Welcome to the U.S. Army’s website for the Terminal High-Altitude Area Defense (THAAD) Permanent Stationing in Guam Environmental Assessment (EA). This website is the U.S. Army’s online center for the public to learn information about and become involved in the THAAD EA process. The EA was previously released for public comment in June 2015. Because of changes to the overall size of the cargo drop zone training area and associated vegetation clearing, and the completion of agency consultations for biological and cultural resources, the updated EA and associated Draft Finding of No Significant Impact (FNSI) were re-released for public comment in March 2017. The public comment period for the EA and Draft FNSI ended on April 17, 2017. The Final EA and signed FNSI will be posted to the "Documents" page of this website when available.
