US EPA says it, in consultation with DOE, expands gasoline supply to lower prices at the pump

Today, EPA in consultation with 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. 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.
