Biden restores summer sales of E15, a farm-state goal

The EPA will issue an emergency waiver allowing sales of E15 — gasoline that is 15 percent corn ethanol — this summer, announced President Biden on Tuesday, ahead of a trip to Iowa, the No. 1 corn- and ethanol-producing state. The step will save motorists up to 10 cents a gallon on surging gasoline prices and aid the rural economy, said the White House.
