Fluidized catalytic cracking units, additives
 8. (1) No person shall operate a fluidized catalytic cracking unit at the IOL-Nanticoke facility, the IOL-Sarnia facility or the Shell facility unless the following ratio is equal to or greater than the ratio determined under subsection (3): A ÷ B where, “A” is the amount of sulphur dioxide-reducing additives, in kilograms, added to the fluidized catalytic cracking unit in a calendar day, and “B” is the amount of fresh catalyst, in kilograms, added to the fluidized catalytic cracking unit in a calendar day. O. Reg. 89/22, s. 8 (1). Note: On January 1, 2027, subsection 8 (1) of the Regulation is amended by striking out “the IOL-Nanticoke facility, the IOL-Sarnia facility or”. (See: O. Reg. 89/22, s. 8 (2)) (2) Despite subsection (1), if notice has been given under subsection 10 (2) in respect of an updated ratio, no person shall operate the fluidized catalytic cracking unit that is the subject of the notice unless the ratio set out in subsection (1) is equal to or greater than the ratio determined under subsection 10 (1) in respect of the unit. O. Reg. 89/22, s. 8 (1). (3) The ratio mentioned in subsection (1) shall be determined in respect of each fluidized catalytic cracking unit at the petroleum facility using the following method: 1. Determine the rate at which fresh catalyst is added to the fluidized catalytic cracking unit. 2. Estimate the concentration of sulphur dioxide discharged from the unit when no sulphur dioxide-reducing additives are added to the unit, expressed as parts per million by volume of sulphur dioxide, averaged over a 365-day period. 3. Determine the rate at which sulphur dioxide-reducing additives would need to be added to the unit to, i. reduce the concentration estimated under paragraph 2 to 75 parts per million or less, or ii. reduce the concentration estimated under paragraph 2 by, A. 35 per cent, in respect of a fluidized catalytic cracking unit at the IOL-Nanticoke facility and the Shell facility, and B. 95 per cent, in respect of a fluidized catalytic cracking unit at the IOL-Sarnia facility. 4. Calculate the following ratio: A ÷ B where, “A” is the rate determined under paragraph 3 in respect of sulphur dioxide-reducing additives, and “B” is the rate determined under paragraph 1, in respect of fresh catalyst. O. Reg. 89/22, s. 8 (1). (4) A rate determined under subsection (3) shall be expressed as kilograms per day. O. Reg. 89/22, s. 8 (1). (5) On the day this section comes into force, a person to whom subsection (1) applies shall notify the Director, in writing, of each ratio determined under paragraph 4 of subsection (3) and shall include in the notice, for each ratio, (a) an indication of whether the ratio is based on the reduction set out in subparagraph 3 i or ii of subsection (3); and (b) the calculations and any assumptions used to determine the ratio, including any measurements taken and any information relied upon from the supplier of the sulphur dioxide-reducing additives. O. Reg. 89/22, s. 8 (1). (6) A notice given under subsection (5) must be dated, signed and sealed by a licensed engineering practitioner and must set out the practitioner’s name and licence number, and the notice must be accompanied by a statement from the supplier of the sulphur dioxide-reducing additives indicating that the ratio determined under paragraph 4 of subsection (3) is sufficient to reduce the concentration of sulphur dioxide discharged from the fluidized catalytic cracking unit by the applicable amount set out in paragraph 3 of subsection (3). O. Reg. 89/22, s. 8 (1). (7) If a notice given under subsection (5) in respect of the IOL-Sarnia facility indicates that a ratio is based on the reduction set out in subparagraph 3 i of subsection (3), subsections (1) and (2) do not apply in respect of the fluidized catalytic cracking unit to which the ratio relates on and after July 1, 2024. O. Reg. 89/22, s. 8 (1).
