Some ethanol interests are understandably concerned about President-elect Trump's selection of Oklahoma AG Scott Pruitt as head of the EPA, considering his previous opposition to the Renewable Fuel Standard.

But Iowa Gov. Terry Branstad, Trump's ambassador to China, got his assurances about Pruitt from the president-elect himself. Branstad says he talked to Trump during his "Thank You" tour in Des Moines last week and was told, “Don’t worry, he’s going to be for ethanol.”

The EPA, meantime, was acting within the law when it considered Argentine biodiesel imports as part of RFS requirements.

The National Biodiesel Board filed a petition in 2015, taking issue with the EPA's decision to change rulemaking about foreign biodiesel and the RFS.

A District of Columbia Court of Appeals ruled the EPA's action was “neither arbitrary nor capricious, as it comports with agency regulations.”
