(City of Tustin, CA – January 30, 2024) – The City of Tustin announced today that an informational webinar will be posted online on January 31 describing the methodology and implementation plan for the exterior soil and interior air/dust sampling study following the Navy North Hangar Fire.
The webinar will be available online at 3 pm PT on Wednesday, January 31 at Exterior Soil & Interior Air/Dust Study Informational Webinar.
The study will assess the potential impact of the Navy’s North Hangar Fire on the surrounding community and has received approval from County, State, and Federal Regulators including the U.S. Environmental Protection Agency (US EPA), California Department of Toxic Substances Control (DTSC), South Coast Air Quality Management District (SCAQMD), the Orange County Health Care Agency (OCHCA), CTEH and the U.S. Navy.
“I want to thank County Health Officer, Dr. CK, and her staff for their support throughout the incident. Like many of my neighbors, I was relieved by the OCHCA announcement that airborne asbestos has never been detected during the entirety of the incident,” Mayor Austin Lumbard said.
“However, we understand the community’s lingering concerns and we are committed to going above and beyond what may be scientifically required to assure that our residents feel safe in their own homes,” Lumbard said.
The study, which will be conducted by environmental experts from Geosyntec Consultants, will test 50 randomly selected residences in the vicinity of the Navy North Hangar site for the presence of lead and asbestos related to the fire in residential soil, household dust, and interior air. These results will be compared to 30 randomly selected residences located outside of the fire impact area in Santa Ana and Irvine to look for differences potentially related to the Navy’s Hangar Fire.
Mailers will be sent out beginning this week to residents who are interested in signing up for the study before the deadline of February 14, 2024. Residences randomly selected for the study will be contacted by email in late February to schedule a date and time for the sampling.
The results will be reviewed by the EPA, SCAQMD, and OCHCA. Study results are expected to be available in late April 2024 pending review by the regulatory agencies.
Geosyntec Consultants has over 30 years of experience in addressing post-fire conditions and has been involved in community sampling studies related to the Aliso Canyon natural gas leak, the USS Bonhomme Richard fire in San Diego, the Fort McMurray wildfire in Alberta, Canada, the 2003/2007 Southern California wildfires, the 2015 Butte and Valley wildfires, and the 2021 Dixie wildfire.
The U.S. EPA has deemed the U.S. Navy the responsible party for the releases from the Navy North Hangar Fire.
