State incentives

E85 Fuel Use Incentive
A political subdivision that purchases E85 for use in flexible fuel vehicles (FFVs) may be entitled to a monthly incentive payment of $33.33 for each FFV owned fewer than five years. They are eligible if 75% of motor vehicle fuel purchases were E85 in the previous month. This incentive expires January 1, 2019. (Indiana Code 6-6-1.1-103, 8-14-2-8, and 36-1-2-13)

E85 Promotion and Education
The Indiana State Department of Agriculture must work with automobile manufacturers to improve awareness and labeling of E85 and must coordinate with the appropriate companies to include E85 fueling stations in updates of global positioning navigation software. (Indiana Code 15-11-2-4)

E85 Retail Sales Reporting
A retailer who dispenses E85 must report to the Indiana Department of State Revenue the total number of gallons of E85 sold from a metered pump. (Indiana Code 6-2.5-6 and 6-2.5-7-5)

Immunity for Misuse of E85
E85 sellers, suppliers, distributors, manufacturers, and refiners are immune from civil liability for personal injury or property damage resulting from a person fueling any vehicle with E85 that is not a flexible fuel vehicle. This includes any vehicle equipped to operate when fueled entirely with E85. This immunity does not apply if an E85 seller, supplier, distributor, manufacturer, or refiner does not display all E85 warning signs that federal or state laws require. (Indiana Code 34-30-24)

Biofuels Blend Use Requirement
Whenever possible, governmental entities and state educational institutions must fuel gasoline vehicles with mid-level ethanol blends between 20% and 73%, and flexible fuel vehicles with E85. This requirement does not apply if such blends are prohibited under federal regulations or have not been approved by the vehicle manufacturer. Additional exemptions apply. (Indiana Code 5-22-5-8, 6-3.1-27-2, and 21-31-9-3)
