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.
