Division 4.2.4—Soda ash use and production

4.26  Application
  This Division applies to emissions from the use of soda ash and emissions of carbon dioxide from the chemical transformation of calcium carbonate, sodium chloride, ammonia and coke into sodium bicarbonate and soda ash.
Examples of uses of soda ash in industrial processes:
         1 Glass production.
         2 Soap and detergent production.
         3 Flue gas desulphurisation.
         4 Pulp and paper production.

4.27  Outline of Division
  Emissions released from the use and production of soda ash must be estimated in accordance with:
 (a) for the use of soda ash in production processes—Subdivision 4.2.4.1; or
 (b) for the production of soda ash—Subdivision 4.2.4.2.

Subdivision 4.2.4.1—Soda ash use

4.28  Available methods
 (1) Subject to section 1.18, one of the following methods must be used for estimating emissions of carbon dioxide released during a year from the operation of a facility constituted by the use of soda ash in a production process:
 (a) method 1 under section 4.29;
 (b) method 4 under Part 1.3.
         Note: There is no method 2 or 3 for this Division.
 (2) However, for incidental emissions another method may be used that is consistent with the principles in section 1.13.

4.29  Method 1—use of soda ash
  Method 1 is:

where:
Eij is the emissions of carbon dioxide (j) from soda ash (i) consumed in the production process during the year measured in CO2‑e tonnes.
Qi is the quantity of soda ash (i) consumed in the production process during the year measured in tonnes and estimated under Division 4.2.5.
EFij is 0.415, which is the carbon dioxide (j) emission factor for soda ash (i) measured in tonnes of carbon dioxide emissions per tonne of soda ash.

Subdivision 4.2.4.2—Soda ash production

4.30  Available methods
 (1) Subject to section 1.18, one of the following methods must be used for estimating emissions released during a year from the operation of a facility that is constituted by an activity that produces soda ash:
 (a) method 1 under section 4.31;
 (b) method 2 under section 4.32;
 (c) method 3 under section 4.33;
 (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.

4.31  Method 1—production of soda ash
  Method 1 is:
Step 1                                                                                                                                                         Calculate the carbon content in fuel type (i) or carbonate material (j) delivered for the activity during the year measured in tonnes of carbon as follows:
                                                                                                                                                               where:
                                                                                                                                                               ∑i means sum the carbon content values obtained for all fuel types (i).
                                                                                                                                                               CCFi is the carbon content factor mentioned in Schedule 3 measured in tonnes of carbon for each appropriate unit of fuel type (i) consumed during the year from the
