Narrative
At 7:15 am, a truck driver contacted the pipeline operator of a leak at the hanston station. The operator immediately responded and isolated the valve at 8:10. The pump station was shut down five minutes after closing the valve to minimize the spill volume. The failure had occurred at the threads of a 1/2" nipple. The nipple was part of the thermal relief installed around the tank valve. Engineering concluded the failure was fitting fatigue caused by vibration of the piping. The source of the vibration was the mainline positive displacement pump located approximately 200 ft from the tank. The 8 inch pipe between the pumps and the tank is buried. The nipple that broke is a standard threaded steel nipple which was part of the thermal relief around the tank suction valve. The nipple was included in the station piping hydrotest on january 6, 2015 having a minimum test pressure of 431 psi. Upon investigating, the pipe support had settled and was not adequately supporting the 8 in pipe. Engineering conducted a geotechnical study with soil analysis to determine a different type of pipe support should be considered. A helical piling support will be drilled at an estimated 52 ft to adequate soil type to support the piping. Operations are evaluating installation of pulsation dampeners at pd pumps on both the suction and discharge sides of the pumps at all other facilities. Operations is researching coorstek who specialize in pulsation dampeners which can be serviced more efficiently.. Hazmat response remediated the spill and no soil was removed. Kdhe visited the spill location and allowed in place land farm remediation. Acme provide the report of soil remediation.
