NR 664.1034(3)(a)3.3. Each performance test shall consist of 3 separate runs; conduct each run for at least one hour under the conditions that exist when the hazardous waste management unit is operating at the highest load or capacity level reasonably expected to occur. For the purpose of determining total organic compound concentrations and mass flow rates, average the results of all runs. Compute the average on a time-weighted basis.
NR 664.1034(3)(a)4.4. Determine total organic mass flow rates by the following equation:

where:
Eh = Total organic mass flow rate, kg/h
Q2sd = Volumetric flow rate of gases entering or exiting control device, determined by Method 2, dscm/h
n = Number of organic compounds in the vent gas
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
NR 664.1034(3)(a)4.b.b. For sources using Method 25A.

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.
