### Pipeline Safety: Joint Meeting of the Gas and Liquid Pipeline Advisory Committees

*Notice* — Transportation Department · Pipeline and Hazardous Materials Safety Administration

On July 17, 2026, PHMSA published a Federal Register notice titled: "Pipeline Safety: Joint Meeting of the Gas and Liquid Pipeline Advisory Committees," which provided an opportunity for public comment by August 31, 2026, on the proceedings of the Gas and Liquid Pipeline Advisory Committees meeting related to 13 notices of proposed rulemakings (NPRM). These proposed rules covered topics such as special permit conditions, in-plant piping, incidental gathering lines, coating damage assessments, atmospheric corrosion, class change pressure tests, maximum allowable operating pressure reconfirmation, operator identification notifications, limitations on welding, remote valves, the property damage definition, right-of-way patrols, and reporting deadlines. PHMSA received requests from stakeholders to extend the comment period. Based on those requests, PHMSA is reopening the comment period for the joint Pipeline Advisory Committee (PAC) proceedings related to the 13 regulatory modernizing NPRMs to September 4, 2026.
