President Barack Obama’s plan to curb greenhouse gases ignited a firestorm of criticism from business interests that criticized the potential costs of the new regulations.
Now, the next battle is underway.
The U.S. Environmental Protection Agency is expected to soon unveil new rules that would require reductions of ground-level ozone — a summertime pollutant that causes smog and is known to harm human health.
The effect for southeastern Wisconsin: Many counties now in compliance with the standard for ground-level ozone would likely violate a more stringent ozone standard.
Business groups oppose the ozone regulations, and a national manufacturing group rolled out an ad campaign in Wisconsin on Wednesday, saying the new law will “stifle the economy and kill millions of jobs.”
