WASHINGTON, D.C. — A group of Wisconsin Republican congressmen on Monday unveiled new federal legislation aimed at eliminating emissions testing requirements in southeastern Wisconsin, arguing the region is being unfairly penalized for pollution drifting in from out of state.
U.S. Reps. Bryan Steil, Scott Fitzgerald, Glenn Grothman, and Tom Tiffany announced the introduction of the “Fair Air Standards Act,” a bill designed to address southeastern Wisconsin’s longstanding classification as an ozone nonattainment area.
The designation, made under the Clean Air Act, triggers stricter federal regulations, including mandatory vehicle emissions testing for drivers in several counties. Lawmakers behind the bill argue those requirements are outdated and unfair, given what they describe as minimal in-state contributions to the region’s ozone levels.
“Families in Wisconsin shouldn’t be paying for pollution originating from outside the state, in places like Chicago,” Steil said during a press conference announcing the legislation. “This bill ensures Wisconsin’s status is tied to emissions generated here, not elsewhere.”

According to data cited by the lawmakers, state agencies including the Wisconsin Department of Natural Resources and regional planning officials have estimated that Wisconsin sources account for no more than 10% of ozone pollution measured in the affected area. The rest, they argue, drifts in from larger metropolitan regions, particularly Chicago and parts of Indiana.
Fitzgerald said the proposal would give states more authority to challenge federal designations when pollution originates beyond their borders. “This legislation will restore fairness for our region and help us move forward without unnecessary federal barriers,” he said.
Grothman framed the issue as a decades-long economic concern, arguing current regulations have placed Wisconsin industries at a competitive disadvantage. Tiffany focused on the impact to drivers, noting that hundreds of thousands of residents in seven counties must undergo emissions testing every two years as part of vehicle registration requirements.
Under the proposed law, states would be allowed to formally petition the Environmental Protection Agency to demonstrate that nonattainment status is primarily caused by out-of-state pollution. If successful, the EPA would be required to redesignate the area as being in compliance with ozone standards.
Supporters say that change would effectively end emissions testing requirements in southeastern Wisconsin and reduce regulatory burdens on businesses and residents. The bill would not otherwise alter existing air quality standards or environmental protections.
Currently, when regions fail to meet federal ozone deadlines, they are automatically reclassified into more severe nonattainment categories — a process critics say does not account for pollution sources beyond local control.
The legislation now heads to Congress for consideration, where its prospects remain uncertain amid ongoing national debates over environmental regulation and federal oversight of air quality standards.

What about the people with POS vehicles dumping fumes into the atmosphere. Emissions testing should help keep the clumpers off the streets or rt left you’d think so
One
Or two?
The bill makes sense although I agree there should be something about older vehicles.
