The U.S. Environmental Protection Agency has not yet taken action on petitions by refiners seeking retroactive biofuel blending waivers, Senator Chuck Grassley from Iowa said on June 16. The Iowa senator called on the EPA to reject such petitions in a weekly call with reporters.
Grassley said the petitions were an attempt to skirt a 10th Circuit Court of Appeals decision earlier this year that said waivers from the nation's biofuel blending laws granted to small refineries after 2010 had to take the form of an "extension."
