The equation used to adjust the parts per million by volume pollutant concentrations referenced on a dry basis to a specified oxygen percentage correction basis.

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.
