Hearing More About the Dysfunctional RFS (Renewable Fuel Standard)


With another congressional hearing on the Renewable Fuel Standard (RFS) scheduled this week, a couple of glimpses behind the curtain at EPA help explain why the RFS is dysfunctional and needs to be repealed or dramatically overhauled.

Glimpse No. 1 comes from a U.S. Senate subcommittee hearing last month, chaired by Sen. James Lankford of Oklahoma. The witness was EPA’s Janet McCabe, acting assistant administrator for the office of air and radiation. Tune in at about the 1-hour, 24-minute mark of the archived video to see Lankford’s discussion with McCabe about how EPA sets annual ethanol use requirements under the RFS.

The overriding issue is the ethanol “blend wall” – the point where the RFS requires blending more ethanol into the national fuel supply than can be used in E10 gasoline. At that point some think that higher ethanol-blend fuels like E15 and E85 will help meet RFS ethanol mandates. But E15 can cause damage to engines and fuel systems in vehicles that weren’t designed to use it – as well as outdoor power equipment, boats and motorcycles. And E85 is less energy-dense than standard gasoline – getting fewer miles to the gallon. It represents a tiny fraction of overall gasoline demand, a strong signal from consumers.
