"The Trump administration has walked away from a chance to appeal a court decision on its refinery waiver program, delivering a win to ethanol producers while angering oil refiners.
The 10th Circuit Court of Appeals had ruled that the Environmental Protection Agency’s (EPA) program, which grants economic hardship waivers to small oil refineries that are otherwise required to blend ethanol into their supply, shortcut national goals for ethanol use.
The Trump administration had previously asked for a two-week extension to file an appeal to the case, but ultimately filed nothing before the midnight Tuesday deadline."
