Narrative
A crew inspecting the tank area identified a small amount of crude oil (estimated at 2-3 gallons) on the concrete ring wall of tank 9. Tank 9 was isolated and product removed. The keystone pipeline system has a scada system and cpm leak detection system. All tanks at the cushing tank terminal including tank 9 have a leak detection system in accordance with API 650. Clean-up, product recovery, and value of lost product was expected to exceed the reporting threshold of $50,000.00 as defined in part 195.52 by october 23, 2018. There was no impact to water. A root cause failure analysis has been initiated. 26 april 2019 update: the root cause failure analysis and metallurgical report have been received and submitted to PHMSA aid. Repairs to the tank have been completed under warranty and the tank is operational. 6 may 2019 update: the primary cause of the leak was a complete lack of fusion defect in a full fillet of a tank bottom lap joint that occurred when the mechanized welder travelled off track.
