Kim Reynolds has introduced a bill to set a minimum standard of biofuels in the Iowa fuel supply. Meanwhile, legislators at the national level are also working to streamline regulatory requirements for higher ethanol blends. In Iowa, HSB 185 proposed by Reynolds, creates more opportunities and markets within Iowa for corn-based ethanol including significant funding for biofuels infrastructure, as well as an E10 standard. The bill introduced in the Iowa state legislature would move the state to overall higher biofuel blends, including offering E15 statewide by 2025 and updating the E15 promotion tax credit to $0.03 per gallon year-round. It is estimated that over the first five years, the legislation would increase ethanol demand by over 117 million gallons.
