21 Chemical oxygen demand in influent entering a deep open anaerobic lagoon
(1) The amount of chemical oxygen demand in influent entering deep open anaerobic lagoon l in a historical period of sampling, CODIn, l (in tonnes), is worked out in accordance with this section.
(2) For influent that is domestic or commercial wastewater, the amount is equivalent to parameter CODwz calculated under Division 5.3.3 of the NGER (Measurement) Determination, with the following modifications:
(b) if the historical period of sampling is 10 consecutive days—the reference to a monthly basis in section 5.29 of that Determination is taken to be a reference to a daily basis;
(c) parameter CODwz applies as if:
(i) a reference to “the sub facility during the year” were a reference to “deep open anaerobic lagoon l for project treatment facility t in the historical period of sampling”; and
(3) For influent that is industrial wastewater, the amount is equivalent to parameter CODw,i calculated under Division 5.4.3 of the NGER (Measurement) Determination, with the following modifications:
(b) if the historical period of sampling is 10 consecutive days—the reference to a monthly basis in section 5.46 of that Determination is taken to be a reference to a daily basis;
(c) parameter CODw,i (as described in subsection 5.43(2) of the NGER (Measurement) Determination) applies as if:
(i) a reference to “the plant” were a reference to “deep open anaerobic lagoon l for project treatment facility t in the historical period of sampling”; and
