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...

Hardrock Mining: Information on Abandoned Mines and Value and Coverage of Financial Assurances on BLM Land
GAO-08-574T: Published: Mar 12, 2008. Publicly Released: Mar 12, 2008.
The Mining Act of 1872 helped foster the development of the West by giving individuals exclusive rights to mine gold, silver, copper, and other hardrock minerals on federal lands. However, miners often abandoned mines, leaving behind structures, safety hazards, and contaminated land and water. Four federal agencies--the Department of the Interior's Bureau of Land Management (BLM) and Office of Sur...
Military Training: Compliance with Environmental Laws Affects Some Training Activities, but DOD Has Not Made a Sound Business Case for Additional Environmental Exemptions
GAO-08-407: Published: Mar 7, 2008. Publicly Released: Mar 7, 2008.
A fundamental principle of military readiness is that the military must train as it intends to fight, and military training ranges allow the Department of Defense (DOD) to accomplish this goal. According to DOD officials, heightened focus on the application of environmental statutes has affected the use of its training areas. Since 2003, DOD has obtained exemptions from three environmental laws an...
Bureau of Reclamation: Reimbursement of California's Central Valley Project Capital Construction Costs by San Luis Unit Irrigation Water Districts

Coastal Wetlands: Lessons Learned from Past Efforts in Louisiana Could Help Guide Future Restoration and Protection
GAO-08-130: Published: Dec 14, 2007. Publicly Released: Dec 14, 2007.
Louisiana, home to 40 percent of all coastal wetlands in the lower 48 states, is projected to lose almost 17 square miles of coastline each year for the next 50 years to storms, sea level rise, and land subsidence. Coastal wetlands are an important wildlife and commercial resource, and provide a natural buffer against the storm surge that accompanies storms and hurricanes. The Coastal Wetlands Pla...
