On February 1, 2016, the NRC issued a Notice of Violation to Ferrovial Agroman, S.A, for a Severity Level III violation. The violation involved a failure to control and maintain constant surveillance or failure to use two independent physical controls that form tangible barriers to secure a portable gauge from unauthorized removal as required by 10 CFR 20.1802 and 30.34(i). Specifically, on April 28, 2015, a gauge containing licensed material was left unattended and uncontrolled in the back of a pickup truck at a temporary jobsite and was secured to the truck with two independent controls. However, the keys to both the vehicle and the gauge locks were left in the unlocked truck, which was stolen from the jobsite.
