Renewable Fuel Standard Program

Renewable Fuel Pathways II Final Rule to Identify Additional Fuel Pathways under Renewable Fuel Standard Program

Rule Summary

You may need a PDF reader to view some of the files on this page. See EPA’s About PDF page to learn more.

EPA has qualified additional renewable fuel production pathways and pathway components that could be used in producing qualifying renewable fuel under the RFS program. This final rule describes EPA’s evaluation of biofuels derived from biogas fuel pathways under the RFS program. These pathways have the potential to provide notable volumes of cellulosic biofuel for use in complying with the RFS program, since significant volumes of advanced biofuels are already being generated for fuel made from biogas, and in many cases this same fuel will qualify for cellulosic RINs when this rule becomes effective.

This action qualifies the following as cellulosic and advanced fuel pathways under the Renewable Fuels Standards (RFS):

  • Compressed natural gas produced from biogas from landfills, municipal wastewater treatment facility digesters, agricultural digesters, and separated MSW digesters
  • Liquefied natural gas produced from biogas from landfills, municipal wastewater treatment facility digesters, agricultural digesters, and separated MSW digesters
  • Electricity used to power electric vehicles produced from biogas from landfills, municipal
    wastewater treatment facility digesters, agricultural digesters, and separated MSW digesters

EPA is also finalizing other minor amendments related to survey requirements associated with the ultra-low sulfur diesel (ULSD) program and misfueling mitigation regulations for 15 volume percent ethanol blends (E15).
