On October 3, 2016, the U.S. Environmental Protection Agency (EPA) released the proposed Renewables Enhancement and Growth Support Rule. This proposed rule includes suggestions to improve the Renewable Fuel Standard (RFS) program and related pro-renewable fuel regulations. Updated regulations included in the proposed rule include allowing biofuel producers to process feedstock and then convert the material into fuels at different facilities, and an expansion to the availability of high-ethanol fuel blends. The proposed rule allows increases to the types of feedstocks that biofuels can be produced from, allowing cellulosic biofuels to be produced from short-rotation poplar and willow trees; renewable diesel and biodiesel to be produced from non-cellulosic portions of separated food waste; and cellulosic diesel to be produced from compressed cellulosic feedstocks and petroleum. Comments will be due 60 days after the proposed rule’s publication in the Federal Register.
