contained in gas bearing strata for an open cut coal mine must be estimated in accordance with the emissions estimation process mentioned in section 1 of the ACARP Guidelines.
 (2) The gas distribution model used for estimating emissions must be applied in accordance with section 4.1 of the ACARP Guidelines; and
 (3) The modelling bias must be assessed in accordance with section 4.2 of the ACARP Guidelines.
 (4) The gas distribution model must be applied to the geology model in accordance with section 4.3 of the ACARP Guidelines.

3.26  Method 3—extraction of coal
 (1) For paragraph 3.19(2)(c) and subsection 3.19(4), method 3 is the same as method 2 under section 3.21
 (2) In applying method 2 under section 3.21 a sample of gas bearing strata must be collected in accordance with an appropriate standard, including:
 (a) AS 2617—1996 Sampling from coal seams or an equivalent standard; and
 (b) AS 2519—1993 Guide to the technical evaluation of higher rank coal deposits or an equivalent standard.

Subdivision 3.2.3.3—Emissions released from coal mine waste gas flared

3.27  Method 1—coal mine waste gas flared
 (1) For subparagraph 3.19(5)(a)(i) and paragraph 3.19(5)(b) and paragraph (5)(c), method 1 is the same as method 1 under section 3.14.
 (2) In applying method 1 under section 3.14, a reference to an underground mine is taken to be a reference to an open cut mine.

3.28  Method 2—coal mine waste gas flared
  For subparagraph 3.19(5)(a)(ii), method 2 is the same as method 2 under section 3.15.

3.29  Method 3—coal mine waste gas flared
  For subparagraph 3.19(5)(a)(iii), method 3 is the same as method 3 under section 3.16.

Division 3.2.4—Decommissioned underground mines

Subdivision 3.2.4.1—Preliminary

3.30  Application
  This Division applies to fugitive emissions from decommissioned underground mines from the time that they became a decommissioned underground coal mine, other than mines which have been a decommissioned underground coal mine for a continuous period of 20 years or more.

3.31  Available methods
 (1) Subject to sections 1.18 and 3.30, for estimating emissions released during a year from the operation of a facility that is constituted by a decommissioned underground mine the methods as set out in this section must be used.

Methane from decommissioned mines
 (2) One of the following methods must be used for estimating fugitive emissions of methane that result from the mine:
 (a) subject to subsection (6), method 1 under section 3.32;
 (b) method 4 under section 3.37.
Note: There is no method 2 or 3 for subsection (2).

Carbon dioxide from decommissioned mines
 (3) If method 4 under section 3.37 is used under subsection (2), that method must be used for estimating fugitive emissions of carbon dioxide that result from the mine.
Note: There is no method 1,
