The U.S. Environmental Protection Agency is looking into
what might happen to the environemnt if the maximum level of ethanol mixed into the national liquid fuel supply is increased from 10 percent (where it is today) to 15. This is raising all sorts
, as we've pretty much described to death recently. It looks like the EPA is dealing with a lot of information on the subject, too (or, maybe, not enough), and today the Agency extended the public comment period by 60 days. The whole discussion was kicked off by an application submitted in early March by Growth Energy and 54 ethanol manufacturers asking for a waiver to up the blend to E15 (more details here
). The EPA needs to decide on the waiver request by December 1, and the extension of the public comment period will not change that deadline.
