A new bill introduced by Republicans in Wisconsin would allow Wisconsin to designate areas that are not meeting federal smog regulations if it can prove most pollution is coming from outside the state. The Fair Air Standards Act would allow the state to blame other states for its smog problem, including Illinois and Indiana. The bill is part of a broader effort to bring Wisconsin closer to ground-level ozone standards updated by the Obama administration in 2015. Critics argue that it will not improve air quality for children and those suffering health impacts from ozone pollution. The Environmental Protection Agency has designated seven southeastern Wisconsin counties in “nonattainment” or not meeting national air quality standards for ozone pollution, which could cost businesses as much as $9 million. The state’s governor may submit evidence that an area would meet ozone limits if not for outside sources, and the EPA administrator could deny any redesignation. The legislation comes amid years of legal challenges and regulatory efforts to bring the state in line with ground-levels ozone standards.
