E85 sales in Iowa finished strong during the fourth quarter of 2013 at record 2,784,326 gallons, an increase of 67% compared to fourth quarter of 2012.

Iowa Renewable Fuels Association (IRFA) policy director Grant Menke said that the record Iowa E85 sales prove the federal Renewable Fuel Standard (RFS) is working as intended, and the EPA should not reverse course on the policy as they have proposed.

"E85 is currently being sold at more than a $1 discount to regular gasoline at the wholesale level, making for some very attractive E85 prices for consumers across the state. But for this trend of record E85 sales to continue, we need a strong and growing RFS," Menke added.

Iowa has 42 ethanol refineries capable of producing over 3.8 billion gallons annually, with three cellulosic ethanol facilities currently under construction.
