Air Plan Approval; Wisconsin; Moderate Attainment Plan Elements for Wisconsin's 2015 Ozone Standard Areas
What happened
The U.S. Environmental Protection Agency (EPA) approved parts of Wisconsin's State Implementation Plan (SIP) for 2015 ozone standards in Kenosha County, Milwaukee, and Sheboygan County. This includes plans for reasonable further progress, motor vehicle emission budgets for 2023, and inspection/maintenance programs. The EPA also approved the base year emissions inventory. This final rule is effective on September 21, 2026, and was signed by Donald Trump.
Why it matters
This action formalizes Wisconsin's strategy to meet federal ozone air quality standards in specific areas. By approving these plans, the EPA is validating the state's approach to reduce harmful air pollutants from sources like vehicles. The approval of motor vehicle emission budgets will guide future pollution control efforts.
