Where:
Cc = Concentration of total hydrocarbons, total organic HAP, vinyl chloride, or hydrogen chloride corrected to 3-percent oxygen, dry basis, parts per million by volume.
Cm = Concentration of total hydrocarbons, total organic HAP, vinyl chloride, or hydrogen chloride, dry basis, parts per million by volume.
%O2d = Concentration of oxygen, dry basis, percentage by volume.
Where:
Ca = Corrected outlet concentration of HAP, dry basis, parts per million by volume (ppmv).
Cm = Actual concentration of HAP measured at control device outlet, dry basis, ppmv.
Qa = Total volumetric flow rate of all gas streams vented to the control device, except supplemental gases.
Qs = total volumetric flow rate of supplemental gases.
