Asha must be determined by sampling and analysing the fuel type for sulphur and ash content, as the case may be, in accordance with:
 (a) for solid fuels—method 2 in Division 2.2.3; and
 (b) for gaseous fuels—method 2 in Division 2.3.3; and
 (c) for liquid fuels—method 2 in Division 2.4.3.
 (3) However, in applying method 1 under section 4.76, the factor Sa may be the amount for the factor as mentioned in section 4.76.
 (4) If the amount for the factor Sa as mentioned in section 4.76 is not used, then Sa must be determined by sampling and analysing the fuel type (i) for sulphur content in accordance with subsection (2).

4.78  Method 3—aluminium (carbon anode consumption)
 (1) Subject to this section, method 3 is the same as method 1 under section 4.76.
 (2) In applying method 1 under section 4.76, the method for sampling and analysing fuel type (i) for the factors NAC, Sa and Asha must be determined by sampling and analysing the fuel type for sulphur and ash content, as the case may be, in accordance with:
 (a) for solid fuels—method 3 in Division 2.2.4; and
 (b) for gaseous fuels—method 3 in Division 2.3.4; and
 (c) for liquid fuels—method 3 in Division 2.4.4.

Subdivision 4.4.3.2—Aluminium—emissions from production of baked carbon anodes in aluminium production

4.79  Available methods
 (1) Subject to section 1.18, for estimating emissions of carbon dioxide released during a year from the operation of a facility that is constituted by the production of aluminium involving the production of baked carbon anodes, one of the following methods must be used:
 (a) method 1 under section 4.80;
 (b) method 2 under section 4.81;
 (c) method 3 under section 4.82;
 (d) method 4 under Part 1.3.
 (2) However, for incidental emissions another method may be used that is consistent with the principles in section 1.13.

4.80  Method 1—aluminium (baked carbon anode production)
  Method 1 is:

where:
Eij is the emissions of carbon dioxide released from baked carbon anode production for the facility during the year.
GA is the initial weight of green anodes used in the production process of the baked carbon anode.
Hw is the weight of the hydrogen content in green anodes used in the production of the baked carbon anode during the year measured in tonnes.
BA is the amount of baked carbon anode produced during the year measured in tonnes.
WT is the amount, in tonnes, of waste tar collected in the production of baked carbon anodes during the year.
ΣQi is the quantity of fuel type (i), measured in the appropriate unit, consumed in the production of baked carbon anodes during the year and estimated in accordance with the requirements set out in
