5.17B  Independent verification
 (1) After the operator of the landfill has selected a representative zone for a sub‑facility zone, the operator of the landfill must arrange for an independent expert to certify, in writing, that:
 (a) the boundaries of the representative zone are appropriate for the purpose of obtaining accurate and representative estimates of the methane being generated by the representative zone; and
 (b) the representative zone is representative of the sub‑facility zone.
 (2) The independent expert must also prepare a written report for the zone.
 (3) The report must include the details specified in the Landfill site plan and verification requirements (methods 2 and 3), published by the Clean Energy Regulator in June 2021, in relation to expert reports.
Note:         In 2021, the Landfill site plan and verification requirements (methods 2 and 3) were available at www.cleanenergyregulator.gov.au.

5.17C  Estimation of waste and degradable organic content in representative zone
  The amount of waste, and the amount of degradable organic content in the waste, disposed of in the representative zone must be estimated in accordance with sections 5.5 to 5.12 for each reporting year that waste is disposed of in the representative zone.

5.17D  Estimation of gas collected at the representative zone
 (1) The operator of the landfill must estimate the total amount, and concentration, of landfill gas measured in tonnes of methane per year collected by all of the landfill gas collection wells located within the representative zone.
 (2) Measurement of the landfill gas flow rate for each well must be undertaken in accordance with Division 2.3.6.
 (3) The methane concentration of the landfill gas from the representative zone:
 (a) may be estimated from measurements of landfill gas obtained at each gas collection well located within the representative zone using industry standard landfill gas analysers that are calibrated to the manufacturer's specifications; or
 (b) may be assumed to be the methane concentration for the landfill as analysed under Subdivision 2.3.3.2.
 (4) Data about the methane gas flow rates at each well in the representative zone must be:
 (a) the data used for operational purposes; and
 (b) recorded at least once a month for a period of at least 12 months.
 (5) Fuel flow meter equipment and gas composition monitoring equipment used to measure and analyse the landfill gas must be calibrated in accordance with:
 (a) a standard specified in section 2.24 or an equivalent standard; or
 (b) the calibration procedures specified, and at the frequencies recommended, by the manufacturer of the equipment.
 (6) Fuel flow meter equipment and gas composition monitoring equipment must be recalibrated:
 (a) at the frequency specified by the manufacturer of the equipment; or
 (b) if the
