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 issued a proposed rule to rescind the SDWA regulatory determinations and remove associated 2024 PFAS NPDWR provisions covering PFHxS, PFNA, HFPO‑DA (GenX), and Hazard Index mixtures that include PFBS. The proposal initiates a public comment process (60 days after Federal Register publication per EPA materials) and includes a scheduled virtual public hearing on July 7, 2026 with preregistration by July 1, 2026. Compliance teams at public water systems and supporting consultants should track this rulemaking closely because, if finalized, it would roll back federal drinking-water standard provisions for these PFAS/mixture components, changing monitoring/treatment/planning assumptions under the 2024 NPDWR framework.
EPA published a proposed rule under the Safe Drinking Water Act to rescind regulatory determinations and remove related provisions of the 2024 PFAS NPDWR for PFHxS, PFNA, HFPO‑DA (GenX), and Hazard Index mixtures (PFHxS + PFNA + HFPO‑DA + PFBS). EPA indicates the proposal would not affect the PFOA/PFOS portions of the NPDWR. EPA states there will be a 60-day written comment period after Federal Register publication and a virtual public hearing scheduled for July 7, 2026 (with pre-registration by July 1, 2026). Compliance teams at drinking water systems and supporting suppliers/consultants should track this rulemaking because it could remove monitoring/treatment/compliance obligations for these PFAS constituents if finalized.
EPA issued a proposed rule to retain the PFOA and PFOS maximum contaminant levels (MCLs) while creating a federal exemption framework under SDWA that would allow eligible public water systems additional time to comply—extending the compliance deadline from April 26, 2029 to April 26, 2031 for systems that request the exemption. Compliance teams at public water systems and primacy agencies should evaluate eligibility criteria and documentation needs, update project timelines and capital planning assumptions, and consider participating in the public comment process.
EPA issued a proposed rule to rescind Safe Drinking Water Act regulatory determinations and remove associated provisions in the 2024 PFAS NPDWR that are exclusive to PFHxS, PFNA, HFPO‑DA (GenX chemicals), and the Hazard Index mixture approach (mixtures including these PFAS plus PFBS). If finalized, this would change the scope of federally regulated PFAS drinking-water requirements by removing/altering monitoring/treatment/other NPDWR obligations tied to these specific PFAS/HI components (while leaving PFOA/PFOS requirements outside the scope of this proposal). EPA opened a written public comment process (60-day comment period after Federal Register publication) and scheduled a virtual public hearing for July 7, 2026 (speaker pre-registration deadline July 1, 2026; docket EPA-HQ-OW-2025-0654).
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 (via its PFAS drinking-water page and related news release) summarized that it issued two proposed SDWA actions concerning the 2024 PFAS National Primary Drinking Water Regulation (NPDWR): (1) a proposed approach to allow an opt-in compliance extension for PFOA/PFOS maximum contaminant levels (MCLs) via an exemption framework; and (2) a proposed rescission of certain other PFAS NPDWR components (PFHxS, PFNA, HFPO-DA/GenX, and the Hazard Index mixture approach including PFBS). This item is a communications/guidance-style announcement (not the Federal Register proposal itself) and can be used by compliance teams to track EPA’s stated direction and link stakeholders to the underlying proposed rule pages/dockets.
EPA issued a proposed rule under the Safe Drinking Water Act to rescind the regulatory determinations and remove related provisions from the 2024 PFAS drinking water regulation for PFHxS, PFNA, HFPO‑DA (GenX), and the Hazard Index mixture of these PFAS (including PFBS). EPA set a public comment deadline and scheduled a public hearing with preregistration, creating near-term stakeholder action items for water systems, states/primacy agencies, and impacted entities tracking NPDWR scope changes.
EPA posted a proposed rule to rescind SDWA regulatory determinations and associated provisions of the 2024 PFAS National Primary Drinking Water Regulation (NPDWR) that apply to PFHxS, PFNA, HFPO‑DA (GenX), and the Hazard Index mixture (PFHxS, PFNA, HFPO‑DA plus PFBS). If finalized, this would remove the MCLs/MCLGs and related monitoring/treatment obligations that are specific to these PFAS/mixture, while leaving PFOA and PFOS provisions intact. Compliance teams supporting water utilities, product stewardship, and risk communication should monitor the docket and comment/hearing process because it could materially change monitoring and treatment programs built around these four components.
EPA published an updated interim guidance document on the destruction and disposal of PFAS and PFAS-containing materials. The update outlines disposal/destruction pathways EPA characterizes as having lower potential for PFAS release (e.g., certain underground injection control wells, hazardous waste landfills, and hazardous waste combustors under specified conditions) and signals EPA’s current recommended practices for waste management and remediation decision-making. EPA also opened a public comment opportunity, stating it will accept comments for 60 days following Federal Register publication. Compliance teams managing PFAS wastes (manufacturers, waste handlers, remediation project managers) should review the revised recommendations and track the associated docket/comment timeline.
