Today, U.S. Environmental Protection Agency (EPA) Administrator Lee Zeldin, in consultation with U.S. Department of Energy (DOE) and in accordance with the Clean Air Act (CAA), issued a temporary emergency fuel waiver that will increase the nation’s gasoline supply and help lower prices for American families.
Beginning on September 1, 2026, EPA’s waivers will allow the sale of E10, gasoline blended with 10 percent ethanol, at a higher Reid Vapor Pressure (RVP). This action will increase the domestic gasoline supply by hundreds of thousands of barrels per day by effectively ending the summer-blend gasoline requirement early. With the increase of domestic gasoline supply on the market, Americans can expect to see reduced gas prices. As required by the CAA, EPA and DOE evaluated the current situation and determined that granting the waiver was in the public interest.
“President Trump has prioritized ensuring American families have affordable gasoline and energy. Throughout this administration, EPA has taken decisive action like issuing RVP waivers to provide relief at the pump and fortify our gasoline supply chain,” said EPA Administrator Lee Zeldin. “Today, we continue this work with our federal partners to increase supply and lower gas prices for all Americans. Across the administration, we will continue to execute President Trump’s agenda and provide Americans with a prosperous and affordable nation.”
“Increasing the supply of gasoline means lower prices for American families,” said DOE Secretary Chris Wright. “Today’s action is another example of this Administration using every available tool to cut red tape, increase the supply of gasoline, and lower prices at the pump. Thanks to President Trump’s leadership, we are advancing commonsense policies that prioritize energy addition and put the American people first.”
EPA remains committed to securing a robust fuel supply and lowering costs for American families, farmers, and manufacturers by reducing reliance on imported fuels and strengthening U.S. energy independence through commonsense rulemaking. The agency is issuing today’s waiver notice in advance to give industry adequate time to transition its fuel distribution systems.
Today’s actions will remain in place through the end of the summer control season on September 15, 2026. The action also waives state level controls in Texas, Arizona and California that extend beyond September 15, 2026, for the maximum period allowed of 20 days. As the EPA has done all summer, we will be monitoring gasoline supplies in those states and will be prepared to extend the waiver through a subsequent action as long as necessary to ensure adequate supplies of gasoline to consumers.
Since May 1, 2026, EPA’s emergency fuel waivers have been in effect to remove fuel restrictions across the country. The agency’s action has lowered gas prices in the states that have followed EPA’s suit and waived their requirements. In stark contrast, blue-state politicians in New York and California have not adopted these standards, driving up prices for their own residents. The agency will be ready to extend the emergency fuel waivers as long as the fuel supply circumstances warrant such action.
