The rule finalized National Primary Drinking Water Regulations under the Safe Drinking Water Act for five individual per- and polyfluoroalkyl substances (PFAS): perfluorooctanoic acid (PFOA), perfluorooctane sulfonic acid (PFOS), perfluorohexane sulfonic acid (PFHxS), perfluorononanoic acid (PFNA), hexafluoropropylene oxide dimer acid (HFPO-DA, commonly known as GenX Chemicals). The rule finalized a NPDWR for two or more mixtures of PFNA, PFHXs, HFPO-DA and perfluorobutane sulfonic acid (PFBS). This document corrects formatting and entry designations in the final regulation. </SUM> <EFFDATE> <HD SOURCE="HED">DATES:</HD> Effective on June 25, 2024. </EFFDATE> <HD SOURCE="HED">ADDRESSES:</HD> The EPA has established a docket for this action under Docket ID No. EPA-HQ-OW-2022-0114.

Does this action apply to me?</HD> This action makes formatting changes for the incorporation of the April 26, 2024, final PFAS National Primary Drinking Water Regulation into the Code of Federal Regulations. The agency included in the April 26, 2024, final rule a list of those entities that may be potentially affected by the final PFAS National Primary Drinking Water Regulation. <HD SOURCE="HD1">II. What does this correction do?</HD> The EPA issued a final rule in the <E T="04">Federal Register</E> on April 26, 2024 (89 CFR 32532) (FRL 8543-02-OW), finalizing National Primary Drinking Water Regulations under the Safe Drinking Water Act for PFAS: PFOA, PFOS, PFHxS, PFNA, HFPO-DA, and as well as two or more mixtures of PFNA, PFHXs, HFPO-DA and PFBS. The EPA inadvertently listed incorrect entry designations in § 141.61. This document corrects the designation of entries in the tables in § 141.61(c)(1) and § 141.61(c)(2). With the corrections to § 141.61(c)(1) and § 141.61(c)(2), the subsequent tables in § 141.61(c) are also renumbered; tables 5 and 6 are changed to tables 3 and 4. These corrections to § 141.61 are also now reflected appropriately in amendatory instructions 7 and 8. This document corrects the final regulation. <HD SOURCE="HD1">III. Why is this correction issued as final rule?</HD> Section 553 of the Administrative Procedure Act (APA) (5 U.S.C. 553(b)(3)(B)) provides that, when an agency for good cause finds that notice and public procedure are impracticable, unnecessary, or contrary to the public interest, the agency may issue a final rule without providing notice and an opportunity for public comment. The EPA has determined that there is a good cause for making this correction final without prior proposal and opportunity for comment, because the EPA inadvertently listed the designation of entries incorrectly in § 141.61 in the document published in the <E T="04">Federal Register</E> . The EPA finds that this constitutes good cause under 5 U.S.C. 553(b)(3)(B). <HD SOURCE="HD1">Corrections</HD> In FR Doc. 2024-07773 beginning on page 32532 in the <E T="04">Federal Register</E> of April 26, 2024, the EPA is making the following corrections: <SECTION> <SECTNO>§ 141.60</SECTNO> <SUBJECT> [Corrected]</SUBJECT> </SECTION> <REGTEXT TITLE="40" PART="141"> 1.
