With the Administration’s Renewable Fuel Standard announcement, the corn-based ethanol volume will be 15 billion gallons. EPA Administrator Andrew Wheeler said that standard will be maintained even when necessary small refinery waivers are approved. “It is not retroactive,” Wheeler told RRFN. “In 2020, the number will be set somewhere above 15 billion gallons knowing that we will be providing some small refineries relief and so we net out at 15 billion gallons providing that certainty for corn farmers.” Earlier this year, the Trump Administration approved the year-round use of E15. The updated biofuels plan includes support for the infrastructure needed for higher ethanol blends. In an interview with the Red River Farm Network, Wheeler discussed ethanol and the Waters of the United States.
