On May 21, 2014, Iowa Governor Terry Branstad (R) signed into law Senate Bill 2344, legislation to help promote the biofuels industry in the State. A copy of the legislation is available online. It extends the biodiesel production tax credit that was scheduled to expire at the end of 2014, enhances Iowa's E-15 retailer tax credit, and adds biobutanol as a renewable fuel option. This law reinforces Iowa's ongoing support for the biofuels industry.
