Day or daily means calendar day unless otherwise specified in this section.
EGU means electric generating unit.
EPA means the United States Environmental Protection Agency.
Facility means each of the following as defined in this section: Conemaugh; Homer City; Keystone; and Montour.
Facility-wide 30-Day Rolling Average NOXEmission Rate for the Facility shall be expressed in lb/MMBtu and calculated in accordance with the following procedure: first, sum the total pounds of NOX emitted from all Units during the current Operating Day and the previous twenty-nine (29) Operating Days; second, sum the total heat input from all Units in MMBtu during the current Unit Operating Day and the previous twenty-nine (29) Operating Days; and third, divide the total number of pounds of NOX emitted from all Units during the thirty (30) Operating Days by the total heat input during the thirty (30) Operating Days. A new Facility-wide 30-Day Rolling Average NOX Emission Rate shall be calculated for each new Operating Day. Each 30-Day Rolling Average NOX Emission Rate shall include all emissions that occur during all periods within any Operating Day, including, but not limited to, emissions from startup, shutdown, and malfunction.
Fossil fuel means any hydrocarbon fuel, including coal, petroleum coke, petroleum oil, fuel oil, or natural gas.
Homer City means, for purposes of this section, Homer City Generation LP's Homer City Generating Station consisting of three coal-fired units designated as Unit 1 (6,792 MMBtu/hr), Unit 2 (6,792 MMBtu/hr), and Unit 3 (7,260 MMBtu/hr), located in Center Township, Indiana County, Pennsylvania.
Keystone means, for purposes of this section, Keystone Conemaugh Project LLC's Keystone Generating Station consisting of two coal-fired units designated as Unit 1 (8,717 MMBtu/hr) and Unit 2 (8,717 MMBtu/hr), located in Plumcreek Township, Armstrong County, Pennsylvania.
lb/MMBtu means one pound per million British thermal units.
Montour means, for purposes of this section, Talen Energy Corporation's Montour Steam Electric Station consisting of two coal-fired units designated as Unit 1 (7,317 MMBtu/hr) and Unit 2 (7,239 MMBtu/hr), located in Derry Township, Montour County, Pennsylvania.
"NOX " means oxides of nitrogen, measured in accordance with the provisions of this section. "NOXemission rate" means the number of pounds of NOX emitted per million British thermal units of heat input (lb/MMBtu), calculated in accordance with this section.
Operating day means any calendar day on which a Unit fires Fossil Fuel.
Title V Permit means the permit required for major sources pursuant to Subchapter V of the Act, 42 U.S.C. 7661-7661e .
Unit means collectively, the coal pulverizer, stationary equipment that feeds coal to the boiler, the boiler that produces steam for the steam turbine, the steam turbine, the generator, the equipment necessary to operate the generator, steam turbine, and boiler, and all ancillary equipment, including pollution control equipment and systems necessary for production of electricity. An electric steam generating station may be comprised of one or more Units.
Unit-specific daily NOXmass emissions shall be expressed in lb/day and calculated as the sum of total pounds of NOX emitted from the Unit during the Unit Operating Day. Each Unit-specific Daily NOX Mass Emissions shall include all emissions that occur during all periods within any Operating Day, including emissions from startup, shutdown, and malfunction.
