Pipeline Safety: Gas Pipeline Leak Detection and Repair **Citation:** 88 FR 31890 **Type / status:** rulemaking / proposed **Agency:** Pipeline and Hazardous Materials Safety Administration **Effective / published:** Not stated / 2023-05-18 PHMSA proposes regulatory amendments that implement congressional mandates in the Protecting our Infrastructure of Pipelines and Enhancing Safety Act of 2020 to reduce methane emissions from new and existing gas transmission pipelines, distribution pipelines, regulated (Types A, B, C and offshore) gas gathering pipelines, underground natural gas storage facilities, and liquefied natural gas facilities. Among the proposed amendments for part 192- regulated gas pipelines are strengthened 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; and clarified requirements for investigating failures. Finally, PHMSA proposes expanded reporting requirements for operators of all gas pipeline facilities within DOT's jurisdiction, including underground natural gas storage facilities and liquefied natural gas facilities. ### Provenance - Official: Yes - Source: - Source ID: `federal-register` - SHA-256: `945fbcbaa39282d8e3f685f41d845d9df61914d6a5cd1337e73befc8a14e0b82` - Retrieved: 2026-08-20T06:04:51.294Z - Document slug: `federal-register-2023-09918` - Related records: 102 ## 2.
