On July 3, 2026, the Office of Management and Budget published the Trump Administration’s 2026 Unified Agenda, outlining a broad set of regulatory actions on per- and polyfluoroalkyl substances.
The U.S. Environmental Protection Agency’s portion of the agenda covers ten distinct PFAS-related rulemakings spanning drinking water, wastewater, chemical reporting, and hazardous waste regulations.
Under the Clean Water Act, EPA is revising effluent limitations guidelines to address PFAS discharges from facilities that manufacture PFAS within the Organic Chemicals, Plastics and Synthetic Fibers point source category.
EPA intends to publish a notice of proposed rulemaking for that effluent guidelines revision in July 2026, though it has not yet determined when a final rule will follow.
A separate rulemaking targets chromium electroplating facilities, with EPA revising Metal Finishing Effluent Limitation Guidelines to address PFAS discharges in wastewater, with a proposed rule expected in February 2027.
EPA is also moving to update National Pollutant Discharge Elimination System permit application requirements, noting that the current list of pollutants subject to reporting has not been updated since 1987 and does not include PFAS.
That NPDES rulemaking seeks to require monitoring and reporting of PFAS, with a proposed rule planned for January 2027 and a final rule targeted for May 2027.
On drinking water standards, EPA proposed on May 20, 2026, to extend compliance deadlines for Maximum Contaminant Levels covering perfluorooctanoic acid and perfluorooctane sulfonic acid, with a final rule expected in July 2026.
EPA stated it intends to address “the most significant compliance challenges the Agency has heard from public water systems and other stakeholders while still ensuring the long-term protection of the American people from PFAS-contaminated drinking water.”
Also on May 20, 2026, EPA proposed to rescind its regulatory determinations for four PFAS substances, including perfluorohexane sulfonic acid, perfluorononanoic acid, HFPO-DA commonly known as GenX, and a mixture including perfluorobutane sulfonic acid, with a final rule targeted for September 2026.
Under the Resource Conservation and Recovery Act, EPA is working toward a final rule to add nine specific PFAS and their structural isomers to its list of hazardous constituents, with that final rule expected in January 2027.
EPA is also considering revisions to its Toxic Substances Control Act PFAS reporting rule, which currently requires manufacturers and importers of PFAS from 2011 to 2022 to report data on exposure and environmental and health effects, with a final rule expected in July 2026.
EPA states it “plans to propose the incorporation of certain exemptions and other modifications to the scope of the reporting rule” as part of that TSCA revision process.
Two additional rulemakings address the Toxics Release Inventory, with EPA developing final actions to add PFAS to the TRI list under the Emergency Planning and Community Right-to-Know Act, and making conforming edits to reflect automatic additions of PFAS under the National Defense Authorization Act for Fiscal Year 2020.
EPA issued a final rule on February 27, 2026, amending the codified TRI chemical list to reflect automatic PFAS additions, continuing a practice it has carried out each year since 2020.
