a  The emission factor at Table 5‑26 'Gas storage station venting' must be used for each instance of a natural gas storage station if emissions are estimated according to section 5.7.4.

Subdivision 3.3.9E.2—Natural gas storage (emissions that are flared)
3.88N Available methods
 (1) For estimating emissions released from gas flared from natural gas storage:
 (a) one of the following methods must be used for estimating emissions of carbon dioxide released:
 (i) method 1 under section 3.86;
 (ii) method 2 under section 3.87;
 (iii) method 3 under section 3.88; and
 (b) if estimating emissions of methane released—one of the following methods must be used:
 (i) method 1 under section 3.86;
 (ii) method 2A under section 3.87A; and
 (c) if estimating emissions of nitrous oxide released—one of the following methods must be used:
 (i) method 1 under section 3.86;
 (ii) method 2A under section 3.87A.
Note: The flaring of gas from natural gas storage releases emissions of carbon dioxide, methane and nitrous oxide. The reference to gas type (j) in method 1 in section 3.86 is a reference to these gases. The same formula is used to estimate emissions of each of these gases. There is no method 4 for emissions of carbon dioxide and no method 2, 3 or 4 for emissions of nitrous oxide or methane.
 (2) However, for incidental emissions another method may be used that is consistent with the principles in section 1.13.

Division 3.3.9F— Natural gas liquefaction, storage and transfer (emissions that are vented or flared)

3.88O  Application
  This Division applies to fugitive emissions from venting or flaring from natural gas liquefaction, storage and transfer activities, including emissions from:
 (a)  the venting of natural gas; and
 (b) the venting of waste gas and vapour streams at facilities that are constituted by natural gas liquefaction, storage and transfer activities; and
 (c) the flaring of natural gas, waste gas and waste vapour streams at those facilities.

Subdivision 3.3.9F.1—Natural gas liquefaction, storage and transfer (emissions that are vented)

3.88P  Available methods
 (1) Subject to section 1.18, method 1 under section 3.88Q must be used for estimating fugitive emissions from gas vented from natural gas liquefaction, storage and transfer (emissions that are vented) activities.
Note: There is no method 2, 3 or 4 for this Division.
 (2) However, for incidental emissions another method may be used that is consistent with the principles in section 1.13.

3.88Q  Method 1—emissions from system upsets, accidents and deliberate releases from process vents— natural gas liquefaction, storage and transfer
  Method 1 is, for a process mentioned in column 2 of an item in the following table, as described in the section of the API Compendium mentioned in column 3 for
