methods must be used for estimating fugitive emissions (other than emissions that are vented or flared) of each gas type, being carbon dioxide and methane, released from the operation of a facility that is constituted by natural gas storage during a year:
 (a) method 1 under section 3.78C;
 (b) method 2 under section 3.78D;
 (c) method 3 under section 3.78E.
Note: There is no method 4 for this Division.
 (2) However, for incidental emissions another method may be used that is consistent with the principles in section 1.13.
 (3) If method 2 is used for a facility, all other available methods 2 must be used in Divisions 3.3.6A, 3.3.6B, 3.3.6C, 3.3.6E 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, 3.3.6C, 3.3.6E and 3.3.7B if those Divisions are applicable to the facility.

3.78C  Method 1—natural gas storage (other than emissions that are vented or flared)
 (1) Method 1 is:

  Eij = ∑k (Qik × EFijk)

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 storage 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) specified in column 2 of an item in the table in subsection (2), if the equipment is used in the natural gas storage.
Qik is the total number of each equipment type (k) specified in column 2 of the table in subsection (2).
EFijk is the emission factor for gas type (j), being methane or carbon dioxide, measured in tonnes of gas type (j) per equipment type (k) during the year, 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 (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)
