Nuclear Waste: Waste Isolation Pilot Plant Recovery Demonstrates Cost and Schedule Requirements Needed for DOE Cleanup Operations
GAO-16-608: Published: Aug 4, 2016. Publicly Released: Aug 4, 2016.
The Department of Energy (DOE) did not meet its initial cost and schedule estimates for restarting nuclear waste disposal operations at the Waste Isolation Pilot Plant (WIPP), resulting in a cost increase of about $64 million and a delay of nearly 9 months. DOE incurred this cost increase and delay partly because it did not follow all best practices in developing the cost and schedule estimates. I...
Hanford Waste Treatment: DOE Needs to Evaluate Alternatives to Recently Proposed Projects and Address Technical and Management Challenges
GAO-15-354: Published: May 7, 2015. Publicly Released: May 7, 2015.
The Department of Energy's (DOE) two proposed facilities may help achieve Hanford's waste treatment mission by expediting treatment of some waste and addressing some technical challenges within the Waste Treatment and Immobilization Plant's (WTP) Pretreatment facility. However, DOE selected the facilities based on past proposals and excluded other potential alternatives from consideration. One fac...
Uranium Contamination: Overall Scope, Time Frame, and Cost Information Is Needed for Contamination Cleanup on the Navajo Reservation
GAO-14-323: Published: May 5, 2014. Publicly Released: May 5, 2014.
Federal agencies implementing the 2008 5-year plan, including the Environmental Protection Agency (EPA), the Department of Energy, the Bureau of Indian Affairs (BIA), and the Indian Health Service, met the targets in six of the plan's eight objectives, working in cooperation with tribal agencies, including the Navajo Nation Environmental Protection Agency. Reasons agencies met the targets were pri...
Hazardous Waste: Early Goals Have Been Met in EPA's Corrective Action Program, but Resource and Technical Challenges Will Constrain Future Progress
GAO-11-514: Published: Jul 22, 2011. Publicly Released: Aug 25, 2011.
Years of industrial development generated hazardous waste that, when improperly disposed of, poses risks to human health and the environment. To mitigate these risks, Congress passed the Resource Conservation and Recovery Act of 1976 (RCRA). Subtitle C of RCRA, as amended, requires owners or operators to take corrective actions to clean up contamination at facilities that treat, store, or dispose...
Superfund: Information on the Nature and Costs of Cleanup Activities at Three Landfills in the Gulf Coast Region
GAO-11-287R: Published: Feb 18, 2011. Publicly Released: Feb 18, 2011.
The Environmental Protection Agency (EPA) estimates that one in four Americans lives within 3 miles of a contaminated site, many of which pose serious risks to human health and the environment. The Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA) provided the federal government with authority to respond to releases or threatened releases of hazardous substance...
Afghanistan and Iraq: DOD Should Improve Adherence to Its Guidance on Open Pit Burning and Solid Waste Management
GAO-11-63: Published: Oct 15, 2010. Publicly Released: Oct 15, 2010.
From the start of military operations in Afghanistan and Iraq, the U.S. military and its contractors have burned solid waste in open burn pits on or near military bases. According to the Department of Defense (DOD), burn pit emissions can potentially harm human health. U.S. Central Command (CENTCOM) guidance directs the military's use of burn pits, and the Department of Veterans' Affairs (VA) prov...
Nuclear Waste: Actions Needed to Address Persistent Concerns with Efforts to Close Underground Radioactive Waste Tanks at DOE's Savannah River Site
GAO-10-816: Published: Sep 14, 2010. Publicly Released: Sep 14, 2010.
Decades of nuclear materials production at the Department of Energy's (DOE) Savannah River Site in South Carolina have left 37 million gallons of radioactive liquid waste in 49 underground storage tanks. In December 2008, DOE entered into a contract with Savannah River Remediation, LLC (SRR) to close, by 2017, 22 of the highest-risk tanks at a cost of $3.2 billion. GAO was asked to assess: (1) DOE...

Before the passage of federal environmental legislation in the 1970s and 1980s, Department of Defense (DOD) activities contaminated millions of acres of soil and water on and near DOD sites. The Environmental Protection Agency (EPA) has certain oversight authorities for cleaning up contaminants on federal property, and has placed 1,620 of the most contaminated sites--including 141 DOD installation...
Nuclear Waste Management: Key Attributes, Challenges, and Costs for the Yucca Mountain Repository and Two Potential Alternatives
GAO-10-48: Published: Nov 4, 2009. Publicly Released: Dec 2, 2009.
High-level nuclear waste--one of the nation's most hazardous substances--is accumulating at 80 sites in 35 states. The United States has generated 70,000 metric tons of nuclear waste and is expected to generate 153,000 metric tons by 2055. The Nuclear Waste Policy Act of 1982, as amended, requires the Department of Energy (DOE) to dispose of the waste in a geologic repository at Yucca Mountain, ab...
