"As the worst drought in more than 50 years withers the Midwest corn crop, 25 senators urged the Environmental Protection Agency to cut the mandate that requires fuel blenders to add grain-based ethanol to gasoline."

"The senators representing 25 percent of the chamber urged EPA chief Lisa Jackson to adjust the Renewable Fuels Standard, or RFS, that requires fuel blenders to mix 13.2 billion gallons of ethanol into gasoline this year.

The mandate rises steadily until peaking at 15 billion gallons per year in 2015 and holding that level through 2022."
