Narrative
On june 8, 2015 an explorer pipeline personnel identified a small amount of product in a vault that contained the discharge valve of mainline unit 1 at the vinita, oklahoma pump station. Upon further investigation a loose threaded fitting from the bottom side of the blowdown of the valve was identified to be the source of the release. The connection appears to be original construction and records do not reflect any work to the connection or fitting. The pumping unit valve and the station was isolated from the mainline and the threaded blowdown connection to the valve was plugged. Soil sampling indicated that 7.7 gallons of product mixed was released from the threaded connection. Any impacted soil was test and properly managed.
