23 Chemical oxygen demand in sludge in a deep open anaerobic lagoon
(1) The amount of chemical oxygen demand in sludge in deep open anaerobic lagoon l in the historical period of sampling (which is 1 year), CODSlu, l (in tonnes), is worked out in accordance with this section.
(2) For sludge produced from the treatment of domestic or commercial wastewater, the amount is equivalent to parameter CODslz calculated under Division 5.3.3 of the NGER (Measurement) Determination, with the following modifications:
(b) parameter CODslz applies as if a reference to the quantity of COD removed as sludge (however described) from wastewater and treated in a sub facility were a reference to the quantity of COD in sludge produced in deep open anaerobic lagoon l for project treatment facility t in the historical period of sampling.
(3) For sludge produced from the treatment of industrial wastewater, the amount is equivalent to parameter CODsl calculated under Division 5.4.3 of the NGER (Measurement) Determination, with the following modifications:
(b) parameter CODsl applies as if:
(i) a reference to the quantity of COD removed as sludge from wastewater during a year were a reference to the quantity of COD in sludge produced in deep open anaerobic lagoon l for project treatment facility t in the historical period of sampling; and
(ii) parameter CODw,i (as described in subsection 5.43(2) of the NGER (Measurement) Determination) applies in the same way as described in subsection 21(3).
