NR 422.144(4)(b)(b) Blanket or roller wash. Except as provided in sub. (3) (a), on and after May 1, 2012, no owner or operator of a letterpress printing press may use, or cause, allow or permit the use of a blanket or roller wash with a VOC composite vapor pressure of greater than or equal to 10 mm of Hg at 68°F or greater than or equal to 70% by weight.

NR 422.144(5)(a)(a) Beginning on February 1, 2012, the owner or operator of a letterpress press subject to this subsection shall store all solvents, solvent solutions and any shop towels or other applicator moistened with solvents or solvent solutions that are used in cleaning operations related to letterpress printing in covered non-absorbent, non-leaking containers, except when filling or emptying the container.

NR 422.144(6)(6) Recordkeeping requirements. In addition to the applicable recordkeeping requirements in s. NR 439.04, the owner or operator of any letterpress 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 a department representative at any time during normal working hours. The information required is:

NR 422.144(6)(a)(a) For a heatset web letterpress printing press using a control device, for each day of operation:

NR 422.144(6)(a)3.3. A maintenance log for the control device and control device monitoring equipment detailing all routine and non-routine maintenance performed and including the dates and duration of any outages.

NR 422.144(6)(b)(b) For each blanket or roller wash batch, monthly records of the percent by weight VOC content or the composite partial vapor pressure, as applied, and the date and time the batch was prepared.

NR 422.144(6)(c)(c) For each month of operation, the volume of all blanket or roller wash used which does not meet either of the emission limitations in sub. (4) (b).

NR 422.144(7)(a)(a) The owner or operator of a heatset web letterpress printing press shall demonstrate compliance with the appropriate destruction efficiency or emission rate in sub. (4) (a) by performing compliance emission tests on each control device. The initial emission tests shall be performed by the compliance deadline in sub. (8) (a) 1. or (b) 1. or 2. Each emission test shall follow the methods and procedures listed in s. NR 439.07. Method 25 or 25A in 40 CFR part 60, Appendix A, incorporated by reference in s. NR 484.04 (19) and (20), shall be used to determine the VOC concentration at the sampling points, including the exhaust stream entering and existing the control device. When determining the VOC concentration, the probe shall be heated during testing to at least the exhaust gas stream temperature. In cases where the anticipated outlet VOC concentration of the control device is less than 50 ppmv as carbon, Method 25A shall be used.

NR 422.144(7)(b)(b) The owner or operator of a heatset web letterpress printing press shall perform the compliance emission tests required under par. (a) according to one of the following applicable test schedules:

NR 422.144(7)(b)1.1. Any facility with allowable VOC emissions from letterpress printing presses of 100 tons or more per year shall perform an emission test which demonstrates compliance with sub. (4) (a) every 24 months. Each biennial test shall be performed within 90 days of the anniversary date of the initial emission test.

NR 422.144(7)(b)2.2. Any facility with allowable VOC emissions from letterpress printing presses of less than 100 tons per year shall perform an emission test which demonstrates compliance with sub. (4) (a) every 48 months. Each test shall be performed within 90 days of the anniversary date of the initial emission test.

NR 422.144(7)(c)(c) The VOC content of heatset web, sheet-fed and cold set web letterpress inks and blanket or roller wash shall be determined by Method 24 of 40 CFR part 60, Appendix A, incorporated by reference in s. NR 484.04 (13).

NR 422.144(8)(a)(a) Existing sources.

NR 422.144(8)(a)2.2. The owner or operator of a heatset web letterpress printing press shall submit to the department, no later than July 1, 2012, written certification that the press is in compliance with the applicable requirements of subs. (4) and (5) and shall provide a demonstration of compliance in accordance with subs. (6) and (7). A compliance emission test performed in accordance with s. NR 439.07 no more than 2 years prior to the compliance deadline, which demonstrates compliance with sub. (4) (a), is acceptable as a demonstration of compliance in accordance with sub. (7).

NR 422.144(8)(b)(b) New sources.

NR 422.144(8)(b)1.1. The owner or operator of a heatset web letterpress printing press which is installed after May 1, 2012 shall perform a compliance emission test within 180 days after installation of the press and shall submit to the department no later than 60 days after the test written certification that the press is in compliance with the applicable requirements of subs. (4) and (5) and a demonstration of compliance in accordance with subs. (6) and (7).

NR 422.144(8)(b)2.2. The owner or operator of any letterpress printing press, other than a heatset web press, which is installed after May 1, 2012 shall submit to the department, no later than 180 days after installation of the press, written certification that the press is in compliance with the applicable requirements of subs. (4) and (5) and a demonstration of compliance in accordance with subs. (6) and (7).

NR 422.145(1)(a)(a) Subsections (2), (3), and (4) apply to all screen printing units at screen printing facilities that are either of the following:

NR 422.145(1)(a)1.1. Located in the county of Kenosha, Milwaukee, Ozaukee, Racine, Washington, or Waukesha and which have maximum theoretical emissions of VOCs from all screen printing units at the facility equal to or greater than 25 tons per year.

NR 422.145(1)(a)2.2. Located in the county of Kewaunee, Manitowoc, or Sheboygan and which have maximum theoretical emissions of VOCs from all screen printing units at the facility equal to or greater than 100 tons per year.
