During decommissioning, which records or clearance are required before completing the process?

• A. No records required.
• B. Only the waste manifest.
• C. Finalized records and regulatory clearance.
• D. Inventory list only.

Answer: (C)

Finalized records and regulatory clearance are needed to close out decommissioning because there must be an auditable proof that the site has been cleaned up and meets the required release criteria, and that a competent authority has formally approved the release. The records capture the final status survey, waste disposition, decontamination and any remediation actions, inventories, and other documentation showing the facility now meets the conditions for release. Regulatory clearance is the official permission from the regulator confirming that the site complies with applicable limits and can be released for its intended future use. Without both the complete, finalized records and the regulator’s authorization, the decommissioning cannot be considered complete, even if all waste is removed, as there is no formal proof of compliance or official release. The other options lack either the formal authorization or a complete, verifiable trail necessary to demonstrate proper closure.
