production of a commodity, by an industry, mentioned in column 1 of an item of the table in subsection 5.42(8).

5.41  Available methods
 (1) Subject to section 1.18 one of the following methods must be used for estimating emissions of methane released from the operation of a facility (other than by flaring of landfill gas containing methane) that is constituted by wastewater handling generated by the relevant industries (the plant) during a year:
 (a) method 1 under section 5.42;
 (b) method 2 under section 5.43;
 (c) method 3 under section 5.47.
 (2) Subject to section 1.18, one of the following methods must also be used for estimating emissions of each gas type released as a result of methane in sludge biogas flared from the operation of the plant during a year:
 (a) method 1 under section 5.48;
 (b) method 2 under section 5.49;
 (c) method 3 under section 5.50.
 (3) Under subsection (2), the same method must be used for estimating emissions of each gas type.
 (4) 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 subsection (1) or (2).

Division 5.4.2—Method 1—methane released from wastewater handling (industrial)

5.42  Method 1—methane released from wastewater handling (industrial)
 (1) For paragraph 5.41(1)(a), method 1 is:

where:
Ej is the emissions of methane released from the plant during the year measured in CO2‑e tonnes.
CH4* is the estimated quantity of methane in sludge biogas generated by the plant during the year measured in CO2‑e tonnes as determined under subsections (2) and (3).
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 sludge biogas captured for combustion for the plant during the year measured in cubic metres in accordance with Division 2.3.6.
Qflared is the quantity of methane in sludge biogas flared by the plant during the year measured in cubic metres in accordance with Division 2.3.6.
Qtr is the quantity of methane in sludge biogas transferred out of the plant during the year measured in cubic metres in accordance with Division 2.3.6.
 (2) For subsection (1), if:

is less than or equal to 0.75, then:

where:
CH4gen is the quantity of methane in sludge biogas produced by the plant during the year, estimated in accordance with subsection (5) and measured in CO2‑e tonnes.
 (3) For subsection (1), if:

is greater than 0.75, then:

where:
γ is the factor 6.784 x 10‑4 x GWPmethane converting cubic metres of methane at standard conditions to CO2‑e tonnes.
Qcap is the quantity of methane in sludge biogas captured for combustion for the operation of the
