Narrative
On july 16, 2015, a spectra energy employee detected a petroleum crude oil odor at the platte pipe line casper station and conducted a station check to determine the source of the odor. During the station check the employee discovered a petroleum crude oil release in the tank manifold area. Upon discovery of the release, the employee contacted the control center and the pipeline was shutdown and the tank manifold area was isolated. A preliminary determination indicates the source of the release was a "dead leg" in the tank manifold area that was not connected to the main line. Initial assessments indicate the leak may have been caused by microbiologically-influenced corrosion (mic) due to the static state of the dead leg; however, an internal investigation team has been created to determine the root cause of the release. The dead leg has been isolated and will be removed and submitted for analysis as part of the investigation. As soon as it was determined the release met accident reporting criteria it was promptly reported to the nrc (report numbers: 1122929 and 1124740), wdeq (report number: 150716-0958), and the lepc. All released product was contained within the facility boundary and there were no injuries, no fire/explosions, no impacts to water, and no impacts to wildlife. Free liquids were recovered via vac trucks and mechanical equipment was used to remove petroleum contaminated soils. All excavated soil was stockpiled on top of visqueen within a bermed area at the facility and spectra energy is consulting with wyoming deq to determine the best disposal/treatment option.
