At 2:43 pm cst enbridge personnel arrived at the dig site and confirmed the potential release, but was unable to provide an estimate of oil released. The nrc was notified at 2:45 pm cst on november 28, 2018 (nrc# 1231534). At 3:42 pm cst it was initially estimated that one barrel of oil was released with the amount of free oil of one pint. After excavation of the contaminated soil that measured 36' long by 4' deep by 3' wide it was calculated that 1.5 barrels of oil was released. The 48 hour update was provided to the nrc at 4:58 pm cst on november 29, 2018 (nrc#1231647). Upon investigation, the cause of the failure was determined to be a through wall crack in the long seam.

Approximately 34 tons of contaminated soil has been properly disposed of at an approved landfill.
