The PFAS Compliance Calendar: What’s Coming and When
PFAS regulation is moving on multiple fronts simultaneously—federal EPA, EU, state governments, and international bodies are all advancing PFAS standards on overlapping timelines. Tracking these regulatory milestones and compliance deadlines is essential for water utilities planning treatment infrastructure, manufacturers assessing product reformulation timelines, and compliance professionals managing multi-jurisdictional PFAS programs. This consolidated regulatory calendar covers the most significant PFAS regulatory actions expected from 2024 through 2029 and beyond.
2024: The Regulatory Watershed Year
April 2024: EPA finalizes National Primary Drinking Water Regulation (NPDWR)—MCLs of 4 ppt for PFOA and PFOS; 10 ppt for PFNA, PFHxS, and HFPO-DA (GenX); Hazard Index approach for mixtures. April 2024: EPA designates PFOA and PFOS as CERCLA Hazardous Substances—strict liability for cleanup at contaminated sites. 2024: EPA finalizes Effluent Limitation Guidelines (ELGs) for PFAS manufacturing facilities—first numeric PFAS effluent limits. 2024: California AB 1817 textile PFAS ban takes effect for apparel and outdoor apparel. 2024: Colorado, Maryland, Minnesota PFAS cosmetics bans effective. 2024: EU REACH: ECHA RAC and SEAC opinions on universal PFAS restriction expected. 2024: Japan enhanced PFAS inspection program for food contact articles at import. 2024: NSF/ANSI 61 updated to require PFAS extraction testing for fluoropolymer-containing plumbing products.
2025–2026: Infrastructure and Implementation
April 2025: Public water systems complete initial PFAS monitoring under NPDWR—all systems >10,000 must sample; results trigger compliance determinations. 2025: Systems exceeding MCLs must notify the public and begin implementing compliance plans. 2025: California AB 1817 textile PFAS ban expands to all textile articles. 2025: Minnesota omnibus PFAS products law effective for multiple product categories including food service products and juvenile products. 2025: NFPA 1971 PFAS-free turnout gear requirement for new structural firefighting gear purchases. 2025: FAA airport AFFF phase-out deadline for grant-funded facilities. 2026: EU REACH universal PFAS restriction expected to enter into force (Commission formal adoption pending ECHA opinions). 2026: DoD military PFAS procurement prohibition for AFFF (extended deadline). 2026: EU Drinking Water Directive PFAS limits transposition deadline for member states. 2026: WHO GDWQ PFAS guideline revision publication expected.
2027–2029: Treatment Infrastructure Completion
2027: EU REACH restriction derogation periods for specific sectors begin expiring; non-essential PFAS uses must cease. 2028: EPA NPDWR compliance deadline—all public water systems serving ≥25 people must be in compliance with PFAS MCLs by this date (systems that detected PFAS above MCLs must have treatment operational). 2028: California AB 1817 textile PFAS ban reaches full coverage (all textile articles). 2028: EPA aquatic life criteria for PFAS expected to be finalized—affecting NPDES permits for surface water dischargers. 2029: NPDWR compliance deadline for capital-intensive treatment infrastructure—utilities that require construction of new treatment facilities have until 2029 to complete installation. 2029: EPA expected to finalize additional PFAS MCLs for PFAS compounds beyond the initial 6—potentially covering PFBS, PFBA, and other short-chain compounds under UCMR 5 monitoring data.
Anticipated Future Actions (2030+)
Beyond the compliance calendar: EPA PFAS Strategic Roadmap commits to additional regulatory actions for PFAS in surface water, soil, air, and consumer products. EPA TSCA PFAS reporting rule creates ongoing disclosure requirements. Anticipated future EPA actions include: CERCLA designation of additional PFAS beyond PFOA and PFOS (PFBS, PFNA, GenX are candidates); ELGs for additional industrial categories using PFAS; maximum contaminant level goals (MCLGs) for additional PFAS; ambient water quality criteria for PFAS in surface water; and potential soil screening levels for PFAS at CERCLA sites. The EU’s universal restriction will be followed by sector-specific derogation expiration reviews and anticipated further restriction tightening as alternatives become available and monitoring demonstrates ongoing environmental burden from remaining uses.
The PFAS regulatory calendar through 2029 is the most consequential environmental compliance schedule in a generation—with multiple simultaneous deadlines creating an implementation race that requires immediate planning, funding applications, and treatment technology procurement to meet compliance timelines.
