3.70  Method 2—gas flared from crude oil refining
  For subparagraph 3.63(4)(a)(ii), method 2 is:

where:
EiCO2 is the fugitive emissions of CO2 from fuel type (i) flared in crude oil refining during the year, measured in CO2‑e tonnes.
Qh is the total quantity of hydrocarbons (h) within the fuel type (i) in crude oil refining during the year, measured in tonnes in accordance with Division 2.3.3.
EFh is the emission factor for the total hydrocarbons (h) within the fuel type (i) in the crude oil refining during the year, measured in CO2‑e tonnes per tonne of fuel type (i) flared, estimated in accordance with method 2 in Division 2.3.3.
OFi is 0.98, which is the destruction efficiency of fuel type (i) flared.
QCO2 is the quantity of CO2 within the fuel type (i) in the crude oil refining during the year, measured in CO2‑e tonnes in accordance with Division 2.3.3.

3.70A  Method 2A—crude oil refining (flared methane or nitrous oxide emissions)
  For subparagraphs 3.63(4)(b)(ii) and (c)(ii), method 2A is:
where:
EFhij is the emission factor of gas type (j), being methane or nitrous oxide, for the total hydrocarbons (h) within the fuel type (i) in crude oil refining during the year, mentioned for the fuel type in the table in subsection 3.69(2) and measured in CO2‑e tonnes per tonne of the fuel type (i) flared.
Eij is the fugitive emissions of gas type (j), being methane or nitrous oxide, from fuel type (i) flared from crude oil refining during the year, measured in CO2‑e tonnes.
OFi is 0.98, which is the destruction efficiency of fuel type (i) flared.
Qh is the total quantity of hydrocarbons (h) within the fuel type (i) in crude oil refining during the year, measured in tonnes in accordance with Division 2.3.3.

3.71  Method 3—gas flared from crude oil refining
  For subparagraph 3.63(4)(a)(iii), method 3 is the same as method 2 under section 3.70, but the emission factor EFij must be determined in accordance with method 3 for the consumption of gaseous fuels as specified in Division 2.3.4.

Division 3.3.6A—Onshore natural gas production (other than emissions that are vented or flared)

3.72  Application
  This Division applies to fugitive emissions from onshore natural gas production activities, other than emissions that are vented or flared, including emissions from onshore natural gas wellheads.

Subdivision 3.3.6A.1—Onshore natural gas production, other than emissions that are vented or flared—wellheads

3.73  Available methods
 (1) Subject to section 1.18 and subsections (3) and (4), one of the following methods must be used for estimating fugitive emissions of methane and carbon dioxide (other than emissions that are vented or flared) released during a year from the operation
