**SUPPLEMENTARY INFORMATION:**
**I. Executive Summary**
**A. Does this action apply to me?**
You may be potentially affected by this action if you manufacture (including import) any of the chemical substances listed in 40 CFR 716.120(d) of the regulatory text of this document. The following list of North American Industrial Classification System (NAICS) codes affected by this rule are those that align with these activities:
• Chemical manufacturers (including importers), (NAICS code 325); and
• Petroleum refineries (NAICS code 324110).
This action applies to manufacturers in these NAICS codes who are currently manufacturing (including importing) a listed chemical substance (or will do so during the chemical's reporting period) or who have manufactured (including imported) or proposed to manufacture (including import) a listed chemical substance within the last 10 years.
**B. What action is the Agency taking?**
EPA is proposing to extend the reporting deadline for the data submission period for the TSCA section 8(d) Health and Safety Data Reporting Rule.
**C. What is the Agency's authority for taking this action?**
The Health and Safety Data Reporting rule for the 16 chemical substances is promulgated under TSCA section 8(d) (15 U.S.C. 2607(d)) and codified at 40 CFR part 716. EPA's statutory authority to modify the deadline for the final TSCA section 8(d) rule is the same statutory authority relied upon to promulgate the underlying rule.
The statutory provision, along with administrative agencies' authority to reconsider prior regulations, provides EPA's authority for the targeted amendment to the compliance deadline finalized in this action. Unless provided otherwise by statute, an agency may change existing positions ( *e.g.,* reconsider, revise, or rescind prior rules) provided they acknowledge the change in position, offer a reasonable explanation for the change, and take any serious reliance interests into account. *See, e.g., FDA* v. *Wages & White Lion Invs., L.L.C.,* 145 S. Ct. 898, 917 (2025); *Encino Motorcars* v. *Navarro,* 579 U.S. 211, 221 (2016); *FCC* v. *Fox Television Stations, Inc.,* 556 U.S. 502, 515 (2009); *Motor Vehicle Mfrs. Ass'n* v. *State Farm Mut. Auto. Ins. Co.,* 463 U.S. 29 (1983).
**D. Why is the Agency taking this action?**
EPA promulgated a final rule on December 13, 2024 (89 FR 100756 (FRL-11164-02-OCSPP)), to require manufacturers (including importers) of 16 specific chemical substances to submit copies and lists of certain unpublished health and safety studies to the EPA. The 16 chemical substances were added to 40 CFR 716.120 to support ongoing and upcoming activities under TSCA section 6. On March 13, 2025, EPA extended the submission deadlines from March 13, 2025, to June 11, 2025, for vinyl chloride (CASRN 75-01-4) and from March 13, 2025, to September 9, 2025, for the remaining 15 chemical substances. *See* (90 FR 11899 (FRL-11164.-02-OCSPP). On June 9, 2025, EPA amended the submission deadlines for all 16 chemical substances subject to the rule to May 22, 2026. EPA now recognizes a need to further extend these reporting deadlines as noted below.
EPA is considering a proposal to modify the scope of the TSCA section 8(d) Health and Safety Data Reporting Rule. Such a rulemaking would make infeasible the current reporting deadline of May 22, 2026, (90 FR 24228 June 9, 2025 (FRL-11164.2-02-OCSPP)). EPA is proposing to extend the reporting deadline by one year to May 21, 2027. Should EPA finalize modifications to the TSCA section 8(d) Health and Safety Data Reporting Rule, the Agency's final action on the rule would update the deadline, as appropriate.
EPA is taking this action because it has determined additional time is necessary to alleviate the compliance burdens associated with this one-time reporting rule while EPA considers potential modifications to the regulations, including aligning the rule with Executive Order 14219 “Ensuring Lawful Governance and Implementing the President's `Department of Government Efficiency' Deregulatory Initiative” (90 FR 10583, February 19, 2025) and EPA's Powering the Great American Comeback Initiative Pillar I: Clean Air, Land, and Water for Every American. Rather than requiring businesses to prepare submissions under a rule that is in the process of being revised, this action provides regulatory certainty and prevents duplicative or potentially inconsistent reporting. Once the updated rule is finalized, reporting requirements and timelines will be clearly communicated to ensure a smooth and efficient compliance process. EPA is not reopening or reconsidering provisions of the underlying regulations other than the submission deadline in this rule.
