LPAC meeting set for October 21 on breakout tank, remote rectifier and valve inspection NPRMs
A Federal Register notice schedules a virtual Liquid Pipeline Advisory Committee meeting on October 21 to review proposed rules adopting API Std 653 5th edition with risk-based breakout tank inspection intervals, permitting remote rectifier checks on hazardous liquid and CO2 lines, and setting valve inspection at least once a year, not exceeding 15 months. Written statements are due October 7 and post-meeting comments by November 20.
Repair-criteria comment window closes
Comments close on PHMSA's NPRM modernizing repair criteria for gas transmission and hazardous liquid pipelines (FR Doc 2026-13805, published July 8), the first major rewrite of the federal anomaly-response rules in nearly 20 years. PHMSA estimates roughly $390 million in operator savings from model-based anomaly disposition.
Comment period on the 13-rule advisory committee proceedings closes
The reopened comment window on the Gas and Liquid Pipeline Advisory Committee proceedings (Docket PHMSA-2026-1156) closes September 4. The separate repair-criteria NPRM for gas transmission and hazardous liquid lines stays open to September 8.
PHMSA reopens comment period on the 13-rule advisory committee proceedings, to September 4
After Pipeline Safety Trust and EDF asked for 30 more days, PHMSA reopened comments on the joint GPAC/LPAC proceedings covering the 13 modernization NPRMs, but only to September 4 rather than the October 1 requested. Late comments will be considered to the extent practicable; the separate repair-criteria NPRM closes September 8.
