Incident Narrative
"DURING NORMAL OPERATIONS, MAGELLAN PERSONNEL HEARD A SHARP NOISE COMING FROM THE VICINITY OF THE LOADING RACK MANIFOLD AND UPON INVESTIGATION DISCOVERED A GASKET HAD FAILED ON A 3-INCH FLANGE ON A VALVE ON A LINE IN THE TRANSFER MANIFOLD, RESULTING IN THE RELEASE. THE MANIFOLD WAS PROMPTLY SHUT DOWN AND THE GASKET REPLACED. THE FAILED GASKET WAS SENT TO A LABORATORY FOR ANALYSIS. THE ANALYSIS PROVIDED SEVERAL POSSIBLE CAUSES FOR THE RELEASE, NON CONCLUSIVE. HOWEVER, MAGELLAN BELIEVES THE REASON WAS DUE TO UNDER-TORQUING RELATED TO THE CAST IRON VALVE INVOLVED IN THE FAILURE. CONSEQUENTLY, ALL CAST IRON VALVES AT THE LOCATION WERE REMOVED FROM SERVICE. THE IMPACTED SOIL HAS BEEN EXCAVATED AND ANALYZED IN ACCORDANCE WITH COMPANY AND STATE STANDARDS."
