States file opening brief in federal ozone rule challenge


April 26, 2016

MADISON A group of states has filed its opening brief in a federal lawsuit challenging the Obama administration's new ozone limits.

The U.S. Environmental Protection Agency tightened the limits on ozone, a smog-forming pollutant linked to asthma and respiratory illness, to 70 parts per billion in October. A coalition of states including Wisconsin, Arizona, Kentucky, New Mexico, Arkansas, Louisiana, North Dakota, Oklahoma, Utah and Texas filed a federal lawsuit later that month challenging the rules.

The states filed their first brief with the U.S. Court of Appeals in Washington, D.C., on Monday arguing that the standards are unachievable and would require stopping human activity across large parts of the country, amounting to an abuse of agency discretion.

Federal attorneys have until July 22 to respond.
