Mij is the mass of material, j, added to as-purchased coating material, i, in a month, kg
NR 466.25(9)(a)7.7. Calculate the organic HAP emitted during the month using Equation 8: where:
He is the total monthly organic HAP emitted, kg
Rv is the organic volatile matter collection and recovery efficiency, percent
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(9)(a)8.8. Calculate the organic HAP emission rate based on coating solids applied using Equation 9: where:
L is the mass of organic HAP emitted per mass of coating solids applied, kg/kg
He is the total monthly organic HAP emitted, kg
p is the number of different coating materials applied in a month
Csi is the coating solids content of coating material, i, 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
Csij is the coating solids 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
NR 466.25(9)(a)9.9. Calculate the organic HAP emission rate based on coating material applied using Equation 10: where:
S is the mass organic HAP emitted per mass of material applied, kg/kg
He is the total monthly organic HAP emitted, kg
