Approved Pathways for Renewable Fuel

Below is a list of approved fuel pathways under the RFS program. For a full description of the requirements for these pathways, see the RFS Regulations at 40 CFR part 80 subpart M.

• Generally Applicable Pathways
• Completed Pathway Assessments (Non-EP3)
• Efficient Producer Petition Process (EP3) Determinations

Generally Applicable Pathways

Table 2 to § 80.1426—Advanced Technologies

Corn oil fractionation that is applied to at least 90% of the corn used to produce ethanol on a calendar year basis.

Corn oil extraction that is applied to the whole stillage and/or derivatives of whole stillage and results in recovery of corn oil at an annual average rate equal to or greater than 1.33 pounds oil per bushel of corn processed into ethanol.

Membrane separation in which at least 90% of ethanol dehydration is carried out using a hydrophilic membrane on a calendar year basis.

Raw starch hydrolysis that is used for at least 90% of starch hydrolysis used to produce ethanol instead of hydrolysis using a traditional high heat cooking process, calculated on a calendar year basis.

Combined heat and power such that, on a calendar year basis, at least 90% of the thermal energy associated with ethanol production (including thermal energy produced at the facility and that which is derived from an off-site waste heat supplier), exclusive of any thermal energy used for the drying of distillers grains and solubles, is used to produce electricity prior to being used to meet the process heat requirements of the facility.
