Official title: Amend the Clean Air Act to modify the definition of renewable biomass for purposes of the renewable fuel standard, and for other purposes.
Introduced July 22, 2026 by Jeff Merkley · Last progress July 22, 2026
Amends the Clean Air Act definition of "renewable biomass" to clarify which forest and paper residual materials qualify, to allow specific forms of certification or attestation to EPA, and to explicitly treat Alaska Native Corporation land as "non‑Federal land" for the provision. The changes reorganize clause formatting, narrow and clarify certain categorical language (including an exclusion for commonly recycled paper), add a savings clause so forest plans need not identify biomass as an intended end use, and permit letters from specified local USDA/DOI offices or non‑Federal landowners as evidence to the Administrator.
