The U.S. Environmental Protection Agency has rescinded three waivers that had excused Sinclair Oil refineries in Wyoming from the federal requirement to blend ethanol into gasoline. Iowa Renewable Fuels Association executive director Monte Shaw says the Biden Administration’s E-P-A administrator will be in Iowa today and will tour an ethanol plant.

Other unresolved items include setting the federal ethanol production mandate for this year and announcing E-P-A labeling and equipment rules so retailers can sell E-15 — gas with 15 percent ethanol — year-round.
