EPA completed the final risk evaluation for 1,3-Butadiene (CAS 106-99-0) under TSCA in December 2025. The risk evaluation determines whether the chemical presents unreasonable risk to health or the environment under its conditions of use, which will inform potential risk management actions under TSCA Section 6.
EPA released an updated draft risk calculation memorandum and supporting documents for formaldehyde under TSCA and opened a 60-day public comment period (stated to run until February 2, 2026) via the TSCA docket on Regulations.gov. Compliance teams following TSCA risk evaluation work should review the draft methodology/assumptions and consider submitting comments, as approaches in the memorandum can influence downstream TSCA risk evaluation conclusions and potential risk management actions.
EPA released an updated draft Risk Calculation Memorandum for formaldehyde under TSCA and opened a 60-day public comment period (noted as open until February 2, 2026). This is a technical support/analytical document that can influence how EPA quantifies and characterizes risk in the formaldehyde TSCA risk evaluation, which in turn can affect downstream risk management decisions and stakeholder engagement strategies. Compliance teams should review the draft methodology and submit comments if assumptions, exposure parameters, or calculation approaches affect their uses or conditions of use.
EPA posted an update stating it intends to reconsider the December 13, 2024 final TSCA Section 8(d) rule requiring manufacturers/importers of 16 chemicals to submit unpublished health and safety studies. EPA indicates reconsideration topics may include additional exemptions, a reporting threshold, and changes to the lookback period, and notes it anticipates appropriate action regarding the reporting deadline currently identified as May 22, 2026. Compliance teams subject to the 8(d) rule should monitor for subsequent rulemaking that could alter applicability or timing and should plan around the currently stated deadline until changes are finalized.
EPA published the key default values used in its risk assessments for new chemicals (TSCA section 5 reviews). This transparency update can affect how submitters and compliance teams prepare PMNs, exemption submissions, and supporting exposure/hazard arguments because EPA’s default assumptions influence risk determinations and potential TSCA orders/SNUR conditions. Companies should align dossiers and internal modeling with EPA’s published defaults and document any proposed alternative values with supporting rationale.
EPA proposed revisions to the TSCA Section 8(a)(7) PFAS reporting and recordkeeping rule intended to reduce reporting burden by proposing changes to scope and exemptions (as described in EPA communications), including potential exclusions for certain PFAS in products/mixtures at low concentrations, certain imported articles, certain byproducts/impurities, R&D chemicals, and non-isolated intermediates. If finalized, these changes could materially alter who must report and what activities are reportable under 40 CFR Part 705; compliance teams should monitor the proposal and evaluate how potential exemptions would change reporting applicability and data-collection needs.
EPA’s status update page for the TSCA risk management rule for trichloroethylene (TCE) states EPA is further postponing the effective date of the TSCA §6(g) exemption requirements in the final TCE rule until Feb. 17, 2026 (as described on the EPA update page, in connection with ongoing litigation/court timing). Compliance teams affected by TCE restrictions should update internal implementation schedules and ensure exemption-related compliance activities align to the postponed effective date and any related EPA communications referenced on the landing/status pages.
EPA issued a final rule extending certain compliance dates under the TSCA Section 6 methylene chloride risk management rule for industrial/commercial laboratories that are not Federal. The extension (described in the research as 18 months) shifts key Workplace Chemical Protection Program (WCPP) and associated recordkeeping deadlines (e.g., initial monitoring, regulated areas/ECEL compliance, exposure control plan and methods of compliance). Compliance teams in laboratory settings using methylene chloride should update project plans, industrial hygiene monitoring schedules, and written program deadlines to reflect the revised dates.
EPA proposed amendments to the TSCA Section 8(a)(7) PFAS reporting and recordkeeping requirements to reduce potentially duplicative reporting. The proposal includes exemptions/limitations such as PFAS in mixtures/products at ≤0.1%, imported articles, and certain byproducts, impurities, R&D substances, and non-isolated intermediates. If finalized, these changes would materially affect who must report and what information is required for the one-time PFAS reporting covering 2011–2022 manufacturing/import.
EPA issued a proposed rule to revise the TSCA §8(a)(7) PFAS reporting and recordkeeping requirements (40 CFR Part 705) to make reporting more practical/implementable. The proposal would introduce or clarify exemptions and reporting mechanics, including a proposed de minimis concept (PFAS in mixtures/products at ≤0.1% concentration), and proposed exemptions/adjustments affecting imported articles, certain byproducts, impurities, R&D, and non-isolated intermediates, alongside technical corrections and potential adjustments to the submission period. EPA indicated a public comment period of 45 days upon Federal Register publication. Compliance teams should assess whether their PFAS reporting population and data-collection scope would change if the proposal is finalized and consider submitting comments on feasibility and burden impacts.
EPA issued a proposal to revise the TSCA §8(a)(7) PFAS reporting and recordkeeping rule to make the requirements more practical/implementable. The proposal describes potential exemptions (e.g., certain impurities, byproducts, R&D, non-isolated intermediates, imported articles, and mixtures/products at or below a concentration threshold) and other changes such as technical corrections and adjustments to reporting mechanics/submission period. Compliance teams should review applicability and prepare to comment and/or reassess reporting scoping assumptions for 2011–2022 PFAS manufacturing/import activity.
EPA signed and announced a proposed rule to amend the TSCA §8(a)(7) PFAS data reporting and recordkeeping requirements (40 CFR Part 705). The proposal would add several exemptions (including imported articles and a de minimis 0.1% concept) and make other practical/technical changes intended to reduce burden while maintaining access to safety data. Compliance teams subject to PFAS reporting should assess whether their operations would fall in/out of scope if finalized and consider submitting comments through the rulemaking docket during the comment period described by EPA (stated as 45 days after Federal Register publication in the research text).
EPA issued a proposed rule (prepublication document signed Nov 10, 2025) to revise the TSCA §8(a)(7) PFAS data reporting and recordkeeping requirements (one-time reporting covering PFAS manufactured/imported during 2011–2022). The proposal would make reporting more practical by introducing/clarifying multiple exemptions and scope limitations (including imported articles and a de minimis threshold of ≤0.1% in mixtures/products, plus exemptions for certain byproducts, impurities, R&D, and non-isolated intermediates), along with technical corrections and adjustments to the submission period. EPA indicated a public comment period of 45 days upon Federal Register publication. Compliance teams should evaluate whether their PFAS-related activities could become exempt (e.g., article importers) and track the final rule and any changes to submission timing and data elements.
EPA issued a proposed rule to revise the TSCA §8(a)(7) PFAS one-time reporting and recordkeeping rule (40 CFR Part 705). The proposal would add/clarify exemptions (including a de minimis concept referenced in the research, and exemptions related to imported articles, byproducts, impurities, R&D, and non-isolated intermediates), make technical corrections, and adjust reporting mechanics/submission period. Compliance teams tracking PFAS data obligations should review applicability changes and prepare comments during the open comment period once published in the Federal Register.
EPA issued a proposed rule to revise the TSCA Section 8(a)(7) one-time PFAS reporting and recordkeeping requirements (covering PFAS manufactured/imported during 2011–2022) to make the program more practical/implementable. The proposal includes new/expanded exemptions and changes to reporting mechanics (e.g., potential exclusions for certain PFAS in products/mixtures at low concentration, imported articles, byproducts, impurities, R&D, and non-isolated intermediates, as described in the research summary) and would alter what information companies must submit and who must report. Compliance teams should evaluate whether their products/import streams could fall within proposed exemptions, prepare to submit comments within the comment period, and plan for potential scope changes that could reduce or reshape reporting obligations if finalized.
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 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 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 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 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.
