19  Amount of captured methane
 (1) The amount of methane captured for permanent storage by the project during a reporting period in the crediting period, in tonnes CO2-e, is worked out using the formula (equation 4):
  QCM  =  ∑n ((VolCH4,n  ×  γ)  –  ECH4,n)
  where:
  QCM means the amount of methane captured for permanent storage by the project during the reporting period, in tonnes CO2-e.
  VolCH4,n means the amount of methane captured for permanent storage by the project during the reporting period at a capture point n, in cubic metres, worked out as follows:
 (a) if the capture point does not relate to oil or natural gas production or processing—zero;
 (b) if the capture point relates to oil or natural gas production or processing and, in the absence of the project, the methane captured at the capture point would not be converted to carbon dioxide prior to release into the atmosphere—zero;
 (c) if the capture point relates to oil or natural gas production or processing and, in the absence of the project, the methane captured at the capture point would be converted to carbon dioxide prior to release into the atmosphere—the amount of methane captured for permanent storage by the project at the capture point during the reporting period, measured in cubic metres in accordance with subsection (2).
  γ means the factor for converting a quantity of methane from cubic metres at standard conditions of pressure and temperature to CO2-e tonnes, being 6.784 × 10-4 × GWPCH4.
  ECH4,n means:
 (a) if the value for VolCH4,n for a capture point n for the reporting period is determined in accordance with paragraphs (a) or (b) of the definition of VolCH4,n—zero;
 (b) if the value for VolCH4,n for a capture point n for the reporting period is determined in accordance with paragraph (c) of the definition of VolCH4,n—the emissions that would have occurred if the amount of methane comprised in that value for VolCH4,n had been combusted, in tonnes CO2-e, calculated in accordance with section 2.20 of the NGER (Measurement) Determination.
  n means a capture point used by the project.
 (2) For paragraph (c) of the definition of VolCH4,n in subsection (1), the amount of methane must be measured:
 (a) in a manner that:
               (i) is consistent with the requirements in subsections 1.19E(3), (4), (5) and (6) of the NGER (Measurement) Determination; and
               (ii) is consistent with criterion AAA set out for the measurement of captured greenhouse gas stream in section 1.19G of that determination, converted at standard conditions of pressure and temperature; and
               (iii) assumes references to the greenhouse gas stream in those provisions to be references to methane captured at a capture point n for permanent storage by the project; or
