On july 22, 2021 at approximately 7:15 am pt, a marathon terminal 2 operator performing a routine facility inspection identified an active leak on an 8" appurtenance (nozzle) to tank 221. Tank 221 is an oily water tank inside of the tank farm of the marine terminal. The operator alerted company personnel and emergency activities were initiated immediately. Tank 221 was static at the time the leak was discovered, but operating systems (including pressure reliefs) tied to the tank were shutdown at approximately 7:30am. A temporary repair was implemented at approximately 8:00am on july 22, but the tank remained out of service to allow for a permanent repair to be coordinated and implemented. Impacted pipeline systems were restarted at 9:30am on july 22 once alternative operational plans were implemented. Tank 221 was then drained of liquid down to a level of 3.5 feet and a permanent repair was implemented on july 25, 2021 at 5pm. The tank was refilled and recommissioned the evening of july 26.
