Incident Narrative
"ON MARCH 11, 2010 AT APPROXIMATELY 10 AM LOCAL TIME, A CONTRACT INSPECTOR COMPLETING VALVE INSPECTIONS AT THE SUPERIOR TERMINAL NOTICED COAGULATED OIL NEAR TANK 15. ENBRIDGE OPERATIONS WAS IMMEDIATELY NOTIFIED AND ARRIVED ON SITE TO INVESTIGATE. THE CONTROL CENTER WAS NOTIFIED, THE VALVE WAS CLOSED AND THE LINE TO TANK 15 WAS TEMPORARILY BYPASSED. DUE TO COLD TEMPERATURES, THE GROUND WAS THAWED TO ALLOW FOR EXCAVATING THE AREA IN QUESTION. UPON INVESTIGATION, IT WAS FOUND THAT THAT THE RELEASE WAS DUE TO CRACKS IN THE AUXILIARY PIPING ASSOCIATED WITH TANK VALVE SV-15. THE CRACKS IN THE AUXILIARY PIPING WERE CAUSED BY STRESSES DUE TO GROUND MOVEMENT FROM FROST HEAVE. THE AUXILIARY PIPING WAS REPLACED AND THE LINE TO TANK 15 AND SV-15 WERE RETURNED TO SERVICE ON MARCH 17, 2010."
