Air District will require Valero to expand fenceline monitoring program after “significant incidents” that polluted surrounded community, including a gasoil release in Dec. 2021

The settlement resolves 118 notices issued by the air pollution regulator for violations that occurred between 2019 and 2023, according to Kristine Roselius, a spokesperson for the Air District. In addition to the penalty, Valero will be required to expand its fenceline air quality monitoring program, and provide public access to and reporting of the monitoring data.

[BenIndy Editor: The following is excerpted from part 1 of a Stephen Golub interview of Benicia Fire Chief Josh Chadwick as it appeared in the Benicia Herald today, April 26. The whole interview is interesting , but especially so at the end when addressing Benicia’s Industrial Safety Ordinance (ISO) and the idling and transition of Benicia Valero Refinery.]
Stephen Golub interview with Chief Chadwick: the ISO & Valero as it transitions to a tank farm

By Stephen Golub, The Benicia Herald, April 26, 2026
GOLUB: You played a large part in crafting Benicia’s Industrial Safety Ordinance, which was adopted by the City Council last year. When you first started as a firefighter, did you have any expectations that you could end up doing anything like that?
CHADWICK: Firefighters are trained in hazardous materials response. We are also training in air monitoring, which is the realm of confined space rescue. But being asked to develop an Industrial Safety Ordinance is not the norm. I have good working relationships with many other fire chiefs, and none of them deal with this issue
GOLUB: Particularly given that the ISO’s implementation has been affected by Valero’s decision to idle the refinery, do you have any thoughts on how that implementation is going? Any thoughts on its implementation or challenges going forward?
CHADWICK: Overall, the implementation is going well. I understand there may be some in the community who would like to see more visible progress, but significant work has been happening behind the scenes. This is a new program for Benicia, so there is naturally a ramp-up period.
We also didn’t truly get started until after the ordinance development process was complete. It was approved by the council in April 2025, but it didn’t take effect for another 120 days, and finalizing the associated fees extended into December. So, in many ways, we’re still in the early stages of implementation.
The idling of the refinery has had more of an indirect impact. Historically, the periods of highest risk for incidents and flaring are during shutdowns und startups, so it was expected that taking the refinery offline would in involve some increased activity. And more broadly, it’s important to recognize that no level of regulation can completely eliminate the risk associated with large industrial operations.
GOLUB: In what ways might Valero’s idling the refinery make the BFD’s work easier? In what ways might it make the work tougher? How might the answers change if Gov. Newsom’s plan for the refinery to transition to becoming an oil storage terminal (“tank farm”) for fuel produced elsewhere goes through? Is it yet clear what will become of Valero’s on-site firefighting personnel and equipment once the facility transitions from a refinery to an oil terminal?
CHADWICK: There are a few different pieces to that.
From a firefighter’s perspective, if refining operations are idled, that generally reduces some of the more complex and high-risk processes we plan for. In general, there is a reduction in pressure and temperature. So, in that sense, it could simplify parts of the risk profile.
That said, it doesn’t eliminate the hazard. Whether it’s a refinery or a fuel terminal, you’re still dealing with large volumes of combustible and flammable liquids. A transition to a tank farm shifts the risk rather than removes it. More focus is on storage, transfer operations, and transportation components. Those come with their own set of challenges and fire protection considerations.
In terms of whether that makes the iob easier or tougher, it’s probably more accurate to say it makes it different. We would need to evaluate the specific operations and adjust our planning, training, and response accordingly.
As for on-site firefighting personnel and equipment, that’s not entirely clear yet. From our standpoint, maintaining a strong on-site fire protection capability is critical given the scale of the hazards, and that’s something we’ve been actively engaged in discussions about.
Swings will be installed at the Playground of Dreams on First Street in Benicia within the next six weeks. The historic wooden play structure at the downtown park requires major restoration work that won’t likely begin until 2030.

Swings are expected to return to downtown’s Playground of Dreams in the next six weeks. The new, donated equipment will be the first swings at the City Park in five years, said Dan Smith of the local nonprofit Benicia Friends of the Playground. Smith was speaking at Tuesday’s City Hall meeting.

March 26 refinery “material release” remains under investigation…

Valero delayed reporting the March 26 flare-tower “material release,” which remains under investigation by several agencies. The plant may not have reported the flaring to state authorities at all, had it not been for Solano County officials’ urging.
A distinctive black plume from one of Valero’s three flare stacks made local headlines in March. Unsure of what was being spilled into the air, Benicia Fire Chief Josh Chadwick issued a voluntary shelter-in-place warning for the city, as previously reported by The Benicia Bridge. NBC News reported that about two dozen Valero workers were sent to the hospital with chemical burns caused by cleaning chemicals involved in the incident. Company officials denied that happened.
