1     Natural gas storage station  10,336                              20.7  tonnes CO2‑e per station

3.78D  Method 2—natural gas storage (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 emissions that are vented or flared) of methane or carbon dioxide (j) from the natural gas storage during the year measured in CO2‑e tonnes.
Σk is the total emissions of methane or carbon dioxide (j) 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 storage.
Tik is the average hours of operation during the year of each equipment type (k), if the equipment is used in the natural gas storage during the year.
Nik is the total number of each equipment type (k), if the equipment type is used in the natural gas storage during the year.
EFijk is the emission factor of methane or carbon dioxide (j) 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 storage.
 (2) For EFijk in subsection (1), column 3 of an item in the following table specifies the emission factor for methane or carbon dioxide (j) for an equipment type (k) specified in column 2 of that item and column 4 of an item in the following table specifies the emission factor for carbon dioxide (j) for an equipment type (k) specified in column 2 of that item:
Item  Equipment type (k)           Emission factor for gas type  (j)
