 (4) However, the amount of emissions to be determined for this source is only the amount of emissions from the use of coke as a carbon reductant in the metal production estimated in accordance with section 2.69.
Note: The amount of emissions to be determined for other activities is as provided for in other provisions of this Determination.

4.65  Available methods for production of a metal from an integrated metalworks
 (1) Subject to section 1.18, one of the following methods must be used for estimating emissions released from the activity during a year:
 (a) method 1 under section 4.66;
 (b) method 2 under section 4.67;
 (c) method 3 under section 4.68;
 (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.

4.66  Method 1—production of a metal from an integrated metalworks
  Method 1, based on a carbon mass balance approach, is:
Step 1                                                                                                                                                       Calculate the carbon content in fuel types (i) and carbonaceous input materials (i) delivered for the activity during the year measured in tonnes of carbon as follows:
                                                                                                                                                             where:

                                                                                                                                                             CCFi is the carbon content factor measured in tonnes of carbon for each appropriate unit of fuel type (i) mentioned in Schedule 3 or carbonaceous input material (i) consumed during the year from the operation of the activity.
                                                                                                                                                             Qi is the quantity of fuel type (i) or carbonaceous input material (i) delivered for the activity during the year measured in an appropriate unit and estimated in accordance with:
                                                                                                                                                              (a) criterion A in Divisions 2.2.5, 2.3.6, 2.4.6 and 4.2.5; or
