19  Fraction of chemical oxygen demand in influent removed in effluent

        The fraction of CODIn, Tot, t (within the meaning of section 18) that would have been removed in effluent and not undergone treatment in deep open anaerobic lagoon l to produce methane (FEff, l), is worked out using the formula (equation 3):

       where:

       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.

       CODEff, l means the amount of chemical oxygen demand in effluent leaving deep open anaerobic lagoon l in the historical period of sampling, in tonnes, worked out in accordance with section 20.

       CODIn, l means the amount of chemical oxygen demand in influent entering deep open anaerobic lagoon l in the historical period of sampling, in tonnes, worked out in accordance with section 21.

       AF means the adjustment factor based on the historical period of sampling that is used, which is:
          (a) if the historical period of sampling is 1 year—1; or
          (b) if the historical period of sampling is 10 consecutive days—1.12.
