Registering E15 fuel

Fuel producers must meet the following EPA requirements for E15 fuel.

  1. Misfueling mitigation plans
  2. Compliance survey plans
  3. Fuel product registration under 40 CFR Part 79

Misfueling Mitigation Plans

The Misfueling Mitigation Rule requires companies to submit a Misfueling Mitigation Plan to EPA for approval prior to selling E15. These plans must include measures that the fuel producer will take to reduce the potential of misfueling vehicles that cannot use E15.

Companies can submit their own MMPs or request EPA approval to use the Model Misfueling Mitigation Plan. Companies cannot introduce E15 into commerce until EPA has approved the request and the plan has been implemented.

Follow these three (3) steps to submit the request:

  1. Compose a letter on company letterhead that includes the following:
    1. A request to use the Model Misfueling Mitigation Plan
    2. The company’s planned E15-related business (e.g., refiner, ethanol producer, oxygenate blender, retailer).
  2. Have a company official sign the letter
  3. Mail the letter to the appropriate address: EPA's Fuel Programs Mailing Addresses

After receiving the letter, EPA may seek additional information and/or require additional misfueling mitigation measures, as appropriate, considering the company’s specific circumstances.

Compliance Survey Plans

Companies that use the Model Misfueling Mitigation Plan must submit a survey plan for EPA approval and cannot introduce E15 into commerce until EPA has approved the survey plan and the plan has been implemented.

Companies may choose to submit their own survey plans or use an approved survey plan.

The RFG Survey Association has submitted survey plans for every year that the E15 waiver has been in place. Companies that enroll in the RFGSA survey plan meet the waiver condition for a survey plan. Companies that wish to enroll in the RFGSA’s E15 Compliance Survey program should contact RFGSA.

Companies may submit their own survey plans by mailing a paper copy to the appropriate address: EPA's Fuels Programs Mailing Addresses

Fuel product registration under 40 CFR Part 79

All individual fuel and fuel additive manufacturers involved in manufacturing E15 must register with EPA. Manufacturers are required to:

  • Analyze the combustion and evaporative emissions generated by their fuel and fuel additive products
  • Survey existing scientific information for each product
  • Conduct tests to screen for potential adverse health effects of these emissions, where adequate information is not available.
