Where:
Cadj = pollutant concentration adjusted to percent O2, dry basis, specified in applicable rule, in units of applicable standard (e.g., parts per million by volume);
Cmeas = pollutant concentration measured on a dry basis, in units of applicable standard;
20.9% = O2 concentration in air, percent;
%O2 rule = O2 basis for adjustment specified in applicable rule (e.g., 3.0% for boilers and process heaters) on a dry basis, percent; and
%O2 meas = O2 concentration measured simultaneous with pollutant concentration, percent.
