NR 422.145(2m)(d)1. 1. The emission control system has a minimum overall emission reduction efficiency of 85% for VOC emissions, as determined in accordance with s. NR 439.06 (3) (am).

NR 422.145(2m)(d)2. 2. The emission control system has a minimum VOC capture efficiency of 90% and an output of VOC emissions of less than 50 ppm calculated as carbon, not including methane and ethane, with no dilution, as determined in accordance with s. NR 439.06 (3) (a).

NR 422.145(2m)(e) (e) General prohibitions. The owner or operator of a facility may not atomize any solvent or solvent solution unless the resulting VOC emissions are controlled by an air pollution control system that meets one of the requirements of par. (d).

NR 422.145(2m)(f) (f) Alternative compliance option. In lieu of complying with the requirements in par. (a), the owner or operator of a facility may use solvents or solvent solutions for industrial cleaning operations which have a VOC composite partial vapor pressure of less than or equal to 8 mm of Hg at 20°C.

NR 422.145(3) (3) Compliance deadline. The owner or operator of a screen printing unit subject to this section on which construction or modification commenced before July 1, 1994 shall achieve final compliance with the emission limitations of sub. (2) not later than May 31, 1995. Any source which is subject to this section and on which construction or modification commenced on or after July 1, 1994 shall meet the emission limitations of sub. (2) upon startup.

NR 422.145(4) (4) Recordkeeping. In addition to the applicable recordkeeping requirements in s. NR 439.04, the owner or operator of any screen printing facility 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 422.145(4)(a) (a) For each operation that is exempt under sub. (1m) (c), the daily quantity in fluid ounces of VOC-containing aerosol product used for industrial cleaning operations.

NR 422.145(4)(b) (b) For each operation that is subject to sub. (2m), the following information as appropriate:

NR 422.145(4)(b)1. 1. The name and identification of each cleaning material and the associated solvent cleaning activity.

NR 422.145(4)(b)2. 2. The VOC content of each cleaning material, in pounds per gallon of material, as employed or the VOC composite partial vapor pressure of the solvents or solvent solutions used in industrial cleaning operations.

NR 422.145(4)(b)3. 3. For any operation subject to sub. (2m) (d), the results of any testing conducted as required under sub. (2m) (d).
