The state Senate has spiked the ethanol bill.
The Senate voted 17-15 to indefinitely put off action on the measure that would have required gasoline sold in Wisconsin to contain ethanol.
The bill will not likely see any action before the end of the legislative session next month, although supporters could push to revive it.
It would have required all regular unleaded gasoline to contain 10% ethanol by October 2007. It was approved in the Assembly and had the support of the governor.
Critics say government shouldn't force consumers to use a product they say will harm small engines, be less fuel efficient than regular gas and create more smog.
Ethanol is produced at several sites in the state including Stanley in Chippewa County and soon at a plant under construction in Dunn County.
