Rule Summary

In response to a request from the Governors of Ohio and South Dakota, the Environmental Protection Agency is renewing the extension of the effective date of the removal of the 1-psi volatility waiver for gasoline-ethanol blends containing 10 percent ethanol in Ohio and nine counties in South Dakota. EPA finds that there would be an insufficient supply of gasoline in Ohio and nine counties in South Dakota if the removal of the 1-psi waiver were to go into effect as currently required on April 28, 2025. Therefore, we are renewing the extension of the effective date by one year to April 28, 2026, for the entire state of Ohio, and the following nine counties in South Dakota: Butte, Custer, Fall River, Harding, Lawrence, Meade, Oglala Lakota, Pennington, and Perkins.
