Current through Register Vol. 50, No. 6, June 20, 2024
A. For purposes of
				  this regulation, the following definitions and abbreviations apply.
BE
- a building or room enclosure that
					 contains a process that emits VOC. If a BE is to serve as a PTE or TTE, the
					 appropriate requirements given in  40 CFR, Part 51, Appendix M, Method 204 must
					 be met.
Capture
- the containment or recovery of
					 emissions from a process for direction into a duct which may be exhausted
					 through a stack or sent to a control device.
Capture Efficiency
- the weight per unit
					 time of VOC entering a capture system and delivered to a control device divided
					 by the weight per unit time of total VOC generated by a source of VOC,
					 expressed as a percentage.
Capture System
- all equipment (including,
					 but not limited to, hoods, ducts, fans, booths, ovens, dryers, etc.) that
					 contains, collects and transports an air pollutant to a control device.
Control Device
- equipment (such as an
					 incinerator or carbon adsorber) used to reduce, by destruction or removal, the
					 amount of air pollutant(s) in an air stream prior to discharge to the ambient
					 air.
Control System
- a combination of one or
					 more capture system(s) and control devices working in concert to reduce
					 discharges or pollutants to the ambient air.
Destruction or Removal Efficiency
- the
					 efficiency, expressed as a decimal fraction, of a control device in destroying
					 or removing contaminants calculated as one minus the amount of VOC exiting the
					 control device divided by the amount of VOC entering the control device.
F
- the mass of VOC leaving the process as
					 gaseous fugitive emissions.
G
- the mass of VOC captured and delivered
					 to a control device.
Gas/Gas Method
- either of two methods for
					 determining capture which rely only on gas phase measurements. One method
					 requires construction of a temporary enclosure (TTE) to assure all would be
					 fugitive emissions are measured while the other method uses the room or
					 building which houses the emission source as an enclosure.
Hood
- a partial enclosure or canopy for
					 capturing and exhausting, by means of a draft, the organic vapors or other
					 fumes rising from a coating process or other source.
L
- the mass of VOC input to the process
					 in liquid form.
Liquid/Gas Method
- either of two methods
					 for determining capture which require both gas phase and liquid phase
					 measurements and analysis. One liquid/gas method requires construction of a
					 temporary enclosure, the other uses the building or room which houses the
					 facility as an enclosure.
Overall Emission Reduction Efficiency
-
					 the weight per unit time of VOC removed by a control device divided by the
					 weight per unit time of VOC emitted by an emission source, expressed as a
					 percentage. The overall emission reduction efficiency is the product of the
					 capture efficiency and the control equipment destruction or removal
					 efficiency.
PTE
- a permanent total enclosure, which
					 contains a process that emits VOC and meets the specifications given in  40 CFR,
					 Part 51, Appendix M, Method 204, Section 6.
TTE
- a temporary total enclosure which is
					 built around a process that emits VOC and meets the specifications given in  40
					 CFR, Part 51, Appendix M, Method 204, Section 5.
