The Environmental Protection Agency rejected November 16 a waiver request by six states for relief from an ethanol mandate under the Renewable Fuels Standard. The states had requested that the agency waive the requirement following a drought this summer that hurt corn crops and drove up the price of feed for livestock and other agricultural uses. The agency received over 2,500 comments on the potential waiver. Immediately following the announcement, Senator Pat Toomey (R-PA) promised to challenge the agency’s decision.
