EPA Reconsiders Wisconsin Ozone Rules | Milwaukee News

The EPA is reconsidering stricter ozone pollution rules for southeast Wisconsin, after state leaders and business groups argued the regulations unfairly target local sources—claiming much of the pollution drifts in from other states. While statewide ozone levels have dropped 20% over two decades, progress has stalled amid rising energy demands, including from data centers. The agency recently upgraded Milwaukee, Sheboygan, and Kenosha to “Serious” nonattainment status, triggering tougher regulations—but a federal appeals court temporarily blocked them, giving the EPA time to reassess. Business advocates support clean air but want accountability where pollution truly originates, while health experts stress that ozone harms everyone regardless of origin—and climate change will only make it worse.
