Continuous monitoring plan
 20. (1) No later than eight months after the day this section comes into force, a person who discharges or causes or permits the discharge of sulphur dioxide into the air from a petroleum facility shall submit a plan to the Director titled “Continuous Monitoring Plan” that sets out the following information: 1. For each sulphur recovery unit at the petroleum facility, an indication of whether an air/oxygen mixture is supplied to the Claus burner in the unit and, if so, an indication of whether the concentration of the oxygen in the air/oxygen mixture will be measured. 2.   For each general combustion device at the petroleum facility, an indication of which one of the following parameters will be measured: i. The concentration of sulphur dioxide discharged into the air from the general combustion device. ii. The concentration of hydrogen sulphide in fuel gas conveyed to the general combustion device. 3. For each flare at the petroleum facility, an indication of whether the flare tip velocity will be calculated and whether perimeter assist air is used. 4. A description of how each parameter required to be measured under section 22 will be continuously measured, including an identification of each measurement point. 5. The methodology that will be used to determine, from the parameters measured under section 22, the amounts of sulphur dioxide and total reduced sulphur discharged into the air mentioned in paragraph 6 of subsection 22 (1), including sample calculations and an explanation of any assumptions made. (2) Despite paragraph 4 of subsection (1), a measurement point is not required to be identified in respect of the concentration of hydrogen sulphide in fuel gas conveyed to a flare or general combustion device if, instead, the plan includes evidence that the concentration of hydrogen sulphide in the fuel gas conveyed to the flare or general combustion device will always be less than five parts per million by volume. (3) Each measurement point shall be located at a point that ensures that, (a) the measurement can be attributed to a particular source of contaminant or to a particular air pollution control device, as the case may be; and (b) the measurement reflects, as applicable, (i) the concentration or amount of contaminant being discharged into the air, or (ii) the concentration of hydrogen sulphide in the fuel gas being conveyed to a flare or general combustion device. (4) If, after a plan is submitted under subsection (1), one or more of the following changes are proposed in respect of a petroleum facility, the person responsible for submitting the plan shall update and resubmit it and shall not operate the new or modified thing before receiving a notice from the Director under subsection (6): 1. A modification to, i. an air pollution control device, ii. a flare, iii. a fluidized catalytic cracking unit, iv. a general combustion device, v. a Houdry catalytic cracking unit, vi. a sulphur recovery unit, or vii. a thermal cracking unit. 2. The addition of any of the things mentioned in paragraph 1 to the petroleum facility. (5) A plan submitted under subsection (1) or updated and resubmitted under subsection (4) must be dated, signed and sealed by a licensed engineering practitioner and must set out the practitioner’s name and licence number. (6) The Director shall give written notice to a person who submitted a plan under subsection (1) or resubmitted a plan under subsection (4) if the Director is of the opinion that following the plan would result in, (a) the accurate measurement of the parameters required to be measured under section 22; and (b) the accurate determination of the amounts of sulphur dioxide and total reduced sulphur discharged into the air mentioned in paragraph 6 of subsection 22 (1). (7) The Director may, by written notice, require a person who submitted a plan under subsection (1) or resubmitted a plan under subsection (4) to submit any specifications, technical reports or other information reasonably necessary for the Director to review the plan. (8) Before the Director gives a person a notice under subsection (7), the Director shall give the person a draft of the notice and an opportunity to make written submissions to the Director during the period that ends 30 days after the draft is given.
