EPA issued a proposed rule to amend the TSCA §8(a)(7) one-time PFAS reporting and recordkeeping requirements for PFAS manufactured/imported during 2011–2022. The proposal would add/clarify multiple exemptions (including an exemption for imported articles and exemptions for certain byproducts, impurities, R&D chemicals, and non-isolated intermediates) and introduce a de minimis threshold (PFAS in mixtures/products at ≤0.1%) along with other technical corrections and adjustments to reporting mechanics. EPA indicated the proposal would be open for comment (e.g., 45 days after Federal Register publication, as described in the prepublication materials). Compliance teams should assess whether operations and supply chains qualify for proposed exemptions and prepare comments/positioning given potential scope reductions and reporting burden changes.
EPA finalized an extension of certain compliance dates in the TSCA §6 methylene chloride risk management rule for non-federal industrial/commercial laboratories, including Workplace Chemical Protection Program (WCPP) elements (e.g., monitoring, regulated areas/ECEL compliance, and related plans/controls) and associated recordkeeping. This changes when covered laboratories must meet specific WCPP obligations, affecting internal implementation timelines, SOP updates, and contractor/lab compliance planning.
EPA signed a final rule (pre-publication copy) extending certain Workplace Chemical Protection Program (WCPP) and related recordkeeping compliance dates for industrial/commercial laboratories that are not federally owned/operated under the TSCA section 6 methylene chloride rule. The research summary lists specific date extensions for initial monitoring, regulated areas/ECEL compliance, and exposure controls/exposure control plan milestones. Compliance teams at affected laboratories should update implementation plans, monitoring schedules, and documentation systems to align with the extended deadlines.
EPA issued a final rule (pre-publication copy signed Nov. 7, 2025) extending certain compliance dates for the methylene chloride TSCA Section 6 risk management rule as it applies to industrial/commercial laboratories (non-federal). The pre-publication notice describes an 18-month extension for multiple Workplace Chemical Protection Program (WCPP) and recordkeeping deadlines (e.g., initial monitoring, regulated areas/ECEL compliance, exposure limits methods/exposure control plan). Compliance teams in labs using methylene chloride should update implementation plans, internal deadlines, and contractor/worker protection procedures to reflect the extended dates once confirmed in the Federal Register publication.
EPA’s New Chemicals Program updates reflect multiple Significant New Use Rule (SNUR) actions under TSCA Section 5 affecting substances that were subject to PMNs/TSCA orders. EPA published a final SNUR batch (“24-4.5e”) in the Federal Register on Nov. 4, 2025, with an effective date of Jan. 5, 2026, creating Significant New Use Notice (SNUN) notification triggers for the covered substances/uses. EPA also published several proposed SNUR batches (Nov. 3, 2025) and proposed amendments to existing SNURs (Oct. 28, 2025), each with associated public comment periods via Regulations.gov dockets. Compliance teams should review whether any substances in their portfolios are covered by the final SNUR effective Jan. 5, 2026 and monitor/participate in proposed SNUR actions that could add or modify SNUN obligations.
EPA finalized a batch of Significant New Use Rules (SNURs) under TSCA Section 5, establishing significant new uses that trigger Significant New Use Notice (SNUN) obligations before manufacture, import, or processing for those uses can begin. This is a binding regulatory change for entities handling covered substances, requiring screening of uses against the SNUR conditions and updating internal new-use change-management to ensure SNUN submissions occur before initiating any designated significant new use. The research notes the final SNUR batch was published Nov. 4, 2025 and became effective Jan. 5, 2026.
EPA published final significant new use rules (SNURs) for chemical substances that were the subject of premanufacture notices (PMNs), TSCA Orders, and proposed rules (Batch '24-4.5e'). The SNURs require anyone intending to use the chemicals under certain conditions to notify EPA at least 90 days before beginning that use, allowing EPA to evaluate potential risks from the new use. Published in the Federal Register (90 FR 14743).
EPA finalized a set of Significant New Use Rules (SNURs) (batch 24-4.5e) covering certain chemical substances/new uses. SNURs require submitters to file a Significant New Use Notice (SNUN) before engaging in designated significant new uses, affecting manufacturing/import and downstream use planning. Compliance teams should identify whether any substances in their portfolios fall within the batch and ensure SNUN and supply-chain communication processes are in place before any covered new uses occur.
