Now that the Environmental Protection Agency has finally allowed eight states the ability to sell E15 year-round by April 28, two of those states have decided they’re not ready yet.

On Friday, EPA announced it would act on “requests from South Dakota and Ohio seeking a one-year extension of the current implementation date to remove the 1-psi volatility waiver for E10.”

This action follows the February 26, 2025 deadline for states to submit written requests for delay. Kansas, which was not among the eight states addressed in the final rule, submitted a similar request. The agency intends to act expeditiously to delay implementation for South Dakota and Ohio until the spring of 2026. This will be the last year an extension can be provided to any of the eight states addressed in the final rule.

EPA notes that 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.
