How much corn is in your boat’s gas tank?

The Renewable Fuel Standard is the 2005 federal law that requires the blending of biofuels such as corn-ethanol into our gasoline. When it was written, it assumed that America’s use of gasoline would continue to rise and mandated escalating amounts of biofuels to be blended with our fuel.

Since 2005, however, gasoline usage has actually declined steadily, which today forces more ethanol into less gasoline.

The Environmental Protection Agency is asking for comments on a proposal to increase the amount of ethanol that must be blended into the nation’s fuel supply for 2015 and 2016.

If adopted, these proposed levels will require the use of a record amount of ethanol, forcing higher-level fuel blends (including E15) into more gas stations.

BoatUS urges recreational boaters to send a message to the EPA now by going to and demand that the agency lower the ethanol mandate to ensure an adequate supply of safe fuel. Comment deadline is July 27.
