Call to Action

TMT has no future in Hawaiʻi

Updated October 2, 2026

UH is proposing revisions to their Maunakea Master Plan that prioritizes the reuse of decommissioned sites, creating a way to build TMT on Mauna Kea.

MKSOA is having a meeting on October 8, 2026 and the UH Master Plan revisions are on the agenda as item VIII.A.

Review the proposed amendments in the document here.

Sample Testimony

I oppose the UH’s blatant attempt to amend the 2022 Master Plan for the sole purpose of erroneously assuring TMT partners that this massive project can still be built on Mauna Kea.

This proposal is not in compliance or alignment with the BLNR and BOR approved management plans. UH is clearly reneging on itʻs commitments made to the public of not constructing on decommissioned sites.

This action undermines MKSOA. These revisions should be rejected to allow MKSOA to lead the planning process through meaningful community engagement and transparent governance with Native Hawaiian cultural processes and values as outlined in Act 255. 

This proposal to amend the master plan is pointless, given the restrictions on UH's ability to amend or issue new leases and adds to the community's distrust of the UH system which, once again, is not hearing the community's voices.

Above is an example to copy and paste, but please consider personalizing your testimony. Here are some prompts you can answer to include in your testimony:

  • What Mauna Kea means to you and why it should be protected

  • Concerns about the proposed changes to allow building an observatory on a previously disturbed (decommissioned) site

  • What you want MKSOA to prioritize in managing, protecting, restoring, and stewarding Mauna Kea for future generations

other talking Points

  • UH should not establish policies that predetermine decisions belonging to MKSOA.

  • Preserve MKSOA’s ability to restore astronomy sites and land.

  • Evaluate cultural resources, environmental protection, restoration and land use as a whole comprehensive management issue.

  • Ensure Mauna Kea’s Indigenous management principles and cultural practices are central to MKSOA’s decisions.

  • These are long-term policies that should be established through MKSOA’s own management framework.

  • Reject or defer the amendments and allow MKSOA to lead the planning process through meaningful community participation and transparent governance.

  • UH is attempting to alter land-use policies right before its management expires, which undermines MKSOA.

Concerning MKSOA:

  • Mauna Kea deserves meaningful participation from Native Hawaiians.

  • Native Hawaiian cultural processes and values should influence the actual land use decision.

  • A decommissioned site should mean full environmental and cultural restoration and should revert to protected, undeveloped land, not remain classified as “developed” for future projects.

  • Decommissioned sites should first be evaluated for restoration.
