For the first time in nearly 60 years, Benicia’s refinery stacks have gone quiet as Valero has officially stopped refining at the plant, general manager and vice president, Lauren Bird, confirmed Tuesday.

About 60 employees are expected to remain at the Benicia refinery following another round of layoffs Wednesday — a fraction of the roughly 400 employees once employed at the refinery.

Bird said about 20 employees will ultimately be left at the facility after the layoffs conclude. These workers — alongside contractors — will help Valero continue importing, storing, and distributing gasoline and diesel fuel, Bird said.

Valero will no longer supply jet fuel through Benicia, said the company’s section business law chief, David Giles. The amount of petroleum products distributed will be roughly a third of the more than 100,000 barrels that were previously refined daily at the plant.

Bird is retiring at the end of the month. Valero has been tight lipped about their future plans. Bird and executives from San Antonio spoke at the final meeting of the Valero Community Advisory Panel on Tuesday. Although the community advisory panel will cease to exist, the city and Valero may continue discussions through other existing committees, such as the city’s Industrial Safety Citizen Oversight Commission.

The Benicia refinery was originally built in 1968 by Humble Oil Company, which was acquired by Exxon Mobil in 1973. Valero purchased the refinery from Exxon Mobil in 2000 for $895 million.

Valero aims to leave entirely in two years

Valero executives dashed any hopes that the company might pursue a “tank farm,” or longer-term storage at the facility. Instead, Valero is likely to vacate the site in the next two years, according to Giles.

“We use that word, ‘idle,’ because the State of California has asked to idle the refinery in a state where it could theoretically be restarted,” Giles said. “Valero doesn’t have an intention to do that … but we’re keeping that [infrastructure] in place at their request. We’re not going to do that forever…It could be more than a year, but we don’t see going more than a couple of years, and probably less.”

Benicia faces tough budget cuts

The closure of Valero could result in up to nearly $11 million in annual revenue loss, largely in lost tax and water utility payments, according to the city’s worst-case projections. But the city cannot yet forecast when and how its tax base will be hit by Valero’s decision to idle its refinery, said City Manager Mario Giuliani, speaking at the recent State of the City address.

Giuliani said the city only expects to get clarity on the true cost of Valero’s exit in early 2027. Meanwhile, he said the city will use about $3.5 million of reserves in the next year to cover anticipated shortfalls from lost revenue. The city manager warned that Benicians can expect to make tough cuts in services in the town’s next 2027-2029 budget cycle.

The city continues to eye ways to bridge the financial gap, including applying to access at least $25 million in earmarked funding stemming from Valero’s payment to the Bay Area Air District of its 2024 record-setting pollution fine.

Dr. Richard Fleming: Public Health Risks of Tank Farms

The health problems caused by refineries are well-established. What about tank farms?

With the Valero refinery shutting down, a number of options are being considered for what to do with the property. One possibility is turning the location into a “tank farm,” a place which stores petroleum products in massive tanks. The health problems caused by refineries are well-established. But what are the health risks of tank farms? Are there reasons we should be worried about a tank farm being set up in our city? And should our city government be concerned about the possible public health impact of a tank farm replacing the refinery?

Good studies have been done looking at the potential health risks of tank farms. While they tend to be a bit less harmful to surrounding communities than refineries, they do present potential health problems we should all be aware of.

The two major areas of concern with tank farms are the risks they can send toxic chemicals into the air and the potential they can leak toxic materials into the land they sit on and into nearby groundwater systems. Let’s look briefly at each problem.

Emissions. Oil storage tanks produce emissions of volatile organic compounds (VOCs), including benzene, toluene, ethylbenzene, and others. Many of these chemicals are carcinogenic. As is true of refineries, when these emissions enter the air, they have an adverse impact on surrounding communities.

How do dangerous emissions happen at tank farms, given that they are just large tanks storing petroleum products? One of the main ways happens when additional oil or gasoline is being pumped into a partially filled storage tank. This inevitably leads to the densely-concentrated vapors inside the tank being pushed out into the air. These emissions are full of toxic VOCs. VOCs can also be emitted during pumping itself, as well as through leaking seals, vents, and fittings in the tanks themselves. It is impossible to guarantee that tanks will never have any possible breaches leading to toxic emissions.

Chemical leakage. Various factors can lead to the petroleum-based liquids stored in tanks leaking into surrounding soil and water. Corrosion of tank walls can create leaks, and these can be hard to detect until significant outflow has already occurred. Operational errors during filling or draining procedures can lead to leaks. Defective welds can leak.

Natural disasters like flooding and earthquakes can lead to massive leaks. The Valero property is at significant risk of flooding during massive storms, and these seem to be happening more frequently every decade. Sea level rise itself also puts the Valero property at risk of flooding, especially since some of the land is at or  below sea level. And we all know that our state is at risk for major earthquakes.

The risk from leakage into groundwater is especially concerning because, according to the Environmental Protection Agency, one gallon of gasoline can contaminate one million gallons of water.

So what is the take-home message? Establishing a tank farm on the Valero property would likely be somewhat less risky for public health than an operating refinery, but tank farms still pose major potential problems for Benicians and nearby communities. Since there are many other uses which could be developed on the Valero property after it is cleaned up, why not move towards safer development?

March 26 refinery injuries being investigated…

By Monica Vaughan, Excerpt from the Benicia Bridge Newsletter, April  10, 2026

NBC reported that two dozen workers went to the emergency room with burns when black liquid rained down on them for about five minutes from the flare stack incident on March 26. Cal-OSHA is investigating. A quick review of OSHA records show this is the second investigation into worker safety opened at the facility this year. Last year, Valero racked up at least 11 violations amounting to $80,000 in penalties for worker safety violations at the Benicia refinery. Valero is contesting the findings.

City Council receives 43-page report, ‘Port of Benicia – Facilities and Infrastructure Modernization Plan’

By Monica Vaughan, The Benicia Bridge, April  10, 2026

Benicia City Council learned about improvements needed to maintain the Port of Benicia, as well as potential work that could attract more seafaring customers – to the cost of $700 million.

Background: The City of Benicia received a $750,000 grant to develop a Port of Benicia Facilities and Infrastructure Modernization Plan. The consultant doing the work, GHD, presented parts of the plan to councilmembers at a city council meeting Tuesday. The grant came from regional government agencies, the Metropolitan Transportation Commission and the Association of Bay Area Governments.

The main takeaways: The port and surrounding area need work to maintain operations into the near future, like structural improvements to the pier, stormwater infrastructure, and nearby roads and intersections used by truck traffic related to port activities.

Long-term work is needed to build up the seawall to protect against sea-level rise. And, there are opportunities to expand the pier to allow for additional moorings.

The total cost of all projects reviewed is around $700 million. The council may consider going after grants to help tackle some or all or none of the projects suggested.

Council members seemed dubious about investments, given that the port is privately owned and operated by AMPORTS. As Councilmember Trevor Macenski put it, “Would you spend $700 million on capital projects supporting an industry that doesn’t significantly benefit the city?”

Councilmember Kari Birdseye noted that AMPORTS is a big company in our community, but urged that work moving forward, especially grant opportunities, “has to benefit the larger community and not just one company in our city.”

The consultant suggested the city consider the benefits of a public/private partnership, and noted that other cities work hard to attract a company like AMPORTS to invest in infrastructure that could bring additional industry and revenue to the area.

“At least you have a partner with a revenue stream,” Vanderbeek said.

The reports provided, however, do not include market research or outreach to other potential customers who could bring business to the port.
