Narrative
During pigging of the line from the dock to the tank farm pig got stuck in line for several minutes. Once pig started moving again nitrogen had bypassed the pig. Pig then pushed the nitrogen into the tank. The first tank involved was tank 05 and put about 50 bbls on roof. Switched to tank 03 to receive remaining line displacement and nitrogen push up through the primary and secondary seals and put approximately 2450 bbls on the roof of this tank. The crude oil entered the roof drain and approximately 20 bbls was released. 10 bbls was recovered. 8/22/2012 - enterprise has a detailed job plan and pigging procedures in place at the time of the incident. These procedures were followed correctly, however there was no language in the procedures that specified details of the tank used in the pigging activities. The pigging procedures are being revised to specifiy that empty frac tanks or an empty tank will be used during pigging activties.
