Over the past 30 years, ethanol spills have increased tenfold as production and transportation of the biofuel has spiked.

Between 2011 and 2015, ethanol spills occurred between 607 and 741 times each year nationwide, about two a day on average. Some spills caused millions of dollars worth of damages and lead to significant injury and loss of life. Spills occur on the West Coast and the East Coast and everywhere in between. They happen near cities and in rural areas. They happen by truck and by rail.

"As more and more ethanol is being transported, more and more accidents are going to occur. The potentials for different kinds of accidents are getting higher and higher."

Mark Clapp, Illinois Fire Service Institute
