The American Fuel & Petrochemical Manufacturers (AFPM) petitioned the U.S. Court of Appeals for the District of Columbia Circuit on November 21, 2012, for review of the U.S. Environmental Protection Agency’s (EPA) 2013 biomass-based diesel renewable fuel requirements. Under EPA’s September 27, 2012, final rule, EPA increased the volume of biomass-based diesel from 1.0 billion to 1.28 billion gallons for calendar year 2013. According to AFPM, a number of factors have surfaced since EPA issued the rule that could result in unintended consequences adversely impacting the domestic refining industry and U.S. consumers. AFPM states that the increase could reduce investment in advanced biofuels that compete with biodiesel and increase carbon emissions. In addition, AFPM notes, the increase could negatively impact the price and supply of agricultural commodities, since additional biodiesel feedstocks, such as soybean oil, would be required under the rule.
