The MSDS shows Biodiesel is not regulated by USDOT as a hazardous material. Diesel fuel/fuel oils blended with the Biodiesel material are shipped at several different and 80% fuel oil. Data received by my office indicates the blended products have flash blending rates. B-2 is 2% Biodiesel and 98% fuel oil/diesel fuel. B-20 is 20% Biodiesel points that would make them flammable liquids or combustible liquids by USDOT definitions. information that some of the blended products are being shipped and transported with The fuel oils and Biodiesel are splash blended and then distributed. My office has shipping papers showing a hazardous materials description for diesel fuel or fuel oil or the first line, and the entry Biodiesel or Fatty acid esters on a second line. There is no indication on the document that the product is a blend of the two materials. The blended materials are shipped and transported in cargo tanks. If the blended materials are a solution of a hazardous material and a non-hazardous material, should the proper shipping name be diesel fuel solution or fuel oil solution, as required in 49 CFR 172.101 (c) (10)?
