Environment Canada Publishes Advisory Note Regarding Nanomaterials

Posted on July 24, 2007 by Lynn L. Bergeson
Environment Canada (EC) recently posted a New Substances Program Advisory Note entitled “Requirements for nanomaterials under the New Substances Notification Regulations (Chemicals and Polymers).” The Advisory Note was signed in June 2007 and states that the Canadian Environmental Protection Act, 1999 (CEPA) and the New Substances Notification Regulations (Chemicals and Polymers) (Regulations) “apply to new nanomaterials just as any other substance, whether a chemical or a polymer.

The Note includes the following questions and answers:

What are the requirements under the Regulations for nanomaterials which are manufactured or imported?

Nanomaterials which are manufactured in or imported into Canada are subject to the same regulatory requirements as chemicals and polymers, and notifiers must submit a New Substances Notification package prior to the manufacture in or import into Canada of the new substance.

Although not required, Environment Canada and Health Canada recommend notifiers request a Pre-notification Consultation (PNC) during the planning or preparation of a notification. For example, a notifier can request a PNC to assist with determining whether the substance is notifiable, as well as to clarify notification procedures or information requirements, and to determine the acceptability of waiver requests and/or test protocols.

What nanomaterials are subject to the Regulations?

Nanomaterials which are manufactured in or imported into Canada that are not listed on the Domestic Substances List (DSL) are considered new. The nanoscale form of a substance on the DSL is considered a “new” substance if it has unique structures or molecular arrangements. New nanomaterials are subject to notification under the Regulations. For example, the nanomaterial fullerene (CAS No. 99685-96-8) is not listed on the DSL and is considered a “new” substance under the Regulations.

What nanomaterials are not subject to the Regulations?

Substances listed on the DSL whose nanoscale forms do not have unique structures or molecular arrangements are considered existing. Existing nanomaterials are not subject to the Regulations and do not require notification. For example, titanium dioxide (CAS No. 13463-67-7) is listed on the DSL and since its nanoscale form does not have unique structures or molecular arrangements, it is not subject to the Regulations.

In addition, incidentally produced or naturally occurring nanomaterials are not subject to notification.

ED Will Hold Webcast on REACH, TSCA, and CEPA Best Practices

Posted on May 15, 2007 by Lynn L. Bergeson
Environmental Defense (ED) will hold a webcast regarding its recent report, Not That Innocent: A Comparative Analysis of Canadian, European Union and United States Policies on Industrial Chemicals, on May 24, 2007, from 3:00 p.m. to 4:30 p.m. (EDT). The webcast will include a 45-minute presentation and a question and answer period. Dr. Richard Denison, Senior Scientist at ED, will present the findings and discuss his report, which compares the European Union’s new Registration, Evaluation, and Authorization of Chemicals (REACH) regulation, the Toxic Substances Control Act (TSCA), and the Canadian Environmental Protection Act (CEPA).

Best practices for and a comparison of how each of these policies addresses the following “core functions” will be presented:

  • Identify and prioritize chemicals of concern;
  • Track chemicals and their production and use;
  • Foster the generation and submission of risk-relevant information;
  • Assess information to determine hazard/exposure/risk;
  • Impose controls to mitigate risk; and
  • Share and disclose information while protecting confidential business information.

Implications of the findings for chemicals policy reform will also be discussed.

To participate, contact Cathy Malina by COB May 22, 2007. Details and a toll-free call-in number will then be forwarded prior to the call. In addition to a telephone line, Internet access is needed to view presentation materials. If this is not possible, please advise Ms. Malina so alternative arrangements can be made.
