U.S. EPA Issues Emergency Fuel Waiver for E15 Sales

The U.S. Environmental Protection Agency (EPA) issued an emergency fuel waiver to allow gasoline containing up to 15% ethanol (E15) to be sold during the summer season. E15 is granted a waiver to exceed the Reid Vapor Pressure (RVP) requirements for gasoline that are detailed in the Clean Air Act Section 211(h)(1) by 1 pound per square inch (psi) from May 1 through May 20, 2023. The waiver only extends to areas within the contiguous United States where the 1-psi waiver currently applies to gasoline containing up to 10% ethanol (E10).
