method 3 for the combustion of gaseous fuels is the same as method 2, but the carbon dioxide emissions factor EFh must be determined in accordance with method 3 in Division 2.3.4.

Combustion of liquid fuels (flared) emissions
 (2) For subparagraph 3.43(1)(a)(iii), method 3 for the combustion of liquid fuels is the same as method 2, but the carbon dioxide emissions factor EFh must be determined in accordance with method 3 in Division 2.4.4.

Subdivision 3.3.2.3—Oil or gas exploration and development—fugitive emissions from system upsets, accidents and deliberate releases

3.46A  Available methods
 (1) Subject to section 1.18, the methods mentioned in subsections (2) and (3) must be used for estimating fugitive emissions that result from system upsets, accidents and deliberate releases during a reporting year from the operation of a facility that is constituted by oil or gas exploration and development.
 (2) To estimate emissions for methane and carbon dioxide that result from deliberate releases from system upsets, accidents and deliberate releases from process vents at a facility during a year, for each oil or gas exploration and development activity one of the following methods must be used:
 (a) method 1 under:
 (i) section 3.46AB (natural gas well completions); and
 (ii) section 3.56B (emissions from system upsets, accidents and deliberate releases from process vents); and
 (iii) section 3.85B (cold process vents); and
 (iv) section 3.85P (well workovers); and
 (v) section 3.46AC (mud degassing).
 (b) method 4 under:
 (i)  for emissions of methane and carbon dioxide from natural gas well completions activities, well workovers, cold process vents and well blowouts—section 3.46B; and
 (ii) for emissions and activities not mentioned in subparagraph (i)—Part 1.3.
 (3) For estimating incidental emissions that result from deliberate releases from system upsets, accidents and deliberate releases from process vents during a year from the operation of the facility, another method may be used that is consistent with the principles mentioned in section 1.13.
Note: There is no method 2 or 3 for this Subdivision.

Subdivision 3.3.2.3.1—Fugitive emissions that result from deliberate releases from process vents, system upsets and accidents–well completions

3.46AB  Method 1—vented emissions from natural gas well completions
 (1)  Method 1 is:

  Eij  = Σk   Qik   ×  EFijk  × Sij / SDij

where:
Eij is the fugitive emissions of gas type (j), being methane or carbon dioxide, vented from the natural gas exploration and development during the year measured in CO2‑e tonnes.
Σk is the total emissions of gas type (j), being methane or carbon dioxide, measured in tonnes of CO2‑e and estimated by summing up the emissions released from all of the equipment of type (k) specified in column 2 of the table in subsection (2), if the equipment is used in the natural gas
