 6. (1) On or before March 31, 2019, a person who discharges or causes or permits the discharge of sulphur dioxide from a petroleum facility shall submit a plan to the Director titled “Sulphur Dioxide Emissions Calculation Plan” that sets out the following information: 1. Subject to subsection (2), the method the facility intends to use to calculate the amount of sulphur dioxide discharged from each piece of acid gas combustion equipment at the facility. 2. Each assumption that will be made when calculating an amount of sulphur dioxide under paragraph 1. 3. The frequency at which the facility intends to calculate the amount referred to in paragraph 1, which must be at least hourly and is only required when sulphur dioxide is being discharged from the acid gas combustion equipment when the sulphur recovery unit fails to operate in a normal manner. Note: On July 1, 2024, subsection 6 (1) of the Regulation is revoked. (See: O. Reg. 89/22, s. 6 (1)) (2) The method referred to in paragraph 1 of subsection (1) must assume a combustion efficiency of a flare of 98 per cent. Note: On July 1, 2024, subsection 6 (2) of the Regulation is revoked. (See: O. Reg. 89/22, s. 6 (1)) (3) From July 1, 2019 until the first day a continuous emissions monitoring system is installed and operated at the petroleum facility in accordance with subsection 7 (1), the person referred to in subsection (1) of this section shall calculate the following information in accordance with a Sulphur Dioxide Emissions Calculation Plan submitted under that subsection that, in the opinion of the Director, would accurately predict the amount of sulphur dioxide discharged from each piece of acid gas combustion equipment at the facility: 1. The amount of sulphur dioxide discharged from each piece of acid gas combustion equipment at the facility. 2. After making each calculation referred to in paragraph 1, the sum of the calculations required, in accordance with paragraph 3 of subsection (1), to be made in the preceding 24-hour period with respect to all acid gas combustion equipment at the facility.
