Hazardous Waste Cleanup: Numbers of Contaminated Federal Sites, Estimated Costs, and EPA's Oversight Role
GAO-15-830T: Published: Sep 11, 2015. Publicly Released: Sep 11, 2015.
The Departments of Agriculture (USDA), the Interior, Defense (DOD), and Energy (DOE) have identified thousands of contaminated and potentially contaminated sites on land they manage but do not have a complete inventory of sites, in particular, for abandoned mines. GAO reported in January 2015 that USDA had identified 1,491 contaminated sites and many potentially contaminated sites. However, USDA d...
Hazardous Waste: Early Goals Have Been Met in EPA's Corrective Action Program, but Resource and Technical Challenges Will Constrain Future Progress
GAO-11-514: Published: Jul 22, 2011. Publicly Released: Aug 25, 2011.
Years of industrial development generated hazardous waste that, when improperly disposed of, poses risks to human health and the environment. To mitigate these risks, Congress passed the Resource Conservation and Recovery Act of 1976 (RCRA). Subtitle C of RCRA, as amended, requires owners or operators to take corrective actions to clean up contamination at facilities that treat, store, or dispose...

Before the passage of federal environmental legislation in the 1970s and 1980s, Department of Defense (DOD) activities contaminated millions of acres of soil and water on and near DOD sites.

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 Liabilities: Hardrock Mining Cleanup Obligations
GAO-06-884T: Published: Jun 14, 2006. Publicly Released: Jun 14, 2006.
Key federal environmental statutes, such as the Resource Conservation and Recovery Act (RCRA) and the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), which established the Superfund program, require that parties statutorily responsible for pollution bear the cost of cleaning up contaminated sites. In many cases, liable parties meet their cleanup responsibilities. Ho...
Hazardous Waste: EPA Needs to Clarify the Types of Mercury Waste That Can Be Treated and Disposed of Using the Debris Regulations
GAO-06-99: Published: Dec 16, 2005. Publicly Released: Jan 17, 2006.
The Environmental Protection Agency (EPA) is responsible for regulating hazardous wastes (such as mercury) under the Resource Conservation and Recovery Act (RCRA). Under RCRA, mercury-containing hazardous waste must meet specific treatment standards before land disposal. But, certain difficult to manage waste due, in part, to its large particle size, can follow alternate "debris" standards that pr...
Hazardous Waste Programs: Information on Appropriations and Expenditures for Superfund, Brownfields, and Related Programs

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...
Hazardous Waste: Effect of Proposed Rule's Extra Cleanup Requirements Is Uncertain
GAO-01-57: Published: Oct 20, 2000. Publicly Released: Nov 20, 2000.
The Environmental Protection Agency (EPA) proposed several amendments to its 1993 Corrective Action Management Unit (CAMU) rule. The CAMU rule currently allows agencies to set aside part of their hazardous waste site to deposit wastes without triggering the requirements of the Recovery Conservation and Recovery Act (RCRA). EPA's action is in response to a lawsuit alleging that the CAMU rule would...
