Narrative
At approximately 09:30 on 10/27 an enterprise technician discovered a crude oil release while making rounds at the station. Approximately 1 barrel of product had been released from a 1" ball valve near tank 390-34. The tank was in the final steps of an API 653 inspection and repair. Tank had been isolated from common station piping by an 8" valve installed on 10/24 and locked in the closed position. The 8" valve did not seat correctly which allowed product from a common manifold to enter the tank's recirculation system. Correct valve alignment was implemented and API inspection was continued. The crude release was immediately remediated. Employee's oq's were suspended pending re-training, oq's were reinstated on 11/02/2019. After investigation, the recommendation for returning tanks back to service will include conducting walk downs of tank piping prior to reconnection of the tank line to an active station line. Rrc was notified at 10:36 on 10/27/20 nrc was notified at 10:26 on 10/27/20 (nrc# 1262299) nrc 48 hour was given on 10/29/20 (nrc# 1262475)
