State senators are considering a bill that would require all regular-octane gasoline in the state to contain ten-percent ethanol.
The bill already passed in the Assembly.
At a public hearing Wednesday, senators heard from farm interests who lauded the bill and manufacturers who said the increased emissions would hurt them.
At the hearing, the manager of a Minnesota ethanol plant said the move gives farmers another source of income. Minnesota has had a ten-percent ethanol requirement for about nine years.
But spokespeople for the Sierra Club and Wisconsin Manufacturers and Commerce say the move would make ozone problems worse. They say that'd increase pressure on them to cut back on their own omissions even though the increase wouldn't be their fault.
