Title	Agreement State Report - Fixed Gauge Shutter Would Not Close Properly
Event Description	The following information was received via fax: On 03/17/2015, the RSO for MOTIVA ENTERPRISES called in a preliminary report about a shutter that would not close properly on a gauge installed on a process. The shutter could not be closed or locked out. This situation reoccurs periodically due to the corrosive operating environment of this gauge or device. Routine maintenance was performed by BBP Sales and the device again functioned as designed. This situation is reoccurring about every 11 to 14 months. The corrosive and caloric operating environment is the source of this operational problem. The problem with the shutter function is corrected by cleaning and lubricating the mechanism. The equipment/source holder is not broken, just in need of preventive maintenance. There was no removable radiation detected in the leak test results and the rotor moved freely when the top plate was removed for the maintenance. BBP Sales was called to perform the maintenance to correct the problem. The gauge/source holder was 'fixed.' The repairman/technician was never exposed to a radiation field greater than 3.0 mR/hr. The Department [Louisiana Department of Environmental Quality] considers this item closed and the records will be reviewed during the next inspection. Gauge is an Ohmart Vega S/N 3211CO with a 175 Ci Cs-137 source. Louisiana Report: LA 15-0006, T162348
