be used in Divisions 3.3.6A, 3.3.6B, 3.3.6E, 3.3.7A and 3.3.7B if those Divisions are applicable to the facility.
 (4) If method 3 is used for a facility, all other available methods 3 must be used in Divisions 3.3.6A, 3.3.6B, 3.3.6E, 3.3.7A and 3.3.7B if those Divisions are applicable to the facility.

3.73K  Method 1—natural gas gathering and boosting (other than venting and flaring)
  Method 1 is:
Eij = Eijs + Eijp

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 gathering and boosting during the year measured in CO2‑e tonnes.
Eijs  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 stations (s) during the year measured in CO2‑e tonnes, given by section 3.73KA.
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 (p) during the year measured in CO2‑e tonnes, given by section 3.73KB.
3.73KA Method 1—natural gas gathering and boosting, other than emissions that are vented or flared—natural gas gathering and boosting stations
 (1) For section 3.73K, Eijs is given by the following formula:

  Eijs  = Σjs(Qis × EFj) × Sij / SDij

where:
Eijs 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 stations during the year measured in CO2‑e tonnes.
Σjs 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 natural gas gathering and boosting station (s).
Qis is the quantity of unprocessed natural gas (i) that passes through the natural gas gathering and boosting station (s) during the year, measured in tonnes in accordance with Division 2.3.6.
EFj is the emission factor for gas type (j), being methane or carbon dioxide, measured in CO2‑e tonnes per tonne of unprocessed natural gas that passes through each natural gas gathering and boosting station (s) given by subsection (2) or (3).
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 carbon dioxide SD is 0.0345.
 (2) For EFj in subsection (1), EFj for methane is given by the
