measured in kilograms of CO2‑e per gigajoule.
OFi is 0.98, which is the destruction efficiency of coal mine waste gas (i) flared.
Qk is the quantity of methane (k) within the coal mine waste gas (i) flared from the mine during the year, measured in cubic metres in accordance with Division 2.3.3.

3.16  Method 3—coal mine waste gas flared
 (1) For subparagraph 3.4(4)(a)(iii), method 3 is the same as method 2 under section 3.15.
        (2) In applying method 2 under section 3.15, the facility specific emission factor EFk must be determined in accordance with the procedure for determining EFiCO2oxec in Division 2.3.4.

Subdivision 3.2.2.4—Fugitive emissions from post‑mining activities

3.17  Method 1—post‑mining activities related to gassy mines
 (1) For subsection 3.4(6), method 1 is the same as method 1 under section 3.5.
 (2) In applying method 1 under section 3.5, EFj is taken to be 0.019, which is the emission factor for methane (j), measured in CO2‑e tonnes per tonne of run‑of‑mine coal extracted from the mine.

Division 3.2.3—Open cut mines

Subdivision 3.2.3.1—Preliminary

3.18  Application
  This Division applies to fugitive emissions from open cut mining activities.

3.19  Available methods
 (1) Subject to section 1.18, for estimating emissions released during a year from the operation of a facility that is constituted by an open cut mine the methods as set out in this section must be used.

Methane from extraction of coal
 (2) Subject to subsection (7), one of the following methods must be used for estimating fugitive emissions of methane that result from the extraction of coal from the mine:
 (a) method 1 under section 3.20;
 (b) method 2 under section 3.21;
 (c) method 3 under section 3.26.
Note: There is no method 4 for subsection (2).

Carbon dioxide from extraction of coal
 (3) If method 2 under section 3.21 is used under subsection (2), that method must be used for estimating fugitive emissions of carbon dioxide that result from the extraction of coal from the open cut mine.
 (4) If method 3 under section 3.26 is used under subsection (2), that method must be used for estimating fugitive emissions of carbon dioxide that result from the extraction of coal from the open cut mine.
Note: There is no method 1 or 4 for estimating fugitive emissions of carbon dioxide that result from the extraction of coal from an open cut mine.

Flaring
 (5) For estimating emissions released from coal mine waste gas flared from the open cut mine:
 (a) one of the following methods must be used for estimating emissions of carbon dioxide released:
 (i) method 1 under section 3.27;
 (ii) method 2 under section 3.28;
 (iii) method 3 under section 3.29; and
 (b) method 1 under section 3.27 must
