Narrative
At 13:04 central time on 10/21/2019, a third party called about a crude oil leak at enterprise's pasadena delivery station. An enterprise technician responded to the site at 13:52 central time and found crude oil bubbling through rock above an 8" pig trap kicker line. The line was immediately isolated and shutdown. The leaking pipe was removed and associated connections blind flanged. It is estimated that 40 barrels were released. Metallurgical analysis of the failed pipe determined the cause as internal corrosion. To prevent recurrence, a flushing plan will be implemented once the kicker line is reinstalled. Flushing will occur during maintenance pigging. The nrc#1261798 call was made 10/21/2019 at 19:05 central time due to repair costs being determined to exceed $50k. The nrc#1261997 48-hour update call was made 10/23/2019 at 16:56 central time.
