of COD in sludge transferred out of the sub‑facility and removed to a site other than landfill, measured in tonnes of COD.
            CODwz is the quantity of COD in wastewater entering the sub‑facility during the year, measured in tonnes of COD and calculated by using:

                (a) facility operating data that measures the volumetric influent rate and the influent rate of COD concentration; or
                (b) if data is available on the biochemical oxygen demand (BOD) in the wastewater—that data converted to COD in accordance with the following formula:

            EFslijz is the default methane emission factor for sludge with a value of 7.0 CO2‑e tonnes per tonne of COD (sludge).
            EFwijz is the default methane emission factor for wastewater with a value of 7.0 CO2‑e tonnes per tonne of COD.
            MCFslz is the methane correction factor for sludge treated at the sub‑facility during the reporting year.
            MCFwwz is the methane correction factor for wastewater treated at the sub‑facility during the reporting year.
            Qcapz has the same meaning as in step 1 in subsection (1).
            Qflaredz has the same meaning as in step 1 in subsection (1).
            Qtrz has the same meaning as in step 1 in subsection (1).
           Step 2. If the quantity worked out under step 1 is less than or equal to 1.00, work out CH4genz using the following formula:

            where:
            CODeffz has the same meaning as in step 1.
            CODslz has the same meaning as in step 1.
            CODtrlz has the same meaning as in step 1.
            CODtroz has the same meaning as in step 1.
            CODwz has the same meaning as in step 1.
            EFslijz has the same meaning as in step 1.
            EFwijz has the same meaning as in step 1.
            MCFwwz has the same meaning as in step 1.
            MCFslz has the same meaning as in step 1.
           Step 3. If the quantity worked out under step 1 is greater than 1.00, work out CH4genz using the formula:

            where:
            γ has the same meaning as in step 1 in subsection (1).
            Qcapz has the same meaning as in step 1 in subsection (1).
            Qflaredz has the same meaning as in step 1 in subsection (1).
            Qtrz has the same meaning as in step 1 in subsection (1).
 (3) For steps 1 and 2 in subsection (2), an operator of the plant must choose a treatment for MCFwwz and estimate the quantity of COD removed from the wastewater as sludge (CODslz).
 (4) For steps 1 and 2 in subsection (2), CODslz is worked out using the formula:
where:
CODpslz is the quantity of COD removed as primary sludge from wastewater and treated in the sub‑facility measured in tonnes of COD and may be estimated using the formula
