SUPPLEMENTARY INFORMATION: On July 1, 2025 (90 FR 28097), PHMSA
published a DFR amending its regulations at 49 CFR part 192 to
incorporate by reference the 2024 edition of PPI TR-3, ``Policies and
Procedures for Developing Hydrostatic Design Basis (HDB), Hydrostatic
Design Stresses (HDS), Pressure Design Basis (PDB), Strength Design
Basis (SDB), Minimum Required Strength (MRS) Ratings, and Categorized
Required Strength (CRS) for Thermoplastic Piping Materials or Pipe.''
Reference to the 2024 edition of the standard will replace the existing
reference to PPI TR-3/2012, ``Policies and Procedures for Developing
Hydrostatic Design Basis (HDB), Hydrostatic Design Stresses (HDS),
Pressure Design Basis (PDB), Strength Design Basis (SDB), Minimum
Required Strength (MRS) Ratings, and Categorized Required Strength
(CRS) for Thermoplastic Piping Materials or Pipe,'' issued in November
2012, within 49 CFR 192.121(a).
PHMSA issued the DFR under the procedures set forth at 49 CFR
190.339. In accordance with those provisions, PHMSA stated in the DFR
that if no adverse comments were received, the DFR would become final
and effective on January 1, 2026. PHMSA did not receive any comments
that warranted withdrawal of the DFR; therefore, this rule will become
effective as scheduled.
Issued in Washington, DC, on September 30, 2025, under the
authority designated in 49 CFR 1.97.
Benjamin D. Kochman,
Deputy Administrator.
