The Trump administration made it easier for oil refineries to get waivers from the nation’s biofuel law at least four months before a 2017 court decision it often cites to justify the move to the corn lobby, and the move was motivated by a desire to save the oil industry money. The timing and motivation for the Environmental Protection Agency’s policy change, revealed through court documents and an interview with a former top agency official, have not been previously reported. This reinforces the concerns of the corn industry that the decision to expand the waiver program was made at the EPA’s discretion.“EPA repeatedly told Congress its hands were tied and blamed the courts. That appears to have been a lie. EPA also said it was following Department of Energy recommendations. We also know that’s bunk. I’m going to get to the bottom of this,” U.S. Senator Chuck Grassley, a Republican from the farm state of Iowa, said.The waivers, granted to small refineries including those run by oil majors Exxon Mobil, Chevron Corp and billionaire investor Carl Icahn, saved the oil industry hundreds of millions of dollars. The waivers angered the corn lobby which argued they hurt farmers by threatening demand for ethanol.
