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 (CEPA 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

Two substances in this batch have been included in final orders to add to Schedule 1.

Rescinding requirements under the Significant New Activity provisions

In July 2017, the requirements under the Significant New Activity (SNAc) provisions for Disperse Orange 5 (CAS RN 6232-56-0) were rescinded. Disperse Orange 5 was subject to the SNAc provisions as a result of the 2009 assessment of substances in this batch. Disperse Orange 5 has since been included in the Certain Azo Disperse Dyes subgroup, and the March 2017 assessment of that subgroup concluded that this substance is no longer of concern to the environment. An order was published in the Canada Gazette, Part II: Vol. 151, No. 14 – July 12, 2017 (PDF version – 4,707 K) rescinding the requirements under the SNAc provisions of CEPA 1999 for this substance.

Applying Significant New Activity provisions

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

Three orders have been published regarding the application of the SNAc provisions to 3 substances in this batch.

In January 2017, a notice of intent to amend the Domestic Substances List (DSL) to vary the SNAc requirements for TCEP (CAS RN 115-96-8) was published in the Canada Gazette, Part I. The proposed amendment is an outcome of the SNAc review. The DSL amendment is not in force until the final order is adopted by the Minister of the Environment pursuant to subsection 87(3) of CEPA 1999. The final order will be published in the Canada Gazette, Part II. Any current SNAc requirements remain in effect until such time as the final order is published.

For additional guidance on submitting information required as part of SNAc requirements , please see the Guidelines for the Notification and Testing of New Substances: Chemicals and Polymers.

The final screening assessments concluded that 2 substances in this batch meet 1 or more criteria in section 64 of 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.

Draft screening assessments and risk management scopes

New information was received from industry or interested stakeholders for each of the 19 substances in this batch. In February 2009, the draft screening assessments were released and the related notices were published in the Canada Gazette, Part I: Vol. 143, No. 8 - February 21, 2009 (PDF version - 1,519 K). Risk management scope documents were also released in conjunction with these publications.
