Amends the Clean Air Act definition of "renewable biomass" to clarify which forest and paper residuals qualify, to add specific certification/attestation procedures for non‑Federal land, and to expressly include Alaska Native Corporation land in the definition of non‑Federal land for these purposes. It also adds a savings clause stating certain forest or resource management plans need not expressly identify renewable fuel or biomass energy as an intended end use to be eligible when the project is otherwise authorized and consistent with the plan. The changes narrow and reword some categorical language (including an explicit exclusion for paper commonly recycled), add procedural paths for documentation to the EPA Administrator (letters from non‑Federal landowners and local USDA/DOI offices), and make a technical reformatting of clause numbering in the statute to improve clarity.
