The Oxygenate Blender Certification Program, defined by Title 13, CCR, Section 2266.5(g), was created to ensure that gasoline blendstock, known as CARBOB, complies with the standards for California Gasoline. To obtain certification, an oxygen blender is required to provide the facility name and the physical location of records, contact name and telephone number for each blending facility.
