Kaena Point STS is located on the northwestern tip of Oahu. The installation occupies approximately 153 acres of land and is situated on the ridge of the Waianae mountain range, approximately 47 miles from Honolulu. Kaena Point STS was established in 1958. The facility was initially operated to support the Discoverer Satellite Program and included antennas for acquisition, telemetry reception, and space vehicle command. Through the years, the installation has also supported other Department of Defense (DoD) space programs, including a satellite communications network, the Missile Detection and Alarm System, the Satellite and Missile Observation System, and the North American Aerospace Defense command. Currently, the land is being leased from the State of Hawaii and private landowners for Kaena Point STS by the 50th Space Wing of the Air Force Space Command. The station is currently managed and operated by Detachment 3, 21st Space Operations Squadron, Space Delta 6, Space Operations Command, U.S. Space Force (USSF).

Site ST-01 had a release of diesel fuel from a fuel system in 1972. The site included an oil-water separator and a cesspool, which were removed and decommissioned in 2011. The Hawaii Department of Health (HDOH) Hazard Evaluation and Emergency Response (HEER) Office concurred with the No Further Action (NFA) decision for the site in 2011 and required that an Environmental Hazard Management Plan (EHMP) be prepared to manage remaining contamination.

The IRP, in coordination with the HDOH, will consider all information submitted during the 30-day comment period associated with the FYR for Site ST-01.
