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

Four substances in this batch have been included in final Orders to add to Schedule 1.

Applying Significant New Activity Provisions

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

Seven substances in this batch have been addressed through the application of Significant New Activity (SNAc) provisions. Three Orders have been published. For additional guidance on submitting information required as part of SNAc notifications, please see the Guidelines for the Notification and Testing of New Substances: Chemicals and Polymers.

Rescinding Significant New Activity Provisions

In October 2016, the SNAc provisions on Pigment Red 251 (CAS RN 74336-60-0) were rescinded. Pigment Red 251 was subject to the SNAc provisions as a result of the 2009 assessment of Batch 3 of the Challenge. Pigment Red 251 has since been included in the Certain Monoazo Pigments subgroup, and the 2016 assessment of that subgroup concluded that Pigment Red 251 does not pose a risk to the environment or human health. An Order was published in the Canada Gazette, Part II: Vol. 150, No. 21 - October 19, 2016 (PDF Version - 1,622 K) rescinding the obligations under the SNAc provisions of CEPA 1999 concerning this substance.

In August 2008, the draft screening assessments were released and the related Notices were published in the Canada Gazette, Part I: Vol. 142, No. 34 - August 23, 2008 (PDF Version - 859 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 Batch 3 Substances.
