Shady Hills Generating Station Air Permit PSD-EPA-R4013

For Shady Hills Power Company, LLC

Public Comment Period: September 24, 2013 to October 24, 2013

The U.S. Environmental Protection Agency is seeking public comment on a draft Clean Air Act

(CAA) Prevention of Significant Deterioration (PSD) Greenhouse Gas (GHG) air permit for 

Shady Hills Power Company, LLC (Shady Hills) Shady Hills Generating Station Project (SHGS 

or Project), 14240 Merchant Energy Way within the City of Spring Hill, in Pasco County, 

Florida. The draft permit will regulate GHG emissions from two additional simple cycle turbines 

(Model: GE 7FA.05). The GE 7FA.05 output is 218 megawatts (MW) (gross) when firing 

natural gas and 223 MW (gross) when firing ultra-low sulfur diesel (ULSD) fuel oil. Ancillary 

equipment consists of a 2.5 MW emergency generator, a natural gas fuel heater, a 2.8 million 

gallon ULSD fuel oil storage tank, an SF6 circuit breaker, and new on-site natural gas pipeline.

The EPA Region 4 is the agency responsible for implementing and enforcing CAA requirements 

for GHG sources in Florida. Pursuant to the air quality regulations applicable to GHG sources set 

forth in Title 40, Code of Federal Regulations (CFR), Part 52, a GHG source is required to obtain 

an air quality permit before beginning construction. The EPA has completed review of Shady 

Hills Generating Station’s air permit application and supplemental materials and is soliciting 

comments on the Agency’s proposal to issue Permit No. PSD-EPA-R4013 to Shady Hills for 

their project, which is subject to the terms and conditions described in the permit.

The EPA has prepared a draft permit for public comment, as well as a preliminary 

determination/statement of basis document that explains the basis of the permit conditions. 

These documents are available on the EPA Region 4’s website at: 

http://www.epa.gov/region4/air/permits/ghgpermits/ghgpermits.html. To request a copy of these 

documents or to be added to the EPA’s GHG permit mailing list, please contact: Ms. Rosa 

Yarbrough, Permit Support Specialist at: 404-562-9643, or yarbrough.rosa@epa.gov. For

Project Emissions: The maximum potential annual emissions in tons per year (TPY) of GHG 

emissions from Shady Hills are summarized in the following table. Shady Hills is an existing

major source and this project triggered PSD review for emissions of GHGs exceed the subjectto-regulation applicability threshold of 75,000 TPY of carbon dioxide equivalent (CO2e) and the 

PSD significant emission rate of 0 TPY of GHG emissions on a mass basis. Hence, Shady Hills

is required to apply Best Available Control Technology for GHGs.

jurisdiction of the Florida Department of Environmental Protection.
