Current through Register Vol. 46, No. 28, July 10, 2024
(a) For the purpose
				  of this Part, the general definitions of Part 200 of this Title
				  apply.
(b) For the purpose of this
				  Part, the following definitions also apply:
(1) Alcohol. Ethanol, n-propanol, and
				  isopropanol.
(2) Alcohol
				  substitute. A non-alcohol additive that contains VOC and is used in a fountain
				  solution to reduce the surface tension of water or to prevent piling (ink
				  build-up).
(3) As applied. The VOC
				  concentration of ink, coating, or adhesive at the time it is applied to a
				  substrate; or the alcohol (or alcohol substitute) concentration of a fountain
				  solution at the time it is applied to lithographic press plates.
(4) Capture system. All equipment including,
				  but not limited to, hoods, ducts, fans, booths, ovens, or dryers that contain,
				  collect, and transport an air pollutant to control equipment.
(5) Cleaning materials. A liquid solvent or
				  solution used to remove ink and debris from the operating surfaces of the
				  printing press and its parts. For purposes of this rule, cleaning solutions
				  include, but are not limited to blanket wash, roller wash, metering roller
				  cleaner, plate cleaner, impression cylinder washes, rubber rejuvenators, and
				  other cleaners used for cleaning a press, press parts, or to remove dried ink
				  or coating from areas around the press.
(6) Cold-set printing process or non-heatset
				  printing process.A printing process that uses absorption, oxidation,
				  ultraviolet light, electron bean or other non-heat method to cure the printing
				  ink.
(7) Composite partial vapor
				  pressure. The sum of the partial pressure of the compounds defined as VOCs. VOC
				  composite partial vapor pressure is calculated as follows:
Image
Where:
Wi =Weight of the "i"th VOC compound, in grams
Ww =Weight of water, in grams
Wc =Weight of exempt compound, in grams
Mwi =Molecular weight of the "i"th VOC compound, in
					 g/g-mole
MWw =Molecular weight of water, in g/g-mole
MWc =Molecular weight of exempt compound, in
					 g/g-mole
PPc =VOC composite partial vapor pressure at 20° C
					 (68° F), in mm Hg
Vpi =Vapor pressure of the "i"th VOC compound at 20° C
					 (68° F), in mm Hg
(8)
				  Control equipment. The equipment used to destroy or remove VOC emissions from
				  graphic art printing processes.
(9)
				  Digital printing press. A printing press that transfers electronic files from a
				  computer to an electronically driven output device that prints the image
				  directly on a substrate. Also known as direct-to-media printing.
(10) Excluded compound. A compound expressly
				  excluded from the definition of VOC in section
				  200.1  of this
				  Title.
(11) Flexographic printing
				  process. A printing process that raises the image to be applied above the
				  non-image area and uses an image carrier made of rubber or other elastomeric
				  materials.
(12) Fountain solution.
				  A solution of water, VOC, gum arabic, and surfactants used for wetting
				  lithographic press plates.
(13)
				  Graphic arts. Packaging rotogravure, publication rotogravure, flexographic,
				  offset lithographic, letterpress and screen printing processes.
(14) Heat-set printing process. A printing
				  process that uses heat to evaporate ink oils from the printing ink. Hot air
				  dryers are used to deliver the heat.
(15) Letterpress printing process. A printing
				  process in which the image is raised relative to the non-image and a paste ink
				  is transferred from the image surface directly to the substrate.
(16) Maximum permitted pounds of VOC per
				  gallon of ink, coating or adhesive, minus water and excluded compounds, at
				  application. The permissible quantity of VOC per gallon of ink, coating or
				  adhesive minus water and excluded compounds; calculated as follows:
(VOC)a = (Dc)a ( (Wv)a - (Ww)a - (We)a)/1 - ( (Vw)a +
					 (Ve)a)
where:
(VOC)a =VOC content of ink, coating or adhesive as
					 applied, expressed as a mass of VOC, in pounds, per volume of coating, in
					 gallons, minus water and excluded compounds
(Dc) a =ink, coating or adhesive density as applied, in
					 pounds per gallon
(Wv)a =the weight fraction of total VOC in the ink,
					 coating or adhesive as applied
(Ww)a =the weight fraction of water in the ink, coating or
					 adhesive as applied
(Vw)a =the volume fraction of water in the ink, coating or
					 adhesive as applied
(We) a =the weight fraction of excluded compounds in the
					 ink, coating or adhesive as applied
(Ve) a =the volume fraction of excluded compounds in the
					 ink, coating or adhesive as applied.
(17) Offset lithographic printing process. A
				  planographic printing process that chemically differentiates the image and
				  non-image areas and uses a lithographic plate to transfer the image to an
				  intermediate surface which in turn transfers the image to the
				  substrate.
(18) Overall removal
				  efficiency. The total reduction in VOC emissions considering the efficiency of
				  both the capture system and subsequent destruction or removal of these
				  emissions by the control equipment prior to their release into the
				  atmosphere.
(19) Packaging
				  rotogravure printing process. A rotogravure printing process upon substrates
				  that are subsequently formed into wallpaper, packaging products, or labels for
				  articles to be sold.
(20) Printing
				  press. The equipment used to apply words, pictures, or designs to either a web,
				  or a sheet. A web is a continuous substrate of paper, plastic, or other
				  material that is unwound from a roll, passed through ink or coating applicators
				  and any associated drying areas. The press includes all ink and coating
				  applicators and drying areas between unwind and rewind of the continuous
				  substrate. A sheet consists of paper, plastic, or other material that is fed
				  through the press sequentially and carried through the process on a moving
				  belt. The press includes all ink and coating applicators and drying operations
				  from the time that the sheet is put on the moving belt until it is taken
				  off.
(21) Printing process. Any of
				  the various ways a printing press is operated.
(22) Proof press. A printing press used only
				  to check the quality of print color and editorial content.
(23) Publication rotogravure printing
				  process. A rotogravure printing process used to produce books, magazines,
				  catalogs, brochures, directories, newspaper supplements and similar types of
				  printed material.
(24) Rotogravure
				  printing process. An intaglio printing process that transfers the inked image
				  from minute etched or engraved wells on a plate or cylinder to the substrate
				  that is supported by an impression roller.
(25) Screen printing process. A printing
				  process that delivers ink through a woven mesh fitted with an ink blocking
				  stencil. The stencil and mesh openings determine the form and dimensions of the
				  imprint. Screen printing processes where the ink is applied by a hand held
				  squeegee are excluded from this definition.
(26) Serigraph. Fine art created or
				  reproduced using a screen printing press.
(27) Solvent. A substance that is liquid at
				  standard conditions and is used to dissolve or dilute another substance; this
				  term includes, but is not limited to, organic materials used as dissolvers,
				  viscosity reducers, degreasing agents, or cleaning agents. An excluded compound
				  is not a solvent.
