If you control organic HAP on any individual web coating line or any group of web coating lines to demonstrate compliance with the emission limits in § 63.3320 by: | You must: |
(1) Limiting organic HAP or volatile matter content of coatings | Determine the organic HAP or volatile matter and coating solids content of coating materials according to procedures in paragraphs (c) and (d) of this section. If applicable, determine the mass of volatile matter retained in the coated web or otherwise not emitted to the atmosphere according to paragraph (g) of this section. |
(2) Using a capture and control system | (i) Initially, conduct a performance test for each capture and control system to determine: The destruction or removal efficiency of each control device other than solvent recovery according to § 63.3360(e) , and the capture efficiency of each capture system according to § 63.3360(f) . If applicable, determine the mass of volatile matter retained in the coated web or otherwise not emitted to the atmosphere according to § 63.3360(g) . |
(ii) Perform a periodic test once every 5 years for each thermal oxidizer to determine the destruction or removal efficiency according to § 63.3360(e) . If applicable, determine the mass of volatile matter retained in the coated web or otherwise not emitted to the atmosphere according to § 63.3360(g) . | |
(iii) Either perform a periodic test once every 5 years for each catalytic oxidizer to determine the destruction or removal efficiency according to § 63.3360(e) OR perform a catalyst activity test annually on each catalytic oxidizer to ensure that the catalyst is performing properly according to § 63.3360(e)(3)(ii)(D)(1) . If applicable, determine the mass of volatile matter retained in the coated web or otherwise not emitted to the atmosphere according to § 63.3360(g) . |
Where:
Mf = Total organic volatile matter mass flow rate, kilograms (kg)/hour (h).
Qsd = Volumetric flow rate of gases entering or exiting the control device, as determined according to paragraph (e)(1)(ii) of this section, dry standard cubic meters (dscm)/h.
Cc = Concentration of organic compounds as carbon, ppmv.
12.0 = Molecular weight of carbon.
0.0416 = Conversion factor for molar volume, kg-moles per cubic meter (mol/m3) (@293 Kelvin (K) and 760 millimeters of mercury (mmHg)).
Where:
E = Organic volatile matter control efficiency of the control device, percent.
Mfi = Organic volatile matter mass flow rate at the inlet to the control device, kg/h.
Mfo = Organic volatile matter mass flow rate at the outlet of the control device, kg/h.
Where:
Mvret = Mass of volatile matter retained in the coated web after curing or drying, or otherwise not emitted to the atmosphere, kg.
Cvi = Volatile organic content of coating material, i, expressed as a mass fraction, kg/kg.
Mi = Mass of as-purchased coating material, i, applied in a month, kg.
q = Number of different materials added to the coating material.
Cvij = Volatile organic content of material, j, added to as-purchased coating material, i, expressed as a mass fraction, kg/kg.
Mij = Mass of material, j, added to as-purchased coating material, i, in a month, kg.
EFi = Volatile organic matter site- and product-specific emission factor (three-run average determined from performance testing, evaluated as proportion of mass volatile organics emitted to mass of volatile organics in the coatings used during the performance test).
