Risk Management Action Milestones

The Risk Management Action Milestones table outlines the risk management actions that were proposed for each 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 documents for these substances. For the complete wording of these proposed actions, please refer to the risk management approach documents.

Adding Substances to Schedule 1 of the Canadian Environmental Protection Act

Nine substances in this batch were proposed to be added to Schedule 1. One substance, CHPD, was proposed to be added to Schedule 1; however new evidence in the form of data on bioaccumulation has led to the re-evaluation of the risks, conclusions and final decision previously published. The former recommendation to add CHPD to Schedule 1 of CEPA 1999 is annulled. Therefore, five substances and one group of three substances in this batch have been included in final Orders to add to Schedule 1.

• Final Order adding five substances and one group of three substances:  Canada Gazette, Part II: Vol. 144, No. 10 - May 12, 2010 ( PDF Version - 3896 K)
  • Corresponding proposed Order:  Canada Gazette, Part I: Vol. 142, No. 38 - September 20, 2008 ( PDF Version - 693 K)

Applying Significant New Activity (SNAc) Provisions

Four substances in this batch have been addressed through the application of Significant New Activity (SNAc) provisions. One Order has been published.

• Order amending the Domestic Substances List that applies to four substances:  Canada Gazette, Part II: Vol. 145, No. 26 – December 21, 2011 ( PDF Version - 7720 K)

Final Screening Assessments and Risk Management Approaches

In September 2011, the revised final screening assessment report on CHPD was released. The Notice relating to this release was published in the  Canada Gazette, Part I: Vol. 145, No. 37 - September 10, 2011 ( PDF Version - 1147 K). This publication is pursuant to a  Notice of objection, received in November 2008, concerning the  proposed Order adding CHPD to Schedule 1 to the Canadian Environmental Protection Act, 1999.

In July 2008, the final screening assessment reports for this batch were released. Notices relating to this release were published in the  Canada Gazette, Part I: Vol. 142, No. 27 - July 5, 2008 ( PDF Version - 1232 K). Proposed risk management approach documents were also released on these dates for the substances in this batch which met the criteria in section 64 of CEPA 1999.

The final screening assessments (published in July 2008) concluded that nine substances in this batch meet one or more criteria in section 64 of CEPA 1999. The Government proposed to add these substances to Schedule 1 of the Act. However, new evidence in the form of data on bioaccumulation has led to the re-evaluation of the risks, conclusions and final decision previously published for one of these substances, CHPD. The former recommendation to add CHPD to Schedule 1 and to the  Virtual Elimination List is annulled.

Comments, and the Government's response, relating to general themes are summarized in the  Summary of Public Overarching Comments Received on the Proposed Risk Management Approach Documents for Batch 1.

Draft Screening Assessment Reports and Risk Management Scopes

New information was received from industry or interested stakeholders for each of the 15 substances in this batch. In January 2008, the draft screening assessment reports were released and the related Notices were published in the  Canada Gazette, Part I: Vol. 142, No. 3 - January 19, 2008 ( PDF Version - 921 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 Government of Canada's Draft Screening Assessment Reports and Risk Management Scope Documents for Batch 1 Substances of the Challenge.

New evidence in the form of data on bioaccumulation has led to the re-evaluation of the risks, conclusions and final decision previously published regarding one substance (CHPD). The previous draft screening assessment published in July 2008 is annulled. In July 2010, the draft screening assessment report was released. A Notice relating to this release was published in the  Canada Gazette: Vol. 144, No. 27 - July 3, 2010 ( PDF Version - 1709 K) for a 60-day public comment period from July 3, 2010 to September 1, 2010.

Launch of Batch 1 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 1 was published in February 2007 in the Canada Gazette. The section 71 Notice applied to 13 of the 15 substances in this batch. The remaining two substances (CAS Nos. 91-20-3 and 54079-53-7) had been surveyed under a previous section 71 Notice, and the Government had obtained sufficient information. They were therefore not included in the February 2007 Notice.

• Technical information:  Canada Gazette, Part 1: Vol. 141, No. 5 - February 3, 2007 ( PDF Version - 507 K).
• Section 71 Notice:  Canada Gazette, Part I: Vol. 141, No. 5 - February 3, 2007 ( PDF Version - 507 K).
