EPA announced it will move forward with TSCA section 6(a) risk management to regulate 15 industrial and commercial conditions of use of 1,2-dichloroethane (1,2‑DCA), based on EPA’s final risk evaluation finding unreasonable risk to workers in 15 of 20 conditions of use (driven by inhalation and dermal exposure). EPA stated it did not identify unreasonable risk to consumers, the general population (including fish-consuming/Tribal communities), or the environment under evaluated conditions of use. Compliance teams should anticipate forthcoming workplace-focused restrictions/controls for affected 1,2‑DCA uses and monitor the referenced docket activity for proposed requirements, timelines, and any exemptions.
EPA published a rolling public list of TSCA Confidential Business Information (CBI) claims scheduled to expire (including claims expiring between June 22, 2026 and July 31, 2026) and stated it will refresh the list monthly. EPA also described a new electronic extension-request process in EPA’s Central Data Exchange (CDX) using a dedicated tool (TSCA Section 14(e) CBI Claim Extension Request). Companies must submit extension requests with substantiation no later than 30 days before claim expiration to maintain confidentiality protections; otherwise, EPA may no longer be required to protect the information from disclosure. Compliance teams should inventory TSCA submissions with CBI claims, monitor the monthly expiring-claims list, and prepare CDX extension filings within EPA’s stated timing window.
EPA announced a final rule on May 22, 2026 extending the TSCA Section 8(d) Health and Safety Data reporting deadline to May 21, 2027 for all 16 chemicals covered under the rule. Manufacturers (including importers) of these 16 chemicals must report data from unpublished health and safety studies to EPA by the new deadline.
EPA announced a proposed rulemaking to extend certain compliance dates in the final TSCA §6 risk management rules for perchloroethylene (PCE) and carbon tetrachloride (CTC). EPA stated existing compliance dates remain in effect unless and until revised through rulemaking, but EPA intends to focus compliance/enforcement resources on the new compliance dates that would be established if the proposal is finalized. Compliance teams using or supplying PCE/CTC should track the proposal and be prepared to re-baseline internal Workplace Chemical Protection Program timelines and related operational controls once new dates are finalized.
EPA published draft TSCA risk evaluation materials: draft risk evaluations for HHCB and phthalic anhydride and draft hazard assessments/supporting documents for o-dichlorobenzene and p-dichlorobenzene. EPA also announced Science Advisory Committee on Chemicals (SACC) peer review meetings (including a preparatory meeting) as part of the TSCA risk evaluation process. Compliance teams should review the drafts, consider submitting comments to the peer review docket, and assess whether conditions of use identified as presenting unreasonable risk could lead to future TSCA §6 risk management requirements if finalized.
EPA extended the public comment period for the proposed TSCA Section 5 Significant New Use Rules (SNURs) titled “Significant New Use Rules on Certain Chemical Substances (26-2).” The comment deadline is extended to July 10, 2026. This affects stakeholders planning to submit comments on the proposed SNURs and provides additional time to evaluate potential impacts on manufacturing (including import) or processing of substances subject to TSCA orders and SNUR-based notice requirements (SNUNs) prior to designated significant new uses.
EPA published a proposed rule to establish Significant New Use Rules (SNURs) for certain chemical substances (SNUR batch 26-2). If finalized, manufacturers and processors would be required to submit a Significant New Use Notice (SNUN) at least 90 days before commencing any activity designated as a significant new use (generally, activities not consistent with protective measures in underlying TSCA §5 orders). Compliance teams should determine whether any portfolio substances or planned uses could be affected and consider submitting comments by the stated deadline.
EPA published final Significant New Use Rules (SNURs) under TSCA Section 5 for a set of chemical substances (SNUR batch “26-2”). Companies that manufacture, import, or process any of the covered substances must evaluate whether their activities constitute a “significant new use” and, if so, submit a Significant New Use Notice (SNUN) before commencing that use. Compliance teams should identify whether any covered substances appear in products, intermediates, or R&D pipelines and update new-chemical/SNUR screening processes accordingly.
EPA issued a proposed rule to add Significant New Use Rules (SNURs) for certain chemical substances subject to TSCA consent orders. The proposal would require companies to submit a Significant New Use Notice (SNUN) at least 90 days before manufacturing or processing for a designated significant new use. Compliance teams should identify whether any affected substances are in their portfolios and consider commenting by the deadline; if finalized, SNUN planning/lead times and use restrictions may affect R&D, scale-up, importing, and downstream customer applications.
EPA announced a proposal to extend certain compliance dates in the final TSCA Section 6 risk management rules for perchloroethylene (PCE) and carbon tetrachloride (CTC) while EPA works to revise these rules. Compliance teams should note EPA’s statement that existing deadlines remain in effect unless/until changed through rulemaking; organizations subject to the PCE/CTC prohibitions and related downstream requirements should monitor the forthcoming Federal Register publication and comment period details referenced by EPA and prepare for potential updated phase-in timelines if the proposal is finalized.
