Narrative
On 06/06/2016 company personnel arrived at blum station at approximately 07:00 and discovered crude oil in the containment area. The control center was immediately notified and the mainline was sht down. Emergency response personnel were activated and dispatched to the site. Approximately 200 barrels were released to the containment area and facility retention pond. Investigation revealed a pinhole in a 4" drain line from the bottom of the strainer basket to the sump. The affected piping was removed and associated piping/appurtenances were blinded. The failed pipe was sent for metallurgical analysis and it was determined that the cause was microbial induced, internal corrosion. New strainer piping installed will have an internal liner to prevent recurrence of internal corrosion and future releases.
