On April 17, 2006, a Notice of Violation and Proposed Imposition of Civil Penalty in the amount of $3,250 was issued for a Severity Level III problem involving three violations. The violations occurred as a result of the authorized user?s failure to: (1) control and maintain constant surveillance of a licensed gauge; (2) use two independent physical controls to form a tangible barrier to secure the gauge against unauthorized removal; and (3) properly block and brace the gauge during transport. Specifically, the authorized user failed to adequately lock a transport case onto the bed of his truck and close the tailgate. As a result, the case containing a licensed gauge fell off the truck and was in the public domain for approximately 6 days before it was recovered.
