U.S. ethanol producer Archer Daniels Midland Co on Monday asked the Environmental Protection Agency to allow U.S. fuel blends with up to 12 percent ethanol while the EPA continues its review an earlier request to raise the U.S. ethanol blend rate to 15 percent.
Worries that higher blends could damage engines of older vehicles are among the top concerns delaying an EPA ruling on a March 2009 request by ethanol supporters to raise the blend rate as high as 15 percent, up from 10 percent currently.
ADM said that the EPA could allow the marketing of fuel blends with up to 12 percent ethanol, known as E12, to all vehicles because it is "substantially similar" to the current E10 fuel blends.
