(NAFB.com) – Senator Chuck Grassley led an Iowa delegation of lawmakers in a letter urging the Environmental Protection Agency to allow for summertime E15 sales in 2024. Last week, the EPA finalized a rule to approve year-round E15 sales, but delayed implementation until 2025. The rule allows states to use the same volatility limits for E15 and E10 and was in response to a petition by governors of eight midwestern states seeking the year-round availability of E15. The petition includes Minnesota, Missouri, Nebraska, Ohio, South Dakota and Wisconsin. Grassley and the Iowa delegation contend the delay “will have devastating effects on biofuels producers, farmers, and families across the country.” The letter states, “We request, once again, that the EPA immediately implement its rule to ensure E15 is available year-round no later than March 31, 2024.” Representatives Zack Nunn, Randy Feenstra, Ashley Hinton, and Marionette Miller-Meeks signed the letter, along with Senators Grassley and Joni Ernst.
