Applicability A. This regulation applies statewide. This regulation applies to any Offset Lithography (Heatset, Sheet Fed or Coldset) and Letterpress printing operation: (1) whose maximum actual emissions are greater than three tons of VOCs per rolling 12 month period; (2) for non-heatset printing operations, whose total volume of cleaning solution, alcohol fountain solution, alcohol substitutes, coatings and ink purchased or used in any 30 day rolling period is greater than 64 gallons per month, or equivalently, 768 gallons in any 12 month rolling period; or (3) for heatset printing operations whose total weight of heatset inks, cleaning solution, fountain solution and fountain solution additives purchased or used in any 30 day rolling period is greater than 450 pounds per month, or equivalently, 5400 pounds per 12 month rolling period. Any person claiming exemption pursuant to this subsection shall record and maintain monthly operational records sufficient to demonstrate compliance as specified in Subsection 5A(7) of this Chapter. NOTE: Graphic Arts Flexography and Rotogravure printing operations are subject to Graphic Arts Rotogravure and Flexography, 06-096 CMR 132 (effective February 10, 1993). NOTE: Facilities or any owner that emits greater than 10 pounds per hour, 100 pounds per day of VOCs may have additional air licensing requirements and should contact the Department to determine whether any licensing requirements apply. C. Any owner or operator of an offset lithographic or letterpress printing operation, who is subject to this Chapter, must demonstrate compliance by 12 months from the effective date of this Chapter. For a source that commences operation after the effective date of this Chapter, the owner or operator must determine compliance status by 12 months after the date on which the source commences operation. Any owner or operator of an offset lithographic or letterpress printing operation, who is subject to this Chapter and has a BACT analysis included in an air emission license must demonstrate compliance pursuant to their air emission license conditions. D. Any printing operation that is subject to this Chapter due solely to exceeding the applicability threshold of three tons of VOC emissions per year in subsection 1B, and whose VOC emissions subsequently fall below that applicability threshold for a rolling 12 month period will remain subject to the requirements of this Chapter for three years following the conclusion of that 12 month rolling period. The printing operation will become subject to this Chapter anew upon exceeding any applicability threshold set forth in subsection 1B. 2. Definitions Actual Emissions. Actual Emissions means calculating a VOC mass balance over a period of time, using invoices and usage records to determine amounts of ink, fountain solution and cleaning solutions purchased and used; multiplied by an applicable emission retention factor. Alcohol. Alcohol means any of the following compounds, when used as a fountain solution additive for offset lithographic or letterpress printing: ethanol, n-propanol, and isopropanol. Alcohol substitute. Alcohol substitute means any non-alcohol additives that contain VOCs and are used in the fountain solution; including, but not limited, to ethylene glycol or glycol ether compounds. Some additives are used to reduce the surface tension of water: others are added to prevent piling (ink build-up). Automatic Blanket Wash System. Automatic Blanket Wash System means equipment used to clean lithographic blankets which can include, but is not limited to, those utilizing a cloth and expandable bladder, brush, spray, or impregnated cloth system. BACT. BACT means Best Available Control Technology as defined in Definitions Regulation 06-096 CMR 100 effective December 24, 2005). CAM.

Cleaning Solution means any liquid solvent or solution used to clean the operating surfaces of a printing press and its parts. For purposes of this Chapter, 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. 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. Dampening System. "Dampening system" means equipment used to deliver the fountain solution to the lithographic plate. Fountain Solution. Fountain solution means a mixture of water and other volatile and non-volatile chemicals and additives that maintains the quality of the printing plate including preventing debris build up (e.g., spray power, paper fiber, coating particles, dried ink particles and other materials), and increases viscosity and reduces the surface tension of the water so that is spreads easily across the printing plate service. The fountain solution wets the non-image area so that the ink is maintained within the image areas. Non-volatiles additives include mineral salts and hydrophilic gums. Alcohol and alcohol substitutes are the most common VOC additives used to reduce the surface tension of the fountain solution. Fountain Solution Reservoir. Fountain Solution Reservoir means the collection tank that accepts fountain solution recirculated from printing unit(s). In some cases, the tanks are equipped with cooling coils for refrigeration of the fountain solution. Heatset. Heatset means any operation where the printing inks are set by the evaporation of the ink oils in a heatset dryer. Heatset Dryer. Heatset dryer means any device used in heatset web offset lithographic printing to heat the printed substrate and to promote the evaporation of ink oils. Inking System. Inking System means a series of rollers used to meter ink onto the lithographic plate. The system can include agitators, pumps, totes, and others types of ink containers. Letterpress printing press. Letterpress Printing press means a printing press that uses a relief method which uses type directly. Printing is done from cast metal type or plates on which the image or printing areas is raised above the nonprinting areas. Ink rollers touch on the surface of the raised areas. The surrounding (nonprinting) areas are lower and do not receive ink. The inked image is transferred directly to the paper. Lithography. Lithography means a planographic printing process where the image and nonimage areas are chemically differentiated; the image area is oil receptive and the nonimage area is water receptive. This method differs from other printing methods, where the image is typically printed from a raised or recessed surface. Non-heatset. Non-heatset means a printing process where the printing inks are set by absorption and/or oxidation of the ink oil, not by evaporation of the ink oils in a dryer. For the purposes of this Chapter, use of an infrared heater or printing conducted using ultraviolet-cured or electron beam-cured inks is considered non-heatset. Offset. Offset means a printing process that transfers the ink film from the lithographic plate to an intermediary surface (blanket), which, in turn, transfers the ink film to the substrate. Press. "Press" means printing production assembly composed of one or more units used to produce a printed substrate including any associated coating, spray power application, heatset web dryer, ultraviolet or electron beam curing units, or infrared heating units. Sheet fed. Sheet fed means any operation where paper is fed to the press in individual sheets. Substrate. "Substrate" means the surface to which a coating is applied. VOC Composite Partial Vapor Pressure VOC Composite Partial Vapor Pressure means the sum of the partial pressure of the compounds defined as VOCs. VOC composite partial vapor pressure is calculated as follows:  EMBED Equation.2  Where: Wi = Weight of the ith VOC compound, in grams Ww = Weight of water, in grams Wc = Weight of exempt compound, in grams MWi = Molecular weight of the ith 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 20C (68F), in mm Hg VPi = Vapor pressure of the ith VOC compound at 20C (68F), in mm Hg W.
