EXPLANATORY NOTE

(This note is not part of the notice.)

Users should take note that this notice sets out the requirements for reporting to the NPRI for three individual calendar years — 2022, 2023 and 2024. Information for the 2022 calendar year must be submitted by June 1, 2023. Information for the 2023 calendar year must be submitted by June 3, 2024. Information for the 2024 calendar year must be submitted by June 2, 2025.

Users of this notice should take note of the changes to reporting requirements, as described below, which are in effect as of the 2022, 2023 and 2024 calendar years. Consultations were undertaken with respect to these changes. Information on the rationale for these changes is available on the NPRI website or by contacting the NPRI.

Deletion of substances

Two substances have been deleted from the Part 1, Group A, list:

Hexachlorocyclopentadiene (CAS RN 77-47-4)
Methyl iodide (CAS RN 74-88-4)

Addition of a substance

One substance has been added to the Part 1, Group B list:

Chlorhexidine and its salts (CAS RN 55-56-1)

Changes that apply to all substances

Facilities are now required to indicate the reason a substance is being reported for the first time.

Facilities are now required to report any applicable identification number for their provincial or territorial operating permit, approval, authorization, licence, or certificate or any other applicable provincial or territorial environmental program identifier.

Two new bases of estimate have been added to the list of bases of estimate that facilities are permitted to use to estimate substance quantities: remote quantification and speciation profile.

The names of three categories of air releases have been changed:

“Storage or handling releases” has been changed to “storage tank and related handling releases.” Releases that are not associated with storage tanks that were previously reported under this category will now be reported as stack or point releases or fugitive releases.
“Spills” has been changed to “spills or other accidental releases.” This is a change to the name only — releases that were previously reported under this category will continue to be reported under this category.
“Road dust” has been changed to “unpaved road dust.” This is a change to the name only — releases that were previously reported under this category will continue to be reported under this category.

Facilities are strongly encouraged to determine how their releases fit into the five release categories (stack or point releases, storage tank and related handling releases, fugitive releases, spills or other accidental releases, and unpaved road dust) and to not report releases under the “Other non-point releases” category. Facilities reporting releases under the “Other non-point releases” category are now required to provide a comment specifying the nature of the releases.

Change to an exemption for Parts 1 to 3 substances

The exemption from reporting Parts 1 to 3 substances from “research and testing” activities has been reworded to “research and development.” This is a change in wording only — the exempted activities remain the same, and the new wording is intended to clarify the activities to which it applies.

Changes to the requirements for reporting Part 4 substances

Changes have been made to the requirements for Part 4 criteria air contaminants (CACs) in order to increase individual stack reporting. The changes include lowering the stack height threshold from 50 m above grade to 25 m above grade; increasing the stack air release thresholds for six of the seven CACs; adding a stack exit temperature threshold; and adding exemptions from reporting of individual stacks for certain types of stacks and facilities. In order to increase the information available on sources of CAC emissions, a requirement has been added to break down individual stack releases into several categories of combustion and fuel use activities, and to report the fuel types and basis of estimate associated with each category.

The name of the Part 4 substance “volatile organic compounds” has been changed to “volatile organic compounds (total).” Only the substance name has been changed — the reporting requirements for this substance have not been changed, other than the changes to individual stack reporting described above.

Facilities reporting stack or point releases of PM_2.5, PM₁₀ or total particulate matter must now indicate if their reported releases include condensable particulate matter. Note that only filterable particulate matter is required to be reported. However, some facilities may need to use a method of quantification that includes both condensable and filterable particulate matter, and may not be able to separate out only the filterable fraction. Those facilities will be required to indicate this with their report.

Changes to the requirements for reporting Part 5 substances

Changes have been made in order to simplify the requirements for reporting Part 5 speciated volatile organic compounds (VOCs). The 10-tonne total VOCs threshold no longer applies to reporting speciated VOCs. Instead, a speciated VOC must be reported if 1 tonne or more of that speciated VOC is released from the facility. The 5-tonne total VOCs threshold no longer applies to reporting speciated VOCs from an individual stack. Instead, a speciated VOC must be reported for an individual stack if 0.25 tonnes or more of that speciated VOC is released from the stack. In addition, a basis of estimate must now be provided for speciated VOCs.

