A.
General coating definitions
(1)
Air-dried coating
.
				"Air-dried coating" means a coating that is dried by the use of air or forced
				warm air at temperatures up to 90 degrees Celsius (C) (194 degrees Fahrenheit
				(F)).
(2)
Baked
				coating
. "Baked coating" means a coating that is cured at a temperature
				at or above 90 degrees Celsius (C) (194 degrees Fahrenheit (F)).
(3)
Coating
. "Coating" means a
				material applied in a thin layer to a surface as a protective, decorative, or
				functional film. This term often refers to paints such as lacquers or enamels,
				but also refers to films applied to other materials such as varnishes,
				sealants, adhesives, inks, maskants, and temporary protective coatings. Such
				materials include, but are not limited to, paints, varnishes, sealants,
				adhesives, inks, maskants, and temporary protective coatings.
(4)
Coating unit
. "Coating unit"
				means a series of one or more coating applicators and any associated drying
				area or oven wherein a coating is applied, dried, or cured. A coating unit ends
				at the point where the coating is dried or cured, or prior to any subsequent
				application of a different coating. A surface coating operation does not
				require an oven or flashoff area in order to be included in this
				definition.
(5)
Control
				device
. "Control device" means equipment used to reduce, by destruction
				or removal, the amount of air pollutant(s) in an air stream prior to discharge
				to the ambient air.
(6)
Day
. "Day" means a period of 24 consecutive hours beginning at
				midnight, local time, or beginning at a time consistent with a surface coating
				facility's operating schedule.
(7)
Exempt compounds
. See VOC definition in Chapter 100.
(8)
Flashoff area
. "Flashoff
				area" means the space between the coating application area and the
				oven.
(9)
Major
				Subassembly
. "Major Subassembly" means a unit assembled separately but
				designed to be incorporated with other units into a larger manufactured product
				which performs a significant function such as propulsion, directional control,
				or is a significant portion of the exterior of the vessel or aircraft. Major
				subassemblies do not include simple items such as fixtures and
				fittings.
(10)
Maximum
				theoretical emissions
. "Maximum theoretical emissions" means the
				quantity of VOC that theoretically could be emitted by a surface coating unit,
				line or operation without control devices and is based on one of the following:
(a) The design capacity or maximum production
				capacity of the surface coating facility and 8,760 hours of operation per 12
				month rolling period; or
(b) Hours
				of operation and/or design and/or process conditions, including operation
				rates, that are limited by enforceable permit conditions. Such permit
				conditions include short term limits (e.g., the number of operating hours per
				30 day rolling average) and corresponding recordkeeping provisions.
The design capacity or maximum production capacity includes
				  use of coatings and inks with the highest VOC content used in practice by the
				  surface coating facility for the two (2) years preceding the effective date of
				  this chapter.
(11)
Normally closed container
.
				"Normally closed container" means a container that is closed unless an operator
				is actively engaged in activities such as emptying or filling the container.
(12)
Oven
. "Oven"
				means a chamber which is used to bake, cure, polymerize or dry a
				coating.
(13)
Plastisol
. "Plastisol" means a coating made of a mixture of finely
				divided resin and a plasticizer. Plastisol is applied as a thick gel that
				solidifies when heated.
(14)
Prime coat
. "Prime coat" means the first of two (2) or more
				coatings applied to a surface.
(15)
Roller coating
. "Roller coating" means the application of a
				coating to a substrate by means of hard rubber or metal rolls.
(16)
Substrate
. "Substrate"
				means the surface to which a coating is applied.
(17)
Web coating line
. "Web
				coating line" means all of the coating applicator(s), drying area(s), or
				oven(s), located between an unwind station and a rewind station, that are used
				to apply coating onto a continuous strip of substrate (the web). A web coating
				line need not have a drying oven in order to be included in this
				definition.