EPA published an updated 2026 version of its Interim Guidance on the destruction and disposal of PFAS and PFAS-containing materials. While non-binding, the guidance is a key compliance reference for organizations managing PFAS wastes/materials (e.g., AFFF, contaminated media, and water-treatment residuals) and discusses available destruction/disposal pathways and evaluation considerations. EPA indicates it will accept comments on the interim guidance (public-comment posture).
EPA published an updated 2026 version of its interim guidance addressing destruction and disposal of PFAS and PFAS-containing materials. The guidance discusses considerations for large-scale management pathways (e.g., thermal treatment, landfills, underground injection) and provides an evaluation framework and discussion of uncertainties/data gaps. While non-binding, this guidance is widely used to inform PFAS waste management decisions and may influence acceptable practices in permitting, procurement specifications, and contractor selection for PFAS-containing waste streams.
EPA issued the “Interim Guidance on the Destruction and Disposal of PFAS and Materials Containing PFAS—2026 Version,” updating EPA’s recommended approaches and discussion of disposal/destruction pathways (including thermal treatment, landfills, and underground injection) and adding/expanding a framework for evaluating emerging technologies. EPA also indicates a 60-day public comment period will be available via the associated regulations.gov docket following Federal Register publication. While non-binding, this guidance can influence waste vendor qualification, internal waste acceptance/testing protocols, and defensible management practices for PFAS-containing waste streams.
EPA released the 2026 version of its Interim Guidance on the Destruction and Disposal of PFAS and materials containing PFAS. While non-binding, the guidance can influence cleanup decisions, permitting expectations, and selection of waste management technologies (e.g., thermal treatment, landfilling, underground injection) by providing EPA’s current assessment of available information and uncertainties. Compliance teams managing PFAS wastes should review the updated recommendations and align internal waste handling/disposal evaluations and contractor specifications accordingly.
EPA published the 2026 version of its Interim Guidance on the Destruction and Disposal of PFAS and Materials Containing PFAS. The guidance updates EPA’s information and evaluation considerations for PFAS destruction/disposal pathways (e.g., thermal treatment, landfill disposal, underground injection) and includes an updated framework for assessing and selecting technologies. While non-binding, it is a key reference used by regulated parties and decision-makers managing PFAS-containing wastes and remediation residuals.
EPA released an updated 2026 version of its Interim Guidance on destruction and disposal of PFAS and PFAS-containing materials. While non-binding, it is compliance-relevant for organizations managing PFAS wastes (e.g., spent media, AFFF wastes, contaminated soils/biosolids) because it consolidates EPA’s current recommendations and risk considerations for destruction/disposal pathways (e.g., thermal treatment, landfilling, underground injection) and provides an evaluation framework for emerging technologies. Compliance teams should review vendor/technology selection, waste profiles, and permitting/records narratives against the updated guidance and any associated public-comment process referenced in the guidance materials.
EPA issued the 2026 version of its Interim Guidance on the destruction and disposal of PFAS and PFAS-containing materials (not a binding rule, but influential for PFAS waste management decisions). The guidance discusses considerations and limitations for common management technologies (e.g., thermal treatment, landfilling, underground injection) and includes an evaluation framework for emerging technologies. EPA also opened a public comment opportunity tied to this interim guidance, which compliance and EHS teams should monitor when selecting or validating PFAS waste treatment/disposal pathways and documenting technology decisions.
EPA announced the launch of the PFAS OUTreach (PFAS OUT) initiative to proactively work with drinking water systems to reduce exposure to PFOA and PFOS ahead of federal compliance timelines. While not a new binding requirement, this is an implementation-support and compliance-readiness signal that may affect expectations for utilities’ planning, monitoring, and risk-reduction actions under SDWA PFAS standards.
ECHA’s Registry of restriction intentions indicates the EU-wide PFAS restriction dossier (REACH restriction process) remains in “opinion development,” with a latest update shown as 16 April 2026. This is not a final restriction, but it is an official process/status update that compliance teams can use to monitor progress toward RAC/SEAC opinions and subsequent European Commission decision-making, and to plan engagement for any upcoming consultations and evidence submission needs (uses, alternatives, socio-economic impacts).
EPA announced the launch of its PFAS OUT (PFAS OUTreach) initiative to provide assistance/outreach intended to help drinking water systems proactively address PFAS contamination and support implementation planning for federal PFAS drinking water requirements. For compliance teams at public water systems and supporting contractors, this signals increased federal engagement and availability of implementation resources (e.g., technical assistance, planning support) but does not itself create new binding limits.
