Atmos Energy Statement

DALLASJan. 12, 2021 – Today the National Transportation Safety Board (NTSB) held a public hearing to determine the probable cause of the natural gas explosion in Dallas that occurred on Feb. 23, 2018.  We again express our deepest sympathies to the Rogers family who remain in our thoughts and prayers. 

We appreciate the work of the NTSB, Dallas Fire-Rescue, Dallas Police Department, Texas Railroad Commission, Pipeline and Hazardous Materials Safety Administration, and our employees who assisted with the investigation of the accident.   

Our number one priority is the safety of the public, our employees, and our natural gas distribution system.  Our commitment to safety is evident in our people, policies, practices, and procedures, and we are resolved to learn from this tragic accident.  

We are reviewing the complete findings and recommendations released today by the NTSB.  We believe that the probable cause is reflected in the NTSB finding that the natural gas main was damaged by excavation equipment.  

Unreported third party damage caused the pipe to crack and leak.

The field investigation and lab reports confirm the pipe was dented, gouged, and bent by a third party excavator during the installation of a sewer lateral in 1995 or 1996.

The pipeline was in otherwise good condition — coated and protected from corrosion — as shown by the examination at the NTSB lab after the accident. NTSB investigators observed a “hard deposit” — not corrosion — covering a dent and other damaged areas.  When the hard deposits were removed, each of the areas contained at least one major gouge in the metal.

But for the unreported damage, the pipe would not have failed.

Damage Prevention Safety Recommendations

Because third party damage remains one of the greatest threats to natural gas distribution systems and we are accountable for delivering safe and reliable service to our customers and our communities, we have been and will continue to be a champion for damage prevention.  Excavators should notify 911 and then our emergency line (1.866.322.8667) if they nick, scrape, or dent a natural gas pipeline.

The NTSB recognized that third party damage is a dominant cause of accidents across the industry and that there is work to do.  We recommend that the NTSB continue to study ways to further reduce the risk that third party excavation damage goes unreported.

Ongoing Safety Initiatives

We are committed to continuous improvement on our journey to achieve our vision to be the safest provider of natural gas services. Our focus on safety has continued throughout this investigation, including voluntary initiatives to reduce the risk of third party damage to our pipelines. 

Our Party Submission to the NTSB, a copy of which can be found on this page containing more information about the investigation, contains additional safety initiatives that Atmos Energy has undertaken.
