Outboard Expert: EPA Delays Decision on E15 Ethanol Fuel

The December 1st deadline for action on the wavier to allow E15 came and went.

The U.S. Environmental Protection Agency (EPA) today delayed making a final decision on a waiver request that would permit the use of up to 15 percent ethanol in gasoline motor fuel. That waiver request had been made in March 2009 by Growth Energy, a bio-fuels trade association representing 51 ethanol producers. The waiver request was opposed by the marine industry and dozens of other trade and environmental organizations, from the Alliance of Automobile Manufacturers to the Sierra Club. Boats.com has reported on ethanol issues related to marine engines before (see The Outboard Expert: Ethanol Alert and Will Politics Trump Science in the Ethanol Debate?).

Ethanol content in gasoline could be increased to 15 percent and potentially damage marine engines.

Ethanol content in gasoline could be increased to 15 percent and potentially damage marine engines.

In a letter to Growth Energy, the EPA said 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, perhaps by mid-2010.
A media release issued by the EPA today makes no mention of testing so-called E15 fuel in older cars and trucks, or in off-road vehicles, including boats. According to the National Marine Manufacturers Association (NMMA), none of the 18 million boats currently in operation in the U.S. have been designed, certified or warranted to run on anything above E10 fuel, which contains up to 10 percent ethanol. The EPA release implies that it may approve E15 for 2001 and newer vehicles by mid-2010 unless data reveal problems. The NMMA is adamant that no decision should be made on E15 until all independent scientific studies confirm that it is compatible with both on-road and non-road engines.
“The EPA appears to only be looking at automotive testing,” said Mat Dunn, NMMA Legislative Director. “We think that is inappropriate and in violation of the Clean Air Act. The EPA should also be conducting tests on off-road engines, including marine engines, and we will insist on that testing. Any attempt to bifurcate the fuel supply by allowing E15 for only certain automobiles would lead to a myriad of misfueling, liability and consumer safety issues and likely cause the price of fuel for boaters to increase while availability of compatible blends decreases.”
It would appear, at least, that boat owners have dodged the ethanol bullet for the 2010 boating season. In the meantime, the EPA will continue to juggle the science and politics of ethanol, an issue that will certainly get even more intense at the 2010 Congressional election approaches.

  1. What is your arguement? Do you not have regular gasoline available for your boat? Or are big oil companies encouraging you to make a fuss?

  2. You can’t buy pure gasoline, but this has nothing to do with supporting oil companies. Ethanol has proven to cause problems in engines and fuel tanks, particularly on boats, for a variety of well-documented reasons. Increasing the amount of ethanol is a likely recipe for many damaged engines.
