13  Subsection 3.73NB(1)
Repeal the subsection, substitute:

(1)  Method 2 is:

    Eij = (Wi × EFijw × Sij /SDij) - Qj,cap

   Where:

       Eij is the fugitive emissions (other than emissions that are vented or flared) of gas type (j) being methane from the produced water from the relevant activity during the year measured in CO2‑e tonnes.

       Wi is the net quantity of produced water during the year associated with the relevant activity measured in megalitres of produced water, where the net quantity is the total quantity of produced water during the year minus the total quantity of produced water not exposed to the atmosphere that is reinjected over the same period.

       EFijw is the emission factor for gas type (j), being methane, measured in CO2‑e tonnes per megalitre of produced water associated with the relevant activity during the year as determined under subsection (2).

       Sij  is the measured share of gas type (j) being methane 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 0.832.

       Qj,cap is the quantity of gas type (j), being methane from the produced water from the relevant activity captured during the year (before reaching the resource pond) and re-injected back into the gathering line, measured in CO2-e tonnes and estimated in accordance with Division 2.3.6.

       Note: The energy content of the quantity of methane in Qj,cap must be reported in the quantity of energy produced for the relevant fuel type. The additional energy produced carries through any subsequent energy transformations and processing.
