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 In FR Doc. 2025-10812 appearing at 90 FR 24977 in the Federal Register of Friday, June 13, 2025 (FRL-11825-02-OCSPP), the following corrections are made to the regulatory text: [[Page 34185]] PART 9--[Corrected] 0
