Clean Air Act: Preliminary Observations on the Effectiveness and Costs of Mercury Control Technologies at Coal-Fired Power Plants
GAO-09-860T: Published: Jul 9, 2009. Publicly Released: Jul 9, 2009.
The 491 U.S. coal-fired power plants are the largest unregulated industrial source of mercury emissions nationwide, annually emitting about 48 tons of mercury--a toxic element that poses health threats, including neurological disorders in children. In 2000, the Environmental Protection Agency (EPA) determined that mercury emissions from these sources should be regulated, but the agency has not set...
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...
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...
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...
Superfund: Funding and Reported Costs of Enforcement and Administration Activities
GAO-08-841R: Published: Jul 18, 2008. Publicly Released: Aug 18, 2008.
The Environmental Protection Agency (EPA) estimates that one in four Americans lives within 3 miles of a hazardous waste site. To clean up these highly contaminated sites, the Congress established the Superfund program under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) in 1980. EPA, the principal agency responsible for administering the Superfund program, has...
Toxic Chemical Releases: EPA Actions Could Reduce Environmental Information Available to Many Communities
GAO-08-128: Published: Nov 30, 2007. Publicly Released: Dec 12, 2007.
Federal law requires certain facilities that manufacture, process, or use any of 581 toxic chemicals to report annually to the Environmental Protection Agency (EPA) and their state on the amount of those chemicals released into the air, water, or soil. It also requires EPA to make this information available to the public electronically through the Toxics Release Inventory (TRI) database. Facilitie...
Toxic Chemical Releases: Survey of State Toxics Release Inventory Coordinators (GAO-08-129SP), an E-supplement to GAO-08-128
GAO-08-129SP: Published: Nov 30, 2007. Publicly Released: Dec 12, 2007.
This is an E-supplement to GAO-08-128, which was released on November 30, 2007. The Environmental Protection and Community Right-to-Know Act requires certain facilities to submit Toxics Release Inventory (TRI) reports to their respective states, which have a created range of TRI programs. In order to learn about states' TRI activities, we conducted a survey of state TRI coordinators in the 50 stat...
Environmental Right-To-Know: EPA's Recent Rule Could Reduce Availability of Toxic Chemical Information Used to Assess Environmental Justice
GAO-08-115T: Published: Oct 4, 2007. Publicly Released: Oct 4, 2007.
A 1994 Executive Order sought to ensure that minority and low-income populations are not subjected to disproportionately high and adverse health or environ-mental effects from agency activities. In a July 2005 report, GAO made several recommendations to improve the Environmental Protection Agency's (EPA) adherence to these environmental justice principles. The Emergency Planning and Community Righ...
