Des Moines Register: Gov. Kim Reynolds is trying again to require gas stations to offer gasoline with higher blends of ethanol, after a more wide-reaching proposal last year fell victim to fights between fuel retailers, transportation groups and renewable fuel providers. Her new legislation, House Study Bill 594, advanced through an Iowa House subcommittee meeting Tuesday after lawmakers heard a range of objections offered by transportation groups, gas stations and others, as well as praise from renewable fuel producers. Fuel retailers like gas stations would be required to offer gasoline with 15% ethanol, known as E15, beginning in 2026. That would greatly expand the availability of E15, which is currently available in a fraction of Iowa’s gas stations and truck stops.
