Narrative
While performing a routine maintenance inspection, company operations personnel discovered a crude oil leak inside nustar's hwy 97 terminal tank farm. The leak originated at the 6 o'clock position of a strainer/filter vessel located upstream of booster pump 404 and within tank 403's containment. Nustar's 70p choke canyon pipeline system was shut down, and both suction and discharge valves were used to isolate the booster pump station. Update - the leak occurred on the bottom head of the strainer at a through-wall internal corrosion pit. The cause of the leak is internal corrosion of the component surface due to microbiologically influenced corrosion.
