"Environmental groups in Wisconsin are suing the state’s Department of Natural Resources, claiming that the agency hasn’t done its job in implementing recent federal air pollution regulations.

Clean Wisconsin and Midwest Environmental Defense Center Inc. filed a lawsuit last week that aims to force the DNR to comply with Environmental Protection Agency regulations for sulfur dioxide, nitrogen oxide and particulates (soot). The EPA updated its rules for sulfur dioxide and nitrogen oxide in 2010, and its rules for particulate matter in 2012. But according to the groups, Wisconsin hasn’t updated its statewide regulations on these pollutants.

'The protection of the federal Clean Air Act and Wisconsin air pollution statutes are not fully recognized unless and until the Department of Natural Resources undertakes is [sic] legal obligation to implement the law by updating air quality standards,' the groups write in the lawsuit. 'The DNR has failed to do so.'  "
