The Martinez refinery lawsuits are a cluster of civil and regulatory cases brought against Martinez Refining Company LLC, the PBF Energy subsidiary that runs the 157,000-barrel-per-day plant in Contra Costa County, California. They include a proposed residents’ class action in state court, four federal personal injury suits covering roughly 700 plaintiffs, a $10 million joint civil judgment from the county district attorney and the Bay Area Air Quality Management District, a $4.48 million Clean Water Act settlement with the regional water board, and a separate enforcement action tied to a February 2025 refinery fire that is still unresolved.1Bay Area Air Quality Management District.

What Triggered the Lawsuits
On Thanksgiving evening 2022, a malfunction at the refinery released an estimated 20 to 24 tons of “spent catalyst,” a metallic dust containing elevated levels of aluminum, barium, chromium, nickel, vanadium, and zinc, into the surrounding neighborhoods. The Bay Area Air Quality Management District identified a 15-mile area where the dust may have settled. The refinery did not notify Contra Costa Health or activate the Community Warning System, as required by law.3Contra Costa Health. Martinez Refining Company Oversight4ABC7 News. Martinez Refining Company Class Action Lawsuit
Testing later confirmed the dust contained heavy metals capable of causing respiratory problems, and the county advised residents against eating produce grown where the material had landed. Coke dust releases followed on July 11, July 22, and October 6, 2023, along with heavy flaring and a grass fire in December 2023. Contra Costa County Health documented at least 21 separate hazardous material releases or spills at the refinery during 2023.5Local News Matters.

The Residents’ Class Action
On November 28, 2023, Martinez residents Alena Cruz and Shannon Payne filed a proposed class action in Contra Costa County Superior Court against Martinez Refining Company LLC, PBF Energy Inc., and PBF Energy Western Region LLC. The complaint alleged the refinery had created a public nuisance through repeated chemical releases and had violated the requirement to alert the county health department and community warning system within 15 minutes of each incident.6CBS News.

Cruz, who said she had a pre-existing condition affecting her breathing, was concerned emissions would worsen her health. The suit asked the court to order the defendants to pay for medical monitoring so affected residents could be screened and treated for potential health effects from the toxic exposures.4ABC7 News. Martinez Refining Company Class Action Lawsuit A refinery spokesperson said the company does not comment on pending litigation. The company had earlier issued a public apology, said it was unaware of any public impact until the day after the Thanksgiving 2022 release, and said it had implemented corrective actions.6CBS News.

The Federal Personal Injury Cases
The larger fight is in the U.S. District Court for the Northern District of California, where the firms Cutter Law and TorkLaw have filed four related mass-joinder personal injury suits.
The lead case, Frye, et al. v. Martinez Refining Company LLC (Case No. 3:24-cv-04506), was filed July 25, 2024, on behalf of 18 plaintiffs. It brings claims of negligence, public and private nuisance, premises liability, trespass, and strict liability for ultrahazardous activities, and alleges severe and permanent lung damage, cardiovascular and pulmonary disease, liver and kidney damage, nausea, and fatigue. Lead plaintiff Jennifer Frye reported being on supplemental oxygen around the clock as a result of toxic dust exposure.2Cutter Law. Martinez Refining Company Toxic Exposure Litigation7PR Newswire. TorkLaw and Cutter Law File Major Lawsuit Against Martinez Refinery
On December 16, 2024, U.S. District Judge Rita F. Lin granted the company’s motion to dismiss in part and denied it in part. Most claims were allowed to proceed. The court ruled that whether petroleum refining qualifies as an ultrahazardous activity is a factual question that cannot be resolved at the pleading stage, and it found the plaintiffs had plausibly alleged “despicable conduct,” including failure to maintain emission controls and failure to notify the public promptly, sufficient to support a claim for punitive damages. Two plaintiffs were given leave to amend their negligence and trespass claims after the court found they had not adequately linked their specific symptoms to the chemicals released.8Cutter Law.

Three additional complaints followed in November 2024, together adding roughly 700 plaintiffs:
- Saliba, et al. v. Martinez Oil Refining Company LLC, filed November 19, 2024, with 285 plaintiffs.
- Silvestri, et al. v. Martinez Oil Refining Company LLC, filed November 21, 2024, with 195 plaintiffs.
- Manning, et al. v. Martinez Oil Refining Company LLC, filed November 22, 2024, with 204 plaintiffs.2Cutter Law. Martinez Refining Company Toxic Exposure Litigation
All three were assigned to Judge Haywood Stirling Gilliam Jr. and formally related by court order in April 2025. In October 2025 the court issued a consolidated ruling on motions to strike across the related cases. As of June 2026 the litigation is still active, with the cases referred to a magistrate judge for discovery and regular status conferences ongoing.9CourtListener. Saliba v.

