In February 2025, the United States Environmental Protection Agency announced it will delay the addition of nine per- and polyfluoroalkyl substances (“PFAS”) to its Toxics Release Inventory Report for the 2025 reporting year. “PFAS” is a term used to describe a diverse group of chemicals contained in many consumer products and industrial processes. The EPA’s announcement followed President Trump’s January 2025 memorandum “Regulatory Freeze Pending Review” which, among other things, requested a 60-day postponement “to the effective date memorandum for any rules that have been published in the Federal Register, or any rules that have been issued in any manner but have not taken effect, so that the administration may review any questions of fact, law, and policy that the rules may raise.” Accordingly, impacted industries now have additional time to prepare for new PFAS reporting requirements under the Emergency Planning and Community Right-to-Know Act (“EPCRA”) and the Pollution Prevention Act (“PPA”) following the addition of nine PFAS chemicals to the Toxics Release Inventory (“TRI”).

On October 18, 2021, the U.S. Environmental Protection Agency (“EPA”) issued its highly anticipated PFAS Strategic Roadmap: EPA’s Commitments to Action 2021-2024, setting forth a three-year multi-agency strategy to address per- and polyfluoroalkyl substances (“PFAS”). The plan outlines actions that will fundamentally alter the administrative landscape around PFAS.

On January 25, 2018, the U.S. Environmental Protection Agency (“EPA”) withdrew its 1995 “once in always in” guidance. Under that guidance, facilities classified as “major sources” of hazardous air pollutants (“HAP”) as of the “first compliance date” of a maximum achievable control technology (“MACT”) standard under Section 112 of the Clean Air Act are required…

On December 4, 2017, the Wisconsin Department of Natural Resources (DNR) amended its National Ambient Air Quality Standards (NAAQS) for fine particulate matter (PM2.5). The rule reduces the primary annual standard for PM2.5 from 15.0 to 12.0 micrograms per cubic meter (µg/m3). DNR was required to promulgate this rule to be consistent with the U.S. EPA NAAQS for PM2.5, published in January, 2013. The DNR rule is scheduled to be effective January 1, 2018, and will be submitted to the EPA as a revision to the Wisconsin state implementation plan.

Although one of these developments may provide a degree of regulatory relief, the other two may preserve or even strengthen existing regulatory requirements.
