3.82  Method 2—natural gas distribution
 (1) Method 2 is:

where:
Ej is the fugitive emissions of gas type (j) that result from the natural gas distribution during the year measured in CO2‑e tonnes.
Σk is the total of emissions of gas type (j) measured in CO2‑e tonnes and estimated by summing up the emissions from each equipment type (k) listed in sections 5 and 6.1.2 of the API Compendium, if the equipment is used in the natural gas distribution.
Qk is the total of the quantities of natural gas measured in tonnes that pass through each equipment type (k) or the number of equipment units of type (k) listed in sections 5 and 6.1.2 of the API Compendium, if the equipment is used in the natural gas distribution.
EFjk is the emission factor for gas type (j) measured in CO2‑e tonnes for each equipment type (k) listed in sections 5 and 6.1.2 of the API Compendium as determined under subsection (2), if the equipment is used in the natural gas distribution.
 (2) For EFjk, the emission factors for gas type (j) as the natural gas passes through the equipment type (k) are:
 (a) as listed in sections 5 and 6.1.2 of the API Compendium; or
 (b) as listed in that Compendium for the equipment type with emission factors adjusted for variations in estimated gas composition, in accordance with that Compendium's Sections 5 and 6.1.2, and the requirements of Division 2.3.3; or
 (c) as listed in that Compendium for the equipment type with emission factors adjusted for variations in the type of equipment material using adjusted factors; or
 (d) if the manufacturer of the equipment supplies equipment‑specific emission factors for the equipment type—those factors.
 (3) In paragraph 3.82(2)(c), a reference to factors adjusted is a reference to the factors in Table 5‑3 of the publication entitled Greenhouse Gas Emission Estimation Methodologies, Procedures and Guidelines for the Natural Gas Distribution Sector, American Gas Association, April 2008, that are adjusted for variations in estimated gas composition in accordance with:
 (a) section 5.2.1 of that publication; and
 (b) Division 2.3.3.

3.82A  Method 3—natural gas distribution
 (1) Method 3 is:
Ejp = Sp × %UAGp × 0.373 × Cjp
where:
Ejp is the fugitive emissions (other than emissions that are flared) of gas type (j) that result from natural gas distribution through a system of pipelines with sales of gas in a State or Territory (p) during the year, measured in CO2‑e tonnes.
Sp is the total sales during the year from the pipeline system in a State or Territory (p), measured in terajoules.
%UAGp is the percentage of unaccounted for gas in the pipeline system in a State or
