Federal Superfund sites, also referred to as National Priority
List (NPL) sites, are those considered high priority for cleanup
under the federal Superfund Program. These are sites where known
or suspected environmental contamination threatens public health
or the environment. The <a href="http://www.epa.gov">U.S.
Environmental Protection Agency</a> updates the NPL once a
year. For more information, visit the <a

NFRAP, or &quot;No Further Remedial Action Planned&quot; sites,
are the
sites that have been removed from the CERCLIS list by the U.S.
Environmental Protection Agency. These sites are no longer
considered a federal concern, and most are also a low priority
for the state. For more information, contact the MPCA at 651-

Suspected hazardous waste sites throughout the United States are
listed in the Comprehensive Environmental Response, Compensation
and Liability Information System, or CERCLIS. This federal
database contains information on preliminary assessments,
potential and actual hazardous waste sites, site inspections,
and cleanup activities.

The Voluntary Investigation and Cleanup (VIC) Program allows
buyers, sellers, developers or local governments to voluntarily
investigate and, if necessary, clean up contaminated land to
facilitate its sale, financing or redevelopment. Voluntary
parties that complete investigation and/or cleanup activities
under MPCA oversight can receive liability assurances that
protect them from future Superfund liability. In some cases,
the MPCA may use Institutional Controls as part of the overall

PCBs, or polychlorinated biphenyls, are a type of industrial
chemical once used in electronic and hydraulic products. They
are classified as a probable human carcinogen. PCBs are no
longer manufactured, but are still found in the environment
because they do not easily break down.
