Regulations Respecting Reduction in the Release of Methane and Certain Volatile Organic Compounds (Upstream Oil and Gas Sector) — 16
 facility on the day specified in the notice provided under subsection 2.2(2); and (b) each update to its facility emission intensity and facility emission rate, the date of the update and the reason for it. Continuous operation 52 (1) An emission monitoring system must be operating at all times, except for any period during which all or part of the system is undergoing preventive maintenance. Preventive maintenance (2) The preventive maintenance must not be performed during any period in which an emission of hydrocarbon gas is planned or expected to occur at the upstream oil and gas facility. System Requirements Sensors and other equipment 53 (1) An emission monitoring system must meet the following requirements: (a) its sensors and other equipment must (i) be capable, under controlled laboratory conditions, of detecting hydrocarbon gas emissions that have a total flow rate of 1 kg/h or more, and (ii) be placed at locations where they can detect hydrocarbon gas emissions at the facility; (b) its sensors must take readings (i) in the case of a Type 1 facility, at least once every 15 minutes, and (ii) in the case of a Type 2 facility or an inactive facility, at least once every 12 hours; (c) it must record each reading taken under paragraph (b); and (d) it must generate an alert when the total flow rate of hydrocarbon gas emissions detected at the facility exceeds the facility emission rate by 1 kg/h or more. Calibration (2) All sensors and other equipment that constitute the emission monitoring system must be calibrated in accordance with the manufacturer’s recommendations such that their measurements have a maximum margin of error of ±20%. Inspection Annual inspection 53.1 (1) Subject to subsections (2) and (3), an annual inspection for hydrocarbon gas emissions at an upstream oil and gas facility must be conducted once per calendar year, with no less than 180 days having elapsed since the date of the last annual inspection, by an auditor who (a) is independent of the operator and owner of the facility that is to be inspected; and (b) has knowledge of and experience with emission detection instruments. Exception (2) An annual inspection is not required to be conducted at the upstream oil and gas facility in any calendar year in which an annual inspection is conducted at the facility under subsection 8.12(1). Exception (3) An annual inspection is not required to include the inspection of an equipment component if that inspection would pose a serious risk to human health or safety. Methodology (4) An annual inspection must be conducted using methods that, under standard conditions, provide a 90% or greater probability of detecting hydrocarbon gas emissions at the facility that have a total flow rate of 10 kg/h or more. Record — annual inspection (5) A record must be made that sets out the following information respecting each annual inspection: (a) its date and time; (b) the name and contact information of the auditor who conducted the inspection, along with the name and business address of their employer; (c) a description of the methodology and equipment used; (d) information respecting the calibration of each instrument used; (e) whether hydrocarbon gas emissions were detected; and (f) if hydrocarbon gas emissions were detected, (i) their total flow rate, expressed in kg/h, (ii) the unique identifier, if any, assigned to those emissions by the operator, and (iii) a list of the measures that were taken to reduce those emissions, if any. Emissions Period for emission reduction 53.2 (1) If the total flow rate of hydrocarbon gas emissions detected at an upstream oil and gas facility is higher than its facility emission rate by 1 kg/h or more, the total flow rate must be reduced to less than 1 kg/h above the facility emission rate as soon as feasible, but in any case, by no later than (a) if the total flow rate is higher than the facility emission rate by 1 kg/h or more, but less than 10 kg/h higher than that rate, 30 days after
