DEPARTMENT OF DEFENSE

Office of the Secretary


Notice of Availability of the Final Environmental Impact 
Statement for the Enhanced Integrated Air and Missile Defense System on 
Guam

AGENCY: Missile Defense Agency (MDA), Department of Defense (DoD).

ACTION: Notice of availability (NOA).

-----------------------------------------------------------------------

SUMMARY: The MDA, as the lead agency, has prepared a Final 
Environmental Impact Statement (EIS) for the Enhanced Integrated Air 
and Missile Defense (EIAMD) System on Guam. The United States (U.S.) 
Army (USA), U.S. Navy (USN), U.S. Air Force (USAF), and the Federal 
Aviation Administration (FAA) are cooperating agencies in the 
development of the Final EIS. The Final EIS includes an analysis of the 
potential environmental impacts that may result from the Proposed 
Action to construct, deploy, and operate and maintain the EIAMD system 
to defend Guam against advanced missile threats. The Final EIS was 
prepared in compliance with the National Environmental Policy Act and 
in accordance with MDA, USA, USN, USAF, and FAA's implementing 
procedures. The procedures followed in the development of the Final EIS 
also supports compliance with the National Historic Preservation Act of 
1966 and its implementing regulations.

DATES: The MDA and USA will not issue a final decision on the proposed 
action until 30 days after the date that the U.S. Environmental 
Protection Agency (USEPA)-issued NOA is published in the Federal 
Register.

FOR FURTHER INFORMATION CONTACT: Mr. Mark Wright, MDA Public Affairs, 
at 571-231-8212, or by email: mda.info@mda.mil">mda.info@mda.mil. For more information, 
including a downloadable copy of the Final EIS, visit the MDA website:

SUPPLEMENTARY INFORMATION: A Notice of Intent to prepare an EIS was 
published in the Federal Register on May 5, 2023, which provided 
information about the public scoping period, how to submit public 
scoping comments, and the close of the public scoping period on June 
27, 2023. A Notice of Scoping Comment Period Extension was published in 
the Federal Register on June 9, 2023, announcing the extension of the 
comment period to August 11, 2023, in response to ongoing Typhoon 
Mawar-related recovery efforts. The notice also stated that open house 
public scoping meetings would be rescheduled. A second Notice of 
Scoping Comment Period Extension was published in the Federal Register 
on July 21, 2023, announcing another extension of the comment period to 
August 18, 2023, and the rescheduled open house public scoping meetings 
dates. MDA published a Draft EIS NOA (89 FR 85523) in the Federal 
Register on October 28, 2024, and USEPA published a Draft EIS NOA (89 
FR 85200) in the Federal Register on October 25, 2024, which provided 
notice that the Draft EIS (EISX-007-20-MDA-1725955966) was available 
for public review and comment from October 25, 2024, to January 8, 
2025.
    The MDA held two Draft EIS public meetings on November 14, 2024, 
and November 15, 2024, to inform the public and stakeholders about the 
Proposed Action and the findings of the EIS, answer questions, and 
solicit comments on the Draft EIS and the project's potential to affect 
historic properties.
    The public was able to submit comments via an electronic comment 
form on the project website, via email, in person at the public 
meetings (written or oral via a court reporter), or via U.S. postal 
mail. The MDA received 72 comments during the Draft EIS public review 
and comment period. Comments on the Draft EIS were considered, 
incorporated, and responded to as appropriate into the Final EIS. 
Comments resulted in the addition of clarifying text and updated 
information.
    Within the context of homeland defense, Guam is a key strategic 
location for sustaining and maintaining U.S. capabilities, deterring 
adversaries, responding to crises, and maintaining a free and open 
Indo-Pacific. As a U.S. territory, an attack on Guam would be 
considered a direct attack on the U.S. and would be met with an 
appropriate response. Currently U.S. forces are capable of defending 
Guam against today's regional ballistic missile threats. However, 
regional missile threats to Guam continue to increase and advance 
technologically. U.S. Indo-Pacific Command identified a requirement for 
a 360-degree EIAMD system on Guam as soon as possible to address the 
rapid evolution of adversary missile threats.
    In the Final EIS, MDA, in coordination with cooperating agencies, 
evaluated the potential environmental impacts associated with the 
Proposed Action as well as a No Action Alternative. The Proposed Action 
is to construct, deploy, and operate and maintain a comprehensive, 
persistent, 360-degree EIAMD system to defend the people, 
infrastructure, and territory of Guam against the rapidly evolving 
threats of advanced cruise, ballistic, and hypersonic missile attacks 
from regional adversaries. The proposed system includes a combination 
of components from MDA, USA, and USN that would be integrated for air 
and missile defense. These components include missile defense radars, 
sensors, missile launchers and missile interceptors, and command and 
control systems.
    The MDA and USA need to strategically locate and integrate the 
various system components at multiple sites around Guam. The MDA and 
USA identified 16 proposed sites to operate and maintain the EIAMD 
system on DoD properties on Guam. A limited number of the proposed 
sites would require real estate actions on non-DoD properties for 
access, or where safety zone arcs encroach on non-DoD properties. If 
the decision is made to proceed with the Proposed Action, site 
preparation and construction would span approximately 10 years 
beginning in 2025. The EIAMD operational capability would be phased in 
as each site completes construction, testing, and final system checks 
of the installed components. Following final construction, testing, and 
final system-wide checks, the EIAMD system would become fully 
operational.
    The MDA and cooperating agencies analyzed the potential direct and 
indirect impacts the Proposed Action may have on airspace management, 
health and safety, cultural resources, terrestrial biological 
resources, socioeconomics, protection of children, land use and 
recreation, transportation, visual quality, utilities, air quality, 
greenhouse gases, noise, water, and geology and soils. Mitigation 
measures that could avoid, minimize, or mitigate potential 
environmental impacts of the Proposed Action are also proposed in the 
Final EIS.
    The MDA invites all interested members of the public, as well as 
Federal and territorial agencies, to view the Final EIS. The Final EIS 
is available on the MDA public website at www.mda.mil/system/eiamd and 
at the following public libraries: (1) University of Guam Robert F. 
Kennedy Memorial Library, UOG Station, Mangilao, Guam 96913; (2) Nieves 
M. Flores Memorial Library, 254 Martyr St., Agana, Guam 96910.
    The Missile Defense Agency's National Environmental Policy Act 
(NEPA) Implementing Procedures, Para. 4.(c) (August 8, 2014) (79 FR 
46410) allow for the publication of notices in the Federal Register for 
draft and final NEPA documents. These procedures outline how the 
Missile Defense Agency complies with the National Environmental Policy 
Act (42 U.S.C. 4321 et seq.).
