2     Subsection 4.100(2)           Any emission (sulphur hexafluoride)

4.102  Method 1
 (1) Method 1 is:

where:
Ejk is the emissions of gas type (j), either hydrofluorocarbons or sulphur hexafluoride, summed over each equipment type (k) during a year measured in CO2‑e tonnes.
Stockjk is the stock of gas type (j), either hydrofluorocarbons or sulphur hexafluoride, contained in equipment type (k) during a year measured in CO2‑e tonnes.
Ljk is the default leakage rates for a year of gas type (j) mentioned in columns 3 or 4 of an item in the table in subsection (4) for the equipment type (k) mentioned in column 2 for that item.
 (2) For the factor Stockjk, an estimation of the stock of synthetic gases contained in an equipment type must be based on one of the following sources:
 (a) the stated capacity of the equipment according to the manufacturer's nameplate;
 (b) estimates based on:
 (i) the opening stock of gas in the equipment; and
 (ii) transfers into the facility from additions of gas from purchases of new equipment and replenishments; and
 (iii) transfers out of the facility from disposal of equipment or gas.
 (3) For equipment type (k), the equipment are the things mentioned in subregulation 4.16(1) of the Regulations.
 (4) For subsection (1), columns 3 and 4 of an item in the following table set out default leakage rates of gas type (j), for either hydrofluorocarbons or sulphur hexafluoride, in relation to particular equipment types (k) mentioned in column 2 of the item:

Item                 Equipment type (k)                                         Default annual leakage rate of gas (j)
Hydrofluorocarbons   Sulphur hexafluoride
