### Q-2, r. 19 - Regulation respecting the landfilling and incineration of residual materials

131. The measurements taken to monitor compliance with the limit values set out in section 130 are expressed as units of mass per cubic metre of dry combustion gas, at a reference temperature of 25 °C and pressure of 101.3 kPa, corrected to 11% oxygen according to the following formula:
E = Ea x (9.9 / (20.9 -A))
where
“E” is the corrected concentration;
“Ea” is the dry concentration at the above temperature and pressure; and
“A” is the percentage of oxygen, on a dry basis, in the combustion gases at the sampling point.
