On April 22, 2014, the U.S. Environmental Protection Agency (EPA) signed off on a Direct Final Rule requiring petroleum refiners and importers to blend 810,185 gallons of cellulosic fuels into the fuel supply in 2013 in response to petitions for reconsideration of the Final Rule from the American Petroleum Institute (API) and the American Fuel & Petrochemical Manufacturers (AFPM). The pre-publication version of the Direct Final Rule is available online. Petitioners successfully argued that cellulosic fuel production was well below EPA's projections. Previously, EPA had mandated that the petroleum industry blend six million gallons of cellulosic fuels into the fuel supply under the Renewable Fuel Standard (RFS) for 2013. EPA granted the motion for reconsideration because one of the two companies that EPA expected to produce cellulosic biofuel in 2013 announced shortly after EPA signed the final rule that it intended to produce significantly lower volumes of cellulosic biofuel in 2013 that it had reported to EPA. The rule will be effective 60 days after it is published in the Federal Register.
