Notes

(1)  Intensity rates are calculated based on generation from TVA's most recent fiscal year for years indicated and emissions data from the most recent CYs.

(2)  Emissions data is consistent with Edison Electric Institute Environmental, Social, Governance, and Sustainability Report standards, which are based on metric tons ("MTs"), whereas overall CO2 emission rates and baseline reductions from historical levels are based on short tons.

For CY 2024, TVA's emissions of carbon dioxide ("CO2") from its owned and operated units, including purchased power and Renewable Energy Certificate retirement adjustments which reduce the reportable CO2 emissions, were 54 million tons, resulting in a TVA system average, as delivered, CO2 emission rate of 680 lbs/MWh.  This represents a 53 percent and 49 percent reduction in mass carbon emissions and TVA's carbon emission rate, respectively, from 2005 levels.

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 residuals (“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,
