NR 422.142(2)(b)3.b. b. 8.5% by weight if the fountain solution is refrigerated to 60°F or less.

NR 422.142(2)(b)4. 4. ‘Metal, metal-foil or plastic substrates.’ Any person who owns or operates any lithographic printing press shall, when printing on a metal, metal-foil or plastic substrate, use a fountain solution which has a VOC content as applied of no more than one of the following:

NR 422.142(2)(b)4.a. a. 13.5% by weight if the fountain solution contains any restricted alcohol and is refrigerated to 60°F or less.

NR 422.142(2)(b)4.b. b. Not more than that allowed under subd. 1. a. or c., 2., or 3. a., as appropriate for the type of press operated.

NR 422.142(2)(c) (c) Cleaning solutions.

NR 422.142(2)(c)1. 1. Except as provided in subd. 2., any person who owns or operates any lithographic printing press shall use a cleaning solution which, as applied, has any of the following:

NR 422.142(2)(c)1.a. a. A VOC content of no greater than 70% by weight.

NR 422.142(2)(c)1.b. b. A VOC composite partial vapor pressure of less than or equal to 10 mm of Hg at 20°C (68°F).

NR 422.142(2)(c)2. 2. The owner or operator of a facility may use a cleaning solution that does not meet the emission limitations of subd. 1., provided the amount used at the facility under this subdivision over any 12 consecutive months does not exceed any of the following:

NR 422.142(2)(c)2.a. a. If the facility does not print on a plastic substrate, 55 gallons.

NR 422.142(2)(c)2.b. b. If the facility does print on a plastic substrate, 165 gallons.

NR 422.142(3) (3) Monitoring requirements.

NR 422.142(3)(a) (a) The owner or operator of any lithographic printing press shall monitor at least once each 8-hour shift the temperature of each fountain solution reservoir for any fountain solution subject to sub. (2) (b) 1. b., 3. b., or 4. a.

NR 422.142(3)(b) (b) The owner or operator of any lithographic printing press subject to the VOC control device requirements of sub. (2) (a) shall comply with the monitoring requirements in s. NR 422.143 (5) (b).

NR 422.142(4) (4) Recordkeeping requirements. In addition to the applicable recordkeeping requirements in s. NR 439.04, the owner or operator of any lithographic printing press shall collect and record the applicable information specified in this subsection. The information shall be maintained at the facility for a minimum of 5 years and shall be made available to an authorized department representative at any time during normal working hours. The information required is all of the following:

NR 422.142(4)(a) (a) For a heatset web lithographic printing press using a control device, all of the following:
