Membership in the Simple Fuels Biodiesel Users Group (BUG) is required for California customers to purchase biodiesel blends over B20 from us. This is in accordance with California Division of Measurement Standards (DMS) regulations. As biodiesel at higher blends is considered a 'developmental fuel' in California, the regulations allows for the fuel to be sold and distributed to fleets and within other approved groups. In the case of individual consumers, fuel sales will also be allowed to members of “Biodiesel Users Groups”.

To become a Simple Fuels Biodiesel BUG Member, you will need to download the Membership Agreement. You can then mail it or fax it to us (530-993-6003), or hand it off to the driver on your first delivery.

This membership is useful not only for purchasing fuel from us, but also for many other biodiesel user groups throughout California! If you have any questions about the signup process, please feel free to contact us at 530-993-6000.
