The U.S. EPA on Friday backed away from its previously mandated targets for U.S. biofuel production by relaxing the proposed levels of ethanol use outlined in its Renewable Fuel Standard, to address the “E10 blend wall.” The proposal would set ethanol use at 15.21 billion gallons — just under 10 percent of motor-fuel consumption and 16 percent lower than targets established by Congress in 2007 — and also called for public input on the levels of renewable fuels to be blended into gasoline and diesel as required by Congress under the Energy Independence and Security Act of 2007.
