Narrative
On september 16, 2015 a contractor working at the tesoro long beach terminal (lbt) noted vacuum gas oil (vgo) in the secondary containment of the aboveground piping vault. Pipelines running through the vault were idle when the loss of containment was discovered. There were no injuries or impact to the community. It was calculated from average gauges of the oil and water interface within the vault that approximately 70 bbl of vgo leaked from an isolating flange on mov-824 on the t-14 pipeline and was fully contained within secondary containment. It was immediately cleaned up, and the pipeline returned to service at 09:35 on september 18, 2015. A pressure of at least 200 psi was experienced by the t-14 line on september 15, 2015. However, the exact pressure cannot be determined. The monitoring system at lbt was only configured to register pressures up to 200 psi on the t-14 line.
