The US Environmental Protection Agency (EPA) will uphold the current 28 April 2025, implementation date to provide parity for E15 and E10 in Midwestern states. This action, requested by the governors of Illinois, Iowa, Minnesota, Missouri, Nebraska, Ohio, South Dakota, and Wisconsin, provides regulatory certainty for fuel suppliers and expands consumer access to E15 year-round in these states.

At the same time, in recognition of concerns raised by some regarding fuel supply transitions, EPA intends to consider granting requests for a one-year delay for those states seeking additional time for compliance. Such a request has already been made by the State of Ohio. EPA strongly urges any state requesting a one-year delay to inform the agency in writing no later than 26 February 2025.

EPA intends to consider any additional states’ request submitted by 26 February and aims to provide refiners and fuel suppliers with the final opportunity to make necessary adjustments to ensure the long-term success of year-round E15.

A legislative solution before the summer driving season to allow for the permanent, year-round sale of E15 nationwide is an option being negotiated in Congress. In the absence of congressional action, EPA is still considering issuing emergency fuel waivers to allow the year-round sale of E15.

EPA is closely monitoring fuel market conditions and considering potential emergency fuel waivers under the Clean Air Act to prevent supply disruptions and protect consumers from price volatility.
