 (b) if the manufacturer of the equipment supplies equipment‑specific emission factors for the equipment type—those factors are the relevant emissions factors.

3.97  Method 3—fugitive emissions from injection of greenhouse gases (other than deliberate releases from process vents, system upsets and accidents)
  Method 3 is the same as an approach mentioned in Appendix C to the API Compendium.
Note: For this method, any approach mentioned in Appendix C to the API Compendium may be used.

Division 3.4.4—Storage of greenhouse gases

Subdivision 3.4.4.1—Preliminary

3.98  Application
  This Division applies to fugitive emissions to the atmosphere of greenhouse gases from geological formations used for storage of a greenhouse gas captured for permanent storage.
Note: A greenhouse gas is captured for permanent storage in a geological formation if the gas is captured by, or transferred to, the holder of a licence, lease or approval mentioned in section 1.19A, under a law mentioned in that section, for the purpose of being injected into a geological formation (however described) under the licence, lease or approval.

3.99  Available method
  For estimating fugitive emissions of greenhouse gases released during a year from a geological formation used for the permanent storage of a greenhouse gas, method 2 set out in section 3.100 must be used.
Note: There is no method 1, 3 or 4 for this Division.

Subdivision 3.4.4.2—Fugitive emissions from the storage of greenhouse gases

3.100  Method 2—fugitive emissions from geological formations used for the storage of greenhouse gases
 (1) Method 2 is:
where:
Ccst is the closing stock of a stored greenhouse gas at the storage site for the reporting year, measured in CO2‑e tonnes.
Cost is the opening stock of a stored greenhouse gas at the storage site for the reporting year, determined in accordance with subsection (2), measured in CO2‑e tonnes.
ECO2 is the fugitive emissions to the atmosphere of greenhouse gas during the reporting year from the geological storage formation, determined in accordance with subsection (3), measured in CO2‑e tonnes.
Qinj is the quantity of a greenhouse gas injected into the geological formation during the reporting year, measured in CO2‑e tonnes.
Note: This formula represents Ccst (the closing stock) as the cumulative mass of a greenhouse gas injected into the geological formation in all years since the commencement of injection, less any fugitive emissions to the atmosphere.
 The closing stock of a greenhouse gas in the storage site for the reporting year is derived from the opening stock determined in accordance with subsection (2), the quantity injected into the geological formation during the reporting year, and estimates of fugitive emissions to the atmosphere determined in accordance with subsection (3).
