landfill gas flared from the sub‑facility zone during the reporting year, measured in cubic metres in accordance with Division 2.3.6.
Lrz is the ratio of methane generated by legacy waste deposited in a sub‑facility zone to methane generated by all waste deposited in a sub‑facility zone.

5.22E  How to estimate quantity of methane captured for transfer out of landfill from legacy waste for each sub‑facility zone
  The quantity of methane captured for transfer out of the landfill from legacy waste for each sub‑facility zone must be estimated using the following formula:
where:
Qtrlw z is the estimated quantity of methane captured for transfer out of the landfill from legacy waste for each sub‑facility zone.
Qtr z is the total quantity of methane in landfill gas transferred out of the sub‑facility zone during the reporting year, measured in cubic metres in accordance with Division 2.3.6.
Lrz is the ratio of methane generated by legacy waste deposited in a sub‑facility zone to methane generated by all waste deposited in a sub‑facility zone.

5.22F  How to calculate the quantity of methane generated from legacy waste for a sub‑facility zone (CH4genlw z)
  Calculate CH4genlw z:
 (a) using the estimates, equations and methods set out in sections 5.4 to 5.22K; and
 (b) when using those estimates, equations and methods—by replacing:
 (i) waste deposited in a landfill with legacy waste deposited in a sub‑facility zone; and
 (ii) the quantity of methane in landfill gas captured for combustion from the landfill with the quantity of methane in landfill gas captured for combustion from legacy waste in the sub‑facility zone; and
 (iii) the quantity of methane in landfill gas flared from the landfill with the quantity of methane in landfill gas flared from legacy waste in the sub‑facility zone; and
 (iv) the quantity of methane in landfill gas captured for transfer out of the landfill with the quantity of methane in landfill gas captured for transfer out of the landfill from legacy waste in the sub‑facility zone.

5.22G  How to calculate total methane generated from legacy waste
  Total methane generated from legacy waste is equal to the sum of methane generated from legacy waste for all sub‑facility zones and is calculated using the following formula:
where:
CH4genlw is the methane generated from legacy waste deposited at the landfill, measured in CO2‑e tonnes.
∑z is the sum of all sub‑facility zones.
CH4genlw z is the quantity of methane generated from legacy waste in a sub‑facility zone, measured in CO2‑e tonnes, calculated in accordance with section 5.22F.

5.22H  How to calculate total methane captured and combusted from methane generated from legacy waste
  Total methane captured and combusted from methane generated from legacy waste is equal to the sum of methane
