Title	Agreement State Report - Stuck Shutter on Fixed Industrial Gauge
Event Description	The following was received from the State of Oklahoma via email: Phillips 66 Co. (OK-07402-12) has reported the failure of the shutter mechanism on one of their fixed gauges. Earlier today the shutter was closed while the licensee collected a leak test sample. The RSO noted that the shutter was difficult to operate. When they returned the shutter handle to the 'open' position, the control room which monitors the gauge readings reported that the readout briefly returned to its normal level, then dropped back to zero when the shutter was supposed to be fully open. Repeated attempts showed that the gauge only operated when the shutter was approximately 75% of the fully 'open' position. The licensee has contacted the gauge manufacturer but they won't be able to supply a replacement for approximately 6 weeks. The licensee has requested permission to leave the gauge in service until a replacement is available. The gauge is installed on a stand pipe 18 feet above ground level in an oil refinery in Ponca City, OK. It is only accessible by catwalk which the RSO is going to cordon off. Material in the gauge is Cs-137, 25 mCi when new in 1993. We[State of OK] have told the RSO they may leave the gauge in operation pending the results of the leak test. If these show the source to be leaking they must immediately remove the gauge from service.
