					 otherwise required by context.
C.
					 Terms defined.
"Carbon adsorption system" means a device containing
						activated carbon as the adsorbent material, an inlet and outlet for exhaust
						gases, and a system to regenerate the saturated adsorbent. The carbon
						adsorption system must provide for the proper disposal or reuse of all volatile
						organic compounds in the adsorbate.
"Compliant ink or surface coating" means an ink or
						surface coating conforming to the definition of a high-solids, low-volatile
						organic compound or a waterborne ink or surface coating.
"Cleaning solutions" means any liquid used to remove ink
						and debris from the operating surface of a printing press and its parts.
"Electrostatic duplication" means a process using a
						plate or takeoff sheet that is electrically charged to attract developer to the
						image area only.
"Flexographic printing" means the application of words,
						designs or pictures by a rubber or elastomeric image carrier in which the image
						area is raised above the nonimage area.
"High-solids ink or surface coating" means an ink or
						surface coating which contains 60% or more nonvolatile compounds by
						volume.
"Letterpress printing" means a printing process which
						uses raised image transfer elements fixed upon a metal backing.
"Lithographic printing" means a planographic printing
						process in which the image and nonimage areas are chemically differentiated
						with the image area being oil receptive and the nonimage area being water
						receptive.
"Low-solvent ink or surface coating" means an ink or
						surface coating which contains not more than 0.5 pounds of volatile organic
						compounds per pound of nonvolatile compounds and is used on a packaging
						rotogravure printing or flexographic printing press.
"Noncompliant ink or surface coating" means an ink or
						surface coating which does not conform to the definition of a high-solids,
						low-volatile organic compound or waterborne ink or surface coating.
"Packaging rotogravure printing" means an intaglio
						printing process in which the ink is transferred from minute etched wells on an
						image carrier, typically a cylinder, to paper, paper board, metal foil, plastic
						film and other substrates, which are, in subsequent operations, formed into
						containers and labels for articles to be sold.
"Printing" means a photomechanical process in which a
						transfer of text, designs, and images occurs through contact of an image
						carrier with a substrate.
"Printing line" means all of the equipment between a web
						feed input and the finished rolled or cut and stacked product wherein printing
						ink or a combination of printing inks and surface coatings are applied, dried,
						or cured and which is subject to the same emission standard. Such equipment may
						include decks, stations, press units, devices, ink stations, and any other
						equipment which applies, conveys, dries, or cures surface inks or surface
						coatings. Such equipment may include but is not limited to flow coaters,
						flashoff areas, air dryers, drying areas, and ovens. It is not necessary for a
						printing line to have an oven, flashoff area, or drying area to be included in
						this definition.
"Printing process" means any operation or system wherein
						printing ink or a combination of printing ink and surface coating is applied,
						dried or cured and which is subject to the same emission standard. May include
						any equipment which applies, conveys, dries or cures inks or surface coatings,
						including, but not limited to, flow coaters, flashoff areas, air dryers, drying
						areas and ovens. It is not necessary for a printing process to have an oven,
						flashoff area or drying area to be included in this definition.
"Publication rotogravure printing" means an intaglio
						printing process in which the ink is transferred from minute etched wells on an
						image carrier, typically a cylinder, to paper which is subsequently formed into
						books, magazines, catalogues, brochures, directories, newspaper supplements or
						any other types of printed materials not included under the definition of
						packaging rotogravure printing.
"Surface coating" means all nonink liquids and
						liquid-solid mixtures containing volatile organic compounds which are applied
						to the substrate by printing units.
"Waterborne ink" or "surface coating" means an ink or
						surface coating whose volatile portion consists of 75% or more by volume of
						water and 25% or less by volume of volatile organic compounds.
"Web" means a continuous roll of printing
						substrate.
