PHMSA reopened the public comment period on 13 pipeline safety rulemaking proposals, moving the deadline from August 31 to September 4, 2026.

PHMSA's Gas Pipeline Advisory Committee (GPAC) and Liquid Pipeline Advisory Committee (LPAC) held a joint meeting on July 30, 2026, to discuss the 13 proposed rules for gas and liquid pipelines, covering topics from special permit conditions and right-of-way patrols to remote valves and limitations on welding. PHMSA had set the original comment deadline, August 31, when it announced the meeting on July 17, 2026.

After the meeting, the Pipeline Safety Trust and the Environmental Defense Fund asked PHMSA for an additional 30 days to comment, which would have pushed the deadline to October 1, 2026. PHMSA reopened the comment period through September 4 instead. The agency said it will consider late-filed comments "to the extent practicable," consistent with 49 CFR 190.323.

Comments go under docket number PHMSA-2026-1156, plus the docket tied to each specific proposal. Some of the rulemakings under discussion:

Special permit conditions PHMSA-2025-0135 Tie special permit conditions directly to the provision being waived
