Q-2, r. 35.3.01 - Regulation respecting manure anaerobic digestion projects eligible for the issuance of offset credits

Section 34 Disposition versions

34. Every measurement instrument 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.

Not more than 3 months before the end date of the reporting period for which quantification is carried out, the promoter must, for all biogas flow meters, fixed or portable CH4 analyzers, charging scales or level detectors used for quantification purposes pursuant to this Chapter,

(1)  have the accuracy of every flow meter used verified by a qualified and independent 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 that device with the values measured by the flow meter used for the project; and

(2)  for every CH4 concentration analyzer, charging scale or level detector used, either

(a)  have the accuracy of the instrument verified by a qualified and independent 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 that device with the values measured by the instrument used for the project; or

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

The promoter must also have the instruments calibrated by the manufacturer or by a third party certified for that purpose by the manufacturer 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 charging scales, level detectors, flow meters and CH4 analyzers performed in accordance with subparagraph 2 of the second paragraph must determine if the relative error in the reading of the mass or volume of inputs, the volumetric flow or the CH4 concentration is within a +/-5% range from the reference value calculated using the following equation:

Equation 15: Calculation of the relative error of measurement instruments

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

Where:

Relative error = Percentage difference between the measurements of the mass or volume of inputs or the volumetric flow or CH4 concentration of biogas by the project instruments compared to the reference instruments;

Mproject inst = Measurement made by measurement instruments for the project, being the mass or volume of inputs measured by charging scales or level detectors, the volumetric flow of biogas measured by the flow meter for the project, or the CH4 concentration in the biogas measured by the CH4 analyzer for the project;

Mreference inst = Measurement made by reference instruments, being the mass or volume of inputs measured by the reference charging scales or level detectors, the volumetric flow of biogas measured by the reference flow meter or Type L Pitot tube, or the CH4 concentration in the landfill gas measured by the reference CH4 analyzer.
