On March 13, 2017, the South Dakota Farmers Union announced that the National Farmers Union had passed a resolution calling for the U.S. Environmental Protection Agency (EPA) to open the market to higher blends of ethanol during its annual meeting in San Diego. The resolution, which was brought forward by the South Dakota Farmers Union delegation, promotes the use of higher blended fuels, such as E30, as a way to expand the retail fuels infrastructure and support the Renewable Fuel Standard (RFS).

In addition to passing the resolution, the National Farmers Union filed legal comments regarding EPA’s overreach in its interpretation of the Clean Air Act (CAA), which limits ethanol content to 15 percent. Doug Sombke, President of South Dakota Farmers Union, called on EPA and all government regulators to reverse statements and policies that unfairly limit the amount of ethanol in fuel and stated that both the state and national organization continue to seek greater market access for higher blended fuels.
