Incident Narrative
"TENNESSEE GAS PIPELINE (TGP) COMPANY OPERATIONS PERSONNEL DISCOVERED INDICATIONS OF WHAT APPEARED TO BE A NATURAL GAS LEAK DURING THEIR WORK RELATIVE TO ANOMALY DIGS FOLLOWING THE RESULTS OF A SMART PIG RUN ON TGP'S 500-1 PIPELINE IN WAYNE COUNTY, TN. EXCAVATION IN THE VICINITY OF THE SUSPECTED LEAK REVEALED A CRACK FROM WHICH GAS WAS LEAKING IN TGP'S 2"" LATERAL LINE NEAR THE TAP OF ITS 500-1 PIPELINE. THE APPARENT CAUSE OF THE LEAK WAS ASSYMETRICAL LOADING (I.E. SETTLEMENT) OF THE SOIL BETWEEN THE CARRIER PIPE AND THE TAP LINE, WHICH RESULTED IN EXCESSIVE STRESSES ON THE 2"" PIPE."
