Current through Register Vol. 40, No. 24, July 15, 2024
A. For the purpose
					 of applying this article in the context of the Regulations for the Control and
					 Abatement of Air Pollution and related uses, the words or terms shall have the
					 meanings given them in subsection C of this section.
B. As used in this article, all terms not
					 defined here shall have the meanings given them in 9VAC5-10, unless otherwise
					 required by context.
C. Terms
					 defined.
"Capacity factor" means the ratio of the average load on
						a machine or equipment for the period of time considered to be the capacity
						rating of the machine or equipment.
"Combustion modification" means any change to the
						configuration of the burners or the firing method or mechanism of any
						combustion equipment for the purpose of reducing the emissions of nitrogen
						oxides. Acceptable combustion equipment changes within the context of this term
						include, but are not limited to, reburning, burners out of service, flue gas
						recirculation, fuel substitution, engine adjustments, engine modifications,
						fuel modifications and the addition of over fire air and low nitrogen oxides
						burner systems.
"Fossil fuel" means natural gas, petroleum, coal and any
						form of solid, liquid or gaseous fuel derived from such materials for the
						purpose of creating useful heat.
"Fuel burning equipment" means any furnace, with fuel
						burning equipment appurtenances thereto, used in the process of burning fuel
						for the primary purpose of producing heat to be utilized by indirect heat
						transfer or producing power. This includes facilities that are designed as
						boilers to produce steam or heated water and are designed to burn either fossil
						fuel or refuse derived fuel. It does not include such facilities if designed
						primarily to burn raw refuse.
"Gas turbine" means a rotary internal combustion engine
						fueled by liquid or gaseous fuel.
"Heat input" means the total gross calorific value of
						all fuels burned.
"Incinerator" means any device, apparatus, equipment, or
						structure using combustion or pyrolysis for destroying, or reducing the volume
						of any material or substance.
"Internal combustion engine" means a reciprocating
						engine that is fueled by liquid or gaseous fuel.
"Presumptive RACT" means the emission limit that a
						particular source is capable of meeting by the application of reasonably
						available control technology that is defined in
						9VAC5-40-7430.
"Process heater" means any fuel burning equipment that
						is used to produce heat for use in a manufacturing process. This term includes
						boilers that use a heat transfer medium other than water, but does not include
						drying ovens, steam generating units, or other drying apparatus.
"Rated capacity" means the capacity as stipulated in the
						purchase contract for the condition of 100% load, or such other capacities as
						mutually agreed to by the board and owner using good engineering
						judgment.
"Reasonably available control technology" or "RACT"
						means the lowest emission limit that a particular source is capable of meeting
						by the application of control technology that is reasonably available,
						considering technological and economic feasibility.
"Refuse derived fuel (RDF)" means fuel produced from
						solid or liquid waste (includes materials customarily referred to as refuse and
						other discarded materials) or both that has been segregated and classified,
						with the useable portions being put through a size reduction and classification
						process which results in a relatively homogeneous mixture.
"Steam generating unit" means any furnace, boiler or
						other device used for combusting fuel for the purpose of producing
						steam.
"Theoretical potential to emit" means the maximum
						capacity of a stationary source to emit a pollutant based on emissions at
						design capacity or maximum production and maximum operating hours (8,760
						hours/year) before add-on controls, unless the facility is subject to state and
						federally enforceable permit conditions that limit production rates or hours of
						operation. Emissions from all facilities, including facilities exempt from any
						other emission standard for volatile organic compounds or nitrogen oxides in
						this chapter, shall be added together to determine theoretical potential to
						emit.
"Tpy" means tons per year.
