Vsi is the proportion of solids by volume in each coating (i) as received, NR 440.53(2)(b)25.25. Woi is the proportion of VOC by weight in each coating (i), as received, NR 440.53(3)(3) Standards for volatile organic compounds. On and after the date on which the initial performance test required by s. NR 440.08 is completed, no owner or operator subject to the provisions of this section may discharge or cause the discharge into the atmosphere from any affected facility VOC emissions in excess of: NR 440.53(3)(a)(a) 0.16 kilograms of VOC per liter of applied coating solids from each prime coat operation. NR 440.53(3)(b)(b) 1.40 kilograms of VOC per liter of applied coating solids from each guide coat operation. NR 440.53(3)(c)(c) 1.47 kilograms of VOC per liter of applied coating solids from each topcoat operation. NR 440.53(4)(b)(b) The owner or operator of an affected facility shall conduct an initial performance test in accordance with s. NR 440.08 (1), and thereafter for each calendar month for each affected facility according to the procedures in this subsection. NR 440.53(4)(c)(c) The owner or operator shall use the following procedures for determining the monthly volume weighted average mass of VOC emitted per volume of applied coating solids. NR 440.53(4)(c)1.1. The owner or operator shall use the following procedures for each affected facility which does not use a capture system and a control device to comply with the applicable emission limit specified under sub. (3). NR 440.53(4)(c)1.a.a. Calculate the volume weighted average mass of VOC per volume of applied coating solids for each calendar month for each affected facility. The owner or operator shall determine the composition of the coatings by formulation data supplied by the manufacturer of the coating or from data determined by an analysis of each coating, as received, by Method 24 of 40 CFR part 60, Appendix A, incorporated by reference in s. NR 440.17 (1). The department may require the owner or operator who uses formulation data supplied by the manufacturer of the coating to determine data used in the calculation of the VOC content of coatings by Method 24 or an equivalent or alternative method. The owner or operator shall determine from company records on a monthly basis the volume of coating consumed, as received, and the mass of solvent used for thinning purposes. The volume weighted average of the total mass of VOC per volume of coating solids used each calendar month shall be determined by the following procedures: 1) Calculate the mass of VOC used in each calendar month for each affected facility by the following equation where “n” is the total number of coatings used and “m” is the total number of VOC solvents used: (∑ Ldj Ddj will be zero if no VOC solvent is added to the coatings, as received.)
2) Calculate the total volume of coating solids used in each calendar month for each affected facility by the following equation where“n” is the total number of coatings used: 3) Select the appropriate transfer efficiency (T) from the following tables for each surface coating operation:
Table 1 - Transfer Efficiencies
The values in the table above represent an overall system efficiency which includes a total capture of purge. If a spray system uses line purging after each vehicle and does not collect any of the purge material, the following table shall be used:
