Narrative
On june 5 at 08:38 local time, the edmonton control center experienced a gas alarm on unit 5.2 at the mackinaw city station. Onsite plm personnel were notified to investigate alarm. The line was down at the time due to a normal operating shutdown at the superior terminal for pigging on line 5. It was discovered that a 3/4" nipple on the unit had cracked due to normal wear and tear. At the time of the incident ngl was across the station. The unit was isolated and the line was restarted at a reduced pressure and operated until crude oil was across the station to facilitate repair. Once crude had crossed the station later that day, the unit was flushed, drained and the cracked 3/4" nipple on the unit was replaced. Approximately 15 yards of soil has been disposed of at an approved landfill due to odor not saturated with product.
