NR 422.142 NR 422.142 Lithographic printing — part 1.

NR 422.142(1) (1) Applicability.

NR 422.142(1)(a) (a) This section applies to all lithographic printing presses at any facility that is located in Kewaunee or Manitowoc county, was constructed before July 1, 2019, and has maximum theoretical emissions of VOCs from all lithographic printing presses at the facility greater than or equal to 755.7 kilograms (1666 pounds) in any month.

NR 422.142(1)(b) (b) To determine VOC emissions under par. (a), the VOC content of a lithographic ink shall be multiplied by 0.8 for a heatset ink, or multiplied by 0.05 for a non-heatset ink, to account for VOC retention on the substrate.

NR 422.142(1m) (1m) Retention factors and capture efficiencies. For purposes of determining VOC emissions from offset lithographic printing operations, the following retention factors and capture efficiencies may be used:

NR 422.142(1m)(a) (a) A 20% VOC retention factor for heatset inks printed on absorptive substrates, meaning 80% of the VOC in the ink is emitted during the printing process and is available for capture and control by an add-on pollution control device.

NR 422.142(1m)(b) (b) A 95% VOC retention factor for sheet-fed and non-heatset web inks printed on absorptive substrates, meaning 5% of the VOC in the ink is emitted during the printing process.

NR 422.142(1m)(c) (c) A 50% VOC retention factor for cleaning solution in shop towels where the composite partial vapor pressure of the VOC in the cleaning solution is less than 10 mm of Hg at 20°C (68°F) and the cleaning solution and contaminated shop towels are kept in closed containers, meaning 50% of the VOC used on the shop towels is emitted during the cleaning process.

NR 422.142(1m)(d) (d) A 100% VOC capture efficiency for inks. All the VOC in the ink that is not retained is assumed to be volatilized in the press dryer. Capture efficiency testing for heatset dryers is not required if it is demonstrated that pressure in the dryer is negative relative to the surrounding press room and the airflow is into the dryer.

NR 422.142(1m)(e) (e) A 70% VOC capture efficiency for fountain solutions containing alcohol substitutes.
