What are the differences between the old definition of “renewable biomass” and the EPA’s newly proposed definition? The proposed changes to the definition of “renewable biomass” are significant under the EPA’s new “Set” Rule published in December 2022, finalized June 14, 2023, per a court consent decree. Under the current RFS (Renewable Fuel Standard) standalone term, “renewable biomass” is defined to include the renewable feedstocks that generally qualify to produce renewable fuels and generate RINs (Renewable Identification Numbers).
The U.S. Environmental Protection Agency (EPA) officially released the long-awaited Renewable Volume Obligation (RVO) numbers and other important updates to the Renewable Fuel Standard (RFS) in its Final Rule on June 21, 2023, establishing annual obligations for the years 2023-2025. The optional 2026 RVO previously proposed in December of 2022 was omitted. See Overview of the EPA RFS Final Rulemaking 2023-2025 RVO’s.
