Biodiesel Blend Standards

Biodiesel blends are considered compliant with Texas Low Emissions Diesel Fuel (TxLED) regulations if the diesel fuel is compliant with TxLED regulations and the biodiesel meets the requirements of ASTM specification D6751. Biodiesel may be added to any TxLED compliant fuel at any ratio without additional additives. Biodiesel blenders are not considered diesel fuel producers and are not subject to TxLED reporting requirements. However, blenders must maintain records of product transfer documents and make them available upon request to the Texas Commission on Environmental Quality, U.S. Environmental Protection Agency, or local air pollution authority for a minimum of two years.
