Hsi is the as-applied, organic HAP to coating solids ratio of coating material, i

Cahi is the monthly average, as-applied, organic HAP content of coating material, i, expressed as a mass fraction, kg/kg

Casi is the monthly average, as-applied, coating solids content of coating material, i, expressed as a mass fraction, kg/kg

NR 466.25(3)(c)(c) Monthly average organic HAP content of all coating materials as-applied is less than the mass percent limit in s. NR 466.23 (1) (b) 2. Demonstrate that the monthly average as-applied organic HAP content of all coating materials applied at an existing affected source is less than 0.04 kg organic HAP per kg of coating material applied, and all coating materials applied at a new affected source are less than 0.016 kg organic HAP per kg of coating material applied, as determined by Equation 4:

(Equation 4)

where:

HL is the monthly average, as-applied, organic HAP content of all coating materials applied, expressed as kg organic HAP per kg of coating material 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.

NR 466.25(3)(d)(d) Monthly average organic HAP content of all coating materials as-applied is less than the mass fraction of coating solids limit in s. NR 466.23 (1) (b) 3. Demonstrate that the monthly average as-applied organic HAP content on the basis of coating solids applied of all coating materials applied at an existing affected source is less than 0.20 kg of organic HAP per kg of coating solids applied, and all coating materials applied at a new affected source are less than 0.08 kg of organic HAP per kg of coating solids applied, as determined by Equation 5:
