Narrative
On july 21, 2017 at 14:50 cdt, a mechanical technician in the vicinity heard something blow out on meter #2 in manifold 154 located in the cushing north terminal. Crude oil started spraying out onto the ground so the mechanical technician quickly opened a drain valve on the strainer in order to relieve pressure and then called the cushing control center. The system was shutdown at this time for scheduled maintenance. Additional steps were taken to stop further release of product and secure the site location included isolating valves and draining the pipe section. It was determined that the leak occurred on meter #2 in manifold 154 at the meter casing welded 90 degree elbow threaded fitting, which is part of the factory meter casing component. Approximately 20 gallons of crude was released. Clean-up was completed on july 24, 2017 and contaminated soil properly disposed of. Ut was conducted on the elbow by an nde technician and the leak cause was confirmed to be due to internal corrosion. Meter #1 was placed into service on july 22, 2017 in place of meter #2 until repairs are completed as directed by marathon (owner of line 51 pipeline). The nrc was notified at 17:01 cdt on july 21, 2017 (#1184838) when it was determined costs could exceed the $50,000 threshold. The nrc follow-up call was made at 8:39 cdt on july 22, 2017 (#1184864).
