Narrative
A pipeline operator discovered product being released from pump #1 on the 102 pipeline. The pump was immediately shut down and upon investigation the operator found a 5/8" stainless steel tubing line was the source of the release. An estimated 100 gallons of natural gasoline was released during the incident. A north wind contributed to product migrating approximately 150' south, crossing the property fence line onto the neighboring tillable farm ground. A third party response contractor was called to assist with the cleanup and the contaminated topsoil was containerized and properly disposed. Frozen ground at the location minimized the impact to any subsurface soil. A metallurgical analysis of the tubing and soil disposal costs are pending. Updated: material analysis indicated that vibration was the cause of the crack in the tubing. The tubing was properly supported and no anomalous vibrations in the pump or motor were recorded. Therefore, this vibration was likely caused by localized turbulence within this seal flush line itself. Vibration measurements will be performed on similar seal flush line installations to determine if this issue exists at other locations.
