Today is the last day of the comment period on the petition to the U.S. Environmental Protection Agency requesting a waiver to allow ethanol gasoline blends of up to 15 percent.
The comment period was slated to end May 21, but the additional time allowed boaters, marine industry employees and other concerned parties more time to submit comments to the EPA.
Growth Energy, a pro-ethanol lobby, is the group that requested the waiver.
The National Marine Manufacturers Association, and other industry stakeholders, have called for a science-based review of the request by the EPA in order to ensure that increased levels of ethanol would not harm boats, marine engines and other affected equipment.
The EPA has said it is required to make a decision by Dec. 1.
