The Environmental Protection Agency (EPA) announced approval of 24 registration applications from 20 companies to begin making ethanol for use in gasoline with up to 15% ethanol (E15).  Ethanol producers and retailers must demonstrate compliance with local regulations and misfueling mitigation plans before E15 can be sold.  The ethanol trade association, Growth Energy, noted, “This announcement strengthens the ethanol industry’s efforts to innovate and continue to deliver domestically produced and affordable alternatives to foreign oil.  With ethanol selling an average of a dollar a gallon cheaper than gasoline and $4 per gallon on the horizon, we’d encourage all Americans to ask their local filling station how soon they will see more-affordable E15.”  E15 is expected to reach the Midwestern marketplace this summer.
