Narrative
At approximately 6:15 am cdt on aug 18 while gaugers were performing their rounds, oil sheen was found in the ditch near field boosters (fb) 25 and 26. Gaugers immediately notified superior area management and proceeded to deploy boom in the ditch area. The pipeline maintenance (plm) crews were notified and continued deploying boom in the containment ponds and drainage ditches. Boom was also deployed on the nemadji river as a precaution. It was determined that the source of the oil was the fb25 pump can. The pump had been removed for maintenance june 25, 2014, and after drain up, approximately six inches (2.5 barrels) of oil remained at the bottom of the 28 foot deep can. The drainage system in this area was not able to shed the approximate 3.5 inches of rain water run off received overnight on august 17th. The water backed up, flooded the area and allowed water to enter the pump can from the top, displacing the oil and traveling with the run-off water to two on site containment ponds. In order to alleviate future drainage issues a 16" corrugated culvert has been replaced with a 24" smooth interior plastic culvert, and a rocked swale ditch has replaced an additional 6" culvert. Approximately 175 cubic yards of contaminated soil has been removed from the affected area and disposed of at an approved off site facility.
