1     Liquefied natural gas station  25,700                              tonnes CO2‑e per station

3.78I  Method 2—natural gas liquefaction, storage and transfer (other than emissions that are vented or flared)
 (1) Method 2 is:

  Eij = ∑k (Tik × Nik ×EFijk)

where:
Eij is the fugitive emissions (other than venting and flaring) of methane (j) from the natural gas liquefaction, storage and transfer during the year measured in CO2‑e tonnes.
Σk is the total emissions of methane (j) measured in CO2‑e tonnes and estimated by summing up the emissions released from each equipment type (k) listed in section 6.1.2 of the API Compendium, if the equipment is used in the natural gas liquefaction, storage and transfer.
Tik is the average hours of operation during the year of each equipment type (k) listed in section 6.1.2 of the API Compendium, if the equipment is used in the natural gas liquefaction, storage and transfer.
Nik is the total number of equipment units of each equipment type (k) listed in section 6.1.2 of the API Compendium if the equipment type is used in the natural gas liquefaction, storage and transfer during the year.
EFijk is the emission factor of methane (j) measured in tonnes of CO2‑e per equipment type (k) – hour listed in section 6.1.2 of the API Compendium as determined under subsection (2), if the equipment is used in the natural gas liquefaction, storage and transfer.
 (2) For EFijk, the emission factors for methane (j) as the natural gas passes through the equipment types (k) are:
 (a) as listed in Table 6‑6 of section 6.1.2 of the API Compendium, for the equipment type; or
 (b) if the manufacturer of the equipment supplies equipment‑specific emission factors for the equipment type—those factors.

3.78J  Method 3—natural gas liquefaction, storage and transfer (other than venting and flaring)

 (1) Method 3 is:

  Eij = ∑k (Tik × Nik ×EFijk)

where:
Eij is the fugitive emissions (other than venting and flaring) of methane (j) from the natural gas liquefaction, storage and transfer during the year measured in CO2‑e tonnes.
Σk is the total emissions of methane (j) 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 liquefaction, storage and transfer.
Tik is:
 (a) if subsection (2) applies—the average hours of operation during the year of the components of each component type (k) listed in table 13 in section 4.3.1 of the API LNG Operations Consistent Methodology for Estimating Greenhouse Gas Emissions published by the American Petroleum Institute, if the component is used in the natural gas liquefaction, storage and transfer during the year; or
 (b) if subsection (3) applies—an engineering estimate of
