of total combustion for the year.

2.17  Simplified consumption measurements—criterion BBB
  For paragraph 2.14(d), criterion BBB is the estimation of the solid fuel combusted during a year from the operation of the facility in accordance with industry practice if the equipment used to measure combustion of the fuel is not calibrated to a measurement requirement.
Note: An estimate obtained using industry practice must be consistent with the principles in section 1.13.

Part 2.3—Emissions released from the combustion of gaseous fuels

Division 2.3.1—Preliminary

2.18  Application
  This Part applies to emissions released from the combustion of gaseous fuels in relation to a separate instance of a source if the amount of gaseous fuel combusted in relation to the separate instance of the source is more than 1000 cubic metres.

2.19  Available methods
 (1) Subject to section 1.18, for estimating emissions released from the combustion of a gaseous fuel consumed from the operation of a facility during a year:
 (a) one of the following methods must be used for estimating emissions of carbon dioxide:
 (i) method 1 under section 2.20;
 (ii) method 2 under section 2.21;
 (iii) method 3 under section 2.26;
 (iv) method 4 under Part 1.3; and
 (b) one of the following methods must be used for estimating emissions of methane:
 (i) method 1 under section 2.20;
 (ii) method 2 under section 2.27; and
 (c) method 1 under section 2.20 must be used for estimating emissions of nitrous oxide.
Note: The combustion of gaseous fuels releases emissions of carbon dioxide, methane and nitrous oxide. Method 1 is used to estimate emissions of each of these gases. There is no method 3 or 4 for emissions of methane and no method 2, 3 or 4 for emissions of nitrous oxide.
 (2) However, for incidental emissions another method may be used that is consistent with the principles in section 1.13.
 (3) Method 1 must not be used for estimating emissions of carbon dioxide for the main fuel combusted from the operation of the facility if:
 (a) the principal activity of the facility is electricity generation (ANZSIC industry classification and code 2611); and
 (b) the generating unit:
 (i) has the capacity to produce 30 megawatts or more of electricity; and
 (ii) generates more than 50 000 megawatt hours of electricity in a reporting year.

Division 2.3.2—Method 1—emissions of carbon dioxide, methane and nitrous oxide

2.20  Method 1—emissions of carbon dioxide, methane and nitrous oxide
 (1) For subparagraphs 2.19(1)(a)(i) and (b)(i) and paragraph 2.19(1)(c), method 1 for estimating emissions of carbon dioxide, methane and nitrous oxide is:

where:
Eij is the emissions of gas type (j), being carbon dioxide, methane or nitrous oxide, from each gaseous fuel type (i) released from the operation of the
