You must separately calculate the mass average organic HAP content of the materials used during the initial compliance period for each group of materials for which an emission limit is established in § 63.3090(c) and (d) or § 63.3091(c) and (d) . If every individual material used within a group of materials meets the emission limit for that group of materials, you may demonstrate compliance with that emission limit by documenting the name and the organic HAP content of each material used during the initial compliance period. If any individual material used within a group of materials exceeds the emission limit for that group of materials, you must determine the mass average organic HAP content according to the procedures of paragraph (d) of this section.
Where:
Cavg, as = Mass average organic HAP content of adhesives and sealer materials used, kg/kg.
Volas, j = Volume of adhesive or sealer material, j, used, liters.
Das, j = Density of adhesive or sealer material, j, used, kg per liter.
Was, j = Mass fraction of organic HAP in adhesive or sealer material, j, kg/kg.
r = Number of adhesive and sealer materials used.
Where:
Cavg, d = Mass average organic HAP content of deadener material used, kg/kg.
Vold, m = Volume of deadener material, m, used, liters.
Dd, m = Density of deadener material, m, used, kg per liter.
Wd, m = Mass fraction of organic HAP in deadener material, m, kg/kg.
s = Number of deadener materials used.
