Narrative
Magellan personnel were changing out a corrosion coupon. To do so, product needed to be drained from the pig trap. The pig trap pressure warning device ("pwd") was loosened to allow product to drain. When returning to service, the pwd was hand tightened, but not wrench tightened. The pipeline was restarted and the equipment was checked during the next hour for leaks. Sometime after the line was returned to service, the mainline valve upstream from the pwd slowly leaked by, filling the pig trap until product was released from the pwd into containment. The release was stopped by wrench tightening the pwd. Product was recovered, and approximately 10 cubic yards of impacted soil was remediated. This supplemental-final report was filed to make changes in parts b11 and c6 at the request of the minnesota office of pipeline safety.
