Growth Energy and Casey’s General Stores Inc. announced that Casey’s will expand its E15 offering to more than 60 new sites this summer across their footprint following the Environmental Protection Agency’s (EPA) approval of E15 year-round.

In their statements, Casey’s and Growth Energy attributed this rapid expansion to the lifting of an outdated regulation that now allows American drivers to access E15 year-round. 

“The summertime E15 restrictions have been a major concern for us for a long time and would typically slow down our E15 expansion,” said Casey’s Director of Fuels Nathaniel Doddridge. “Now that we know we can provide our guests with a consistent experience at the fuel pump year-round, we are expanding E15 at a faster pace to stay ahead of our competition.”

Growth Energy represents producers and supporters of ethanol working to bring consumers better choices at the fuel pump, grow America’s economy and improve the environment for future generations. The company’s national campaign serves as the leading source of information for consumers seeking cleaner, more affordable fueling options. 

“Growth Energy has relentlessly led the fight on year-round E15 to grow the ethanol marketplace and give all drivers access to a cleaner, engine smart fuel,” said Growth Energy CEO Emily Skor. “We are thrilled that Casey’s will be rolling out E15 at dozens of new sites this summer, and know from conversations with retailers all over the country that they will soon be joined by others who’ve been waiting for this day.”

E15 is currently sold at 1,807 stations in 31 states.
