Decommissioning Plans

DOE O 430.1B, Real Property Asset Management, and its implementation guides require a

project plan for each distinct phase of facility disposition (i.e., Deactivation Plan, S&M Plan, and

Decommissioning Plan) prior to the execution of work. The purpose of these plans is to describe

the work that will be performed and the methods that will be used to accomplish it. An obvious

characteristic of a decommissioning project is that the facility state changes progressively as

work proceeds. For this reason, it is important that the facility state to which a DSA applies is

clearly defined and articulated in the DSA, and that the scope of planned activities is consistent

with the Decommissioning Plan. .

A Decommissioning Plan should define such matters as decommissioning strategy, sequence of

decommissioning tasks and the scope of work at each phase, as these are the key inputs that the

safety analyst needs from the project so that representative analyses can be carried out. It is also

important that the Decommissioning Plan and the DSA be consistent, so any changes to work

plans as defined in the Decommissioning Plan may be considered for potential impacts to the

DSA.

DOE O 430.1B requires that a plan demonstrate how environment, safety and health

requirements are integrated into disposition activities. As also required by DOE P 450.2A,

Identifying, Implementing and Complying with Environment, Safety and Health Requirements,

and 48 CFR 970.5204-78 (DEAR clause on laws, regulations, and DOE directives), information

resulting from planning and hazard identification activities should be used to determine the set of

ES&H directives applicable to the planned facility disposition activity. The list of directives in

Appendix A of this Standard can be used to support this determination. These directives are

organized by hazard type (i.e., hazardous substances and physical hazards) and a "crosscutting"

category that references directives applicable to all missions and hazard types.

The decommissioning plan conveys the set of ES&H requirements that are applicable to a

decommissioning project. This set is not intended to replace or usurp the List A or List B

contractual set of requirements (see DEAR clauses 970.5204-2 and 770.5223-1) that might be

established for a broader contract that encompasses more than just decommissioning. Rather, the

intent is that a Decommissioning Plan conveys the tailored set of ES&H requirements applicable

at the project level, and based on the anticipated hazards and work scope.

2.3

Work Control Process and Task-Level Hazard Analysis

Environmental restoration and decommissioning projects generally consist of multiple work

tasks that must be evaluated throughout the life of the project as specific tasks are planned and

scheduled. The work control process assures that each project task will be conducted in a safe

manner in accordance with all pertinent requirements and controls. Work control activities such

as task-level planning and analysis should be integrated with the Unreviewed Safety Question

(USQ) process to ensure that project tasks are conducted within the safety envelope analyzed by

the DSA. The process for linking work control and the USQ process should be described in the
