Louisiana provided the following information via fax:
Georgia-Pacific (GP), AI#2617, had a shutter that failed open on a Ronan Engineering, Model SA-1-F37, Cs-137 2 Ci. The fixed gauge was located at the GP Consumer Operations LLC's GP Port Hudson facility and reported as not functioning properly. The device is used in production to measure chip level within the Esco Digester. This production unit was currently down for annual maintenance. The handle turned but subsequent surveys could not verify that the shutter was completely closed. As a precaution, GP did not allow any personnel to work in the affected area. [A person] with BP Sales evaluated the device and cycled the shutter to an open position so that the receiver got a positive reading. Therefore, the gauge appears to be functioning properly so that the Esco Digester can restart. The fixed gauge passed previous shutter tests on October 2011 and April 2012. GP plans to replace the gauge within the next 90 days. The gauge is 500 feet above ground and no employees work daily around the gauge.
