Hazardous Waste Programs: Information on Appropriations and Expenditures for Superfund, Brownfields, and Related Programs
GAO-05-746R: Published: Jun 30, 2005. Publicly Released: Jul 6, 2005.
Our July 2003 report on the status of the Environmental Protection Agency's (EPA) Superfund program included, among other things, data on the program's appropriations and expenditures for fiscal years 1993 to 2002. In February 2004, we issued a report updating that information and, in May 2004, we broke down the appropriations data, reporting the amounts for the Superfund program as well as amount...
Groundwater Contamination: DOD Uses and Develops a Range of Remediation Technologies to Clean Up Military Sites
GAO-05-666: Published: Jun 30, 2005. Publicly Released: Jun 30, 2005.
To date, the Department of Defense (DOD) has identified nearly 6,000 sites at its facilities that require groundwater remediation and has invested $20 billion over the past 10 years to clean up these sites. In the past, DOD primarily used "pump-and-treat" technologies to contain or eliminate hazardous contaminants in groundwater. However, the long cleanup times and high costs of using pump-and-tre...
Clean Air Act: Emerging Mercury Control Technologies Have Shown Promising Results, but Data on Long-Term Performance Are Limited
GAO-05-612: Published: May 31, 2005. Publicly Released: Jun 23, 2005.
In March 2005, the Environmental Protection Agency (EPA) issued a rule that will limit emissions of mercury--a toxic element that causes neurological problems--from coal-fired power plants, the nation's largest industrial source of mercury emissions. Under the rule, mercury emissions are to be reduced from a baseline of 48 tons per year to 38 tons in 2010 and to 15 tons in 2018. In the rule, EPA s...
Storm Water Pollution: Information Needed on the Implications of Permitting Oil and Gas Construction Activities
GAO-05-240: Published: Feb 9, 2005. Publicly Released: Mar 14, 2005.
To prevent pollutants from entering storm water runoff, the Clean Water Act's National Pollutant Discharge Elimination System Storm Water Program requires controls for construction activities that disturb land. Phase I of this program requires permitting for construction activities that disturb 5 acres or more, while Phase II requires permitting for activities disturbing between 1 and 5 acres. The...
Clean Air Act: Observations on EPA's Cost-Benefit Analysis of Its Mercury Control Options
GAO-05-252: Published: Feb 28, 2005. Publicly Released: Mar 7, 2005.
Mercury is a toxic element that can cause neurological disorders in children. In January 2004, the Environmental Protection Agency (EPA) proposed two options for limiting mercury from power plants, and plans to finalize a rule in March 2005. The first would require each plant to meet emissions standards reflecting the application of control technology (the technology-based option), while the secon...
Grants Management: EPA Needs to Strengthen Efforts to Provide the Public with Complete and Accurate Information on Grant Opportunities
GAO-05-149R: Published: Feb 3, 2005. Publicly Released: Feb 3, 2005.
The Environmental Protection Agency (EPA) has faced persistent challenges for many years in managing its grants, which constitute over one-half of the agency's budget, or about $4 billion annually. Among other things, EPA has been criticized for not always promoting competition in awarding grants, including not completely and accurately announcing grant opportunities to the public and potential ap...
Environmental Protection: Recommendations for Improving the Underground Storage Tank Program
GAO-03-529T: Published: Mar 5, 2003. Publicly Released: Mar 5, 2003.
Nationwide, underground storage tanks (UST) containing petroleum and other hazardous substances are leaking, thereby contaminating the soil and water, and posing health risks. The Environmental Protection Agency (EPA), which implements the UST program with the states, required tank owners to install leak detection and prevention equipment by the end of 1993 and 1998 respectively. The Congress aske...
Federal Procurement: Government Agencies' Purchases of Recycled-Content Products
GAO-02-928T: Published: Jul 11, 2002. Publicly Released: Jul 11, 2002.
In the Resource Conservation and Recovery Act of 1976, Congress directed the Environmental Protection Agency (EPA) to identify products made with recycled waste materials or solid waste by-products and to develop guidance for purchasing these products. The act also requires procuring agencies to establish programs for purchasing these products. Procuring agencies, which can include contractors and...
Environmental Protection: MTBE Contamination From Underground Storage Tanks
GAO-02-753T: Published: May 21, 2002. Publicly Released: May 21, 2002.
To help limit air pollution, about a third of the states use gasoline that contains methyl tertiary butyl ether (MTBE), which burns cleaner. However, MTBE has migrated into wells and groundwater from leaking underground tanks used to store gasoline. The Environmental Protection Agency (EPA) has the responsibility through the Underground Storage Tank Program and works through the states to ensure t...
Environmental Protection: Improved Inspections and Enforcement Would Ensure Safer Underground Storage Tanks
GAO-02-712T: Published: May 8, 2002. Publicly Released: May 8, 2002.
Hazardous substances that leak from underground storage tanks can contaminate the soil and water and pose continuing health risks. Leaks of methyl tertiary butyl ether--a fuel additive--have forced several communities to close their wells. GAO surveyed all 50 states and the District of Columbia to determine whether tanks are compliant with the Environmental Protection Agency's (EPA) underground st...
