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...
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...
Superfund: Interagency Agreements and Improved Project Management Needed to Achieve Cleanup Progress at Key Defense Installations
GAO-10-348: Published: Jul 15, 2010. Publicly Released: Aug 16, 2010.
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...
Coal Combustion Residue: Status of EPA's Efforts to Regulate Disposal
GAO-10-85R: Published: Oct 30, 2009. Publicly Released: Oct 30, 2009.
On December 22, 2008, a breach in a surface impoundment (or storage pond) dike at the Tennessee Valley Authority (TVA) Kingston Fossil Plant in Tennessee resulted in the release of 5.4 million cubic yards of coal ash--also referred to as coal combustion residue (CCR)--into the nearby Emory River. The spill covered more than 300 acres and made 3 homes uninhabitable; it damaged 23 other homes, plus...
Superfund: Greater EPA Enforcement and Reporting Are Needed to Enhance Cleanup at DOD Sites
GAO-09-278: Published: Mar 13, 2009. Publicly Released: Apr 16, 2009.
Prior to the 1980s and the passage of environmental legislation--particularly the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) governing environmental cleanup--Department of Defense (DOD) activities contaminated millions of acres of soil and water on and near DOD sites. The Environmental Protection Agency (EPA), which enforces CERCLA, places the most contaminated...
Department of Energy: Contract and Project Management Concerns at the National Nuclear Security Administration and Office Of Environmental Management

The Department of Energy (DOE) manages over 100 construction projects with estimated costs over $90 billion and 97 nuclear waste cleanup projects with estimated costs over $230 billion. DOE has about 14,000 employees to oversee the work of more than 93,000 contractor employees. Due to DOE's history of inadequate oversight and management of contractors, GAO continues to include DOE contract and pro...
Electronic Waste: EPA Needs to Better Control Harmful U.S. Exports through Stronger Enforcement and More Comprehensive Regulation
GAO-08-1044: Published: Aug 28, 2008. Publicly Released: Sep 17, 2008.
Increasingly, U.S. consumers are recycling their old electronics to prevent the environmental harm that can come from disposal. Concerns have grown, however, that some U.S. companies are exporting these items to developing countries, where unsafe recycling practices can cause health and environmental problems. Items with cathode-ray tubes (CRT) are particularly harmful because they can contain 4 p...
