Narrative
On november 28, 2017 at approximately 12:40 est, sheen was observed on pooled water in the excavation site for an integrity dig on line 5 at mp 1549.67. The pipeline was immediately shutdown as a precaution. The excavation area was evacuated and plm and environmental support crews were dispatched to investigate. Investigation concluded that the sheen was a petroleum product. Nde was ordered and executed on november 29, 2017. At 11:30 est, the determination was made that a through-wall feature existed at a girth weld in the excavation which correlated the sheen with the pipeline. The nrc was notified (report # 1198339) due to the potential costs exceeding reportable thresholds. A sleeve was installed and the site was restored. Line 5 was restarted at 23:26 est on november 29, 2017. The actual volume released at mp 1549.67 was 0.0001 barrels. The PHMSA portal does not recognize volumes less than 0.01 barrels therefore that is the volume entered.
