if:
 (a) the waste has been deposited in a sub‑facility zone; and
 (b) a methane generation constant for the solid waste has been:
 (i) estimated under method 2; and
 (ii) used in the previous reporting year.
 (6) For each waste mix type mentioned in column 3 of the table in subsection 5.14(6), ki must be applied in the calculation of methane:
 (a) generated from solid waste deposited in a representative zone in a reporting year; and
 (b) generated from solid waste deposited in every sub‑facility zone in each reporting year for which an independent expert has certified, in accordance with section 5.17B, that the representative zone is representative of the sub‑facility zone; and
 (c) if the methane is calculated using the estimates mentioned in paragraph 5.14A(a), (b), (c) or (d) and all of the following:
 (i) the fraction of organic carbon dissimilated mentioned in column 3 of the table in section 5.14A;
 (ii) the methane correction factor for aerobic decomposition mentioned in section 5.14B;
 (iii) the fraction by volume of methane generated in landfill gas mentioned in section 5.14C.
Note 1: For provisions regarding the selection and requirements of representative zones, see sections 5.16 to 5.17I.
Note 2: Section 5.17AA sets out, for a landfill operator using method 2 in Division 5.2.3 or method 3 in Division 5.2.4, the number of sub‑facility zones that the landfill operator may select and the requirements for sub‑facility zones that the landfill operator must comply with.
Note 3: Section 5.22A sets out, for a landfill operator using method 1 in Division 5.2.2 to estimate emissions of methane released from legacy waste in a landfill, options and requirements related to sub‑facility zones.

Division 5.2.4—Method 3—emissions of methane released from solid waste at landfills

5.18  Method 3—methane released from solid waste at landfills (other than from flaring of methane)
 (1) For subparagraph 5.3(1)(a)(iii) and subject to subsection (2), method 3 is the same as method 2 under section 5.15.
 (2) In applying method 2 under section 5.15, the gas flow rate must be estimated from sampling undertaken during the year in accordance with USEPA Method 2E—Determination of landfill gas production flow rate, as set out in Appendix A‑1 of Title 40, Part 60 of the Code of Federal Regulations, United States of America, or an equivalent Australian or international standard.

Division 5.2.5—Solid waste at landfills—Flaring

5.19  Method 1—landfill gas flared
 (1) For subparagraph 5.3(b)(i), method 1 is:

where:
Ej flared is the emissions of gas type (j), being methane and nitrous oxide, released from the landfill from flaring of the methane in landfill gas during the year measured in CO2‑e tonnes.
Qflared is the quantity of methane in landfill gas flared during the year measured in
