ACTION: Preliminary Determination and Draft Greenhouse Gas Air 

Permit, PSD-EPA-R4013, for Shady Hills Power Company, 

LLC, Shady Hills Generating Station

Public Notice & September 24 to October 24, 2013, 2013; Public Hearing

Comment Period requests must be received by October 8, 2013.

Publication in The Tampa Tribune.

Public hearing: October 24, 2013, 3:00 pm until 7:00 pm

(if significant public Regency Park Library

interest) 9701 Little Road, Port Richey, FL 34654

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 Prevention of 

Significant Deterioration (PSD) permit is limited to greenhouse gas 

(GHG) emissions.

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 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 two energy efficient 

simple cycle combustion turbines, which will operate primarily 

upon lower GHG-emitting natural gas with limited use of fuel oil 

as backup. Additional BACT requirements for the emergency 

generator, natural gas heater, circuit breakers and fugitives from 

on-site pipeline and natural gas supply will include limitation of 

hours of operation for non-emergency maintenance and testing, 

energy efficiency through the regulation of fuel and use of a 

cleaner fuel, and work practice standards (for non-emergency 

equipment).
