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.
