67.3.(Replaced, O.C. 501-2011)Correction: The concentration standards prescribed in sections 67.1 and 67.2 are given on a dry basis under standard conditions corrected at 11% oxygen by the following equation:
E = Ea x (21 - A) ________ (21 - B)
where E is the corrected emission;
Ea is the emission on a dry basis uncorrected;
A is the base oxygen percentage;
B is the oxygen percentage in the combustion gases at the sampling point.
In the case of an incinerator using oxygen-enriched air, the correction factor must be calculated in accordance with the additional oxygen supply.
