California drivers may soon see some relief at the pump as the Trump administration takes steps to increase the gasoline supply.
The Environmental Protection Agency announced Thursday the issuance of an emergency fuel waiver. This measure aims to boost the domestic gasoline supply by hundreds of thousands of barrels daily, potentially reducing fuel costs for drivers in the Golden State.
Starting September 1, the EPA will permit the sale of E10 gasoline—comprising 10% ethanol—at a higher volatility level than is usually allowed during the summer months. This adjustment enables an earlier transition away from the more stringent summer gasoline blend by approximately two weeks.
The waiver will remain active until September 15, marking the end of the summer control season, with a particular focus on California.
The EPA is also temporarily lifting some state-level gasoline controls in California that extend past September 15. These waivers may last up to 20 days, with a possibility of further extension, according to the agency.
“Increasing the supply of gasoline means lower prices for American families,” stated Energy Secretary Chris Wright.
EPA Administrator Lee Zeldin echoed this sentiment, explaining that the administration is using the waivers to “increase supply and lower gas prices for all Americans.”
This initiative comes as California drivers continue to face high fuel prices.
The state is particularly susceptible to fuel price spikes due to its isolated fuel market, refinery closures, and reliance on imports. As of Thursday, the average gasoline price in California was about $5.59 per gallon, according to AAA.
The EPA’s announcement also criticized California’s fuel policies, suggesting that state officials have resisted federal standards that could increase supply.
The agency noted that emergency waivers have been in place since May 1, claiming that states adopting these changes have experienced lower gas prices, while pointing out that California and New York have not complied.
California has become increasingly dependent on imported gasoline following refinery closures.
