20  Chemical oxygen demand in effluent leaving a deep open anaerobic lagoon

       (1) The amount of chemical oxygen demand in effluent leaving deep open anaerobic lagoon l in a historical period of sampling, CODEff, l, in tonnes, is worked out in accordance with this section.

       (2) For effluent that is domestic or commercial wastewater, the amount is equivalent to parameter CODeffz calculated under Division 5.3.3 of the NGER (Measurement) Determination, with the following modifications:
          (a) paragraphs 5.28(1)(c) and (2)(c) of that Determination are taken to be omitted;
          (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 CODeffz applies as if:
 (i) a reference to "the sub facility during the reporting year" were a reference to "deep open anaerobic lagoon l for project treatment facility t in the historical period of sampling"; and
 (ii) a reference to "facility operating data" were a reference to "data about the operation of lagoon l".

       (3) For effluent that is industrial wastewater, the amount is equivalent to parameter CODeff calculated under Division 5.4.3 of the NGER (Measurement) Determination, with the following modifications:
          (a) paragraphs 5.45(1)(c) and (2)(c) of that Determination are taken to be omitted;
          (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 CODeff applies as if a reference to "the plant during the year" were a reference to "deep open anaerobic lagoon l for project treatment facility t in the historical period of sampling".

        (4) In this section:

       t is a project treatment facility.

       l is a deep open anaerobic lagoon that is part of project treatment facility t and was replaced as part of the project.