The $10 Million County and Air District Judgment
On February 18, 2026, Judge Benjamin T. Reyes II signed a final judgment in a joint civil prosecution brought by the Contra Costa County District Attorney’s Office and the Bay Area Air Quality Management District. It resolved 163 notices of violation covering conduct from early 2020 through late 2024, including the Thanksgiving 2022 spent catalyst release, illegal flaring, fires, leaking tanks, coke dust escaping the fence line, and nuisance odors in downtown Martinez. The charges spanned California’s health and safety code, business and professions code, and fish and game code.1Bay Area Air Quality Management District. MRC Settlement10Contra Costa County. MRC $10 Million Settlement
The $10 million penalty was split as follows:
- $6.35 million to the Air District, earmarked for reinvestment in affected communities.
- $3.5 million to the District Attorney’s Office Environmental Unit for enforcement.
- $100,000 to Contra Costa Health Services.
- $50,000 to the California Department of Fish and Wildlife.11CBS News. Martinez Refining Company $10 Million Penalty
On top of the penalty, the company was ordered to pay $600,000 for supplemental environmental projects: $450,000 for air filtration systems in nearby public schools, $100,000 for environmental regulator scholarships, and $50,000 for a county fish and wildlife fund. The judgment also required operational changes. The refinery must keep emissions control equipment running during startup and shutdown of its catalytic cracking unit and install enhanced monitoring systems on other equipment.1Bay Area Air Quality Management District.

Important boundary: this judgment does not cover the February 2025 fire, which is being handled as a separate matter.1Bay Area Air Quality Management District. MRC Settlement
The $4.48 Million Clean Water Act Settlement
In October 2024 the San Francisco Bay Regional Water Quality Control Board reached a $4.48 million settlement with the refinery over unauthorized wastewater discharges. The board documented 25 effluent limit exceedances and three major unauthorized discharge events between late 2022 and mid-2023:12San Francisco Bay Regional Water Quality Control Board. Order R2-2024-1041
- October 27, 2022: Over 72,000 gallons of partially treated wastewater discharged into a marsh near the refinery due to a pipeline blockage.
- January 4, 2023: Approximately 11.2 million gallons of partially treated wastewater mixed with stormwater released into a nearby marsh during severe storms.
- June 7, 2023: Over 471,000 gallons released into a retention area connected to McNabney Marsh from a broken pipe.13Local News Matters. Martinez Refinery’s $4.4 Million Settlement
Half the penalty, $2.24 million, went to the state’s Cleanup and Abatement Account. The other half was directed to environmental projects including water quality improvements in Peyton Channel and McNabney Marsh, the Martinez Watershed Rangers student stewardship program, and scientific studies on microplastics and sediment in San Francisco Bay.12San Francisco Bay Regional Water Quality Control Board. Order R2-2024-1041 Martinez Refining Company spokesperson Brandon Matson said the company settled “without administrative or civil adjudication” and attributed some of the discharges to “an unexpectedly large series of storm events.”14Silicon Valley Voice.

The February 2025 Fire and Separate Enforcement
A fire that began on February 1, 2025, burned for several days, triggered a shelter-in-place advisory, and prompted a health advisory that was not lifted until February 4. The blaze shut the facility down for roughly two months.3Contra Costa Health. Martinez Refining Company Oversight15KQED. Massive Martinez Refinery Fire Caused by Human Error, Investigation Finds
An independent investigation by JEM Advisors, commissioned by county health officials, concluded in June 2025 that human error was the cause. Contract workers from the firm TIMEC, performing a routine “turnaround” maintenance procedure, mistakenly loosened bolts on a flange containing hot hydrocarbons instead of the intended location. The report said the root cause was that “operations monitoring and control of work was inadequate for current maintenance contractor organizational capability.” Contributing factors included insufficient contractor supervision and training and regulatory constraints that limited the refinery’s ability to directly train contractors or select the most experienced workers. Six workers were evaluated by medical personnel and released.16Contra Costa News. Report Highlights Root Cause of Martinez Refining Company Fire
On February 6, 2025, the Bay Area Air District issued three Notices of Violation, citing the refinery for creating a public nuisance, failing to operate equipment as permitted, and producing excessive smoke and soot fallout.17Bay Area Air Quality Management District. Joint Statement on Martinez Refining Company Fire The Air District and the Contra Costa District Attorney’s Office announced a joint enforcement action that remained ongoing as of early 2026. Residents have also filed additional legal claims tied to the fire, citing a lack of timely emergency alerts and community-wide evacuations during the incident.2Cutter Law. Martinez Refining Company Toxic Exposure Litigation
Where Things Stand Now
As of mid-2026, the four federal personal injury suits are in active discovery before a magistrate judge, the $10 million county and air district judgment is final and imposes new monitoring and emissions control obligations on the refinery, the $4.48 million Clean Water Act settlement is closed, and the enforcement action arising from the February 2025 fire has not yet been resolved. Contra Costa County Supervisor Federal Glover said “repeated commitments to the community and to regulators to improve the culture of safety at PBF have not resulted in improvement.”5Local News Matters.
