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 — 2025, 2026 and 2027. Information for the 2025 calendar year must be submitted by June 1, 2026. Information for the 2026 calendar year must be submitted by June 1, 2027. Information for the 2027 calendar year must be submitted by June 1, 2028.

Users of this notice should take note of the changes to reporting requirements, as described below, which are in effect as of the 2025, 2026 and 2027 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.

New requirements for reporting triarylmethane dyes

Additions to Part 1, Group B, with a 100 kg manufactured, processed, or otherwise used (MPO) threshold and 1% concentration threshold for each substance:

• Basic Violet 3, CAS RN 548-62-9
• Basic Violet 4, CAS RN 2390-59-2
• Basic Blue 7, CAS RN 2390-60-5

C.I. Basic Green 4 (CAS RN 569-64-2) was deleted from Part 1, Group A, and added to Part 1, Group B, with a MPO threshold of 100 kg and 1% concentration threshold. C.I. Basic Green 4 was renamed Malachite Green.

New requirements for reporting benzothiazoles that can form 2-mercaptobenzothiazole

2-Mercaptobenzothiazole (CAS RN 149-30-4) was deleted from Part 1, Group A, of the substance list. A group of 20 benzothiazoles that can form 2-mercaptobenzothiazole (MBT), including MBT, was added to Part 1, Group B, of the substance list with a 100 kg MPO threshold and a 0.1% concentration by weight threshold. The thresholds apply to the total of the 20 substances.

New requirements for reporting long-chain aliphatic amines

Ninety-two long-chain aliphatic amines were added to Part 1, Group B, of the substance list with a MPO threshold of 5 000 kg and a concentration threshold of 0.1% by weight. The thresholds apply to the total of the 92 substances.

New requirements for reporting hydrogen cyanide, free cyanide, cyanide salts and cyanide complexes

Free cyanide, cyanide salts and cyanide complexes were added to Part 1, Group B, of the NPRI substance list with a 1 000 kg MPO threshold and 0.1% concentration by weight threshold. The thresholds apply to the total of the group of substances. Hydrogen cyanide (CAS RN 74-90-8) was deleted from Part 1, Group A, and added to Part 1, Group B, of the substance list with a MPO threshold of 1 000 kg and 0.1% concentration.

New requirements for reporting per- and polyfluoroalkyl substances

One hundred sixty-three per- and polyfluoroalkyl substances (PFAS) were added to a new Part 1, Group C, of the substance list. Facilities that meet the employee threshold and that manufacture, produce, or otherwise use 1 kg or more of a listed PFAS at a concentration of 0.1% by weight or more will be required to report quantities of that PFAS that are released, disposed of and recycled. The mass and concentration thresholds apply to each listed PFAS individually.

New requirements for reporting ethylene oxide

Ethylene oxide (CAS RN 75-21-8) was deleted from Part 1A and added to Part 1B of the NPRI substance list, with a MPO threshold of 1 kg and a 0.1% concentration. In addition, the reporting requirements for ethylene oxide now apply to activities related to the education and training of students.

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 7 500 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 subsections 272(1) and 272.1(1) 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. Subsections 272.1(2), (3) and (4) of the Act set out the penalties for persons who contravene section 46 of the Act (compliance with the notice) or negligently provide false or misleading information. Subsections 272(2), (3) and (4) set out the penalties for knowingly providing false or misleading information. Penalties for a first offence under subsection 272(1) include fines of up to $1,000,000 for an individual and $6,000,000 for a corporation. Penalties for a first offence under subsection 272.1(1) include fines of up to $100,000 for an individual and $500,000 for a corporation. 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.
