Renewable Fuel Standard Program (RFS2): 

Final Rule 

(signed February 3, 2010) 

EPA is finalizing changes to the Renewable Fuel Standard 

program, as required by the Energy Independence and Security 

Act of 2007, to ensure that transportation fuel sold in the 

United State contains a minimum volume of renewable fuel. 

The new renewable fuel standards increase the volume of 

renewable fuel required to be blended into transportation fuel 

to 36 billion gallons by 2022. The rule was developed in 

collaboration with refiners, renewable fuel producers, and many 

other stakeholders.

final rule for RFS2 is published in the Federal Register, not all material in the docket is 

available to the public. Several inquires have been received requesting early access to some 

of this supporting documentation regarding the lifecycle GHG calculations. In an effort to 

make additional material available as soon as possible to interested parties, EPA is providing 

via this zip file access to a subset of the docket material pertaining to the lifecycle analysis.
