4     Onshore gas gathering and boosting pipelines (unprotected steel)  4.64 × 10‑3                         1.89 × 10‑5  tonnes CO2‑e /kilometres of pipeline hour

       3.73M  Method 3—natural gas gathering and boosting (other than venting and flaring)
(1)  Method 3 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 subsection (2).
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 3.73LB.
 (2) For subsection (1), Eijs is given by the following formula:
 Eijs = ∑k (Tik × Nik × EFijk) × 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 station during the year measured in CO2‑e tonnes.
Σk is the total emissions of gas type (j), being methane or carbon dioxide, measured in tonnes of CO2‑e and estimated by summing up the emissions released from each component type (k), if the component type is used in the natural gas gathering and boosting stations (s).
EFijk is the emission factor of gas type (j), being methane or carbon dioxide, measured in tonnes of CO2‑e per component‑hour for each component type (k) as determined under subsection (3) or (4), if the component is used in the natural gas gathering and boosting station.
Tik is:
 (a) if subsection (3) applies—the average hours of operation during the year of the component of each component type (k), if the component is used in natural gas gathering and boosting;
 (b) if subsection (4) applies—an engineering estimate of the number of hours in the year the component type (k) was operational as a leaker or non leaker based on the best available data and subsection (4).
Nik is the total number of components of each component type (k), if the component type is used in natural gas gathering and boosting.
Note: Consistent with subsection 3.41(2), emissions associated with any components included in this definition should not be counted under this section if those emissions are also counted as component emissions under another section within this Part.
Sij  is the measured share
