The U.S. Environmental Protection Agency said it needs more time to decide whether to increase the amount of ethanol in gasoline up to 15 percent.
The federal agency was supposed to release its decision Tuesday on a waiver request by Growth Energy, a pro-ethanol lobby, for higher ethanol blends, but said it needed more time to review test data, according to a report by Reuters.
A decision is expected in mid-2010, the agency said on its Web site.
The National Marine Manufacturers Association, along with numerous other groups, warn higher ethanol blends could lead to serious performance, durability and emissions problems in recreational marine engines and boats and that more testing is necessary before any increase in the ethanol blend level can be permitted.
More than 30,000 marine industry employees, boaters and others submitted comments to EPA urging the agency to deny the waiver.
