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. 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 of the Canadian Environmental Protection Act

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

Applying Significant New Activity (SNAc) Provisions

View the Comprehensive Listing of Substances that are Subject to a Significant New Activity Notice.

Three substances in this batch were to be addressed through the application of Significant New Activity (SNAc) provisions. One Order and two 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 An Order amending the Domestic Substances List for hydrazine will not be published.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

Although CAS No. 10393-49-4 is not included in the Challenge, for the purpose of substance identification, two CAS No for cobalt sulfate are included in the mandatory Section 71 Notice (see below). CAS No. 10124-43-3 is used for cobalt (II) sulfate, with a 1:1 cobalt-to-sulfate ratio, and CAS No. 10393-49-4 is used where the specific cobalt ion was not identified, or the ratio between the acid and cobalt is unknown.

Final Screening Assessments and Risk Management Approaches

In January 2011, the final screening assessment reports for substances in this batch were released in the Canada Gazette, Part I: Vol. 145, No. 3 - January 15, 2011 (PDF Version - 1,619 K).

The final screening assessments concluded that one substance in this batch meets one or more criteria in section 64 of the Canadian Environmental Protection Act, 1999 (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.

Draft Screening Assessment Reports 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 assessment reports were released and the related Notices were published in the Canada Gazette, Part I: Vol. 144, No. 26 - June 26, 2010 (PDF Version - 1,699 K). Risk management scope documents were also released in conjunction with these publications.

Comments and the Government's response relating to general themes on the draft screening assessment reports and risk management scope documents are summarized in the Summary of Overarching Public Comments received on the Draft Screening Assessment Reports and Risk Management Scope on the Challenge substances in Batch 10.

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.
