Enhanced Integrated Air & Missile Defense (EIAMD) System on Guam

The Missile Defense Agency (MDA), as the lead agency, and the U.S. Army, as a cooperating agency, jointly issued a Record of Decision (ROD) to implement the construction, deployment, and operations and maintenance of the Enhanced Integrated Air and Missile Defense (EIAMD) system on Guam. The action will enable MDA and the U.S. Army to meet their congressional mandate for a persistent 360-degree layered Integrated Air and Missile Defense capability on Guam to address the rapid evolution of missile threats from regional adversaries. In addition to the U.S. Army, the U.S. Air Force, U.S. Navy, and Federal Aviation Administration participated as cooperating agencies in the development of an Environmental Impact Statement (EIS) due to their jurisdiction or special expertise as it pertains to certain components of the action or for potentially affected operations and resources.

In compliance with the National Environmental Policy Act (NEPA) and other applicable federal laws, MDA and the U.S. Army prepared the Final EIS, which includes an analysis of the potential environmental impacts from the construction, deployment, and operations and maintenance of the EIAMD system to defend Guam, as well as responses to public comments on the Draft EIS.

The MDA and the U.S. Army selected the Proposed Action after considering the need for the system, the potential environmental impacts, and comments received from elected officials, government agencies, nongovernmental organizations, and the public. Mitigation measures that avoid, minimize, or mitigate potential environmental impacts will be employed.
