W. M. Keck Observatory takes its responsibility for good stewardship of Maunakea very seriously. That’s why we are deeply committed to full transparency for our staff and our community as we work to understand how, why, and to what extent a small amount of oil has been seeping from our hydraulic system onto the pier that supports the Keck I telescope at our Maunakea facility.
We confirmed the presence of what we assume is hydraulic oil in the cinder directly beneath the telescope on June 4, 2018, and immediately reported it to the Hawaii Department of Health. We are cooperating fully with all appropriate authorities, including the Department of Health, the Department of Land and Natural Resources and the Office of Maunakea Management. And we have launched our own investigation, which will be overseen by independent environmental consultants Masa Fujioka and Associates.
We will post updates to this page as our investigation proceeds and our response plan is formulated. We are ready to answer any questions you may have, so please contact Mari-Ela Chock at firstname.lastname@example.org.

Since the formation of our internal investigation task force in May, conducting a rigorous exploration of possible releases of hydraulic oil to the environment from our hydrostatic bearing systems (HBS) has been W. M. Keck Observatory’s top priority.
Much progress has been made.
On June 7, Masa Fujioka and Associates (MFA), a third-party environmental, geotechnical, and hydrogeological consulting and engineering firm that Keck Observatory hired, conducted a site reconnaissance, and we know now the full extent of the release at our facility.
The investigation revealed that the total release includes a small amount of seepage coming from an oil return line located a few feet away from the Keck II pier; this seepage was also immediately contained.
We will continue executing preventative measures for all seepage locations as we work with the Hawaii State Department of Health and the Office of Maunakea Management to determine next steps.
MFA continues to conduct its independent investigation and analysis, and we are providing them with additional data needed to complete their assessment.
Following an initial consultation with HDOH, and with MFA’s guidance, MFA is preparing an Environmental Hazard Evaluation (EHE) and Environmental Hazard Management Plan (EHMP) on behalf of Keck Observatory, as required by HDOH HEER office’s Technical Guidance Manual.
We remain committed to working in accordance with HDOH and are giving this investigation the full attention it requires as the observatory’s top priority.

In order to give the Department of Land and Natural Resources (DLNR) and Office of Maunakea Management (OMKM) full visibility into our pier oil investigation, representatives of both organizations visited our summit facilities on Aug. 1 for an in-person site inspection.
The visit was thorough, giving the oversight agencies a chance to get a first-hand look at the seepage and containment measures in place to ensure no further hydraulic fluid can reach the ground.
Bob Masuda, DLNR’s First Deputy, spoke with reassurance that Keck Observatory’s ongoing efforts are on the right track.
“We appreciate Keck’s openness and transparency in dealing with this technical issue,” said Masuda. “Personal inspection and on-site briefing provided clear comprehension of the issue and seepage remediation. Keck has and is doing things right, reporting directly in a timely manner, applying highly professional response, and dealing with things forthrightly.”
