Narrative
On april 30, 2020 at 07:53 cdt, griffith terminal personnel notified the edmonton control center (ecc) of a suspicious odor and the terminal was shutdown. An investigation of the facility was initiated requiring all tanks to be climbed. It was determined that the odor originated from an open vent on tank 76 due to high water on the roof while it was at working bottoms. The remainder of the tanks were climbed in order to give ecc approval to restart the terminal. At approximately 09:00 cdt, a griffith terminal maintainer climbed tank 71 and discovered an active release on the tank roof. Following several heavy rains, the water on the external floating tank roof displaced the roof causing the pin holes on the top of the center tank legs to drop below the product level in the tank spilling oil onto the roof. The tank was isolated and locked out, and the approval to restart the terminal was given to ecc. Pipeline maintenance personnel were onsite and initiated cleanup of the tank roof. A triple filter system was installed on the roof drain to safely drain water from the roof. After cleanup was complete, tank 71 was returned to service.
