Welcome to the AMOS STAR Facility EIS Website
Welcome to the website for the Department of the Air Force (DAF) Environmental Impact Statement (EIS) for the proposed Air Force Maui Optical and Supercomputing Site Small Telescope Advanced Research (AMOS STAR) Facility in Maui, Hawaii. The project proponent is the 15th Space Surveillance Squadron, a blended asset unit with personnel from the U.S. Space Force Combat Forces Command and the Air Force Research Laboratory.
Under the National Environmental Policy Act (NEPA), the DAF must analyze the environmental and socioeconomic effects of any proposed major federal action, evaluate alternatives, and provide opportunities for public and stakeholder participation. The NEPA process began in April 2024 with publication of the Notice of Intent to prepare an EIS in the Federal Register. Scoping meetings in May 2024 provided information about the proposed AMOS STAR project and solicitated comments from stakeholders on issues to be considered in the Draft EIS.
The AMOS STAR EIS was initially being developed in accordance with the Hawai`i Environmental Policy Act (HEPA) (Hawai`i Revised Statutes [HRS] Chapter 343) and Hawai`i Administrative Rules (HAR) (§11.200.1) as well as NEPA because a proposed new utility easement would have involved the use of state land within the State Conservation District (HRS § 343-5(a)(1) and (2)). However, through the evolution of the project design, the Proposed Action no longer triggers the applicability of HEPA.
The Draft EIS comment period began with publication of the Notice of Availability (NOA) in the Federal Register on January 30, 2026. Draft EIS public hearings were held on Maui on February 17 and 18, 2026. Following a 30-day extension, the public comment period closed on April 15, 2026.
The Final EIS and ROD will be available soon.
