PHMSA Issues NPRM for Gas Pipeline Leak Detection and Repair

[Docket No. PHMSA-2021-0039]

PHMSA has issued a new Notice of Proposed Rulemaking (NPRM) intended to reduce methane emissions from new and existing pipelines, including gas transmission, distribution, regulated gas gathering (Types A, B, C and offshore), underground natural gas storage facilities, and LNG facilities. 

Among the proposed amendments for Part 192-regulated gas pipelines are:

  • New definitions, including leaks or hazardous leaks,
  • Expanded leakage survey and patrolling requirements,
  • Performance standards for advanced leak detection programs,
  • Leak grading and repair criteria with mandatory repair timelines,
  • Requirements for mitigation of emissions from blowdowns,
  • Pressure relief device design, configuration, and maintenance requirements,
  • Expanded hazardous leak detection for pressure testing,
  • Clarified requirements for investigating failures, and
  • Expanded reporting requirements.

Comments will be due 60 days after this NPRM is published in the Federal Register. Submit comments through the E-Gov Website for Docket #PHMSA-2021-0039.
