NR 440.56(1)(1) Applicability and designation of affected facility. NR 440.56(1)(a)(a) Except as provided in par. (b), the affected facility to which the provisions of this section apply is each publication rotogravure printing press. NR 440.56(1)(b)(b) The provisions of this section do not apply to proof presses. NR 440.56(1)(c)(c) Any facility under par. (a) that commences construction, modification or reconstruction after October 28, 1980 is subject to the requirements of this section. NR 440.56(2)(a)(a) As used in this section, terms not defined in this paragraph have the meanings given in s. NR 440.02. NR 440.56(2)(a)1.1. “Automatic temperature compensator” means a device that continuously senses the temperature of fluid flowing through a metering device and automatically adjusts the registration of the measured volume to the corrected equivalent volume at a base temperature. NR 440.56(2)(a)2.2. “Base temperature” means an arbitrary reference temperature for determining liquid densities or adjusting the measured volume of a liquid quantity. NR 440.56(2)(a)3.3. “Density” means the mass of a unit volume of liquid, expressed as grams per cubic centimeter, kilograms per liter or pounds per gallon, at a specified temperature. NR 440.56(2)(a)4.4. “Gravure cylinder” means a printing cylinder with an intaglio image consisting of minute cells or indentations specially engraved or etched into the cylinder’s surface to hold ink when continuously revolved through a fountain of ink. NR 440.56(2)(a)5.5. “Performance averaging period” means 30 calendar days, one calendar month or 4 consecutive weeks as specified in subsections of this section. NR 440.56(2)(a)6.6. “Proof press” means any device used only to check the quality of the image formation of newly engraved or etched gravure cylinders and which prints only nonsaleable items. NR 440.56(2)(a)7.7. “Publication rotogravure printing press” means any number of rotogravure printing units capable of printing simultaneously on the same continuous web or substrate and includes any associated device for continuously cutting and folding the printed web, where the following saleable paper products are printed: catalogues, including mail order and premium; direct mail advertisements, including circulars, letters, pamphlets, cards and printed envelopes; display advertisements, including general posters, outdoor advertisements, car cards, window posters, counter and floor displays, point-of-purchase and other printed display material; magazines; miscellaneous advertisements, including brochures, pamphlets, catalogue sheets, circular folders, announcements, package inserts, book jackets, market circulars, magazine inserts and shopping news; newspapers, magazine and comic supplements for newspapers, and preprinted newspaper inserts, including hi-fi and spectacolor rolls and sections; periodicals; and telephone and other directories, including business reference services. NR 440.56(2)(a)9.9. “Related coatings” means all non-ink purchased liquids and liquid-solid mixtures containing VOC solvent, usually referred to as extenders or varnishes, that are used at publication rotogravure printing presses. NR 440.56(2)(a)10.10. “Rotogravure printing unit” means any device designed to print one color ink on one side of a continuous web or substrate using a gravure cylinder. NR 440.56(2)(a)11.11. “Solventborne ink systems” means ink and related coating mixtures whose volatile portion consists essentially of VOC solvent with not more than 5 weight percent water, as applied to the gravure cylinder. NR 440.56(2)(a)12.12. “Solvent recovery system” means an air pollution control system by which VOC solvent vapors in air or other gases are captured and directed through one or more condensers or a vessel containing beds of activated carbon or other adsorbents. For the condensation method, the solvent is recovered directly from the condenser. For the adsorption method, the vapors are adsorbed, then desorbed by steam or other media, and finally condensed and recovered. NR 440.56(2)(a)14.14. “VOC solvent” means an organic liquid or liquid mixture consisting of VOC components. NR 440.56(2)(a)15.15. “Waterborne ink systems” means ink and related coating mixtures whose volatile portion consists of a mixture of VOC solvent and more than 5 weight percent water, as applied to the gravure cylinder. NR 440.56(2)(b)1.1. DB is the density at the base temperature of VOC solvent used or recovered during one performance averaging period.
