The Environmental Protection Agency (EPA) announced Thursday that it is taking emergency action to expand the nation’s gasoline supply and help bring down prices for Americans.
Beginning September 1, the EPA will allow E10 gasoline to be sold at a higher Reid Vapor Pressure. The temporary waiver effectively ends the costly summer-blend requirement early, freeing up hundreds of thousands of additional barrels of gasoline per day for American drivers.

“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,” EPA Administrator Lee Zeldin said. “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.”
The waiver will remain in effect through September 15, when the federal summer-blend requirements ordinarily expire. It will also temporarily override stricter state-level fuel rules in California, Texas, and Arizona, states where summer-blend restrictions extend beyond the federal deadline, for up to 20 additional days.

“Increasing the supply of gasoline means lower prices for American families,” DOE Secretary Chris Wright said. “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.”
