Continuous monitoring, parameters
 22. (1) On and after July 1, 2024, a person who discharges or causes or permits the discharge of sulphur dioxide into the air from a petroleum facility shall ensure that the following parameters are continuously measured in accordance with the approved continuous monitoring plan for the facility: 1. Subject to subsections (3) to (5), the concentration of sulphur dioxide in respect of, i. each thermal cracking unit at the petroleum facility, ii. each fluidized catalytic cracking unit and each Houdry catalytic cracking unit at the petroleum facility, iii. each carbon monoxide boiler at the petroleum facility in which gases from a cracking unit mentioned in subparagraph i are combusted before being discharged into the air, iv. each carbon monoxide boiler at the petroleum facility in which gases from a cracking unit mentioned in subparagraph ii are combusted before being discharged into the air, v. each sulphur recovery unit at the petroleum facility that is associated with an incinerator, vi. each general combustion device at the petroleum facility indicated in the plan for the purposes of subparagraph 2 i of subsection 20 (1), and vii. each air pollution control device at the petroleum facility into which sulphur dioxide from two or more sources of contaminant mentioned in subparagraphs i to vi is conveyed. 2. The concentration of total reduced sulphur, measured as a concentration of sulphur dioxide, in respect of each sulphur recovery unit at the petroleum facility that is not associated with an incinerator. 3. The concentration of hydrogen sulphide, measured as a concentration of sulphur dioxide, in respect of each sulphur recovery unit at the petroleum facility that is not associated with an incinerator. 4. The concentration of oxygen gas in the air/oxygen mixture supplied to the Claus burner of each sulphur recovery unit at the petroleum facility in respect of which the criteria set out in subsection 5 (1) are met. 5. The concentration of hydrogen sulphide in fuel gas conveyed to, i. each flare at the petroleum facility, ii. each carbon monoxide boiler at the petroleum facility that is associated with a cracking unit mentioned in subparagraph 1 i or ii, and iii. each general combustion device at the petroleum facility indicated in the plan for the purposes of subparagraph 2 ii of subsection 20 (1). 6. Any additional parameters, such as flow rate, required to determine the amount, in kilograms, of, i. sulphur dioxide discharged into the air from each source of contaminant and air pollution control device mentioned in paragraphs 1 and 5, and ii. total reduced sulphur discharged into the air from each sulphur recovery unit at the petroleum facility that is not associated with an incinerator. 7. The following parameters in respect of each flare at the petroleum facility: i. Whether the pilot flame is on or off. ii. Visible emissions from the flare. iii. Flare tip velocity. iv. Net heating value of the flare combustion zone gas. v. Net heating value dilution parameter. (2) The parameters set out in paragraphs 1 to 7 of subsection (1) shall be measured at each applicable measurement point set out in the approved continuous monitoring plan for the facility. (3) If gases from a cracking unit mentioned in subparagraph 1 i or ii of subsection (1) are combusted in a carbon monoxide boiler before being discharged into the air, the concentration of sulphur dioxide shall be measured in respect of the boiler instead of in respect of the cracking unit. (4) The concentration of sulphur dioxide from a sulphur recovery unit mentioned in subparagraph 1 v of subsection (1) shall be measured in respect of the incinerator instead of in respect of the sulphur recovery unit. (5) If sulphur dioxide from two or more sources of contaminant mentioned in subparagraphs 1 i to vi of subsection (1) is conveyed to a common air pollution control device, the concentration of sulphur dioxide shall be measured in respect of the air pollution control device instead of in respect of the individual sources of contaminant.
