Incident Narrative

"POST-INCIDENT INVESTIGATION REVEALED A 2-INCH PE PIPE WAS MOST LIKELY PUNCTURED WHEN A RESIDENT'S PLUMBER USED A MECHANICAL TOOL TO CLEAR A CLOGGED SEWER LATERAL. THE GAS PIPE HAD BEEN INADVERTENTLY CROSS-BORED THROUGH THE SEWER LATERAL BY THE ORIGINAL GAS LINE INSTALLATION CONTRACTOR IN 2017. CAMERA INSPECTIONS WERE PERFORMED ON THE REMAINDER OF THE ORIGINAL INSTALLATION PROJECT AND NO ADDITIONAL AREAS WERE DISCOVERED TO HAVE CROSS-BORES. TEXAS GAS SERVICE COMPANY'S PUBLIC AWARENESS TO THE AFFECTED PUBLIC INCLUDES OUTREACH ON THE POSSIBILITY OF CROSS-BORES. SUPPLEMENTAL INFORMATION 5/19/23 TGS SELECTED 20:40 AS THE EARLIEST LOCAL TIME THAT THE INCIDENT REPORTING CRITERIA WERE MET BASED ON ITS PRELIMINARY EVALUATION THAT NATURAL GAS FROM ITS SYSTEM WAS LIKELY TO HAVE CAUSED THE FIRE AND THE PRESUMPTION THAT ONE OF THE HOME'S OCCUPANTS COULD BE ADMITTED TO THE HOSPITAL FOR CARE OR THAT THE TOTAL COST OF DAMAGES COULD EXCEED $129,300. WHILE THE ORIGINAL TELEPHONIC REPORT TO THE NATIONAL RESPONSE CENTER NOTED THE POTENTIAL THAT AN EXPLOSION HAD OCCURRED, THE INVESTIGATION MADE NO OBSERVATIONS OR FORMAL REPORTS OF AN EXPLOSION."
