"15 States Appeal EPA Delay Of Stricter Air-Quality Standards"

"WASHINGTON — Attorneys general from 15 states filed a legal challenge on Tuesday over the Trump administration’s delay of Obama-era rules reducing emissions of smog-causing air pollutants.

The states petitioned the U.S. Court of Appeals for the D.C. Circuit to overturn Environmental Protection Agency Administrator Scott Pruitt’s extension of deadlines to comply with the 2015 Ozone National Ambient Air Quality Standards.

Pruitt announced in June he was extending the deadlines by at least one year while his agency studies and reconsiders the requirements. Several pro-business groups are opposed to the stricter rules, including the American Petroleum Institute, the American Chemistry Council and the U.S. Chamber of Commerce."
