Incident Narrative
"ON THE MORNING OF 1/24/24, A PIPELINE TECHNICIAN DISCOVERED PROPYLENE BEING RELEASED FROM SHELL'S PIPELINE. THE LEAK OCCURRED ON AN EXISTING VALVE BOX INSTALLED ON THE PIPELINE FROM A PRIOR MAINTENANCE ACTIVITY. PROPYLENE WAS RELEASED INTO THE ATMOSPHERE FROM THE LEAK SOURCE. NO ROADS OR HIGHWAYS WERE CLOSED BECAUSE OF THIS RELEASE. **CREATED A SUPPLEMENTAL TO CHANGE THE RELEASE SIZES ON PART A. **2/27/24 ADDITION... THE VALVE IN QUESTION HAD AN ISSUE THAT WAS CAUSING A SMALL SEEPAGE OF PROPYLENE, AN AMOUNT THAT DID NOT MEET REPORTING CRITERIA AT THE TIME IT WAS DISCOVERED AND REPAIRED. TO AVOID AN UNSCHEDULED SHUTDOWN OF THE CHEMICAL PLANT, THE VALVE WAS ENCAPSULATED IN A SPECIALIZED REPAIR CLAMP AS A TEMPORARY REPAIR MEASURE. THE EPOXY SEAL OF THIS TEMPORARY REPAIR CLAMP IS WHAT FAILED. THE LINE WAS REPAIRED BY CUTTING OUT THE VALVE AND REPAIR CLAMP AND INSTALLING NEW PIPE AND A NEW VALVE."
