Current through Register Vol. 30, No. 50, December 13, 2024

Section R9-7-451 - Termination of a Radioactive Material License or a Licensed Activity

A. As the final step before terminating a radioactive material use program licensed under R9-7-312, the licensee shall:

1. Certify to the Department the disposition of all licensed material, including accumulated wastes, by submitting a complete description of a disposal plan with signed receipts from all licensed persons receiving the licensed material; and

2. Conduct a radiation survey of the premises where the licensed activities were carried out to demonstrate that the premises are suitable for release in accordance with the criteria for decommissioning in R9-7-452 and submit to the Department a report of the results of this survey, unless the licensee demonstrates in some other manner acceptable to the Department that the premises are suitable for release in accordance with the criteria for decommissioning in R9-7-452.

B. Before terminating a licensed program, each licensee authorized to possess radioactive material with a half-life greater than 120 days, in any unsealed form, shall forward the following records to the Department:

1. Records of disposal of the licensed material required by R9-7-435, R9-7-436, R9-7-437, and R9-7-438; and

2. Records required by R9-7-418.

C. If a licensed activity is transferred or assigned in accordance with subsection (E), each licensee authorized to possess radioactive material with a half-life greater than 120 days, in any unsealed form, shall transfer the following records to the new licensee and the new licensee shall maintain these records until the license is terminated:

1. Records of disposal of licensed material required by R9-7-435, R9-7-436, R9-7-437, and R9-7-438; and

2. Records required by R9-7-418.

D. Before the Department terminates a license, each licensee shall forward the records required by subsection (E) to the Department.

E. A person licensed under R9-7-312 shall maintain required records regarding decommissioning of a facility in a location identified on the license until the Department releases the site for unrestricted use. Before transfer or assignment of licensed activities, a licensee shall transfer all records required by this Section to the transferee. If records relating to facility decommissioning are kept for other purposes, the transferee shall refer to these records and provide their location on the transferee's application for a license. The transferee shall maintain the records until the Department terminates the transferee's new license. The new licensee shall maintain the following decommissioning records for Department review:

1. Records of spills or other occurrences involving the spread of contamination in and around the facility, equipment, or site. The licensee shall maintain a record of any instance when contamination remains after cleanup procedures or there is a reasonable likelihood that a contaminant has spread to an inaccessible area, as in the case of possible seepage into porous material such as concrete. These records shall include any known information that identifies any radionuclide involved and its quantity, form, and concentration.

2. As-built drawings showing modifications of structures and equipment in restricted areas where radioactive materials are used or stored, and locations of possible inaccessible contamination, such as buried pipes. If as-built drawings are referenced, the licensee need not index each relevant document individually. If drawings are not available, the licensee shall provide records with known information concerning these areas and locations, as prescribed in subsection (E)(1).

3. Except for areas that contain depleted uranium used only for shielding or as penetrators in unused munitions, a list, contained in a single document and updated every two years, of the following:

a. Any area designated or formerly designated as a restricted area as defined under R9-7-102;

b. Any area outside of a restricted area for which documentation is required under subsection (B)(1);

c. Any area outside of a restricted area where wastes have been buried;

d. Any area outside of a restricted area that contains regulated radioactive material that will require the licensee to either decontaminate the area for decommissioning under R9-7-452 or obtain disposal approval under R9-7-435; and

e. Any restricted area where wastes have been buried.

4. Records of the cost estimate performed for the decommissioning funding plan or the amount certified by the Department for decommissioning and the method for assuring funding, if either a funding plan or certification is used.
