Division 4.4.2—Ferroalloys production

4.69  Application
 (1) This Division applies to emissions of carbon dioxide from any of the following:
 (a) the consumption of a fossil fuel reductant during the production of:
 (i) a ferroalloy; or
 (ii) silicomanganese; or
 (iii) silicon;
 (b) the oxidation of a fossil fuel electrode in the production of:
 (i) a ferroalloy; or
 (ii) silicomanganese; or
 (iii) silicon.
 (2) In this section:
ferroalloy means an alloy of 1 or more elements with iron including, but not limited to, any of the following:
 (a) ferrochrome;
 (b) ferromanganese;
 (c) ferromolybdenum;
 (d) ferronickel;
 (e) ferrosilicon;
 (f) ferrotitanium;
 (g) ferrotungsten;
 (h) ferrovanadium.

4.70  Available methods
 (1) Subject to section 1.18, one of the following methods must be used for estimating emissions of carbon dioxide during a year from the operation of a facility that is constituted by the production of ferroalloy metal, silicomanganese or silicon:
 (a) method 1 under section 4.71;
 (b) method 2 under section 4.72;
 (c) method 3 under section 4.73;
 (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.

4.71  Method 1—ferroalloy metal
  Method 1, based on a carbon mass balance approach, is:
Step 1                                                                                                                                                        Work out the carbon content in fuel types (i) or carbonaceous input material delivered for the activity during the year, measured in tonnes of carbon, as follows:

                                                                                                                                                              where:
                                                                                                                                                              i means the sum of the carbon content values obtained for all fuel types (i) or carbonaceous input material.
                                                                                                                                                              CCFi is the carbon content factor mentioned in Schedule 3, measured in tonnes of carbon, for each appropriate unit of fuel type (i) or carbonaceous input material consumed during the year from the operation of the activity.
                                                                                                                                                              Qi is the quantity of fuel type (i) or carbonaceous input material 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
