Narrative
At approximately 13:30 on may 4, 2017 operator personnel were performing a station check during commissioning process of the etco pipeline. A release of approximately 1/2 barrel was discovered due to apparent body failure of two 4 inch ball valves. Both valves were closed and the release stopped from one but the other continued to weep. The segment of pipe was isolated, the release contained and the valves removed and replaced. Contaminated soil was removed for proper disposal. Upon examination it was determined that residual water likely from hydrostatic pressure testing of the pipeline remained entrapped in the valves and freezing temperatures caused expansion inside the valve leading to the body failure.