The National Pollutant Release Inventory — Background information

The NPRI is Canada’s legislated, publicly accessible inventory of pollutant releases, disposals and recycling. It includes information collected from facilities under the authority of section 46 of the Canadian Environmental Protection Act, 1999 (the “Act”).

The Act contains information-gathering provisions that allow the Minister of the Environment to require reporting of information on certain substances. The provisions also require the Minister to establish and publish a national inventory of releases of pollutants. These provisions under the Act form the primary legislative basis for the NPRI.

For the latest reporting year, over 7 300 industrial, commercial and other facilities reported to Environment and Climate Change Canada on their releases, disposals and transfers for recycling of more than 300 substances of concern.

The NPRI is a key part of the Government of Canada’s efforts to track toxic substances and other substances of concern. It is a key tool for identifying and monitoring sources of pollution in Canada, as well as for developing indicators for the quality of air, water and land. Information collected through the NPRI is used as part of the comprehensive Air Pollutant Emissions Inventory, is used to calculate emissions for the Black Carbon Emissions Inventory, supports chemicals management initiatives, and is made publicly available to Canadians each year. Public access to the NPRI motivates industry to prevent and reduce pollutant releases. NPRI data helps the Government of Canada to track progress in pollution prevention, evaluate releases and transfers of substances of concern, identify environmental priorities, conduct air quality modelling, and implement policy initiatives and risk management measures.

For more information on the NPRI, including guidance documents, annual data highlights and overview reports, and access to the NPRI data in a variety of formats, including an online search and databases, please visit the NPRI website.

Input from stakeholders and other interested parties on the NPRI is welcome. Contact information is provided at the beginning of this notice.

Reporting to the National Pollutant Release Inventory

Reporting requirements outlined in this notice are collected via Environment and Climate Change Canada’s Single Window reporting system.

For those who meet the requirements of this notice, reporting is mandatory. Obtaining the relevant guidance documents is the responsibility of the person required to report under this notice. Visit the NPRI website or contact Environment and Climate Change Canada at the address provided at the beginning of this notice for guidance documents.

Changes to contacts, ownership and reported information

It is important that contact and ownership information be kept up to date and any errors in submitted data be corrected in a timely manner, so that the information provided by the NPRI continues to be relevant and accurate. Therefore, persons who submitted reports for a previous year are strongly encouraged to update their information, through the Single Window reporting system or by contacting Environment and Climate Change Canada directly, if

there has been a change in the name, telephone number, or email address of the contacts identified for the facility since the submission of the report for the previous year;
there is a change in the owner or operator of a facility for which a report has been submitted for the previous year; or
the person becomes aware that the information submitted for any previous year was mistaken or inaccurate.

If a person is providing an update to previously submitted information, the person should indicate the reason the information is being updated.

Obligation to comply with the Canadian Environmental Protection Act, 1999

Compliance with the Act is mandatory and specific offences are established by subsection 272.1(1) of the Act. Subsections 272.1(2), (3) and (4) of the Act set the penalties for persons who contravene section 46 of the Act. Offences include the offence of failing to comply with an obligation arising from the present notice and the offence of providing false or misleading information. Penalties include fines, and the amount of the fine can range from a maximum of $25,000 for an individual convicted following summary proceedings to a maximum of $500,000 for a large corporation convicted on indictment. The maximum fines are doubled for second or subsequent offences.

The current text of the Act, including the most recent amendments, is available on Justice Canada’s website.

The Act is enforced in accordance with the compliance and enforcement policy for the Canadian Environmental Protection Act, 1999. Suspected violations under the Act can be reported to the Enforcement Branch by email at enviroinfo@ec.gc.ca.
