EPA Says Ethanol Bounty May Push Refiners Over Blend Wall

Refiners may be forced to exceed 10 percent ethanol in their fuels next year in order to meet congressionally mandated renewable-fuel standards, according the Environmental Protection Agency.

While oil-industry lobbyists are urging lawmakers to scrap the Renewable Fuel Standard because of problems this year, an EPA official will tell Congress today that issues with the “blend wall” -- where the amount of mandated corn-based fuel exceeds levels considered safe for all engines -- won’t bite until 2014.
