On April 7, the Renewable Fuels Association submitted comments to the Environmental Protection Agency (EPA) on the proposed cellulosic ethanol blending requirement. The group supported the reduction of this requirement, which is currently set at 14 million gallons for 2013; the petroleum industry previously called for the reduction. The comment cited the most recent projections of actual production of cellulosic ethanol. Both the Renewable Fuels Association and the petroleum industry also called for a reduction in the advanced biofuels requirement. The 14 million gallons of cellulosic ethanol is part of the 2.75 billion gallon advanced biofuel mandate; the total renewable fuels standard, which also includes ethanol, requires 16.55 billion gallons of renewable fuel to be blended in 2013.
