Q-2, r. 35.3.01 - Regulation respecting manure anaerobic digestion projects eligible for the issuance of offset credits

Full text
21. To quantify the avoided CH4 emissions attributable to the project, the promoter must calculate the CH4 emissions in the baseline scenario using Equations 3 to 8:
Equation 3: Calculation of total CH4 emissions from manure pits at all agricultural facilities
Where:
DE = Total CH4 emissions from the decomposition of manure in manure pits, in metric tonnes CH4;
n = Number of agricultural facilities;
i = Agricultural facility;
QCH4max,i = Maximum CH4 production from manure for the eligible project at facility i, in cubic metres at standard conditions, calculated using Equation 4;
ρCH4 = Density of CH4, in kilograms per cubic metre = 0.668;
MCFpit = conversion factor for CH4 in manure pits, as determined in Table 1 of Appendix D;
0.001 = Conversion factor, kilograms to metric tonnes.
Equation 4: Calculation of maximum methane production from eligible manure, by agricultural facility
Where:
QCH4max,i = Maximum CH4 production from eligible manure at facility i, in cubic metres at standard conditions;
k = Number of livestock categories;
j = Livestock category from Table 1 in Appendix C;
QLi = Quantity of manure from agricultural facility i processed by anaerobic digestion, in kilograms;
RQL,i,j = Estimated rate of manure production by livestock category j at facility i, calculated using Equation 5;
VSj = Volatile solids for livestock category j, determined in Table 1 in Appendix C, in kilograms per kilogram of manure;
B0,j = Maximum potential CH4 production for livestock category j, determined in Table 1 in Appendix C, in cubic metres of methane per kilogram of volatile solids.
Equation 5: Estimated rate of manure production for each livestock category, by agricultural facility
Where:
RQL,i,j = Estimated rate of manure production for livestock category j at facility i;
LFi,j = Fraction of livestock category j in the herd at facility i, using the value established for each case in the paragraphs below;
EFj = Excretion factor for livestock category j, determined in Table 1 in Appendix C, in kilograms per head per day;
k = Number of livestock categories at facility i;
j = Livestock category from Table 1 in Appendix C.
The fraction of a livestock category per facility (LF) is established as follows:
(1)  for cattle facilities, the promoter must determine the average percentage using the headcount for each livestock category in the herd, where the excrement is processed by anaerobic digestion during the reporting period;
(2)  for swine facilities, the promoter must determine the average percentage using the number of places for each livestock category in the herd, where the excrement is processed by anaerobic digestion during the reporting period.
