positions for the PEM equipment;
 (b) the requirements in section 3.10 about measurement of volumetric flow rates in a gas stream;
 (c) the requirements in section 3.11 about measurement of the concentrations of gas type (j) in the gas stream;
 (d) the requirements in section 3.12 about representative data.
 (e) the requirements in section 3.13 about performance characteristics of equipment.

3.9  Selection of sampling positions for PEM
  For paragraph 3.8(a), an appropriate standard or applicable State or Territory legislation must be complied with for the location of sampling positions for PEM equipment.
Note: Appropriate standards include:
 AS 4323.1—1995/Amdt 1‑1995, Stationary source emissions—Selection of sampling positions
 USEPA Method 1—Sample and velocity traverses for stationary sources (2000)

3.10  Measurement of volumetric flow rates by PEM
  For paragraph 3.8(b), the measurement of the volumetric flow rates by PEM of the gas stream must be undertaken in accordance with an appropriate standard or applicable State or Territory legislation.
Note: Appropriate standards include:
 ISO 14164:1999 Stationary source emissions. Determination of the volume flowrate of gas streams in ducts – automated method
 ISO 10780:1994 Stationary source emissions. Measurement of velocity and volume flowrate of gas streams in ducts
 USEPA Method 2—Determination of stack gas velocity and volumetric flow rate (Type S Pitot tube) (2000)
 USEPA Method 2A—Direct measurement of gas volume through pipes and small ducts (2000).

3.11  Measurement of concentrations by PEM
  For paragraph 3.8(c), the measurement of the concentrations of gas type (j) in the gas stream by PEM must be undertaken in accordance with an appropriate standard or applicable State or Territory legislation.
Note: Appropriate standards include USEPA—Method 3C—Determination of carbon dioxide, methane, nitrogen and oxygen from stationary sources (1996).

3.12  Representative data for PEM
 (1) For paragraph 3.8(d), sampling by PEM must be undertaken during the year for a sufficient duration to produce representative data that may be reliably extrapolated to provide estimates of emissions across the full range of operating conditions for that year.
 (2) Emission estimates of PEM equipment must also be consistent with the principles in section 1.13.

3.13  Performance characteristics of equipment
  For paragraph 3.8(e), the performance characteristics of PEM equipment must be consistent with an appropriate standard or applicable State or Territory legislation.
Note: The performance characteristics of PEM equipment includes calibration.

Subdivision 3.2.2.3—Emissions released from coal mine waste gas flared

3.14  Method 1—coal mine waste gas flared
  For subparagraph 3.4(4)(a)(i) and paragraphs 3.4(4)(b) and (c), method 1 is:

where:
E(fl)ij is the emissions of gas type (j) released from coal mine waste gas (i) flared from the mine during the year, measured in CO2‑e tonnes.
Qi,flared is the quantity of coal mine waste gas (i) flared from the mine during
