| Water hauler inadvertenetly left the load line valve on the water tank open when the tank was emptied on February 12, 2020. Water then froze inside the load line valve and as temperatures warmed up during the day on February 13, 2020, the load line unthawed and water from tank leaked through the open valve and drip pot into the secondary containment structure. It is estimated that approximately 77 bbls of produced water was released inside a lined, metal secondary containment structure. Upon discovery of this incident, the valve was closed and a vac truck was used to recover 100% of the produced water from the lined containment structure. The containment held up good, and there were no impacts outside of the secondary containment structure. The root cause of this incident is human error. TEP production personnel have investigated this incident and has reviewed the proper procedures for unloading tanks with the contractor. |
