The NPI contains data on 93 priority substances which are emitted to the environment. The substance list has been determined by consideration of the potential impacts of substances on health and the environment.
There are three tables which relate to substances listed for reporting to the NPI.
- Table 1- substances are currently required to be reported if a facility exceeds substance reporting thresholds.
- Table 2- substances were required to be reported from 1 July 2001 to 1 July 2007.
- Table 3 - substances were required to be reported for the first three NPI reporting years.

More information about reporting some NPI substances.
- In this Schedule:
- the threshold for category 1 acids refers to the amount of the acid compound used (for example, in the case of Hydrochloric acid, the threshold refers to the amount of hydrogen chloride used). This amount can be calculated as a factor of volume and concentration;
- the thresholds for'Total Nitrogen' and 'Total Phosphorus' refer only to the amounts of those Nitrogen and Phosphorus compounds that give rise to nitrate/nitrite and phosphate ions respectively and, for transfers, the thresholds of 'Total Nitrogen' and 'Total Phosphorus' refer only to the amounts of soluble compounds of Nitrogen and Phosphorus that are in materials that readily permit the dissolution of these substances;
- the threshold for Ammonia (total) refers to the total amount of both ammonia (NH3 CAS number 7664-41-7) and the ammonium ion (NH4+) in solution;
- the threshold for 'Chlorine & compounds' includes the amount of chlorine compounds used which may produce emissions of chlorine gas (Cl2), free residual chlorine, hypochlorite ion (OCl-), hypochlorous acid (HOCl) or chloramines;
- the threshold for category 1 or category 1b substances that are listed as '(a metal) & compounds' refers to the total amount of the metal and its compounds used (for example, 'Lead & compounds' refers to Lead and all compounds which incorporate Lead);
- For the purposes of estimating emission and mandatory transfer data to be reported under clause 9 of the Measure:
- the amount of a category 1 acid emitted refers to the amount of the actual acid compound emitted (for example, in the case of Hydrochloric acid, the amount emitted refers to the amount of hydrogen chloride emitted). It does not include any amounts of the acid that have been neutralised before release as the acid no longer exists;
- the amounts of 'Total Nitrogen' and 'Total Phosphorus' emitted or transferred refer to the amounts of those nitrogen and phosphorus compounds emitted or transferred that give rise to nitrate/nitrite and phosphate ions respectively and, for transfers, the amounts of 'Total Nitrogen' and 'Total Phosphorus' transferred refer only to the amounts of soluble compounds of nitrogen and phosphorus that are in materials that readily permit the dissolution of these substances;
- the amount of 'Ammonia (total)' emitted or transferred refers to the total amount of both ammonia (NH3 CAS number 7664-41-7) and the ammonium ion (NH4+) emitted or transferred in solution;
- the amount of 'Chlorine & compounds' emitted or transferred refers to the total amount of chlorine gas (Cl2), free residual chlorine, hypochlorite ion (OCl-), hypochlorous acid (HOCl) and chloramines emitted or transferred, expressed as the equivalent weight of chlorine (Cl);;
- the amount emitted in relation to a substance listed as (a metal) & compounds refers only to the amount of the metal emitted (for example, the amount of Lead & compounds emitted refers only to the amount of Lead emitted);
- the amount of 'Polychlorinated Dioxins and Furans (TEQ)' emitted or transferred refers to the sum of the toxic equivalent amounts of the individual congeners emitted. Toxic equivalent amounts are obtained by multiplying the mass of the congener by the Toxicity Equivalency Factor published in industry reporting materials;
- the amount of 'Polycyclic Aromatic Hydrocarbons (Benzo[a]pyrene equivalent) (PAHs B[a]Peq)' emitted refers to the sum of the toxic equivalent amounts of the individual congeners emitted or transferred. Toxic equivalent amounts are obtained by multiplying the mass of the congener by the Toxicity Equivalency Factor published in industry reporting materials;
- the amount of 'Oxides of Nitrogen' emitted refers to the mass of Nitrogen oxide and Nitrogen dioxide expressed as the equivalent mass of Nitrogen dioxide according to the protocol published in industry reporting materials;
- the amount of 'Particulate Matter ≤2.5 µm (PM2.5)' emitted refers only to the amount emitted from the burning of fuel or waste.

- In this Schedule:
- the threshold for category 1 acids refers to the amount of the acid compound used (for example, in the case of Hydrochloric acid, the threshold refers to the amount of hydrogen chloride used). This amount can be calculated as a factor of volume and concentration;
- the thresholds for total Nitrogen and total Phosphorus refer only to the amounts of those Nitrogen and Phosphorus compounds that give rise to nitrate/nitrite and phosphate ions respectively;
- the threshold for Ammonia (total) refers to the total amount of both ammonia (NH3 CAS number 7664-41-7) and the ammonium ion (NH4+) in solution;
- the threshold for Chlorine includes the amount of hypochlorite and like substances used;
- the threshold for category 1 substances that are listed as (a metal) compounds refers to the total amount of the metal and its compounds used (for example, Lead & compounds refers to Lead and all compounds which incorporate Lead);
- the threshold for Phenol (CAS number 108-95-2) refers, at the discretion of the reporting facility, to either the total amount of phenolic compounds used or the total amount of phenol used.
- For the purposes of estimating emission data to be reported under clause 9 of the Measure:
- the amount of a category 1 acid emitted refers to the amount of the actual acid compound emitted (for example, in the case of Hydrochloric acid, the amount emitted refers to the amount of hydrogen chloride emitted). It does not include any amounts of the acid that have been neutralised before release as the acid no longer exists;
- the amounts of total Nitrogen and total Phosphorus emitted refer to the amounts of those Nitrogen and Phosphorus compounds emitted that give rise to nitrate/nitrite and phosphate ions respectively;
- the amount of Ammonia (total) emitted refers to the total amount of both Ammonia (NH3 CAS number 7664-41-7) and the ammonium ion (NH4+) emitted in solution;
- the amount of Chlorine emitted refers only to the amount chlorine (Cl CAS number 7782-50-5) emitted;
- the amount emitted in relation to a substance listed as (a metal) & compounds refers only to the amount of the metal emitted (for example, the amount of Lead & compounds emitted refers only to the amount of Lead emitted);
- the amount of Phenol (CAS number 108-95-2) emitted refers, at the discretion of the reporting facility, to either the total amount of phenolic compounds emitted or the total amount of Phenol emitted.
