Just as the EPA started its 30-day comment period on a waiver request for the Renewable Fuel Standard, the National Corn Growers Association is asking for more time for comments. NCGA President Garry Niemeyer sent a letter to EPA Administrator Lisa Jackson requesting an additional 30-day extension, citing harvest and the uncertainty of this year’s corn crop:

“Across the nation our members are beginning harvest, one of the busiest times of the year,” Niemeyer wrote. “Given the demands of harvest, I am concerned that the proposed 30-day comment period will not provide sufficient time for a thorough analysis of the proposed waiver and would hinder farmer participation in this important policy process. Also, with the crop still in the field, it is too early to determine this year’s final corn supply.”

As it stands now, the comment period closes at the end of September. Then, the EPA has two more months to make its decision. Four years ago, Texas Gov. Rick Perry requested a partial waiver of the RFS, which was denied by the EPA. That request generated 15,000 comments.
