Narrative
On 7/17/2020 at 7:45ct, an enterprise technician discovered oil inside a valve vault at cedar pump station. The section of pipe was isolated and a vacuum truck was used to remove free standing oil from the vault. After hydroexcavation, operations determined the oil was coming from the body bleed of an underground 24" valve. At 21:12 ct on 07/18/2020, the nrc was notified due to valve repair costs exceeding $50k. The valve was replaced on 7/24/2020 and the line was returned to service on 7/25/2020. An estimated 25 barrels of crude oil leaked from the valve. Upon investigation, it was determined that the leak was caused by internal corrosion. To prevent reoccurrence, operations and corrosion groups have developed and implemented a flush plan for the facility. Nrc#:1282280 on 07/18/2020, 21:21ct nrc 48hr #:1282366 on 07/20/2020, 11:40ct
