Nineteen livestock, poultry, and dairy industry groups petitioned the Environmental Protection Agency July 30 to waive for one year the requirements of the renewable fuel standard because the recent drought has reduced corn production, thus increasing corn prices by 40 percent since June. Senator Kay Hagan (D-NC) is leading a letter to Administrator Lisa Jackson requesting a waiver because of the conditions. The agency is requiring 15.2 billon gallons of renewable fuels in the country’s fuel supply this year.
