UPON THIS DETERMINATION THE NRC WAS NOTIFIED AND TX RRC PIPELINE SAFETY WAS NOTIFIED (INCIDENT 1170). IN AUGUST 2015 AN IN LINE INSPECTION (ILI) WAS PERFORMED ON THE LINE SEGMENT. PERMANENT REPAIR BY CUT OUT AND REPLACEMENT OF THE FAILED PIPE WAS DELAYED UNTIL THE ILI VENDOR REPORT WAS RECEIVED AND THIS REPLACEMENT COULD BE ACCOMPLISHED IN THE COURSE OF OTHER PIPE REPLACEMENT AND REPAIR WORK IN RESPONSE TO THE ILI RESULTS.
