24  Methane sent to combustion device
 (1) Methane sent to a combustion device h during a particular period may be worked out using:
 (a) equation 8; or
 (b) equation 9; or
 (c) equation 10 (if applicable).

Option 1—using landfill gas sent to combustion device
 (2) Using the volume of the landfill gas sent to the combustion device (QLFG,h), the methane sent to the combustion device during the period is worked out using the formula (equation 8):
where:
MSent,h means the methane sent to the combustion device h during the period, in cubic metres.
QLFG,h means the landfill gas sent to the combustion device h during the period, in cubic metres, worked out in accordance with the monitoring requirements.
W LFG,CH4 means the proportion of the landfill gas that is methane, which is, at the election of the project proponent:
 (a) 0.42; or
 (b) worked out in accordance with the monitoring requirements; or
 (c) if the project is covered by subsection (2A)—set out in section 5.14C of the NGER (Measurement) Determination.
 (2A) The following projects are covered by this subsection:
 (a) a landfill gas project, other than a restarting flaring project, whose application under section 22 of the Act was made before 1 September 2020; or
 (b) a restarting flaring project that, when it was previously a landfill gas project, had an application under section 22 of the Act made before 1 September 2020.
 (3) If, at any time during which this determination is the applicable methodology for the project, the monitoring requirements are used to work out WLFG,CH4, then, the monitoring requirements must be used for that purpose for the remainder of the project.
 (4) Subsection (3) has effect subject to section 33.

Option 2—using energy content of landfill gas sent to combustion device
 (5) Using the energy content of the landfill gas sent to the combustion device (QEn,h), the methane sent to the combustion device during the period is worked out using the formula (equation 9):
where:
MSent,h means the methane sent to the combustion device h during the period in cubic metres.
QEn,h means the energy content of the landfill gas sent to the combustion device h during the period, in gigajoules, worked out in accordance with the monitoring requirements.
ECLFG means the energy content factor for landfill gas that is collected for combustion (methane only), in gigajoules per cubic metre, set out in Part 2 of Schedule 1 to the NGER (Measurement) Determination.

Option 3—using electricity produced by internal combustion engine
 (6) If the combustion device is an internal combustion engine, using the electricity produced by the device (QEG,h), the methane sent to the combustion device during the period is worked out using the formula (equation 10):
