On March 14, 2023, the NRC issued a notice of violation (Notice) to Clare County Road Commission (licensee) for a Severity Level (SL) III violation. The SL III violation involved the licensee’s failure to use a minimum of two independent physical controls that form tangible barriers to secure from unauthorized removal or limit access to a Troxler 3430 portable moisture density gauge nominally containing 9 millicuries of cesium-137 and 44 millicuries of americium-241 that was stored in an unrestricted area and not under the control and constant surveillance of the licensee, as required by Title 10 of the Code of Federal Regulations (10 CFR) 20.1801 and 10 CFR 30.34(i). In addition, the Notice included one SL IV violation involving the licensee’s failure to ensure that a hazmat employee received the training required by Title 49 CFR 172.704 at least once every three years.
