A closer look at 15 years of data shows fewer incidents, fewer hazardous leaks, and stronger, more resilient natural gas distribution systems.

Are investments in aging natural gas infrastructure delivering meaningful safety improvements? A July 2026 report from the Future of Heat Initiative (FOHI), Spending and Safety Outcomes in U.S. Gas Distribution Systems – An Assessment of DIMP & PHMSA’s Call to Action, raised that question by arguing that replacement of older cast iron and bare or unprotected steel pipe has not produced industry-wide gains.

The Blacksmith Group tested that conclusion against data from the Pipeline and Hazardous Materials Safety Administration (PHMSA) and individual operators. Its forthcoming report, A 2026 Evaluation of Natural Gas Distribution Pipeline Safety Performance in the United States, finds that the broader record tells a different story. In fact, replacement programs have slowed deterioration, addressed emerging risks, reduced leaks, and lowered both the likelihood and potential severity of catastrophic events.

The Blacksmith Group will release their entire report later this month. For access to the report summary, the report can be found through the Blacksmith Group or NGA.
