On December 13, 2022, the NRC issued a notice of violation and proposed imposition of Civil Penalty of $8,000 (Notice) to St. Vincent’s Medical Center (licensee) for one Severity Level (SL) III problem associated with three related violations. These violations are related to the licensee’s failure to maintain control over a sealed cesium-137 source when, on October 22, 2021, a St. Vincent’s contract employee, without knowledge that the source was being stored in a biohazard waste container, disposed of it along with other waste and failed to conduct a radiological survey of the waste shipment. Specifically, the violations related to this event include the licensee’s failure to (1) dispose of licensed material only by transfer to an authorized recipient, decay in storage, or by release in effluents within the limits as required by Title 10 of the Code of Federal Regulations (10 CFR) 20.2001(a); (2) monitor the surface of by-product material prior to disposal as decay-in-storage waste, as required by 10 CFR 35.92(a)(1); and (3) conduct a semi-annual physical inventory of sealed sources in their possession, as required by 10 CFR 35.67(g). In addition, the Notice included other violations of low safety and security significance that were categorized in accordance with the NRC Enforcement Policy at Severity Level IV.
