Contra Costa supervisors approve transfer of hazardous-materials unit; commissioners and residents urge briefings and safeguards

Contra Costa County's Board of Supervisors has voted to transfer the county's Hazardous Materials Division from Contra Costa Health to the Contra Costa County Fire Protection District, a move that commission staff and community members say requires further explanation and safeguards.

Nicole Heath, director of hazardous materials programs, told the Hazardous Materials Commission that the board —did vote unanimously to transition the division over from the health department over to the fire department.— She said the board order considered an effective date of Jan. 1, 2026, but that date has not been finalized and a transition would likely take at least a year or more to complete.

Why it matters: The transfer shifts administrative oversight of hazardous-materials work into the fire district, prompting questions about continuity of public-health review, community participation and long-term monitoring of chronic emissions. Residents and several commissioners worried the move could reduce the health-department role in non-emergency public-health assessments.

At the meeting, public commenter Charles Davidson of the Sunflower Alliance and the Rodeo Citizens Association urged the commission to preserve health oversight. —Fire departments excel at acute emergency response, but how will this translate to addressing chronic health concerns like ongoing particulate matter emissions or incessant flaring?— he asked, proposing a dual-authority model that would keep the health department's regulatory oversight while integrating Con Fire for operational emergency response.

Several commissioners, including Maureen Brennan (environmental justice seat), described the announcement as a surprise. —I am very disturbed by this possible transition,— Brennan said, calling for more transparency about how and why the board acted before the commission had an opportunity to advise.

What staff said: Heath said many implementation details remain to be worked out. She told the commission the division's physical location would remain at 4585 Pacheco Boulevard, most division staff would transfer (the integrated pest-management coordinator was identified as an exception) and that current staff who support board committees would remain assigned to those committees after the organizational move. She also said the division currently has four vacancies and that two of those positions are actively being posted.

On labor and response capacity, Heath said the conversation began with labor interest in potential efficiencies and that combining response teams was one of the Fire Chief's points. She described a plan in which existing hazmat response teams would be consolidated; Contra Costa Fire currently fields about 45 personnel for its hazmat response team and, the chief has said, is looking to expand that number.

Next steps: Commissioners decided to request a briefing that includes both Contra Costa Fire and Contra Costa Health so members can ask questions directly and decide whether to send a formal letter to the Board of Supervisors. Heath said the public's role and many other details would be addressed during the transition planning but that the commission's request for additional information would be appropriate.

The commission did not vote on any formal recommendation at this meeting. The board order and the Fire Chief's presentation were cited as the Board's basis for the action.
