41  Digestate emissions—treated in open lagoon

       The emissions from digestate from project treatment facility t treated in an open lagoon, EDig,t,Lag (in tonnes CO2-e), is worked out using the formula (equation 20):

       where:

       t is a project treatment facility.

       q is an open lagoon that receives volatile solids from project treatment facility t.

       EDig,t,Lag means the emissions from digestate from project treatment facility t treated in open lagoon q, in tonnes CO2-e.

       VSDig,t means the volatile solids discharged from an anaerobic digester at project treatment facility t into open lagoon q, in tonnes, worked out in accordance with the monitoring requirements.

            Note: Determination of VSDig,t,q requires the determination of parameter QDig,t,n for the digestate from treatment facility t where n is treatment in an open lagoon: see items 8 and 12 of the table in subsection 45(1).

       MMax,Dig,t means the maximum methane producing capacity of the digestate from project treatment facility t, sent to open lagoon q, in tonnes of methane per tonne of volatile solids, worked out in accordance with the monitoring requirements.

       MCFLag means the methane correction factor for open lagoon q, set out in Part 5.3 of the NGER (Measurement) Determination.

       GWPCH4  means the global warming potential value for methane, set out in regulation 2.02 of the National Greenhouse and Energy Reporting Regulation 2008.
