The Environmental Protection Agency has announced it would allow gas stations to continue selling slightly cheaper E15 this summer in a move that may be good for drivers and corn growers but will likely contribute to air pollution. The higher ethanol blend is usually limited to use in winter months. But the summer waiver for E15 has become commonplace in recent years, and both Republicans and Democrats have called for it to become year-round and permanent to lower prices at the pump. In some states it’s already allowed. But not all experts are convinced the move will substantially lower gas prices.
