"A federal appeals court today threw out U.S. EPA's decision to extend a compliance deadline for its ozone air standard, as well as the agency's revoking a stringency requirement for transportation projects.

In both instances, the U.S. Court of Appeals for the District of Columbia Circuit ruled that EPA's actions exceeded its authority under the Clean Air Act.

The case brought by the Natural Resources Defense Council concerned what amounted to a compliance extension built into EPA's 2008 National Ambient Air Quality Standard for smog-causing ozone."
