EPA can revise provisions of ozone rule — court

摘要

A federal appellate court has given U.S. EPA a do-over on parts of a rule setting requirements for states to meet the 2008 air quality standard for ozone. The rule, put in place early last year, is being challenged by the Sierra Club and other environmental groups in part on the grounds that it gives states too much leeway in meeting the 2008 limit (Greenwire, May 13, 2015). In an order yesterday, the U.S. Court of Appeals for the District of Columbia Circuit granted EPA's unopposed motion to revise several "antibacksliding" provisions related to both the 2008 ozone standard and the previous benchmark set in 1997.
