Current through Register Vol. 30, No. 38, September 20, 2024
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.
