WASHINGTON (AP) — The Supreme Court has rejected challenges to Environmental Protection Agency decisions allowing an increase in ethanol content in gasoline.

The justices on Monday left in place a federal appeals court ruling that dismissed challenges by trade associations_representing the oil industry, food producers, restaurants and others_to EPA decisions allowing a gasoline blend of up to 15 percent ethanol. The national gasoline supply is largely a blend with 10 percent ethanol.
