A DEA is required under Hawaiʻi’s environmental laws for proposed uses of state lands or funds and uses within the state conservation district. The Hōkū Keʻa decommissioning plan reviewed in the DEA includes the safe and proper removal of two buildings and supporting infrastructure, and restoration of the site to its original state, as much as possible.
After the DEA process is complete, the Department of Land and Natural Resources will process and issue a conservation district use permit for the proposed actions. The project is tentatively scheduled to be completed by late 2023, and the site will not be used for astronomy purposes again.
Hōkū Keʻa is one of two Maunakea telescopes in the process of being decommissioned.
