The Environmental Protection Agency (EPA) has approved higher blending rates for ethanol in gasoline for 2007 and newer vehicles, allowing mixtures with up to 15% of the corn-based fuel at the pump. The current maximum ethanol blend rate is 10%; a mid-level blend rate increase of 12% had been discussed in recent months.

Critics contest that the increased diversion of corn into ethanol is making animal feed more expensive.
