NR 422.095(7)(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 422.095(7)(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 422.095(8) (8) Recordkeeping. In addition to the applicable recordkeeping requirements in s. NR 439.04, the owner or operator of any automobile refinishing operation 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 422.095(8)(a) (a) For each operation that is exempt under sub. (2) (f), the daily quantity in fluid ounces of VOC-containing aerosol product used for industrial cleaning operations.

NR 422.095(8)(b) (b) For each operation that is subject to sub. (7), the following information as appropriate:

NR 422.095(8)(b)1. 1. The name and identification of each cleaning material and the associated solvent cleaning activity.

NR 422.095(8)(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 422.095(8)(b)3. 3. For any operation subject to sub. (7) (d), the results of any testing conducted as required under sub. (7) (d).
