Multi-Sector Air Pollutants Regulations (SOR/2016-151)

Marginal note:Invalid emissions check — temperature

• 90 (1) If there is a difference of more than 3°C between any two NO cell temperatures that are recorded in accordance with subsection 88(2), the emissions check in question and any concentration that is determined in accordance with section 89 are invalid.

• Marginal note:Invalid emissions check — cell measuring range

  (2) If any reading taken of an electrochemical cell’s response, or recording that is made of the average of the responses of that cell, in accordance with subsection 88(1) during an emissions check with an analyzer to determine a concentration in accordance with section 89 is outside the measuring range for that cell specified by the analyzer’s manufacturer,

  • (a) the emissions check and any concentration that is determined in accordance with that section are invalid; and

  • (b) no emissions check that is conducted with the analyzer is valid until

    • (i) a sequence of calibration error checks on its cells is conducted for which each calibration error check meets the requirements of subsection 83(6), and

    • (ii) a determination — based on the readings taken during that sequence — of at most 5% is made in accordance with subsections 84(2) and (3) of the CO interference response and of the NO interference response, respectively.
