OBSERVATIONS IN THE EIS The EIS informs TVA’s decisionmakers and meets the environmental review requirements of the National Environmental Policy Act (NEPA). The draft EIS is a programmatic review that broadly assesses the relative impacts of the five strategies on the natural and human environment. The five strategies are the basis for the alternatives discussed in the EIS. Baseline Utility Planning is the No Action Alternative, and the remaining four strategies are the Action Alternatives. The environmentally preferable alternatives are Strategies B and C, which emphasize carbon-free resources and achieve similar CO2 emissions reductions over the planning horizon. These strategies have tradeoffs across other environmental metrics, with higher water consumption in Strategy B and higher land use in Strategy C. It is important to note that TVA will conduct site or project-specific NEPA reviews to consider future generation projects that are proposed to implement the IRP.
Highlights of the draft EIS analysis include:
Climate and Greenhouse Gases
Solid and Hazardous Waste
Water Resources
Land Resources
Overall Observations
Air Quality
Air Quality-free
Land Resources
Overall Observations
Climate and Greenhouse Gases
Water Resources
Solid and Hazardous Waste
Long-term reductions in CO 2 emissions and intensity
Reductions in water use from 2025 to 2050, except in Scenario 5 that has the most nuclear expansion
Increases in land use primarily driven by solar expansion
Coal combustion residuals production drops to zero by 2035
Strategies B and C, which promote carbon-free resources, have the lowest emissions; Strategy C has the lowest water and highest land use
Long-term reductions in air emissions of all types with expected coal retirements
