Welcome to the Department of the Navy's website for the Supplemental Environmental Impact Statement (SEIS) for the "Guam and CNMI Military Relocation; Relocating Marines from Okinawa, Japan to Guam."

The Department of the Navy has signed the Record of Decision (ROD) for relocating U.S. Marine Corps forces to Guam.

The Department of the Navy selected the preferred alternatives as described in the Final Supplemental Environmental Impact Statement (SEIS). This includes cantonment and family housing Alternative E with the USMC cantonment to be located at Navy Computer and Telecommunications Station – Guam (Finegayan), and family housing to be located at Andersen Air Force Base. The Live Fire Training Range Complex (LFTRC) option selected was Alternative 5 to be located at Andersen Air Force Base – Northwest Field. The LFTRC also includes a stand‐alone hand grenade range at Andersen South.

This action will ensure consistency with the new force posture adopted by the Department of Defense in accordance with the April 2012 Roadmap Adjustments’ international agreement. This ROD provides for a smaller force on Guam than originally was proposed in the 2010 Final EIS, while fulfilling U.S. national security interests in the Western Pacific.

Download a copy of the ROD here on the SEIS website (, or review a hardcopy either at the Robert F. Kennedy Memorial Library located in the University of Guam or the Nieves M. Flores Memorial Library in Hagatña.
