Narrative
On 07-09-2017 at approximately 07:00 enterprise operations was notified of crude oil on the ground inside of valero's facility. Operating personnel were dispatched to the area to start the investigation into the source. Enterprise has a delivery skid located inside valero's facility which was not making a movement at the time of discovery. In the area that the crude was discovered valero has many facility lines that run to and from different points within their facility. At approximately 1100 hours on the 9th it was determined that the source of the leak was on an enterprise asset and not valero. At that time the nrc notification was immediately made resulting in report number 1183549. The 48 hr update was completed on 07-10-17 resulting in report number 1183669. A c-scan of the piping was conducted to determine if internal corrosion was the cause of the release. After reviewing the results of the scan, internal corrosion was ruled out due to the fact that there were no indications of wall loss other than the pinhole. A visual examination of the piping also ruled out external corrosion. A type b sleeve was approved and welded onto the pipe as the permanent repair. Update (9/28/2018): no deliveries were being made at the time of the leak and there was no interruption of service to customers. Pressure at the time of the leak was approximately 2 psi.
