Coal Operations’ Design Change Notice Process
The Tennessee Valley Authority’s (TVA) drawing program is designed and maintained to document the configuration of TVA’s systems, structures, and components. Drawings are utilized for a variety of reasons, including plant operation, maintenance activities, troubleshooting, and to establish clearance boundaries for isolating equipment so that work can be performed safely. Modifications to configuration should be captured through TVA’s Design Change Notice (DCN) process to ensure configuration control is maintained and drawings are updated to reflect the changes.
