US Proposes Rule on Renewable Fuel Standard Program



In this proposed rule, the Environmental Protection Agency (EPA) is providing an opportunity to comment on an analysis of the lifecycle greenhouse gas (GHG) emissions associated with certain biofuels that are produced from grain sorghum oil extracted at dry mill Ethanol plants at any point downstream from sorghum grinding, also known as distiller sorghum oil.

EPA seeks comment on its proposed assessment that using distillers sorghum oil as feedstock results in no significant agricultural sector GHG emissions; and that biodiesel and heating oil produced from distillers sorghum oil via a transesterification process, and renewable diesel, jet fuel, heating oil, naphtha, and liquefied petroleum gas (LPG) produced from distillers sorghum oil via a hydrotreating process, would meet the lifecycle GHG emissions reduction threshold of 50 percent required for advanced biofuels, and biomass-based diesel under the Renewable Fuel Standard program.

Based on these analyses, EPA is proposing to amend the RFS program regulations to define the term "distillers sorghum oil". We also propose to add to the regulations approved pathways from the production of biodiesel and heating oil from distillers sorghum oil via a transesterification process, and renewable diesel, jet fuel, heating oil, naphtha, and liquefied petroleum gas (LPG) produced from distillers sorghum oil via a hydrotreating process.
