Identification of Additional Qualifying Renewable Fuel Pathways III and Modification to the Renewable Fuels Program

a.k.a. RFS2 - New Fuel Pathways III (biodiesel from pennycress, and ethanol from energy sorghum)

RIN: 2060-AR50 (What's this?)

Docket No.: Not yet available (What's this?)

Current Phase: Pre-Proposal (What's this?)

The Renewable Fuel Standard (RFS) 2 program was required by the Energy Independence and Security Act of 2007 (EISA 2007), which amended the Clean Air Act (CAA). The final regulations for RFS2 were published in the Federal Register on March 26, 2010 (75 FR 14670). EPA has previously published clarifications and modifications, technical amendments, and new pathways, to the final RFS2 regulations.

This proposed regulation would provide additional clarifications, modifications, and technical amendments to RFS2 and will clarify, modify and technically amend other fuels programs in 40 CFR Part 80. This proposed action would also propose amendments to Table 1 to Section 80.1426 of the RFS2 regulations to include additional fuel pathways and assign each pathway a D-Code. It would allow producers or importers of fuel produced under these pathways to generate Renewable Identification Numbers under the program, providing that the fuel meets the other requirements for renewable fuel. This proposed action would outline EPA's lifecycle greenhouse gas evaluation, specified in Clean Air Act section 211(o), as amended by EISA for several new pathways.

NPRM: Published in FR07/2017 (projected)

This site provides summaries of priority rulemakings and priority retrospective reviews of existing regulations. We update most of the site at the beginning of each month, though some data is updated more frequently if it is time sensitive. The information on this site is not intended to and does not commit EPA to specific conclusions or actions. For example, after further analysis, EPA may decide the effects of a rule would be different or it may decide to terminate a rulemaking.
