(Equation 5)
where:
Hs is the monthly average, as-applied, organic HAP to coating solids ratio, kg of organic HAP per kg of coating solids applied
p is the number of different coating materials applied in a month
Chi is the organic HAP content of coating material, i, as-purchased, expressed as a mass fraction, kg/kg
Mi is the mass of as-purchased coating material, i, applied in a month, kg
q is the number of different materials added to the coating material
Chij is the organic HAP content of material, j, added to as-purchased coating material, i, expressed as a mass fraction, kg/kg
Mij is the mass of material, j, added to as-purchased coating material, i, in a month, kg
Mvret is the mass of volatile matter retained in the coated web after curing or drying, or otherwise not emitted to the atmosphere, kg. The value of this term will be zero in all cases except where you choose to take into account the volatile matter retained in the coated web or otherwise not emitted to the atmosphere for the compliance demonstration procedures in this section.
Csi is the coating solids content of coating material, i, expressed as a mass fraction, kg/kg
Csij is the coating solids content of material, j, added to as-purchased coating material, i, expressed as a mass-fraction, kg/kg
NR 466.25(3)(e)1.1. The organic HAP content of each coating material as-applied at an existing affected source is no more than 0.04 kg of organic HAP per kg of coating material or 0.2 kg of organic HAP per kg of coating solids, and the organic HAP content of each coating material as-applied at a new affected source contains no more than 0.016 kg of organic HAP per kg of coating material or 0.08 kg of organic HAP per kg of coating solids. NR 466.25(3)(e)2.2. The monthly average organic HAP content of all as-applied coating materials at an existing affected source are no more than 0.04 kg of organic HAP per kg of coating material or 0.2 kg of organic HAP per kg of coating solids, and the monthly average organic HAP content of all as-applied coating materials at a new affected source is no more than 0.016 kg of organic HAP per kg of coating material or 0.08 kg of organic HAP per kg of coating solids. NR 466.25(4)(4) Monthly allowable organic hap applied. Demonstrate that the total monthly organic HAP applied as determined by Equation 6 is less than the calculated equivalent allowable organic HAP as determined by Equation 13a or b in sub. (12) (e): (Equation 6)
where:
Hm is the total monthly organic HAP applied, kg
p is the number of different coating materials applied in a month
Chi is the organic HAP content of coating material, i, as-purchased, expressed as a mass fraction, kg/kg
Mi is the mass of as-purchased coating material, i, applied in a month, kg
q is the number of different materials added to the coating material
Chij is the organic HAP content of material, j, added to as-purchased coating material, i, expressed as a mass fraction, kg/kg
Mij is the mass of material, j, added to as-purchased coating material, i, in a month, kg
Mvret is the mass of volatile matter retained in the coated web after curing or drying, or otherwise not emitted to the atmosphere, kg. The value of this term will be zero in all cases except where you choose to take into account the volatile matter retained in the coated web or otherwise not emitted to the atmosphere for the compliance demonstration procedures in this section.
NR 466.25(5)(5) Capture and control to reduce emissions to no more than allowable limit. To reduce emissions to no more than the allowable limit in s. NR 466.23 (1) (b) 1., operate a capture system and control device and demonstrate an overall organic HAP control efficiency of at least 95% at an existing affected source and at least 98% at a new affected source for each month, or operate a capture system and oxidizer so that an outlet organic HAP concentration of no greater than 20 ppmv by compound on a dry basis is achieved as long as the capture efficiency is 100% as detailed in s. NR 466.23 (1) (b) 4. Unless one of the cases described in par. (a), (b) or (c) applies to the affected source, you shall either demonstrate compliance in accordance with the procedure in sub. (9) when emissions from the affected source are controlled by a solvent recovery device, or the procedure in sub. (11) when emissions are controlled by an oxidizer or demonstrate compliance for a web coating line by operating each capture system and each control device and continuous parameter monitoring according to the procedures in sub. (10). NR 466.25(5)(a)(a) If the affected source has only always-controlled work stations and operates more than one capture system or more than one control device, you shall demonstrate compliance in accordance with the provisions of either sub. (14) or (16).
