Significant New Use Rules on Certain Chemical Substances (23-
3.5e); Correction
AGENCY: Environmental Protection Agency (EPA).
ACTION: Final rule; correction.
-----------------------------------------------------------------------
SUMMARY: EPA is making corrections to a final rule that appeared in the
Federal Register of June 13, 2025 (FR Doc. 2025-10812). The final rule
established significant new use rules (SNURs) under the Toxic
Substances Control Act (TSCA) for chemical substances that were the
subject of premanufacture notices (PMNs) and Orders issued by EPA
pursuant to TSCA.
DATES: The final rule corrections are effective on August 12, 2025.
ADDRESSES: The docket for this action, identified under docket
identification (ID) number EPA-HQ-OPPT-2023-0328, is available online
at <a href="https://www.regulations.gov">https://www.regulations.gov</a> or in person at the Office of Pollution
Prevention and Toxics Docket (OPPT Docket) in the Environmental
Protection Agency Docket Center (EPA/DC). Please review the visitor

SUPPLEMENTARY INFORMATION: This action corrects certain regulatory
amendments established in the final rule that appears in the Federal
Register of June 13, 2025 (90 FR 24977 (FRL-11825-02-OCSPP)) as listed
here:
1. The amendment to the table in 40 CFR part 9 is removed because
EPA subsequently issued a separate amendment to 40 CFR part 9 that
makes this change obsolete and unnecessary. See FR Doc. 2025-11573 (90
FR 27785, June 30, 2025 (FRL-12001-01-OCSPP)).
2. In the table of content, heading and regulatory provision for 40
CFR 721.11839 and 721.11840, the word ``ethandiyl'' in the name of the
chemical substance was misspelled and is corrected to read
``ethanediyl''.
3. In the regulatory provision for 40 CFR 721.11839 and 721.11840,
the word ``floatation'' was misspelled and is corrected to read
``flotation''.
4. In the regulatory provision for 40 CFR 721.11858, the phrase
``and regulated blendstocks (40 CFR part 1090)'' is repeated in the
second sentence and is being removed to eliminate the redundancy.
5. In the table of content, heading and regulatory provision for 40
CFR 721.11861, the word ``hetropolycyclic'' in the name of the chemical
substance was misspelled and is corrected to read ``heteropolycyclic''.
The Agency is not providing a public comment opportunity prior to
promulgation of these technical corrections, because such public
comment is unnecessary under 5 U.S.C. 553(b)(B) of the Administrative
Procedure Act (APA). The corrections established in this action are
very minor and non-substantive technical corrections to regulations;
thus, the corrections would not substantively alter the regulations
established in the final rule in a way that would be of interest to the
regulated community or the public. Therefore, pursuant to the APA
section 553(b)(B), EPA finds good cause to promulgate these technical
corrections without notice and comment.
Corrections

Register of Friday, June 13, 2025 (FRL-11825-02-OCSPP), the following
