OC Health Care Agency (HCA) Comments on the City of Tustin Navy North Hangar Post-Fire
Action Summary Report and the Draft Hangar 1 Emergency Response Completion Report
Dear Scott Anderson,
The OC Health Care Agency (HCA) has completed its review of the following documents:
• City of Tustin’s Navy North Hangar Post-Fire Action Summary Report, Former Marine Corps
Air Station Tustin, California, dated June 3, 2026 (“Navy North Hangar Post-Fire Action
Summary Report”); and
• NAVFAC’s Draft Hangar 1 Emergency Response Completion Report, Former Marine Corps Air
Station Tustin, Tustin, California, dated March 31, 2026 (“Hangar 1 Emergency Response
Completion Report”).
The HCA’s consolidated comments on these reports are provided below.
Comments on the Hangar 1 Emergency Response Completion Report
The HCA has reviewed the Hangar 1 Emergency Response Completion Report and has no
technical or substantive comments to provide.
However, the HCA requests one administrative correction for consistency:
• The correct abbreviation for the OC Health Care Agency is “HCA.” Any reference to
“Orange County HCA” should be replaced accordingly.

Comments on the Navy North Hangar Post-Fire Action Summary Report
The HCA has also reviewed the Navy North Hangar Post-Fire Action Summary Report and
offers the following comments:
1. Acknowledgment of Expanded Supporting Documentation
The HCA appreciates the comprehensive updates, including the expanded details on
observed conditions, mitigation measures, and supporting documentation such as
community sampling results and progress updates. These improve the clarity of the
report and strengthen understanding of the response and protective measures
taken.
2. Minor edit Section 4.6 (Page 23)
The HCA recommends a minor word adjustment in the first sentence of Section 4.6
to improve accuracy:
“On December 23, 2023, the HCA hosted an informational webinar for the
community comprised of…”
3. Use of Correct Agency Abbreviation
As noted above, the HCA requests that all references to the agency utilize the correct
and standard form: “HCA.”
The HCA appreciates the opportunity to review and comment on both reports. Based on the
information presented in the Navy North Hangar Post-Fire Action Summary Report and the
Hangar 1 Emergency Response Completion Report, the HCA supports the City of Tustin’s formal
discontinuance of the local emergency for the North Hangar fire cleanup.
