Narrative
During a weekend aerial patrol by a third-party pipeline company, a crude oil leak was discovered at nustar's dixon terminal, north of borger, texas. Upon investigation, the leak was discovered originating from underneath nustar's tank d3. The crude oil in tank d3 was evacuated. The leak originated at a through-plate corrosion feature on the tank floor. A section of the floor containing the feature has been removed for examination. Update - the cause of failure was microbiologically induced corrosion, and a failure of the tank's internal liner contributed to the corrosion at the location of the leak.
