SUNOCO PIPELINE L.P.

Incident Narrative

ON MAY 28, 2015 LOCAL OPERATING PERSONNEL WERE NOTIFIED THAT A LAND OWNER HAD CALLED SPLP AND INDICATED THERE WERE SIGNS OF A POSSIBLE RELEASE ON HIS PROPERTY. COMPANY PERSONNEL WERE DISPATCHED TO THE SITE. UPON FURTHER INVESTIGATION AND EXCAVATION IT WAS DETERMINED THERE WAS AN EXTERNAL CORROSION PINHOLE LEAK IN THE 8"" HEBERT TO ALDINE REFINED PRODUCTS LINE. A PLIDCO CLAMP WAS INSTALLED TO PREVENT FURTHER LEAKAGE AND SOIL CONTAMINATION. CREWS WERE DISPATCHED TO CONTAIN AND REMOVE THE CONTAMINATED SOIL. ON MAY 9, 2015 IT WAS DETERMINED THAT THE COST OF ENVIRONMENTAL REMEDIATION AND PERMANENT REPAIRS WOULD EXCEED $50,000. 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. ENVIRONMENTAL REMEDIATION EFFORTS WERE ALSO EXTENDED DUE TO THE LEVEL OF SOIL CONTAMINATION AND REMOVAL EFFORTS. FINAL COSTS WERE DETERMINED IN THE 4TH QUARTER OF 2016.
