3.15 Measuring the quantity of biogas sent to combustion device h (Qbiogas,h)
Qbiogas, h must be measured in accordance with the following requirements:
(1) Gas flow must be measured:
(a) at the delivery location of the gaseous fuel;
(b) using a gas volumetric flow meter that uses a continuous monitoring system; and
(c) in cubic metres per hour (m3 per hour).
(2) Subject to subsection (1), gas flow must be measured using equipment that:
(a) is rated for use with a process gas/biogas/dirty stream;
(b) is rated for use at the expected flow rate and pressure;
(c) is designed for use in the anticipated operating temperature range; and
(d) the meter is to be accurate to +/‑ 5% for flow measurement.
(3) Gas flow must be continuously recorded and integrated using an integration device that is isolated from the flow computer in such a way that if the computer fails, the integration device will retain the last reading, or the previously stored information, that was on the computer immediately before the failure.
(4) All measurements must comply with the National Measurement Act.
3.16 Measuring the proportion of volume of biogas that is methane (Image unavailable in extracted text)
(1) The percentage of methane in biogas (Image unavailable in extracted text),is either:
(a) the default value prescribed in the NGER (Measurement) Determination; or
(b) the composition of biogas at the project site measured using an inline gas analyser; or
(c) the composition of biogas resulting from the analysis of biogas samples in a NATA accredited laboratory.
(2) Where subsection (1) (b) applies, the following requirements apply:
(a) paired values of the methane fraction of the gas and gas flow that are averaged for the same time interval must be used in the calculation of emission reductions; and
(b) measurement of the methane fraction must occur at the same time as flow measurement.
(3) Where subsection (1) (c) applies, the following requirements apply:
(a) gas composition samples must be taken at the delivery location of the gaseous fuel;
(b) gas composition samples must be taken on a regular basis, occurring no less than once per month;
(c) the sampling vessel must be set up to provide a time period for the instrument to stabilise and carry out initial checks in accordance with the instrument provided by the manufacturer; and
(d) there must be no leaks in the sampling train or between the sampling train and the instrument; and
(e) gas samples must be analysed using US EPA Method 3 gas chromatography or mass spectrometry.

Division 4.1 Project monitoring
4.1 Application
For the purposes of subsection 106 (3) of the Act, a project proponent of an eligible offsets project must comply with the monitoring, record-keeping and reporting requirements of this Part.
4.2 Quality assurance and quality control
(1) All monitoring instruments must be:
(a) cleaned and inspected on a regular basis to ensure the equipment operates within an accuracy threshold of +/- 5%, with the activities performed and the “as found/as left” condition of the equipment documented;
(b) field checked for calibration accuracy, with the per cent drift documented, within two months before the end of the reporting period by a third-party technician:
(i) using an appropriate instrument or apparatus; or
(ii) as per the manufacturer’s guidance; and
(c) calibrated by the manufacturer or an accredited third-party calibration service with the frequency recommended by the manufacturer’s guidance, or every 5 years, whichever occurs with greater frequency.
(2) Field checks of monitoring instruments must determine whether the instrument reads measurement within the accuracy threshold of +/-5%.
(3) If a field check of a monitoring instrument determines that its accuracy is outside of the accuracy threshold of +/-5% then the instrument must be calibrated by the manufacturer or an accredited third-party calibration service. The calibration must ensure that the instrument reads measurement within the accuracy threshold of +/-5%.
(4) All combustion devices must be installed, operated and maintained in accordance with the manufacturer’s guidance.
