Q-2, r. 35.5 - Regulation respecting landfill methane reclamation and destruction projects eligible for the issuance of offset credits

Section 27 Disposition versions

2021-07-15

27. Every landfill gas flow meter and CH4 analyzer used for quantification purposes pursuant to this Chapter must be maintained, cleaned and inspected as specified in the project’s monitoring plan and at the minimum maintenance, cleaning and inspection frequency specified by the manufacturer.

In addition, not more than 3 months before the end date of the reporting period for which quantification is carried out, the promoter must

(1)  have the accuracy of every flow meter used verified by a qualified person. The person must, for that purpose, use a Type L Pitot tube or a reference flow meter with a valid calibration certificate issued by the manufacturer or by a third party certified for that purpose, and compare the values obtained using those instruments with the values measured by the flow meter used for the project; and

(2)  for every CH4 analyzer used, either

(a)  have the accuracy of the CH4 analyzer verified by a qualified person. The person must, for that purpose, use a reference device with a valid calibration certificate issued by the manufacturer or by a third person certified for that purpose, and compare the values obtained using those instruments with the values measured by the CH4 analyzer used for the project; or

(b)  have the CH4 analyzer calibrated by the manufacturer or by a third party certified for that purpose by the manufacturer.

The promoter must also have the CH4 analyzer calibrated at the frequency specified by the manufacturer or, if that frequency is greater than 5 years, every 5 years.

The verification of the accuracy of flow meters and CH4 analyzers performed in accordance with the second paragraph must determine if the relative error in the reading of volumetric flow or CH4 concentration is within a +/-5% range from the reference value calculated using the following equation:

Relative error (%)	=	Mproject inst – Mreference inst	×	100
		Mproject inst

Where:

Relative error = Percentage difference between the measurements of the volumetric flow or CH4 concentration of landfill gas by project instruments compared to the reference instruments;

Mproject inst = Measurement instruments for the project, being the volumetric flow of landfill gas measured by the flow meter for the project or the CH4 concentration in the landfill gas by the CH4 analyzer for the project;

Mreference inst = Measurement made by reference instruments, being the volumetric flow of landfill gas measured by a reference flow meter or Type L Pitot tube, or the measurement of the CH4 concentration in the landfill gas by a reference CH4 analyzer.
