20. For the purposes of the quantification of the GHG emission reductions attributable to a project, the promoter must calculate the GHG emissions in the baseline scenario using Equations 2 to 8:
Equation 2
BE = CH4R-D × GWPCH4 × (1 - OX)
Where:
BE = GHG emissions in the baseline scenario, in metric tonnes CO2 equivalent;
CH4R-D = Total quantity of CH4 reclaimed or destroyed by all reclamation or destruction devices, calculated using Equation 4, in metric tonnes of CH4;
GWPCH4 = Global warming potential of CH4, taken from Schedule A.1 to the Regulation respecting mandatory reporting of certain emissions of contaminants into the atmosphere (chapter Q-2, r. 15);
OX = Factor for the oxidation of CH4 by soil bacteria, using the value established for each of the cases provided for in subparagraphs 1, 2 and 3 below.
The factor for the oxidation of CH4 by soil bacteria is established as follows:
(1)  for closed landfill sites with a geomembrane covering the entire area of the landfill in accordance with the Regulation respecting the landfilling and incineration of residual materials (chapter Q-2, r. 19), the promoter must use a CH4 oxidation rate of zero (0%);
(2)  for operating landfills, where part of the landfill is filled and covered by a geomembrane meeting the requirements of the Regulation respecting the landfilling and incineration of residual materials, the promoter must use a CH4 oxidation rate of zero (0%) for the zone covered by a geomembrane and a CH4 oxidation rate of 10% for the zone not covered by a geomembrane, and must pro-rate the CH4 oxidation factor based on the zones which are covered and uncovered by a geomembrane using Equation 3;
(3)  for all other landfill sites, the promoter must use a CH4 oxidation factor of 10%.
Equation 3
OX=(0% × ACZ) + (10% × ANCZ)
SCZ + ANCZ
Where:
OX = Factor for the oxidation of CH4 by soil bacteria for the case provided for in subparagraph 2;
ACZ = Area of the landfill site zone that is filled and covered by a geomembrane, in square metres;
ANCZ = Area of the landfill site zone that is operating and not covered by a geomembrane under final cover at the start of the reporting period, in square metres.
Equation 4
Where:
CH4R-D = Total quantity of CH4 reclaimed or destroyed by all reclamation or destruction devices, in metric tonnes of CH4;
i = Reclamation device or destruction device;
n = Number of reclamation or destruction devices;
CH4R-D,i = Quantity of CH4 reclaimed or destroyed by reclamation or destruction device i, calculated using Equation 5, in cubic metres of CH4 at standard conditions;
0.668 = Density of CH4, in kilograms per cubic metre at standard conditions;
0.001 = Conversion factor, kilograms to metric tonnes.
Equation 5
CH4R-D,i = Qi × DEi
Where:
CH4R-D,i = Quantity of CH4 reclaimed or destroyed by reclamation or destruction device i, in cubic metres of CH4 at standard conditions;
Qi = Quantity of CH4 sent to reclamation or destruction device i, calculated using Equation 6, in cubic metres of CH4 at standard conditions;
DEi = Efficiency of reclamation or destruction device i, determined in Appendix A or calculated using Equation 7 for destruction by biological oxidation;
i = Reclamation or destruction device.
Equation 6
Where:
Qi = Quantity of CH4 sent to reclamation or destruction device i, in cubic metres of CH4 at standard conditions;
t = Time interval shown in the table of monitoring parameters in Appendix D for which CH4 flow and content measurements from the landfill gas are aggregated;
n = Number of time intervals;
VLGi,t = Corrected volume of landfill gas sent to reclamation or destruction device i during time interval t, measured using a flow meter in cubic metres at standard conditions or calculated in accordance with section 21;
CCH4,t = Average concentration of CH4 in the landfill gas during time interval t, measured using a continuous CH4 analyzer, in cubic metres of CH4 per cubic metre of landfill gas.
Equation 7
DEi=(COE-CH4 – COO-CH4
COE-CH4
Where:
DEi = Efficiency of biological oxidation destruction device i, in cubic metres of CH4 per cubic metre of landfill gas;
CoE-CH4 = Average CH4 concentration of the gas entering the biological oxidation destruction device, measured using a continuous CH4 analyzer, in cubic metres of CH4 per cubic metre of landfill gas;
COO–CH4 = Average CH4 concentration of the gas at the outlet of the biological oxidation destruction device, measured using a continuous CH4 analyzer, in cubic metres of CH4 per cubic metre of landfill gas.
