Appendix C
Closure Planning and Implementation
Table C-1 lists activities that are likely relevant to closure of any industrial or government facility. Not all of the activities are necessarily applicable to a particular closure situation. The indented items in the table are primarily illustrative and are not intended to be all inclusive, but rather to indicate the types of activities required at those stages of the closure process under which they appear.
The planning phase consists of (1) an assessment and decision-making period in which general overall objectives and criteria are formulated and (2) a closure plan development period when plans are formulated and written. In practice, there can be considerable overlap between assessment and decision making as a detailed plan is developed.
The implementation phase can be viewed as a period of actual closure operations, followed by facility closeout (postmortem). Here, too, there may be some overlap of the two activities. Finally, the facility site may undergo postclosure activities in accordance with agreed-upon regulatory requirements.
