Narrative
Two tanks at the terminal were taking an inbound shipment (monitored by magellan operations control in tulsa) with product simultaneously until both roofs were floating. Orders called for tank 427 to be topped, tank 428 to be taken to a specific height and the balance of the shipment to be placed into tank 375. A tank switch was made closing the tank 428 lateral at the tank 400 series manifold by field operators. Upon these valves being secured the local group operations center operator initiated a tank valve closure, mistakenly closing the valve of tank 427 instead of tank 428. The unintended valve closure caused a spike in pressure, opening the pipeline relief valve and creating an abnormal operating condition alarm. The pipeline was shut down and the assets were walked and inspected by station personnel. No failures of equipment were identified at that time and the line was restarted at 16:27 delivering into tank 427 with the corrected lineup. At about 17:10 product was noticed on the ground at the tank 427 valve which is in a vault. Operations control was notified and the inbound pipeline was shut down and the release was isolated. A subsequent investigation determined a gasket on a flange failed. It was determined the initiating event was the incorrect operation but additionally, the flange bolts had not been torqued enough due to the flange utilizing a spec blind spacer. The bolts were torqued according to procedure but the additional smooth face spec blind spacer should have been considered in the torque requirement. The line segment containing the flange was isolated and new flange and gasket was installed. Approximately 53 bbl of product has been recovered to date with the remaining 0.47 bbl to be recovered from impacted soil, resulting in total recovery of the product from the release. It is anticipated that approximately 49 cubic yards of impacted soil will be remediated. Note: this supplemental/final report was filed to correct a typo in the part h initial report.
