Hudson River Natural Resource Damage Assessment

Hudson River Natural Resource Damage Assessment Links

In coordination with the EPA's Hudson River Reassessment, the Hudson River Natural Resource Trustees - the United States Department of the Interior (DOI), the National Oceanic and Atmospheric Administration (NOAA), and the New York State Department of Environmental Conservation (NYSDEC) - are conducting a Natural Resource Damages Assessment (NRDA) associated with General Electric's PCB contamination of the Hudson River below Hudson Falls.

The process has its origins in the natural resource damages (NRD) provisions of the Comprehensive Environmental Response, Compensation and Liability Act, also known as CERCLA or the federal Superfund law.

The overall purpose of these NRD provisions is to compensate the public for natural resource losses they have suffered from the release of hazardous substances by restoring the injured resources and by enhancing natural resources and their use by people. Compensation may be in the form of monetary damages or, preferably, in actual restoration projects. The trustees have been and will continue following the Federal Regulations for Natural Resource Damages Assessments (43 CFR Part 11) to guide this process.

For additional offsite information from DEC co-trustees please see the links listed on the right column of this page under links leaving DEC's website.

This page contains links to documents that outline the NRDA process as well as the studies conducted to support the natural resource damage assessment case (Studies of the Assessment) . A complete description of the process can be found in the Hudson River Natural Resource Damage Assessment - Description of Process.
