Speak Up on the Federal Ethanol Mandate - Comment Now

RBOC joins our national partner BoatU.S. in asking boaters to comment today:

The battle to protect your boat’s engine is not over. Right now, the Environmental Protection Agency (EPA) is asking for comments on the amount of ethanol that must be blended into the nation’s fuel supply for 2018.

Boat owners need to speak up and be heard by the EPA. 

While the proposed national ethanol levels are slightly lower than the 2017 mandate, boaters can expect to face higher ethanol-blend fuels, such as E15 (15 percent ethanol), at more gas stations next year under the current proposal. Because of its ability to damage boat engines, federal law prohibits the use of gas blends greater than E10 (10 percent ethanol) in recreational boats.

Please take a few moments to send a message NOW urging the EPA to lower the ethanol mandates to ensure an adequate supply of fuel that will work in your boat.

The Renewable Fuel Standard (RFS) is the 2005 law that requires the blending of biofuels such as corn-ethanol into our gasoline. To meet this government mandate, in 2010 the EPA permitted E15 (fuel containing up to 15 percent ethanol) into the marketplace, but only for model year 2001 or newer automobiles. Using E15 in marine engines as well as snowmobiles, motorcycles, and small engines, like lawnmowers and leaf blowers, is prohibited. In addition, it has been proven that E15 will damage boat engines, making it vital that E10 and ethanol-free gasoline is readily available.

E15 and higher ethanol-blend fuels can now be found in at least 23 states, often at the very same pumps as E10 gasoline. A single sticker on the pump mixed in with all the other labels may be the only warning of E15 gasoline. This creates a dangerous potential for misfueling and puts boaters at risk of using fuel that will damage their engines. CLICK HERE for more information on E15 and the Renewable Fuel Standard.

Thanks for taking action to let EPA hear how ethanol will affect your boat engine. BoatU.S. members have one of the largest voices on this issue in Washington so please send your comments today and share this email with your boating friends.

The comment period ends on August 31st so please send your comments today.
