Incident Narrative
"TEXAS GAS'S MIDLAND 3 COMPRESSOR STATION YARD PIPING WAS BEING RE-PRESSURIZED FOLLOWING CONSTRUCTION AND ROUTINE MAINTENANCE ACTIVITIES. THE AFFECTED AREA WAS PRESSURIZED LATE IN THE DAY AND LEFT OVERNIGHT. UPON RETURN ON 10/15/21 AT APPROXIMATELY 7:00 AM, BUBBLING WAS DISCOVERED BY THE AREA MANAGER AS HE PASSED THE AREA. THE SUSPECTED LEAK AREA WAS ISOLATED AND BLOWN DOWN. THE LEAK CAUSE IS SUSPECTED TO BE INTERNAL CORROSION DUE TO SLUDGE. FOR THIS REASON, TEXAS GAS DECIDED TO REPLACE THE PIPE BETWEEN FITTINGS AND INSTALL A LOW-POINT DRAIN. ONCE THIS DECISION WAS MADE, IT WAS DETERMINED THAT THE COST OF REPAIRS WOULD EXCEED THE $122,000 THRESHOLD FOR INCIDENT REPORTING AND NOTIFICATION WAS MADE TO THE NRC. TEXAS GAS ALSO SCANNED THE ENTIRE HEADER AND INSTALLED A SLEEVE ON AN AREA WHERE CORROSION WAS IDENTIFIED. THE REPAIRS WERE COMPLETED ON 11/11/21. IN RESPONSE TO PART G, QUESTION 13, WHILE THIS PARTICULAR LOCATION IS NOT MONITORED WITH CORROSION COUPONS, TEXAS GAS DOES MONITOR FOR CORROSION IN THE STORAGE FIELD."
