Regulations Respecting Reduction in the Release of Methane and Certain Volatile Organic Compounds (Upstream Oil and Gas Sector) — 8.15
Period for repair 8.15 (1) When a fugitive emission is detected at an upstream oil and gas facility, whether as a result of an inspection or otherwise, the equipment component that is emitting the hydrocarbon gas must be repaired (a) if the repair can be carried out while the equipment component is operating, within the applicable period referred to in subsection (2) or (3); and (b) in any other case, before the end of the next planned shutdown of the facility. Repair — flow rate not determined (2) If the equipment component can be repaired while it is operating and the flow rate of the fugitive emission is not determined, the component must be repaired within 24 hours after the emission is detected. Repair — flow rate determined (3) If the equipment component can be repaired while it is operating and the flow rate of the fugitive emission is determined, the component must be repaired (a) in the case of a flow rate that is less than 1 kg/h, within 90 days after the day on which the emission is detected; (b) in the case of a flow rate that is 1 kg/h or more but less than 10 kg/h, within 30 days after the day on which the emission is detected; (c) in the case of a flow rate that is 10 kg/h or more but less than 100 kg/h, within seven days after the day on which the emission is detected; and (d) in the case of a flow rate that is 100 kg/h or more, within 24 hours after the emission is detected. Flow rate reduced (4) However, if a measure is taken that reduces the flow rate of the fugitive emission to less than 10 kg/h during the applicable repair period referred to in paragraph (3)(c) or (d), the repair must be completed within 30 days after the day on which the emission is detected. Volume of hydrocarbon gas (5) In subsections (6) and (7), a reference to a volume of hydrocarbon gas is a reference to that volume expressed in standard m 3 . Deferral of repair — low level emissions (6) Despite paragraphs (3)(a) and (b) and subsection (4), if the equipment component is emitting hydrocarbon gas at a flow rate of less than 10 kg/h, the repair of the equipment component may be deferred until the day on which the estimated total volume of fugitive emissions that, beginning on the day on which the fugitive emission is detected, would be emitted from that equipment component and from all other equipment components as of that day is equal to the volume of hydrocarbon gas that, if none of those equipment components were repaired, would be emitted during a temporary depressurization of the equipment or a pipeline conducted in order to carry out the repair. Repair — facility shutdown necessary (7) If the equipment component cannot be repaired while it is operating, the next planned shutdown of the upstream oil and gas facility must be scheduled no later than the day on which the estimated total volume of fugitive emissions that, beginning on the day on which the fugitive emission is detected, would be emitted from that equipment component and from all other equipment components as of that day is equal to the volume of hydrocarbon gas that, if none of those equipment components were repaired, would be emitted during a temporary depressurization of the equipment or a pipeline conducted in order to carry out the repair. Verification of repair (8) An equipment component is considered to be repaired when the fugitive emission is no longer detectable using a method that is capable of detecting hydrocarbon gas at a flow rate of 60 g/h or less or at a concentration of 500 ppmv or less.
