measured in tonnes of nitrogen and worked out as follows:

Noutdisij is the quantity of nitrogen leaving the plant, differentiated by discharge environment; or
 (b) for any other kind of wastewater treatment plant, using the following formula:

where:
Protein is the annual per capita protein intake of the population being served by the plant, measured in tonnes per person.
FracPr is the fraction of nitrogen in protein.
P is the population serviced by the plant during the year.
Ntrl is the quantity of nitrogen in sludge transferred out of the plant and removed to landfill during the year, measured in tonnes of nitrogen and worked out as follows:

where:
FNtrl is the fraction of nitrogen in the sludge transferred out of the plant.
Mtrl is the dry mass of sludge transferred out of the plant to landfill during the year, measured in tonnes.
Ntro is the quantity of nitrogen in sludge transferred out of the plant and removed to a site other than landfill during the year, measured in tonnes of nitrogen and worked out as follows:

where:
FNtro is the fraction of nitrogen in the sludge transferred out of the plant to a site other than landfill.
Mtro is the dry mass of sludge transferred out of the plant to a site other than landfill during the year, measured in tonnes.
Noutdisij is the quantity of nitrogen leaving the plant, differentiated by discharge environment.
EFsecij is the emission factor for wastewater treatment.
EFdisij is the emission factor for nitrogen discharge, differentiated by the discharge environment.
 (2) For Protein in subsection (1), the annual per capita protein intake is 0.036 tonnes per year.
 (3) For FracPr in subsection (1), the factor is 0.16 tonnes of nitrogen per tonne of protein.
 (4) For FNtrl and FNtro in subsection (1), the factor is 0.05.
 (5) For Noutdisij in subsection (1), discharge environments mentioned in column 2 of an item of the following table are defined in column 3 for the item.
