Final Screening Assessments and Risk Management Approaches

In October 2008, the final screening assessment report for one substance (bisphenol A) in this batch was released. A Notice relating to this release was published in the Next link will take you to another Web site Canada Gazette, Part I: Vol. 142, No. 42 - October 18, 2008 (Next link will take you to another Web site PDF Version - 504 K).

In January 2009, the final screening assessments reports for the remaining 16 substances in this batch were released. Notices relating to this release were published in the Next link will take you to another Web site Canada Gazette, Part I: Vol. 143, No. 5 - January 31, 2009 (Next link will take you to another Web site PDF Version - 1057 K).

The final screening assessments concluded that nine substances in this batch meet one or more criteria in section 64 of the Canadian Environmental Protection Act, 1999 (CEPA 1999). The Government proposed to add these substances to Schedule 1 of the Act. 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.

Comments, and the Government's response, relating to general themes are summarized in the Next link will take you to another Web site Summary of Overarching Public Comments Received on the Proposed Risk Management Approach Documents for Batch 2.

Draft Screening Assessment Reports and Risk Management Scopes

New information was received from industry or interested stakeholders for each of the 17 substances in this batch. In April and May of 2008, the draft screening assessment reports were released and the related Notices were published in the Canada Gazette. Risk management scope documents were also released in conjunction with these publications:

Launch of Batch 2 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.

Two Notices related to the launch of Batch 2 were published in May 2007 in the Canada Gazette. The section 71 Notice applied to 15 of the 17 substances in this batch. The remaining two substances (CAS Nos. 732-26-3 and 15086-94-9) had been surveyed under a previous section 71 Notice, and the Government had obtained sufficient information that they were not included in the May 2007 Notice.
