The White House on Wednesday requested Congress approve year-round sales of E15 gasoline, inserting the measure into a supplemental funding bill as an urgent policy priority.
The request would make the sale of gasoline blended with 15 percent ethanol permanent nationwide. Presently, gasoline with 10 percent ethanol can be sold year-round, but E15 faces seasonal restrictions in the summer months because it evaporates quickly in the heat and can contribute to smog formation.
