(a) as evidenced by invoices; and
 (b) as adjusted for the estimated change in the quantity of the stockpiles of carbonates or the quantity of the stockpiles of products derived from carbonates during the year.
 (2) The volume of carbonates, or products derived from carbonates, in the stockpile for the activity must be measured in accordance with industry practice.

4.37  Direct measurement at point of consumption or production—criterion AAA
 (1) For paragraph 4.35(c), criterion AAA is the direct measurement during the year of:
 (a) the quantities of carbonates consumed from the operation of the activity; or
 (b) the quantities of products derived from carbonates produced from the operation of the activity.
 (2) The measurement must be:
 (a) carried out using measuring equipment calibrated to a measurement requirement; or
 (b) for measurement of the quantities of carbonates consumed from the operation of the activity—carried out at the point of sale using measuring equipment calibrated to a measurement requirement.
 (3) Paragraph (2)(b) only applies if:
 (a) the change in the stockpile of the carbonates for the activity during the year is less than 1% of total consumption of the carbonates from the operation of the activity on average during the year; and
 (b) the stockpile of the carbonates for the activity at the beginning of the year is less than 5% of total consumption of the carbonates from the operation of the activity during the year.

4.38  Acquisition or use or disposal without commercial transaction—criterion BBB
  For paragraph 4.35(d), criterion BBB is the estimation of the consumption of carbonates, or the products derived from carbonates, during the year in accordance with industry practice if the equipment used to measure consumption of the carbonates, or the products derived from carbonates, is not calibrated to a measurement requirement.

4.39  Units of measurement
  Measurements of carbonates and products derived from carbonates must be converted to units of tonnes.

Part 4.3—Industrial processes—chemical industry

Division 4.3.1—Ammonia production

4.40  Application
  This Division applies to chemical industry ammonia production.

4.41  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 the production of ammonia:
 (a) method 1 under section 4.42;
 (b) method 2 under section 4.43;
 (c) method 3 under section 4.44;
 (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.

4.42  Method 1—ammonia production
 (1) Method 1 is:

where:
Eij is the emissions of carbon dioxide released from the production of ammonia during the year measured in CO2‑e tonnes.
Qi is the quantity of each type of feedstock or type
