Alabama Administrative Code › Title 335 - ALABAMA DEPARTMENT OF ENVIRONMENTAL MANAGEMENT › AIR DIVISION - AIR POLLUTION CONTROL PROGRAM › Chapter 335-3-8 - NITROGEN OXIDES EMISSIONS › Section 335-3-8-.04 - NOx Emission Standards For Stationary Reciprocating Internal Combustion Engines

Current through Register Vol. 42, No. 9, June 28, 2024
(1)
				Applicability. The requirements of this Rule apply to any person that owns or
				operates a facility at which one or more large affected engines were located
				during the baseline period.
(2)
				Definitions. For the purpose of this Rule, the following definitions apply:
(a) "Affected engine" means an engine that
				was operated within the fine grid during the baseline period and was included
				in the NOX SIP Call Inventory.
(b)
				"Control period" means the period beginning May 1 of a year and ending on
				September 30 of the same year, inclusive, beginning in 2007.
(c) "Fine grid portion of the State" or "fine
				grid" means the geographic area that includes the Counties of Autauga, Bibb,
				Blount, Calhoun, Chambers, Cherokee, Chilton, Clay, Cleburne, Colbert, Coosa,
				Cullman, Dallas, De Kalb, Elmore, Etowah, Fayette, Franklin, Greene, Hale,
				Jackson, Jefferson, Lamar, Lauderdale, Lawrence, Lee, Limestone, Macon,
				Madison, Marion, Marshall, Morgan, Perry, Pickens, Randolph, Russell, St.
				Clair, Shelby, Sumter, Talladega, Tallapoosa, Tuscaloosa, Walker, and Winston,
				located within the State of Alabama.
(d) "Large affected engine" means any
				affected engine whose average daily NOX emission rate was greater than one ton
				per day during the baseline period.
(e) "NOX potential to emit" means the maximum
				capacity of an engine to emit NOX under its physical and operational design or
				applicable permit condition for a given period of time. Any physical limitation
				on the capacity of a source's potential to emit an air pollutant, including air
				pollution control equipment or combustion modification, shall be treated as
				part of its design if the limitation is enforceable by the Director.
(f) "NOX SIP Call baseline period" or
				"baseline period" means the period beginning May 1, 1995, and ending on
				September 30, 1995, inclusive.
(g)
				"NOX SIP Call baseline period utilization" or "baseline utilization" means the
				amount of work performed by an affected engine during the baseline period in
				brake horsepower-hours (bhp-hr).
(h) "NOX SIP Call Inventory" means the NOX
				emission inventory published March 2, 2000 at 65 FR 11222 and amended April 21,
				2004 at 69 FR 21603.
(i) "Projected
				2007 Ozone Season Base NOX Emissions" or "projected 2007 emissions" means, for
				an affected engine, the projected uncontrolled NOX emissions (in tons) for the
				2007 ozone season as published in the NOX SIP Call Inventory and denoted as the
				variable labeled 'SNOX07'. For an affected engine that is not a large affected
				engine to which a control device is added or a combustion modification is made
				after September 30, 1995, if the Director approves a demonstration made by the
				person subject to this Rule that the Projected 2007 Ozone Season Base NOX
				Emissions published in the NOX SIP Call Inventory for that affected engine was
				not calculated from the correct 1995 ozone season emissions, the Projected 2007
				Ozone Season Base NOX Emissions for that affected engine will be the product of
				its uncontrolled 1995 NOX hourly emission rate (lb/hr), the number of hours it
				operated during the 1995 ozone season, and the 1995-2007 growth factor assigned
				to that affected engine in the NOX SIP Call Inventory denoted as the variable
				labeled 'GF9507.' The demonstration should provide representative emission test
				data or manufacturer's emission data for the affected engine applicable during
				the 1995 ozone season and records documenting its hours of operation during the
				1995 ozone season.
(j) "Projected
				2007 Ozone Season utilization" or "projected utilization" means the baseline
				utilization of an affected engine multiplied by the 1995-2007 growth factor
				assigned to that affected engine in the NOX SIP Call Inventory denoted as the
				variable labeled 'GF9507.'
(k)
				"Ozone season" means the period beginning May 1 of a year and ending on
				September 30 of the same year, inclusive.
(l) "Stationary reciprocating internal
				combustion engine" or "engine" means any reciprocating internal combustion
				engine which uses reciprocating motion to convert heat energy into mechanical
				work and which is not self-propelled or intended to be propelled while
				performing its function.
