4 for paragraphs (a) and (b). It is proposed that a method 4 will be developed in the future.
 (4) If required, Division 5.2.7 is to be used to estimate legacy emissions.
 Note: Division 5.2.7 will not be required unless the total amount of scope 1 emissions from the operation of the facility concerned during the year is more than 100 000 tonnes CO2‑e: see paragraphs (i) of item 1 and (j) of item 2 in the column headed "Matters to be identified" in the table in Part 6 of Schedule 4.

Division 5.2.2—Method 1—emissions of methane released from landfills

5.4  Method 1—methane released from landfills (other than from flaring of methane)
 (1) For subparagraph 5.3(1)(a)(i), method 1 is:

where:
Ej is the emissions of methane released by the landfill during the year measured in CO2‑e tonnes.
CH4* is the estimated quantity of methane in landfill gas generated by the landfill during the year as determined under subsection (2) or (3) and measured in CO2‑e tonnes.
γ is the factor 6.784 × 10‑4 × GWPmethane converting cubic metres of methane at standard conditions to CO2‑e tonnes.
Qcap is the quantity of methane in landfill gas captured for combustion from the landfill during the year and measured in cubic metres in accordance with Division 2.3.6.
Qflared is the quantity of methane in landfill gas flared from the landfill during the year and measured in cubic metres in accordance with Division 2.3.6.
Qtr is the quantity of methane in landfill gas transferred out of the landfill during the year and measured in cubic metres in accordance with Division 2.3.6.
OF is the oxidation factor (0.1) for near surface methane in the landfill.
 (2) For subsection (1), if:

is less than or equal to the collection efficiency limit for the landfill calculated in accordance with section 5.15C, then:

where:
CH4gen is the quantity of methane in landfill gas generation released from the landfill during the year estimated in accordance with subsection (4) and measured in CO2‑e tonnes.
 (3) For subsection (1), if:

is greater than the collection efficiency limit for the landfill calculated in accordance with section 5.15C, then:

where:

       γ is the factor 6.784  10‑4  GWPmethane converting cubic metres of methane at standard conditions measured to CO2‑e tonnes.

       CEL is the collection efficiency limit for the landfill calculated in accordance with section 5.15C.

       CH4gen is the quantity of methane in landfill gas generation released from the landfill during the year, estimated in accordance with subsection 5.4(4) and measured in CO2‑e tonnes.

       Qcap is the quantity of methane in landfill gas captured for combustion from the landfill during the year, measured in cubic metres in accordance with Division 2.3.6.
Qflared is
