Ive heard reports of low-quality biodiesel damaging vehicles. What is EPA doing to ensure biodiesel quality?
Generally speaking, biodiesel purchased from a reputable dealer selling commercial-grade biodiesel should be of good quality. Each manufacturer of biodiesel is required to be registered by the EPA. As part of the registration process, the manufacturer provides evidence that it can produce biodiesel that meets standards set by ASTM, a group whose fuel standards are almost universally recognized by government entities in the United States. In addition, the National Biodiesel Board, the national trade association for biodiesel producers, has a voluntary accreditation and quality assurance program called BQ-9000. It is managed by an independent organization, the National Biodiesel Accreditation Commission, and certifies biodiesel producers and distributors. For more information, please visit: www.b1-9000.org.
