8.7  Assessment of uncertainty for estimates of methane and nitrous oxide emissions from combustion of fuels
 (1) In assessing uncertainty of the estimates of methane and nitrous oxide emissions estimated using method 1 for a source that involves the combustion of a fuel specified in column 2 of an item in the table in subsection 8.6(1):
 (a) the uncertainty level of the energy content factor is:
 (i) as specified in column 3 for the item; or
 (ii) as worked out in accordance with section 7 of the uncertainty protocol; and
 (b) the uncertainty level of the emissions factor is:
 (i) 50%; or
 (ii) as worked out in accordance with section 7 of the uncertainty protocol.
 (2) In assessing uncertainty of the estimates of methane and nitrous oxide emissions estimated using method 1 for a source that involves the combustion of a fuel type specified in column 2 of an item in the table in subsection 8.6(3):
 (a) column 3 for the item sets out the uncertainty level for the estimated quantities of fuel combusted using criterion A in Chapter 2; and
 (b) column 4 for the item sets out the uncertainty level for the estimated quantities of fuel combusted using criterion AA in Chapter 2; and
 (c) column 5 for the item sets out the uncertainty level for the estimated quantities of fuel combusted using criterion AAA in Chapter 2; and
 (d) column 6 for the item sets out the uncertainty level for the estimated quantities of fuel combusted using criterion BBB in Chapter 2.
Note: Division 2.2.5 sets out the relevant criteria for solid fuels; Division 2.3.6 sets out the relevant criteria for gaseous fuels; and Division 2.4.6 sets out the relevant criteria for liquid fuels.

8.8  Assessment of uncertainty for estimates of fugitive emissions
  The aggregated uncertainty of the estimates of fugitive emissions estimated using method 1 for a source mentioned in column 2 of an item of the following table is:
 (a) as specified in column 3 for the item; or
 (b) as worked out in accordance with the uncertainty protocol.
