"ON APRIL 30, 2021, AT APPROXIMATELY 7:00 PM, A THIRD PARTY REPORTED TO ENTERPRISE THERE WAS BUBBLING AT A METER SITE. AT 7:30 PM, AN ENTERPRISE TECHNICIAN ARRIVED ON SITE AND CONFIRMED IT WAS NATURAL GAS BUBBLING FROM THE GROUND NEAR SEVERAL PIPELINES, INCLUDING ENTERPRISE LINE 225. ON MAY 1, ENTERPRISE EXPOSED THE LEAK AREA AND IDENTIFIED A MINOR LEAK FROM A TEE ON LINE 225. THE LEAK SITE WAS MONITORED WHILE ENTERPRISE DEVELOPED A PLAN TO REPAIR THE LEAK. ON MAY 4, AT 9:55 AM, ENTERPRISE DETERMINED THAT THE CHOSEN REPAIR METHOD WOULD EXCEED THE $122,000 REPORTING THRESHOLD AND NOTIFIED THE NRC AND TEXAS RRC. THE RRC WAS NOTIFIED AT 10:30 AM AND ASSIGNED INCIDENT #2422. A STOPPLE AND BYPASS WAS INSTALLED AND THE TEE WAS REMOVED AND REPLACED. LAB ANALYSIS DETERMINED THE LEAK WAS THE RESULT OF A CRACK THAT INITIATED AT THE OD TOE OF THE FILLET WELD OF THE 10-INCH TAP TO THE 36-INCH PIPE. THE CRACK APPEARED TO BE STRESS INITIATED, LIKELY THE RESULT OF A LOADING EVENT."
