The US Environmental Protection Agency will allow E15 gasoline to be sold in the 2024 summer driving season, the EPA said April 19, citing the wars in the Ukraine and in the Middle East, as well as OPEC+ production cuts.

The decision to issue an emergency waiver will allow the fuel -- gasoline blended with 15% ethanol -- to continue to be available to consumers in certain parts of the US from June 1 to Sept. 15. Formally, it extends the 1-psi Reid Vapor Pressure waiver that currently applies to E10 gasoline to E15 and uses Clean Air Act authority to waive smog-related regulations around higher ethanol blends in hot weather.
