Incident Narrative
A PROPANE LEAK WAS EXPERIENCE FROM THE ELLA BROWNSVILLE PIPELINE. A LOCAL LANDOWNER CONTACTED THE OPERATOR WHEN HE OBSERVED ICE BUILD-UP ON THE GROUND. UPON FURTHER INVESTIGATION BY THE PIPELINE TECHNICIAN, AN UNDERGROUND LEAK WAS DISCOVERED. THERE WAS NO FIRE, EXPLOSION, OR LOSS OF PROPERTY. UPON NOTIFICATION TO THE HOUSTON CONTROL CENTER, THE FEED INTO THE PIPELINE FROM SUPPLIERS WAS IMMEDIATELY SHUTDOWN, AND THE CONSUMER WAS ASKED TO TAKE AS MUCH PROPANE AS POSSIBLE TO BRING THE LINE PRESSURE DOWN. CLEARING OF AN 8 MILE SECTION OF LINE COMMENCED THAT EVENING, AND THE LINE WAS CLEARED TO A FLARE IN PREPARATION FOR EXCAVATION, ANALYSIS AND REPAIR OF THE LEAK SITE. IT WAS DETERMINED THAT THE LEAK ORIGINATED FROM A CORROSION PINHOLE, METALLURGICAL ANALYSIS DETERMINED THAT IT WAS MICROBIOLOGICALLY INDUCED CORROSION. TO PREVENT RECURRENCE, DOW REMOVED APPROXIMATELY 20-FEET OF PIPE, INCLUDING THE LEAK SITE, AND REPLACED IT WITH NEW PIPE BEFORE PLACING BACK IN SERVICE.
