Substance Groupings Initiative

The following substances in this Batch have been included in the Aromatic Azo and Benzidine-based Substance Grouping under Substance Groupings Initiative as part of the second phase of the Chemicals Management Plan. As outlined in the Notice of intent for the Aromatic Azo and Benzidine-based Substance Grouping, it was recognized that assessments and conclusions pertaining to some of the substances in the grouping may be subsequently updated as part of the subgroup assessment. The latest updates on these substances are found on the respective Substance Groupings Initiative pages.

Risk Management Action Milestones

The Risk Management Action Milestones table outlines the risk management actions that were proposed for the chemical substances 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

Three 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.

Two Orders have been published addressing seven substances in this batch through the application of Significant New Activity (SNAc) provisions.

In January 2017, a Notice of Intent to amend the Domestic Substances List (DSL) to vary the SNAc requirements for Michler's ketone (CAS RN 90-94-8) and n-BGE (CAS RN 2426-08-6) was published in the Canada Gazette, Part I. The proposed amendments are an outcome of the SNAc Review. The amendments are 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 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 Solvent Yellow 18 (CAS RN 6407-78-9) and Pigment Yellow 60 (CAS RN 6407-74-5) were rescinded. Solvent Yellow 18 and Pigment Yellow 60 were subject to the SNAc provisions as a result of the 2010 assessment of Batch 7 of the Challenge. Solvent Yellow 18 has since been included in the Certain Azo Solvent Dyes subgroup, and Pigment Yellow 60 have since been included in the Certain Monoazo Pigments subgroup, and the 2016 assessment of those subgroups concluded that Solvent Yellow 18 and Pigment Yellow 60 do 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 these two substances.
