Final Screening Assessments and Risk Management Approaches

In September 2011, the final screening assessments for the remaining four substances in this batch were released in the Canada Gazette, Part I: Vol. 145, No. 37 - September 10, 2011 (PDF Version - 1,147 K).

In November 2009, the final screening assessments for 14 of the 18 substances in this batch were released in the Canada Gazette, Part I: Vol. 143, No. 48 - November 29, 2009 (PDF Version - 714 K).

The final screening assessments concluded that two substances in this batch meet one or more criteria in section 64 of the CEPA 1999. The Government proposed to add these substances to Schedule 1 of the Act. Proposed risk management approach documents were also released for the substances in this batch which met the criteria in section 64 of CEPA 1999.

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 May 2009, the draft screening assessments were released and the related Notices were published in the Canada Gazette, Part I: Vol. 143, No. 22 - May 30, 2009 (PDF Version - 818 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 assessments and risk management scope documents are summarized in the Summary of Overarching Public Comments Received on the Draft Screening Assessments and the Risk Management Scope Documents for Batch 6.

In October 2010, a Notice relating to the release of the draft screening assessments for the four remaining substances in Batch 6 (CAS Nos. 85-86-9, 6358-57-2, 7147-42-4 and 19800-42-1), was published in the Canada Gazette, Part I: Vol. 144, No. 40 - October 2, 2010 (PDF Version - 1,571 K).

New content has been added regarding the human health aspects of the assessments and has led to the re-publication of the draft screening assessments on these substances in order to allow a public comment period on the updated content. Risk management scope documents were also released in conjunction with these publications.

Launch of Batch 6 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 6 was published in May 2008 in the Canada Gazette. The section 71 Notice applied to all 18 substances in this batch.
