Each year, Environment Canada updates the NPRI substance list and revises reporting criteria after consultation with stakeholders. The NPRI currently tracks over 300 substances or groups of substances.
The Goals of NPRI are to:
- provide Canadians with access to pollutant release information for
facilities located in their communities
- assist governments and others in identifying priorities for action
- encourage industry to take voluntary measures to reduce releases
- allow for tracking of progress in the reduction of releases
- support a number of regulatory initiatives across Canada
The NPRI substances are broken into several Parts:
- Part 1
- Group 1 – General list of 232 substances and families
- Group 2 – Mercury
- Group 3 – Cadmium
- Group 4 – Lead, arsenic, Hex chrome, tetraethyl lead
- Part 2 – Polycycyclic Aromatic Hydrocarbons
- Part 3 – Dioxins & Furans, Hexachlorobenzene
- Part 4 – Criteria Air Contaminants
- Part 5 – Speciated Volatile Organic Compounds
In general, any person in Canada who owns or operates a non-exempt facility
is required to submit a report to the NPRI, if they meet all of the three
- employees worked a total of 20,000 hours or more (equivalent to 10
full-time employees) during the calendar year, and
- the facility manufactured, processed, or otherwise used 10 tonnes
(10,000 kg) or more of an NPRI substance in the calendar year including
- the NPRI substance was manufactured, processed or otherwise used at a
concentration greater than or equal to 1% by weight, with the exception of
NPRI substance considered to be by-products.
Note: There are a number of NPRI substances that have alternate
thresholds. These thresholds are substance specific and must be considered for
each facility and contaminant.
Note: There are a number of specific activities for which the 20,000
employee hours threshold does not apply.
What is required to be reported to the NPRI?
If the reporting criteria are met for an NPRI substance, then all releases of
the substance must be reported regardless of the concentration or amount and
include releases to:
- underground injection
- surface water
- land, and
- offsite transfers for disposal or recycling
Is there an overlap between main NPRI Listed Substances and Speciation VOCs?
A number of substances on the core NPRI list are also included on the VOC
Examples of some NPRI listed substances that are found both the MPO list and
VOC speciation list include:
- Methyl alcohol
