On May 10, 2016, the NRC issued a Notice of Violation to Weaver Consultants Group for a Severity Level III violation of both 10 CFR 20.1801 and 10 CFR 30.34(i). The violation involved the failure to secure licensed material from unauthorized removal or access, with a minimum of two independent physical controls that form tangible barriers, while the portable gauge was stored in a controlled or unrestricted area and not under the control and constant surveillance of the licensee. Specifically, an authorized user left a gauge unattended and unsecured behind his vehicle while searching for additional forms. He later backed up the vehicle and struck the gauge.
