 “This legislation would invest significantly into Iowa’s renewable fuel infrastructure program, boost farm income, reduce emissions, and put millions of dollars back into the state’s general fund. It is time for Iowa to take charge of our renewable fuel economy and stand up against the inconsistency we continue to see from Washington, D.C., and the (federal Environmental Protection Agency).”-- Sioux City Journal, February 14, 2021  Gov. Kim Reynolds 

 Iowa Biofuel Standards Bill Overview  B11/20 Fuel Standard – All diesel in the state to include biodiesel as seen below.B5 during winter months (October to March)B11 during summer months (April to September 2022-2023)B20 during summer months (2024 and later) 

 Iowa Biofuel Standards Bill Overview  E10 Fuel Standard – “All” gasoline in the state to include at least 10% ethanol.Exemptions for one pump per retailer for small and off-road engines, old cars, and marinas.New state label for E0 highlighting these restrictions. 

 Iowa Biofuel Standards Bill Overview  E15 Fuel Standard Trigger – Would change the E10 standard to E15 standard.On January 1, 2025, the Governor will have the option to move to a E15 standard. If retail infrastructure constraints exist, the Governor can delay the date. 

 Iowa Biofuel Standards Bill Overview  Renewable Fuel Infrastructure Program Funding – increase from $3M to $10M year for retailer grantsLimits biodiesel grants to “historical” $1.25 million per year to ensure funding for E15 infrastructure. 

 Iowa Biofuel Standards Bill Impacts  More fuel choices for consumers – E15Saves consumers 5-10 cents per gallonMore grant funding for retailers to add E15Elimination of tax credits on “standard” fuel will save Iowa taxpayers $180M over first five yearsBoost Iowa GDP by ~$450M, Support an additional 3,500 jobs, add $550M to Iowa household income
