(NAFB.com) – A broad coalition of energy and agriculture organizations wrote a letter to Congress asking them to adopt legislation that would resolve inconsistent fuel volatility regulations. Specifically, the groups expressed support for legislation that would result in equal regulatory treatment for all gasoline blends containing ten percent ethanol or more, including gasoline with a 15 percent blend of ethanol.

Such legislation would permanently remove the regulatory barrier that has historically made it extremely difficult for retailers to offer E15 in the summer. “Our groups have come together for the first time in history to support legislation that will permanently resolve the issue,” the letter says. “By ensuring uniformity across the nation’s fuel supply chain, that will provide more flexibility and result in more consistent outcomes than a state-by-state regulatory landscape.”

Without the fix, the groups see gasoline marketplace uncertainty and political disputes over E15 that will continue to resurface every summer.
