Superfund: Trends in Federal Funding and Cleanup of EPA's Nonfederal National Priorities List Sites
GAO-15-812: Published: Sep 25, 2015. Publicly Released: Oct 26, 2015.
Annual federal appropriations to the Environmental Protection Agency's (EPA) Superfund program generally declined from about $2 billion to about $1.1 billion in constant 2013 dollars from fiscal years 1999 through 2013. EPA expenditures—from these federal appropriations—of site-specific cleanup funds on remedial cleanup activities at nonfederal National Priorities List (NPL) sites declined fro...
Chemical Assessments: An Agencywide Strategy May Help EPA Address Unmet Needs for Integrated Risk Information System Assessments
GAO-13-369: Published: May 10, 2013. Publicly Released: Jun 10, 2013.
The Environmental Protection Agency (EPA) has not conducted a recent evaluation of demand for Integrated Risk Information System (IRIS) toxicity assessments with input from users inside and outside EPA. Specifically, EPA issued a needs assessment report in 2003, which estimated that 50 new or updated IRIS toxicity assessments were needed each year to meet users' needs. However, GAO did not find su...
Superfund: EPA's Costs to Remediate Existing and Future Sites Will Likely Exceed Current Funding Levels
GAO-10-857T: Published: Jun 22, 2010. Publicly Released: Jun 22, 2010.
This testimony summarizes the findings of our report on funding issues related to the Environmental Protection Agency's (EPA) Superfund program. To protect human health and the environment from the effects of hazardous substances, Congress enacted the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) in 1980, which established the Superfund program. Since 1980, EPA has...
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...
Nuclear Waste: DOE Lacks Critical Information Needed to Assess Its Tank Management Strategy at Hanford
GAO-08-793: Published: Jun 30, 2008. Publicly Released: Jun 30, 2008.
The Department of Energy (DOE) manages more than 56 million gallons of radioactive and hazardous waste stored in 149 single-shell and 28 double-shell underground tanks at its Hanford Site in Washington State. Many of these aging tanks have already leaked waste into the soil. Meanwhile, DOE's planned process for emptying the tanks and treating the waste--mixing it with molten glass and solidifying...
Environmental Protection: EPA-State Enforcement Partnership Has Improved, but EPA's Oversight Needs Further Enhancement
GAO-07-883: Published: Jul 31, 2007. Publicly Released: Jul 31, 2007.
The Environmental Protection Agency (EPA) enforces the nation's environmental laws through its Office of Enforcement and Compliance Assurance (OECA). OECA sets overall enforcement policies and through its 10 regions oversees state agencies authorized to implement environmental programs consistent with federal requirements. GAO was asked to (1) identify trends in federal resources to regions and st...
Leaking Underground Storage Tanks: EPA Should Take Steps to Better Ensure the Effective Use of Public Funding for Cleanups
GAO-07-152: Published: Feb 8, 2007. Publicly Released: Feb 22, 2007.
Underground storage tanks that leak hazardous substances can contaminate nearby groundwater and soil. Under the Resource Conservation and Recovery Act (RCRA), tank owners and operators are primarily responsible for paying to clean up releases from their tanks. They can demonstrate their financial responsibility by using, among other options, publicly funded state financial assurance funds. Such fu...
Environmental Protection: More Complete Data and Continued Emphasis on Leak Prevention Could Improve EPA's Underground Storage Tank Program
GAO-06-45: Published: Nov 30, 2005. Publicly Released: Nov 30, 2005.
Leaking underground storage tanks that contain hazardous products, primarily gasoline, can contaminate soil and groundwater. To address this problem, the Environmental Protection Agency (EPA), under its Underground Storage Tank (UST) Program, required tank owners to install leak detection equipment and take measures to prevent leaks. In 1986, the Congress created a federal trust fund to assist sta...
Environmental Contamination: DOD Has Taken Steps to Improve Cleanup Coordination at Former Defense Sites but Clearer Guidance Is Needed to Ensure Consistency
GAO-03-146: Published: Mar 28, 2003. Publicly Released: Apr 28, 2003.
The U.S. Army Corps of Engineers (Corps) is in charge of addressing cleanup at the more than 9,000 U.S. properties that were formerly owned or controlled by the Department of Defense (DOD) and have been identified as potentially eligible for environmental cleanup. The Corps has determined that more than 4,000 of these properties have no hazards that require further Corps study or cleanup action. H...
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...
