President Trump’s decision last week to allow the year-round sale of E15 is a promise made and kept to farmers throughout rural America. E15 is shorthand for gasoline blended with 15% ethanol, instead of the more common E10, and was prohibited for sale in the summer by the Environmental Protection Agency in 2011.Biofuels are a part of everyday life in Iowa, the top corn-and ethanol-producing state in the U.S. Ethanol supports more than 43,000 Iowa-based jobs and 350,000 jobs throughout the country, directly and indirectly. Ethanol contributed $44.4 billion to gross domestic product and $5 billion in federal tax revenue in 2017.Year-round E15 sales will bring increased stability to the market and create new growth opportunities. Today only about 1,400 out of 122,000 filling stations in the U.S. sell E15. That’s a result of the Obamaera regulation, not a lack of consumer demand. With filling stations prohibited from selling higher-ethanol blends for nearly a third of the year, it often didn’t make economic sense to install the infrastructure necessary to sell the product at all. That will change after the implementation of year-round E15.The change couldn’t come at a better time. Farm income is down 47% over the past five years. The U.S.-Mexico-Canada agreement will help, but there’s still unrest in America’s heartland about trade negotiations between the U.S. and China. The administration’s E15 action will deliver a timelyinfusion of optimism to farmers. It will also put an end to an unnecessary government regulation that hinders consumer choice at the pump.