EPA proposed multiple SNUR batches (published Nov. 3, 2025) and proposed amendments to existing SNURs (published Oct. 28, 2025). If finalized, these proposals would impose or modify TSCA Section 5 Significant New Use Notice (SNUN) requirements for specified chemical substances/uses. Compliance teams should monitor the relevant dockets, evaluate whether their substances/uses could be affected, and consider submitting comments as appropriate.
EPA proposed several batches of Significant New Use Rules (SNURs) (24-5.5e, 25-1.5e, 25-2.5e). If finalized, these SNURs would require submission of a SNUN before certain new uses can proceed. Stakeholders had an opportunity to comment (deadline stated as Dec. 3, 2025) and should track finalization outcomes for implications on commercialization, import, and downstream use conditions.
EPA proposed amendments/modifications to existing SNUR requirements (batch 23-1.M). The proposal would adjust significant new use designations for covered substances and opened a public comment period (deadline stated as Nov. 28, 2025). Companies should review whether amended SNUR triggers could affect current or planned uses and consider submitting comments and preparing for potential final changes.
EPA announced it will prioritize review of new chemicals under TSCA that are intended for use in data center projects or for manufacturing of covered components, as defined by Executive Order 14318. The prioritization applies to submissions received on or after September 29, 2025. This policy change aims to support American manufacturing and technological advancement by expediting reviews for data center-related chemicals.
EPA proposed amendments to the TSCA risk evaluation procedures rule (the ‘Framework Rule’) that governs how EPA conducts existing-chemical risk evaluations. The proposal (per EPA’s release) would adjust key procedural elements such as conditions-of-use determinations and other evaluation process components, and opens a public comment period. Compliance teams should assess how the proposed procedural changes could affect the scope, pace, and content of future TSCA risk evaluations relevant to their chemical portfolios and consider submitting comments.
EPA proposed changes to the 2024 Risk Evaluation rule that would ensure EPA can more efficiently and effectively protect human health and the environment while responding to public comments and concerns from other Federal agencies. The proposed amendments address the Framework Rule governing how EPA conducts risk evaluations for existing chemical substances under TSCA Section 6.
EPA issued a proposed rule to amend procedures for conducting chemical risk evaluations for existing chemicals under TSCA. This proposal would revise the risk evaluation framework and could affect how companies plan for risk evaluation scope, data submissions, use categorization, and downstream risk management implications. Compliance teams should review the proposal and consider participating in the public comment process for impacts to ongoing and future TSCA risk evaluations.
EPA announced a proposed rule to revise the procedures for conducting TSCA risk evaluations for existing chemicals (the TSCA risk evaluation framework/procedural rule). The proposal describes changes affecting how EPA makes risk determinations (including around conditions of use and exposure pathways), treatment of occupational exposure controls (e.g., PPE/engineering controls), and related procedural/definition updates. Companies with substances undergoing TSCA risk evaluation should assess potential impacts on evaluation scope and assumptions and consider submitting comments in the associated docket once the proposal is published in the Federal Register.
EPA announced a proposed rule to revise the process/procedures for conducting TSCA risk evaluations for chemicals already in commerce (existing chemicals), intended to increase efficiency and better protect health and the environment. The proposal opens a public comment period (duration described by EPA in the news release). Compliance teams should assess how potential changes could affect scope, pace, and data expectations for TSCA risk evaluations, and consider submitting comments via the associated docket if affected.
EPA has issued a final rule extending compliance dates for the Trichloroethylene (TCE) risk management regulation under TSCA. This action provides additional time for regulated entities to meet compliance obligations under the TSCA risk management requirements for TCE.
EPA announced a policy to prioritize review of new chemicals used in data center projects under TSCA. This prioritization supports American manufacturing and technological advancement by accelerating TSCA review timelines for chemicals essential to data center operations.
EPA released the latest biannual update to the TSCA Inventory on August 14, 2025. The TSCA Inventory is a comprehensive list of all existing chemical substances manufactured, processed, or imported in the U.S. under TSCA. The public portion is available on EPA's website, while substances claimed as Confidential Business Information require valid bona fide intent to access. This update helps companies determine whether substances are 'new' (requiring PMN) or 'existing' (on the inventory).
