We determined TVA generally managed designated outage materials to maximize use and minimize cost. Specifically, we found (1) no instances where TVA missed material redeployment opportunities for designated outage materials and (2) all outage items designated for surplus and subsequently repurchased were warranted.

TVA management remediated or mitigated all identified vulnerabilities and agreed with our remaining findings and recommendations.
