Skip to Highlights

Highlights

GAO reviewed the Environmental Protection Agency's (EPA) new rule entitled "Renewable Fuel Standard (RFS) Program: RFS Annual Rules." GAO found that the final rule (1) modifies EPA's 2021 and 2022 statutory volume targets pursuant to the Clean Air Act (CAA), 42 U.S.C. §§ 7401 et seq., for cellulosic biofuel, advanced biofuel, and total renewable fuel; (2) establishes the 2022 volume target for biomass-based diesel and modifies the previously established cellulosic biofuel, advanced biofuel, and total renewable fuel volume requirements for 2020; (3) establishes the 2020, 2021, and 2022 renewable fuel percentage standards for all of the above-referenced biofuel categories; and also (4) addresses a judicial remand of EPA's 2016 standard-setting rulemaking, as well as several regulatory changes to EPA's RFS program.

Enclosed is our assessment of EPA's compliance with the procedural steps required by section 801(a)(1)(B)(i) through (iv) of title 5 with respect to the rule. If you have any questions about this report or wish to contact GAO officials responsible for the evaluation work relating to the subject matter of the rule, please contact Shari Brewster, Assistant General Counsel, at (202) 512-6398.
