Environmental Contamination: Information on the Funding and Cleanup Status of Defense Sites
GAO-10-547T: Published: Mar 17, 2010. Publicly Released: Mar 17, 2010.
Under the Defense Environmental Restoration Program (DERP), the Department of Defense (DOD) is responsible for cleaning up about 5,400 sites on military bases that have been closed under the Base Realignment and Closure (BRAC) process, as well as 21,500 sites on active bases and over 4,700 formerly used defense sites (FUDS), properties that DOD owned or controlled and transferred to other parties...
Environmental Health: Opportunities for Greater Focus, Direction, and Top-Level Commitment to Children's Health at EPA
GAO-10-545T: Published: Mar 17, 2010. Publicly Released: Mar 17, 2010.
This testimony discusses highlights of GAO's report about the Environmental Protection Agency's (EPA) efforts to institutionalize the protection of children's health. EPA's mission is to protect human health and the environment. As a result of mounting evidence about the special vulnerabilities of the developing fetus and child, the federal government and EPA took several bold steps to make childr...
Surface Coal Mining: Financial Assurances for, and Long-Term Oversight of, Mines with Valley Fills in Four Appalachian States
GAO-10-206: Published: Jan 14, 2010. Publicly Released: Feb 16, 2010.
Surface mining for coal in Appalachia has generated opposition because rock and dirt from mountaintops is often removed and placed in nearby valleys and streams. The Office of Surface Mining Reclamation and Enforcement (OSM) in the Department of the Interior and states with approved programs regulate these mines under the Surface Mining Control and Reclamation Act (SMCRA). The Army Corps of Engine...
Superfund: Litigation Has Decreased and EPA Needs Better Information on Site Cleanup and Cost Issues to Estimate Future Program Funding Requirements
GAO-09-656: Published: Jul 15, 2009. Publicly Released: Aug 14, 2009.
Under the Superfund program, the Environmental Protection Agency (EPA) places the most seriously contaminated sites on the National Priorities List (NPL). EPA may compel site cleanups by parties responsible for contamination, or conduct cleanups itself and have these parties reimburse its costs. The program is funded by a trust fund, which is largely supported by general fund appropriations. GAO w...
Aviation and Climate Change: Aircraft Emissions Expected to Grow, but Technological and Operational Improvements and Government Policies Can Help Control Emissions
GAO-09-554: Published: Jun 8, 2009. Publicly Released: Jun 8, 2009.
Aircraft emit greenhouse gases and other emissions, contributing to increasing concentrations of such gases in the atmosphere. Many scientists and the Intergovernmental Panel on Climate Change (IPCC)--a United Nations organization that assesses scientific, technical, and economic information on climate change--believe these gases may negatively affect the earth's climate. Given forecasts of growth...
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...
Environmental Protection Agency: Major Management Challenges
GAO-09-434: Published: Mar 4, 2009. Publicly Released: Mar 4, 2009.
The Environmental Protection Agency's (EPA) overarching mission is to protect human health and the environment by implementing and enforcing environmental laws intended to improve the quality of the nation's air and water and to protect its land. EPA's policies and programs affect virtually all segments of the economy, society, and government. As such, it operates in a highly complex and controver...
Climate Change Science: High Quality Greenhouse Gas Emissions Data are a Cornerstone of Programs to Address Climate Change
GAO-09-423T: Published: Feb 24, 2009. Publicly Released: Feb 24, 2009.
Elevated levels of greenhouse gases in the atmosphere and the resulting effects on the earth's climate could have significant impacts in the United States and internationally. Potential impacts include a change in sea levels, ecosystems, and ice cover. The United States Congress is considering proposals to limit greenhouse gas emissions using market-based mechanisms that would place a price on emi...
Clean Air Act: Historical Information on EPA's Process for Reviewing California Waiver Requests and Making Waiver Determinations
GAO-09-249R: Published: Jan 16, 2009. Publicly Released: Feb 17, 2009.
Emissions from mobile sources, such as automobiles and trucks, contribute to air quality degradation and can threaten public health and the environment. Under the Clean Air Act, the Environmental Protection Agency (EPA) regulates these emissions. The act generally allows one set of federal standards for new motor vehicle emissions and pre-empts states from adopting or enforcing their own standards...
Aviation and the Environment: Initial Voluntary Airport Low Emissions Program Projects Reduce Emissions, and FAA Plans to Assess the Program's Overall Performance as Participation Increases
GAO-09-37: Published: Nov 7, 2008. Publicly Released: Nov 7, 2008.
In 2003, Congress established a program to reduce airport ground emissions at commercial service airports in areas failing to meet or maintain air quality standards. The Federal Aviation Administration (FAA) administers the Voluntary Airport Low Emissions (VALE) Program and oversees the program's two sources of funding: Airport Improvement Program (AIP) federal grants or Passenger Facility Charges...
