LaMalfa, California GOP Delegation Call on Newsom to Halt New Gas Price Hikes

June 24, 2025

Washington, D.C.—Congressman Doug LaMalfa (R-Richvale) joined the entire California Republican congressional delegation in sending a letter to Governor Gavin Newsom urging him to immediately suspend a scheduled increase to the state’s gasoline excise tax and pause the implementation of new California Air Resources Board (CARB) regulations projected to significantly raise fuel costs for California drivers.

Starting July 1, 2025, California is set to raise its gas tax to 61.2 cents per gallon. On the same day, new CARB regulations under the Low Carbon Fuel Standard (LCFS) are set to take effect—regulations estimated by University of Pennsylvania economists to drive fuel prices up by as much as 65 cents per gallon. Combined, these changes will further strain California’s already fragile fuel supply and add more costs for families and businesses across the state.

“At a time when Californians are already paying $1.44 more per gallon than the national average, the last thing they need is another gas tax hike and a costly new mandate from unelected CARB officials,” said Rep. LaMalfa. “The Phillips 66 refinery is set to close this fall, and Valero’s Benicia facility will follow next spring. Together, those shutdowns will cut California’s refining capacity by over 20 percent. Resulting in less fuel available on the market, higher prices, and more pain for everyone. Instead of addressing this looming supply crisis, the Governor is adding 1.6 cents to the gas tax and letting CARB push through a regulation that is estimated to raise prices by up to 65 cents per gallon. These policies are not just tone-deaf, they’re dangerous to California’s economy. The Governor continues to ignore this reality. Refusing to change course will only make things worse.”

These price increases come as California faces a looming supply crisis due to the scheduled closures of two major in-state refineries. According to a May 2025 report from the University of Southern California’s Marshall School of Business, the combined shutdown of the Phillips 66 refinery in Los Angeles and the Valero refinery in Benicia could result in a 21% drop in California’s refining capacity. This shortfall is expected to create a gasoline supply deficit of up to 13.1 million gallons per day and push prices as high as $8.43 per gallon by the end of 2026, especially when combined with the effects of new state mandates like the LCFS, Cap-and-Trade expansion, and excise tax increases.

The USC study also warns that these disruptions will ripple across the economy, impacting air travel, food delivery, agriculture, manufacturing, and healthcare, while placing further pressure on household budgets and reducing state tax revenues at a time when California faces a projected $73 billion budget deficit.

The California Republican congressional delegation has consistently urged the Governor to suspend the gas tax, address in-state supply constraints, and reject policies that deepen the cost-of-living crisis, but to date continue to be ignored.
