Levy Nuclear Plant – Air Emissions

Particulate Drift from Cooling Towers

Emergency Diesel Generators/Pumps

Avoided CO2 Emissions – Over 14 Million Tons per Year vs. Coal Over 6 Million Tons per Year vs. Natural Gas

CO2 Emission Factors – Various Fuels

Nuclear Life-Cycle CO2 Emissions

Annual Air Emissions Comparison

Cooling Water Needs/Supply

Low Profile Closed-Cycle Cooling Towers will be Used – Reduces Cooling Water needs by ~95%

Over 99% of the Project’s Water Needs are for Steam Condenser Cooling Requirements

Cooling Tower Makeup Water Needs are ~122 MGD

Source:

Cross Florida Barge Canal

CT Blowdown of ~82 MGD

Discharge Location:

Crystal River Energy Complex

CFBC at Inglis Lock – Looking West

Freshwater Needs/Source

Project Requires Freshwater for: Process Boiler Water/Steam Makeup

Process Equipment Cooling System

Potable Water for Drinking/Sanitary

Fire Suppression Systems

Freshwater Quantity Needed is 1.58 MGD

Freshwater Source is Groundwater from Floridan Aquifer via Onsite Wells

Groundwater Well Locations/Drawdown

Groundwater Wells/ Wetland Overlay

Wetland Impacts/Mitigation

Project Property Contains a Significant Amount of Wetlands

Project Site Design/Layout Planned to Avoid/Minimize Wetland Impacts

Total Project Impacts (Plant/Transmission) Currently >400 UMAM Credits

Much of the Mitigation Proposed to occur Onsite, with additional Offsite as Needed

Wetlands Total/ Wetlands Impacted

Water Summary

>95% Reduction in Overall Water Needs with the Use of Cooling Towers

>99% of Project Water Needs Met by Use of Salt Water for Steam Condenser

Cooling

Minimal Aquifer and Wetland Impacts from Groundwater Withdrawals

Wetland Impacts Minimized and Unavoidable Impacts Fully Mitigated
