(d)Effect of incorporation of 10 CFR 20.1403"Criteria for license termination under restricted conditions."(1) The commissioner shall not terminate a license under restricted conditions as provided for in 10 CFR 20.1403 until the decommissioning plan required by 10 CFR 20.1403(d) is approved by the commissioner and has been in effect for a period of time demonstrating to the commissioner that continued implementation of the plan will be effective in maintaining compliance with the required conditions of the plan.(2) The commissioner may choose to implement the license termination process in one or more of the following steps: (A) The license is amended to authorize activities necessary to begin decommissioning under the decommissioning plan;(B) After decommissioning activities are complete and the provisions of 10 CFR 20.1403 are in effect under the decommissioning plan, the license may be amended to end authorization of licensed activities. The license shall remain in effect for up to five (5) years; and(C) At the end of the period prescribed in subdivision (1) of this subsection, the commissioner shall decide the effectiveness of the established decommissioning plan.
