approved by EPA for 2001 and newer vehicles, even though these vehicles were designed, built, and warranted to operate on a maximum blend of E10. A recent study found that E15 could indeed damage the engines of some cars and light trucks -- perhaps millions of them on America's roads today -- as well as lawnmowers, boat engines and other consumer equipment. EPA dismissed concerns of auto makers and the oil and natural gas industry, pushing a fuel into the marketplace to help satisfy the RFS' mandate for blending increasing volumes of ethanol into gasoline. Another problem with the RFS is its mandate that oil refiners blend 8.65 million gallons of cellulosic ethanol into the fuel supply by the end of the year -- despite the fact no one is producing this advanced form of ethanol commercially. Instead of completely waiving the provision, EPA denies reality and is making refiners buy credits for a non-existent fuel, effectively an added tax on making gasoline. Congress needs to address that issue, as well as fraud surrounding renewable fuel credits some refiners have bought under a program created by EPA. These refiners became fraud victims after buying invalid credits in good faith. EPA's initial response? Sorry, that's your problem -- here is your fine, and you also need to buy more credits. Again, this becomes an added cost to making gasoline. Our industry is trying to work with EPA on this issue, but congressional action might be necessary if EPA fails to act
