseline and trend data to measure its progress in minimizing hazardous waste generation.GAO found that: (1) EPA underestimated the complexity of developing baseline minimization data; (2) staffing and funding constraints and competing priorities limited EPA efforts to obtain minimizati...
Nuclear Waste: Problems and Delays With Characterizing Hanford's Single-Shell Tank Waste
RCED-91-118: Published: Apr 23, 1991. Publicly Released: May 30, 1991.
Pursuant to a congressional request, GAO reviewed the status of Department of Energy (DOE) efforts to characterize single-shell tank wastes at its Hanford, Washington site, focusing on impediments such as: (1) technological limitations; and (2) safety considerations.GAO found that: (1) due to the number of unresolved issues, DOE was unlikely to complete the first-phase characterization of the sing...
Nuclear Waste: Issues Affecting Land Withdrawal of DOE's Waste Isolation Pilot Project
T-RCED-91-38: Published: Apr 16, 1991. Publicly Released: Apr 16, 1991.
GAO discussed the Department of Energy's (DOE) Waste Isolation Pilot Plant (WIPP). GAO noted that: (1) by fiscal year (FY) 1997, DOE plans to determine whether WIPP meets the Environmental Protection Agency's (EPA) standards for disposal of transuranic waste in repositories and plans to obtain a variance or exception from the Resource Conservation and Recovery Act (RCRA); (2) DOE postponed plans t...
Nuclear Waste: Information on DOE's Interim Transuranic Waste Storage Facilities
RCED-90-166: Published: Jun 8, 1990. Publicly Released: Jul 19, 1990.
Pursuant to a congressional request, GAO reviewed: (1) remaining transuranic (TRU) waste storage capacity at Department of Energy (DOE) interim storage sites and projected dates when capacity will be exceeded; (2) statutory or administrative provisions limiting the amount of waste DOE could store at interim storage sites; and (3) planned alternatives to the Waste Isolation Pilot Plant (WIPP) for s...
Hazardous Waste: Funding of Postclosure Liabilities Remains Uncertain
RCED-90-64: Published: Jun 1, 1990. Publicly Released: Jun 1, 1990.
In response to a congressional request, GAO studied options for managing liabilities associated with hazardous waste disposal facilities after closure.GAO found that the Environmental Protection Agency (EPA): (1) requires facilities obtaining operating permits to design and construct disposal units with waste migration prevention measures; (2) officials have identified activities, such as extended...
Correcting Environmental Problems Facing the Nuclear Weapons Complex
T-RCED-90-85: Published: May 17, 1990. Publicly Released: May 17, 1990.
GAO discussed the Department of Energy's (DOE) efforts to correct the environmental problems facing the nuclear weapons complex. GAO found that: (1) in making nuclear weapons, enormous amounts of hazardous and radioactive wastes are generated, and DOE now faces serious and costly environmental problems; (2) DOE data show that it might cost over $100 billion to address the environmental problems; (...
