E85 is a nominal blend of 85 percent ethanol and 15 percent gasoline that is an alternative fuel for automobiles. The actual ethanol content of E85 can vary depending upon the month of the year and geographical location, and may be as little as 70 percent ethanol. E85 is used in flexible fuel vehicles (FFVs). The Board approved the alternative fuel specifications, including E-85 Fuel Ethanol, by adopting Resolution 92-9 at a public hearing on March 12, 1992. The Executive Officer subsequently issued Executive Order G-775, adopting several sections including 2292.4, Title 13, California Code of Regulations. The growing use of E85 has prompted a review of the specifications which have not been updated since originally adopted.
