There have been no material changes to the environmental matters described in Part I, Item 1, Business —Environmental Matters of the Annual Report, except as described below.

Cleanup of Solid and Hazardous Wastes

Coal Combustion Residuals. In August 2015, TDEC issued an order that includes an iterative process through which TVA and TDEC will investigate, assess, and remediate any unacceptable risks resulting from coal combustion residual (“CCR”) management and disposal at TVA CCR units in the State of Tennessee. As part of this process, TVA has submitted environmental assessment reports (“EARs”) to TDEC, and after the EARs are approved, TVA will submit Corrective Action/Risk Assessment (“CARA”) Plans that will identify the unacceptable risks and TVA's proposed remediation. TDEC will review the CARA Plans and provide comments, and TVA will make revisions to address TDEC's comments until TDEC approves a final CARA Plan for each site. The public also will have an opportunity to review and comment on each CARA Plan prior to TDEC's approval of the final plan. TDEC approved the EAR for Bull Run Fossil Plant ("Bull Run") on November 15, 2024, and TVA submitted the initial draft of the Bull Run CARA Plan to TDEC in January 2025.
