On May 26, 2006, a Notice of Violation and Proposed Imposition of Civil Penalty in the amount of $3,250 was issued for a Severity Level III violation. The violation involved the failure to maintain a minimum of two independent physical controls that formed a tangible barrier to secure a portable gauge from unauthorized removal during a period when the gauge was not under direct control or surveillance. Specifically, the licensee used only one physical control (namely a single chain and lock) to secure the gauge to a vehicle while parked unattended overnight at the South Charleston, West Virginia location. The nuclear gauge was subsequently stolen and abandoned on a public highway.
