Project: Shady Hills Power Company, LLC ( Shady Hills ) is proposing to build two additional, simple cycle combustion turbines (Model: General Electric 7FA.05) (Emissions unit (EU) 005 and 006)

. The GE7FA.05 output is 218 megawatts (MW) (gross) when firing natural gas and 223 MW (gross) when firing ultra low sulfur distillate (ULSD) fuel oil

. The scope of this P revention of

S ignificant D eterioration (PSD) permit is limited to greenhouse gas (GHG) emis sions.

Project Location: The existing Shady Hills Generating Station is located within the City of Spring Hill, in Pasco County, Florida

. The Project will be located within the existing Shady Hills boundaries. The facility has been in operation since 2002 and operates during peak hours of

electrical use.

Authority: The EPA Region 4 is the agency responsible for implementing and enforcing C lean 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 Flori da Department of

Environmental P rotection.Emissions: The maximum potential annual emissions in tons per year (TPY)

from the Project are summarized in the fo llowing table:

Control Technology: Th is PSD permit for the Project requires the use of Best Available Control Technology (BACT) to limit emissions of GHG s , to the greatest extent feasible

.

BACT for this project will include the use of two energy efficient simple cycle combustion turbine s , which will operate primarily

upon lower GHG

- emitting natural gas with limited use of fuel oil as backup . Additional BACT requirements for the emergency

ge nerator, nat ural gas heater

, circuit breakers and fugitives from

on

- site pipeline and natural gas supply will include limitation of

hours of operation for no n

- emergency maintenance and testing

, energy ef ficiency through the regulation of fuel and use of a

cleaner fuel , and work practice standards (for non

- emergency equipment)

.
