Narrative
On october 10th, 2017, a contractor working for plains all american pipeline (plains) was performing final grading of the right-of-way following backfill of the plains-centurion pipeline crossing site. The contracting company equipment operator, who was not authorized to perform any excavation at the site, struck the centurion's 16'' slaughter to cushing system #2 pipeline with a bulldozer. The subsequent pipeline strike punctured the line causing a loss onto the right-of-way approximately 377 barrels of crude oil. Approximately 164 barrels of crude oil were unrecovered, requiring soil remediation. Currently, the contaminated soil has been removed from the incident site and remediation efforts are ongoing. With remediation efforts still in progress, the reported cost estimates reflect the current total but may change after this report is filed. Any significant changes to the cost estimate will be reported in a supplemental report. Nrc report number 1192883 corresponds to the initial telephonic report for this accident, and nrc report number 1193089 corresponds to the 48 hour update report. The centurion pipeline was clearly and properly marked by qualified centurion personnel, and the contract excavation personnel were aware of the location of the line. All centurion policies and procedures were followed. The pipeline was placed back into service at 2:40 pm on october 12th, 2017. There were no associated injuries or fatalities. No oil reached a waterway and environmental remediation is anticipated to be successful. January 15, 2018: centurion pipeline, l.P. Is filing an additional supplemental and final report at PHMSA's request to change question a.4 to 16:40.
