Narrative
On 10/22/17 at approximately 02:35 local operating personnel discovered crude oil on top of the soil near the n-1 header. All movements were shutdown and remained shutdown until the source could be identified. There are numerous 3rd party delivery points located on this header. At 12:40 operating personnel identified the source of the release to be a compression fitting on the tubing for the sample system. The nrc was immediately notified after confirmed discovery and knowledge of the cost to exceed $50,000. A final report will be submitted once the failure analysis is complete. 5/21/2018 (update): failure analysis states that the leak is attributed to the tubing separating from the coupling underground. The observed mechanical damage to tubing suggests that external mechanical stresses were applied to the tube. It is possible that these stresses loosened the tube, which caused the separation while the tubing was operating.
