Triclocarban guideline and environment notices

Summary#

This Canada Gazette notice collects several Environment Department actions and reports published on March 16, 2024 by the Department of the Environment under the Canadian Environmental Protection Act, 1999. Key items include publication of federal guidelines for triclocarban, an interim order that freezes trailer-specific greenhouse‑gas rules, ministerial conditions allowing limited manufacture/import of live vaccinia virus Acambis clone 2000, and a draft health/environment assessment of 27 Low Boiling Point Naphthas.

What it does#

• Publishes the Federal Environmental Quality Guidelines for triclocarban (guidance document now available online).
• Issues the Interim Order Modifying the Operation of the Heavy-duty Vehicle and Engine Greenhouse Gas Emission Regulations (Trailer Standards):
  • Temporarily stops applying the trailer provisions of those regulations to trailers whose manufacture was completed on or after January 1, 2020.
  • The order was made on February 19, 2024 and is temporary (it will end if the regulation is changed, repealed, or after one year).
• Establishes Ministerial Condition No. 21722 for the living organism live vaccinia virus Acambis clone 2000:
  • Allows a specific notifier to manufacture or import the virus under strict containment, handling, record‑keeping and disposal rules.
  • Sets requirements like import/manufacture only in containment facilities, notification 120 days before starting manufacture, waste decontamination, and maintaining records for five years.
  • These conditions come into force on February 27, 2024.
• Releases a draft assessment and risk‑management scoping document for the Low Boiling Point Naphthas Group (27 substances):
  • Proposes that 17 of these substances (used in some consumer products) meet criteria for concern for human health and be recommended for listing on Part 2 of Schedule 1 to the Act.
  • Proposes no further action now for the other 10 substances that have no identified consumer uses.
  • Opens a public comment period of 60 days from publication.
• Lists ongoing Governor in Council appointment opportunities (with some closing dates such as April 16, 2024 for specified posts).

Who's affected#

• Manufacturers, importers and researchers who handle live vaccinia virus Acambis clone 2000, and the single notifier named in the notice. Also any facilities that would receive transfers of the organism.
• Trailer and heavy‑vehicle manufacturers, importers, and possibly fleet operators while the trailer standards are suspended.
• Companies that make or sell solvents and products that can contain Low Boiling Point Naphthas—examples in the notice include paints and coatings, adhesives and sealants, cosmetics, household cleaners, and automotive products.
• People living near industrial sites that use or release these petroleum solvents, and consumers who use products containing them.
• Citizens and organizations who want to comment on the LBPN draft assessment (open for 60 days).
• Canadians interested in federal Governor in Council appointments.

If any part of who is affected is unclear from the notice, the Gazette text indicates uncertainty and points readers to the full documents on Canada.ca for details.

Why it matters#

• The trailer‑standards interim order removes the immediate legal effect of trailer‑specific GHG rules. That can change regulatory obligations for trailer makers and could affect how emissions from trailers are managed or regulated in the short term.
• The ministerial conditions for the vaccinia virus set out detailed containment and safety steps. That allows controlled manufacture or import while aiming to limit any risk to the environment or public health.
• The LBPN draft assessment flags potential health concerns for certain solvent groups used in consumer products. If the proposed listing and risk management proceed, manufacturers may face new controls or restrictions, and some consumer products could be reformulated or relabeled.
• The public has a chance to comment on the LBPN proposals within 60 days of publication, which is a step where industry, health groups, and citizens can influence next steps.
