A notice from the Environmental Protection Agency has the biofuels community up in arms as they face the prospect of a potential hit to renewable fuel blending levels. the EPA released a Notice of Data Availability (NODA) giving public notice and inviting comment on “potential options for reductions in the 2018 biomass-based diesel, advanced biofuel, and total renewable fuel volumes, and/or the 2019 biomass-based diesel volume under the Renewable Fuel Standard (RFS) program.” A 15-day comment period will be triggered when the NODA is published in the Federal Register. In July, the EPA announced Renewable Volume Obligations for 2018 as well as biomass-based diesel for 2019 at levels that didn’t exactly thrill biofuels supporters. The biodiesel RVO was proposed at 2.1 billion gallons, the same level proposed for 2018. That negated some of the happiness about the Trump administration leaving room for 15 billion gallons of conventional biofuel, the amount called for in the legislation that created the RFS.In the NODA, the agency discusses reductions of biomass-based diesel by 315 million gallons, lowering the advanced biofuel and total renewable fuel RVO by the equivalent of 473 million ethanol Renewable Identification Numbers, or RINs. The NODA cites concerns over biodiesel imports which it says “could affect our analysis” of factors used to set the Renewable Volume Obligations in the first place.
