Missouri lawmakers are considering a rule change that could expand the use of ethanol in gasoline.
A legislative committee has heard testimony on a proposed rule change that would allow fuel containing a 15 percent ethanol blend to be sold.
At issue is whether the proposal by the Department of Agriculture runs awry of existing state laws. A 2006 Missouri law required regular gasoline to contain a 10 percent mix of ethanol, which generally is made from corn.
The proposed rule change would allow, but not mandate, the higher ethanol blend.
The Joint Committee on Administrative Rules plans to reconvene Wednesday to decide whether to block the rule change
The federal Environmental Protection Agency is fine with E15, but some automakers warn it could harm engines.
