NR 440.72(2)(a)9.9. “Plastic parts” means panels, housings, bases, covers, and other business machine components formed of synthetic polymers. NR 440.72(2)(a)10.10. “Prime coat” means the initial coat applied to a part when more than one coating is applied, not including conductive sensitizers or electromagnetic interference/radio frequency interference shielding coatings. NR 440.72(2)(a)11.11. “Spray booth” means the structure housing automatic or manual spray application equipment where a coating is applied to plastic parts for business machines. NR 440.72(2)(a)12.12. “Texture coat” means the rough coat that is characterized by discrete, raised spots on the exterior surface of the part. This definition does not include conductive sensitizers or EMI/RFI shielded coatings. NR 440.72(2)(a)13.13. “Touch-up coat” means the coat applied to correct any imperfections in the finish after color or texture coats have been applied. This definition does not include conductive sensitizers or EMI/RFI shielded coatings. NR 440.72(2)(a)14.14. “Transfer efficiency” means the ratio of the amount of coating solids deposited onto the surface of a plastic business machine part to the total amount of coating solids used. NR 440.72(2)(a)15.15. “VOC emissions” means the mass of VOCs emitted from the surface coating of plastic parts for business machines expressed as kilograms of VOCs per liter of coating solids applied (i.e., deposited on the surface). NR 440.72(2)(b)(b) As used in this section, all symbols not defined in this subsection have the meanings given them in s. NR 440.03. Dc = density of each coating as received (kilograms per liter)
Dd = density of each diluent VOC (kilograms per liter)
Lc = the volume to each coating consumed, as received (liters)
Ld = the volume of each diluent VOC added to coatings (liters)
Ls = the volume of coating solids consumed (liters)
Md = the mass of diluent VOCs consumed (kilograms)
Mo = the mass of VOCs in coatings consumed, as received (kilograms)
N = the volume-weighted average mass of VOC emissions to the atmosphere per unit volume of coating solids applied (kilograms per liter)
T = the transfer efficiency for each type of application equipment used at a coating operation (fraction)
Tavg = the volume weighted average transfer efficiency for a coating operation (fraction)
Vs = the proportion of solids in each coating, as received (fraction by volume)
Wo = the proportion of VOCs in each coating, as received (fraction by weight)
NR 440.72(3)(a)(a) Each owner or operator of any affected facility which is subject to the requirements of this section shall comply with the emission limitations set forth in this subsection on and after the date on which the initial performance test, required by s. NR 440.08 and sub. (4) is completed, but not later than 60 days after achieving the maximum production rate at which the affected facility will be operated, or 180 days after the initial startup, which ever date comes first. No affected facility may cause the discharge into the atmosphere in excess of: NR 440.72(3)(a)1.1. 1.5 kilograms of VOCs per liter of coating solids applied from prime coating of plastic parts for business machines. NR 440.72(3)(a)2.2. 1.5 kilograms of VOCs per liter of coating solids applied from color coating of plastic parts for business machines. NR 440.72(3)(a)3.3. 2.3 kilograms of VOCs per liter of coating solids applied from texture coating of plastic parts for business machines. NR 440.72(3)(a)4.4. 2.3 kilograms of VOCs per liter of coatings solids applied from touch-up coating of plastic parts for business machines. NR 440.72(3)(b)(b) All VOC emissions that are caused by coating applied in each affected facility, regardless of the actual point of discharge of emissions into the atmosphere, shall be included in determining compliance with the emission limits in par. (a). NR 440.72(4)(4) Performance tests and compliance provisions.
