Gas Pipeline Leak Detection and Repair Act of 2025

Senator Edward J. Markey (D-Mass.), along with Senator Ben Ray Lujan (D-N.M.), Representatives Scott Peters (D-Calif.), and Troy A. Carter, Sr. (D-La.), introduced legislation to modernize decades-old gas pipeline leak detection and repair requirements. The Gas Pipeline Leak Detection and Repair Act of 2025 aims to reduce methane emissions, improve pipeline safety, and keep communities healthy.

Key Takeaways:

• The legislation proposes to update decades-old leak detection and repair requirements for natural gas pipelines, enhancing safety by reducing methane emissions and preventing costly and dangerous leaks.
• The bill would codify a Pipeline and Hazardous Materials Safety Administration (PHMSA) rule that increases the frequency of leak surveys, requires the use of advanced leak detection technology, and revises reporting minimum thresholds for unintentional methane emissions.
• The PHMSA rule was drafted with robust stakeholder input and support in response to section 113 of the PIPES Act of 2020, and the new requirements are based on 28 consensus recommendations from representatives of the pipeline sector.
• The legislation would also establish clarified requirements for the repair of leaks that pose a risk to public safety or the environment and encourage the use of equipment for methane capture.
• The bill has the support of Pipeline Safety Trust, Environmental Defense Fund, Moms Clean Air Force, Natural Resources Defense Council, and Appalachian Voices.
• The proposed legislation aims to protect communities living near gas pipelines, reduce methane waste, and promote U.S. innovation in new technologies.

Statistics:

• Natural gas pipelines leak enough each year to meet the gas needs of nearly 2.5 million homes (Environmental Defense Fund).
• The proposed legislation would reduce methane emissions and prevent costly and dangerous leaks in gas pipelines.
• The bill aims to update decades-old leak detection and repair requirements for natural gas pipelines, safeguarding public health and the environment.
