"Scott Pruitt, the embattled head of the Environmental Protection Agency, faces a broadening challenge to his efforts to roll back greenhouse gas regulations, as agency science advisers expand the list of policies they want to vet at an upcoming meeting.
A work group of the EPA's Science Advisory Board has added three more of his actions to a list they want reviewed by the full board: the weakening of auto efficiency and emissions standards, Pruitt's elimination of a rule to curb truck pollution, and the cost-benefit analysis underpinning the Clean Power Plan, which the Trump administration is trying to undo.
The main purpose of the board is to review the quality and relevance of scientific research used by the EPA to draft regulations."
