EPA Envirofacts Data - Superfund National Priorities List Sites
What this map layer shows: The locations of 1,550 Superfund National Priorities List (NPL) sites.
Background Information
Sample Map The Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), commonly known as Superfund, was enacted by Congress on December 11, 1980. This law created a tax on the chemical and petroleum industries and provided broad Federal authority to respond directly to releases or threatened releases of hazardous substances that may endanger public health or the environment. Over 5 years, $1.6 billion was collected, and the tax went to a trust fund for cleaning up abandoned or uncontrolled hazardous waste sites. Superfund National Priorities List (NPL) sites are the most serious uncontrolled or abandoned hazardous waste sites that have been identified for possible long-term remedial action under Superfund. The list is based primarily on the score a site receives from the Hazard Ranking System. The U.S. Environmental Protection Agency (EPA) is required to update the NPL at least once a year. A site must be on the NPL to receive money from Superfund for long-term remedial action. Long-term remedial action is defined as action that stops or substantially reduces a release or threat of a release of hazardous substances, where such a threat is serious but not an immediate threat to public health. The EPA administers the Superfund program in cooperation with individual States and tribal governments and develops approaches and technologies to support efficient hazardous waste cleanup. This map layer was produced by the EPA. The EPA Envirofacts Data - Superfund National Priorities List Sites map layer shows the locations of 1,550 Superfund NPL sites in the United States, Puerto Rico, and the U.S. Virgin Islands as of May, 2005. Descriptive information includes the facility name and identification number. More detailed information on Superfund is available from the EPA Superfund page, and definitions of environmental terms can be found in the EPA Terms of Environment. Maps showing NPL sites in U.S. territories are available on the page for the National Priorities List Sites in the United States.
