where:
Ha is the monthly allowable organic HAP emissions, kg
p is the number of different coating materials applied in a month
Mi is the mass of as-purchased coating material, i, applied in a month, kg
Gi is the mass fraction of each coating material, i, which was applied at 20% by mass or greater coating solids content, on an as-applied basis, kg/kg
Csi is the coating solids content of coating material, i, expressed as a mass fraction, kg/kg
q is the number of different materials added to the coating material
MLj is the mass of non-coating-solids-containing coating material, j, added to coating-solids-containing coating materials which were applied at less than 20% by mass coating solids content, on an as-applied basis, in a month, kg

NR 466.25(14)(14) Combinations of capture and control. If you operate more than one capture system, more than one control device, one or more never-controlled work stations or one or more intermittently-controlled work stations, you shall calculate organic HAP emissions according to the procedures in pars. (a) to (d) and use the calculation procedures specified in par. (e) to convert the monitoring and other data into units of the selected control option in subs. (5) to (8). Use the procedures specified in par. (f) to demonstrate compliance. NR 466.25(14)(a)(a) Solvent recovery system using liquid-liquid material balance compliance demonstration. If you choose to comply by means of a liquid-liquid material balance for each solvent recovery system used to control one or more web coating lines, you shall determine the organic HAP emissions for the web coating lines controlled by the solvent recovery system in accordance with one of the following: NR 466.25(14)(a)1.1. Subsection (9) (a) 1. to 3. and 5. to 7., if the web coating lines controlled by the solvent recovery system have only always-controlled work stations. NR 466.25(14)(a)2.2. Subsections (9) (a) 2., 3., 5. and 6. and (15), if the web coating lines controlled by the solvent recovery system have one or more never-controlled or intermittently-controlled work stations. NR 466.25(14)(b)(b) Solvent recovery system using performance test compliance demonstration and CEMS. To demonstrate compliance through an initial test of capture efficiency, continuous monitoring of a capture system operating parameter and a CEMS on each solvent recovery system used to control one or more web coating lines, you shall do both of the following: NR 466.25(14)(b)1.1. For each capture system delivering emissions to that solvent recovery system, monitor the operating parameter established in accordance with s. NR 466.24 (2) (f) to ensure capture system efficiency. NR 466.25(14)(b)2.2. Determine the organic HAP emissions for the web coating lines served by each capture system delivering emissions to the solvent recovery system in accordance with one of the following: NR 466.25(14)(b)2.b.b. Subsections (9) (b) 1. to 3. and 6. and (15) if the web coating lines served by the capture and control system have one or more never-controlled or intermittently-controlled work stations. NR 466.25(14)(c)(c) Oxidizer. To demonstrate compliance through performance tests of capture efficiency and control device efficiency, continuous monitoring of capture system and CPMS for control device operating parameters for each oxidizer used to control emissions from one or more web coating lines, you shall do all of the following:
