This action proposes various changes to our fuel and renewable fuel regulations to remove barriers to the production and use of renewable fuels. First, this action would resolve several outstanding issues and provide clarification on certain Renewal Food Standard (RFS) requirements. Second, this action would propose to allow for a feedstock partially converted at one facility (referred to as a biointermediate) to be fully converted into finished renewable fuel at another facility. Finally, this action would provide production flexibilities and carry over gasoline fuel quality standards to gasoline-ethanol blends containing 16 to 83 volume percent ethanol (referred to as ethanol flex fuel (EFF). The increased flexibility provided by this rule for biointermediates and EFF could result in the increased production and use of renewable fuels in support of the RFS program.
