More than 22,000 people have e-mailed President Barack Obama, urging him to stop the Environmental Protection Agency from approving a 50 percent increase in the amount of ethanol in gasoline, according to the National Marine Manufacturers Association.
The NMMA and others, including the Marine Retailers Association of America and BoatU.S., want to see any decisions on E15 delayed until scientific testing shows whether higher ethanol levels will increase air pollution, harm engines or raise consumer safety issues.
"Due in no small part to your help, a majority of these e-mails were generated by those in the boating community," the NMMA said. "Thank you for your efforts to help us spread the word.
The NMMA encourages people to visit www.FollowTheScience.org to write an e-mail to the president.
A decision by the EPA is expected on or about Oct. 15.
