On December 11, 2008, a Notice of Violation was issued for a Severity Level III violation. The violation involved the failure to use a minimum of two independent physical controls that form tangible barriers to secure a portable gauge whenever the gauge was not under the control and constant surveillance of the licensee as required in 10 CFR 30.34(i). Specifically, the licensee stored the gauge in a storage room with the key in the door lock rendering the physical barrier ineffective. Additionally, a second independent physical barrier was not provided.
