General Discussion</HD> Through this DFR, PHMSA is incorporating by reference an update to a voluntary, consensus industry technical standard already incorporated by reference within the pipeline safety regulations (PSRs, 49 Code of Federal Regulation (CFR) parts 192 and 195. Specifically, PHMSA is updating the referenced edition of industry standard ASTM A381/A381M, Standard Specification for Metal-Arc-Welded Carbon or High-Strength Low-Alloy Steel Pipe for Use with High-Pressure Transmission System to the 2023 version. This specification covers metal-arc-welded steel pipe for use with high pressure transmission systems, specifically with respect to fabrication of fittings and accessories for compressor or pump-station piping. The specification also sets forth required chemical compositions for carbon steel, and the tensile properties of finished pipes. References to the 2023 version of the standard will replace existing references within 49 CFR 192.113, appendix B to part 192, and § 195.106(e) to ASTM A381/A381M-18, “Standard Specification for Metal-Arc-Welded Carbon or High-Strength Low-Alloy Steel Pipe for Use with High-Pressure Transmission System,” approved November 1, 2018. This updated standard will maintain or improve public safety, prevent regulatory confusion, and reduce compliance burdens on stakeholders. The National Technology Transfer and Advancement Act (NTTAA) of 1995 (15 United States Code (U.S.C.) 272 (note)) directing Federal agencies to “use technical standards developed by voluntary consensus standard bodies instead of government-developed technical standards,” “when practical and consistent with applicable laws.” Consistent with that mandate, PHMSA incorporates more than 80 industry standards by reference into the PSRs; however, many standards become outdated over time as new editions become available. By updating these standards, PHMSA ensures better alignment of the PSRs with the latest innovations in operational and management practices, materials, testing, and technological advancements; enhances compliance by avoiding conflict between different versions of the same industry standards; and facilitates safety-focused allocation of resources by pipeline operators. PHMSA technical experts have also evaluated the changes in the updated standard and concluded that it will either maintain or enhance the protection of public safety. PHMSA further concludes that the direct final rule's updated standard is technically feasible, reasonable, cost-effective, and practicable because of its respective anticipated commercial and public safety benefits; and because the benefits better support PHMSA's safety priorities compared to alternatives, thereby justifying any associated compliance costs. <HD SOURCE="HD2">Availability of Materials to Interested Parties</HD> Pursuant to section 24 of the Pipeline Safety, Regulatory Certainty, and Job Creation Act of 2011 (Pub. L. 112-90, 49 U.S.C. 60102(p), as amended), “the Secretary may not issue a regulation pursuant to this chapter that incorporates any documents or portions thereof unless the documents or portions thereof are made available to the public, free of charge.” On November 7, 2014, the Office of the Federal Register issued a final rule that revised 1 CFR 51.5 to require every Federal agency to “[d]iscuss, in the preamble of the proposed rule, the ways that the materials it proposes to incorporate by reference are reasonably available to interested parties or how it worked to make those materials reasonably available to interested parties[.]” PHMSA consequently has negotiated agreements to make viewable copies of the standards available to the public at no cost. ASTM International (ASTM) agreed to the public access requirements of the statutory mandate discussed above. The organization's mailing address and website is listed in 49 CFR parts 192 and 195. The ASTM standards incorporated in this final rule are available from the following website: <E T="03">https://www.astm.org/standards-and-solutions/standards-and-publications/reading-room.</E> Additional information regarding standards availability can be found at <E T="03">https://www.phmsa.dot.gov/standards-rulemaking/pipeline/standards-incorporated-reference.</E> <HD SOURCE="HD2">Commenting</HD> <E T="03">Instructions:</E> Please include the docket number PHMSA-2025-0124 at the beginning of your comments.
