Trump administration to deny pending retroactive U.S. biofuel waivers, sources say

U.S. President Donald Trump has instructed that dozens of oil refiner requests for retroactive waivers from U.S. biofuel laws be denied amid concerns the issue could cut into his support in the Farm Belt, three sources familiar with the decision said. The move, in the form of a direction to the Environmental Protection Agency, marks the end of an effort by the refining industry to come into compliance with a January court decision that said the Trump administration should not have given out some waivers in previous years.
