Incident Narrative

COLORADO INTERSTATE GAS (CIG) TRANSMISSION PERSONNEL, WHILE INSTALLING PIPELINE MARKERS, DISCOVERED AN AREA OF DEAD VEGETATION AND DISCOLORED SOIL IN THE VICINITY OF ITS 16"" 52A PIPELINE IN MORGAN COUNTY, COLORADO. LEAK DETECTION EQUIPMENT CONFIRMED A NATURAL GAS LEAK. EXCAVATION REVEALED A VERY SMALL CRACK IN THE PIPE'S LONG SEAM TO BE THE SOURCE OF THE LEAK, ATTRIBUTABLE TO A LACK OF WELD FUSION IN THE LONG SEAM. THE ANOMALY WAS CUT OUT AND REPLACED WITH A NEW CYLINDER OF PIPE. THE PIPELINE WAS THEN PLACED BACK INTO OPERATION.
