Narrative
On tuesday, june 12, 2018, at approximately 10:17, a boring machine operated by k & b directional, inc., a sub-contractor working for watkins construction llc at the behest of energy transfer partners, struck the centurion pipeline, l.P. (cpl) braden to midkiff 8'' pipeline near midkiff, texas, resulting in the loss of containment of approximately 130 barrels of crude oil. The crude oil filled the boring excavation where 110 barrels were recovered by vacuum trucks, and the remaining 20 barrels were recovered by soil remediation. Cpl repaired the pipeline and returned it to service at 02:36 on june 15, 2018. No injuries or fatalities were associated with this accident, and soil remediation is complete. Upon company personnel arriving onsite at 10:40 on june 12, 2018, it was determined that an excess of 5 barrels of crude oil was released. It was not determined to be cpl's pipeline until excavation was sufficiently completed at 13:02 to ascertain that among the flow lines and unmarked pipelines in the immediate vicinity it was cpl's line that was struck. Pursuant to this confirmation the national response center (nrc) was called at 13:25. The nrc report number 1215060 corresponds to the initial telephonic report for this accident, and nrc report number 1215261 corresponds to the 48 hour update report. Texas railroad commission job number 134998 corresponds to this accident. Cpl correctly marked the 8'' pipeline in accordance with one call procedures. However, prior to the boring activity, the contractor incorrectly identified a 3'' steel flow line as the braden to midkiff 8'' pipeline during pot-holing. The contractor attempted to bore under the misidentified pipeline and struck the marked braden to midkiff pipeline in the 3 o' clock position at a depth of 7'10'' resulting in the aforementioned release. Supplemental final report filed on august 1, 2018: in response to PHMSA's suggested changes, cpl updated a4 from 10:40 am to 10:17 am to reflect the earliest known time that a reporting criteria may have been met. Cpl updated a7 from 13:25 to 13:48 to correspond with the correct time of the call to the nrc. Cpl also changed a9 from 130 barrels to 890 barrels to include the volume of crude oil drained from the braden to midkiff pipeline prior to repairs being made. Phmsa requested the costs in d8 be validated. Upon further review, cpl updated the costs to include the invoices received since the original report filing. Overall, the total costs to the operator increased from $55,320 to $61,610. Phmsa also requested the pressure at the point and time of the accident, reported in e1, to be validated, given that the line pressures are only measured at braden station and midkiff station, and that there are no flow at the time of the accident., cpl estimated the head pressure at the point and time of the accident and updated e1 from 31 psig to 2.42 psig. Upon further review of the length of the segment isolated as result of the third party line strike, cpl updated e5c from 36,876 feet to 46,992 feet to account for the entire length of the braden to midkiff 8'' pipeline. Cpl updated e9 to include the results of the control room evaluation, which confirmed that no control room or controller issues were identified.
