The statement confirms Illinois Community Water Supplies must complete initial monitoring by April 25, 2027, begin ongoing compliance monitoring on April 26, 2027, and achieve MCL compliance by April 26, 2029.
Secretariat letter MC/COP6/2026/32 communicates COP-7 timeline and multiple submission windows (including Article 6(6) exemption-extension request timing)
The Secretariat issued letter MC/COP6/2026/32 summarizing key dates related to COP-7 (including meeting dates) and highlighting timelines for Party actions/submissions. The letter flags that Parties intending to request an exemption extension under Article 6(6) should submit requests preferably by 6 March 2027 and no later than 6 July 2027, and it also lists several nearer-term submission/comment deadlines for COP-7 preparatory work (e.g., effectiveness evaluation scientific report comments; inputs on mercury-added cosmetics implementation challenges; inputs on financial mechanism experiences). Compliance and policy teams supporting Party submissions or tracking likely future controls should calendar these dates.
EPA proposes rescinding NPDWR determinations/requirements for PFHxS, PFNA, HFPO‑DA (GenX) and Hazard Index mixture provisions
EPA issued a proposed rule to rescind the Safe Drinking Water Act (SDWA) regulatory determinations and remove related provisions in the 2024 PFAS NPDWR for PFHxS, PFNA, HFPO‑DA (GenX chemicals), and Hazard Index mixture-related provisions (mixtures including PFBS alongside PFHxS/PFNA/HFPO‑DA). Compliance teams for drinking-water utilities, primacy agencies, and downstream stakeholders should track the proposal, assess potential changes to monitoring/compliance programs for the affected PFAS/Hazard Index components, and consider submitting comments during the public comment period once published in the Federal Register.
EPA proposes federal exemption framework extending PFOA/PFOS MCL compliance deadline from April 26, 2029 to April 26, 2031
EPA proposed a rule (signed May 18, 2026 per EPA materials) to keep the PFOA and PFOS MCLs while creating a federal exemption mechanism that would allow eligible water systems additional time to comply—extending the compliance deadline from April 26, 2029 to April 26, 2031. Compliance teams should evaluate eligibility criteria described by EPA, prepare for the public comment/hearing process, and reassess implementation project timelines and interim mitigation expectations during any exemption period.
EPA announces it will keep PFOA/PFOS MCLs while pursuing compliance deadline extension and reconsidering other PFAS components
EPA issued an official announcement summarizing its planned approach for the PFAS NPDWR: retain the PFOA and PFOS maximum contaminant levels (MCLs) while advancing proposed rulemaking actions that would extend the compliance timeline and separately reconsider/rescind certain other PFAS components (PFHxS, PFNA, HFPO‑DA/GenX and Hazard Index mixture provisions). This is not itself a binding rule change, but it is an authoritative compliance-signaling update confirming EPA’s intended direction and linking stakeholders to the relevant proposed actions and timelines.
EPA proposed rescinding 2024 NPDWR provisions for PFHxS, PFNA, HFPO‑DA (GenX) and Hazard Index mixtures (incl. PFBS)

EPA issued a proposed rule under the Safe Drinking Water Act to rescind the regulatory determinations and remove related regulatory provisions for PFHxS, PFNA, HFPO‑DA (GenX), and the Hazard Index mixture approach (including PFBS). If finalized, the proposal would remove the MCLGs/MCLs and associated monitoring/treatment/reporting requirements in 40 CFR Parts 141 and 142 that apply exclusively to those PFAS determinations, while leaving PFOA and PFOS MCLGs/MCLs unchanged. Compliance teams supporting drinking-water utilities and related supply chains should assess impacts to PFAS monitoring, treatment planning, primacy implementation activities, and customer communication, and consider participating in the comment process.
EPA proposes federal exemption framework extending PFOA/PFOS MCL compliance deadline to April 26, 2031; hearing scheduled
EPA issued a proposed rule that would retain the PFOA and PFOS drinking water maximum contaminant levels (MCLs) but create a federal exemption framework allowing eligible water systems to request two additional years to comply—extending the compliance date to April 26, 2031 (from April 26, 2029). The proposal provides for a written comment period (stated as 60 days after Federal Register publication) and schedules a virtual public hearing for July 7, 2026 (with pre-registration noted as July 1, 2026 on the EPA materials). Compliance teams at water utilities should evaluate eligibility/criteria implications and adjust PFAS NPDWR implementation schedules and capital planning assumptions pending finalization.
EPA proposed federal exemption framework to extend PFOA/PFOS MCL compliance deadline to April 26, 2031
EPA proposed a rule that would create a federal exemption framework allowing eligible public water systems additional time to comply with the PFOA and PFOS maximum contaminant levels (MCLs), extending the compliance deadline to April 26, 2031 for approved systems. This is a significant timeline/implementation change for utilities planning treatment upgrades and capital projects. The proposal is accompanied by EPA supporting materials (pre-publication FR notice and FAQs) and uses a formal rulemaking docket process.
EPA proposes rescinding SDWA regulatory determinations and removing NPDWR provisions for PFHxS, PFNA, HFPO‑DA (GenX) and Hazard Index mixture (incl. PFBS)
EPA released a proposed rule to rescind the Safe Drinking Water Act regulatory determinations and remove associated National Primary Drinking Water Regulation (NPDWR) provisions for PFHxS, PFNA, HFPO‑DA (GenX), and the Hazard Index mixture (PFHxS + PFNA + HFPO‑DA + PFBS). If finalized, this would eliminate the monitoring/compliance obligations tied specifically to these contaminants under the 2024 PFAS drinking water rule, while (per EPA) not affecting PFOA/PFOS provisions. EPA indicates a 60‑day public comment period will run after Federal Register publication and the agency has scheduled a virtual public hearing for July 7, 2026 (registration details on EPA’s page).
