Corn and biofuels groups expressed disappointment in the Environmental Protection Agency’s decision to finalize a rule relating to small refinery exemptions under the Renewable Fuel Standard. The final rule uses a three-year average of the Department of Energy recommended waivers as an estimate for 2020 waivers rather than an average of actual gallons waived by the EPA, as requested by biofuel supporters. The National Farmers Union says President Donald Trump broke a promise to farmers. The Trump administration in October promised to fully account for waived volumes due to small refinery waivers. NFU’s Rob Larew says, “farmers are sick and tired of this biofuels bait and switch.” Growth Energy CEO Emily Skor says more action is needed on the proposal to restore growth under the RFS, adding “this rule leaves important work unfinished.” National Corn Growers Association President Kevin Ross says the final rule “falls short of adequately addressing the demand destruction caused by EPA’s abuse of RFS refinery waivers.”
