What the ethanol bill on the governor's desk would mean at the pump

River to River, hosted by Ben Kieffer

A new law would increase access to E15 fuel at the pump in Iowa.

The Iowa Legislature sent a bill to the governor’s desk Tuesday with bipartisan support that would require many Iowa gas stations to sell fuel with higher blends of ethanol. This state-level mandate would force retailers to offer E15 fuel at the pump. E15 is a blend of gasoline that is 15 percent ethanol.

On this episode of River to River, host Ben Kieffer hears from the ethanol industry and its critics about what this increase in access to E15 fuel will mean.

We also hear from Dan Diekema of the University of Iowa Hospitals and Clinics about the state of the COVID-19 pandemic.
