natural gas that passes through the natural gas processing station (s) during the year.
Qi is the quantity of unprocessed natural gas that passes through the natural gas processing station during the year, measured in tonnes in accordance with Division 2.3.6.
 (3) For EFijs in subsection (1), EFijs for carbon dioxide is given by the following formula:
EFijs  = 0.6369 ×  Qi‑0.4801 × SDij=carbon dioxide / SDij=methane
where:
EFijs is the emission factor for carbon dioxide (j) measured in CO2‑e tonnes per tonne of natural gas that passes through the natural gas processing station (s) during the year.
Qi is the quantity of unprocessed natural gas that passes through the natural gas processing 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.

3.73R  Method 2—natural gas processing (other than venting and flaring)
 (1) Method 2 is:

  Eij = [∑k (Tik × Nik ×EFijk) × Sij/SDij]

where:
Eij 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 processing during the year measured in CO2‑e tonnes.
Σk is the total emissions of gas type (j), being methane or carbon dioxide, measured in CO2‑e tonnes and estimated by summing up the emissions released from each equipment type (k), if the equipment is used in the natural gas processing.
Tik is the average hours of operation during the year of the equipment of each equipment type (k), if the equipment is used in the natural gas processing during the year.
Nik is the total number of equipment units of each equipment type (k), if the equipment type is used in the natural gas processing during the year.
EFijk is the emission factor (A) of gas type (j), being methane or carbon dioxide, measured in tonnes of CO2‑e per equipment type (k) – hour as determined under subsection (2), if the equipment is used in the natural gas processing.
Sij  is the measured share of 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 0.868 and for carbon dioxide SD is 0.0345.
 (2) For EFijk in subsection (1), column 3 of an item in the following table specifies the emission factor for methane (j) for an equipment type (k) specified in column 2 of that item
