|EPA Envirofacts Data - Superfund National Priorities List Sites
What this map layer shows:
The locations of 1,550 Superfund National Priorities List (NPL) sites.
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
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.
