Narrative
On august 4, 2017 at approximately 11:06 am edt, the bay city plm supervisor received a call from the bay city electrical technician stating that the line 5 sending trap door was leaking. Approximately 30 gallons of product leaked onto the ground and remained on site in the immediate area of the sending trap. The bay city plm crew was dispatched immediately to drain and repair the trap door. Preliminary investigation determined that the o-ring on the trap door had failed resulting in the release. A gemini smart tool had been launched successfully the day prior and the o-ring replaced by the bay city plm. During the re-pressurization on august 3, 2017, a visual inspection of the door was completed and the trap was brought back up to line pressure and monitored for approximately two hours with no issues. Further investigation determined that there were metal burs on the trap door that damaged the new o-ring during installation. The burs were removed using hand files and sand paper and the o-ring was replaced. Approximately 10 cubic yards of contaminated soil was removed from the release site.
