Ci = Organic concentration in ppm, dry basis, of compound i in the vent gas, determined by Method 18
MWi = Molecular weight of organic compound i in the vent gas, kg/kg-mol
0.0416 = Conversion factor for molar volume, kg-mol/m3 (at 293 K and 760 mm Hg)
10-6 = Conversion from ppm
Eh = (Q)(C)(MW)(0.0416)(10-6)
where:
Eh = Total organic mass flow rate, kg/h
Q = Volumetric flow rate of gases entering or exiting control device, as determined by Method 2, dscm/h;
C = Organic concentration in ppm, dry basis, as determined by Method 25A
MW = Molecular weight of propane, 44
0.0416 = Conversion factor for molar volume, kg-mol/m3 (at 293 K and 760 mm Hg)
10 -6 = Conversion from ppm.
NR 664.1034(3)(a)5.5. Determine the annual total organic emission rate by the following equation: where:
EA = Total organic mass emission rate, kg/y
Eh = Total organic mass flow rate for the process vent, kg/h
H = Total annual hours of operations for the affected unit, h
NR 664.1034(3)(a)6.6. Determine total organic emissions from all affected process vents at the facility by summing the hourly total organic mass emission rates (Eh, determined in subd. 4.) and by summing the annual total organic mass emission rates (EA, determined in subd. 5.) for all affected process vents at the facility. NR 664.1034(3)(b)(b) Record the process information as may be necessary to determine the conditions of the performance tests. Operations during periods of startup, shutdown and malfunction may not constitute representative conditions for the purpose of a performance test. NR 664.1034(3)(c)(c) For an affected facility, provide, or cause to be provided, all of the following performance testing facilities: NR 664.1034(3)(d)(d) For the purpose of making compliance determinations, use the time-weighted average of the results of the 3 runs. In the event that a sample is accidentally lost or conditions occur in which one of the 3 runs must be discontinued because of forced shutdown, failure of an irreplaceable portion of the sample train, extreme meteorological conditions or other circumstances beyond the owner or operator’s control, compliance may, upon the department’s approval, be determined using the average of the results of the 2 other runs. NR 664.1034(4)(4) To show that a process vent associated with a hazardous waste distillation, fractionation, thin-film evaporation, solvent extraction or air or steam stripping operation is not subject to this subchapter, the owner or operator shall make an initial determination that the time-weighted, annual average total organic concentration of the waste managed by the waste management unit is less than 10 ppmw using one of the following 2 methods: NR 664.1034(4)(a)(a) Direct measurement of the organic concentration of the waste. This method requires all of the following:
