Project: Tampa Electric Company (TECO) is proposing a major modification 

which will result in modernizing the existing Polk Power Station 

(PPS) by using higher-efficiency, lower-emission, combined cycle 

technology (Project). This Prevention of Significant Deterioration 

(PSD) permit includes the modification of four existing simple cycle 

combustion turbines to add combined cycle operation in a 4-on-1 

configuration. Natural gas will be the primary fuel source with ultralow sulfur diesel fuel oil as backup. The scope of this PSD permit is 

limited to greenhouse gas (GHG) emissions.

Project Location: The existing PPS facility is located approximately 13 miles 

southwest of the city of Bartow, in Polk County, Florida. The 

existing PPS site is situated within approximately 2,837 acres of land 

owned by TECO. The Project will be located within the existing PPS

boundaries.

Authority: The EPA Region 4 is the agency responsible for implementing and 

enforcing Clean Air Act requirements for GHG sources in Florida. 

Sources are required to obtain an air quality permit before beginning 

construction. The draft permit incorporates the applicable 

requirements for GHG emissions from the federal PSD program. A 

separate permitting action addressing other pollutants is under the 

jurisdiction of the Florida Department of Environmental Protection.
Emissions: The maximum potential annual emissions in tons per year (TPY) 

from the Project are summarized in the following table:

Control Technology: This PSD permit for the Project requires the use of Best Available 

Control Technology (BACT) to limit emissions of GHGs, to the 

greatest extent feasible. 

BACT for this project will include the use of an energy efficient 

4-on-1 combined cycle configuration, which will rely primarily upon 

lower GHG-emitting natural gas and limited use of fuel oil as 

backup, and limited simple cycle operation. BACT requirements for 

the emergency generator will include work practice standards to 

ensure proper operation and maintenance. BACT for the circuit 

breakers (to control SF6 emissions) is the use of modern enclosed 

systems with low-pressure alarms and periodic inspection.

Additional Information: The draft permit and preliminary determination document that 

explains the derivation of the permit conditions are available on the 

EPA Region 4’s website at:
