18  Calculating baseline emissions using sampling from deep open anaerobic lagoons

       The baseline emissions for a project treatment facility for a reporting period, EB, t, in tonnes CO2-e, are worked out using the following formula (equation 2):

       where:

       t is a project treatment facility.

       CODIn, Tot, t means the amount of chemical oxygen demand in the eligible wastewater for the project entering anaerobic digesters at project treatment facility t during the reporting period, in tonnes, worked out in accordance with the monitoring requirements.

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

       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.

       FEff, l means the fraction of CODIn, Tot, t that would have been removed in effluent and not undergone treatment in deep open anaerobic lagoon l to produce methane, worked out in accordance with section 19.

       FSlu, l means the fraction of CODIn, Tot, t that would have been in sludge and not undergone treatment in deep open anaerobic lagoon l to produce methane, worked out in accordance with section 22.

       UF means the conservativeness factor, which is 0.89.

       MCF means the default methane correction factor for deep anaerobic lagoons, set out in Part 5.3 of the NGER (Measurement) Determination.

       EF means the default methane emission factor for wastewater, in tonnes CO2-e per tonne COD, set out in Part 5.3 of the NGER (Measurement) Determination.
