CAS 70879-47-9 Removed from Non‑domestic List

Summary#

This is an Order from the Department of the Environment under the Canadian Environmental Protection Act, 1999 that removes the chemical identified by CAS number 70879-47-9 from the Non‑domestic Substances List. The change is tied to the substance being added to the Domestic Substances List and will take effect when that related addition comes into force (see details below).

What it does#

• Removes the CAS number 70879-47-9 from Part I of the Non‑domestic Substances List.
• The Order was signed by Steven Guilbeault on January 27, 2025 and published in the Canada Gazette on February 15, 2025.
• The deletion becomes effective on the same day that subsection 1(1) of Order 2025-87-02-01 Amending the Domestic Substances List comes into force. If this Order is registered after that day, it comes into force on the day it is registered.

Who's affected#

• Manufacturers, importers, or users of the substance listed as 70879-47-9 in Canada are the most likely to notice this change.
• Federal regulators and anyone tracking which substances are classified as domestic versus non‑domestic will be affected.
• The notice does not give a chemical name, only the CAS number 70879-47-9, so it may be unclear to members of the public which product or industry this refers to without further lookup.

Why it matters#

• Being on the Domestic Substances List rather than the Non‑domestic Substances List changes how a substance is tracked and managed under federal chemical rules. This can affect reporting, assessment and regulatory attention.
• If you handle chemicals, suppliers or regulators, you may need to check whether this CAS number applies to your products or processes and whether any compliance steps change when the move to the Domestic List takes effect.
• The public may want to know the chemical identity behind 70879-47-9 to judge any local or environmental relevance; the Gazette notice gives only the CAS number, so further lookup or contact with the Department of the Environment would be needed to learn more.
