Substance Groupings Initiative (2017)

The following four substances in this Batch have been included in the Cobalt-containing Substance Grouping under the Substance Groupings Initiative as part of the second phase of the Chemicals Management Plan (CMP). They were included in the Cobalt-containing Substance Grouping screening assessment to consider exposure to cobalt from multiple cobalt-containing substances. Updated information for these substances is available on the Cobalt-containing Substance Grouping webpage.

Risk management action milestones

The risk management action milestones table outlines the risk management actions that were proposed for the chemical substance in this batch of the Challenge that met the criteria of section 64 of the Canadian Environmental Protection Act, 1999 (CEPA 1999). These proposed risk management actions were published in the risk management approach document for this substance. For the complete wording of these proposed actions, please refer to the risk management approach document.

Adding substances to Schedule 1

One substance in this batch has been included in a final order to add to Schedule 1.

• Final order adding 1 substance: Canada Gazette, Part II: Vol. 146, No. 21 - October 10, 2012
  • Corresponding proposed order: Canada Gazette, Part I: Vol. 145, No. 9 - February 26, 2011

Applying Significant New Activity provisions

View the Significant New Activity Publications under the Canadian Environmental Protection Act, 1999.

Three substances in this batch were to be addressed through the application of Significant New Activity (SNAc) provisions. One Order and 2 notices of intent have been published. However, further analysis has indicated that due to its chemistry, hydrazine would only be present in a consumer product at low residual levels. As a result, there are no likely new exposure sources of hydrazine for the general population of Canada that would reasonably be suspected to lead to increased risks to human health. Therefore, this risk management instrument to address the human health concerns is no longer being pursued. An order amending the Domestic Substances List (DSL) for hydrazine will not be published. This decision is consistent with the Policy on the use of SNAc provisions of CEPA 1999, published in December 2013. For additional guidance on submitting information required as part of SNAc notifications, please see the Guidelines for the notification and testing of new substances: chemicals and polymers

• Order amending the DSL that applies to 1 substance: Canada Gazette, Part II: Vol. 145, No. 3 - February 2, 2011
  • Corresponding notice of intent: Canada Gazette, Part I: Vol. 144, No. 26 - June 26, 2010)
• Notice of intent amending the DSL that applies to 1 substance: Canada Gazette, Part I: Vol. 145, No. 3 - January 15, 2011
• No longer being pursued: notice of intent amending the DSL that applies to 1 substance: Canada Gazette, Part I: Vol. 147, No. 9, March 2, 2013

Summary of Batch 10 substances and publications

Final screening assessments and risk management approaches

In January 2011, the final screening assessments for substances in this batch were released in the Canada Gazette, Part I: Vol. 145, No. 3 - January 15, 2011.

The final screening assessments concluded that 1 substance in this batch meets one or more criteria in section 64 of the CEPA 1999. The Government proposed to add this substance to Schedule 1 of the act. A proposed risk management approach document was also released on this date for the substance in this batch which met the criteria in section 64 of CEPA 1999.

In May 2017, 4 substances in this batch (CAS RNs 7440-48-4, 7646-79-9, 10124-43-3 and 10393-49-4) were included in a screening assessment of a broader group of cobalt-containing substances as part of the Substance Groupings Initiative. The 2017 assessment concluded that cobalt and soluble cobalt compounds are harmful to the environment. Updated information for these substances is available on the Cobalt-containing Substance Grouping web page.

Draft screening assessments and risk management scopes

New information was received from industry or interested stakeholders for each of the 18 substances in this batch. In June 2010, the draft screening assessments were released and the related notices were published in the Canada Gazette, Part I: Vol. 144, No. 26 - June 26, 2010. Risk management scope documents were also released in conjunction with these publications.

Launch of Batch 10 and submissions received

Information on substances in this batch was gathered from industry and interested stakeholders through a mandatory survey notice issued under section 71 of CEPA 1999. They were also invited to complete a voluntary questionnaire.

A notice related to the launch of Batch 10 was published in May 2008 in the Canada Gazette. The section 71 notice applied to all 18 substances in this batch.
