GAO-11-292: Published: Feb 25, 2011. Publicly Released: Feb 25, 2011.
The number of oil and gas wells on leased federal land has increased dramatically. To help manage the environmental impacts of these wells, the Department of the Interior's (Interior) Bureau of Land Management (BLM) requires oil and gas operators to reclaim disturbed land in a manner it prescribes. To help ensure operators reclaim leased land, BLM requires them to provide a bond before beginning d...
Energy-Water Nexus: A Better and Coordinated Understanding of Water Resources Could Help Mitigate the Impacts of Potential Oil Shale Development
GAO-11-35: Published: Oct 29, 2010. Publicly Released: Nov 29, 2010.
Oil shale deposits in Colorado, Utah, and Wyoming are estimated to contain up to 3 trillion barrels of oil--or an amount equal to the world's proven oil reserves. About 72 percent of this oil shale is located beneath federal lands, making the federal government a key player in its potential development. Extracting this oil is expected to require substantial amounts of water and could impact ground...
Surface Coal Mining: Information on Clean Water Act Section 404 Permit Reviews under Enhanced Coordination Procedures in Appalachia, Focusing on West Virginia
GAO-11-101R: Published: Oct 19, 2010. Publicly Released: Nov 18, 2010.
In 2009, West Virginia accounted for about 43 percent of the surface coal mining production in Appalachia. Surface coal mining in the mountainous areas of Appalachia--a process often referred to as mountaintop mining--has generated opposition in recent years because of its impact on landscapes, streams, ecosystems, and communities. In mountaintop mining, before the underlying coal can be extracted...
Climate Change: A Coordinated Strategy Could Focus Federal Geoengineering Research and Inform Governance Efforts
GAO-10-903: Published: Sep 23, 2010. Publicly Released: Oct 26, 2010.
Policymakers have raised questions about geoengineering--large-scale deliberate interventions in the earth's climate system to diminish climate change or its impacts--and its role in a broader strategy of mitigating and adapting to climate change. Most geoengineering proposals fall into two categories: carbon dioxide removal (CDR), which would remove carbon dioxide (CO2) from the atmosphere, and s...

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...