**II. Request for Comment**
EPA invites comments on all aspects of this proposed action to extend the reporting deadline for the TSCA section 8(d) Health and Safety Data Reporting Rule. Specifically, EPA requests comment on the proposed reporting timeline and is soliciting comments on the nature and extent of any reliance interests that may have arisen from the rule.
**III. Statutory and Executive Order Reviews**
Additional information about these statutes and Executive Orders can be found at *https://www.epa.gov/laws-regulations/laws-and-executive-orders.*
**A. Executive Order 12866: Regulatory Planning and Review and Executive Order 13563: Improving Regulations and Regulatory Review**
This action is not a significant regulatory action and was therefore not submitted to the Office of Management and Budget (OMB) for review under Executive Order 12866 (58 FR 51735, October 4, 1993) and 13563 (76 FR 3821, January 21, 2011).
**B. Executive Order 14192: Unleashing Prosperity Through Deregulation**
This action is an Executive Order 14192 deregulatory action. This proposed rule provides burden reduction by providing relief against existing compliance deadlines.
**C. Paperwork Reduction Act (PRA)**
This action does not impose any new information collection burden under the PRA, 44 U.S.C. 3501 *et seq.* OMB has previously approved the information collection activity contained in the existing regulation and has assigned OMB control number 2070-0224 (EPA ICR No. 2703.02). This action does not create any new reporting or recordkeeping obligations and does not otherwise change the burden estimates that were approved.
**D. Regulatory Flexibility Act (RFA)**
I certify that this action will not have a significant economic impact on a substantial number of small entities under the RFA, 5 U.S.C. 601 *et seq.* In making this determination, the EPA concludes that the impact of concern for this rule is any significant adverse economic impact on small entities and that the agency is certifying that this rule will not have a significant economic impact on a substantial number of small entities because the rule relieves regulatory burden on the small entities subject to the rule. This proposed action would extend compliance dates of one data reporting rule and alleviate compliance burden on small entities subject to those actions. We have therefore concluded that this action will relieve regulatory burden for all directly regulated small entities.
**E. Unfunded Mandates Reform Act (UMRA)**
This action does not contain any unfunded mandate of $100 million (adjusted annually for inflation) or more (in 1995 dollars) as described in UMRA, 2 U.S.C. 1531-1538, and does not significantly or uniquely affect small governments. The action imposes no enforceable duty on any state, local, or tribal governments or the private sector.
**F. Executive Order 13132: Federalism**
This action does not have federalism implications as specified in Executive Order 13132 (64 FR 43255, August 10, 1999), because it will not have substantial direct effects on the States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government.
**G. Executive Orders 13175: Consultation and Coordination With Indian Tribal Governments**
This action does not have tribal implications as specified in Executive Order 13175 (65 FR 67249, November 9, 2000) because it will not have substantial direct effects on tribal governments, on the relationship between the Federal government and the Indian tribes, or on the distribution of power and responsibilities between the Federal government and Indian tribes. This action does not impose substantial direct compliance costs on federally recognized Indian tribal governments. Thus, Executive Order 13175 does not apply to this action.
**H. Executive Order 13045: Protection of Children From Environmental Health Risks and Safety Risks**
Although this action does not concern an environmental health or safety risk, the information obtained from the reporting required by this rule will be used to inform the Agency's decision-making process regarding chemical substances to which children may be exposed. This information will also assist the Agency and others in determining whether the chemical substances included in this proposed rule present potential risks, allowing the Agency and others to take appropriate action to investigate and mitigate those risks.
EPA interprets Executive Order 13045 (62 FR 19885, April 23, 1997) as applying only to regulatory actions considered significant under section 3(f)(1) of Executive Order 12866 and that concern environmental health or safety risks that EPA has reason to believe may disproportionately affect children, per the definition of “covered regulatory action” in section 2-202 of Executive Order 13045.
Since this is not a “covered regulatory action,” E.O. 13045 does not apply. However, the Policy on Children's Health does apply.
**I. Executive Order 13211: Actions Concerning Regulations That Significantly Affect Energy Supply, Distribution, or Use**
This action is not subject to Executive Order 13211 (66 FR 28355, May 22, 2001), because it is not a significant regulatory action under Executive Order 12866.
**J. National Technology Transfer and Advancement Act (NTTAA)**
This action does not involve technical standards under the NTTAA section 12(d), 15 U.S.C. 272.
**List of Subjects in 40 CFR Part 716**
Environmental protection, Chemicals, Hazardous substances, Health and safety, Reporting and recordkeeping requirements.
Lee Zeldin,
Administrator.
