Narrative
At approximately 1:40 pm cdt on june 16, 2015, the pipeline maintenance services crew based at the flanagan terminal was installing a completion plug into a 2" t.D. Williamson (tdw) thread-o-ring (tor) fitting in the vicinity of manifold 201 located at the flanagan terminal. As the 2" control valve was unthreaded from the tor, the completion plug fell to the ground and oil began to be released from the fitting. The edmonton control center was immediately notified and tank line 11 was shut down and any manifold 201 valves connected to the tank 11 header isolated. An initial attempt to install the tor cap while the oil was escaping was unsuccessful, but as the tank valves were closed, the flow of crude oil was stopped and the tor cap was installed. Operations staff at the terminal immediately responded with absorbent boom and absorbent diapers. All oil was contained on site within the secondary containment around manifold 201. Contract resources were mobilized immediately and the clean-up was completed on june 18, 2015. It was estimated that the oil was escaping from the tor fitting for approximately 5 minutes. Due to the recent rain events, there was standing water in the secondary containment which allowed the release oil to spread out quickly. Approximately 50 cubic yards of contaminated soil was removed and disposed of at an approved landfill. All crude (approximately 3 barrels) was recovered, however, none was returned to the system. The pipeline was returned to service/restarted on june 17, 2015 at 7:25 pm cdt.
