EPA Denial of Petition for Partial Waiver of the 2023 Cellulosic Biofuel Requirement

On March 15, 2024, EPA denied a petition from the American Petrochemical & Fuel Manufacturers for a partial waiver of the 2023 cellulosic biofuel standard under the Renewable Fuel Standard. AFPM requested that EPA waive a portion of the cellulosic biofuel standard under Clean Air Act section 211(o)(7) on December 22, 2023. EPA evaluated the AFPM petition and determined that sufficient cellulosic RINs and compliance flexibilities exist for obligated parties to comply with the existing 2023 cellulosic biofuel standard. Furthermore, EPA determined that a partial waiver of the cellulosic biofuel standard would be injurious to the RFS program because it would be disruptive to program participants and could result in reduced demand for cellulosic biofuel production.
