On May 5, 2023, the Pipeline and Hazardous Materials Safety Administration (PHMSA) released the pre-publication version of a notice of proposed rulemaking (NPRM) titled “Gas Pipeline Leak Detection and Repair.” PHMSA published the NPRM in response to section 113 of the Protecting our Infrastructure of Pipelines and Enhancing Safety Act of 2020 (PIPES Act). Section 113 of the PIPES Act directed PHMSA to promulgate final regulations by December 27, 2021, requiring operators of gas transmission, distribution pipelines, and certain gathering lines to conduct leak detection and repair programs.
PHMSA proposes to amend 49 CFR Parts 191, 192, and 193 to: increase the frequency of leakage survey and patrolling requirements; introduce leakage survey and repair requirements for liquefied natural gas (LNG) facilities; require grading and repairs of leaks; reduce the use of blowdowns and intentional venting; impose design, configuration, and maintenance requirements for relief devices to reduce emissions; expand reporting requirements; and require that Type A, B, and C gathering lines submit geospatial pipeline location data to the National Pipeline Mapping System (NPMS). PHMSA proposes a six-month effective date for this rulemaking.
Comments on the NPRM are due on July 17, 2023.
Scope
Among other notable features of the proposal, the scope of this NPRM extends beyond the Section 113 congressional mandate by including Type C gathering lines, underground natural gas storage facilities, and LNG facilities. The statutory mandate was limited to regulated gathering lines in a Class 2, 3, or 4 location, and new and existing gas transmission and distribution pipelines. …
