The EPA is also partially waiving the 2025 cellulosic biofuel volume requirement and revising the associated percentage standard due to a shortfall in cellulosic biofuel production. Finally, the EPA is promulgating several regulatory changes to the RFS program, including removing renewable electricity as a qualifying renewable fuel under the RFS program (eRINs) and making minor revisions to the biogas provisions of the RFS program.
