Final Screening Assessments and Risk Management Approaches

In August 2009, the final screening assessment reports for 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. 31 - August 1, 2009 (PDF Version - 1,153 K).

The final screening assessments concluded that three 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 this date 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 4.

For the remaining two substances in this batch (CAS Nos. 75-28-5 and 106-97-8), the assessment that was conducted evaluated the exposure to and potential risk from 1,3-butadiene in butane containing 1,3-butadiene and isobutane containing 1,3-butadiene. A screening assessment of the chemical substances butane and isobutane will be conducted at a later stage in the Chemicals Management Plan to see if additional action is needed.  For information on ongoing risk management activities for 1,3-butadiene, please refer to the following document: Ongoing Risk Management Activities for 1,3-Butadiene.

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 January 2009, the draft screening assessment reports were released and the related Notices were published in the Next link will take you to another Web site Canada Gazette, Part I: Vol. 143, No. 4 - January 24, 2009 (PDF Version - 1,121 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 Next link will take you to another Web site Summary of Overarching Public Comments Received on the Government of Canada's Draft Screening Assessment Reports for Batch 4.
