Incident Narrative
"ON MARCH 20, DURING AN INTEGRITY EXCAVATION AT MILEPOST 951, A CONTRACT EMPLOYEE NOTICED CONTAMINATED SOIL WITHIN THE EXCAVATION NEAR A PLIDCO SLEEVE. THE INSPECTOR ON SITE CONTACTED THE BEMIDJI PLM SUPERVISOR WHO THEN NOTIFIED THE EDMONTON CONTROL CENTER AND THE PIPELINES IN THE IMMEDIATE AREA WERE SHUT DOWN. THE CONTROL CENTER WAS CALLED ONCE PLM RESOURCES ARRIVED ON SITE AND CONFIRMED IT WAS NOT JUST A HISTORIC LEAK. ONCE THE LEAK WAS CONFIRMED TO BE ISOLATED TO LINE 3, THE REMAINING LINES WERE RESTARTED. FURTHER INVESTIGATION REVEALED THAT THE LEAK WAS CAUSED BY A FAILED SEAL WELD ON THE PLIDCO SLEEVE CLAMP NUT. THE WELD WAS REPAIRED AND THE LINE WAS RETURNED TO SERVICE THE FOLLOWING DAY. APPROXIMATELY 3 YARDS OF CONTAMINATED SOIL CAUSED BY THE LEAK ON MARCH 20, 2012 HAS BEEN REMOVED FROM THE SITE."
