Ethanol Fueling Infrastructure Development
E10 (10% ethanol, 90% gasoline) is available at nearly every fueling station. The number of stations offering E85 (or flex fuel)—a gasoline-ethanol blend containing 51% to 83% ethanol, depending on geography and season—is smaller but continues to grow. As of 2019, E15, a relatively new ethanol blend, was sold at more than 1,700 stations in 30 states. Some stations chose to 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.
