The Nickel Report

On April 11, 2017, the United States Court of Appeals for the District of Columbia Circuit canceled oral argument, which had been scheduled for April 19, in several consolidated cases challenging EPA’s 2015 revision of National Ambient Air Quality Standards (NAAQS) for ozone. The court took this action, and ordered that the case be held in abeyance, in response to an EPA motion asking that oral argument be continued, to give the appropriate Trump administration officials adequate time to review those standards. EPA’s motion indicated that the new administration is deciding whether to reconsider them.
