(NAFB.com) – Clean Fuels Alliance America filed written comments on the Environmental Protection Agency’s proposed Partial Waiver of 2024 Cellulosic Biofuel Volumes. Clean Fuels is asking the agency to pause the rulemaking process until the agency can provide a full accounting of available cellulosic RINs for 2024 and consider whether pending small refinery exemptions or other mechanisms provide relief to refiners. Also, the group encourages the EPA to address the significant underestimation of biomass-based diesel and advanced biofuel volumes for 2024 and 2025. “We cannot accurately evaluate EPA’s calculation of an inadequate supply of cellulosic RINs for 2024 without first knowing the number of RINs that might be returned to the market through small refinery exemptions,” Clean Fuels wrote. “We ask that EPA finalize a step-change in 2024 advanced RVOs to EPA’s own projected advanced RIN generation, which is currently expected to exceed the required volumes by at least 2.6 billion RINs.”
