E15 ethanol fuels took one step closer to commercial availability today. The U.S. Environmental Protection Agency (EPA) approved health effects testing on E15 fuel submitted by the Renewable Fuels Association (RFA) and Growth Energy.

Health effects testing is a required step in the approval of any new fuel or fuel additive. With EPA’s acceptance of the results of the testing submitted by the ethanol groups, suppliers of ethanol and E15 are now able to register with EPA to offer the fuel. This is not the green light for E15 sales yet, but the health effects testing is a significant milestone to have passed.

EPA concluded, “Our evaluation therefore concludes that RFA/Growth Energy has submitted data and analysis that would satisfy the Tier 1 and Tier 2 testing requirements for registration.”
