North Carolina has been inappropriately blamed for contributing to air quality problems in the Northeastern part of the U.S. That’s the position of the state’s environmental agency, which has filed a complaint against federal officials. Northeastern states filed a petition in December of 2013 to try to force some other states to control their emissions. The EPA has yet to take action on the petition. A lawyer from North Carolina’s Department of Environment and Natural Resources says that’s a violation of the Clean Air Act. The agency is suing the EPA and says the Northeastern states failed to demonstrate that North Carolina’s power plants had any impact in the Northeast.
