Section I: Premises Information/DescriptionA. PREMISES INFORMATIONNature of Business:Electric Generation for Wholesale SalePrimary SIC:4911Facility Mailing Address:PSEG Power Connecticut, LLC1 Atlantic StreetBridgeport, CT 06604Telephone Number:Mr. Vincent Fiumidinisi, 203-551-6001B. PREMISES DESCRIPTIONThe Bridgeport Harbor Station (BHS) is an exempt wholesale electric generating facility, owned andoperated by PSEG Power Connecticut LLC (PSEG) with its principal place of business in Newark, NewJersey.Electricity is generated at the facility through a various types of equipment as follows:EU-3: Combustion Engineering Steam Generator (Unit No. 3) 400 MW (megawatts), a tangentially fireddual-fuel unit (low sulfur coal and fuel oil) equipped with an in-line heater (No. 2 fuel oil fired) thatremoves excess moisture from coal prior to combustion. The steam generator has the following controlequipment: a low nitrogen oxides (NOx) concentric firing system to control NOx emissions, a baghousewith an activated carbon and dry sorbent injection systems used only during coal combustion to controlmercury (Hg) and acid gas emissions, respectively, and an electrostatic precipitator (ESP) to controlparticulate matter (PM) emissions.EU-4: Pratt & Whitney Gas Turbine Generator (Unit No. 4), a simple cycle turbine burns aviation fuel orequivalent and is used during peak energy demand periods. The facility also operates Cummins ModelH61P Diesel Fire Pump Engine (EU-6) near Unit No. 4 for the existing fire suppression system.A combined cycle unit (Unit No. 5) that is a single combustion turbine generator exhausting to a singlesupplementary fired Heat Recovery Steam Generator (HRSG). Steam generation in the HRSG drives asingle steam turbine generator. The combined cycle consists of the following:EU-50: General Electric Dual Fired Combustion Turbine that fires natural gas and ultra-low sulfurdistillate (ULSD) fuel, a duct burner that fires natural gas and a HRSG. Emissions are controlled bydry low-NOx combustors, water injection (when the turbine is firing ULSD), a selective catalyticreduction (SCR) system, and an oxidation catalyst system. The turbine has a Cummins emergencyfire pump engine (EU-53) that fires diesel fuel. The emergency fire pump engine provides backupmechanical energy to the fire suppression system for the Unit No. 5 project. A SPX AuxiliaryCooling Tower (EU-54), fire pump engine and separate, small emission units (GEU-1) consisting of:building space heaters, makeup air heaters, and heating ventilating and air conditioning (HVAC) areancillary pieces of equipment associated with it.EU-51: Victory Energy boiler that fires natural gas and is equipped with ultra-low NOx burners andFlue Gas Recirculation (FGR). The boiler produces auxiliary steam to provide certain heatingfunctions prior to and during startups in order to allow shorter startup time durations.PSEG Power Connecticut, LLC, BHSPage 7 of 154Permit No. 015-0217-TV

Section I: Premises Information/DescriptionEU-52: Caterpillar emergency generator that fires diesel fuel. The emergency generator providesemergency back-up power to the combined cycle unit. The emergency generator is not connected tothe electrical grid.Additional support equipment includes several storage tanks.PSEG is a Title V source because actual sulfur oxides (SOx), NOx, carbon monoxide (CO) andgreenhouse gas (GHG) emissions exceed the major source thresholds. Also PSEG is a Title V source asdefined in RCSA §§22a-174-33(a)(10)(A) and (B) (subject to 40 CFR Parts 60 and 63), RCSA §22a-17433(a)(10)(C) (subject to 40 CFR Parts 72-78) and RCSA §22a-174-33(a)(10)(F) (location of one or moremajor sources). PSEG is located in a severe ozone non-attainment area as defined in RCSA §22a-1741(104).PSEG is subject to the following:TAO No. 8367Trading Agreement and Order for EU-3 (Steam generator)TAO No. 8368Trading Agreement and Order for EU-4 (Turbine generator)40 CFR Part 60 Subpart DcStandards of Performance for Small Industrial, Commercial,Institutional Steam Generating Units40 CFR Part 60 Subpart IIIIStandards of Performance for Stationary Spark Ignition InternalCombustion Engines40 CFR Part 60 Subpart KKKKStandards of Performance for Stationary Combustion Turbines40 CFR Part 63 Subpart DDDDDNational Emission Standards for Industrial, Commercial andInstitutional Boilers and Process Heaters-Major Sources40 CFR Part 63 Subpart YYYYNational Emission Standards for Hazardous Air Pollutants forStationary Combustion Turbines40 CFR Part 63 Subpart ZZZZNational Emission Standards for Reciprocating InternalCombustion Engines (RICE)40 CFR Part 63 Subpart UUUUUNational Emission Standards for Utility NESHAP40 CFR Parts 72-78Acid Rain Requirements40 CFR Part 96 Subpart AAAAClear Air Interstate Rule (CAIR)PSEG Power Connecticut, LLC, BHSPage 8 of 154Permit No. 015-0217-TV
