NR 465.47(2)(d) (d) Determine the volume of each material used. Determine the volume in liters (gallons) of each coating, thinner, other additive, and cleaning material used during each month by measurement or usage records. If you purchase materials or monitor consumption by weight instead of volume, you do not need to determine the volume of each material used. Instead, you may use the material weight in place of the combined terms for density and volume in Equations 1A, 1B and 1C of this subsection.

NR 465.47(2)(e) (e) Calculate the mass of organic HAP emissions.

NR 465.47(2)(e)1. 1. The mass of organic HAP emissions is the combined mass of organic HAP contained in all coatings, thinners, other additives and cleaning materials used during each month minus the organic HAP in certain waste materials. Calculate the mass of organic HAP emissions using the following equations and the procedures in subd. 2. if applicable:

(Equation 1)

where:

He is the total mass of organic HAP emissions during the month, kg (lb)

A is the total mass of organic HAP in the coatings used during the month, kg (lb), as calculated in Equation 1A of this subsection

B is the total mass of organic HAP in the thinners and other additives used during the month, kg (lb), as calculated in Equation 1B of this subsection

C is the total mass of organic HAP in the cleaning materials used during the month, kg (lb), as calculated in Equation 1C of this subsection

Rw is the total mass of organic HAP in waste materials sent or designated for shipment to a hazardous waste TSDF for treatment or disposal during the month, kg (lb), determined according to subd. 2. You may assign a value of zero to RW if you do not wish to use this allowance.

where:

A is the total mass of organic HAP in the coatings used during the month, kg (lb)

Volc,i is the total volume of coating i, used during the month, liters (gallons)

Dc,i is the density of coating i, kg (lb) of coating per liter (gallon) of coating

Wc,i is the mass fraction of organic HAP in coating i, kg (lb) of organic HAP per kg (lb) of coating. For reactive adhesives, use the mass fraction of organic HAP that is emitted as determined using the method in 40 CFR part 63, Subpart PPPP, Appendix A, incorporated by reference in s. NR 484.04 (24r).

m is the number of different coatings used during the month

Volt,j is the total volume of thinner or other additive j, used during the month, liters (gallons)

Dt,j is the density of thinner or other additive j, kg per liter (lb per gallon)

Wt,j is the mass fraction of organic HAP in thinner or other additive j, kg (lb) of organic HAP per kg (lb) of thinner or other additive. For reactive adhesives, use the mass fraction of organic HAP that is emitted as determined using the method in 40 CFR part 63, Subpart PPPP, Appendix A, incorporated by reference in s.
