West Valley SEIS

Supplemental Environmental Impact Statement (SEIS) for West Valley Site


Who is Preparing the SEIS?


The U.S. Department of Energy’s (DOE's) Office of Environmental Management and the New York State Energy Research and Development Authority (NYSERDA) are jointly preparing the Supplemental Environmental Impact Statement (SEIS) for the West Valley Site.

DOE and NYSERDA invite Federal, state, and local agencies with jurisdiction by law or special expertise to participate in the SEIS as cooperating or involved agencies. At this time, the U.S. Environmental Protection Agency, U.S. Nuclear Regulatory Commission, and New York State Department of Environmental Conservation (NYSDEC) will participate as cooperating agencies under the National Environmental Policy Act. NYSDEC and the New York State Department of Health will also participate as involved agencies under the State Environmental Quality Review Act with respect to NYSERDA’s proposed actions.


About DOE Office of Environmental Management

The Office of Environmental Management within DOE is responsible for the risk reduction and cleanup of the environmental legacy of the Nation's nuclear weapons program, one of the largest, most diverse, and technically complex environmental programs in the world. In addition to its emphasis on site cleanup and closures, the office is also focusing on longer-term activities required for the completion of the cleanup program. These include:

  • Constructing and operating facilities to treat radioactive liquid tank waste into a safe, stable form to enable ultimate disposition.
  • Securing and storing nuclear material in a stable, safe configuration in secure locations to protect national security.
  • Transporting and disposing of transuranic and low-level wastes in a safe and cost-effective manner to reduce risk.

The Office of Environmental Management is the DOE office implementing this task for the West Valley Site, with local support from the West Valley Site Office in Ashford, New York.
