Federal Land Management: Additional Documentation of Agency Experiences with Good Neighbor Authority Could Enhance Its Future Use
GAO-09-277: Published: Feb 25, 2009. Publicly Released: Mar 25, 2009.
In 2000, Congress authorized the U.S. Department of Agriculture's Forest Service to allow the Colorado State Forest Service to conduct certain activities, such as reducing hazardous vegetation, on U.S. Forest Service land when performing similar activities on adjacent state or private land. The Department of the Interior's Bureau of Land Management (BLM) received similar "Good Neighbor" authority...
Hazardous Materials: EPA's Assessment of Sites That May Have Received Asbestos-Contaminated Ore from Libby, Montana (GAO-09-7SP, March 2009), an E-supplement to GAO-09-6R
GAO-09-7SP: Published: Mar 10, 2009. Publicly Released: Mar 10, 2009.
Vermiculite, a fibrous mineral with many commercial and industrial uses, was mined in Libby, Montana, from 1923 through the early 1990s, when the mine was closed. While the mine was operating, ore was shipped to hundreds of processing and receiving sites throughout the United States. The vermiculite ore from the Libby mine was contaminated with asbestos. In 2000, EPA began cleaning up asbestos con...
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...
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...
Hurricane Katrina: Continuing Debris Removal and Disposal Issues
GAO-08-985R: Published: Aug 25, 2008. Publicly Released: Aug 25, 2008.
In 2005, as a result of Hurricane Katrina, more than 1,600 people lost their lives and more than a million were driven from their homes on the Gulf Coast. Tens of thousands of homes in New Orleans were flooded, many requiring either demolition or gutting before reconstruction. Nearly 3 years later, the New Orleans area still faces significant debris management issues and challenges. For example, t...
Chemical Safety Board: Improvements in Management and Oversight Are Needed
GAO-08-864R: Published: Aug 22, 2008. Publicly Released: Aug 22, 2008.
The principal role of the Chemical Safety and Hazard Investigation Board (CSB) is to investigate accidental releases of regulated or extremely hazardous substances to determine the conditions and circumstances that led to the accident and to identify the cause or causes so that similar accidents might be prevented. Accidental releases of these toxic and hazardous chemicals occur frequently and oft...
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...
