Ethanol Fueling Infrastructure Development
E10 (10% ethanol, 90% gasoline) is available at nearly every fueling station. There are more than 4,200 public stations in 44 states offering E85 (or flex fuel)—a gasoline-ethanol blend containing 51% to 83% ethanol, depending on geography and season. As of 2022, E15 was sold at more than 2,500 stations in 31 states. Some stations offer multiple ethanol blends at one location, often through blender pumps.
To learn about installing infrastructure for blends above E10, see:
Identify which codes, standards, and safety measures must be followed for underground storage tanks (USTs) containing ethanol blends above E10.
Learn what refueling equipment is necessary to deliver ethanol fuel to vehicles.
Determine which permits are required, and which regulations must be met, to install ethanol equipment.
