7590-01-PUNITED STATES NUCLEAR REGULATORY COMMISSIONENTERGY NUCLEAR VERMONT YANKEE, LLC, AND ENTERGY NUCLEAR OPERATIONS, INC.VERMONT YANKEE NUCLEAR POWER STATIONNOTICE OF AVAILABILITY OF THE FINAL SUPPLEMENT 30 TO THE GENERICENVIRONMENTAL IMPACT STATEMENT FOR LICENSE RENEWAL OF NUCLEAR PLANTS,REGARDING THE LICENSE RENEWAL OF VERMONT YANKEE NUCLEAR POWER STATION DOCKET NO. 50-271Notice is hereby given that the U.S. Nuclear Regulatory Commission (NRC, Commission) has published a final plant-specific supplement to the "Generic Environmental Impact Statement for License Renewal of Nuclear Plants (GEIS)",NUREG-1437, regarding the renewal of operating license DPR-28 for an additional 20 years of operation for the Vermont Yankee Nuclear Power Station (Vermont Yankee). Vermont Yankeeis located in the town of Vernon, Vermont, in Windham County on the west shore of theConnecticut River.
Possible alternatives to the proposed action (license renewal) include noaction and reasonable alternative energy sources.As discussed in Section 9.3 of the final Supplement 30, the recommendation of the staffis that the Commission determine that the adverse environmental impacts of license renewal forVermont Yankee are not so great that preserving the option of license renewal for energy-planning decision makers would be unreasonable. The recommendation is based on: (1) the analysis and findings in the GEIS; (2) the Environmental Report submitted by Entergy; (3) consultation with Federal, State, and local agencies; (4) the staff's own independent review; and (5) the staff's consideration of public comments. The final Supplement 30 to the GEIS is publicly available at the NRC Public Document Room(PDR), located at One White Flint North, 11555 Rockville Pike, Rockville, Maryland 20852, or from the NRC's Agencywide Documents Access and Management System (ADAMS). The ADAMS Public Electronic Reading Room is accessible at http://adamswebsearch.nrc.gov/dologin.htm. The Accession Numbers for the final Supplement30 to the GEIS are ML072050012 for Volume 1, Main Report, and ML072050013 for Volume 2, Appendices. Persons who do not have access to ADAMS, or who encounter problems in accessing the documents located in ADAMS, should contact the NRC's PDR reference staff by telephone at 1-800-397-4209, or 301-415-4737, or by e-mail at pdr@nrc.gov
