Yes. As a fuel vendor or Marketer you are required to keep the last three invoices, bills of lading, shipping paper or other documentation for each product being sold to comply with the Renewable Fuel Standard. This documentation must state the number of gallons and biodiesel blend you received. In addition, for the biodiesel blended products you sell, you are required to keep the last three Certificates of Analysis stating the biodiesel product meets ASTM quality standards (D 6751).
Your fuel distributor should provide you with all of this documentation upon delivery of the product. For more information on documentation requirements, see the Renewable Fuel Standard Administrative Rules.
