On July 9, 2008, a Notice of Violation was issued to McKinney and Company. This action is based on a Severity Level III violation of 10 CFR 30.34(i) involving the licensee's failure to maintain a minimum of two independent physical controls that formed tangible barriers to secure a portable gauge from unauthorized removal during a period when the portable gauge was not under the control and constant surveillance of the licensee. Specifically, five portable gauges were found unattended inside an unlocked building with only one physical control (a locked storage area door) that formed a tangible barrier to secure the portable gauges.
