Narrative
An enbridge employee notified enterprise of a leak on the 8-inch crude line located on enbridge property. The line was immediately shutdown and cleanup actions implemented. Sunoco was in the process of delivering 43,700 barrels of crude oil to the cushing east facility when the release was discovered. A hydroexcavator was used to expose the pipeline and locate the source of the leak. A temporary clamp was installed to ensure no additional product was leaked and until a plidco clamp could be located and installed. The delivery resumed after the plidco clamp was installed with pumping restricted to daylight operations only. The recommendation is that the existing delivery line from the sunoco meter bank to the leak site be pigged, purged, filled with nitrogen and abandoned in place; isolating the line to the west facility fabricate and install a new, above ground 8-inch line from the sunoco meter bank to the sunoco delivery manifold that supplies the enterprise east facility. All future sunoco deliveries will be received into the cushing east facility.
