Narrative
Approximately 827 bbls of crude oil were released from a transfer line as a result of, what is believed to be, internal corrosion. The failed segment of pipe has been sent to a lab to undergo metallurgical analysis; therefore, a supplemental report will be submitted once the cause is confirmed. The national response center (nrc) was notified and assigned initial report #1176290. A follow-up call to the nrc, assigned report #1176427. Confirmed discovery was initially reported to nrc as 12:32 on 04/21/17 based on a failed pressure test at 12:11 and a call to plains e&rc group from the oklahoma corporation commission (occ). There was an earlier call from the occ to the plains control center at 12:28, which changes the time of confirmed discovery to 12:28 on 04/21/17. Supplemental narrative: based on the metallurgical analysis, the cause of failure has been confirmed to be internal corrosion. The corrosion occurred in a dissolved water and CO2 environment which separated out and collected along the extrados of the bend. Following the release, plains performed a hydrostatic test which incurred no pipe failures. As a result of the release, plains plans to increase the continuous inhibitor injection, change the type of inhibitor used as well as increase the future biocide batch frequency for this system. Part g1 has been updated as a result of this new information. The gps coordinates in part a, number 5 have also been revised. Per a request from PHMSA, part a, 4 of this report was updated to reflect 4/14/17 14:45, which is an estimate based on retrospective analysis. Part e, 1 was updated in order to correspond to this change. The actual time plains became aware of the incident is displayed in part a, 18a.
