The U.S. Environmental Protection Agency (EPA) today announced that it expects to make a final determination in mid-2010 regarding whether to increase the allowable ethanol content in fuel.

The agency responded in a letter sent today to Growth Energy, the association that requested a waiver that would allow for the use of up to 15 percent of ethanol in gasoline. EPA says that while not all tests have been completed, the results of two tests indicate that engines in newer cars likely can handle an ethanol blend higher than the current 10-percent limit. The agency will decide whether to raise the blending limit when more testing data is available. EPA also announced that it has begun the process to craft the labeling requirements that will be necessary if the blending limit is raised.
