6     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.
 3.73LB Method 2—onshore natural gas production, other than emissions that are vented or flared—onshore gas gathering and boosting pipelines
 (1) For section 3.73L and subsection 3.73M(1), Eijp is given by the following formula:

  Eijp = ∑k Tik × Pk × EFijk × Sij /SDij

where:
Eijp is the fugitive emissions (other than emissions that are vented or flared) of gas type (j), being methane or carbon dioxide, from the natural gas gathering and boosting pipelines during the year measured in CO2‑e tonnes.
Σk is the total emissions of gas type (j), being methane or carbon dioxide, measured in CO2‑e tonnes and estimated by summing up the emissions released from each equipment type (k) specified in column 2 of an item in the table in subsection (2), if the equipment is used in natural gas gathering and boosting.
Tik is the average hours of operation during the year of the equipment of each equipment type (k) specified in column 2 of the table in subsection (2), if the equipment is used in natural gas gathering and boosting during the year.
Pk is the length of the system of gathering and boosting pipelines of type (k) during the year measured in kilometres and used in natural gas gathering and boosting.
EFijk is the emission factor for gas type (j), being methane or carbon dioxide, measured in CO2‑e tonnes per kilometre‑hour of pipeline type (k), if the equipment is used in natural gas gathering and boosting.
Sij  is the measured share of each gas type (j), being methane or carbon dioxide, in the unprocessed gas (i), by volume, that passes though the equipment 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) For EFijk in subsection (1), column 3 of an item in the following table specifies the emission factor for methane (j) for an equipment type (k) specified in column 2 of that item and column 4 of an item in the following table specifies the emission factor for carbon dioxide (j) for an equipment type (k) specified in column 2 of that item:
Item  Equipment type (k)                                                Emission factor for gas type  (j)