EPA finalized a change to the TSCA Section 8(a)(7) one-time PFAS reporting timeline by moving the start of the reporting submission period from a fixed date (previously April 13, 2026) to a trigger date: 60 days after the effective date of EPA’s forthcoming revision to the PFAS 8(a)(7) rule. This impacts entities that manufactured or imported PFAS (including PFAS in articles) during the covered period and need to plan reporting readiness around a rule-triggered start rather than a calendar date.
EPA finalized a rule modifying the start of the submission period for TSCA §8(a)(7) PFAS reporting (40 CFR part 705). The submission period will begin on January 31, 2027, or 60 days after the effective date of a forthcoming final rule that will make substantive revisions to the PFAS reporting rule—whichever is earlier. This changes the prior planned April 13, 2026 start and affects entities that manufactured or imported PFAS during the covered lookback period by shifting compliance planning to the new trigger/backstop dates and requiring monitoring of the forthcoming final revision that starts the 60-day clock.
EPA published draft TSCA risk evaluation documents for HHCB and phthalic anhydride and draft hazard assessment/supporting materials for o-dichlorobenzene and p-dichlorobenzene, and announced a Science Advisory Committee on Chemicals (SACC) peer review meeting scheduled for June 8–12, 2026 (with a preparatory meeting on May 26, 2026). EPA highlighted that the draft risk evaluation for phthalic anhydride identifies unreasonable risks for certain worker and consumer exposures, which could drive later TSCA Section 6 risk management if finalized. Compliance teams should review draft findings, prepare public comments for the peer review docket, and anticipate potential downstream risk management actions for affected conditions of use.
EPA released draft TSCA risk evaluation and/or hazard assessment materials for HHCB, phthalic anhydride, o-dichlorobenzene (o-DCB), and p-dichlorobenzene (p-DCB), and announced TSCA Science Advisory Committee on Chemicals (SACC) peer review meeting dates (including a preparatory meeting on May 26, 2026 and a peer review meeting on June 8–12, 2026). Stakeholders should review the drafts and participate in the SACC/public docket process because draft conclusions (e.g., preliminary unreasonable-risk findings for certain chemicals/uses described by EPA) may inform subsequent TSCA Section 6 risk management actions.
EPA released draft TSCA risk evaluation and hazard assessment materials for four chemicals (HHCB, phthalic anhydride, o-dichlorobenzene, and p-dichlorobenzene) and announced the Science Advisory Committee on Chemicals (SACC) peer review process, which includes opportunities for public input. While drafts are not binding final determinations, they can materially influence final risk evaluations and potential downstream TSCA §6 risk management actions; compliance teams should review draft findings relevant to their uses and consider participating in the peer review/comment process.
EPA finalized a change to the start of the submission period for the TSCA §8(a)(7) PFAS Reporting and Recordkeeping Rule (40 CFR Part 705). Instead of a fixed start date, the submission period will begin 60 days after the effective date of a forthcoming final rule that revises the substantive requirements, or on January 31, 2027, whichever is earlier. This directly affects compliance planning, internal calendars, and resourcing for entities that manufactured (including imported) PFAS during the covered period.
EPA finalized an update to the TSCA Section 8(a)(7) one-time PFAS reporting rule changing when the submission period starts. Instead of beginning April 13, 2026, the start is moved to a date tied to a forthcoming final rule revising the PFAS reporting regulation (start is triggered 60 days after that revision’s effective date). This affects compliance planning for entities that manufactured (including imported) PFAS during 2011–2022, including preparation of data systems, supplier outreach, and internal record collection timelines.
EPA announced/finalized a change to the start of the TSCA §8(a)(7) PFAS one-time reporting submission period. The prior start date of April 13, 2026 is replaced with a trigger tied to a forthcoming final rule revising the PFAS §8(a)(7) rule: the submission period will begin 60 days following the effective date of that forthcoming final rule, with a backstop start date of January 31, 2027 (whichever is earlier). Compliance teams responsible for TSCA PFAS reporting (entities that manufactured, including imported, PFAS during 2011–2022) should adjust project timelines to the new trigger while continuing data gathering because the underlying reporting obligation remains.
EPA finalized a change to the TSCA §8(a)(7) PFAS reporting timeline: the start of the submission period is no longer a fixed April 13, 2026 date. Instead, the reporting window will begin 60 days after the effective date of a forthcoming final rule revising the PFAS reporting regulation, with a backstop start date of January 31, 2027 (whichever is earlier, as described in the signed pre-publication final rule). This affects entities that manufactured (including imported) PFAS during the 2011–2022 lookback period (including certain article importers), requiring compliance teams to re-baseline project plans for data collection, supplier outreach, and internal system readiness against the new trigger-based start date.
EPA announced/finalized a change to the start of the submission period for the TSCA Section 8(a)(7) one-time PFAS reporting rule. The update moves the start of the reporting period from April 13, 2026 to 60 days after the effective date of a forthcoming final rule revising the TSCA PFAS reporting rule (scope revisions). This affects entities that manufactured (including imported) PFAS during 2011–2022 and changes internal compliance project timelines (data collection, supplier outreach, and submission readiness).
