R307-351-3.  Exemptions.
	(1)  The provisions of R307-351 shall not apply to graphic arts materials that have a VOC content of less than 25 g/L , minus water and exempt VOCs, as applied.
	(2)  A graphic arts printing operation may use up to 55 gallons of cleaning materials per year that do not comply with the VOC composite vapor pressure requirement or the VOC content requirement in R307-351-5(4).
	(3)  The provisions of R307-351 shall not apply to medical devices and their packaging.

R307-351-4.  Definitions.
	The following additional definitions apply to R307-351:
	"Alcohol" means any of the following compounds, when used as a fountain solution additive for offset lithographic printing: ethanol, n-propanol, and isopropanol.
	"Alcohol Substitute" means a non-alcohol additive that contains VOCs and is used in the fountain solution.
	"Cleaning materials and solutions" means a liquid solvent or solution used to clean the operating surfaces of a printing press and its parts. Cleaning materials and 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.
	"Blanket" means a synthetic rubber material that is wrapped around a cylinder used in offset lithography to transfer or "offset" an image from an image carrier.
	"Control system" means the combination of capture and control devices used to reduce emissions to the atmosphere.
	"Flexographic printing" means the application of words, designs, and pictures to substrate by means of a roll printing technique in which the pattern to be applied is raised above the printing roll and the image carrier is made of rubber or other elastomeric materials.
	"Fountain solution" means a mixture of water and other volatile and non-volatile chemicals and additives that wets the non-image area of a lithographic printing plate so that the ink is maintained within the image areas.
	"Graphic arts materials" means any inks, coatings, or adhesives, including added thinners or retarders, used in printing or related coating or laminating processes.
	"Graphic arts printing" means the application of words and images using the offset lithographic, letterpress, rotogravure, or flexographic printing process.
	"Heatset" means an offset lithographic printing or letterpress printing operation in which the ink solvents are vaporized by passing the printed surface through a dryer.
	"Letterpress printing" means a method where the image area is raised relative to the non-image area and the ink is transferred to the substrate directly from the image surface.
	"Non-heatset", also called coldset, means an offset lithographic printing or letterpress printing operation in which the ink dries by oxidation and/or absorption into the substrate without use of heat from dryers. For the purposes of this rule, use of an infrared heater or printing conducted using ultraviolet-cured or electron beam-cured inks is considered non-heatset.
	"Medical device" means an instrument, apparatus, implement, machine, contrivance, implant, in vitro reagent or other similar article including any component or accessory, that is intended for use in the diagnosis of disease or other conditions or in the cure, mitigation, treatment, or prevention of disease, or is intended to affect the structure or any function of the body.  For the purpose of this rule, a medical device shall also include associated manufacturing or assembly apparatus.
	"Offset lithographic printing" means a plane-o-graphic method in which the image and non-image areas are on the same plane and the ink is offset from a plate to a rubber blanket, and then from the blanket to the substrate.
	"Printing operation" means the application of words, designs, or pictures on a substrate. All units in a machine which have both coating and printing units shall be considered as performing a printing operation.
	"Rotogravure printing" means the application of words, designs, and pictures to a substrate by means of a roll printing technique that involves a recessed image area in the form of cells.
	"Web" means a continuous roll of substrate.

R307-351-6.  Add-on Controls Systems Operations.
	(1)  If an add-on control system is used, the owner or operator shall install and maintain the add-on emission control system in accordance with the manufacturer recommendations.
	(a)  Control devices for individual heatset web offset lithographic printing presses and individual heatset web letterpress printing press dryers that were installed prior to January 1, 2017, must maintain a 90% or greater control efficiency. Similar control devices installed after January 1, 2017, must maintain a 95% or greater control efficiency.
	(b)  Control devices for individual flexographic printing presses and individual rotogravure printing presses shall comply with a 90% or greater overall control efficiency.
	(c)  As an alternative to the control efficiency, the control device outlet concentration may be reduced to 20 ppmv as hexane on a dry basis to accommodate situations where the inlet VOC concentration is low or there is no identifiable measurable inlet. The control outlet concentration shall be determined using EPA Method 25A.
	(d)  The capture efficiency of a VOC emission control system's VOC collection device for flexographic and rotogravure presses shall be determined according to EPA's "Guidelines for Determining Capture Efficiency," January 9, 1995 and 40 CFR Part 51, Appendix M, Methods 204-204F, as applicable.
	(e)  The capture efficiency of a VOC emission control system's VOC collection device for a heatset web offset press shall be determined by demonstrating that the airflow in the dryer is negative to the surrounding pressroom during the initial test using an air flow direction indicator, such as a smoke stick or aluminum ribbons, or differential pressure gauge.
	(f)  The control efficiency of a VOC emission control system's VOC control device shall be determined using test methods in Appendices A-1, A-6, and A-7 to 40 CFR Part 60, for measuring flow rates, total gaseous organic concentrations, or emissions of exempt compounds, as applicable.
	(g)  An alternative test method may be substituted for the preceding test methods after review and approval by the EPA Administrator.

R307-351-8.  Recordkeeping.
	(1)  The owner or operator shall maintain records of the following:
	(a)  Records that demonstrate compliance with R307-351. Records must include, but are not limited to, inventory and product data sheets of all graphic arts materials and cleaning solutions subject to R307-351.
	(b)  If an add-on control device is used, records of key system parameters necessary to ensure compliance with R307-351-6. Key system parameters include, but are not limited to, temperature, pressure, flow rates, and an inspection schedule. Key inspection parameters shall be in accordance with the manufacturer's recommendations, and as required to demonstrate that operations provide continuous emission reduction from the source during all periods that the operations cause emissions from the source.
	(2)  All records shall be maintained for a minimum of 2 years.
	(3)  Records shall be made available to the director upon request.
