SUPPLEMENTARY INFORMATION:
On April 24, 2026, PHMSA published a DFR titled “Pipeline Safety: Standards Update—ASTM A372/A372M” (91 FR 22008). The DFR amended regulations at 49 CFR part 192 to incorporate the reapproved 2025 edition of ASTM A372/A372M, Standard Specification for Carbon and Alloy Steel Forgings for Thin-Walled Pressure Vessels (ASTM A372/A372M) by reference. Reference to the reapproved 2025 edition of ASTM A372/A372M will replace existing references within § 192.177 to ASTM A372/A372M-20e1, Standard Specification for Carbon and Alloy Steel Forgings for Thin-Walled Pressure Vessels, approved March 1, 2020.
PHMSA issued the DFR under the procedures set forth at 49 CFR 190.339. In accordance with those procedures, PHMSA stated in the DFR that if no adverse comments were received, the DFR would become effective on January 1, 2027. PHMSA did not receive any
( printed page 48301)
comments that warranted withdrawal of the DFR; therefore, this rule will become effective as scheduled.
Issued in Washington, DC under authority delegated in 49 CFR 1.97.
