SDij is the default share of gas type (j) in the unprocessed gas (i), for methane SD is 0.832 and for carbon dioxide SD is 0.0345.
 (2) For EFj in subsection (1), EFj for methane is given by the following formula:
EFj  = GWPmethane × 2.386 ×  Qi‑0.761
where:
EFj is the emission factor for methane (j) measured in CO2‑e tonnes per tonne of natural gas that passes through the natural gas gathering and boosting station during the year.
Qi is the quantity of unprocessed natural gas that passes through the natural gas gathering and boosting station during the year, measured in tonnes in accordance with Division 2.3.6.
 (3) For EFj in subsection (1), EFj for carbon dioxide is given by the following formula:
EFj  = 2.386 ×  Qi‑0.761 × SDij=carbon dioxide / SDij=methane
where:
EFj is the emission factor for carbon dioxide (j) measured in CO2‑e tonnes per tonne of natural gas that passes through the natural gas gathering and boosting station during the year.
Qi is the quantity of unprocessed natural gas that passes through the natural gas gathering and boosting station during the year, measured in tonnes in accordance with Division 2.3.6.
SDij=carbon dioxide is the default share of carbon dioxide (j) in the unprocessed gas (i), which is 0.0345.
SDij=methane is the default share of methane (j) in the unprocessed gas (i), which is 0.832.
3.73KB Method 1—natural gas gathering and boosting, other than emissions that are vented or flared—natural gas gathering and boosting pipelines
 (1) For section 3.73K, subject to subsection (3), Eijp is given by the following formula:

  Eijp  = Pk ×  EFijk × Sij / SDij

where:
Eijp is the fugitive emissions (other than emissions that are vented or flared) of gas type (j), being methane or carbon dioxide, from the natural gas gathering and boosting pipelines during the year measured in CO2‑e tonnes.
Pk is the length of the system of gathering and boosting pipelines of type (k) during the year measured in kilometres and used in the natural gas gathering and boosting.
EFijk is the emission factor for gas type (j), being methane or carbon dioxide, measured in CO2‑e tonnes per tonne of natural gas that passes through each equipment type (k), or CO2‑e tonnes per kilometre of pipeline if the equipment is used in the natural gas gathering and boosting pipelines during the year.
Sij  is the measured share of each gas type (j), being methane or carbon dioxide, in the unprocessed gas (i), by volume, measured in accordance with Division 2.3.3 and the principles in section 1.13.
SDij is the default share of gas type (j) in the unprocessed gas (i), for methane SD is 0.832 and for
