On May 22, 2007, a Notice of Violation (NOV) and Proposed Imposition of Civil Penalty in the amount of $9,750 was issued for a Severity Level III violation involving the failure to secure licensed material from unauthorized removal resulting in the loss of a portable nuclear density gauge. The gauge was missing for approximately 5-months before it was found in the public domain in Philadelphia, Pennsylvania. A second NOV involved the failure to immediately report the loss of the licensed material to the NRC.
