Key points:
- California loses 35% of crude refining capacity through state policies and regulatory actions.
- Refinery closures have slashed gasoline production by 40% and jet fuel by 30%.
- State now imports more jet fuel in two months than past 36 years combined.
- Military fuel reserves drained to prevent rationing and systemic collapse.
- Ports of Los Angeles, Long Beach, and Oakland cannot handle massive fuel import volumes.
- If two more refineries close, complete logistical collapse becomes inevitable.
- Environmental lawsuit threatens to trigger immediate catastrophic fuel deficits.
Policy-driven destruction: How state regulations dismantled an industry
The timeline of California’s refining collapse reads as a case study in regulatory overreach. Assembly Bill X2-1, signed in October 2024, mandated minimum fuel storage levels that drove operating costs to unsustainable heights. The Phillips 66 Wilmington refinery shut down on October 17, 2025, removing 139,000 barrels per day from the state’s supply. Valero followed on January 31, 2026, taking a staggering $1.1 billion loss to close its Benicia refinery after being burdened by an $82 million fine and the new tank storage mandate. Marathon Martinez and Phillips 66 Rodeo converted operations to renewable diesel in 2023, removing another 260,000 barrels per day of crude processing capacity.
The refineries that remain are sending desperate warnings. Andy Walz, Chevron Midstream and Downstream President, stated on March 6, 2026: “I am extremely worried! I do believe we should declare a state of emergency in the state of California. If you close a refinery, it doesn’t come back… if we close, we do not come back.” PBF Energy warned on February 25, 2026, that unless the California Air Resources Board places in-state refineries on equal footing with importers, the company “will be forced to address the viability of our in-state operations, along with every other refiner in the state.”
California demands 58 million gallons of transportation fuel daily, including 37 million gallons of gasoline for 36 million vehicles, 11 million gallons of jet fuel for military and international airports, and 10 million gallons of diesel for trucking and construction. The state has no pipelines over the Sierra Nevada mountains. All fuel must either be refined within California or shipped across the Pacific Ocean from Gulf Coast refineries or foreign countries with gross polluting facilities.
The lawsuit that could trigger the cliff edge
The environmental activist group Communities for a Better Environment is now suing the Air Board to force withdrawal of a fragile compromise on Cap-and-Invest amendments. If this lawsuit succeeds, PBF Energy, the smallest of seven remaining operating refineries, will likely shutter its operations. The consequences would be immediate and catastrophic.
A PBF shutdown would eliminate 23% of California’s gasoline supply, hitting the Bay Area with 30% losses and Southern California with 20% losses. Jet fuel supplies would drop by 40% to 50%, affecting 50% of Sacramento and Oakland airports, 40% of San Francisco International and San Jose, and 30% of Los Angeles International. Diesel losses of 2.7 to 3 million gallons per day would cripple commercial trucking and agriculture. Marine fuel supplies would drop by over 50%, threatening operations at the Port of Los Angeles and Port of Long Beach.
The ports are not designed to import the humongous volumes of transportation fuel that California requires. Shipments arriving from the Gulf and East Coasts must navigate the Panama Canal and offload at refinery docks into storage tanks, simulating operations as if the refineries remained online. Actual port operations face an existential threat here.
National security implications demand federal action
California’s crisis cannot be dismissed as a state-level problem. The West Coast’s ports serve as critical infrastructure for the entire Pacific theater of U.S. military operations. Military fuel storage reserves have already been drained substantially to prevent systemic collapse and fuel rationing. Gulf Coast refineries run at 98% capacity, yet California still required emergency draws from national reserves.
If all seven remaining refineries close, the complete collapse of West Coast ports, airports, and military installations becomes unavoidable. The food supply chain extending from California’s Central Valley into the American heartland would be permanently compromised. This is not a hypothetical scenario but a real threat unfolding with each regulatory action and environmental lawsuit.
The federal government must invoke the Defense Production Act to protect and preserve California’s remaining refining infrastructure, just as it did to bring Sable offshore oil platforms back online. The surviving refiners have made their position clear. Marathon Petroleum stated on March 9, 2026: “CARB’s proposal would further widen the cost disparity, forcing refineries to reconsider whether refinery operations in California remain viable… The net effect will be an increase in global greenhouse gas emissions by relying on foreign imports with lower environmental standards.”
California’s demise would become a national security risk for America if not stabilized. The state does not need a federal bailout. It needs the rectification of adversarial policies including ABX2-1, Cap and Trade, SBX1-2, and the aggressive litigation from activist groups that have systematically dismantled domestic refining capacity. The fourth-largest economy in the world cannot be allowed to collapse under the weight of its own regulatory apparatus.
