Oregon House Bill 2373 has sponsorship from nine state representatives and one state senator. Specifically, the proposal amends the energy policy in two ways. First, the legislation would repeal the rule to "sell only gasoline blended with specified percentage of ethanol." It would also eliminate the requirement for the State Department of Agriculture "to monitor ethanol fuel production and issue notice when ethanol production reaches specified level." You can read the full text of the bill in PDF format, here.
The Specialty Equipment Market Association (SEMA) appears to be lending its support to the bill. The lobbying group says the proposal "recognizes that while the current ethanol mandate does not apply to fuel used in antique, all-terrain and racing vehicles, there has been an inability to obtain unblended gasoline for engines that may be damaged by ethanol." Of course, if that's the kind of fuel you're looking for, you can use the website Buy Real Gas to do just that.
If successful, Oregon wouldn't be the first state to get rid of its ethanol mandate. Florida passed a repeal of E10 in 2013.
