The US Supreme Court refused to hear a legal challenge to the U.S. Environmental Protection Agency’s E15 program.

Groups representing refiners, vehicle manufacturers, and grocery wholesalers asked the high court for a hearing after the US District Court for the District of Columbia ruled they lacked standing to challenge EPA’s action.

As you might expect, energy trade groups were not happy with the ruling, claiming the decision is a “big loss” for consumers, for safety, and for the environment.” They say E15 testing is incomplete.

Ethanol producers and trade groups were pleased, saying the 15% ethanol blend would provide consumers with more affordable choices at the pump.
