7     Dehydrators                                  2.00 × 10‑3                         4.96 × 10‑6  tonnes CO2‑e /equipment ‑ hour

 (b) if the manufacturer of the equipment supplies equipment‑specific emission factors for the equipment type—those factors are the relevant emissions factors.

       3.73C  Method 3—onshore natural gas production, other than emissions that are vented or flared—wellheads

 (1) Method 3 is:
Eij = ∑k (Tik × Nik ×EFijk ) × Sij /SDij
where:
Eij is the fugitive emissions (other than emissions that are vented or flared) of gas type (j), being methane or carbon dioxide, from the onshore natural gas production during the year measured in CO2‑e tonnes.
Σk is the total emissions of gas type (j), being methane or carbon dioxide, measured in tonnes of CO2‑e and estimated by summing up the emissions released from each component type (k), if the component type is used in the onshore natural gas production during the year.
EFijk is the emission factor of gas type (j), being methane or carbon dioxide, measured in tonnes of CO2‑e per component‑hour for each component type (k) as determined under subsection (2) or (3), if the component is used in the onshore natural gas production during the year.
Note: Consistent with subsection 3.41(2), emissions associated with any components included in this definition should not be counted under this section if those emissions are also counted as component emissions under another section within this Part.
Nik is the total number of components of each component type (k) if the component type is used in the onshore natural gas production during the year.
Tik is:
 (a) if subsection (2) applies—the average hours of operation during the year of the component of each component type (k), if the component is used in the onshore natural gas production;
 (b) if subsection (3) applies—an engineering estimate of the number of hours in the year the component type (k) was operational as a leaker or non leaker based on the best available data and subsection (4).
Sij  is the measured share of gas type (j), being methane or carbon dioxide, in the unprocessed gas (i), by volume, measured in accordance with Division 2.3.3 and the principles in section 1.13.
SDij is the default share of gas type (j) in the unprocessed gas (i), for methane SD is 0.788 and for carbon dioxide SD is 0.02.
 (2) Unless subsection (3) is elected and used for all components under this method, EFijk, the emission factors for methane or carbon dioxide (j), for component type (k), are:
 (a) column 3 of an item in the following table specifies the emission factor for methane (j) for a component type (k) specified in column 2 of that item and column 4 of an item in the
