calculated using the following formula, measured in CO2‑e tonnes:
where:
Enlw are the emissions from non‑legacy waste.
Ej is the quantity of methane from waste deposited at the landfill, measured in CO2‑e tonnes:
Elw is the quantity of methane from legacy waste deposited at the landfill, measured in CO2‑e tonnes.

5.22M  Calculating amount of total waste deposited at landfill
  To calculate the amount of total waste deposited at a landfill, add the amount of legacy waste deposited at the landfill to the amount of non‑legacy waste deposited at the landfill.

Part 5.3—Wastewater handling (domestic and commercial)

Division 5.3.1—Preliminary

5.23  Application
 (1) This Part applies to emissions released from the decomposition of organic material, nitrification and denitrification processes, and flaring of sludge biogas, resulting from the handling of domestic or commercial wastewater through:
 (a) treatment in wastewater collection and treatment systems; or
 (b) discharge into surface waters.
 (1A) However, this Part is not applicable to a person providing a report to the Regulator under the Act whose primary activities lie outside of item 192, Water supply, sewerage and drainage services (ANZSIC code 281), in Schedule 2 of the Regulations.
 (2) In this section, domestic or commercial wastewater means liquid wastes and sludge (including human waste) from housing or commercial premises.

5.24  Available methods
 (1) Subject to section 1.18, for estimating emissions released from the operation of a facility that is constituted by wastewater handling (domestic and commercial) (the plant) during a year:
 (a) one of the following methods must be used for emissions of methane from the plant (other than from flaring of methane):
 (i) method 1 under section 5.25;
 (ii) method 2 under section 5.26;
 (iii) method 3 under section 5.30; and
 (b) one of the following methods must be used for emissions of nitrous oxide from the plant (other than from flaring of methane):
 (i) method 1 under section 5.31;
 (ii) method 2 under section 5.32;
 (iii) method 3 under section 5.36; and
 (c) one of the following methods must be used for emissions for each gas type as a result of methane flared from the plant:
 (i) method 1 under section 5.37;
 (ii) method 2 under section 5.38;
 (iii) method 3 under section 5.39.
 (2) Under paragraph (1)(c), the same method must be used for estimating emissions of each gas type.
 (3) For incidental emissions another method may be used that is consistent with the principles in section 1.13.
Note: There is no method 4 for paragraphs (1)(a), (b) and (c).

Division 5.3.2—Method 1—methane released from wastewater handling (domestic and commercial)

5.25  Method 1—methane released from wastewater handling (domestic and commercial)
 (1) For subparagraph 5.24(1)(a)(i), method 1 is:

where:
Ej is the emissions of methane released by the
