The U.S. Environmental Protection Agency on April 28 issued an emergency fuel waiver allowing the sale of E15 gasoline nationwide during the summer driving season. E15 is gasoline blended with 15% ethanol and is typically banned for summer sale because of the risk of its emissions causing smog formation. This is the fourth consecutive year the waiver has been granted. The move also is designed to offer more gas options to consumers, and potentially lower gas prices while reducing reliance on imported fuels. The Clean Air Act allows the EPA administrator, in consultation with the U.S. Department of Energy, to temporarily waive certain fuel requirements to address shortages. The EPA has also waived provisions that would have otherwise made E10 gasoline sold in those states meet a more stringent standard than conventional gasoline in other parts of the country. EPA’s action for these states means E15 and E10 are sold across the region on equal footing, helping ensure adequate gasoline supplies to consumers across the country, the agency stated in a press release.
