41J Determining the quantity of eligible biogas from a biogas source (QBG, El, g)

(1) The volume of eligible biogas sent to project biomethane facility m from biogas source facility g during a reporting period, QBG, El, g (in cubic metres), is worked out:

(a) if it is possible to measure QBG, El, g in accordance with the monitoring requirements—in accordance with the monitoring requirements; or

(b) if it is not possible to measure QBG, El, g in accordance with the monitoring requirements—in accordance with subsection (2).

Note: Measurement of QBG, El, g is possible if all biogas from a biogas source facility is eligible, or if eligible biogas is physically apportioned in such a way that permits direct measurement in accordance with the monitoring requirements.

(2) For paragraph (1)(b), the volume of eligible biogas sent to project biomethane facility m from biogas source facility g during a reporting period, QBG, El, g (in cubic metres) is worked out using the formula (equation 25):

EBg is the proportion of biogas sent to project biomethane facility m from biogas source facility g during a reporting period that is eligible biogas, expressed as a fraction, determined in accordance with subsection (3).

QBG, g is the volume of biogas sent to project biomethane facility m from biogas source facility g during the reporting period, in cubic metres, determined in accordance with the monitoring requirements.

(3) For subsection (2), the proportion of biogas sent to project biomethane facility m from biogas source facility g during a reporting period that is eligible biogas, EBg, expressed as a fraction, must be:

(a) determined using:

(i) the proportion of eligible biogas waste to biogas waste treated to produce biogas from biogas source facility g for a reporting period, by methane-producing capacity; or
(ii) the proportion of eligible biogas waste to biogas waste treated to produce biogas from biogas source facility g for a reporting period, by mass; or
(iii) another approach that can reasonably be expected to provide a fraction that accurately reflects the proportion of eligible biogas for biogas source facility g in a reporting period; and

(b) determined using an approach that can reasonably be expected to provide an accurate and conservative value for EBg; and

(c) determined based on data and calculations that are auditable and verifiable.

(4) If it is not possible to work out the volume of eligible biogas sent to project biomethane facility m from biogas source facility g during a reporting period, QBG, El, g (in cubic metres), in accordance with subsection (1), QBG, El, g is taken to be zero for the reporting period.
