Petroleum terminals in Texas, New York and Michigan have announced the availability of pre-blended biodiesel within the last month, according to a release from the National Biodiesel Board. Distribution Drive, a wholly owned subsidiary of Earth Biofuels, Inc. and Motiva Enterprises, an oil company headquartered in Houston, Tex., announced Monday that the Motiva Enterprises terminal in Dallas will now offer biodiesel at any blend level. That’s the one that got all the media attention this week, since it’s in “big oil” country. The others that opened with less fan fare were Sprague Energy in Albany, NY and RKA Petroleum Cos. in Romulus, Michigan.
