Defense Production Act Invoked to Reopen California Pipeline as Iran War Squeezes West Coast Refiners

Energy Secretary Chris Wright invoked Cold War-era emergency powers Friday to force the restart of an idle California offshore oil pipeline, citing Iran conflict disruptions—a move California Governor Gavin Newsom immediately vowed to challenge in court. The Defense Production Act order directs Houston-based Sable Offshore to restore operations at the Santa Ynez Unit, shut since a 2015 spill released 142,000 gallons of crude along the Santa Barbara coast.

The facility can produce about 50,000 barrels of oil per day and would replace nearly 1.5 million barrels of foreign crude each month, according to Department of Energy estimates—a roughly 15% increase in California’s in-state production. The order escalates a fight over whether federal authority can override California regulators blocking Sable Offshore’s plan to restart the pipeline, testing the outer limits of executive power amid the most severe oil price spike since 2022.

Strait of Hormuz Closure Drives West Coast Crisis

On February 28, the US and Israel launched strikes against Iran targeting key officials and military facilities. The Iranian Revolutionary Guard Corps moved to block the Strait of Hormuz, virtually halting passage of one-fifth of global oil and LNG trade.

California refiners face unique vulnerability. Over the past month, average regular gasoline prices in California jumped more than 18%, hitting $5.42 per gallon Friday—much higher than the national average of $3.63, per AAA data. Jet fuel prices in Los Angeles soared more than 47% to about $3.85 a gallon since the conflict started.

A shortage of Middle Eastern crude has forced refineries in China, Korea and India to cut back production, with some declaring force majeure, according to Reuters. “All the crude that West Coast refiners import from the Middle East is at risk,” said Matt Smith, an analyst at Kpler. Availability of alternative crude is limited due to strong demand from Asia, with just about half a million barrels of Canadian oil available to West Coast refiners due to Trans Mountain Pipeline constraints and demand from Chinese buyers.

Federal Override of State Authority

A March 3 Justice Department legal opinion concluded a Defense Production Act order could preempt state law and override a 2020 federal consent decree requiring California State Fire Marshal approval before restart. The Defense Production Act, passed in 1950, gives the president sweeping powers to allocate and redirect energy, labor, materials and other economic resources in response to shortages of import to national security.

The invocation marks unprecedented use of wartime authority. The law has never before been used to compel an oil company to resume production from idled infrastructure and override pending state requirements, according to the Center for Biological Diversity.

California officials say the move defies court orders and state oversight, with Governor Newsom pledging to sue. In 2015, 142,000 gallons of crude oil spilled onshore near Refugio State Beach, causing 21,000 gallons to flow into the Pacific Ocean—thousands of birds and marine mammals were killed, and 138 square miles of fisheries were closed for weeks, triggering a $23.3 million settlement.

California’s Natural Resources Agency ordered Sable to remove a pipeline crossing Gaviota State Park days after the federal government instructed the company to begin pumping crude through the conduit, according to Bloomberg.

Refining Capacity Loss Amplifies Pressure

The West Coast faces compounding supply constraints. The Los Angeles and Benicia refineries account for 17% of California refinery capacity and 11% of West Coast capacity. The relative lack of logistical connectivity on the West Coast to other refinery hubs means the supply shortfall cannot be easily filled by other refineries elsewhere in the country.

The most likely source of replacement fuels will be imports from Asia—California’s unique CARBOB gasoline can only be manufactured by properly equipped refineries, with Phillips 66 planning to produce some at its Washington refinery and refineries in India and South Korea meeting specifications, per EIA analysis.

Energy economist Philip Verleger wrote California drivers can expect gasoline and diesel shortages soon and prices possibly above unprecedented levels of $10 per gallon. West Coast states will need to reduce gasoline and diesel use by 20% if nations that export fuel to the region restrict flows to protect domestic markets.

Geopolitical Drivers and Energy Security Claims

The administration frames the order as national security imperative. DOE noted more than 60 percent of oil refined in California is imported, with significant share moving through the Strait of Hormuz—Sable’s facilities could displace up to 1.5 million barrels of foreign crude monthly.

President Trump’s “energy dominance” strategy has translated into fossil fuel-friendly policy aimed at strengthening US leverage in global markets through deregulation and rollback of renewable subsidies, according to Earth.org analysis. A recent report from California Assemblyman Stan Ellis argued the state’s energy policies could contribute to supply chain disruptions for military fuels and compromise US force readiness, citing closures of major refineries threatening pipelines that provide supplies to California’s surviving refineries, civilian markets, and military installations in California, Arizona and Nevada.

Critics dispute the security rationale. Newsom’s office argued restarting the Sable pipeline would have little effect on global oil prices, citing estimates its output would represent roughly 0.05% of total oil production. “This move will not address the volatile market being made more chaotic by the actions of this administration in Iran,” said Senate President pro Tempore Monique Limón.

Legal Showdown and Precedent Implications

A Santa Barbara judge tentatively ruled the Trump administration’s intervention wasn’t enough to let Sable restart the pipeline—Geck’s tentative ruling is the first sign federal efforts to override state authority may face resistance in court, according to CalMatters.

Sable has been cited by the California Coastal Commission for unlawful work in sensitive coastal habitat and sued by the California attorney general and Santa Barbara district attorney for violations tied to unlawful discharges. Sable announced it restarted oil production at Platform Harmony Saturday, March 14 at Energy Secretary Wright’s direction, with production ramp-up anticipated at Platforms Harmony and Heritage this month and Platform Hondo in June at an expected gross oil rate of 50,000 barrels per day.

What to Watch

California’s legal challenge will test whether Defense Production Act authority can preempt state environmental and safety oversight—a precedent with implications far beyond energy policy. Allowing the federal government to override state law so an oil company can restart pipelines would set a dangerous precedent, environmental groups argue.

Oil market direction hinges on Strait of Hormuz reopening timeline. EIA forecasts Brent will remain above $95/barrel over the next two months before falling below $80 in Q3 2026 and around $70 by year-end, averaging $64 in 2027—highly dependent on modeled assumptions of conflict duration and resulting production outages.

Watch whether Trump temporarily waives the Jones Act, which requires domestic crude to be shipped on US-flagged tankers, making it more expensive for California refiners to ship from the Gulf Coast. California coastal communities face renewed spill risk if Sable begins flowing crude through corroded infrastructure before completing repairs mandated by state regulators—a collision between Energy Security claims and environmental protection that will define federalism boundaries in the climate transition era.
