PROJECT LOCATION

The existing Shady Hills’s facility and the project will beare located at the existing Shady Hills 

Generating Station located at 14240 Merchant Energy Way within near the City of Spring Hill, 

in Pasco County, Florida.

PROJECT DESCRIPTION

Shady Hills has applied for a GHG PSD air permit pursuant to the CAA from the EPA Region 4 

for the proposed Project. Shady Hills is proposing to build two additional simple cycle 

combustion turbines (Model: General Electric 7FA.05) at their existing facility. 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 primary fuel will be natural gas with ULSD fuel 

oil, with sulfur content of is 0.015 percent, as backup fuel. The heat input per turbine would be 

2,135 million British thermal units per hour (MMBtu/hour), high heating value (HHV) at 59 deg. 

F, 60 percent relative humidity (ISO conditions). Ancillary equipment consists of a 2.5 MW 

emergency generator (EU 007), a natural gas fuel heater (EU 008), a 2.8 million gallon (Mgal) 

ULSD fuel oil storage tank (EU 009), an SF6 circuit breakers (EU 010), and new on-site natural 

gas pipeline.

Shady Hills’s existing facility consists of three, dual-fuel, 170 MW (nominal) GE PG7241FA 

simple cycle combustion turbine (SCCT)-electrical generators, three 75 feet high exhaust stacks,

and one 2.8 million gallon fuel oil storage tank. The combustion turbine units can operate in 

simple-cycle mode and intermittent duty mode. The units are equipped with dry low-nitrogen 

oxides (NOx) combustors and water injection capability. The three units are regulated under 
SHGS EFS Shady Hills LLC Project (PSD-EPA-R4013) - FinalDraft PSD Permit 1/13/134

Phase II of the Federal Acid Rain Program. The existing facility and the Project are located at 

14240 Merchant Energy Way within near the City of Spring Hill, in Pasco County, Florida. The 

Project will be located within the existing Shady Hills boundaries. The existing facility has been 

in operation since 2002 and operates usually during peak hours of electrical use.

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.

2. If both, EU 005 and 006 are constructed, they shall not operate an average of more than 

3,390 hours per year per CT on a 12-month rolling total basis. No single unit shall 

operate more than 5,000 hours per year on a 12-month rolling total basis, when firing 

natural gas. 

If only one combustion turbines is installed, it shall operate no more than 3,390 hours per 

year on a 12-month rolling total basis, when firing natural gas.

Permittee shall monitor and record the number of hours each CT operates monthly and 

totalled every month for the previous 12 months.

3. If both, EU 005 and 006 are constructed, they shall not operate firingfire ULSD fuel oil

more than 1,000 combined hours per year on a 12-month rolling total. The Permittee shall 

monitor and record the number of hours each CT operates on ULSD monthly and totalled 

every month for the previous 12 months.

If only one SCCT is installed, the CT may operate up to 500 hours firing ULSD oil per

year on a 12-month rolling total. The single combustion turbine may fire additional 250 

hours of ULSD oil, provided that for every hour of ULSD oil fired beyond the 500 hours, 

the CT muist reduce its capability to fire natural gas by five hours (i.e., 5:1 natural gas to 

ULSD fuel oil ratio).

{Example: If the single combustion turbine operates on ULSD fuel oil for 750 hours per

shut down or ceased operation for a period of timeto begin on the minute when fuel is 

first ignited in the CT and terminates on the minute when the CT reaches 50% load.

sufficient to cause temperature, pressure, chemical, or pollution control device 

imbalances, which result in excess emissions above the limits in Condition IX.C.3.

2. Shutdown occurs on the minute when the CT load is less than 50% load until the minute 

that fuel flow to the CT stopsis the cessation of the operation of an emissions unit for any 

purpose.

2.3.Total time (in hours) during startup and shutdown shall be included in the limit on total

d. The type (natural gas or ULSD) and amount of fuel (scf or gals) burned.

e. Ambient conditions (temperature, humidity, and pressure).

7. Permittee shall calculate and record, for each CT, the following on a monthly basis:

a. Monthly average CO2 mass emission rate (lbs CO2/MWh) calculated as the sum 

of each hourly CO2 mass emission rate times the unit operating time for the hour 

divided by the sum of the recorded energy output rates times the unit operation 

time for the hour for all hours of operation in each month. If more than one fuel is

each fuel.

b. Monthly average heat rate (Btu/kWh) calculated as the sum of each hourly heat 

input rate times the unit operating time for the hour divided by the sum of the

recorded energy output rates times the unit operating time for the hour for all 

hours of operation in each month times 1,000. If more than one fuel is utilized in a

month, a separate average heat input rate shall be calculated for each fuel.

the 12 month period based on the total fuel fired during the prior 12 calendar 

months, at all times other than startup and shutdown, using the global warming 

potential (GWP) factors in Condition J: GLOBAL WARMING POTENTIAL 

(GWP).

.

b. The 12-month rolling average heat rate gross output (Btu/MkWh) (for each fuel

combusted in the previous 12 months) shall be calculated based on the total fuel 

fired, at all times other than startup and shutdown, during the prior 12 calendar 

months using the global warming potential (GWP) factors in Condition J. as the

sum of each monthly average heat rate value times the monthly energy output 

(kWh) divided by the sum of the energy output (kWh) generated during the 12 

month period.

c. The 12-month rolling total CO2e emission rate shall be divided by the 12-month 

rolling gross output rate to determine the lb/MWh rolling average.

a.

8. For demonstrating compliance with the limits specified in Condition IX.B.1, Permittee

shall use the procedures set forth in 40 CFR parts 75 and 98 to determine resulting GHG 

emissions (as CO2e) based on the combination of measured CO2 emissions and calculated

consumption during all startup and shutdown events during the prior 12 consecutive 

calendar months divided by the number of startup and shutdown events in the 12-month 

period.

1.2.Permittee shall monitor and record the time, date, fuel type, and duration of each startup 

and shutdown event. These records must be kept for five years following the date of such 

events.

2.3.For demonstrating compliance with the limits specified in Condition IX.C.3, Permittee 

shall use the procedures set forth in 40 CFR parts 75 and 98 to determine resulting GHG 

emissions (as CO2e) based on the combination of measured CO2 emissions and calculated 

CO2e of other GHG pollutants (as specified in Condition J: GLOBAL WARMING 

POTENTIAL (GWP)). Permittee shall keep adequate records of these GHG emission 

calculations according to requirements in Condition IX.H.1.
