Electronic Waste: Harmful U.S. Exports Flow Virtually Unrestricted Because of Minimal EPA Enforcement and Narrow Regulation
GAO-08-1166T: Published: Sep 17, 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 damage health and the environment. Items with cathode-ray tubes (CRTs) are particularly harmful because they contain lead, a know...
Nuclear Waste: DOE Lacks Critical Information Needed to Assess Its Tank Management Strategy at Hanford
GAO-08-793: Published: Jun 30, 2008. Publicly Released: Jun 30, 2008.
The Department of Energy (DOE) manages more than 56 million gallons of radioactive and hazardous waste stored in 149 single-shell and 28 double-shell underground tanks at its Hanford Site in Washington State. Many of these aging tanks have already leaked waste into the soil. Meanwhile, DOE's planned process for emptying the tanks and treating the waste--mixing it with molten glass and solidifying...
Nuclear Material: Several Potential Options for Dealing with DOE's Depleted Uranium Tails Could Benefit the Government
GAO-08-613T: Published: Apr 3, 2008. Publicly Released: Apr 3, 2008.
Since the 1940s, the Department of Energy (DOE) has been processing natural uranium into enriched uranium, which has a higher concentration of the isotope uranium-235 that can be used in nuclear weapons or reactors. This has resulted in over 700,000 metric tons of leftover depleted uranium, also known as "tails," that have varying residual concentrations uranium-235. The tails are stored at DOE's...
Nuclear Material: DOE Has Several Potential Options for Dealing with Depleted Uranium Tails, Each of Which Could Benefit the Government
GAO-08-606R: Published: Mar 31, 2008. Publicly Released: Apr 2, 2008.
Since the 1940s, one mission of the Department of Energy (DOE) and its predecessor agencies has been processing uranium as a source of nuclear material for defense and commercial purposes. A key step in this process is the enrichment of natural uranium, which increases its concentration of uranium-235, the isotope of uranium that undergoes fission to release enormous amounts of energy. Before it c...
Hazardous Waste: Information on How DOD and Federal and State Regulators Oversee the Off-Site Disposal of Waste from DOD Installations
GAO-08-74: Published: Nov 13, 2007. Publicly Released: Nov 13, 2007.
Military installations operated by the Department of Defense (DOD) can generate hazardous waste during routine operations, such as the repair and maintenance of weapon systems and equipment, or during an environmental cleanup related to past operations. The proper disposal of hazardous waste, especially when it is taken to an off-site location, is essential to ensuring the health and safety of com...
Hazardous Waste: EPA's National and Regional Ombudsmen Do Not Have Sufficient Independence
GAO-01-813: Published: Jul 27, 2001. Publicly Released: Sep 14, 2001.
Through the impartial and independent investigation of citizens' complaints, federal ombudsmen provide the public with an informal and accessible avenue of redress. Ombudsmen help federal agencies be more responsive to persons who believe that their concerns have not been dealt with fully or fairly through normal problem-solving channels. A national hazardous waste ombudsman was established at the...
