"DES MOINES, Iowa — A federal appeals court on Friday threw out a Trump-era Environmental Protection Agency rule change that allowed for the sale of a 15% ethanol gasoline blend in the summer months.
The decision deals a significant blow to the ethanol industry and corn farmers who grow the crop from which the fuel additive is made. They had anticipated increased ethanol demand through year-round sales of the higher blend.
Most gasoline sold in the U.S. today is blended with 10% ethanol. Corn farmers and ethanol refiners have pushed for the government to allow the widespread sale of a 15% ethanol blend.
The Trump administration made the change to fulfill a campaign promise to Midwest farmers. The EPA under President Donald Trump announced the change in May 2019, ending a summer ban on the E15 blend."
