On April 24, 2026, PHMSA published a DFR titled “Pipeline Safety: Standards Update—ASTM F1055” (91 FR 21997).

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.
