On July 12, 2016, the NRC issued a Notice of Violation and Proposed Imposition of Civil Penalty in the amount of $3,500 to Patriot Engineering and Environmental, Inc., for a Severity Level III violation of 10 CFR 20.1802 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 not in storage and not under the control and constant surveillance of the licensee. Specifically, an authorized user left a gauge unattended and unsecured, and the gauge was run over.
