Regulations Respecting Reduction in the Release of Methane and Certain Volatile Organic Compounds (Upstream Oil and Gas Sector)

Marginal note:Continuous monitoring devices

• 50 (1) The flow rate of emissions of hydrocarbon gas from vents referred to in paragraph 49(b) must be measured by means of a continuous monitoring device.

• Marginal note:Requirements

  (2) A continuous monitoring device must

  • (a) be calibrated in accordance with the manufacturer’s recommendations such that its measurements have a maximum margin of error of ±10%;

  • (b) be operated continuously, other than during periods when it is undergoing normal servicing or timely repairs; and

  • (c) be equipped with an alarm that is triggered when the applicable flow rate limit referred to in subsection (3) for the vents of the compressor is reached.

• Marginal note:Flow rate limit

  (3) The flow rate limit of emissions of hydrocarbon gas from the vents of a compressor is

  • (a) for a compressor that was installed before January 1, 2023,

    • (i) 0.68 standard m³/min, if the compressor has a rated brake power of greater than or equal to 5 MW, and

    • (ii) 0.34 standard m³/min, if the compressor has a rated brake power of less than 5 MW; and

  • (b) for a compressor that was installed on or after January 1, 2023, 0.14 standard m³/min.

• Marginal note:Corrective action

  (4) If the alarm is triggered, corrective action must be taken to reduce the flow rate to below or equal to the applicable flow rate limit, as demonstrated by the absence of an alarm when the compressor begins to operate following the taking of that action.
