Narrative
On april 23 at approximately 3:00 pm, while conducting the daily inspection at the viking station, the technician noticed oil on the ground in and around the whistle in the area of the line 2 discharge pressure transmitter. Line 2 was immediately shut down to determine the source of the oil. The threaded joint between the 2"piping and the 2" valve off the mainline failed. Further investigation discovered the leak was caused by the whistle frost heaving up and pushing on the 2" pipe, which in turn caused the pipe threads to fail. A temporary hose was installed that same day and line 2 was returned to service later that evening. The permanent piping is being configured and will be put into service in the next few weeks. Approximately 220 yards of contaminated soil was removed from the site and disposed of at an approved location.
