RECOMMENDATIONS ON THE EXTERIOR TOP-DOWN INSPECTION
EVIDENTIARY PACKAGE, TUSTIN NORTH HANGAR FIRE, FORMER MARINE
CORPS AIR STATION TUSTIN, TUSTIN, CALIFORNIA
Dear North Hangar Fire Environmental/Health Unit:
The Department of Toxic Substances Control (DTSC) has reviewed the Exterior Top-
Down Inspection Evidentiary Package (Report) dated February 16, 2024, that was
presented and discussed at the North Hangar Fire Environmental/Health Unit
Operations meeting held on February 20, 2024.
The inspection effort was conducted by IEM, Inc. and ATI, contractors for the City of
Tustin, at the request of the South Coast Air Quality Management District (SCAQMD)
and the United States Environmental Protection Agency on January 26, 2024, to assess
the extent of above ground fire-related debris and for evaluation of potential future
recontamination by such debris.
The Report presented information on the initial post-fire remediation efforts and results
of a reinspection effort that took place between January 26-31, 2024, that focused on
above ground structures, such as roof tops and gutters, in areas impacted by the North
Hangar Fire incident. The Report identified the presence of suspected asbestos
containing material (ACM) and possible fire-related debris.

Based on DTSC’s review of the Report, it is apparent that fire-related debris and
suspected ACM still exists on above-ground structures. DTSC acknowledges that while
fire-related debris and suspected ACM may have been previously mitigated, ongoing
mitigation of debris may be required to ensure that remaining debris is recovered
appropriately.
DTSC recommends that an implementation plan be developed to remove remaining
debris on above-ground structures as a proactive measure to prevent future
reoccurrence of impacts from these materials.
