  • The U.S. Court of Appeals for the District of Columbia Circuit has ruled that the Environmental Protection Agency (EPA) has the “ultimate authority” to determine whether an area is in attainment with national ambient air quality standards (NAAQS) for ozone. Many industry and environmental groups, along with states and counties, were challenging nonattainment designations finalized by the EPA in May 2012.
