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: 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...
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...
Environmental Enforcement: EPA Needs to Improve the Accuracy and Transparency of Measures Used to Report on Program Effectiveness
GAO-08-1111R: Published: Sep 18, 2008. Publicly Released: Oct 21, 2008.
As part of its mission to protect human health and the environment, the Environmental Protection Agency's (EPA) enforcement office maintains civil and criminal enforcement programs to help enforce the requirements of major federal environmental laws such as the Clean Air Act and the Clean Water Act. EPA's civil and criminal enforcement programs work with the Department of Justice (DOJ), and in som...
Climate Change: Federal Actions Will Greatly Affect the Viability of Carbon Capture and Storage As a Key Mitigation Option
GAO-08-1080: Published: Sep 30, 2008. Publicly Released: Sep 30, 2008.
Key scientific assessments have underscored the urgency of reducing emissions of carbon dioxide (CO2) to address climate change. Many have cited carbon capture and storage (CCS) as an essential technology because it has the potential to greatly reduce CO2 emissions from power plants while allowing for projected increases in electricity demand. CCS involves capturing CO2 from a power plant's emissi...
Concentrated Animal Feeding Operations: EPA Needs More Information and a Clearly Defined Strategy to Protect Air and Water Quality
GAO-08-1177T: Published: Sep 24, 2008. Publicly Released: Sep 24, 2008.
Concentrated animal feeding operations (CAFO) are large livestock and poultry operations that raise animals in a confined situation. CAFOs may improve the efficiency of animal production, but the large amounts of manure they produce can, if improperly managed, degrade air and water quality. The Environmental Protection Agency (EPA) regulates CAFOs and requires CAFOs that discharge certain pollutan...
Concentrated Animal Feeding Operations: EPA Needs More Information and a Clearly Defined Strategy to Protect Air and Water Quality from Pollutants of Concern
GAO-08-944: Published: Sep 4, 2008. Publicly Released: Sep 24, 2008.
Concentrated Animal Feeding Operations (CAFO) are large livestock and poultry operations that raise animals in a confined situation. CAFOs can improve the efficiency of animal production but large amounts of manure produce can, if not properly managed, degrade air and water quality. The Environmental Protection Agency (EPA) is responsible for regulating CAFOs and requires CAFOs that discharge cert...
Environmental Health: EPA Efforts to Address Children's Health Issues Need Greater Focus, Direction, and Top-Level Commitment
GAO-08-1155T: Published: Sep 16, 2008. Publicly Released: Sep 16, 2008.
According to EPA, children face disproportionate risks from contaminants such as air pollution and lead paint. The health consequences to the country's 74 million children are significant. In 2006, 55 percent of children lived in counties exceeding allowable levels for at least one of the six principal air pollutants such as ozone which causes or aggravates asthma. Asthma is the third-most common...
Aboveground Oil Storage Tanks: More Complete Facility Data Could Improve Implementation of EPA's Spill Prevention Program
GAO-08-482: Published: Apr 30, 2008. Publicly Released: May 30, 2008.
Oil leaks from aboveground tanks have contaminated soil and water, threatening human health and wildlife. To prevent damage from oil spills, the Environmental Protection Agency (EPA) issued the Spill Prevention, Control, and Countermeasure (SPCC) rule in 1973. EPA's 10 regions inspect oil storage facilities to ensure compliance with the rule. EPA estimates that about 571,000 facilities are subject...
